FIELD OF INVENTION

The disclosure is directed to a temperature regulation system, in particular a temperature regulation system for regulating the temperature of a user's body. The disclosure further relates to a method for regulating temperature, in particular regulating the temperature of at least a portion of a user's body and a controller for use as part of a temperature regulation system.

BACKGROUND

Thermal comfort is driven by the temperature inside a person's body and the temperature at the surface of your body. Deep body temperature of a person is generally 37° C. and the mean skin temperature of a person is generally 33° C. People become uncomfortable in a thermal sense when the environment changes for example, increased wind or extra sunny day, or when a person moves to a cooler place. In common situations, discomfort in a thermal sense is felt by a user when the user's skin temperature changes, rather than a change in core body temperature.

Conventional chemical or electric heating systems used in clothing can easily deliver heat at relatively high levels. Most currently available devices consist of a wearable garment with heating pads that can be manually adjusted by the user. In at least some devices the heating pads produce an equal heat output and all the heating pads are activated to provide heat. Existing products are often bulky, heavy, require manual operation and are limited in their range of operation.

DETAILED DESCRIPTION

The disclosure relates to a temperature regulation system, a controller for use as part of a temperature regulation system and a method for regulating a user's temperature. The temperature regulation system comprises at least a temperature sensor, a heating element and a controller in electronic communication with the temperature sensor and the heating element. The temperature regulation system is a wearable temperature regulation system, and as such comprises a wearable garment. At least the temperature sensor and the heating element are disposed on a wearable garment. The wearable garment is an article of clothing that can be worn by a user. In particular the temperature regulation system is adapted to control the skin temperature of a portion of user's body.

Various embodiments will now be described with reference to the figures.

FIG. 1 shows a schematic of a generalized temperature regulation system. As shown in FIG. 1, the temperature regulation system 100 comprises a temperature sensor 102, a heating element 104, a controller 106 and a user device 108. The system further comprises a wearable article 110. As shown in FIG. 1, at least the temperature sensor 102 is disposed on the wearable article such that the temperature sensor 102 is in contact with a portion of the user's body. The temperature sensor 102 is at least directly in contact with the user's skin. Alternatively the temperature sensor 102 is indirectly in contact with the user's skin, for example through a layer of the wearable garment or article 110. The sensor 102 is configured to measure the skin temperature of the user.

The wearable garment 110 can be any suitable garment 110 that a user can wear on a portion of the user's body. For example the garment 110 can be a long sleeve shirt, T-shirt, hat, socks, gloves, pants, tights, jacket, beanie or any other suitable wearable garment.

The temperature sensor 102 is configured to generate a temperature measurement that corresponds to the temperature at a portion of the user's body. Preferably the temperature measurement is a skin temperature.

The heating element 104 can be any suitable element or device to provide heat to a user. For example the heating element 104 may be a heating pad that can be positioned on the wearable garment 110 and arranged in direct contact with the user's skin or in contact through a layer of textile, to provide heat to a portion of the user's body. The heating element 104 provides heat to increase the skin temperature of the user. Alternatively the heating element can be an air conditioning unit in a car or home or can be a smart appliance or a HVAC system of a building or any other suitable device or system to provide heat to a user.

The controller 106 is configured to receive the temperature measurement from the temperature sensor 102. The controller 106 is in electronic communication with the temperature sensor 102 and the heating element 104. The controller 106 can be connected by an electrical wire or wirelessly with the temperature sensor 102 and the heating element 104. The controller receives the temperature measurement as an electronic signal from the temperature sensor 102. The controller is configured to process the temperature measurement. The controller is configured to compare the temperature measurement with a threshold temperature and generate an output. The controller 106 activates the heating element 104 if the temperature measurement i.e. the measured temperature of a portion of the user's body is below the threshold temperature. The controller activates the heating element 104 until the temperature measurement exceeds the threshold temperature. The heating element 104 is deactivated by the controller 106 when the temperature measurement exceeds the threshold temperature. In some other examples, this threshold temperature, may also be a variable with a suitable value that can be used to determine when the heating element 104 (or in some examples, a cooling element) is activated. In this regard, the threshold may be a threshold temperature, although it may also be a score or summation result that is calculated based the parameters measured.

The controller 608 receives a temperature measurement from each temperature sensor 604a-604h, compares the temperature measurement with a threshold temperature and selectively activates a heating pad 606a-606h that is associated with the sensor that provided a temperature measurement that was less than the threshold temperature. The controller 608 activates one or more heating pads 606a-606h if the temperature measurement is less than the threshold temperature. The controller 608 is removably connected to the garment 602. The controller 608 is shape and structured such that connections with the data lines and power lines can be made or broken with ease for example via a single action or motion.

The temperature sensors and heating pads disposed on the sock 902. As shown in FIG. 9, the sock 902 includes two temperature sensors 904a-904b.

The structure and operation of the controller for the temperature regulation system will now be described with respect to FIGS. 10 to 12. FIG. 10 shows a controller 1000. The controllers 106, 208, 408, 608, 808 and 908 are similar to each other. Controllers 106, 208, 408, 608, 808, 908 all have a structure that is the same as controller 1000 described with respect to FIG. 10. Controllers 208, 408, 608, 808 and 908 are structured like controller and function like controller 1000. Controller 1000 is a generalized controller that can be used in any embodiment of the temperature regulation system.

FIG. 10 shows a generalized schematic of the controller 1000 in communication with temperature sensors 1004a-1004c, a plurality of heating pads 1006a-1006c, an environmental sensor 1008 and a motion sensor 1010. The temperature sensors 1004a-1004c are a representation of the temperature sensors from earlier embodiments. Heating pads 1006a-1006c are a representation of the heating pads from earlier embodiments. The environmental sensor 1008 and motion sensor 1010 are representations of the motion sensors and environmental sensors from earlier embodiments. The sensors shown in FIG. 10 are generic representations to illustrate operation of the generalized controller 1000. The functionality of the controller and interaction with the sensors and user device is applicable in any of the earlier embodiments described.

As shown in FIG. 10, controller 1000 comprises a processor 1022, a memory unit 1024 and a power unit 1026. The controller 1000 is a microcontroller i.e. includes all components on a single chip or integrated circuit. The processor 1022 is a microprocessor that can process electronic commands. The processor 1022 can execute commands stored in the non-transitory computer readable memory unit 1024. The processor 1022 is preferably in the form of an integrated circuit. The memory unit 1024 comprises ROM 1028 and RAM 1030. The power unit 1026 includes one or more rechargeable batteries that are disposed in a casing and in communication with the processor. The controller 1000 also includes other essential electronic components for interfacing the various components described and appropriate interfacing circuitry.

The controller 1000 further includes a communication module 1032. The communication module 1032 is low energy wireless system such as a Bluetooth module. The communication module 1032 is in electronic communication with the processor 1022 and allows the controller 1000 to communicate a user device 1016.

The user device 1016 has an app that is executable on the user device that allows communication between the user device 1016 and the controller. The app also allows for a user to access an interface that allows a user to input user parameters (as described earlier) as well as additionally modify controller operating modes.

The controller 1000 is also in communication with a plurality of temperature sensors and heating pads that are disposed on a wearable garment. The controller 1000 is configured to receive a temperature measurement from a temperature sensor. The temperature measurement relates to a skin temperature of the user. The controller 1000 is further configured compare the temperature measurement with a threshold temperature and activate a heating pad if the temperature measurement is less than the threshold temperature. The temperature measurement relates to the temperature at a portion of a user's body. The controller continuously receives temperature measurements. The controller 1000 deactivates the heating pad once the temperature measurement exceeds the threshold temperature. It should be noted that the temperature sensors described herein measure the skin temperature but alternative sensors can be used that allow other temperature measurements such as muscle temperature or core temperature and so on.

As disclosed in the earlier embodiments each temperature sensor is associated with a heating pad. The controller 1000 receives a plurality of temperature measurements, each temperature measurement being received from a single temperature sensor. The controller 1000 compares each temperature measurement with a threshold temperature. The controller 1000 activates the specific heating elements that are associated with the temperature sensors that detect a temperature measurement that is lower than the threshold temperature. The controller 1000 allows for localized or selective heating of specific portions of the user's body to heat.

Optionally in an operating mode, the controller 1000 may be configured to determine a temperature profile along the user's body. The temperature profile is a distribution of temperatures across or along the various portions of the user's body. The temperature profile can be transmitted to a user device 10 for display to the user to indicate which parts of the user's body are cooler. Temperature and heat distribution across each user is different, and various parts of a user's body cool at differing rates. The controller of the temperature regulation system detects such changes based on the temperature measurements from the various temperature sensors e.g. 1004a-1004c (or any of the sensor arrangements described earlier) to calculate the temperature or heat distribution profile on a user's body. The controller 1000 is advantageous because heat is applied to localized areas of the user's body that require further heating. One example could be in cold climates the extremities of a user's body cool more rapidly than the core of the user's body. The use of any one of the temperature regulation system embodiments disclosed and in particular the controller, allows the system to provide heat to the extremities of the user's body to heat them, thus reducing the physiological work needed to heat the user's extremities. This allows for more efficient blood flow in the user's body and reduced physiological work.

Optionally in a further operating mode the controller 1000 may also determine an average body temperature based on the various temperature measurements from temperature sensors 1004a-1004c. The average temperature may be a mean temperature value or a median temperature value. The average temperature value provides an indication of overall body temperature. The mean of the various temperatures may be the mathematical mean. The median of the various temperature measurements may be the mathematical median.

In at least one embodiment the mean temperature can be calculated based on weighted temperature measurements. In this alternative each temperature measurement may be attributed a weighting. The weighting is in the form of a coefficient that is associated with each temperature measurement from each temperature sensor. The coefficient (i.e. weighting) is dependent on the location of the sensor on the user's body or the surface on the user's body. The controller 1000 is configured to assign an appropriate coefficient to each temperature measurement based on the location of the temperature sensor that has provided the temperature measurement. The controller may include a pre-determined mapping of the temperature sensor locations that is used to determine the location of the temperature measurement. In one example the temperature measurements from the user's extremities may be assigned a higher coefficient as compared to temperature measurements from the torso of the user's body. The coefficients may be reflective of thermal sensitivity of the user's skin i.e. a higher coefficient is assigned to locations that are more likely to have greater temperature fluctuations or locations that are likely to cool faster than other locations of the user's body. The coefficients assigned to temperature measurements may also be based on a thermal sensitivity measure as described, the thermal sensitivity acting as a further input. In a further alternative the coefficients may be customized for each user based on initial user information such as which locations of the user are most susceptible to rapid thermal or temperature change.

The controller 1000 is configured to compare the average temperature with a threshold temperature. If the average temperature is less than the threshold temperature the controller activates all the heating pads 1006a-1006c to heat the user's body. All the heating pads 1006a-1006c are activated to the same intensity level.

The controller 1000 is configured to provide an activation signal along the power lines to the heating pads 1006a-1006c. The activation signal is preferably a pulse width modulated (PWM) power signal. The processor 1022 includes a PWM module 1034 integrated into the processor or connected to the processor and the power unit. The PWM module generates a PWM signal and transmits such along the power lines to the heating pads 1006a-1006c. A PWM signal conserves the power from the power unit.

A threshold temperature is determined by the controller 1000. The controller 1000 first determines a reference temperature. The reference temperature relates to a reference body temperature of the user. The reference temperature preferably relates to a reference skin temperature of the user. The reference temperature can be the initial or reference skin temperature of a portion of the user's body. The reference temperature is determined during a calibration process. The calibration process takes place during start-up of the system and takes place in a comfortable environment. A comfortable environment is an environment in which the user feels comfortable with respect to body temperature i.e. a thermally comfortable environment. This may be a subjective parameter i.e. comfort for each user varies. The user can initiate a calibration process by activating a push button on the controller 1000 or by selecting a calibration mode via the user device 1016.

The temperature regulation system as described is advantageous because the system determines a temperature distribution across a user's skin and selectively energizes or activates a heating pad in the location where the temperature is less than a threshold temperature. This is further advantageous because power consumption is reduced. Further the temperature regulation system as described is also advantageous because the system takes into account various factors or parameters that can affect a person's thermal comfort or sense of comfort. For example the system actively modifies the threshold temperature based on environmental parameters, movement of the user and specific user parameters such as age, gender and cold sensitivity.

FIG. 11 shows an embodiment of the calibration process 1100. The calibration process is an initial threshold setting process. At step 1101 an initial body temperature measurement is obtained by the controller from a temperature sensor. This initial body temperature measurement is stored by the controller. In one form the initial body temperature is an average body temperature based on the multiple temperature measurements from the multiple sensors 1004a-1004c (or other sensors described earlier). It should be noted that the body temperature is a skin temperature as described herein. Alternatively the initial body temperature corresponds to the lowest temperature measurement value obtained by the controller 1000. In a further alternative embodiment the temperature measurements may be provided as plurality or list of independent temperature measurements. The initial temperature may be measured for each body location. Preferably the controller is configured to record and store an initial temperature for each location on the body.

At step 1102 an initial ambient temperature measurement is obtained from the user device 1016 based on local weather information available at the user device 1016. The ambient temperature measurement is recorded and stored within the memory unit 1024. The controller 1000 can also record and store a time of day measurement. This ambient temperature measured in a comfortable environment can be set or stored as a base ambient temperature. Any changes in ambient temperature can be assessed in relation to the base ambient temperature by the controller to adjust the threshold temperature, as described later.

At step 1103 an initial relative humidity measurement is obtained by the controller 1000 from an environmental sensor 1008. The relative humidity relates to the humidity in the comfortable environment. The relative humidity measurement is stored within the memory unit 1024.

At step 1104 a plurality of fixed user parameters are obtained by the controller 1000. The fixed user parameters are unchanging parameters associated with the user. These parameters are most likely to remain unchanged for extended periods of time. At step 1104 the unchanging parameters gathered by the controller 1000 are gender, age, body surface area and cold sensitivity. The user enters age and gender into the user device 1016 as part of the calibration process. The age and gender information is stored within the memory unit 1024 of the controller 1000.

The body surface area is determined by the user based on the height and weight of the person. The body surface area is input via the user device 1016. Cold sensitivity is entered by the user via the user device 1016. Cold sensitivity is selected from a predetermined numerical scale, the scale being related to a thermal comfort scale. The user selects from −2, −1, 0, +1, +2, wherein −2 relates “not cold sensitive at all” and +2 relates to “very cold sensitive”. This is a subjective measure and the user selects cold sensitivity parameter from the predefined scale.

At step 1105 the controller 1000 determines the threshold temperature by using the reference temperature labelled T herein. Below are examples of how the threshold temperature can be determined using the reference temperature and one or more of ambient temperature, initial relative humidity, user parameters. Preferably the controller 1000 determines a unique threshold temperature at each location on the user's body based on the above described parameters and individual initial temperature measurements.

In one example the threshold temperature is the reference temperature T minus 0.025° C. T−0.025° C. is considered the base threshold temperature, where there are no other sensors or parameters used. The embodiments of the temperature regulation system as described earlier include an environmental sensor, motion sensor and user parameters. Measurements or inputs from these can be used to adjust the threshold temperature.

The reference temperature T is adjusted based on one or more default parameters. The default parameters are any one or more of relative humidity, ambient temperature, cold sensitivity, age, gender and body surface area. The threshold temperature is determined based on the reference temperature and any one or more other parameters that are available to the controller.

Following is a description of the changes to the reference temperature to define a threshold temperature at step 1105. The reference temperature T is raised by 0.025° C. if the user is 60 or older, or the reference temperature T is lowered by 0.025° C. if the user is 59 or younger. The reference temperature is raised by 0.025° C. if the user is a man since men are better at retaining heat. The reference temperature is lowered by 0.025° C. if the user is a female because women are found to feel colder. The reference temperature is lowered by 0.025° C. if the body surface area is greater than 1.8 m².

The reference temperature T is also modified based on the cold sensitivity parameter in order to determine a threshold temperature. In one example if the cold sensitivity parameter is −2 or −1 then the reference temperature is raised by 0.025° C. If the cold sensitivity parameter is +1 or +2 then the reference temperature T is lowered by 0.025° C. If the cold sensitivity parameter is 0, then there is no change to the reference parameter.

The changes to the reference temperature are cumulative to determine a threshold temperature. The threshold temperature is determined as a sum of all the changes to the reference temperature based on one or more of the default parameters.

FIG. 12 shows a method 1200 of operation of the controller 1000 when in use. At step 1201 a threshold temperature is determined. The threshold temperature is determined using the method described with respect to FIG. 11. At step 1202 the controller receives temperature measurements from the one or more sensors 1004a-1004b of the temperature regulation system. As described, the sensors can be as per any one of the embodiments described earlier. At step 1203 the controller compares the temperature measurement with the threshold temperature. If the temperature measurement is less (i.e. YES) than the threshold temperature then at least one of the heating pads 1006a-1006c are energized, as per step 1204. The heating pad provides heat to the skin of the user's body when energized to increase the skin temperature of the user. If the temperature measurement is higher or greater than the threshold temperature then the method returns to step 1201. Following step 1204 the method returns to step 1201. The controller 1000 is configured to measure each temperature measurement and compare each temperature measurement with a unique corresponding threshold temperature. Each threshold temperature corresponds to a location on the user's body and each temperature measurement also corresponds to a location on the user's body. The controller 1000 selectively activates a heating pad that corresponds to a temperature sensor that measures a temperature less than a corresponding threshold temperature.

In its simplest form the threshold is considered to be the reference temperature T minus 0.025° C. (i.e. T−0.025). The controller 1000 is configured to compare the temperature measurement with the threshold temperature for at least one sampling period i.e. compare at least two consecutive temperature measurements. For example if the temperature measurement is less than the threshold for 2 seconds or for two or more consecutive measurements, then the method proceeds to step 1204. The controller 1000 is configured to determine the threshold temperature. The threshold temperature is determined by the controller for each user, i.e. each user will have a unique threshold temperature associated with a user.

The system can optionally adjust the threshold temperature during method 1200 based on one or more adjustment parameters. Adjustment parameters are one or more parameters measured by other sensors within the temperature regulation system such as an environmental sensor, a motion sensor. Adjustment parameters also include user parameters that can be entered by the user through the user device.

FIG. 12 further shows optional steps of method 1200 that are directed to the adjustment of the threshold temperature. Referring to FIG. 12 the method 1200 comprises an optional step 1205, in which, the controller determines if a relative humidity measurement is received. If NO, then the method proceeds to step 1202. If YES, the controller monitors change in humidity for at least a minute at step 1206. At step 1207 the controller determines if the humidity increases by 10% for 1 minute. If YES, then the controller proceeds to step 1208 to modify the threshold temperature by a pre-determined value. If YES, at step 1207 the threshold temperature is lowered by 0.025° C. If the test at step 1207 results at NO, then the controller proceeds to step 1209. At step 1209 the controller determines if the relative humidity decreases by more than 10% for more than 1 minute. If YES, then the method proceeds to step 1208, where the threshold temperature is modified, i.e. the threshold temperature is increased by 0.025° C. If NO at step 1209 then the threshold temperature is not changed and the optional method returns to step 1202.

The method 1200 comprises an optional step 1210, in which, the controller 1000 determines if a movement measurement is received from a motion sensor. If step 1210 returns a YES, the controller monitors movement of the user at step 1211. As described earlier the motion sensor determines movement of the user i.e. speed of the user. Additionally or alternatively the motion sensor can also detect a heart rate of the user. At step 1211 the controller determines if the movement increases by more than 10% for more than 1 minute or the speed of the user increases by more than 10% for more than 1 minute or the heart rate increases by more than 10% for more than 1 minute. If YES, then the method proceeds to step 1208 to modify the threshold temperature by a modified or predetermined value. The modifier or predetermined value is 0.035° C., and the threshold temperature is decreased by 0.035° C. This is because users can tolerate a skin temperature that is colder skin temperatures when exercising because the deep body temperature of the user increases with movement. The motion sensor can be an accelerometer as described earlier and allows the controller 1000 to determine the intensity and duration of the movement of the user. If at 1211, the method determines a NO output, then the method can proceed to the next optional step or directly to step 1202, and the threshold temperature is not modified or adjusted. In general the threshold temperature is reduced if the relative humidity increases as user's feel colder in high humidity weather. Therefore the controller is configured to activate the heating pad at a lower temperature to account for the perception of a colder temperature. The heating pad needs to be activated earlier to prevent the user from feeling too cold. The threshold temperature is an activation temperature, at which the heating pad is activated.

Alternatively the threshold temperature can be increased if the humidity is increased, such that the heating pad is activated at a higher temperature. The threshold temperature can be increased if the humidity increases depending on specific user parameters such as age, gender or thermal sensitivity. For example if the user is not very thermally sensitive then the controller is configured to raise the threshold temperature when the humidity increases, since the user does not feel overly cold.

The method includes a further optional step 1212, in which, the controller 1000 determines if an ambient temperature is received from an environmental sensor. Ambient temperature is an environmental measurement. If step 1212 returns a YES, the controller determines ambient temperature at step 1213. At step 1213 the controller determines if the ambient temperature is greater than 25° C. If YES the method proceeds to step 1208 to modify the threshold temperature by a modifier or a predetermined value. The predetermined value is 0.025° C. If at step 1213 the method returns a NO, the method proceeds to step 1214. At step 1214 the controller determines if the ambient temperature is less than 15° C. If YES, then the method proceeds to step 1208 and the threshold temperature is reduced by 0.025° C. If NO, then the method proceeds to step 1202 (not illustrated for clarity).

In an alternative embodiment the threshold temperature is increased if the ambient air temperature increases above a base ambient temperature. For example if the base ambient temperature is 20° C., and the measured ambient air temperature is above 25° C. the threshold temperature is raised by 0.025° C. If the measured ambient air temperature is above 30° C. the threshold temperature is raised by 0.025° C. If the ambient air temperature is above 35° C. the threshold temperature is raised by 0.025° C. Conversely if the ambient air temperature is less than 15° C. the threshold temperature is reduced by 0.025° C. If the ambient air temperature is less than 10° C. the threshold temperature is reduced by 0.025° C. If the ambient temperature is less than 5° C. the threshold temperature is reduced by 0.025° C.

In an alternative embodiment the threshold temperature may be modified in a cumulative manner if the ambient air temperature is greater or less than the base ambient temperature. For example in this embodiment the base ambient temperature is 20° C. If the ambient air temperature is above 25° C. the threshold temperature is raised by 0.025° C. If the ambient air temperature is above 35° C. the threshold temperature is raised by 0.025° C., meaning the threshold temperature is raised by a total of 0.05° C. If the ambient air temperature is above 35° C. the threshold temperature is raised by 0.025° C., meaning the threshold temperature is raised by a total of 0.075° C. The threshold temperature is cumulatively increased by the modifier. In this example the threshold temperature is increased by 0.025° C. every time the ambient temperature is increased by 5° C., once the ambient temperature exceeds the base ambient temperature. The threshold temperature may not be changed if the ambient temperature is less than or drops below the base ambient temperature. Alternatively the threshold temperature can be reduced by a modifier of 0.025° C. every time the ambient temperature is reduced by 5° C. following a reduction compared to a base ambient temperature. This will mean that in an example operation, if a user is comfortable with a skin at 32° C., when the humidity is at 50%. If the skin cools to 30° C., the heating pads may be activated. If the detected humidity increases from 50 to 80%, the pads may also be activated when the skin cools from 32 to 31° C. This is so as to achieve a desirable outcome as users tend to feel colder when humidity is higher when air temperature remains constant.

In an alternative embodiment the controller is configured to increase the threshold temperature if the ambient air temperature increases above a base ambient temperature, such as for example 25° C. The threshold temperature (i.e. the activation temperature of the heating pads) is increased by 0.025° C. If the ambient air temperature is increased above 30° C., then the controller is configured to raise the threshold temperature by 0.025° C. If the ambient air temperature increases above 35° C., the controller is configured to increase the threshold temperature (i.e. the activation temperature) by 0.025° C. The base ambient temperature can be the ambient temperature measured during the threshold setting process 1100 described with respect to FIG. 11. The initial ambient temperature measured while measuring the reference body temperatures is measured in a comfortable environment, hence is the a good measure of a base ambient temperature. However if the ambient temperature is less than a base ambient temperature for example less than 15° C. the controller is configured to maintain the threshold temperature. This is because the in light of the cooler ambient air temperature, the user's body temperature will reduce, and hence the heating pads will be activated at the a pre-set threshold time. This embodiment provides a safety mechanism that the heating pads are not energized too early when the ambient air temperature is below a base ambient temperature, and potentially providing too much heat to the user.

In some examples, if the humidity and motion measurement are detected to have changed during a predetermined period of time, a modifier may be generated with respect to this change in humidity and motion. This modifier may then be used as a weighting or otherwise an adjustment variable which can in turn be used to adjust the threshold to the appropriate amount.

The method may further proceed to optional step 1215, in which, the controller 1000 determines if a time of day information is received from a user device. If step 1215 returns YES, the controller determines a time of day at step 1216. Following the determination of the time of day, the method proceeds to step 1208 wherein the threshold temperature is modified or adjusted. The rate of threshold adjustment is based on different time of day determination that occurs at step 1216. One example of the threshold temperature modifier determination is explained below, as would occur at step 1216. If the time of day is between 10:00-11:59 or between 22:00 to 23:59, the threshold temperature is increased by 0.025° C. If the time of day is determined to be between 12:00 and 21:59 the threshold temperature is increased by 0.035° C. If the time of day is between 00:00 and 9:59 the threshold temperature is reduced by 0.025° C. because this time is considered the coldest time of the day. The threshold temperature parameter adjustment as described is advantageous it aligns with the circadian rhythm of humans in general. It is known that the body temperature (i.e. internal body temperature) is lower during the night than it is during the day. Therefore the same level of thermal comfort may be achieved in the afternoon for a lower skin temperature, and vice versa. The changes in threshold temperature (i.e. threshold temperature modifier) calculation as described is in alignment with the circadian rhythm of a user hence providing for added comfort.

At step 1208 a final threshold temperature is determined. The method proceeds to step 1203 to compare the temperature measurement with a threshold temperature, wherein the threshold temperature is the updated or modified threshold temperature determined at step 1208.

The threshold temperature is modified in a cumulative manner based on the various modifier values or predetermined values described above. The threshold temperature is adjusted by a cumulative value based on the number of adjustment parameters used.

The method comprises an additional step 1217 that proceeds after step 1212 wherein the ambient temperature measurement is received by an environmental sensor. At step 1217 the controller determines if the ambient air temperature is reducing by 0.5° C. for at least a period of time e.g. for at least 1 minute. Such a change in air temperature is a determination of a cold air event. If the a change in air temperature as described occurs, then the method proceeds to 1218 where the heating pad is activated continuously for a period of time e.g. 2 minutes or until a temperature measurement detected has increased by 0.1° C. for at least 1 minute. Step 1218 is a “super mode”. A user can select activation of the super mode by using a button on the controller 1000 or by selecting such an option on the user device 1016.

Additional optional steps for other adjustment parameters can be implemented. As disclosed in FIG. 12, the threshold temperature is customized for each user. The threshold temperature can also be updated in real time as changing environmental measurements are identified or as a change in a motion measurement is detected or as user parameters are updated automatically or by the user. Real time updating of the threshold temperatures and customized threshold temperatures are advantageous because the system continuously determines the most comfortable temperature for the user (i.e. the threshold temp) and attempts to control the heating elements such that the user is not cold or the user's skin temperatures are not less than the threshold temperature.

It will be appreciated that in the exemplary embodiments described earlier, the locations of the temperature sensors and heating pads are described with reference to major muscle groups in the human body. It will be appreciated that in alternative embodiments the temperature sensors and/or the heating pads can be aligned with any suitable portion of the human's body. For example the heating pads and/or the temperature sensors can be placed on the wearable garment such that in use, the heating pads and/or the temperature sensors are aligned with major tendons or major veins of the user. In some embodiments a heating is positioned at least along the spine of the user since the spine carries all the major nerves of the user and is a sensitive part of the body.

It will be appreciated that the heating pads as described in the exemplary embodiments can be any suitable size and shape. The size and shape can be determined by the size of the wearable garment and the specific location the heating pad should align with in use. The heating pads are preferably a polygon shape. However other customized shapes are also contemplated. It will also be appreciated that the temperature sensors can be any suitable size, shape and resolution. It will also be appreciated the temperature sensors may be configured with any required sampling frequency.

In a further alternative embodiment the controller of the temperature regulation system is configured to receive a plurality or list of independent temperature measurements from each temperature sensor. The controller is configured to determine an initial body temperature corresponding to each location on the body. A threshold temperature can be calculated for each location on the body based on any one or more measurements/parameters as described earlier, such as an environmental measurement/parameter, a motion measurement or one or more user parameters. The controller is configured to compare each temperature measurement with a unique threshold temperature and activate each heating pad independently based on the comparison. Each heating pad is independently activated if the temperature measurement is less than the threshold temperature. The heating pad that is independently activated corresponds to the temperature sensor at a specific location on the user's body. In this alternative embodiment the controller is configured to independently control each heating pad to independently heat a specific portion of the user's body based on unique or individual temperature sensor measurements. This alternative embodiment is advantageous because the entire body is heated, and specific heating pads are activated, which conserves power and provides heat where required, making the user more comfortable.

In yet another further embodiment of the disclosure, the temperature regulation system may be arranged to operate with a temperature adjustment element which includes a heating element as described above and/or a cooling element. When operating with a cooling element, similar operational logic described with reference to the controller above may apply, although modifications to operate with a cooling element with different threshold calculations may be used. Cooling elements, including, but not limited to piezoelectric cooling systems, heat pumps or transfer systems including heat sinks, fans or radiators may also be used. These embodiments may be advantageous in alternative environments where it would be desirable to achieve a cooling effect over that of a heating effect.

Although not required, the embodiments described with reference to the Figures can be implemented to file an application programming interface (API) or as a series of libraries for use by a developer or can be included within another software application, such as a terminal or personal computer operating system or a portable computing device operating system. Generally, as program modules include routines, programs, objects, components and data files the skilled person assisting in the performance of particular functions, will understand that the functionality of the software application may be distributed across a number of routines, objects or components to achieve the same functionality.

It will be appreciated a number of alternative embodiments have been described herein. It will be appreciated by persons skilled in the art that the alternative embodiments described can be used in part or wholly with any of the embodiments described with reference to the figures. It will also be appreciated that portions or elements that are known in the prior art or known to persons skilled in the art have not been explicitly described.
