  • Patent number: 10082308
    Abstract: A HVAC controller located within a building zone includes a housing, a wireless radio, a controller monitor, a temperature sensor, and a temperature compensation module. The wireless radio is contained within the housing and is configured to transmit data via a wireless HVAC network. The controller monitor is configured to detect wireless activity of the wireless radio, the wireless activity generating heat inside the housing and causing a temperature inside the housing to exceed a temperature of the building zone outside the housing. The temperature sensor is configured to measure the temperature inside the housing. The temperature compensation module is configured to determine a wireless heat rise resulting from the wireless activity, to calculate a temperature offset based on the wireless heat rise, and to determine the temperature of the building zone outside the housing by subtracting the temperature offset from the temperature measured inside the housing.

  • Patent number: 8899828
    Abstract: A heat sensor has the ability to correct for errors introduced during temperature changes of the hot junction of the thermopile for the heat sensor. For example, the effect of temperature changes at the hot junction of the heat sensor relative to the cold junction is mathematically modeled such that the effect on the temperature determination can be corrected given certain information relating to the thermopile, its electrical output, and the temperature history and current temperature of the cold junction. By accounting for these factors, a processing device can modify the temperature determination output for the heat sensor while correcting for error introduced by temperature changes at the hot junction as determined by the mathematical model.

  • Publication number: 20140010260
    Abstract: A sensor surrogate (120) for causing a heating, ventilating, and air conditioning (HVAC) system (110) to maintain a desired room temperature, contains a temperature sensor (122) for determining an actual room temperature and logic embodied on at least one non-transitory computer readable medium (130). The logic (130) is configured to perform the steps of: calculating a current low temperature that is lower than a pre-programmed HVAC system temperature and providing the HVAC system with a first signal that represents the calculated current low temperature, if the desired temperature is above the pre-programmed HVAC system temperature; and calculating a current high temperature that is above the pre-programmed HVAC system temperature and providing the HVAC system (110) with a second signal that represents the calculated current high temperature, if the desired room temperature is below the pre-programmed HVAC system temperature.

  • Publication number: 20130343423
    Abstract: A detected temperature acquiring portion acquires detected temperatures from individual thermopile array sensors, a temperature change comparing portion compares changes in detected temperatures over time, for each respective location, between test locations selected from a overlapping region and individual comparing locations for two thermopile array sensors wherein planned detecting ranges partially overlap each other, to identify a best match location, a factor estimating portion, for each test location, generates an equation indicating a relationship between the best match location and positional shift factors, and establishes these equations as a system and solves the system of equations through a least-squares method to estimate the positional shift factors, and a detecting range identifying portion corrects location coordinates of the planned detecting ranges based on these positional shift factors to identify actual detecting ranges.

  • Patent number: 8602643
    Abstract: A method and apparatus is presented for obtaining of accurate measurements of the temperature of a thermocouple and high fidelity measurements of the rate of change of the temperature of a thermocouple. A first sub-circuit is connected to the thermocouple with two conductors made of two different thermocouple alloys which are substantially the same as the alloys used in the construction of the thermocouple. A second sub-circuit is connected to the thermocouple with two conductors made of substantially identical material, such as copper. The first sub-circuit provides an accurate measurement of the temperature of the thermocouple. The second sub-circuit provides a high fidelity measurement of the rate of change of the temperature of the thermocouple.

  • Patent number: 8583311
    Abstract: A storage battery control device detects an overhead wire supply current value showing a sum of a current value output from a storage battery and a current value output from a transformer substation, and charging or discharging of the storage battery is controlled so that a charging rate of the storage battery becomes a charging rate target value when the detected overhead wire supply current value is less than a first threshold. In addition, charging or discharging of the storage battery is controlled so that the output voltage of the storage battery control device is maintained at a constant voltage control mode when the detected overhead wire supply current value is greater than or equal to the first threshold.

    Abstract: The present disclosure relates to a dosimeter for measuring exposure to heat over time in combination with peak temperature indicators and reversible temperature indicators. The preferred temperature indicator tag is credit card sized and comprises four time-temperature dosimeters. Each dosimeter has a wick in contact with a separate reservoir containing a mix of a colored dye, a wax and an amorphous polymer to indicate a distinct temperature range when the mix melts. The wicks are preferably made of porous paper with a pore size around 8 microns to allow for proper capillary action along its length. An adhesive, except where each wick contacts its respective reservoir and at a vent, preferably seals each wick. The tag preferably has a plurality of peak temperature indicators where each indicator has a blend of a dye, a wax and a polymer for a temperature indication range. The tag also preferably has a plurality of reversible temperature sensors.

    Abstract: An exemplary method of determining location information includes sensing a temperature of an object or person in a sensing field of at least one temperature sensor at each of a plurality of measurement periods. A relationship between the sensed temperature at a first one of the measurement periods and the sensed temperature at a second, later one of the measurement periods is determined. A determination is made from the determined relationship whether the object or person moved relative to the temperature sensor during a time from the first one of the measurement periods to the second one of the measurement periods.

  • Patent number: 8529682
    Abstract: Indicator inks, indicators formed by printing or otherwise utilizing the inks and host products utilizing the indicators are disclosed. Reactivity-enhancing adjuvants stimulate enhanced thermal reactivity of diacetylenic or other indicator agents capable of responding to ambient thermal conditions with a visual change signaling an end point. The diacetylenic or other agents may be sensitive or relatively insensitive to ambient temperatures. Use of a reactivity-enhancing adjuvant provides a useful means for adapting the reactivities of indicator agents to the response characteristics of prospective host products, for example perishables such as vaccines or fresh fish and maturables such as fruit, cheese and wine. Some exemplary adjuvants include low-temperature polymerization initiators, for example methyl ethyl ketone peroxide and polymerization accelerators, for example cobalt compounds. Such initiators and accelerators can also be used in combination.

  • Patent number: 8523429
    Abstract: A remote, noncontact temperature determination method and apparatus is provided, which is operable to determine the temperature of a conducting member forming a part of or in operative thermal communication with an object of interest. The method comprises the steps of first inducing a closed vortex eddy current (28) in a conducting member (16, 38, 44) by subjecting the member (16, 38, 44) to a magnetic field, such that the corresponding eddy current magnitude changes exponentially over time. A characteristic time constant of the exponential current magnitude changes is then determined, and this is used to calculate the temperature of the object. The apparatus (24) includes a field transmitting coil (14) coupled with a waveform generator (12) for inducing the eddy current (28), and a field receiving coil assembly (18) which detects the corresponding magnetic field induced by the eddy current (28).
