Moreover, a person having ordinary knowledge in the art understands that the same component/product may have a number of different names. For instance, the terms “processor” and “computing unit” refer to the same thing. Hence, components/products having functions similar to those described herein and belonging to the same technical field as the present invention fall within the scope of the present invention.

Referring to FIG. 1, there is shown a block diagram illustrating the function of a separate computing system according to the first embodiment of the present invention. As shown in FIG. 1, there is a separate computing system 100 of the present invention, comprising: a primary computing device 1 comprising a display unit 11, a computing unit 12, a memory unit 13, a signal receiving unit 14, and a power supply unit 15; and a sensing device 2 comprising a signal transmission unit 21, a sensing unit 22, and a power supply unit 23.

The sensing unit 22 of the sensing device 2 is capable of detecting a user's physiological information such as, for example, information relating to one or more of the user's blood pressure, pulse, voice, vibration, and temperature. The signal transmission unit 21 of the sensing device 2 receives a message from the sensing unit 22 and transmits externally the message via wireless communication. Preferably, the signal transmission unit 21 is selected from one of a WiFi communication unit, an NFC communication unit, a RFID communication unit, a Bluetooth communication unit, a Zigbee communication unit, and an infrared communication unit. The power supply unit 23 of the sensing device 2, which can be, for example, one of a lead-acid battery, a nickel-cadmium battery, a nickel-hydride battery and a lithium ion battery, is configured to supply power to all electronic components in the sensing device 2.

The signal receiving unit 14 of the primary computing device 1 receives information transmitted by the signal transmission unit 21 of the sensing device 2. Preferably, the signal receiving unit 14 is selected from one of a WiFi communication unit, an NFC communication unit, a RFID communication unit, a Bluetooth communication unit, a Zigbee communication unit, and an infrared communication unit. The computing unit 12 of the primary computing device 1 performs the processing or computing operation on the information received by the signal receiving unit 14, stores a result of the processing or computing operation in the memory unit 13 and/or displays the result of the processing or computing operation on the display unit 11. The computing unit 12 refers generally to a logical computing device capable of executing complex computer programs, such as an integrated circuit central processing unit or a microprocessor. The computing unit 12 can have one or more cores and is preferably capable of parallel computing or synchronous multithreaded computing. The memory unit 13 includes a volatile memory and/or a nonvolatile memory and is configured to store the data of the primary computing device 1. The power supply unit 15, which can be, for example, one of a lead-acid battery, a nickel-cadmium battery, a nickel-hydride battery and a lithium ion battery, is configured to supply power to all electronic components in the primary computing device 1. Moreover, the display unit 11 of the primary computing device 1 is selected from one of a screen, a projection device, an audio device, and at least one LED lamp.

Referring to FIG. 2, there is shown a flow chart illustrating the operation of the separate computing system according to the first embodiment of the present invention. As shown in FIG. 2, steps S21˜S22 are implemented on the sensing device 2, and steps S23˜S25 are implemented on the primary computing device 1. For the sake of better understanding of the present invention, the primary computing device 1 is exemplified by a smartphone, and the sensing device 2 is exemplified by a wristband capable of sensing physiological information. The physiological information is preferably the blood pressure-related information or pulse-related information. However, a person having ordinary knowledge in the art understands that the primary computing device 1 can be one of other mobile communication devices, such as a tablet computer, a notebook computer, a hand-held game console, and a multimedia player, and that the sensing device 2 can be a contact lens with sensing capability or a heart stent with sensing capability, without departing from the spirit and scope of the present invention. The first embodiment described herein is to be deemed as illustrative, rather than restrictive, of the scope of the present invention.

In step S21, the sensing unit 22 of the sensing device 2 senses the user's physiological information such as, for example, one of the blood pressure-related information, the pulse-related information, the estimated step count-related information, and the body temperature-related information, but not limited thereto. In step S22, the signal transmission unit 21 of the sensing device 2 transmits externally the physiological information having not yet undergone the computing and processing operations. The phrase “having not yet undergone the computing and processing operations” refers to the condition that the value detected by the sensing unit 22 is directly transmitted externally via wireless transmission without special encoding or encrypted computation. Thus, the sensing device 2 does not require any high-performance computing unit. Moreover, in practice, it is feasible to set a transmission condition for the sensing device 2, for example, under which wireless signals are regularly transmitted to the primary computing device 1 via the signal transmission unit 21, or wireless signals are transmitted externally via the signal transmission unit 21 when the sensing unit 22 senses that the subject's physiological information exceeds a critical value.

Referring to step S23, the signal receiving unit 14 of the primary computing device 1 receives the physiological information. As shown in step S24, the physiological information is then transmitted to the computing unit 12 to undergo the computing operation whose result can, for example, be used to determine whether the blood pressure-related information is within a normal range, determine whether the pulse-related information is within a normal range, calculate the calories burned or the distance walked according to the estimated step count-related information, and determine whether the body temperature-related information is within a normal range, but is not limited thereto. In step S25, the primary computing device 1 informs a user 5, via the display unit 11, of a result of the processing or computing operation which indicates whether, for example, various data relating to the user's blood pressure, pulse, calories, and body temperature are within their respective normal ranges, hence the user 5 can obtain the physiological information in a real-time manner and knows whether or not the physiological information is within a normal range. It is to be noted that the user 5 watching the display unit 11 and the subject being measured by the sensing device 2 can be the same person or different persons, and thus the separate computing system of the present invention is widely applicable to the measurement made by the physician/patient or oneself.

As can be seen from the above embodiment, certain physiological information, after being obtained by the sensing device 2, is transmitted, via wireless transmission, to the primary computing device 1 to undergo the computing and processing operations performed by the computing unit 11 of the primary computing device 1, and then the result of the computing and processing operations is displayed on a screen (i.e., the display unit 11) of the primary computing device 1. With such arrangement, the sensing device 2 is exempted from complicated processing or computing operations, and thus the number of essential components thereof can be minimized (for example, no high-performance processor or memory is required), thereby fulfilling the goals of minimized weight and low power consumption. In other words, the present invention is advantageous in that the sensing device 2, instead of being equipped with components of high power consumption and great weight, such as a processor, a memory and a display unit, exploits a central processing unit of a smartphone (i.e., the primary computing device 1) to perform the computing operation, and that the result of the computing operation is presented to the user 5 on the screen (i.e., the display unit 11) of the smartphone, thereby reducing the weight and power consumption.

Moreover, as the sensing device 2 of the present invention is characterized by minimized weight and low power consumption, it is applicable not only to the aforesaid wristband but also to a heart stent with sensing capability that detects a width of a cardiac blood vessel of a user with a sensing unit 22 thereof. Alternatively, the sensing device 2 is applicable to a contact lens with sensing capability that detects the blood pressure at the user's ocular capillaries with a sensing unit 22 thereof.

Referring to FIG. 3, there is shown a block diagram illustrating the function of a separate computing system according to the second embodiment of the present invention. FIG. 3 is different from FIG. 1 in that the sensing device 2 has a first wireless communication unit 24 for receiving and transmitting wireless signals, and that the primary computing device 1 has a second wireless communication unit 16 for receiving and transmitting wireless signals. In the second embodiment, the primary computing device 1 and the sensing device 2 communicate with each other by one of WiFi communication, NFC communication, RFID communication, Bluetooth communication, Zigbee communication, and infrared communication. In other words, unlike the signal transmission unit 21 and the signal receiving unit 14 of the first embodiment, the first wireless communication unit 24 and the second wireless communication unit 16 of the second embodiment are capable of two-way (receiving-and-transmitting) wireless communication. Moreover, in the second embodiment, the primary computing device 1 further has a control interface unit 17. The control interface unit 17 provides a physiological information reading interface for making available the corresponding information according to the user's click selection. For instance, the user can make enquiries, via the physiological information reading interface, as to the fluctuations in body temperature over the past week or the average pulse over the past hour.

Referring to FIG. 4, there is shown a flow chart illustrating the operation of the separate computing system according to the second embodiment of the present invention. As shown in FIG. 4, steps S41˜S42 are implemented on the primary computing device 1, and steps S43˜S44 are implemented on the sensing device 2. For the sake of better understanding of the present invention, the primary computing device 1 and the sensing device 2, like those disclosed in the first embodiment, are exemplified by a smartphone and a wristband capable of sensing physiological information, respectively. Similarly, the second embodiment is illustrative, rather than restrictive, of the scope of the present invention. The flow chart in FIG. 4 omits similar operation processes depicted in FIG. 2, such as the regular transmission of physiological information relating to the sensed blood pressure, pulse, calories, body temperature, etc., to the primary computing device 1 by the sensing device 2.

Referring to step S41, the user enters a sensing device setting instruction via a touchscreen or a physical key (i.e., the control interface unit) of the smartphone (i.e., the primary computing device 1). For instance, the user clicks on the touchscreen to set the current physiological information to be detected as the pulse-related information and set the detection interval to be 10 minutes. In step S42, the smartphone transmits, via the second wireless communication unit 16, an uncoded wireless setting signal based on the sensing device setting instruction, and the wireless setting signal contains the sensing device setting instruction which has just been entered by the user.

In step S43, the first wireless communication unit 24 of the sensing device 2 (i.e., the wristband) receives the wireless setting signal. In step S44, the sensing device changes the value of a register thereof according to the wireless setting signal such that it detects a subject's pulse once every 10 minutes. Hence, the primary computing device 1 can not only display the data sensed by the sensing device 2 but also allow the user to directly and conveniently manipulate the measurement settings of the sensing device 2.

Referring to FIG. 5, there is shown a block diagram illustrating the function of a separate computing system according to the third embodiment of the present invention. The embodiment illustrated in FIG. 5 is different from the embodiments illustrated in FIGS. 1 and 3 in that the primary computing device 1 is capable of synchronously controlling multiple sensing devices (exemplified by a first sensing device 3 and a second sensing device 4) via the second wireless communication unit 16, and that the primary computing device 1 further comprises an identity authentication unit 18 configured to perform an identity authentication procedure on the first sensing device 3 and the second sensing device 4. In practice, the identity authentication unit 18 performs the identity authentication procedure according to the hardware IDs or media access control addresses (also known as MAC addresses) of the first sensing device 3 and the second sensing device 4.

Referring to FIG. 6, there is shown a flow chart illustrating the operation of the separate computing system according to the third embodiment of the present invention. As shown in FIG. 6, steps S61 and S62 are implemented on the first sensing device 3, steps S63 and S64 are implemented on the second sensing device 4, and steps S65˜S67 are implemented on the primary computing device 1. For the sake of better understand of the present invention, the primary computing device 1 is exemplified by a smartphone, the first sensing device 3 is exemplified by a heart stent with sensing capability, and the second sensing device 4 is exemplified by a contact lens with sensing capability. Similarly, the third embodiment is illustrative, rather than restrictive, of the scope of the present invention.

Referring to step S61, a heart stent (i.e., the first sensing device 3) undergoes the identity authentication procedure performed by the smartphone (i.e., the primary computing device 1) via, a first sensing communication unit 31. In step

S63, the contact lens (i.e., the second sensing device 4) undergoes the identity authentication procedure performed by the smartphone via a second sensing communication unit 41. In step S65, the wireless authentication signals from the heart stent and the contact lens, after being received by the smartphone, are delivered to the identity authentication unit 18 that performs the identity authentication procedure on the sensing devices. In steps S62 and S64, the heart stent starts to sense the user's physiological information (e.g. a width of a cardiac blood vessel), and the contact lens also starts to sense the user's physiological information (e.g. the blood pressure at ocular capillaries) after successful identity authentication, and then the sensed physiological information is transmitted to the smartphone. Moreover, it is preferable that the heart stent and/or the contact lens are/is configured to transmit, via, the first sensing communication unit 31 or the second sensing communication unit 41, wireless signals to the smartphone only when the sensed physiological information exceeds a critical value (for example, when the blood pressure exceeds 140 mmHg) so as to reduce the power consumption.

Referring to steps S66˜S67, the second wireless communication unit 16 of the smartphone receives and transmits the physiological information to the computing unit 12 to undergo the computing operation, and informs the user of a result of the computing operation via a screen (i.e., the display unit 11). Hence, the user knows the width of a cardiac blood vessel and blood pressure in a real-time manner. In other words, the user can instantly obtain information measured by multiple sensing devices.

Moreover, according to the conception of the present invention, another application involves the combination of a sensing device and a warning device. The sensing device comprises a power supply unit, a sensing unit, and a first wireless communication unit. The power supply unit is configured to electrically connect and supply power to the sensing unit and the first wireless communication unit. The sensing unit is configured to sense the user's physiological information and to transmit externally a warning message via the first wireless communication unit when the sensed physiological information exceeds a standard value. A warning device comprises a warning unit and a second wireless communication unit. After the second wireless communication unit has received the warning message, the warning unit performs a warning operation.

For instance, the sensing device is an electronic sphygmomanometer equipped with a short-range wireless communication unit and embedded in a garment. The sensing device transmits, via the short-range wireless communication unit, a

warning message to a microcomputer (i.e., the warning device) regularly or when the sensed physiological information exceeds a standard value (for example, when the sensed blood pressure exceeds 140 mmHg). The microcomputer has a buzzer (i.e., the warning unit) and a second wireless communication unit. After the second wireless communication unit has received the warning message, the buzzer starts to sound to warn the user.

Preferably, the warning device further comprises a computing unit (e.g. a microprocessor) configured to perform the computing operation on the physiological information contained in the warning message, and performs various respective warning operations according to the result of the computing operation. For example, slow sounds are generated when the blood pressure falls within the range of 140-160 mmHg, and short interval sounds are generated when the blood pressure exceeds 160 mmHg. It is preferable that the warning device is a pocket-sized computer or a microcomputer, and that the warning unit is selected from one of an audio device, a display device, and a vibration device.

In conclusion, a separate computing system of the present invention enables complex calculation operations and display to be performed on a smartphone via wireless transmission, and thus a sensing device, such as a wristband, a contact lens, or a heart stent, requires either no processor at all or only a simple microprocessor for facilitating the display of content. Therefore, the sensing device not only has electronic sensing capability but also fulfills the goals of minimized weight and low power consumption.

The preferred embodiments described above are exemplary and are not intended to limit the scope of the present invention. Hence, any equivalent modification or variation made to the aforesaid embodiments without departing from the spirit and scope of the present invention shall fall within the scope of the appended claims.
