The present invention relates to a portable device, and more particularly to a portable device with a thermal sensor.
Cellular communications systems typically include multiple base stations for communicating with mobile stations in various geographical transmission areas. Each base station provides an interface between the mobile station and a telecommunications network. Mobile telephone systems are in use or being developed in which the geographic coverage area of the system is divided into smaller separate cells, it communicates with the network via a fixed station located in the cell. Mobile telephones belonging to the system are free to travel from one cell to another. When a subscriber within the same system or within an external system wishes to call a mobile subscriber within this system, the network must have information on the actual location of the mobile telephone.
Recently, anti-theft unlocking problems of the portable device are increasingly valued by the market. The traditional password lock applied to the mobile phone can be easily cracked, and therefore the manufacturers develop different anti-theft methods one after another. The gradually mature biological feature recognition technology is highly thought of by the manufacturers and consumers. The common biological feature recognition technology employs a sensor to recognize biological features such as fingerprints, palm prints, shape of face, iris or DNA. The aforementioned methods have their advantages or disadvantages respectively. The fingerprint recognition is the most common one.

In one embodiment, the wireless communication connection between the portable device 100 and the remote server 200 may specifically employ the following connection methods: wireless communication technologies or specifications such as wireless communication network (3G/4G/5G), satellite communication network, Wi-Fi, 802.11x (x=a, b, g, n), Bluetooth low energy (BLE), long term evolution (LTE), Zigbee or infrared etc.
The memory 123 and 217 of the present invention may include ROM (read only memory), RAM (random access memory), nonvolatile flash memory, etc. The display 129 includes multi-touch panel such as resistive touch panel or capacitive touch panel, and so on.
As mentioned above, after the wireless communication module 109 (such as wireless communication network (3G/4G/5G) module) is coupled with the access point 151, the access point 151 is further connected with the wireless communication module of the remote server 200 through the communication network 161 or/and internet 171, and then the remote server 200 receives the data such as photographs or images transmitted from the wireless communication module 109. The transaction data of the mobile pay module may also be displayed on the display during the aforementioned transmission process.
As shown in
For remote authentication or transaction, the GPS (satellite positioning) unit 115 is utilized to acquire a position information corresponding to the portable device 100 to provide the geographical coordinates at which the user is located. The geographical coordinates cooperate with the stored map information to perform navigation or search specific coordinates. Subsequently, after the wireless communication module 111 (such as wireless communication network (3G/4G/5G) module) is coupled with the access point 151, the access point 151 is further connected with the wireless communication module of the server 200 through the communication network 161, internet 171, and then the server 200 receives the image data, the finger pulse waveform signals or the scatter diagram transmitted from the wireless communication module 111. The image data, the finger pulse waveform signals or the scatter diagram transmitted from the wireless communication module 111 are performed with biological feature recognition in the server 200 for the pay transaction authentication of the portable device 100, the transaction authentication of the unmanned store. The biological feature recognition mentioned above may also be implemented at the mobile phone end.
As mentioned above, the portable device 100 of the present invention may include a temperature sensor 107 coupled to the processing unit 101. In one embodiment, the temperature sensor 107 may include an infrared temperature sensor 107 to sense the body temperature of the user with the infrared temperature sensor 107. The temperature sensor 107 may include an active infrared temperature sensor or a passive infrared temperature sensor. The active infrared temperature sensor performs the sensing of the body temperature by actively emitting infrared light and receiving the infrared light reflected by the user while the passive infrared temperature sensor implements the sensing of the body temperature by receiving the infrared light emitted by the user. In one example, the temperature sensing procedures of the portable device 100 include the following steps. Firstly, the temperature setting unit 125 presets the temperature range according to the user's demand. For instance, the user can set the body temperature range to be 36□˜40□ according to his/her body condition. The purpose of the temperature sensor is to cooperate with the face recognition, the fingerprint recognition or the pupil recognition to assist in determining that the face or the biological feature signals are live user signals, not photographs or other digital images. That is to say, when the user activates the biological feature recognition, the processing unit 201 at least activates the biological feature recognition module 203 and the temperature sensor 208 to perform the biological feature recognition and the temperature detection at the same time, so as to ensure the accuracy of the identity recognition. The temperature sensor 107 can sense the body temperature of the user in real time to acquire the body temperature value of the user sensed by the temperature sensor 107. The temperature sensor 107 may be activated by for example general purpose input output (GPIO). The temperature comparing unit 113 determines whether the sensed body temperature value of the user is in the preset body temperature range or not. If yes, the authentication is completed or unlock succeeds. If not, the authentication or unlock fails. For instance, if the temperature comparing unit 113 determines that the obtained body temperature value of the user 37.2□ is in the preset body temperature range (36□˜40□) and the comparison of the recognized biological feature matches, authentication is completed or unlock succeeds.
When the processing unit 101 receives the measured temperature value from the temperature sensor 107, it is determined that whether the measured temperature value is within the possible range of the human body's temperature or not. If not, the functions of unlocking, paying authentication, and the transaction authentication are prohibited. If yes, the biological feature recognition is performed, for example the face image matches the temperate, the authentication will be approved. The temperature sensor 107 is utilized to sense the body temperature of the user. The temperature sensor 107 may be configured in the portable device 100. In one embodiment, the temperature sensor 107 may be configured outside of the portable device 100 to be directly connected with the portable device 100 via a connection wire. However, the mobile phone unlocking, pay authentication, and the transaction authentication of the unmanned store are performed by comparing the feature images of the identical feature of the user (such as face, eye) and sensing the temperature of the user at the same time.
The finger pulse detecting module 103 detects the pulse blood flow signal in the finger's capillary of the user who uses the portable device 100. The analog-to-digital converter 141 converts the pulse blood flow signal of the user, and the characteristic points are captured by the processing unit 101 and are compared with the preset characteristic points of the user in the heart rate recognition database 205 in the server 200 or the mobile phone. If the characteristic points of the user match the preset characteristic points of the user in the heart rate recognition database 205, the correct signals are output and the user is permitted to perform subsequent user authentication and transaction.
In another embodiment, the portable device 100 includes a gradient image sensing module 108 coupled to the processing unit 101 as shown in
Taken as an example, the gradient image sensing module 108 may be an infrared light camera module, which may have a pixel resolution of at least about 240 pixels×320 pixels, a thermal accuracy of 2 degrees Celsius or 2%, a thermal sensitivity smaller than about 0.1 degrees Celsius and an operational power requirement of about 25 Watt for the appliance of battery driving. The infrared light camera module may be remotely located with respect to one or more objects to be imaged, and the thermal image from the infrared light camera module may be analyzed by the thermal image analyzing module 118 of the portable device 100. The temperature gradient may then be displayed on the display by the thermal sensor and the body temperature of the use may be calculated by the processing unit 101.
In another embodiment, once the portable device 100 receives the infrared thermal image, the infrared thermal image may be transformed into the temperature data. A mathematical algorithm or formula may be applied to perform the transformation. The mathematical algorithm or formula employs the given emittance value to correlate the sensor data of the infrared light camera module in Watt with thermal value. The infrared thermal images may be processed, calculated and converted into the temperature data by the processing unit 101 of the infrared light camera module. As mentioned above, the pixel values in the infrared thermal images indicate the temperature at physical points in the space. Thus, the average value or the median of the temperature values of these pixels may be determined.
The wireless communication module 109 is compatible to wireless communication protocols and can process the data transmission of the wireless communication protocols. For instance, the wireless communication module 109 may be Bluetooth compatible module, Wi-Fi wireless transmission standard compatible module, 802.11x wireless transmission standard compatible module, or WiMAX (Worldwide Interoperability for Microwave Access) wireless transmission standard compatible module. The portable device 100 of the present invention can wirelessly transmit image signals to the server 200 simultaneously through the wireless communication module 109.
