A portable electronic device to be used as a keyless device of a vehicle includes a controlling circuit which includes a physiological feature detection module and a processing circuit. The physiological feature detection module is used for detecting a physiological feature of a person. The processing circuit is coupled to the physiological feature detection module and used for determining whether the person is an authorized user of the vehicle according to the detected physiological feature of the person, and for opening a car door of the vehicle or starting the vehicle when the person is identified by the processing circuit as the authorized user.

Scheme for setting/using electronic device as keyless device of vehicle and adjusting devices in the vehicle

A multiple detection system is applied to a vehicle and includes a contact-type detection module adapted to generate a contact-type detection datum, a contactless-type detection module adapted to generate a contactless-type detection datum, and an operation processor electrically connected with the contact-type detection module and the contactless-type detection module in a wire manner or in a wireless manner. The operation processor sets at least one of the contact-type detection datum and the contactless-type detection datum according to an environmental status of the vehicle to be a main detection result of the multiple detection system, and further sets the other detection datum to be an auxiliary detection result of the multiple detection system, for acquiring a passenger feature inside the vehicle.

Multiple detection system

A game board device is provided for carrying and identifying game pieces that are divided into different piece types. The game board device includes a board, a plurality of optically identifying modules, and a processing module electrically coupled to the optically identifying modules. The optically identifying modules respectively correspond in position to detection regions of the board. Each of the optically identifying modules includes a light emitter that can emit light toward the corresponding detection region and a light receiver that can receive light reflected by the corresponding detection region. When any one of the detection regions is in an unoccupied mode, the corresponding optically identifying module can emit an unoccupied signal. When any one of the detection regions is in an occupied mode, the corresponding optically identifying module enables an identification signal that corresponds to the piece type of the corresponding game piece to be emitted therefrom.

Game board device

A wireless charging device and an operation method thereof are provided. The wireless charging device includes a charging module, at least one proximity sensor and a central controller. The wireless charging device senses a distance variation between the wireless charging device and an object using the proximity sensor and accordingly determines whether to turn on or turn off the charging module to achieve energy saving.

Wireless charging device and operation method thereof

A method of wireless communication locator station to be disposed at specific location includes: detecting rotation angle information of client-based portable device, carried or worn by user, according to specific wireless communication standard between wireless communication locator station and client-based portable device when client-based portable device is within signal range of wireless communication locator station; generating head pose direction estimation according to calculated rotation angle information; and when head pose direction estimation indicates that a user turns face towards wireless communication locator station, sending packet signal from wireless communication locator station to server-based portable device, successfully paired with and security-connected with client-based portable device, so that server-based portable device can transfer packet signal to client-based portable device after receiving packet signal.
