Abstract: A position tracking system and a method thereof are provided. In the system, a power transmitting unit (PTU) provides power to a power receiving unit (PRU). The PRU chooses one of the PTUs adaptively to receive power, and broadcasts a broadcast information via a corresponding Bluetooth link. Three PTUs receive the broadcast information to obtain three pieces of position information respectively corresponding to the PRU respectively, and a position of the PRU is determined based on the position information of the three PTUs. Accordingly, positioning is implemented in the wireless charging technique by modifying software design.

Abstract: A wearable electronic device and an emergency method thereof are provided. The wearable electronic device includes a host and a strap. The host senses physiological information of a user by using a sensor. When the physiological information is determined as being abnormal, the host sends an enabling signal to the strap by a transmitting coil to enable the strap. After the strap is enabled, a warning light module displays a warning message based on the enabling signal.

Abstract: A wireless communication system for transmitting energy in ultrasonic waves, a host device, and a mobile device are provided. The wireless communication system includes at least one host device and at least one mobile device. The host device each includes an ultrasonic energy transmitter and a wireless communication receiver. The host device transmits an energy signal in ultrasonic waves through the ultrasonic energy transmitter. The mobile device each includes an ultrasonic energy receiver and a wireless communication transmitter. The mobile device receives the energy signal in ultrasonic waves through the ultrasonic energy receiver and drives the wireless communication transmitter through the energy signal to transmit a communication signal to a field, such that the host device located in the field receives the communication signal.

Abstract: A battery-free smart key with infrared system (IR) comprises a receiving coil, a side controller, and an infrared data association (IRDA) communication transmitter (TX) module. The receiving coil is able to receive electromagnetic waves with a wireless power and a certification data transmitted from an outside system. The side controller is used for processing the certification data and distributing the wireless power transmitted from the receiving coil. The IRDA communication TX module is coupled to the side controller and is able to transmit an IRDA communication signal with at least one certain user information. When the security entry system receives the correct IRDA communication signal, a door or an entry system can be unlocked. A car entry with IR system combined therewith is also disclosed.
