Abstract: A wireless communication system using mimicked near field communication is disposed in a peripheral application device and configured to be connected with a mobile device. The system includes a wireless communication module configured to send a control command, and an RF switching circuit configured to be switched to a low or normal power mode according to the control command. Under the low power mode, a signal attenuation unit of the RF switching circuit attenuates a frequency of a transmission signal emitted from the wireless communication module to generate an output signal. Under the normal power mode, the signal attenuation unit maintains the frequency of the transmission signal. The signal frequency is allowed to be attenuated during an authentication phase to thereby achieve near field communication, and an original wireless transmission mechanism is allowed to be used after authentication is completed so as to perform operation of the peripheral application device.

Abstract: An object location guiding device and an operation method thereof are provided. The object location guiding device includes a processor, a controller and a guiding element array. Guiding elements of the guiding element array are disposed at different positions in a field so as to point to storage positions of different objects in the field. The processor converts the object data on an object list into storage-position information. The controller receives the storage-position information from the processor, converts the storage-position information into a first axis position code and a second axis position code, and drives the guiding element array by using the first axis position code and the second axis position code, so as to allow at least one corresponding guiding element of the guiding elements to point to a storage position of a corresponding object in the field.

Abstract: A wireless sensing system includes a sensing device, a transmission device, and a micro-processing device. The sensing device senses a physical quantity or a chemical quantity of peripheral environment and generates a sensing signal.

After the system is initialized, the micro-processing device and the transmission device are in a sleep state. When the sensing signal is larger than a threshold value, the sensing device wakes the micro-processing device and the transmission device up.
