A radio frequency energy-harvesting apparatus is applied to a radio frequency energy-transmitting apparatus with a location detection function. The radio frequency energy-harvesting apparatus includes a direct current signal receiving-processing unit, a rectification and harmonic generation unit, and a radar wave receiving-transmitting unit. The rectification and harmonic generation unit is electrically connected to the direct current signal receiving-processing unit. The radar wave receiving-transmitting unit is electrically connected to the rectification and harmonic generation unit. The radio frequency energy-transmitting apparatus transmits a radar wave scanning to a space; after the radar wave receiving-transmitting unit receives the radar wave, according to the radar wave, the radar wave receiving-transmitting unit generates an alternating current signal; the radar wave receiving-transmitting unit transmits the alternating current signal to the rectification and harmonic generation unit; the rectification and harmonic generation unit generates a radar reflection harmonic wave and a direct current signal.

A system of recognizing identity of object and method of automatically recognizing identity of object are provided. The method is to shoot a monitoring region for obtaining a monitoring image, recognize an object image in the monitoring image, scan the monitoring region for retrieving each identity data of each wireless badge, determines each image position of each object image in the monitor region, determine each badge position of each wireless badge in the monitor region, and link the object image and the identity data together when the positions match with each other. The system can pair the object image with the identity data instantly, determine whether the object is unregistered, and effectively save the time and human resources required by artificially pairing the object images with the identity data.

A wireless communication system and method is provided. The wireless communication system includes a wireless transceiver device and a processing device. The processing device includes a direction control module, a power adjusting module and a boundary setting module. The direction control module controls the scanning direction and generates a point direction information record according to each reference position respectively. The power adjusting module adjusts the transmitting power and generates a point power information record according to each reference position and the corresponding point direction information record respectively. The boundary setting module generates a boundary information record. The processing device controls the transmitting direction and the transmitting power according to the point direction information record(s), the point power information record(s) and the boundary information record, so as to limit a transmission of the wireless signal within a specific area.
