Patent number: 9448053Abstract: A microwave motion sensor including a transmitting device, a signal processing device, a signal processing device, and a path switching device is disclosed. The transmitting device transmits a microwave signal to a space under detection. The receiving device receives a reflected microwave signal reflected from the space under detection. The signal processing device processes the reflected microwave signal received by the receiving device to judge whether there is a disturbance in the space under detection, wherein the signal processing device generates the microwave signal. The path switching device is coupled to the signal processing device and the transmitting device and results in different phase shifts to a plurality of transmission paths travelled by the microwave signal.Type: GrantFiled: April 19, 2013Date of Patent: September 20, 2016Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Je-Kuan Jau, Ping-Hsun Wu

Patent number: 8698636Abstract: A wireless detection apparatus includes an antenna, a voltage control oscillator, and a processing unit. The antenna receives a first wireless signal and generates an electrical signal according to the first wireless signal. The first wireless signal is generated by reflecting a second wireless signal from an object under test. The voltage control oscillator is coupled to the antenna to generate an oscillating signal under an interference of the electrical signal. The oscillating signal varies with variation of the electrical signal. The processing unit is coupled to the voltage control oscillator to evaluate a parameter of the object under test according to the variation of the oscillating signal.Type: GrantFiled: September 20, 2010Date of Patent: April 15, 2014Assignees: Industrial Technology Research Institute, National Sun Yat-sen UniversityInventors: Tzyy-Sheng Horng, Fu-Kang Wang, Chieh-Hsun Hsiao, Je-Kuan Jau

Patent number: 8665098Abstract: A non-contact motion detection apparatus includes at least one reception antenna, at least one transmission antenna, a voltage-controlled oscillator (VCO) and a phase lock loop (PLL). The at least one reception antenna receives a first wireless radio frequency (RF) signal. The at least one transmission antenna transmits a second wireless RF signal to an object which reflects the second wireless RF signal into the first wireless RF signal. The VCO outputs an oscillation signal to the at least one transmission antenna. The first wireless RF signal received by the at least one reception antenna is injected to the VCO. The PLL generates a control voltage to the VCO according to the oscillation signal from the VCO and a reference frequency. Controlled by the control voltage, which represents a motion information of the object, the oscillation signal of the VCO is locked to the reference frequency.Type: GrantFiled: May 31, 2012Date of Patent: March 4, 2014Assignee: Industrial Technology Research InstituteInventors: Je-Kuan Jau, Ping-Hsun Wu

Publication number: 20070018718Abstract: The microwave transmitter of the present invention can perform two-terminal dynamic modulation with respect to the voltage supply terminal and the RF input terminal of a RF power amplifier. The microwave transmitter of the present invention comprises a first modulator and a second modulator. The first modulator uses the baseband digital delta-sigma modulation technique to process the envelope signal and outputs this signal to the voltage supply terminal of the RF power amplifier as a supply voltage. The second modulator uses the baseband digital pre-distortion technique to process the IQ-modulated carrier and outputs this signal to the RF input terminal of the RF power amplifier as a RF input signal. Thereby, the RF power amplifier can highly efficiently reconstruct the power-amplified RF modulated carrier without distortion at the RF output terminal.Type: ApplicationFiled: June 19, 2006Publication date: January 25, 2007Applicants: National Sun Yat-sen University, Industrial Technology Research InstituteInventors: Tzyy-Sheng Horng, Yuan Chen, Je-Kuan Jau, Jian-Yu Li, Chang-Ming Lai
