The first antenna receives a first signal generated by a second signal reflected by a target object, so as to output the first signal to the phase detector or the voltage-controlled oscillator. The voltage-controlled oscillator receives first signal or the second signal and receives a frequency adjustment signal, so as to generate an oscillating signal according to the frequency adjustment signal and the one of the first signal and the second signal. The phase detector receives the oscillating signal and another one of the first signal and the second signal, and generates a first phase output signal and a second phase output signal. The signal processing unit estimates motion parameters of the target object according to the first and the second phase output signal. | 06-30-2016 |

20160377704 | HUMAN POSTURE FEATURE EXTRACTION IN PERSONAL EMERGENCY RESPONSE SYSTEMS AND METHODS - A non-wearable Personal Emergency Response System (PERS) architecture is provided, implementing RF interferometry using synthetic aperture antenna arrays to derive ultra-wideband echo signals which are analyzed and then processed by a two-stage human state classifier and abnormal states pattern recognition. Systems and methods transmit ultra-wide band radio frequency signals at, and receive echo signals from, the environment, process the received echo signals to derive a spatial distribution of echo sources in the environment using spatial parameters of the at least one transmitting and/or receiving antennas, and estimate postures human(s) in the environment by analyzing the spatial distribution with respect to echo intensity. The antennas may be arranged in several linear baselines, implement virtual displacements, and may be set into multiple communicating sub-arrays. The decision process is carried out based on the instantaneous human state (local decision) followed by abnormal states patterns recognition (global decision). | 12-29-2016 |
