Latest Patents
One of Chenghao Fan's latest patents is a method and apparatus for noise control in ultrasonic sensors. This innovation involves an adjustable voltage regulator controlled by a microcontroller. It applies a controlled amplitude voltage in the range of 5 to 9 VDC to the sensor transmitter, allowing for the adjustment of the output amplitude. This adjustable amplitude transmitter enables an occupancy sensor to modify its total output energy, thereby reducing environmental noise-induced false triggering. By lowering the total ultrasonic energy in the monitored space, the sensitivity of the receiver to inappropriate activations is decreased. Additionally, reducing the input power to the transmitter lowers the total internal system noise, resulting in an improved signal-to-noise ratio in the receiver.
