Latest Patents

Ke Sun holds a patent for a device that employs ultrasound signals to sense ambient temperature and relative humidity. The technology involves emitting an ultrasound signal using a speaker and measuring it with a microphone. The device can determine a signal component corresponding to a direct propagation path (DPP) between the speaker and the microphone. It calculates a first sound propagation property that represents the speed of the ultrasound signal along the DPP. Additionally, the device assesses second sound propagation properties across different frequency bands, which represent sound attenuation of the ultrasound signal along the DPP. Ultimately, it determines ambient temperature and relative humidity values using a regression model based on these sound propagation properties. This innovative approach enhances the accuracy of environmental sensing.
