Title: Ultrasonic water-agnostic touch detection sensor
Inventor: KHAJEH EHSAN
IPC: G06F3/043
Filed: 2021-06-22
Abstract: Disclosed is an ultrasonic touch sensing system which uses both compressional and shear waves for touch and water detection. When no touch or water is present, less shear and compressional wave energy is absorbed, so that neither shear nor compressional wave reflections have significant amplitude decreases. When a finger is in contact with a sensing plate, both shear wave energy and compressional wave energy are absorbed, so both shear and compressional wave reflections have significant amplitude decreases. When water is in contact with the sensing plate, compressional wave energy is absorbed but little or no shear wave energy is absorbed, so while compressional wave reflections have significant amplitude decreases, shear wave reflections do not. From these amplitudes, a determination of whether no touch is present on the sensing plate, whether a touch is present on the sensing plate, or whether water is present on the sensing plate can be made.
