Patent number: 11635840Abstract: In a method for determining touch applied to an electronic device, ultrasonic signals are emitted from an ultrasonic sensor. A plurality of reflected ultrasonic signals from a finger interacting with the ultrasonic sensor is captured. A first data based at least in part on a first reflected ultrasonic signal of the plurality of reflected ultrasonic signals is compared with a second data based at least in part on a second reflected ultrasonic signal of the plurality of reflected ultrasonic signals. A signal change due to a change in a feature of the finger during a touch interaction with the ultrasonic sensor is determined based on differences between the first data and the second data. A touch applied by the finger to the electronic device is determined based at least in part on the signal change due to the change in the feature of the finger.Type: GrantFiled: June 28, 2021Date of Patent: April 25, 2023Assignee: InvenSense, Inc.Inventors: Eitan Medina, Behrooz Abdi, Sam Massih, Romain Fayolle, Hao-Yen Tang
