Patent number: 11928290Abstract: A scanning operation is performed to measure a first capacitance of a first sensor arrangement located proximate a capacitive sensor that corresponds to a function of a device. In response to the first capacitance not exceeding a first threshold, the scanning operation measures a second capacitance of the capacitive sensor to create an output used to control the function of the device. In response to the first capacitance exceeding the first threshold, operation of the scanning operation is modified to skip measuring of the second capacitance or to refrain from transmitting the output to a host of the device for controlling the function.Type: GrantFiled: April 3, 2023Date of Patent: March 12, 2024Assignee: Cypress Semiconductor CorporationInventors: Troy Gentry, David Durlin
