Patent ID: 11928290
Assignee: CYPRESS SEMICONDUCTOR CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 14:
15. A system, comprising:
a first capacitive sensor corresponding to a first function of a device;
a sensor arrangement proximate the first capacitive sensor, wherein the sensor arrangement comprises a plurality of proximity sensors electrically coupled together so that the plurality of proximity sensors are electrically equivalent, and wherein the plurality of proximity sensors are physically separate proximity sensors; and
a scanning circuit that implements a scanning operation to:
measure a first capacitance of the sensor arrangement;
in response to the first capacitance not exceeding a first threshold, measure a second capacitance of the first capacitive sensor to create a first output used to control the first function of the device; and
in response to the first capacitance exceeding the first threshold, skip measuring the second capacitance or refrain from transmitting the first output to a host of the device for controlling the first function.
