Method And Device For Improved Accuracy Of Proximity And Touch Detection In Mobile Devices

Patent No. EP3694106 (titled "Method And Device For Improved Accuracy Of Proximity And Touch Detection In Mobile Devices") was filed by Semtech on Mar 2, 2015. The application was issued on Feb 22, 2023.

Patent Summary

A capacitive sensing controller for mobile devices that improves proximity detection accuracy by using a dedicated analog-to-digital converter to process sensor data from a first sensor input, while a second sensor input is used to detect the presence of a human body. The controller enables an immediate decrease in RF power output when a mobile device is moved within a predetermined distance of a human body, and an immediate increase in RF power output when the device is moved outside of that distance.
