Proximity switch assembly and method of sensing user input based on signal rate of change
First Claim
1. A method of operating a proximity switch comprising:
- detecting a first signal associated with a first proximity switch for performing a first function and a second signal associated with a separate neighboring second proximity switch for performing a second function;
determining with a controller a first rate of change of the first signal and a second rate of change of the second signal; and
performing the first function of the first switch based on both the first rate of change and the second rate of change.

Abstract
A proximity switch assembly and method for detecting activation of a proximity switch assembly is provided. The assembly includes a plurality of proximity switches each having a proximity sensor providing a sense activation field and control circuitry processing the activation field of each proximity switch to sense activation. The assembly and method detects a signal associated with each proximity switch, determines a rate of change of the signal associated with the first switch and a rate of change of the signal associated with a neighboring second switch and determines whether to activate the first switch based on at least one of the first rate of signal change and second rate of signal change.
