PROXIMITY SWITCH ASSEMBY WITH SIGNAL DRIFT REJECTION AND METHOD |
摘要 |
A proximity switch assembly and method for detecting activation of a proximity switch assembly is provided. The method includes steps of generating activation fields with a plurality of proximity sensors associated with a plurality of proximity switches, monitoring amplitude of a signal generated in response to each of the activation fields, subtracting the smallest signal from each of the other signals, and determining activation of one of the plurality of proximity switches based on the subtracted signals. A proximity sensor assembly and method of suppressing noise for a plurality of proximity sensors is also provided, which includes subtracting the smallest signal from each of other signals associated with a plurality of proximity sensors and determining activation of one of the plurality of proximity sensors based on the subtracted signals. |

1. A method of activating a proximity switch assembly comprising:
generating activation fields with a plurality of proximity sensors associated with a plurality of proximity switches; monitoring amplitude of a signal generated in response to each of the activation fields; subtracting the smallest signal from each of the other signals; and determining activation of one of the plurality of proximity switches based on the subtracted signals. |
