Touch Sensor System
First Claim
1. A touch sensor assembly comprising:
- a housing;
a circuit board configured to be received at least partially in said housing;
at least one touch sensor coupled to said circuit board; and
a sensor cover configured to be received at least partially in said housing with said circuit board disposed between said housing and said sensor cover, said sensor cover comprising a graphical indicator of a touch area associated with said at least one touch sensor,said housing comprising a mating feature configured to mate with a corresponding feature on a rear surface of an housing cover to provide a substantially water tight cavity for enclosing said circuit board and said sensor cover between said housing and said housing cover.

Abstract
A touch sensor assembly. The touch sensor assembly may include a housing, at least one touch sensor and a sensor cover. The sensor cover may identify a touch area associated with each touch sensor. The housing may form a water tight cavity for the sensor cover and the touch sensor when coupled to an housing cover. A raised dome may be provided, e.g. on the sensor cover or another element, to provided tactile feed back. LEDs may be provided for illuminating the touch areas and/or sensing ambient light. A controller may control the illumination level of the LEDs in response to sensed ambient light. Adjacent key suppression algorithms are also provided.
