ABSTRACT:
The invention generally relates to a method for muting an alerting portable device such as a ringing cell phone or alarming PDA. Specifically where muting is activated in a means not requiring direct contact with the keys of the device. The indirect contact such as a hand pat or smack is detected within the device by a sensor such as a microphone or accelerometer. Control circuitry detects active indirect contact and then mutes the alert, and or does some other programmable operation.
