Abstract

Conventional bezel switches rely on mechanical contacts. This paper describes a novel technology using high frequency trapped mechanical vibrations to sense switch action with no moving parts. This technology provides robust switch activation and a high level of environmental immunity (both electrical and mechanical). The signal processing scheme recognizes if a switch has failed or is about to fail, and can move switch functions in a pre-determined manner to other switch positions on the bezel. The result is a "smart bezel" with not only higher reliability over mechanical switches, but with the ability to greatly improve overall system reliability as well as support on-board maintenance by five times, reduce the maintenance costs by 50% and repair costs by 90%, thereby providing substantial savings to the Navy in T-45 multi-functional display Life Cycle Costs. The resulting system architecture as explained in this paper is used in conjunction with a "smart display" to fully realize the advantages of this technology. This new bezel technology has recently been flight qualified in a military aircraft.
