A deformable switch keyboard assembly with a flexible unitary top member, a compressible intermediate switch assembly layer and a bottom member providing mechanical support for the intermediate assembly and mechanical isolation for the switching function.The top member has a plurality of switch site defining regions extending in a first direction and located in a predetermined array to define the keyboard. The intermediate switch assembly has a plurality of switch sites each underlying a different one of the top member projections. The bottom member has first and second sets of projections extending toward the top member, each of the first set of projections underlying a different one of the switch sites and providing a compression contact beneath the intermediate switch assembly when the corresponding top member region is actuated to advance in the first direction. Each of the second set of projections is located intermediate different adjacent ones of the switch sites and is longer than any of the first set of projections in order to provide mechanical isolation between an actuated switch site and the remainder of the switch sites.       Recently Added Patents Systems, methods, and computer program products for estimating crowd sizes using information collected from mobile devices in a wireless communications network Adjustable mounting device for exercise equipment Temporal document trainer and method Method, system, router and apparatus for implementing switching between layer-2 multicast route tracing and layer-3 multicast route tracing Composition and method for inhibition of microorganisms Writing instrument Storage of a document using multiple representations   Randomly Featured Patents Endoprosthesis for the knee joint System and program product for throttling events in an information technology system Composition for forming anti-reflective coating for use in lithography Radial lip shaft seal Stemmed wine glass or similar article Efficient implementations of kernel computations Semiconductor device having an increased area of one of the opposing electrode parts for preventing generation of unconnected positions the electrodes on the bonded wafers Drive system for grinding mills Wireless base station device, terminal, and wireless communication method Air scoop lip warmer de-icing system © 2006-2008 PatentGenius.
