Latest Patents
One of his latest patents is for an adjustable keyboard for a personal computer. This invention features a screened pattern that creates gaps around the keyboard membrane spacer hole. The design includes first and second membranes carrying contacts located on opposing faces, separated by a third or spacer membrane with holes. This configuration allows a circuit to be completed between the contacts when force is applied to the first membrane. The arrangement of the membranes defines substantially enclosed switch regions, and they are mechanically held together without adhesives in areas other than the switch regions. The inclusion of spacer elements between the spacer membrane and one of the first and second membranes forms air pockets, allowing air to flow as the first membrane is depressed and released. This design reduces pressure buildup and variations in the switch region, enhancing the speed at which contacts open and minimizing contact bounce.
