Patent ID: 8169332

Claim:
An integral force-sensitive touch-responsive input device comprising: A) an electronic display, B) a planar electronic assembly that supports said electronic display and includes a port for visual access to said electronic display, C) a first cover having a transparent portion and a peripherally extending conductive frame coincident with and substantially parallel to said electronic display, D) a second cover having an access port aligned with said first cover and depending edges that form a cavity for receiving said electronic display, said planar electronics assembly and said first cover, E) a capacitive sensing device at each of a plurality of positions about the periphery of said first cover and intermediate said first cover and said planar electronics assembly, each of said capacitive sensing devices including a discrete first electrode at each capacitive device position, said peripheral conductive frame constituting a second electrode that is common to at least two of said discrete first electrodes, F) a complaint structure proximate each discrete first electrode between said planar electronics assembly and said first cover that establish an initial spacing between said planar electronics assembly and said first cover whereby, during a touch on said first cover, the orientation of said first cover with respect to said planar electronics assembly depends upon the force and location of the touch, and G) a processor that controls the image on said electronic display and monitors the capacitance of each capacitive sensing device thereby to determine the force and location of a touch at any location on the first cover whereby said force-sensitive touch-responsive input device is an integral device.
