Abstract: A keyswitch-integrated pointing assembly in which a plurality of substantially planar force sensing elements are disposed on a planar surface adjacent a keyswitch on a keyboard. The keyswitch includes a plunger which extends downwardly from a key cap for actuating a switch at the lower end of vertical key cap travel. The key cap engages an indexing surface when fully depressed which transmits force applied to the key cap to the force sensing elements. The force sensing elements are sandwiched between a pair of opposing plates thereby biasing the elements into a substantially linear operating region when no force is applied to the key cap.

Abstract: Housing/mounting apparatus for a data gathering system inserted into a checkout counter and including a weighing scale and an optical scanner supported thereon for scanning bar code labels and defining an upper weighing surface of the scale comprises a base supported within the checkout counter for supporting the data gathering system with the scale being secured to the base. A perimeter enclosure is secured to the base and houses the optical scanner. The scale includes a spider load receiving plate supported within the perimeter enclosure through an aperture in its floor. Locator pins and corresponding holes stably position the optical scanner on the scale load receiving plate and the optical scanner thus positioned is sized such that clearance gaps required for proper operation of the weighing scale are defined between the optical scanner and the perimeter enclosure. Leveling and fastener or clamping devices are incorporated into the base to facilitate installation and maintenance of the system.
