Appl. No.:

7/977134

Inventors:

James L. O'Callaghan - Salt Lake City UT

Assignee:

Cirque Corporation - Salt Lake City UT

International Classification:

H05K 714
G06F 116

US Classification:

361683

Abstract:

A device and a method for attaching a touch pad to a portable computer comprises a tray for holding the touch pad securely, a rail guide attachable to the underside of the computer, and a pair of rails, to which the tray is attached, slidably disposed in slots in the rail guide. The tray, and thus the touch pad, may slide to a location under the computer where it is not exposed or may slide from under the computer so that the touch pad is exposed. The tray may be pivoted so that the touch pad more directly faces the user. Support arms may be engaged between the tray and the rails to maintain the touch pad in the tilted position. Feet may be used to support the computer above a surface to furnish space for the attachment device. Cable guides may be provided as part of the rail guide and feet to guide the touch pad cable to the proper computer port and to relieve strain on the cable.

Abstract:

A simplified touch pad which detects a "touch" in a specific absolute positioning programmable zone or "enter/select" zone rather than requiring a "tap". The touch pad also has an audible feedback device built into the touch pad for immediate feedback and a touch sensitive surface comprising a relative cursor positioning zone. By simplifying a touch pad to include only basic functions, the touch pad is easier to operate, simpler to manufacture, and more amenable to use with graphical interface display systems typically using touch screens. The invention is preferably incorporated into a kiosk where simplified use is of great benefit. An embodiment of the invention includes an enclosure which completely seals the touch pad from external contamination making the touch pad waterproof and dust proof A cover plate also provides durability and added protection for the touch-sensitive surface of the touch pad.
