  • Patent number: 8144453
    Abstract: A suspension system for a differential-pressure touch sensitive panel suspended over force sensors, for use in either fixed or mobile devices such as point of sales terminals, kiosks, laptops, monitors, PDAs, cell phones, UMPCs and more. In one embodiment, each side of the lens is encircled and supported by a looped string, monofilament or flexible wire, which is then looped around the back cover or base plate, forming a figure-8. The figure 8-loops bring the lens into a fixed state in the xy-plane without the addition of any friction causing physical contact. Other alternative implementations include continuous suspensions, bender suspensions and 3-dimensional force suspensions. Moreover, the present invention proposes the use of a flexible padding under the force sensors to allow the sensors to be slightly preloaded, which reduces the dependency on extremely tight mechanical tolerances.
