First Claim
Patent Images
1. A device for determining impedance of depression, comprising:
- a sensor including a plurality of conductive stripes constituting a plurality of intersecting regions, wherein a pair of depressed conductive stripes intersected in an intersecting region form a contact point due to electrical contact so as to define a depressed intersecting region;
a driver for providing a high potential and a low potential;
a detector for detecting a signal of at least one conductive stripe;
a selector for operatively coupling the conductive stripes with the driver and the detector; and
a controller for controlling the driver, the detector and the selector to determine a contact impedance, wherein the contact impedance of each depressed intersecting region is determined based on the potentials at the contact point of one and the other of the pair of conductive stripes or the position of the contact point.

Abstract
A method and the device for position detection are disclosed. The device comprises a plurality of strips intersecting each other to form a plurality of intersecting regions. A pair of depressed strips intersecting on an intersecting region contact to each other on a contact point to form a depressed intersecting region, wherein the contact impedance of the contact point is determined according to the position of the contact point and the voltages on the contact point of one and the other of the pair depressed strips.
