Embodiment Construction

[0039] The present invention is best understood when described in connection with a position detection system, such as a digitizer. U.S. Patent No. 6,690,156 and U.S. Patent Application Serial No. 10 / 649,708, entitled "Transparent Digitizer," describe devices capable of detecting various physical objects (such as pens) located on top of flat screen displays. Position detection device, the disclosure of said patent is hereby incorporated by reference. One of the preferred embodiments in the two publications describes a sensor consisting of a transparent foil comprising a matrix of vertical and horizontal conductors. Optionally, the electromagnetic pen is used to use and control at least one of the following: tablet personal computer (tablet "PC"), pen-enabled laptop PC, personal data assistant ("PDA") or Any handheld device. The pen includes an oscillating circuit powered by a peripheral coil surrounding the sensor. The precise position of the pen is determined by processing...

Abstract

A position detection system, comprising: at least one pointer, comprising: a wave generating oscillator section; a power supply section powering the oscillator section, and an energy pick-up circuit which supplies energy to the power supply section from an excitation signal received by the circuit; and, a detector, comprising a sensor operative to detect the position of the at least one pointer from a wave generated by the wave generating section.

Description

[0001] related application [0002] This application claims the benefit under 119(e) of U.S. Provisional Patent Application 60 / 631,862, filed December 1, 2004, and U.S. Provisional Patent Application 60 / 657,439, filed March 2, 2005, both applications The title is "Electromagnetic Stylus for a Digitizer System". The disclosures of both applications are hereby incorporated by reference. technical field [0003] The present application relates to apparatus and methods for using and controlling a position detection system. Background technique [0004] Electromagnetic pens are well known in the field of use and control of digitizer systems. For example, US Patent No. 4,878,553, the disclosure of which is incorporated herein by reference, describes an electromagnetic pen used in conjunction with a flat panel sensor. The sensor includes a set of loop coils for transmitting electromagnetic waves to a resonant circuit inside the pen, mainly by magnetic coupling. When excited by ...
