Title: L Stephen Pilcher: Innovator in Optical Pointing Devices
Introduction
L Stephen Pilcher is an accomplished inventor based in N. Ferrisburg, VT (US). He has made significant contributions to the field of optical pointing devices, showcasing his innovative spirit and technical expertise.
Latest Patents
Pilcher holds a patent for a "Pointing device having improved automatic gain control and information." This invention features an improved optical pointing device that utilizes a moveable unit equipped with a voltage-to-frequency converter (VFC). The VFC emits pulses with separation proportional to the angular rotative and/or translational position of the moveable unit. These pulses are applied to an LED of the moveable unit. A microcomputer in a base unit measures the separation of the pulses received by a photodetector to determine the components of the angular rotative and/or translational position of the moveable unit. Additionally, automatic gain control circuitry is located in the moveable unit, eliminating the need for two-way communication to achieve consistent operation in a prescribed space. Pilcher's innovative approach enhances the functionality and reliability of optical pointing devices.
