Title: Mark J Phillips: Innovator in Coordinate Determining Devices

Introduction

Mark J Phillips is a notable inventor based in Wayland, MA (US). He has made significant contributions to the field of technology, particularly in the development of coordinate determining devices. His innovative approach has led to the creation of a unique digitizing tablet that enhances the accuracy of position detection.

Latest Patents

Phillips holds a patent for a "Coordinate determining device using spatial filters." This invention features a digitizing tablet that utilizes two sets of circuitous conductive lines forming grids, each connected to a surrounding conductive loop. The outputs are measured from the conductive loop as a multiplexor sequentially grounds the grids one at a time. The outputs are processed through linear spatial filters to produce intermediate signals, which are then combined to generate raw position signals for a position-indicating coil located over the work surface. Notably, separate sets of linear spatial filters can produce two raw position signals that respond differently to tilt, allowing for the creation of a true position signal that is insensitive to tilt.
