SIGNAL STABILIZATION IN A DIELECTRIC SENSOR ASSEMBLY
First Claim
Patent Images
1. A non-resistive contact sensor assembly, comprising:
- an electric field sensor device, including a dielectric component for receiving an electrical signal from an object of interest and an A/D converter for converting the electrical signal received from the object of interest to a digitized signal; and
circuitry interconnecting the dielectric component and the A/D converter and including a layer, directly below the dielectric component, that is substantially entirely ground fill.
