초록

A system and method for measuring the position of at least one field producing element (e.g., a magnet) without a direct electrical or physical connection between the field producing element and one or more sensors. In one embodiment, the output from an array of sensors (e.g., Hall Effect sensors) is curve fit using an algorithm having a characteristic bell curve (e.g., curve fit tracking algorithm, center of gravity algorithm, etc.) to determine at least one of an absolute or relative position associated with the field producing element and/or a proper...

청구항

What is claimed is: 1. A through wall position sensor system comprising: at least one field producing element separated by a wall from an array of sensors, wherein the array of sensors detects a property associated with the at least one field producing element and outputs a corresponding output signal indicative of the property associated with the at least one field producing element; and a processor communicatively coupled to the array of sensors for processing the output signal from one or more sensors, wherein the processor utilizes a tracking curve ...
