SYSTEM AND METHOD TO DETECT A PRESENCE OF AN OBJECT RELATIVE TO A SUPPORT
First Claim
Patent Images
1. A system to detect a presence of an object on a support, the system comprising:
- an antenna circuit embedded in the support; and
a tuner controller electrically connected to the antenna circuit, wherein the tuner controller is operable to measure a change in an impedance of the antenna circuit 130 in response to a test signal through the antenna circuit for comparison to a threshold associated with a change in presence of the object on the support, and based on comparison, is operable to generate an output signal indicative of the change in presence of the object on the support.

Abstract
A system and method to detect a presence of an object relative to a support is provided. The system can generally include an antenna circuit embedded in the support; and a tuner controller electrically connected to the antenna circuit. The tuner controller can be operable to measure a change in an impedance of the antenna circuit associated with a change in presence of the object to and from the support, and based on this comparison, can generate an output signal indicative of the change in presence of the object on the support.
