Signaling device
First Claim
1. A signaling device for use with a personal monitoring system that detects the location of a person wearing the signaling device, the signaling device includinga housing,a control circuit supported by the housing, andan oscillator circuit supported by the housing and configured to transmit a signal to the personal monitoring system, the oscillator circuit including means for tuning the frequency of the signal, the tuning means includes at least one RLC component that is disabled from impacting the frequency of the signal.

Abstract
A signaling device is disclosed that transmits a signal to a personal monitoring system. The signaling device may include an array of RLC components that determine the frequency of the signaling device. The frequency may be tuned by adding or removing RLC components from impacting the frequency. The signaling device may also include a wake-up mechanism for activating the signaling device for normal use and a signal indicating that a predetermined useful life is about to end.
