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.
