    摘要： A water-flow detector with an electronic time delay. There is a light-emitting diode and photo-transistor detector pair, a timer comprising an oscillator and a counter, and an alarm relay. The output of the photo-transistor is applied to the reset input of the counter, and the counter output is applied to the relay. The electronic assembly is positioned over the actuator arm of a paddle-type flow sensor assembly in such a way that movement of the arm by water-flow blocks the light path between the emitter and detector, which causes the photo-transistor output to go low, which releases the reset on the counter. The counter counts a predetermined time delay sufficient to avoid nuisance alarms due to temporary surges in the water conduit, and then activates the relay.

    摘要： 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.
