Audio signaling device and method

An audio signal device carried by a dog operable to provide separate audio signals indicating to a dog handler movement of the dog and a stationary condition of the dog comprising:

• electrically operated audio signal generator means operable to produce a sound, electronic circuit means electrically connected to the signal generator means to drive the signal generator means whereby the signal generator means produces an audible sound, an electric power source, on-off switch means connected to the power source and the circuit means, said switch means when turned on electrically connecting the power source and circuit means, and means for supporting the circuit means, power source, and switch means, said circuit means having means responsive to the movement of the dog to provide electric power to the signal generator means whereby the signal generator means produces first audio signals, said means of the circuit means including a first mercury switch connected to the power source and signal generator operable to supply power to the signal generator in response to movement of the dog, said circuit means further including a capacitor, and a second mercury switch operable to discharge the capacitor in response to movement of the dog, said means of the electronic circuitry being responsive to a stationary condition of the dog to withhold electric power to the signal generator means for a limited period of time whereby the signal generator means does not produce audio signals and then provide electric power to the signal generator means whereby the signal generator means produces second audio signals, said second audio signals being different from the first audio signals whereby movement or stationary condition of the dog can be ascertained by the dog handler.

A signal device carried by a dog operable to provide separate signals indicating to a dog handler movement of the dog and a stationary condition of the dog comprising:

• electrically operated signaling means operable to produce signals to inform the handler of the moving and stationary conditions of the dog, electronic circuit means electrically connected to the signaling means to drive the signaling means whereby the signaling means produces a signal, an electric power source connected to the circuit means, and means for supporting the circuit means and power source, said circuit means having first motion detection switch means connected to the power source and signaling means responsive to movement of the dog to provide electric power to the signaling means whereby the signaling means produces a first signal, means for storing electrical power, and second motion actuated switch means operable to discharge the means for storing electrical power in response to movement of the dog, said means of the electronic circuitry being responsive to a stationary condition of the dog to withhold electric power to the signaling means for a limited period of time whereby the signaling means does not produce a signal resulting in a silent period and then produce electric power to the signaling means whereby the signaling means produces a second signal, said second signal being different from the first signal whereby movement or stationary conditions of the dog can be ascertained by the dog handler.
