  • Patent number: 7938078
    Abstract: The present electric horn system includes a monolithic rigid housing member having a receiving opening for fixably housing, in a non-removable and secure manner following assembly, a compressor member, thereby preventing unintended separation and improving a reliability of the electric horn system. An acoustic sound wave generator includes an acoustic duct chambering system associated throughout with the monolithic rigid housing member. The acoustic sound wave generator receives compressed air from the compressor member to produce sound and propagate the same externally. A horn mounting system enables ready attachment of the system to a consumer-desired surface: mechanically, magnetically, adhesively, or via any other known attachment or mounting system. Optional weather and water resistant systems prohibit unintended water access to the electric horn system enabling use of the system in exposed weather conditions for improved user convenience.

  • Patent number: 7793607
    Abstract: A civil defense air powered siren includes an air powered tone generator, a compressed air tank, an air compressor, an air line with a control valve connecting between the compressed air tank and the tone generator. A pressure switch communicates with the compressor and the compressed air tank. The pressure switch activates the compressor to charge the compressed air tank when air pressure in the tank falls below a pre-selected limit. The control valve is remotely controlled preferably by a radio signal to cause the control valve to open the air line and supply the tone generator with air in order to cause a civil defense warning tone to be generated when it is appropriate to do so.

  • Patent number: 7501935
    Abstract: An audible output device, of a type usable in a fire alarm system, incorporates a multi-frequency waveform generator. The generator produces a plurality of frequencies with predetermined duty factors during various time intervals on a repetitive basis. The multi-frequency drive signal is in turn coupled to an audible output device such as a piezoelectric horn or the like. The multi-frequency audio output provides an indicator to persons adjacent to the device of the presence of an alarm condition.

  • Patent number: 6320513
    Abstract: A dirty filter indicator device adapted for use with a furnace, an air conditioning assembly and the like. As the filter collects dirt and dust, the overall airflow is restricted causing more air to flow through the whistle device. This increased air flow through the device alerts the occupants to the need to change the air filter. The device has a canopy cover to prevent large dust particles from clogging the device and an adjustable nozzle element which can be adjusted to begin whistling according to the degree of dirtiness of the filter by cutting portions of the distal end of the whistle.
