  • Electronic sound level control in audible signaling devices
    Patent number: 9576442
    Abstract: In further development of U.S. Pat. No. 6,310,540 B1, an audible signal device comprising of a microprocessor or microcontroller and a sounder element, or a microprocessor or microcontroller in conjunction with electronic circuitry such as discrete components, inductors, or IC's with a sounder element where the resulting sound pressure level is controlled by changing the drive signal's frequency, size, shape, and/or duty cycle.
    Type: Grant

  • Water resistant audible signal
    Patent number: 6987445
    Abstract: The invention is an modified audible signal, such as a piezoelectric noise-making and audible signaling device, which further includes a hydrophobic covering material, such as polytetrafluoroethylene (PTFE). The hydrophobic covering material is known to be water resistant, but does not effect the sound of the audible signaling device, thereby delaying or preventing the failure of the audible signaling device from water corrosion.
