  • Patent number: 8614632
    Abstract: This device, by its organization and operation, processes sound, usually music. It provides output voltages, for driving lights, which is proportionally representative of input sound levels. Range of sound perception of the human ear exceeds the range of perception of the human eye. It is necessary to adjust the sound level by compression and Automatic Gain Control, particularly by compression, to accommodate the eyes. A requirement to have the output drive voltage drive the lights is to have a linear response to the compressed audio signal. This requirement is met with an output drive circuit which, has a linear response to the compressed signal. This is achieved with a linear firing circuit when providing output voltage using SCR's or Triacs. In a straightforward variation of the output circuit to improve the power factor, the linear response is maintained by modulating the output with transistors instead of using SCR's or Triacs.

    Abstract: An overcurrent protection circuit connected between a voltage input and a voltage output of an electronic device to protect against excessive current is disclosed. The overcurrent protection circuit includes first to fifth resistors, a relay comprising a coil and a normally closed switch, a pnp transistor, and a break-over element. When a current between the voltage input and the voltage output is greater or equal to a rated current of the electronic device, the npn transistor is turned on, while the coil is powered on to control the switch to be opened, therefore the voltage output cannot output voltage, which can protect against excessive current damaging the electronic device.

  • Patent number: 8004420
    Abstract: A security lighting system and method are intended to dispel and/or affect unwanted humans or animals by providing lighting that varies with a suitable switching frequency, such as between 5 and 70 Hz. The lighting of a light source of the system may be varied by a control unit as to intensity, color, pattern etc., with a preferred switching frequency being between about 15 and 20 Hz for humans. A proximity detector may be provided to activate the system when an unwanted presence is detected. Such varying lighting causes feelings of physical and psychological discomfort, which have found to be effective in chasing away animals and dispelling or disorienting humans.

  • Patent number: 7907047
    Abstract: An apparatus and concomitant method of reducing the number of synchronization pulses transmitted to the alarm units for increasing the reliability of the overall alarm system is disclosed. The synchronization signal is implemented as a reference or reset signal from which the alarm units derive a reference time to begin activation of the alarm units. Thus, when an alarm unit receives a reference synchronization pulse, the alarm unit applies the reference synchronization pulse as a reference point in time to trigger a series of flashes or audio tones. A second signal sent in close proximity to the synchronization signal is implemented to trigger a second function of the alarm units, such as a silence function.

  • Patent number: 7876234
    Abstract: A gauge gives a driver of a tow vehicle a visual cue that the trailer is at a proper depth within the water to recover a boat onto the trailer. The gauge has a tubular member that has a top with a red light bulb and a green light bulb thereon. A housing is attached to the tubular member and longitudinally adjusted along a length of the tubular member as needed. A switch, controlled by a float, is located within the housing, such that when there is no water in the housing, the float is at rest and causes the switch to connect the red light bulb to electricity. As water enters the housing, the float rises with the rising water level in the housing and causes the switch to disconnect the red light bulb from and connect the green light bulb to the electricity.

  • Patent number: 7843326
    Abstract: The disclosed system provides headgear, i.e., a Firefighter Helmet, with forward illumination that also acts as a personal rescue detection system for quickly finding a downed of lost firefighter. More specifically, the headgear includes a forward illuminating light that has unique characteristics that are easily detected in a smoke filled space by using a handheld photodetector probe that is tuned to the exact characteristics of the light source. The handheld probe has a somewhat narrow directional response to allow a directed search for a downed firefighter or other emergency personnel in a smoke filled noisy environment that hinders normal visual and audible search methods. The handheld photodetector probe produces a unique audio tone that is proportional in volume to the intensity of the exact-characteristics-light-source thus allowing a sweeping motion of the probe to immediately determine the relative direction to a firefighter who is down or requiring assistance.
