  • Patent number: 8054174
    Abstract: A referee's wireless horn indicator system having sensory alerts for aiding a referee in accurately officiating a sports event. The system includes a controller and a sensory receiver. The controller includes an official time clock for the sports event, a control circuit coupled to the official time clock, and a radio transmitter activated by a control circuit for sending a radio signal including time information to the sensory receiver. The sensory receiver is worn by the referee, for instance, on the wrist and includes a radio receiver and a sensory alerting device, such as a piezoelectronic speaker and a vibrator, where such sensory receiver is battery powered.

  • Patent number: 7218216
    Abstract: Referee's wireless horn indicator system for aiding a referee in accurately officiating in a sports event. The system includes a controller and a sensory receiver. The controller includes the official time clock for the sports event, a control circuit coupled to the official time clock, and a radio transmitter activated by the control circuit for sending a radio signal to the sensory receiver. The sensory receiver is worn by the referee, for instance on the wrist, and includes a radio receiver and a sensory stimulating device such as a vibrator, both battery powered. Upon the official time clock reaching zero, a signal is sent by the transmitter to the radio receiver which then activates the sensory stimulating device to impart a tactual signal to the referee, thereby apprizing him of the expiration of the time period.

  • Patent number: 6829852
    Abstract: An LED lighted sign with a light diffuser sheet with embedded diffusion particles which provides a 20%-40% increase in lighting transmittance. There is also provided a light divider assembly having partitions which serve to segregate groups of LEDs for lighting only selected segments of the light divider assembly for displaying numerical images. Alternatively, there is provided an injection molded light diffuser lens made of the same material as the light diffuser sheet which secures to each of several light diffuser chambers which combine to display numerical images. Optionally, colored LEDs may be used to create color displays. Color filters may also be overlaid the light diffusers or color pigment may be added to the diffusion material during injection molding to create color displays. A molded light divider assembly is also provided in the alternative. Alternatively, a circuit board having arrangements of different colored LED strings which can be illuminated one or more at a time can be provided.

  • Patent number: 6831306
    Abstract: An extended length light emitting diode suitable for auto-insertion including an extended LED body region serving as a standoff or spacer to provide supported spacing from a circuit board to extend the LED die through a faceplate for suitable viewing and to serve as a structure through and about which the lower body portion of the LED and the LED leads can be stabilized and sealed to a printed circuit board. An alternative embodiment includes structure for sealing an LED to a faceplate.

  • Patent number: 6707683
    Abstract: A circuit board having improved soldering characteristics having raised structure consisting of spacer pads arranged to provide for vertical distancing of electrical or electronic components from the component side planar surface of the circuit board. Such spacing is complementary to top vented soldering stations where the spacing allows solder process gases to flow unimpeded from the soldering stations through the spacing to atmosphere.
