  • Patent number: 7926213
    Abstract: An electronic sign having slotted frame cabinets whereby each slotted frame cabinet can conveniently be attached to one or more vertically or horizontally positioned adjacent slotted frame cabinets by using connecting components which are generally located around the periphery of one or more slotted frame cabinets. Connecting components including splice bars, splice plates, and mounting clamps are aligned in, positioned along and secured to backing bars which are co-located in backing bar slots in one or more of the slotted frame cabinets. Lift eyes can be variably located in one or more lift eye slots. The use of externally located connecting components, which do not extend through the cabinetry, minimize the entry of environmental elements into the interior of the electronic sign. Multiple slotted frame cabinets can be connected without the removal of LED display panels.

  • Publication number: 20110051409
    Abstract: An LED panel assembly includes a circuit board having a plurality of LEDs. An LED seal louver is coupled over the circuit board. The LED seal louver includes a substrate and a pliable seal membrane. The substrate includes one or more substrate cavities. The pliable seal membrane is coupled with the substrate, and the pliable seal membrane includes a pliable material partially extending across the one or more substrate cavities. One or more LED passages extends through the pliable material adjacent to the substrate cavities. Each of the LED passages is sized and shaped to receive a single LED. Bulbs for one or more of the plurality of LEDs are correspondingly received within the LED passages, and the pliable material seals around each bulb with an interference fit. The bulbs are directly visible through the LED seal louver while the pliable seal membrane is sealed around the bulbs, and the circuit board is concealed by the LED seal louver and isolated from an environment exterior to the LED panel assembly.

  • Patent number: 7869198
    Abstract: The present invention provides a multiple seal electronic display module having displacement springs for distributed use as major components of an electronic sign. Displacement springs are provided to displace the electronic display module from the front of an electronic sign mounting panel until latching mechanisms are properly actuated in order to secure the electronic display module to the electronic sign mounting panel and thus provide a visual clue indicating proper or improper securing. A configured front edge seal provides for multiple surface sealing of multiple components consisting of, but not limited to, a louver panel, an LED circuit board, and a housing. A rear seal is also provided to seal the rear of the electronic display module to the electronic sign mounting panel. Input and output signal jack base seals and a power jack base seal provide effective seals between the housing and the signal and power jacks.

  • Patent number: 7605772
    Abstract: An electronic display panel having a combination of aligned and connected forwardly located panels to which a plurality of rearwardly located LED modules easily and readily secure using three-point attachment to form an electronic display panel suitable for accommodation by and for securing to the structure and framework of a sign system. Configured spacer brackets offer mutual spaced support between the front and rear panels and are constructed using arcuate geometry for dimension minimalizing to prevent interference with the viewing of the LED pixels. Notches are located along the bottom edge of the electronic display panel for simple engagement, such as with an arcuate surface of a pivot bar incorporated in a lower structure of a sign system.

  • Patent number: 7502950
    Abstract: A dual power supply switching system for use in an electronic sign where independent suitably sized power supplies each capable of independently powering an entire plurality of LED display modules supply power on an alternating distributed basis to the plurality of LED display modules. A microcontroller having an odd or even address on each LED display module controls the connection of the respective LED display module to a particular power supply by controlling onboard solid state switches and, upon sensing an inadequate power source supply, switches to the other power supply to re-establish power to the LED display module.

  • 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: 7161558
    Abstract: Electronically programmed signs consist of any array of picture elements (pixels) that can be controlled independently to create an image. Varying the intensity of each pixel and adding multiple colors per pixel will enhance the image quality. It is currently common to have displays that use one, two or three separate colors in a pixel (monochrome, red-green, and red, green and blue) with intensity levels of two, four, eight up to 256 and beyond. Multiple colored pixels can combine colors at various intensity levels to expand the displayable color palette.
