    Abstract: A point-of-sale advertising system for use with a display case having a front glass sheet positioned in front of a cavity for accepting goods, the system containing a transparent LCD positioned behind the front glass sheet, and a plurality of LEDs positioned adjacent to one pair of opposing edges of the LCD and arranged so that light which is emitted from the LEDs is directed backwards towards the cavity. Further embodiments may also contain a door assembly and frame surrounding the front glass sheet and LCD, a switch positioned to determine when the door assembly is open or closed, and electrical circuitry adapted to turn off the LEDs when the door is open and turn on the LEDs when the door is closed.

    Abstract: An electronic display assembly for an electronic display includes a front panel having a perimeter and a housing. An ingestion gap ingests, and an exhaustion gap exhausts, open loop fluid. The ingestion and exhaustion gaps are each located along a vertical and horizontal portion of the perimeter. A channel is positioned behind the electronic display. A fan causes the open loop fluid to flow from the ingestion gap through a first gas pathway to the channel and from the channel to a second gas pathway and out the exhaustion gap.

    Abstract: A system and method for preventing image retention in an electronic display. A time threshold (TT) and a pixel threshold (PT) may be defined. The system preferably performs a checksum calculation of all pixel data within an active image area of the electronic display for an interval of time until reaching TT. The system may then compare the checksum calculation for each interval of time to determine if the change in pixel data is less than PT. Preferably, the system will perform an image retention prevention method for the active image area if the change in pixel data is less than PT. Generally, this is performed by transmitting alternate pixel data to the electronic display.

    Abstract: A pair of electronic displays are placed back to back and are configured for mounting to a vehicle. A pair of thermal plates are located behind the electronic displays and a pair of transparent plates are located in front of the electronic displays. A closed loop of air travels vertically through the space between the electronic displays and transparent panels and through a closed loop plenum. An open loop of air travels horizontally through the space between thermal plates and the rear surface of the electronic displays.

    Abstract: The embodiments herein provide a device for sealing an interface having an opening for a wire to pass through the interface. A pair of sealing blocks may be used where one block contains a protrusion and the opposing block contains a recess. The protrusion and recess preferably have an apex with a round having approximately the same dimension as the radius of the wire. A pair of posts may be positioned on opposing sides of the opening. One sealing block may contain an aperture for accepting one of the posts while the second sealing block may contain an aperture for accepting the opposing post. The posts may be threaded so that they can accept a threaded fastener. Exemplary embodiments may utilize mounting plates which may contain a flange such that squeezing the opposing flanges together can cause inward forces on the sealing blocks.
