摘要:
A coupler is provided which may be incorporated into a handheld communications device to permit the handheld device to be acoustically coupled to a variety of telephone handsets. The device may include a spring-biased, adjustable microphone arm onto which a microphone is mounted in order to acoustically couple the microphone to the telephone handset. The microphone arm may be adjustable to adapt to a variety of telephone handset styles, such as cellular telephones or cordless telephones, in order to permit the acoustical coupling to be achieved with a large number of different telephone handsets.

摘要:
An exemplary embodiment relates to a cooling system and a method for cooling an electronic display. A preferred embodiment includes a transparent gas cooling chamber. The transparent gas cooling chamber may have a linear polarizer. The components in the system are preferably housed within the electronic display housing. The cooling chamber defines a gas compartment that is anterior to and coextensive with the electronic display surface. Fans may be used to propel the isolated gas through the cooling chamber. The circulating gas removes heat directly from the electronic display surface by convection. The isolated gas is transparent or at least semi-transparent. The image quality of an exemplary embodiment remains essentially unchanged, even though the gas is flowing through a narrow channel over the visible face of the electronic display surface.
摘要:
A backlight device for a liquid crystal display containing a substantially planar light guide with a light emission surface and a light-collecting portion opposing the light emission surface. A pair of opposing side portions may define the periphery of the light guide. A first plurality of LEDs are placed so as to direct the emitted light into the light-collecting portion. An NVIS filter is preferably placed adjacent to at least one of the side portions. A second plurality of LEDs are placed to direct the emitted light through the NVIS filter and into a side portion of the light guide. Alternative embodiments can contain NVIS filters and LEDs along additional edge portions of the light guide. Some embodiments may use directing elements or slanted surfaces of the light guide to direct the light from the second plurality of LEDs into the edge portions of the light guide.
摘要:
Preferred embodiments utilize a plurality of optical channels to effectively aim the light emitted by a liquid crystal display (LCD). Embodiments may also change the nominal and range of viewing angles of light in two or three dimensions in order to confine the emitted light towards the intended observer.
摘要:
A preferred embodiment relates to controlling the amount of backlight in an electronic display to account for the temperature in the backlight cavity. Another embodiment relates to a system for controlling the amount of backlight based on both the temperature in the backlight cavity and the amount of ambient light. The embodiments are especially useful in electronic displays which are subjected to cold or warm temperatures and displays which are placed in very bright environments. Exemplary embodiments allow the display to remain visible, while avoiding possible damage due to high levels of heat or cold.
摘要:
An assembly for cooling an electronic image assembly having a rear channel placed behind the image assembly and a heat exchanger for accepting ambient air. The system contains a first fan placed within the heat exchanger to force ambient air through the heat exchanger and the rear channel. A second fan may be used to force circulating gas through an interior portion of the display housing and through the heat exchanger in order to transfer heat to the ingested ambient air.
摘要:
A system and method for speaker configuration in an audio and video housing, wherein the audio and video housing may be supported by stands located on top of a gas pump. The audio and video housing may have an audio and video source, at least one video display, and circuitry to drive the pair of speakers. The speakers may have a covering to provide protection from moisture and foreign particles. The speakers may be positioned to output sound downward directed towards the top of a gas pump. The sound may then be redirected to a first and second listening area.
摘要:
A system for cooling an electronic image assembly using a heat exchanger with an internal fan assembly. Circulating gas may also be used to cool a front portion of the electronic image assembly or any other internal cavity of the electronic display housing. The circulating gas may be drawn through a heat exchanger so that heat may be transferred to an ambient gas. The heat exchanger may have an internal fan assembly for drawing ambient air through the heat exchanger and exhausting it out of the display housing. The heat exchanger may be divided into two portions so that the fan assembly is placed between the two portions.
摘要:
A system and method for remotely-identifying the components and/or software revisions within an electronic display. An electronic storage device may be placed within an electronic display assembly and placed in electrical communication with a network connection. The electronic storage device may contain identification numbers for one or more components or software revisions within the display. A computing device may be in electrical communication with the network connection so that the identification numbers on the electronic storage device may be accessed remotely. If a particular component or software revision is desired, the computing device may be used to search the contents of each electronic storage device at each display to determine which displays contain the desired component or software revision.
