Abstract: A modular warning signal light system comprising at least one support. The at least one support having at least one module receiving port. The module receiving ports constructed and arranged to removably receive the support engagement member of a module. Each module having at least one visible side. The at least one visible side having at least one light emitting diode light source engaged thereto. The at least one light emitting diode light source, module and support all in independent electrical communication with a controller. The controller constructed and arranged to selectively activate the at least one support, the at least one module, the at least one light emitting diode light source, and any combinations thereof to create at least one warning light signal.

Abstract: A method and system for monitoring relay status using a lighting control panel is disclosed. The lighting control panel is used, for example, to control lighting throughout a building. The method includes the steps of commanding at least one relay to an on or off position from the lighting control panel, monitoring the status of the at least one relay from the lighting control panel, and setting the state of an indicator on the lighting control panel to show relay OFF, relay ON, or relay failed based on a monitored relay status.

Abstract: A display unit has multiple illuminators provided in a housing of the unit. The display unit has a right prism composed of at least four side faces each with a unique color and being detachably connected with a step motor. The display unit is able to provide the necessary brightness by means of the illuminators when the ambient light is not sufficient.

Abstract: An indicating device of a portable computer is disclosed. The indicating device utilizes a light guiding board to guide the light emitted from LEDs to indicate different status of the portable computer. The light guiding board includes the first, second, and third surfaces. The light emitted from LEDs is received by the first surface, further reflected by the second surface, and then sent out through the third surface to form a diffusion light and to show the status of the computer.

Abstract: A remotely controlled electronic display sign which operates with a plasma display and which provides for humidity and heat control and the like allowing the sign to be used in various environments. The sign is essentially self-contained and includes those components necessary for enabling a display of desired material from a remote control source or one located at the sign. A controller in or associated with the sign is accessible either electrically, or through satellite transmission or other wireless transmission from the remote source which allows the display of the sign to be changed at will. Thus, an operator at a remote source may, with the aid of a pre-prepared graphic design, transmit that design to the controller at or associated with the sign for display of that graphic information and potentially with sound.

Abstract: A combination meter for a vehicle has a speedometer, a tachometer, a gauge and a warning light disposed in a casing. A holding panel having an annular wall and a rear wall is attached to the casing so that the speedometer, the tachometer, the gauge and the warning light are exposed through openings formed in the rear wall. The speedometer analog-displays a speed of the vehicle using a dial and a pointer and digital-displays a speed of the vehicle using an EL panel disposed at a front side of the dial and attached to the holding panel. An EL drive circuit for driving the EL panel is mounted on an outer surface of the annular wall of the holding panel. As a result, the EL panel and the EL drive circuit are readily attached to the casing simultaneously when the holding panel is attached to the casing, thereby improving an efficiency in attachment and replacement of the EL panel and the EL drive circuit.

Abstract: An improved board ID number display mechanism whereby an LCD or LED or similar display is utilized on the backplane of a circuit card. The display is viewable for outside the computer case, making it possible to ascertain the board's ID number without having to open up the computer case and examine jumper or switch patterns.

Abstract: A dart target with a function of automatically displaying scores is disclosed. The dart target is installed with a damping panel. The damping panel is formed by at least one damping layer; the damping layers are made of flexible and transmitted cloth, such as sisal, non-woven cloth, etc. Thus, metal dart can be used. As the dart passes through the target panel, it can be damped by the damping layer and fixed. A pattern is formed at the surface of the first damping layer so that the dart player may identify the target. The target panel is a plane for being used by metal dart needle, and the score can be displayed properly. The target unit is constructed by a sisal block and a frame box.

Abstract: An edge illuminated sign is provided with a light dispersal to guide light from a light source into an edge of the sign. The light source is an LED and the light dispersal is a triangular prism provided with a recess for enclosing the LED.

Abstract: A fiber optic display sign has an optical system with enhanced light efficiency so that the display system is suitable for outdoor use. A number of fiber optics have light receiving ends arranged in a compact bundle for receiving an image from an image generator, the fiber optics coupling the image to the output ends thereof for display. An array of lenses is positioned adjacent the output ends of the fiber optics for directing or aiming the light from the fiber optics to control the viewing angle of the image displayed. The array of lenses may be fixed with respect to the output ends of the fiber optics or the lens array may be movable with respect thereto so as to vary the viewing angle. The image generator employs a light source formed of a densely packed array of white light emitting diodes to provide enhanced brightness.

Abstract: Feedback is provided to a user during installation of electronic equipment. Prior to installation of the electronic equipment, a plurality of installation feedback lights are placed on a case of the electronic equipment. During installation of the electronic equipment after attempting performance of an installation step, a determination is made as to whether performance of the installation step was successful. When performance of the installation step was successful, notification is provided to an installer that the installation step was successful. The notification includes activating one of the installation feedback lights.
