Abstract: A device that includes multiple light channels for separating the light from adjacent indicating lights and preventing bleed-over can be constructed to include an electrically conductive material so that the device can also serve as an EMI shield to reduce the amount of EMI escaping from a computer system chassis. By reducing light bleed-over from one indicating light to the next, such a device reduces the likelihood that a user will be confused about whether an indicating light is on or off. Additionally, closely spaced indicating lights can be accommodated by slots in the chassis while EMI is reduced by the shielding effects of the light channel device.

Abstract: An illumination system for a semi-tractor and trailer includes a pair of illumination housings, one attached to either side of the trailer just above the rear wheels. A reflector within each housing reflects light from a light source downward and outward through a clear lens to encompass an arc extending from the vertical to a predetermined angle, e.g. approximately 45 degrees from vertical. Light is thus directed onto the pavement and any objects immediately adjacent the trailer rear wheels to aid the driver in close quarter maneuvering, turns, and when changing highway lanes. A control circuit is connected to each light source and to the turn signal lead on the respective trailer side to provide steady power to the light source only when the turn signal and/or emergency flasher circuit is enabled. An optional amber lens can be provided on the side of each illumination housing to resemble the ordinary running lights on a typical semi-trailer.

Abstract: I have devised a distinctively styled light to assist others in locating the whereabouts of a party. This is particularly helpful when an emergency vehicle such as an ambulance has been summoned, or when aid has been requested of the law enforcement personnel through the emergency telephone numbering system. Difficulties are frequently encountered by parties seeking a particular address in areas where the identifying numbers are not well marked or are not marked at all. This is particularly true at night where the streets are poorly lighted or are not lighted at all. If emergency health service is involved such delays can cause serious problems.I have devised a simple method of making it possible for a driver to locate a particular residence or office without any unreasonable delay.
