Abstract: An in-ground inspection lighting system, particularly an in-ground inspection lighting system for underside of vehicles including an elongated, embedded light transmitting optical fiber in a polymeric mass, remotely energized, and placed into a pre-determined channel formed in a medium such as concrete or asphalt, whereby the embedded embodiment does not protrude from the channel and is essentially flush mounted in the medium. Alternatively, an in-ground inspection lighting system including, an elongated embodiment of linear light emitting diode assemblies embedded in a polymer mass and placed into a pre-determined channel formed in a medium such as concrete or asphalt, whereby the embedded embodiment does not protrude from the channel and is essentially flush mounted in the medium. The linear embodiments to provide a steady, uniform flood of light up to the underside of a vehicle to be inspected.

Abstract: A readily portable handheld security assessment device that may be manipulated for viewing the underside of objects having low ground clearance, including a series of solid state light sources distributed around the perimeter of therein mirror for uniformly illuminating the field to be viewed. A flexible ball joint assembly allows a reflector or mirror to be easily and controllably positioned and oriented under the object to facilitate visual inspection thereof while permitting the user to remain erect.

Abstract: A portable vehicle inspection system including a series of mats into which two lengths of flexible, polymeric side light transmitting optical fiber extend along channels placed near the edges of the mats, and at a distance to be within the tracks of wheels of a vehicle passing thereover, with the polymeric fiber optic including notches and a reflector directed to provide a steady, uniform flood of light up to the underside of a vehicle to be inspected, and between the inspection zone, and the light source, the polymeric optical fiber is covered by an opaque jacket to prevent light from radiating outward.

Abstract: An LED coupled to a large core plastic optical fiber light guide with a tubular connector having a first bore into which the light guide is inserted, a second bore into which the LED and its attached wires are inserted and a third bore adjacent to the first bore, extending between the first and second bores and into which the LED is positioned so that when illuminated the LED transmits light into the guide with the first bore. The connector includes helical threads formed in the first bore into which the guide is threaded to securely retain the guide within the first bore and which form a seal to prevent contaminants from entering the region in the first bore adjacent the LED.

Abstract: The present invention is directed to a heat shrink clad-core optical conduit surround by multiple layers of jackets and a method of manufacturing the same. The jackets are formed with a thickness and index of refraction that is preferred for generating an aura effect. The aura effect appears when light transmitted through the core appears to be traveling seamlessly through the entire core, cladding and jackets and may even appear to illuminate the space surrounding the outer most jacket, thus, producing an aura that makes the fiber optic conduit appear larger than it is. The preferred embodiment may include interlacing layers of materials that provide optical characteristics, such as dichroic and holographic films, that are enhanced by the aura effect.

Abstract: A waterproof coupling for use in conjunction with illumination systems for swimming pools, spas, and the like, employs a light conduit placed within the waterproof fitting to provide safe light for underwater use by keeping any source of electricity remote from the water. Some embodiments may be removed from the pool. Others are permanent.
