Abstract: A surgical cannula is provided for illuminating a surgical cavity using an optically transparent walled passageway having a working channel. Light from a light source is received by the surgical cannula and is emitted by the walled passageway to illuminate the working channel, such that both tissues accessible via the working channel and tissues surrounding the walled passageway are illuminated.

Abstract: A phototherapy device including a flexible light emitting pad is provided. The phototherapy device allows an infant to be swaddled while the infant simultaneously receives phototherapy treatment on his/her front, back, and sides without the use of external light sources.

Abstract: An illumination assembly for illuminating an automotive component. The illumination assembly includes a light guide that emits light along its length and that has a shape of the automotive component.

Abstract: A low-power non-contact proximity sensor with improved sensitivity. In particular, the non-contact proximity sensor includes a capacitive sensor decoupled from a surrounding environment by a guard ring. Both the capacitive sensor and the guard ring are driven by a direct current (DC) power source, with the guard ring driven based on feedback from the voltage applied to the capacitive sensor.

Abstract: Light emitters are made of one or more cladded flat optical fibers having opposite flat sides and disruptions along at least a portion of the length of the fibers to cause light entering at least one end to be emitted from at least one side. The ends of the flat optical fibers may have substantially the same thickness as a light source and a width substantially equal to or substantially greater than the width of the light source for ease of optically coupling one or more such light sources to the flat optical fiber ends.

Abstract: Intraoral phototherapy devices receive light from an associated light source and propagate the light into an oral cavity of a patient. The device comprises a light guide that receives light from an external light source. The light guide comprises a main body portion made of an optically transparent soft flexible biocompatible polymeric material sized and shaped to conform to contours of the oral cavity when inserted therein to direct the light to targeted regions of the oral cavity. The main body portion comprises a pair of spaced apart side wings sized and shaped to be received between a patient's teeth and cheeks on opposite sides of the oral cavity and a center flap intermediate the side wings for transmitting and directing the light to targeted regions of the oral cavity. A controller delivers light to the light guide in a controlled manner.

Abstract: A backlit system comprises a base panel, a plurality of keys disposed on the base panel, a substantially planar light guide panel disposed between the base panel and the plurality of keys, at least one light source disposed on the light guide panel, and at least one light management feature disposed on the light guide panel. The at least one light management feature is configured to at least partially reflect incident light within the light guide panel.

Abstract: Lighting assembly comprises an optical fiber light guide panel member having a light conducting core cladded on opposite sides by cladding made of optically transparent material having a lower index of refraction than the light conducting core to cause total internal reflection of conducted light within the light conducting core at the core-cladding interface. Disruptions at one or more areas of the cladding cause conducted light within the light conducting core to be emitted from one or more areas of the panel member. Electrical circuitry is bonded to one or both sides of the cladding. One or more LEDs embedded in the panel member are in electrical conduct with the electrical circuitry and optically coupled to the light conducting core.

The light source may comprise one or more LEDs that generate a blue light output and at least one other LED that generates a different color light output.

Abstract: A method of marring a fiber optic substrate by supporting a length of the substrate on a tapered surface of an elongate support and causing relative movement between at least one roller and the support lengthwise of the support with the roller pressing the substrate against the tapered surface and the roller rolling along the substrate. At least one of the roller and the support include an abrasive surface for marring the substrate during such relative movement therebetween.

Abstract: A display front lighting device comprises an optically transmissive sheet member that provides reflective means to evenly distribute light for the illumination of the text and/or graphics of display modules while permitting the text and/or graphics to visibly pass through the sheet member for viewing. The transmissive sheet member has LEDs offset mounted at an angle relative to one side of the sheet member such that a portion of the light emitted by the LEDs is reflected by the one side onto the adjacent dis play. The LEDs are mounted on a flexible printed circuit board, or alternatively on the conductive traces bonded to the sheet member.
