  • Patent number: 9150152
    Abstract: A lighted vehicle cargo area arrangement includes a cargo area wall structure and a lighting system. The cargo area wall structure includes a first wall surface facing a vehicle cargo area. The lighting system includes a rail, a mounting bracket and a lamp. The rail is fixedly coupled to the cargo area wall structure and defines a lamp receiving space located laterally between an outboard surface of the rail and the first wall surface. The mounting bracket includes a rail attachment section rigidly attached to the rail and a lamp attachment section. The lamp is attached to the lamp attachment section. The lamp is aimed to shine light beneath the mounting bracket and the rail toward the vehicle cargo area.

  • Patent number: 9086211
    Abstract: Embodiments described herein provide optical systems that can mix colors to produce illumination patterns having a large area with uniform color. One embodiment of an optical system can include a set of optical units that each produces an illumination pattern with uniform color and intensity. The optical units are spaced so that the individual illumination patterns overlap to create an overall illumination pattern with an overlap area. In the overlap area, the colors emitted by the individual optical units mix to create a desired color. Embodiments of optical systems can provide beam control so that the optical units emit a high percentage of light in beam.

  • Publication number: 20150131261
    Abstract: Embodiments described herein provide an optical system having a light source (e.g., LED) and a high numerical aperture multi-element optical stack. According to one embodiment, the optical stack can reimage an entrance aperture. The multi-element optical stack can include a number of optical elements forming a series of lenses. The series of lenses comprises, a first lens positioned to receive light emitted in a first beam angle and a second lens more distal from the LED than the first lens, the second lens defining a second lens exit aperture that has at least a minimum area necessary to conserve radiance for the emission beam angle in air. The lenses in said series of lenses are configured, in combination, to successively reduce a beam angle of light from the first beam angle to the emission beam angle.

  • Patent number: 8449128
    Abstract: Embodiments disclosed herein provide optical systems utilizing photon conversion materials in conjunction with a light source and an LED. An LED can be positioned in a cavity defined by a base and one or more sidewalls. Phosphors can be disposed on the entrance face of a lens between the entrance face to the lens body and the LED so that light emitted from the LED will be incident on the phosphor and down converted before entering the lens body through the entrance face. The lens can positioned so that the phosphors are separated from the LED by a gap.

  • Patent number: 8302847
    Abstract: A system for monitoring the parking status of vehicles incorporating a plurality of wireless identification tags, each tag having a unique tag identifier and having association with a selected vehicle. The system also includes a portable scanner to be used by a parking monitor, the portable scanner having a processor executing instructions thereon, a tag scanner capable of reading a wireless identification tag of a selected vehicle located in relatively close proximity over a wireless link, and a communication device capable of communicating over a wireless wide area network to transmit information about vehicle parking status. A server, having a database with fields for each of the selected vehicles, communicates with the portable scanner over the wireless wide area network to log data related to vehicle parking status. A software program may also be used to facilitate communication between the scanner and the vehicle owner and/or between the scanner and a tow service.

  • Patent number: 6223984
    Abstract: An intelligent card reader is provided to replace existing magnetic stripe readers, bar code readers, and Wiegand effect readers without the need for expensive retrofitting of existing computer systems which are coupled to the existing readers. The intelligent card reader can replace the aforementioned readers and yet remain compatible with their existing interfaces by emulating a magnetic card reader, a Wiegand effect reader, or a bar code reader. Moreover, the card reader can accept smart cards having different functions and/or software interfacing techniques, thus allowing different types of smart cards can be used in the same reader. A reprogramming feature allows the unit to be easily reprogrammed to support new features and smart card types without rewiring or removing the unit.

  • Patent number: 5327327
    Abstract: The multi-chip circuit module of the invention comprises a plurality of circuit chips assembled in a laminated stack. Each chip includes a plurality of layers of thin film interconnect patterns in the normal configuration, except for the final layer or layers, which comprise a reroute pattern that locates all circuit input and output pads along a single edge of each chip. The relocated pads are provided with contact bumps to facilitate the addition of a bonded lead to each I/O pad extending therefrom to a point beyond the edge of each chip. Thus, upon lamination the protruding tips form an array of leads on a single lateral face of the laminated chip stack.
