  • Publication number: 20070159833
    Abstract: A lighting fixture includes a heat sink having a first mounting portion attached to a housing. A first circuit board containing LEDs is mounted to a first side of a second mounting portion of the heat sink. A second circuit board include an LED control circuit is mounted to a second side of the second mounting portion. A multi-layer circuit board includes a heat-dissipating core bonded to first and second dielectric substrates, which are bonded to first and second electrically conductive layers. An electrical conductor extends through a through-hole in the board to electrically connect the first and second conductive layers. An electrical insulator inside the through-hole electrically isolates the core from the conductor. A transparent cover is shaped to cause downwardly projecting light rays emitted from the LEDs to be refracted more than upwardly projecting light rays. The cover also includes vertically extending projections for horizontally refracting light.

  • Patent number: 7214299
    Abstract: The method entails using capillary electrophoresis or capillary isoelectric focusing to separate intact microbes. The capillary system can be a conventional capillary tube or a microfluidic device. The method is employed to maintain the microbes intact to identify and/or quantitate the microbes. The identification of the microbe allows for the diagnosis of disease associated with the microbe.

  • Publication number: 20070097667
    Abstract: Provided is a cord seal for use in an underwater niche that comprises a seal cap and a main seal having a front side and a rear side and the main seal further includes a plurality of apertures that extend from the front side to the rear side. The cord seal can accommodate cords of two different sizes. The main seal also includes a plurality of splits to make it easier to install the cords. The main seal deforms to provide a water-tight seal despite the presence of at least one split in the main seal. In one embodiment, additional support structures are provided including a front seal support and a rear seal support. The front seal support has a plurality of projections that extend through the main seal and the rear seal support to connect each of the structures. The projections can be used to help spread apart the seal when it is desired to remove and replace a light assembly.

  • Patent number: 7110653
    Abstract: An optical network unit having an environmentally sealed printed circuit board arrangement within a first compartment and a signal in/out arrangement in a second compartment. The compartments are provided by two housings. Instead of replacing individual circuit boards in the case of breakdown or malfunction, replacement of the whole of the printed circuit board arrangement is necessary thereby eliminating human error and minimizing downtime. Two housings provide the two compartments. These housings are preferably mounted upon a housing mount and a carrier for the optical network unit is also preferably mounted upon the housing mount. This housing and carrier arrangement simplifies assembly and disassembly of parts of the unit for maintenance and replacement purposes.

  • Patent number: 7008533
    Abstract: Macrocyclic antibiotics having ring structures with at least 10 members act as separation agents in crystallization, precipitation, filtration, electrophoresis, and chromatography. The macrocyclic antibiotics include ansamacrolides, macrolides, macrocyclic peptides, polyenes and derivatives thereof. The process has been found to be especially advantageous for separation of optical isomers by electrophoresis and chromatography.

  • Patent number: 6985084
    Abstract: An electrically operated equipment with a sealed enclosure containing circuitry with an exterior visual indicator to show a state of operation of the equipment. The visual indicator is illuminated by a magnetic flux sensor also exterior to the equipment, the sensor inducing an electrical current from a sensed magnetic flux passing through a permeable wall of the enclosure. The magnetic flux is provided by a magnetic field generator within the enclosure. The generator is connected to the equipment to generate the field when the circuitry is operating correctly whereby the indicator shows a correct state of operation. The invention avoids the use of sealed orifices in the enclosure for conductors to pass to exterior LEDs or LEDs sealed within the enclosure and possible resultant leakage. The invention is useful for optical network units. The invention also includes a visual indicating device of multi-layer configuration and a method of visually indicating the operational state of circuitry.

  • Patent number: 5629595
    Abstract: An apparatus and method in which a vehicle is guided along a path defined by a centerline and left and right boundaries parallel to and spaced laterally on opposite sides thereof and in which a passenger in the vehicle can steer it for lateral movement between the boundaries. The method and apparatus utilize an electrical conductor to define the center of the pathway and a sensor for sensing the position of the vehicle relative to the electrical conductor. Based on a comparison of the position of the vehicle and the steering command received from the passenger, as well as the steer angle position of the vehicle, the vehicle is confined to a predetermined envelope, while permitting the passenger to steer the vehicle within the envelope.
