    Abstract: A method and system for implementing a serial enclosure management interface is disclosed. In one embodiment, the LED indicators for a storage device in an external enclosure are managed. First, a set of bit patterns for driving the LED indicators is repeatedly placed on a serial bus that is connected to an external enclosure for transmission by varying the states of the serial bus. This process continues until a change to this set of bit patterns is detected. In one embodiment, the change is captured in a memory mapped register, which is typically accessible by a storage device controller. The detected change prompts accesses to a virtualized register, which generally resides in system memory, to generate a different set of bit patterns to place on the serial bus.

  • Patent number: 7330129
    Abstract: An apparatus and method for obtaining data stored in an electronic module within a power tool over a power line cord of the tool, and without any disassembly of the tool being required. An interface subsystem applies a high frequency, low power AC input signal to the power cord of the tool. A controller within the tool recognizes this signal as an indication that the tool is to be placed in a communications mode. The controller modulates a power switching device used for turning on and off the motor of the tool in such a fashion that current pulses are transmitted over the power line cord back to the interface subsystem. The current pulses correspond to tool usage/performance/identification information stored in the electronic module of the tool. This information is interpreted by a current reader circuit of the interface subsystem as binary information which is then transmitted to an external computing device for analysis and/or recording.

  • Patent number: 6894623
    Abstract: A display monitor is provided for a multi-optical-path photoelectric safety apparatus including a plurality of multi-optical-path photoelectric sensor units. The user can determine whether a special function such as blanking is set for each optical path in a group which comprises a plurality of indicator lamps placed in a row along a longitudinal direction. The user can check the light incidence/light block status for each optical path on an indicator lamp group. The display monitor includes the plurality of indicator lamps placed in a row in the longitudinal direction. First and second switches allow the user to select the unit and the optical path to be shown on the two indicator lamp groups.

  • Patent number: 6816137
    Abstract: An alphanumeric and graphic symbol display device in which an LED array is rotated and controlled to project a display onto a translucent surface. The electrical power for the array is provided by way of a rotating contactless transformer independently of the control data for the array which is provided by infrared data transmission through a tubular shaft driven by a DC brushless, three-phase motor to rotate the array at a predetermined rate independent of the electrical power for the array and the control data.

  • Patent number: 6741225
    Abstract: In order to provide a device for generating an image on an image surface with N×M image elements which can be illuminated individually, comprising a plurality of semiconductor radiation sources, each of which generates radiation with at least one color, an optical imaging means with a beam guidance, by means of which a plurality of image elements can be illuminated with each of the semiconductor radiation sources, with which it is possible to generate an image on an image surface in as simple a manner as possible using radiation sources, it is suggested that the image surface (12) be divided into a plurality of continuous image surface sections (14), each comprising a two-dimensional ensemble of image elements (16), that an illumination unit (20, 220, 320) be associated with each of the image surface sections (14) and that each illumination unit (20, 220, 320) have at least one semiconductor radiation source (30) and at least one optical imaging means (40, 240, 340) of its own associated with this illum

  • Patent number: 6504488
    Abstract: In an electronic device having a housing containing electronic components and a front part connected to the housing and having control elements, the connections between the electronic components and the control elements are made using a first transmitter and a second receiver on the front part respectively aligned with a second receiver and a second transmitter on the housing. This arrangement obviates the need for mechanical connections which are susceptible to faults between the housing and the front part.

  • Patent number: 6441750
    Abstract: A solid state traffic control signal adapted to facilitate light alignment and viewing angles during installation. The traffic control signal includes a video camera or a detachable optical sighting system with a grid representing the various viewing angles of individual LED's for quick alignment and viewing angle programming. This system greatly reduces the amount of trial-and-error and multi-man requirements for installation.

  • Patent number: 6433703
    Abstract: A signaling device includes a housing that may be releasably coupled to a fishing reel. The housing includes a transparent front wall defining an opening for receiving a fishing line of the reel therethrough. An incandescent light, battery, and light sensor are positioned within the housing. The light sensor permits current from the battery to energize the light when the level of ambient light is less than a predetermined level. A switch assembly is positioned in the housing and includes an arm pivotally mounted for teetering movement, the arm having a first arm with an eyelet through which the fishing line may extend and a second end adjacent to the battery. Changes in line tension at the first end causes the second end of the arm to move away from or toward the battery. Contact with the battery permits current to energize the light sensor and thus the light.

  • Patent number: 6323781
    Abstract: An electrically steerable solid state light apparatus is ideally suited for traffic controls. There exist many applications where a driver wishes limited viewing angles of traffic signals for safety, one example being left hand turn arrows. Current state of the art for solid state traffic signals involves the use of a mechanical louver to block the light from the unintended traffic lanes. This approach reduces the intensity of the light and customization of the viewing angle available to the DOT (Department of Transportation).
