  • Patent number: 9677739
    Abstract: Provided is an optical diffuser apparatus, for use adjacent a light engine in a lighting fixture for producing desired color-mixed light output. The apparatus includes a first diffuser panel and a second diffuser panel connected to the first diffuser panel. The first diffuser panel and the second diffuser panel are configured and arranged so that, when the apparatus is positioned for operation within the fixture, light emitted by the light engine at greater than a pre-determined threshold angle with respect to a centerline of the engine will pass through both the first diffuser panel and the second diffuser panel, thereby mixing colors of the light toward the desired color-mixed light output.

  • Publication number: 20150026094
    Abstract: A system, such as a reliability target system (RTS), can determine a customer driven reliability target (CDRT) for a product, such as an electronic device or system. The CDRT can be a target reliability or quality score or a target value, such as a mean time between failures target value. The system may include one or more hardware modules (such as hardware modules including software) configured to: select a high availability mean time between failures (HA); determine a predicted mean time between failures (pMTBF), such as according to industry standard procedures; determine a field mean time between failures (fMTBF), such as according to historical customer experience information associated with the product and/or a product competing with the product.

  • Publication number: 20080005838
    Abstract: A system and method for determining and monitoring various characteristics of a patient positioned on a patient support apparatus, such as a bed, stretcher, or cot, is disclosed. The system and method involve monitoring the forces exerted by the patient on one or more force sensors, which may be load cells on the support apparatus. These force sensors will detect vibrations that correspond to various conditions of the patient, including the patient's heart rate, breathing rate, and/or the seizure status of a patient. These vibrations may be analyzed, such as by Fast Fourier Transforms, in order to determine the various conditions of the patient.

  • Patent number: 6124674
    Abstract: A switch controller for providing on/off timing control of lights including a base unit, an electronic unit, and a cover unit. The electronic unit includes two printed circuit boards, one of which includes an integrated circuit controller for controlling an LCD display and for permitting input of timing information via buttons associated with the LCD display, and the other of which supports a relay, neon lamp, and transistors. The relay includes a pair of reed contacts for connecting a light to a power supply in response to the timing information. The neon lamp is dimmed whenever the switch is in an off status in order to provide a guide to enable location of the switch controller in the dark.

  • Patent number: 6069847
    Abstract: A timer has an upper cover, a mounting base and a circuit board. The space between the upper cover and the mounting base is used to accommodate the circuit board. The upper cover and the mounting base are fixed together by way of fixing poles and screws. At one side of the circuit board is disposed a number of conducting legs some of which are integrally formed and coupled to the connecting pins of electronic components by welding and are secured to the circuit board at the same time so that the assembly of the timer of the present invention is time saving in production and safer in use.

  • Patent number: 5699320
    Abstract: An improved socket set with a timer has an upper cover and a lower shelter that are combined to form a case in which a timer, a circuit board, an IC board and two socket seats are housed. The timer can be easily removed and selectively oriented in one of four orthognal directions. The socket seats can also be removed and limitedly refined by turning 90 degrees around so as to facilitate the installation of the socket set in different situations.

  • Patent number: 4015778
    Abstract: A multifunctional outdoor folding chair comprising two generally U-shaped open frames, one major and outer and the other minor and inner, braced pivotally one within the other to support a detachable seat which, in turn, supports pivotally a detachable back panel. The two frames are braced at points generally midway between the ends of the paired cross legs thereof by a common fastener. Rows of bosses under the seat serve to connect with locking channels on the planar top portions of the two frames, and the chair height can be adjusted by choosing the appropriate boss row for connection with the major frame. A storage chamber is attached between the leg portions of the minor frame adjacent the lower ends, and another storage shelf is built onto the undersurface of the seat. The back panel, by means of angle joints at the rear end thereof, is mounted onto the seat through locking slits thereon. Different game board patterns are printed on the top of the seat, and on the back and the front of the back panel.
