  • Publication number: 20080031004
    Abstract: A LED vehicle lamp structure installed in a vehicle lamp assembly comprising a housing, a lens, and a reflector is disclosed to include standing boards each having a top edge, a bottom edge, a height defined between the top edge and the bottom edge, and LEDs. By means of the arrangement of the LEDs on the standing boards to match with the heights of the standing boards between the respective top edges and the respective bottom edges, the light-emitting heads of the LEDs constitute an array that fits the variation of the curvature of the reflector and lens of the vehicle lamp assembly, thereby greatly lowering the cost and the manufacturing difficulty of the vehicle lamp assembly.

  • Patent number: 7262022
    Abstract: Methods of fixing and processing tissue and samples on a membrane by using ultrasound radiation as a part of the method are presented. Ultrasound of a frequency in the range of 0.1-50 MHz is used and the sample or tissue receives 0.1-200 W/cm2 of ultrasound intensity. The use of ultrasound allows much shorter times in the methods. Also presented are apparati comprising transducers of one or of multiple heads for producing the ultrasound radiation and further comprising a central processing unit and optionally comprising one or more sensors. Sensors can include those to measure and monitor ultrasound and temperature. This monitoring system allows one to achieve accurate and optimum tissue fixation and processing without overfixation and tissue damage. The system also allows the performance of antigen-antibody reactions or nucleic acid hybridizations to be completed in a very short time while being highly specific and with a very low or no background.

  • Patent number: 7252107
    Abstract: A foldable enclosure structure containing a fabric cover defining a desired shape when expanded to an expanded position; a first supporting frame fixedly attached to the cover and a second supporting frame provided within the cover and rotatably coupled to the first frame such that the second frame is movable between a collapsed position and an expanded position. The second frame is superposed over the first frame in the collapsed position for ease of storage, but is rotated axially to intersect with the first frame in the expanded position to prop up the cover to the desired shape. To ensure that the structure is stable in the expanded position, fixing means is/are provided for fixedly attaching the second frame to the first frame in the expanded position.

  • Publication number: 20060216744
    Abstract: Methods for treating biological samples on microscope slides are set forth. One aspect of the invention is the use of predried reagents in wells on trays onto which the slides are placed, especially the use of predried reagents which dissolve sequentially. Yet another aspect of the invention is the use of external controls placed directly on a microscope slide in conjunction with a biological sample to be assayed. The external controls can be conveniently placed on a membrane which can be affixed to the slide. A further aspect of the invention is a specially designed tray to allow whole chromosome painting of all chromosomes of a cell sample on a single slide. The invention is also drawn to a coverslip with concave wells which act as reaction chambers when placed against a slide and filled with buffer. Preferably a reagent is predried in the well.

  • Patent number: 6703247
    Abstract: Slideholders which are useful for manually or automatically processing biological samples on microscope slides are described. These slideholders hold multiple slides and are designed in conjunction with specialized trays for rapidly processing the mounted biological samples such as for immunocytochemical staining. The slideholder plus tray assemblies incorporate several useful advantages including a requirement for minimal reaction fluid volumes, ease of handling several slides concurrently, prevention of evaporation of reaction fluids, protection of the biological sample from extraneous environmental contamination, and the ability to perform in situ PCR. Various aspects of the design aid in removing trapped air from the reaction fluids and in adding fluids to the biological sample. One embodiment comprises a coverstip with a soft top which aids in prevention of tissue degradation by preventing pressure buildup during PCR.
