  • Patent number: 10308550
    Abstract: A device for applying radiation to a target is provided. The device includes a radiation emitter to emit electromagnetic radiation having a peak emission wavelength in the range from 10 nm-1 mm, and a first reflector that extends in a length direction with a concave cross section. The first reflector defines a cavity area having a perimeter, and includes an inward facing reflective border for at least 50% of the perimeter of the cavity area. Radiation is provided to the cavity area with an intensity distribution I and a maximum intensity Imax. The cavity area includes a focal area defined by all points at which a normalized intensity I/Imax is greater than 0.2. A width of the focal area is 0.0001-0.5 times a width of the cavity area.

  • Patent number: 9664371
    Abstract: A lamp head assembly is provided. The lamp head assembly includes a thermally conductive block, an inlet cooling fluid pipe coupled to the thermally conductive block such that a cooling fluid is configured to pass from the inlet cooling fluid pipe to the thermally conductive block, and a metal heat exchanger secured to the thermally conductive block. The metal heat exchanger defines a plurality of internal channels to distribute cooling fluid provided by the inlet cooling fluid pipe. The metal heat exchanger is secured to the thermally conductive block such that the cooling fluid is configured to pass from the thermally conductive block to the plurality of internal channels defined by the metal heat exchanger. The lamp head assembly also includes a plurality of light producing elements secured to the metal heat exchanger.

  • Publication number: 20070158358
    Abstract: A vending machine includes at least one width-adjustable storage rack, the storage rack having a fixed wall and a movable wall connected to the fixed wall by at least one connecting link; and an adjustment mechanism constructed and adapted to position the movable wall relative to the fixed wall and to thereby vary an interior width between the fixed and movable walls. Two movable walls can be connected to a single fixed wall.

  • Publication number: 20060011642
    Abstract: A light curtain device for use in a vending machine which has at least one mechanism arranged for initiating operation upon selection by a customer for vending an article into a vend space through which the article falls into a customer-accessible hopper. The light curtain device has first and second emitter/detector arrays, each comprising at least one emitter and a plurality of detectors, said arrays being positionable and arrangeable within said vending machine so that electromagnetic radiation emitted by said at least one emitter of said first array may be detected by at least some of said plurality of detectors of said second array, and so that electromagnetic radiation emitted by said at least one emitter of said second array may be detected by at least some of said plurality of detectors of said first array, and so that articles falling through the vend space of the vending machine will interrupt electromagnetic radiation between at least one emitter and at least one detector.
