    Abstract: A transmission gear shifter arrangement includes a shift lever assembly and a position sensor assembly each associated with a shifter housing. The shift lever assembly is operably coupled to a vehicle transmission, and is selectively movable to gear select positions corresponding to respective transmission gears. The position sensor assembly includes a light source and light sensor, where the sensor is configured to selectively receive light emitted from the light source. When the shift lever assembly is in a predetermined one of the gear select positions, the shift lever assembly enables light emitted from the light source to reach the sensor thereby indicating that the shift lever assembly is in the predetermined one of the gear select positions, and when the shift lever assembly is not in the predetermined one of the gear select positions, the shift lever assembly prevents light emitted from the light source from reaching the sensor.

    Abstract: A system for illuminating an object is provided, the system comprising a coherent or semi-coherent light source and a first diffuser positioned relative to the coherent or semi-coherent light source so as to receive said coherent or semi-coherent light. The first diffuser may diffuse the light to produce diffused light. An actuator having moveable elements, such as a moveable reflective and/or phosphorus surfaces, may be positioned to project the diffused light onto an object, and may be moved to project light onto different portions of the object. This movement may be performed with such rapidity that it is not perceived by a person viewing the object. Rather, the entire object would appear to be illuminated. Movement of the elements may be controlled by a computer, and may be performed according to a predefined routine.

    Abstract: Apparatus for interrupting and/or scanning a beam of penetrating radiation, such as for purposes of inspecting contents of a container. A source, such as an x-ray tube, generates a fan beam of radiation effectively emanating from a source axis, with the width of the fan beam collimated by a width collimator, such as a clamshell collimator. An angular collimator, stationary during the course of scanning, limits the extent of the scan, and a multi-aperture unit, such as a hoop, or a nested pair of hoops, is rotated about a central axis, and structured in such a manner that beam flux incident on a target is conserved for different fields of view of the beam on the target. The central axis of hoop rotation need not coincide with the source axis.

    Abstract: An aperture stop 10A includes a filter area 1 formed on a flat-plate substrate 23, and an aperture area 2 formed inside the filter area 1. The filter area 1 transmits infrared light and reduces or blocks the transmission of visible light. The aperture area 2 transmits light in the wavelength range corresponding to fluorescent light from an observed area of a subject and light in the wavelength range corresponding to illumination light to the subject. The aperture stop 10A does not reduce the light in the wavelength range corresponding to fluorescent light from the observed area of the subject, but variably reduces visible light since the area of the aperture area 2 is variable. Therefore, it becomes possible to simultaneously and clearly observe, with a simple method, a subject image formed by illumination light in the visible light band and an observed image formed by weak fluorescent light from the observed area of the subject in the infrared light band.

  • Patent number: 8164813
    Abstract: A continuous variable non-circular aperture for an infra-red camera is formed by a plurality of positionable metal blades arranged to define there between an aperture of non-circular shape. A rotatable actuator plate positions the blades. Actuator rotation in one direction moves the metal blades to increase the size of the non-circular aperture without changing the non-circular shape of the aperture and vice-versa when the actuator plate is rotated in the opposite direction also maintaining the non-circular aperture shape. A preferred non-circular shape for a continuous variable aperture now possible is a rectangle; another is configured as a racetrack.

    Abstract: A component for setting a scan-integrated illumination energy in an object plane of a microlithography projection exposure apparatus is disclosed. The component includes a plurality of diaphragms which are arranged alongside one another with respect to a direction perpendicular to the scan movement and which differ in their form and the position of which can be altered approximately in the scan direction so that a portion of the illumination energy can be vignetted by at least one diaphragm. The form of the individual diaphragm is specifically adapted to the form of the illumination in a diaphragm plane in which the component is arranged. This has the effect that at least parts of the delimiting edges of two diaphragms always differ in the case of an arbitrary displacement of the diaphragms.

  • Patent number: 7796316
    Abstract: A shutter includes micro-optics having first and second concentrator arrays. A transducer laterally displaces one of the first and second concentrator arrays between transmissive and shuttered modes. In the transmissive mode, the arrays of concentrators are optically aligned to permit electromagnetic energy passing through the first array of concentrators to pass through the second array of concentrators. In the shuttered mode, the electromagnetic radiation is blocked from passing through the second array of concentrators. The concentrators may be compound parabolic concentrators, or lenslets positioned on opposing plates with pinholes printed therethrough. The shutter may increase f-number of radiation passing therethrough, and may be used in a limited f-cone radiation source with shuttering abilities, for example reducing f-cone of radiation output from the radiation source.
