  • Publication number: 20110141584
    Abstract: A lens actuator module includes a lens assembly with an optical centerline and a clear aperture, a bearing guide integrated adjacent to the clear aperture with the centerline of motion substantially parallel to the optical centerline, a linear actuator with a preloaded frictional contact point that moves the lens along the centerline. The preload force is perpendicular to the optical centerline, constant and generated in-line with the contact point such that the preload force produces substantially zero additional friction in the bearing guide irrespective of the location along the optical centerline.

  • Patent number: 7922356
    Abstract: An illumination apparatus comprising an optics module wherein a driving circuit may be disposed within the proximal base portion of the optics module. The proximal base portion may further be releasably secured within an independent heat dissipating element. Such an apparatus may be very beneficial in light emitting diode (LED) applications due to its efficient conduction and dissipation of heat away from the LED semiconductor junction. Additionally, a releasable optics module comprising a plurality of LEDs and a driving circuit provides for cost efficient and environmentally friendly replacement of such a component at the end of its lifespan. The heat dissipating element (e.g. heat sink) may continue to be used, while only the optics module need be replaced or serviced as required. Precious environmental resources may thus be conserved and maintenance costs reduced while concurrently extending the lifespan of such an inventive illumination apparatus.

  • Publication number: 20110075914
    Abstract: The present disclosure concerns a method and system for assessing image quality of sub-images used to form a composite image using an algorithm developed by applying statistical correlation techniques to historical data on features of sub-images which were manually evaluated by experts and using those assessment to make decisions about the further processing of the sub-images which are being assessed. The method and system find particular value in the processing of sub-images generated while there is relative motion between the specimen under examination and the objective lens of a microscope such as when the microscope stage follows a planned traverse in the focal plane and a digital image is created at intervals correlated to the motion of the stage so that a region of interest in the specimen under examination is covered by the sub-images.

  • Patent number: 7911359
    Abstract: A light management system having networked intelligent luminaire managers. A plurality of networked luminaire managers, each collocated with a respective luminaire, monitor the status of their respective luminaires. The luminaire managers include transmitters for transmitting status information about their respective luminaires and third-party devices to a network server. The network server forwards the received status information from the networked luminaire managers to a computer of an owner/operator of the plurality of luminaires and/or a third-party user. The luminaire managers communicate with each other, whereby they form a network.

  • Publication number: 20100277067
    Abstract: A luminaire includes an Edison type electrical base, an optic, and a heat sink disposed between the base and the optic. An LED driver circuit is disposed at least partially within the heat sink, and is disposed in electrical communication with the base. An LED assembly is disposed in thermal communication with a surface of the heat sink, and in electrical communication with the driver circuit, the LED assembly includes an LED. The driver circuit includes circuitry that converts an AC signal at the base to a DC signal and provides the DC signal to the LED assembly, the circuitry includes holding current circuitry that produces a holding current for an electrical dimmer disposed upstream of the base in response to a current to the LED assembly being reduced for light dimming purposes.

  • Patent number: 7786648
    Abstract: A driving system in accordance with embodiments of the present invention includes a structure and a vibration system. The structure has at least one point to frictional couple to and drive a movable element in one of at least two directions. The structure also has at least two bending modes which each have a different resonant frequency. The vibration system applies two or more vibration signals which are at a vibration frequency to each of the bending modes of the structure. The vibration frequency is substantially the same as one of the resonant frequencies. At the vibration frequency one of the bending modes of the structure is vibrating substantially at resonance and the other of the bending modes of the structure is vibrating at partial resonance. The vibration system adjusts a phase shift between the two or more applied vibration signals to control which one of the at least two directions the moveable element is moved.

  • Patent number: 7770917
    Abstract: Disclosed are embodiments of apparatus, methods, and systems for inflatable curtain venting. In one embodiment, an inflatable curtain airbag is tested using a 50th-percentile dummy. The inflatable curtain airbag comprises a vent opening positioned such that during the crash test, the head of the 50th-percentile dummy strikes the airbag at the location of the vent such that the exit of inflation gas through the vent is at least partially blocked. The same inflatable curtain airbag may then be used in a test involving a 5th-percentile dummy, in which case the head of the 5th-percentile dummy would not strike the airbag so as to block the vent, thereby allowing for venting of the airbag.

  • Patent number: 7721608
    Abstract: The problems inherent with connecting a DUT to a test station have been solved by the use of a tray designed to allow a wide variety of different DUTs to be physically connected individually to a test station using a universal test station connector. The tray allows for the association therewith of a personality module which serves to provide the proper physical connections and to electrically condition the test station to the electrical characteristics of the DUT. The tray allows for sealed environmental testing of the DUT without impacting any physical connections between the DUT and the test station. The tray also allows for the DUT to be vibrated from externally applied motion without interfering with either the sealed environment around the DUT and without imparting motion to the physical connection between the DUT and the test station.

The threaded shaft has an axis of rotation which extends through and is at least partially engaged with at least a portion of the threaded passage. The driving system comprises at least two members operatively connected to the element. Each of the two members comprises two or more piezoelectric layers and electrodes which are coupled to opposing surfaces of each of the piezoelectric layers. The members are configured to expand and contract in a direction along the axis of rotation. The driving system is configured to subject the element to vibrations causing the threaded shaft to simultaneously rotate and translate in the direction along the axis of rotation through the element and apply an axial force in the direction along the axis of rotation.
