  • Patent number: 9241392
    Abstract: Digital Control Ready (DCR) is a two-way open standard for controlling and managing next-generation fixtures. A DCR-enabled lighting fixture responds to digital control signals from a separate digital light agent (DLA) instead of analog dimming signals, eliminating the need for digital-to-analog signal conditioning, fixture-to-fixture variations in response, and calibration specific to each fixture. In addition, a DCR-enabled lighting fixture may also report its power consumption, measured light output, measured color temperature, temperature, and/or other operating parameters to the DLA via the same bidirectional data link that carries the digital control signals to the fixture. The DLA processes these signals in a feedback loop to implement more precise lighting control. The DCR-enabled lighting fixture also transforms AC power to DC power and supplies (and measures) DC power to the DLA via a DCR interface.

    Abstract: An optical probe system having a probe with an optical guide (G) having a distal end. The optical guide (G) is mounted inside a housing (H) so that the distal end is displaceable with respect to the housing (H). A set of actuators (A), e.g. electromagnetic drive coils, can displace the distal end by application of a drive signal (Vx, Vy). A control unit (CU) generates the drive signal (Vx, Vy) so as to provide a scanning frequency which varies according to an amplitude of the drive signal (Vx, Vy). With such probe system it is possible to scan a field of view with a scanning frequency that varies with the scanning radius. Taking into account the maximum allowable drive current, it is possible to increase scanning speed compared to scanning at the mechanical resonance frequency of the optical system, since small radii can be scanned at a high scanning frequency.

  • Publication number: 20140320852
    Abstract: A light beam is applied to a front surface of an optical depolarizer. The depolarizer rotates the polarization of light received on different surface positions by different amounts, so that the average incoming polarization is scrambled. The depolarizer has a first and second body that transmit first and second polarization components of the beam with mutually different speeds of light. Each body has two wedge shaped parts of variable thickness, corresponding wedge shaped parts in the two bodies providing light paths of substantially position independent lengths, but with variable rotation of polarization. The wedge shape parts of the front body form a concave input surface for the incoming beam. This prevents cross-over of light between the different wedge shaped parts.
