  • Patent number: 11921251
    Abstract: Inductive position sensors for sensing relative position (e.g., relative rotary position) between members are provided. In one example implementation, the inductive position sensor includes a transmit aerial having at least one transmit winding. The inductive position sensor can include a receive aerial having one or more receive windings. The inductive position sensor can include a coupling element operable to be disposed on the second member. The inductive position sensor can include processing circuitry configured to provide one or more signals indicative of the position of the first member relative to the second member based on current induced in the one or more receive windings resulting from an oscillating signal provided to the transmit winding. The inductive position sensor includes at least one electrostatic shield. The electrostatic shield can include a plurality of conductive traces arranged so that no current loops are formed in the electrostatic shield.

  • Publication number: 20230314924
    Abstract: A system may include a projector subsystem in a theatre projecting fight toward a screen, a sensor measuring light levels of the projected light, and a processing device. The projector subsystem may project light such that there is a hazardous light area and a non-hazardous light area of an audience seating area. The processing device may receive a measured light level of projected light from the sensor. The processing device may determine a second light level between the hazardous light area and the non-hazardous light area based on the measured light level and the position of the light projected over the audience seating area. The processing device may compare the second light level to an unsafe threshold light level. The processing device may determine a configuration for the system such that the light level of projected light in the non-hazardous light area is less than the unsafe threshold light level.

  • Patent number: 11307241
    Abstract: A method is disclosed for maintaining a desired optical output in a solid state illumination device, where the device is configured to accommodate multiple light emitting diodes (LEDs) and to combine light from the LEDs to produce a single optical output. The method includes testing the LEDs before adding them into the device. The testing produces characterizing information that describes how one or more optical properties (e.g., optical power and/or peak wavelength) of the tested LED change with temperature. This characterizing information is stored in a computer-based memory of the device, and the tested LED is added (connected) into the device. Then, during operation, temperature sensors measure a temperature associated with each respective LED in the device, and electrical current to one or more of the LEDs can be adjusted based on the measured temperatures associated with each LED and its stored characterizing information.

  • Patent number: 10082658
    Abstract: A high power microscopy illumination system is disclosed, having a liquid cooled, Solid State Light Source (SSLS) unit including one or more LED light sources, thermally mounted on a cold plate, which is cooled by a closed-loop liquid cooling system including a remote unit housing a heat exchanger. The SSLS unit with the LED light source is compact and lightweight, and is mechanically and optically directly coupled to the illumination port of the microscope, for efficient optical coupling to the imaging plane. High capacity cooling of the LEDs, enables the LEDs to be driven at higher current densities for increased optical output and for operation with improved thermal stability. The LED driver circuitry may also be housed within the SSLS unit and liquid cooled. The SSLS unit is vibrationally isolated from vibration-causing components of the cooling system, such as cooling fans and other bulky components, which are housed in the remote unit.

  • Patent number: 9239133
    Abstract: A solid state illumination system is disclosed, wherein a light source module comprises a first light source, comprising an LED and a phosphor layer, the LED emitting a wavelength ?1 in an absorption band of the phosphor layer for generating longer wavelength broadband light emission from the phosphor, ??PHOSPHOR, and a second light source comprising a laser emitting a wavelength ?2 in the absorption band of the phosphor layer. While operating the LED, concurrent laser pumping of the phosphor layer increases the light emission of the phosphor, and provides high brightness emission, e.g. in green, yellow or amber spectral regions. Additional modules, which provide emission at other wavelengths, e.g. in the UV and near UV spectral bands, together with dichroic beam-splitters/combiners allow for an efficient, compact, high-brightness illumination system, suitable for fluorescence imaging and analysis.
