  • Publication number: 20230087664
    Abstract: A device configured to provide a value indicative of fluorescent emission from a substrate 5 having a test region is provided. The device comprises an electromagnetic radiation source configured to emit excitation radiation towards the test region to excite fluorescent emission from a fluorescent material in the test region. The electromagnetic radiation source is configured such that a variation in intensity of the excitation radiation across the test region is less than 15%. The device further comprises a sensor configured to capture a primary 10 image of the fluorescent emission, and a controller configured to modify the primary image based on calibration data and to use the modified image to obtain the value indicative of the fluorescent emission.

  • Patent number: 10390405
    Abstract: The disclosed systems and methods emphasize driving LEDs in series and in parallel with the same LED driver chip and a single inductor. For creating overlap, the systems and methods of LED color overlap disclosed herein take advantage of the fact that green and blue LEDs have the same voltage. Thus, green and blue LEDs can be driven in parallel as needed. LED suppliers can screen parts for sufficiently close voltage matching between green and blue LEDs. This is especially true when using green LED die based on a blue die with a green phosphor. Cyan may be produced by driving a green LED and a blue LED in parallel. White may produced by driving a green LED and a blue LED in parallel and a red LED in series with this green and blue parallel pair.

  • Patent number: 7973999
    Abstract: In accordance with particular embodiments, a system for displaying modulated light includes a spatial light modulator comprising a plurality of micromirrors having a pixel pitch less than 17 micrometers. The system also includes an intermediate voltage generator operable to generate a negative voltage and a positive voltage. The system further includes at least two level shifters coupled to the intermediate voltage generator. The system additionally includes a reset driver coupled to the at least two level shifters and to at least a subset of the plurality of micromirrors. The reset driver is operable to drive the subset of the micromirrors. The spatial light modulator, the intermediate voltage generator, the at least two level shifters, and the reset driver are all incorporated on a common substrate.
