  • Patent number: 11119028
    Abstract: An optical particle sensor comprises at least first and second light sources of different wavelength for sequential operation. An optical detector is used to detect light from the light sources emitted or scattered by particles to be sensed. A current injection compensation signal is also provided which is dependent on which light source of the optical arrangement is in use. The compensation signal means the amplifier does not need to re-settle in response to different background illumination levels associated with the different light sources. In this way, detection signals may be obtained in quick succession from different light sources.

  • Patent number: 10856391
    Abstract: A method to correct signal light intensities measured by a detector of a detection unit in a laboratory instrument is presented. The detection unit comprises a light source, a sample plane comprising a sample holder configured to hold at least one sample vessel comprising a test sample to be illuminated, a reference light sensor, and the detector. Based on a basic light intensity of a newly manufactured light source and an initial light intensity measured by the reference light sensor the sensitivity of the reference light sensor can be determined. And signal light intensities measured by the detector can be corrected based on the determined sensitivity and subsequently measured reference light intensities of the reference light sensor in order to generate comparable test results.

  • Patent number: 10845363
    Abstract: The present invention recognizes that current clinical laboratory testing methods for multiparametric single cell analysis are limited to analysis of intact live cells, and are insufficient for identification of signaling activation profile defining certain cell types, including but not limited to neoplastic and immunologically activated cell subsets. One aspect of the present invention generally relates to marker selection in panels to include proteins routinely assessed in standard FCM, while preferably also incorporating markers for surface receptor proteins within activated signaling cascades.

  • Patent number: 10845583
    Abstract: A scanning microscope includes a scanning unit that causes irradiation light emitted by a light source to scan a sample, an optical system that guides the emitted light that has passed through the scanning unit to the sample, an isolation unit that includes a transmissive portion that enables the irradiation light to pass the transmissive portion and a reflective portion that reflects at least some of light that is included in emitted light generated from the sample as a result of the irradiation light being radiated to the sample and that has passed through the optical system and the scanning unit, and a detection unit that detects the emitted light that has passed through the isolation unit. The isolation unit is disposed in an optical path of the irradiation light between the light source and the scanning unit.

  • Patent number: 10831026
    Abstract: A retina scanning type display apparatus includes a scanning portion, a deflection member, and a light flux diameter expanding element. An incidence angle range in a first incidence direction with respect to an eye from the deflection member is broader than an incidence angle range in a second incidence direction, and, in the light flux diameter expanding element, an expanding magnification of light flux diameter in a first expanding direction, which corresponds to the first incidence direction, is greater than an expanding magnification of light flux diameter in a second expanding direction, which corresponds to the second incidence direction. In addition, in the scanning mirror, a width in a first scanning direction, which corresponds to the first expanding direction, is narrower than a width in a second scanning direction, which corresponds to the second expanding direction.

  • Patent number: 10823952
    Abstract: An instrument for scanning a specimen on a specimen holder. The instrument includes a scanning stage for supporting the specimen and a detector having a plurality of pixels. The scanning stage and the detector are movable relative to each other to move the specimen in a scan direction during a scan, and at least some of the pixels of the detector are operable to collect light inside the specimen during the scan and generate corresponding image data. The instrument also includes a processor operable to perform MSIA on the image data and to generate two or more strip images. Each strip image has a different effective exposure. The processor combines the two or more strip images to generate an increased dynamic range (IDR) image of the specimen.
