  • Publication number: 20240107873
    Abstract: The present invention relates to organic light-emitting devices comprising (a) an anode, (i) a cathode, and (e) an emitting layer between the anode and cathode, comprising 2 to 40% by weight of a triplet emitter X having a difference of the singlet energy (ES1(X)) and the triplet energy (ET1(X)) of less than or equal to 0.4 eV [?(ES1(X)) ?(ET1(X))?0.4 eV], 0.05 to 5.0% by weight of a fluorescent emitter Y and 55 to 97.95% by weight of a host compound(s), wherein the amount of the triplet emitter X, the fluorescent emitter Y and the host compound(s) adds up to a total of 100% by weight and the singlet energy of the triplet emitter X(ES1(X)) is greater than the singlet energy of the fluorescent emitter Y(ES1(Y)) [(ES1(X))>ES1(Y)].

  • Publication number: 20240094329
    Abstract: Described herein is an illumination source adapted to generate a regular pattern integrated into a portable device, the illumination source including an array of light emitting diodes or laser light sources and a diffractive optical element. Also described herein is a detector including the illumination source, an array of optical sensors, where each optical sensor is configured to generate a sensor signal in response to an illumination of its respective light-sensitive area, and an evaluation device adapted to evaluate the sensor signal.

  • Publication number: 20240085518
    Abstract: Described herein is a mobile device with an optical detector including: at least one illumination source adapted to generate at least one illumination pattern for illuminating an object, where the illumination pattern includes a regular and/or constant and/or periodic pattern; at least one sensor element having a matrix of optical sensors, the optical sensors each having a light-sensitive area, where each optical sensor is configured to generate at least one sensor signal in response to an illumination of the light-sensitive area by at least one light beam propagating from the object to the detector; and at least one evaluation device adapted to determine at least one region of interest.

  • Patent number: 10065332
    Abstract: A thin layer is cut from a foam material body using a band-knife. A take-off device that lifts and removes the layer from the cutting site, includes a belt conveyor with an electrostatically chargeable conveyor element. The layer is lifted and removed from the cutting site by electrostatic attraction to the conveyor element.
