  • Patent number: 11928885
    Abstract: Embodiments of the present application provide a fingerprint identification method, a fingerprint identification apparatus and an electronic device. The fingerprint identification method is applied to a fingerprint identification apparatus disposed under a display screen of an electronic device, the fingerprint identification apparatus includes a pixel array and a colour filter layer, the colour filter layer includes at least one filter unit, and the at least one filter unit is disposed above at least one first type pixel of the pixel array, respectively, and the method includes: capturing a first light signal transmitting through the at least one filter unit and sensed by the first type pixel; determining a fingerprint identification environment according to an intensity of the first light signal; and determining, based on the fingerprint identification environment, a target capturing parameter of capturing a fingerprint light signal, the fingerprint light signal being used for fingerprint identification.

  • Patent number: 11369575
    Abstract: Pharmaceutical particles having an inner portion comprising an agonist of peroxisome proliferator-activated receptor ? (PPAR?) and a biodegradable polymer; and an outer coating comprising an emulsifier which surrounds the inner portion, wherein the agonist may be a fibrate, and the particle contains at least about 5 wt % to about 25 wt % of the agonist, and wherein the particle has a sustained delayed release of the agonist in a range of at least about 1 to 12 months when in an aqueous solution or physiological environment. The pharmaceutical particles may be used, for example, to treat diseases and conditions such as ocular disorders which benefit from PPAR? agonism.
