  • Patent number: 10392640
    Abstract: Disclosed is a method for modifying starch to slow down the digestion rate of modified starch. The present invention utilizes two-stage GBE treatment to convert the long straight-chain starch molecules into highly branched molecules with compact structures so as to decrease the digestion rate of the starch. During the two-stage treatment, granular starch was first treated with GBE, the treated starch was gelatinized in boiling water, and the gelatinized starch was treated with GBE for a second time, leading to an enhanced effect of GBE modification. Compared with the one-staged GBE modification, the two-stage GBE modification can further increase the content of slowly digestible starch in the modified starch and thus decrease the digestion rate of starch.

  • Publication number: 20190257876
    Abstract: Defects in an electronic device are detected by capturing a first image from a first side of the electronic device, and capturing a second image from a second side of the electronic device which is different from the first side. The first and second images are captured when an inside of the electronic device is illuminated by light rays passed therethrough. If a defect is present in the electronic device, a profile of the defect is determined based on the first and second images and the electronic device is rejected if it is assessed from the profile of the defect that it is of a type for which the electronic device should be rejected.

  • Patent number: 10387710
    Abstract: An electronic device includes an image sensing display. The display includes a cover glass and is configured as a waveguide. A volume holographic grating in the display diffracts incident light from an object positioned outside the display. The diffracted incident light has an angle of incidence relative to the volume holographic grating that satisfies the Bragg condition. The volume holographic grating diffracts the incident light through the waveguide at a predetermined angle and with a predetermined waveguide exit distance to focus at the image sensor. An image sensor is positioned at an output of the waveguide to capture the diffracted incident light propagated through the waveguide. Image processing circuitry is coupled to the image sensor to recognize a fingerprint image captured by the image sensor through the waveguide.
