    Abstract: A detection device, a detection apparatus, and a detection method are provided. The detection device includes a detection assembly and a driving assembly. At least two rows of detection units are provided, and the detection units are arranged in a matrix along the first direction and the second direction. During detection, the driving assembly may drive one or both of the to-be-detected object and the detection assembly to move along at least one of the first direction and the second direction, so that the detection units scan different areas of the surface of the to-be-detected object, thereby realizing a scanning of the entire surface. That is, the scanning of the surface of the to-be-detected object is completed by using multiple detection units, which improves detection efficiency for the to-be-detected surface, and realizes a relatively high imaging quality.

  • Patent number: 11443716
    Abstract: In some implementations, a mobile computing device may participate in the calibration of an output signal of a media device. This calibration process includes storing device-specific calibration data which is related to properties of a light sensor of the mobile device. The mobile device then detects of properties of light emitted by the display device during a presentation to obtain sensor values related to light emitted by the display device during the presentation. The calibration process may also ensure that the mobile device is proximate to the display device prior to obtaining the sensor values. The collected sensor values are adjusted using device-specific calibration data stored to the mobile device to normalize the sensor values relative to a baseline. These normalized sensor values are sent to the media device for use in adjusting the output signal based on the normalized sensor values.

  • Patent number: 11432547
    Abstract: Identification and evaluation of a set of first-in-class potent inhibitors targeting a new cancer target, Grb2-associated binder-1 (GAB1), which integrates signals from different signaling pathways and is frequently over-expressed in cancer cells. Intensive computational modeling is utilized to understand the structure of the GAB1 pleckstrin homology (PH) domain and screened five million compounds. Upon biological evaluation, several inhibitors were found that induced large conformational changes of the target structure exhibited strong selective binding to GAB1 PH domain. Particularly, these inhibitors demonstrated potent and tumor-specific cytotoxicity in breast cancer cells. This targeting GAB1 signaling may be used for cancer therapy, especially for triple negative breast cancer patients.
