  • Publication number: 20210327745
    Abstract: A pickup and contact device is adapted to be connected to a moving device to move a picked-up electronic element to an electrical testing zone. The moving device pressurizes the electronic element through the pickup and contact device, so that a contact point of the electronic element stably contacts a contact pad of the electrical testing zone. The pickup and contact device includes a main body including a base and a contact portion and a plurality of heat dissipation fins disposed at two opposite sides of the base. The contact portion is adapted to pick up the electronic element and to move the electronic element to the electrical testing zone along with the moving device. When the electronic element is tested in the electrical testing zone, heat emitted from the electronic element is adapted to be transmitted out through the heat dissipation fins of the main body.

  • Publication number: 20210279472
    Abstract: A computing device captures a live video of a user. For a first frame of the live video, the computing device obtains first target positional coordinates of a first target point located a first predetermined distance from the computing device and obtains first background data. For a second frame, the computing device obtains second target positional coordinates of a second target point located a second predetermined distance from the computing device and obtains second background data. The computing device calculates a target motion vector based on the first target point and the second target point and calculates a background motion vector based on feature points in the first background data and the second background data. The computing device determines a difference value between the target motion vector and the background motion vector and determines whether the user is spoofing the computing device based on the difference value.
