Abstract: A rotatable transmission electron microscope (TEM) grid holder includes first and second legs orthogonally positioned with respect to each other. Each clamp holder leg is configured to be received within a hole in a main stage supporting the rotatable TEM grid holder. When the first leg of the clamp holder is affixed within the main stage, the sample has a first orientation with respect to the FIB, and when second leg of the clamp holder is affixed within the main stage, the sample has a second orientation with respect to the FIB, rotated 90° relative to the first orientation. The sample may be rotated back and forth between the first and second orientations multiple times as needed to produce a sample which may be clearly imaged by the TEM system, substantially free of curtaining effects.

Abstract: A client device obtains a request from a user to retrieve makeup information from a cloud server and obtains a digital image of a facial region of the user. The client device transmits the digital image to initiate a communication session with the cloud server without obtaining login credentials from the user, wherein the cloud server retrieves a makeup session packet by matching the transmitted digital image with one of a plurality of digital images in the cloud server and transmits the makeup session packet comprising a corresponding selection of cosmetic products. The client device receives the makeup session packet and extracts the selection of cosmetic products by the client device and generates a user interface displaying the selection of cosmetic products. The client device performs virtual application of the selection of cosmetic products onto the facial region of the user.

Abstract: A makeup evaluation computing device obtains a request from a user to initiate a makeup evaluation session. The makeup evaluation computing device initiates the makeup evaluation session without obtaining login credentials from the user and obtains a digital image of a facial region of the user. The makeup evaluation computing device generates a user interface displaying at least one cosmetic product and obtains from the user a selection of cosmetic products among the one or more displayed cosmetic products. The makeup evaluation computing device performs virtual application of the selected cosmetic products on the facial region of the user and stores the selection of cosmetic products. The makeup evaluation computing device generates a makeup session packet comprising the digital image of the facial region of the user and stored selection of cosmetic products. The makeup evaluation computing device transmits the makeup session packet to a cloud server and terminates the makeup evaluation session.

Abstract: A ball ejector includes a base, a housing, a ball conveyer, an ejecting frame, and a reduction gear box. Thus, when the ball on the ball track of the housing is pushed by the ball conveyer to reach the trigger of the ejecting frame, the cam of the ejecting frame is driven to trigger and move the elastic plate to hit the ball to eject the ball outwardly from the housing successively so as to perform a successive ball ejecting action. In addition, the ejecting frame is movable upward and downward relative to the housing by rotation of the adjusting threaded rod to adjust the height of the ejecting frame so as to adjust the ball ejecting height and angle of the ejecting frame.
