The present disclosure relates to a driving circuit and a wireless power transmitter including the same. In view of the fact that a transmitter-side coupling circuit exhibits a high resistance when an AC current having a frequency far away from its operating frequency is applied to input terminals, the present disclosure connects a plurality of transmitter-side coupling circuits which operates at different operating frequencies in parallel at output terminals of the same inverting circuit. The controller controls an operating frequency of the AC current output from the inverting circuit to drive different one of the transmitter-side coupling circuits to operate. Thus, one driving circuit can drive the transmitter-side coupling circuits which operate at different operating frequencies or under different technical standards to supply electric energy. The driving circuit is compatible with wireless power receivers which operate at different operating frequencies, and thus has improved compatibility.

Embodiments of the present application disclose an anti-passback method, apparatus and system. A plurality of access controllers are communicatively connected to a server. After detecting that a card reader has successfully read an identifier of an access card, an access controller sends the identifier of the access card, an identifier of the card reader, and its own identifier to the server. The server searches for the identifier of the card reader that read the access card last time, and the identifier of the access controller corresponding to the card reader, and determines a route for the door opening request. When the determined route exists in a preset list of routes, the sever sends a door opening instruction to the access controller. The route list may include routes between doors under the control of the plurality of access controllers. When a user swipes on a card reader on any of the doors with an access card, the access controller that controls the card reader will transmit information to the server. The server determines whether to allow the passing based on the route list. As can be seen, such solution achieves the anti-passback feature among a plurality of access controllers.

A method for recognizing hand gestures when the hand is held in front of the user's upper body. The method detects dominant features associated with the upper body, including features on the face (eyes and mouth etc.) and the shoulder extremes. Geometrical relations among these features are used to judge whether the face/head has turned to the side relative to the shoulder. If not, a face-shoulder coordinate system is established using these face-shoulder features, and the hand images are transformed into this new coordinate system. This in effect defines hand gestures relative to the user's face and shoulder, thus significantly reducing the dimensions of the feature space for hand gestures. This face-shoulder coordinate transform can be combined either with traditional appearance-based hand gesture recognition methods, or with a conventional or hybrid deep neural network for RGB or RGB-D images.
