Abstract: This application provides an electrical element, a circuit board, and a switching power supply. The electrical element includes a first magnetic core and a second magnetic core disposed opposite to each other. The first magnetic core and the second magnetic core enclose space for accommodating a winding. The first magnetic core and the second magnetic core are further configured to bind a magnetic induction wire. The electrical element further includes a third magnetic core located in the space enclosed by the first magnetic core and the second magnetic core. The third magnetic core is configured to wind the winding. The third magnetic core is fixedly connected to the first magnetic core and the second magnetic core. An air gap is disposed in at least one of the first magnetic core and/or the second magnetic core.

Abstract: A map building apparatus includes a memory storing instructions, and a processor executing the instructions to obtain a plurality of frames of images that carry image information of a target environment, obtain a motion parameter of the image capture component at a capture location of each frame of the plurality of frames of images, obtain a relative displacement between capture locations of each two frames of images based on the motion parameter of the image capture component, obtain, based on the plurality of frames of images and the relative displacement, a map layer including feature points in the plurality of frames of images, and send the map layer and the relative displacement to a server. The plurality of frames of images are captured by an image capture component. The motion parameter indicates a motion status of the image capture component. The map layer is useable to build a map.

Abstract: Embodiments relate to a resource scheduling method, a base station, a scheduler, a program source server, and a system. A method includes receiving, a session start request message comprising carries an SAI corresponding to a program source from a program source server; sending the session start request message to a base station corresponding to the SAI; receiving a session start response message from the base station; adding the base station to an IP multicast group; sending a resource scheduling message comprising information about a MA resource allocated to the program source to the base station; and receiving a resource scheduling response message from the base station.
