Abstract: Computer-implemented methods, non-transitory, computer-readable media, and computer-implemented systems implementing a one-touch login service are described. Information about a first IP address is obtained from a verification request sent by an application client device. A token is sent to the application client device. Information about a second IP address is obtained from a number acquisition request sent by an application server. Whether the first IP address is the same as the second IP address is determined. If the same, based on a token carried in the number acquisition request, a mobile phone number of a terminal device in which the application client device is located is obtained and the mobile phone number is sent to the application server. If not the same, sending the mobile phone number of the terminal device to the application server is refused.

Abstract: A computer-implemented method for communication channel management performed by a wireless access point (AP) device is described. An original management frame that carries a target information element is constructed, where the target information element includes an information element related to communication channel management. When determined that one or more clients are connected to the AP device, for each of the determined clients: A destination address of the original management frame is set to a MAC address of the client. To obtain an encrypted management frame by using a key corresponding to the client, information in the target information element is encrypted. The encrypted management frame is sent in a WiFi network, so that a connected client in the WiFi network determines, based on the destination address, whether to process the encrypted management frame.

Abstract: A coreless permanent motor has a stator and a rotor rotatably mounted to the stator. One of the stator or the rotor has at least one winding disc (28). The other one of the stator or the rotor has at least one surface charged magnet disc (33). The winding disc (28) or the magnet disc (33) is formed by two or more sector shaped units that are mounted to two or more support members (27) respectively. The winding disc (28) or the magnet disc (33) is formed by closing the support member (27) and the closed support members (27) form a cylindrical housing. Thus, the structure of the coreless motor is simplified.
