Abstract: A bubble machine with an adjustable blowing angle comprises a machine body, an air supply mechanism arranged inside the machine body, and a film forming mechanism, wherein the air supply mechanism comprises a double-shaft motor, a fan cover arranged outside the double-shaft motor, and the film forming mechanism comprises a rotary table, a plurality of bubble rings uniformly arranged on the circumference of the rotary table, and a liquid storage tank arranged below the rotary table; one output shaft of the double-shaft motor is provided with a fan blade, and the other output shaft of the double-shaft motor drives the rotary table to rotate after being decelerated by a gear box; the bubble rings are arranged along the normal of the rotary table, and the fan cover is provided with a rotatable air duct at the position of the air outlet; the bubble rings are arranged along the normal of the rotary table, and then the air flow is output to the bubble rings through the action of the air duct.

Abstract: A method is performed by a first access point (AP) of a plurality of access points (APs). The first AP includes a non-transitory memory and one or more processors coupled with the non-transitory memory. In some implementations, the method includes determining traffic information for a first set of client devices that are being served by the first AP. In some implementations, the method includes obtaining traffic information for a second set of client devices that are being served by a second AP of the plurality of APs. In some implementations, the method includes synthesizing a unified traffic indicator map (TIM) based on the traffic information for the first set of client devices and the traffic information for the second set of client devices. In some implementations, the method includes transmitting the unified TIM to the plurality of APs. In some implementations, the unified TIM satisfies a network performance criterion.

Abstract: A wireless network system that provides for seamless roaming of client devices is described. The wireless network system includes a plurality of access points. One access point is designated as the primary access point that is responsible for handling encrypted communication with the client device. The primary access point has access to the necessary encryption key(s) for encrypted communication. The primary access point receives broadcast updates from the other access points that includes connection scores. When a connection score for a second access point exceeds the connection score of the current primary access point, the current primary access point designates the second access point as the new primary access point and sends the new primary access point the encryption key(s) for encrypted communication. The handoff is seamless and does not require a new handshake between the new primary access point and the client device.

Abstract: In one implementation, a wireless network device is automatically accessed and configured through a mobile device. The mobile device receives provisioning data encoded for installation and operation of a network device and decodes the provisioning data to identify at least one access parameter for the network device. The mobile device accesses a wireless network of the network device according to the access parameter. Once access has been established, the mobile device transmits a configuration signal including a network configuration setting through the wireless network to the network device for the installation of the network device. The network device is provisioned based on the network configuration setting.
