Abstract: An inflatable product includes an integrated axial-flow pump which produces a high rate of inflation. The pump includes a cover mounted to a body of the pump and selectively configurable between open and closed positions. In the open position, air is allowed to flow between the inflatable chamber and the ambient air through the pump body. When the cover is closed, the air chamber of the inflatable product is sealed with respect to the ambient air such that air is retained within the inflatable chamber when inflated. A power switch is positioned to be deactivated by the cover when the cover is mounted to the body of the pump, such that replacement of the cover during inflation or deflation of the inflatable product automatically deactivates the pump.

Abstract: One aspect provides a system and method for provisioning an access point (AP) in a wireless mesh network. During operation, a controller can obtain a set of published global encryption parameters comprising a master public key, apply an identity-based encryption (IBE) scheme to encrypt a configuration message based at least on the master public key, and transmit the encrypted configuration message to a proxy device, which forwards the encrypted configuration message to the AP. The proxy device is coupled to the controller via a previously established secure communication channel and coupled to the AP via an open communication channel. The AP can decrypt the encrypted configuration message using an AP-specific secret key generated based on a unique identifier of the AP and a master private key corresponding to the master public key, thereby facilitating provisioning of the AP based on the configuration message.

Abstract: The present application proposes a method and a system for constructing a data command frame for remote reservation control, by setting a first byte representing a reserved working time start point, a second byte representing one-time working duration, a third byte representing the reservation status of a whole working cycle, the whole working cycle is divided into several time units, the third byte includes several bits corresponding to several time units, and assigns the value of each bit to determine whether the time units corresponding to each bit is reserved as working time; then combining the first byte, the second byte and the third byte to construct data command frame, and sending the command frames to device to realize remote control. This method enables remote reservation setting on the management of places like spa pools, which is safer and more convenient for spa management staff, and can greatly improve working efficiency and reduce the probability of error.
