Abstract: Systems and methods of managing a Bluetooth SigMesh network involve a supervisor configured to monitor one or more network parameters of the SigMesh network, such as topology, message identity, transmit count, transmit interval, relay retransmit count, or relay retransmit interval. The supervisor determines whether one or more of the network parameters are to be adjusted for improving transmission efficiency, reducing traffic congestion, avoiding flooding of packets on the mesh network, or ensuring injection of packets in the SigMesh network. The supervisor provides feedback to one or more nodes with the adjusted network parameters to improve transmission efficiency and reduce traffic in the SigMesh network.

Abstract: A dual pre-stacking system of steel plates for a single cutting line and a stacking method therefor. The dual pre-stacking system comprises: a cooling bed inspection stand, a crop shear with a cut-to-length function, a bilateral shear, 1# inkjet printer, a front pre-stacker, a cut-to-length shear, a length and thickness gauge, 2# inkjet printer, surface check/size inspection and fitting, and a rear pre-stacker arranged in order along the roller.

Abstract: An instant heating smart milk maker includes a body, and a powdered milk charge metering device, a powdered milk brewing device, a water tank, a hot water supply device, a control circuit board, and a powdered milk feeder drive device mounted on the body. The hot water supply device and the powdered milk feeder drive device are electrically connected to the control circuit board. The powdered milk charge metering device includes a driving shaft, a powdered milk supply impeller and a powdered milk box. The powdered milk supply impeller is connected to the powdered milk feeder drive device in a transmission way through the driving shaft. An powdered milk inlet of the powdered milk brewing device is connected to a powdered milk outlet of the powdered milk box. The water tank is connected to a water inlet of the hot water supply device.

Abstract: Disclosed are a method for unlocking a screen and a system for installing a screen. It is determined whether to unlock the screen by calculating an angle between a starting position and a current position of a touch point on the screen with the unlocking reference point as a vertex of the angle. With a technical solution of the disclosure, no path or destination position for screen unlocking is defined, with more casual operation, enhanced user experience, and simpler setting, thereby facilitating usage. Moreover, unlocking by mistake can also be prevented by the setting.

Abstract: The present document provides an information synchronization method, apparatus and communication terminal based on a personal information management system. A user data server at a network side stores status information of a first user and copies the status information of the first user to a name card of the first user stored by a second user in a PIM server; and the PIM server synchronizes the status information of the first user in the name card of the first user to a communication terminal of the second user. The scheme described above enables different specific users to acquire or query specific information of the other party by a communication terminal such as mobile phone.

Abstract: The present document provides a method for simulating left key input and right key input using a capacitive screen stylus, which is applied to a terminal provided with a capacitive screen. The method includes: after receiving a command of a user selecting to perform left key input or right key input, the capacitive screen stylus outputting an electric signal corresponding to the command; and the terminal, if determining that the capacitive screen receives the electric signal through contact with the capacitive screen stylus, executing the input command of the user according to an input mode corresponding to the electric signal. The technical problem of being unable to perform the left key input and right key input conveniently in the related art is solved.

Abstract: A high-voltage-resistant rectifier with standard CMOS transistors is disclosed in present invention. In a bridge full-wave rectifier comprising four MOS transistors, extra transistors are connected in series between the transistors which endure high voltage and the input to decrease the voltage imposed on the gate of them; moreover, the present invention provides a way to divide voltage imposed between the gate and the source of the said transistors by connecting in series with extra transistors, so it is achieved to implement a high-voltage-resistant rectifier with standard low voltage CMOS transistors without additional process complexity, and decreases manufacture and process costs.
