Abstract: Example control methods and apparatus are described. An example control method for an uninterruptible power supply system includes: when a bypass power supply branch supplies power to a load, outputting a first drive signal to a first switch device and outputting a second drive signal to a second switch device; and controlling the first drive signal and the second drive signal to have a phase difference with an input voltage of the bypass power supply branch; or when a load current of the bypass power supply branch is less than a first threshold, outputting an inverter control signal to control an inverter power supply branch to charge an energy storage battery; or when a current of the inverter power supply branch flows back to an input end of the bypass power supply branch, turning off the first switch device and the second switch device via the inverter power supply branch.

Abstract: Provided is an automatic air-release box lid, including: a box lid body provided with an air hole, the air hole being configured as a through-hole structure, openings at two ends of the air hole being located on an upper surface and a lower surface of the box lid body respectively; and a fastening lug having a rotating shaft part by which the fastening lug is hinged to the upper surface of the box lid body, the rotating shaft part and one opening of the air hole being arranged corresponding to each other and one above the other, the rotating shaft part having a blocking surface. Further provided is a preservation box, including: an automatic air-release box lid and a box body. The box lid is fitted to cover the box body.

Abstract: This document relates to methods and materials involved in treating cancer. For example, methods and materials for using one or more oncolytic viruses (e.g., one or more replicating oncolytic viruses) to treat cancer in a mammal (e.g., a human) identified as having a cancer likely to respond to oncolytic virotherapy are provided.

Abstract: Disclosed herein are low density fiber cement articles, such as fiber cement building panels and sheets, comprised of multiple overlaying fiber cement substrate layers having small and uniform entrained air pockets and low density fillers distributed throughout. The combination of entrained air pockets and low density fillers provide a low density fiber cement matrix with physical and mechanical properties similar to comparable low density fiber cement matrix without entrained air pockets.

Abstract: Disclosed herein are low density fiber cement articles, such as fiber cement building panels and sheets, comprised of multiple overlaying fiber cement substrate layers having small and uniform entrained air pockets distributed throughout. Also disclosed herein are air entrainment systems and methods for manufacturing aerated low density fiber cement panels or sheets with consistent air void content and uniform air void distribution. Also disclosed herein are air entrainment technologies adapted to work in conjunction with the Hatschek process to produce aerated fiber cement articles having controlled air void content and distribution.

Abstract: An external storage device includes a storage unit, a D flip-flop, a power supply, an interface unit, and a processing unit. The interface unit receives an out-of-band (OOB) signal from a host computer and transmits the OOB signal to a clock input terminal of the D flip-flop. The processing unit transmits a reset signal to a data input terminal of the D flip-flop. When the processing unit detects that an output value on a output terminal of the D flip-flop changes, the processing unit controls the power supply to provide power to the storage unit. A method for starting up an external storage device is also provided.

Abstract: A high-accuracy oscillator obtains initial control bits to generate an initial signal and generates adjacent control bits to generate an adjusted signal from the oscillator based on the adjacent control bits. Characteristics of the initial signal and the adjacent signal are compared to a preset value to determine which of the initial signal and the adjusted signal is closer to a target signal. The closer of the initial signal and the adjusted signal to the target signal is output from the oscillator.
