The detection mechanisms are arranged on the frame and located on two sides of the transport mechanism. The grasping mechanism is arranged on the frame and used to transport workpieces on the feeding line to the detection mechanisms, transport qualified workpieces to the first flow line, and transport unqualified workpieces to the second flow line.

Abstract: Embodiments of this application provide methods and apparatuses for offline payment authorization. In an implementation, a method comprising: obtaining wallet account information, a current account balance, and current credit information of a target electronic wallet account in response to determining that a current state of the target electronic wallet account satisfies a predetermined certificate delivery condition, determining an offline payment limit based on the current account balance and the current credit information, signing summary information by using a private key of a server to obtain an electronic wallet signature, generating a user certificate based on the summary information and the electronic wallet signature, and sending the user certificate to a terminal device associated with the target electronic wallet account for an offline account corresponding to the target electronic wallet account to make offline payment within the offline payment limit based on the user certificate.

Abstract: The present disclosure provides a method for recycling urea-formaldehyde (UF) from a wood-based panel. In the present disclosure, the UF is depolymerized by an ultrasonic treatment, and depolymerized UF can be reused for UF manufacture and wood-based panel production. The recycled and treated UF can be repeatedly used in wood-based panel manufacture without affecting performances of the wood-based panel. UF-glued wood-based panels can be recycled, and a recycled wood-based panel raw material can replace at least 50% of a non-recycled wood-based raw material for particle board production without affecting performances of the wood-based panel.

Abstract: Provided is a hybrid modular multilevel converter (HMMC) based on a neutral point clamped (NPC) topology and having an ABC N-phase structure. The HMMC includes N pairs of identical upper and lower arms, each upper and lower arm being composed of X submodules and Y sets of switches. The switches within each set are cascaded and connected in series, each of the submodules is formed of full-bridge silicon (Si) insulated-gate bipolar transistor (IGBT) converters, and at least one of the set of switches is formed of IGBTs of opposite polarities.

Abstract: A ventilation treatment device and a ventilation-control method are provided. During use, when a headband contacts a headrest, a first valve assembly contacts a second valve assembly to open first air holes and second air holes, thereby communicating a first chamber with a second chamber, such that air from an air source into the first chamber enters the second chamber and further enters a respiratory chamber of a patient connecting apparatus for inhalation by a patient; and when the headband is separated from the headrest, the first valve assembly and the second value assembly are separated to close the first air holes and the second air holes, thereby preventing the air in the first chamber and the second chamber from flowing out through the first air holes and the second air holes, respectively.

Abstract: A non-invasive time domain reflection probe calibration method includes: using different volume ratio of ethanol and deionized water mixed solution to calculate a test target's medium weight coefficient and waveguide length of the non-invasive time domain reflection probes; using different concentrations of NaCl solutions to calibrate a waveguide geometric dimensioning of the non-invasive time domain reflection probes; preparing compacted soil samples with known different moisture contents and densities, and calibrating a correlation parameter of compacted soil samples' dielectric constant and conductivity with moisture content and density. The method not only determines the sensitivity of the test target medium of the non-invasive time domain reflection probes, but also obtains the waveguide length and geometric dimensioning of the probe, and realizes an accurate test of moisture content and density of the soil.

The method includes: receiving user input through a user interface, where the user input includes a data type parameter, a value parameter, a generation time parameter and a target interface parameter of data to be generated; searching for a pre-stored data template file corresponding to the data type parameter; generating a data packet queue based on the value parameter by using the data template file; and sending each data packet in the data packet queue to a target interface corresponding to the target interface parameter based on a sending moment specified by the generation time parameter. With this method, the cost of the test system can be reduced and the flexibility of available test data can be improved.
