Abstract: A packet processing method includes, when data at a first location in a packet arrives at a channel forwarding layer, determining a first multiframe used to bear the data at the first location, and determining a real timestamp of the first multiframe based on a timestamp of a second multiframe in a channel in which the first multiframe is located. The second multiframe is an Xth multiframe previous to the first multiframe in the channel, X?0, and the timestamp of the second multiframe is a timestamp at which a second location of the second multiframe arrives at a physical layer such that packet stamping is implemented in the Ethernet leased line technology.

Abstract: A graphics processing unit (GPU)-based numerical simulation system and method for a helicopter flow field (FF). The GPU-based system includes a central processing unit (CPU) and a GPU. The CPU is configured to initialize a moving overset grid according to a preset configuration file and the mesh files of a to-be-simulated helicopter; determine face batch information according to mesh blocks in the moving overset grid; determine an overset interpolation relationship between the mesh blocks and an interpolation mapping index according to the mesh files at a current simulation moment; and perform FF information exchanging between the mesh blocks according to the overset interpolation relationship, the interpolation mapping index, and FF information of the mesh blocks, to obtain to-be-simulated helicopter FF information. The GPU computes the FF information of the mesh blocks in the motion nested mesh according to surface batch information by using a computational fluid dynamics (CFD) method.

Abstract: This application provides an in-vehicle communication method, an apparatus, and a system. The system including: multiple gateways connected through a bus, where an ASN apparatus is disposed in each gateway. The ASN apparatus sends, to one or more of an in-vehicle service node, a controller, data carried in an ATU that is decapsulated by the ASN apparatus, or sends, to another gateway connected to the gateway, an ATU encapsulated by the ASN apparatus; and the ATU is obtained by encapsulating data of each in-vehicle service based on a physical layer coding rule that adapts to the bus; and the in-vehicle service node, the controller, or the in-vehicle networked terminal connected to the gateway, configured to receive decapsulated data sent by the gateway or send, to the gateway, data corresponding to an in-vehicle service of the in-vehicle service node, the controller, or the in-vehicle networked terminal.

Abstract: A helicopter active noise suppression device integrating a sound array and on-propeller control, which relates to the technical field of helicopter noise reduction, includes an annular loudspeaker array, a plurality of force exciters, an error microphone, an Active Noise Cancellation (ANC) controller, a cockpit sensor, and an airborne computer. The annular loudspeaker array is arranged at a rotor hub and unsteady force exciters are arranged at each blade trailing edge to construct a sound field in an reversed phase to the sound wave of an original sound field with an ANC principle, thereby counteracting the noise and realizing the noise reduction of all-domain and all-type helicopter noise.

Abstract: Systems and methods for detecting an analyte include test wands configured to employ immunochromatographic assay with new fluorescent labeling technology, a reading device that can specifically identify signals from wands and sync information to the mobile devices. The systems may quantitatively detect progesterone metabolites in urine to track the level changes, confirm ovulation, and/or evaluate menstruation status. The systems and methods assess and track an individual's ovulation cycle by monitoring a hormone pattern of that specific individual, and establishing a dynamic threshold as a baseline for changes in the specific subject's hormones.

Abstract: A sensing mechanism of a two-dimensional airfoil model, which includes pressure sensor groups, multiple first tubes, the second tube, and a cavity. The pressure sensor groups are vertically fixed to mounting holes in the surface of the two-dimensional airfoil model. The pressure measurement surface of each pressure sensor is vertical to the surface of the two-dimensional airfoil model.

Abstract: A FRP plate and manufacturing method thereof are provided in the invention. The FRP plate comprises: a lower layer of polyester carrier film; a mixed layer located on the lower layer of polyester carrier film, which is formed by curing a melted polyester resin in which a glass fiber reinforced material is embedded; and an upper layer of polyester carrier film positioned on the mixed layer. Furthermore, a release fabric is disposed between the mixed layer and the upper layer of polyester carrier film. When the FRP plate of the invention is used, the upper layer of polyester carrier film and the release fabric are torn off so that the surface of the mixed layer is rough, therefore, the adhesion between the FRP plate and other building materials will be greatly improved, and thus the application prospect of the FRP plate is broader.
