Abstract: The present invention relates to a kind of pigment preparation, in particular to a modified layered silicate novel barrier and shielding pigment and its preparation method. It is a layer silicate with exchangeable anticorrosive ions as a template, using metal oxides or metal salts, inorganic acids to synthesize nano-spherical zinc phosphate, phosphate, molybdate, borate or tungstate, with rare earth cerium, strontium, lanthanum or praseodymium doped modification of the pigment. The invention uses silicate as a template to effectively control the agglomeration of nanoparticles during the liquid phase deposition process, avoiding the multiple cleaning and sewage treatment processes required by using surfactants and solvents. What is more valuable is lamellar silicic acid. The salt itself has certain anti-corrosion properties and is economical.

Abstract: In a real-time video transmission system for a cellular-connected unmanned aerial vehicle (UAV) based on an adaptive bitrate provided by the present disclosure, an on-board computer is loaded and configured on the UAV, such that the UAV can provide multiple video streams with different bitrates for retrieval. A client with a bitrate adaptation unit is set up, allowing the system to adjust the bitrate of the video stream according to network conditions in each time interval. Intranet penetration and port mapping are implemented on the cloud server, enabling the client to obtain, from the cloud server, the real-time video stream captured by the UAV. The present disclosure allows a remote user to watch, through a cellular network, the real-time video stream captured by the UAV.

Abstract: An improved garment, preferably for infants, young children and people with disabilities, comprises functionality to detach the garment's legs from the upper portion and expose the pelvic area, wherein a caregiver may easily and efficiently change the wearer's diaper without going through effort to take their legs out from the garment's legs, while also continuing to keep the wearer comfortable by having their legs covered and warm during diaper changes. The garment comprises 2 sections; an upper portion with the bottom having the front panel and rear panel separated from each other, and a pair of legs. The middle part of both the front panel and rear panels of the upper portion are secured via a magnetic closure system. The legs can be connected with the bottom of the upper portion via zippers or other garment closures including, but not limited to, buttons, snap fasteners, and hook and eye fasteners.

Abstract: The present disclosure discloses a method for determining a location of a passenger flow corridor based on card swiping data. The method includes collecting data, obtaining a station passenger flow of a “new road”, determining the location of the passenger flow corridor, testing an accuracy of the location of the passenger flow corridor, and displaying the location of the passenger flow corridor through WebGIS. Basic information such as boarding stations, card swiping time, and affiliated roads can be obtained by stable matching, and then stations can be clustered and rearranged to the new road on which routes and roads are fitted. A largest station passenger flow in a whole region is selected, and a station passenger flow of each road is determined through grade classification, so that the locations of the passenger flow corridors in the whole region are accurately selected.

Abstract: A training mechanism for water-based lower-limb rehabilitation, including two leg training sub-mechanisms. Each leg training sub-mechanism includes a hip joint training device, an adjustable thigh plate, an adjustable shank plate, a knee training device, an ankle training device and a pedal. The hip joint training device, knee training device and ankle training device are connected to a remote control motor box through a Bowden cable assembly, respectively. A robot including the training mechanism is also provided, whose power source is arranged outside the water, and the power is supplied to the training mechanism through the Bowden cable assembly.

Abstract: The present application relates to the technical field of sensors, and in particular, to a flexible piezoresistive sensor and a preparation method thereof. The preparation method includes the following steps: cutting natural wood to obtain wood blocks; removing lignin and hemicellulose from the wood blocks to obtain an initial product; and connecting the initial product to an electrode, and conducting packaging to obtain the flexible piezoresistive sensor. The preparation method has the advantages of a wide range of raw materials, degradability, low cost, simple process, and industrial scale production, and the obtained product features excellent environmental friendliness, biocompatibility, designability, and flexibility, thereby providing a good application potential for a wearable device.

Abstract: Embodiments of this application relate to the field of communications technologies, and disclose a dynamic scheduling method, an apparatus, and a system, so as to reduce information exchange costs and calculation complexity of data scheduling and route allocation. The method includes: receiving, by a scheduling platform, first VOQ length information of each aggregation switch in each timeslot; aggregating all the received first VOQ length information, to obtain global VOQ length information, where the global VOQ length information includes a total quantity of data packets that need to be sent from each of M pods to other pods than the pod; determining a transmission matching scheme based on the global VOQ length information; and sending corresponding matching result information to each aggregation switch according to the transmission matching scheme, so that each aggregation switch sends a data packet according to the transmission matching scheme.

Abstract: A tolerance strip is formed a strip of resilient material with corrugations, the corrugations extending transversely across the full width of the strip, the corrugations defining crests with troughs between adjacent corrugations, a central portion of the corrugations being of substantially uniform height across the strip, portions of the corrugations adjacent each longitudinal edge of the strip decreasing in height towards the edge of the strip. In one form the corrugations are flat longitudinally of the strip at the crests and/or troughs.
