An on-board vehicle occupant weighing technology includes a simplified vehicle occupant weighing apparatus based on the discovered horwest effect and weighing moderator. The simplified weighing apparatus utilizes a weighing unit connected to the car seat of the vehicle occupant and a further weighing moderator, which provides convenient weighing of the foot part of the occupant's body by the same weighing unit that is connected to the car seat. The technology employs several methods of the weight measurements provided by different moderator approaches. The technology, methods, and simplified weighing apparatus are employed in on-board vehicle overweight and obesity preventing system wherein a weight trend analyzer provides predicting possibility of the occupant's overweight or obesity in a short predetermined period of time and automatically warning a vehicle occupant and a health care provider of the condition. The technology may also provide an accurate and convenient occupant's weight measurement in the vehicle safety devices such as seat belt and air bag Supplemental Restraint System (SRS system) to improve the Occupant Classification System to prevent possible extra force applied to the occupant's body in case of collision.

The invention discloses an automatic meteorological station data quality control method based on the empirical mode decomposition. The empirical mode decomposition is used for the automatic meteorological station data quality control. The method comprises the following steps: firstly, collecting single-station data; then, after the collected data is subjected to basic quality control, carrying out EEMD decomposition to obtain an eigenmode component and a trend term; further carrying out weighted approach to the eigenmode component and the trend term; obtaining a weighted eigenmode component and a weighted trend term; and finally, carrying out data reconstruction to the weighted eigenmode component and the weighted trend term so as to obtain denoised data and finish the denoising process. According to the method, on the basis of the basic quality control method, the defect that random noise, system noise, microclimate noise and big noise can not be eliminated with the traditional quality control method is made up, and the quality of the data observation of the automatic meteorological station is improved.

The invention relates to a composite material which is used to manufacture automobile bottom deflectors; the composite material consists of UP resin P171-903B, flexible resin P193-01, fiber glass, low profile additive H814-902, styrene, BYK996, 501 anti-oxidant, heavy calcium carbonate, PBTB, MgO, conductive carbon black powder, Al(OH)3 and zinc stearate. The density of the prepared automobile bottom deflector is 1.8, which meets the light-weighted trend of the prior automobile; the deflector plays the roles of buffering and protecting the passenger carriage; meanwhile, the strength-to-weight ratio (the ratio of ultimate tensile strength to density) is higher than that of metal; the corrosion resistance in adverse environment is excellent, the size is precise, the stability is stable and good strength is kept in a wide temperature range; the inflaming retarding and aging resistance are excellent.

The invention discloses an electric drawing type field tillage method and system. Electric energy is adopted as power, an electric winch and steel wire ropes are utilized to draw a tillage machine to complete agricultural production through fixing facilities and control facilities pre-arranged in the field. According to the electric drawing type field tillage method and system, the electric energy is adopted as driving force of the tillage machine and is emission-free and pollution-free and the environmental requirements of low carbon and emission reduction are met; the electric winch is utilized to replace a cumbersome internal combustion machine, so that light-weight trend of the tillage machine is realized, and a large quantity of materials and power can be saved; the tillage width of the tillage machine can be increased, the operation speed of the tillage machine is increased, and the tillage efficiency is improved; pressure of the tillage machine on soil is reduced, the soil structure is improved, and conservation of water and soil is facilitated; row spacing of crops is shortened, rational close planting is realized, the land use efficiency is improved, and crop yield is increased; the automation level of the tillage machine is improved and the tillage efficiency is improved; the energy consumption is low, the cost of electric energy is low, the tillage price is low, and the tillage cost can be greatly reduced.
