A laser scanning system for generating a laser scanning pattern in a scanning field, while amplifying the scan-angle multiplication factor of rotating mirrors employed therein. The laser scanning system employs rotatable laser scanning assembly having an axis of rotation and first and second rotating mirrors with normal vectors that are coplanar with each other and said rotational axis, and which form an acute angle substantially less than 90 degrees so as to provide a laser scanning assembly with a scan angle multiplication factor that is greater than 2.0. A cluster of stationary mirrors mounted about the first and second rotating mirrors, for sweeping a laser beam off the cluster of stationary mirrors after a laser beam has been reflected off the first rotating mirror, then reflected off the second rotating mirror, and then directed outwardly towards an array of pattern mirrors, so as to generate a resultant laser scanning pattern within the scanning field.

The present invention provides a method and apparatus to improve seed distribution to a plurality of seed or row units of an agricultural planter. Each row unit is fitted with a seed box having an air / seed inlet and an air outlet through which air is allowed to escape. The present invention effectively closes off or substantially reduces the flow of air out of one or more of the seed boxes to reduce the amount of seed that is fed to the seed boxes. Through the use of restrictor plates, which may be vented to allow some air flow or solid to prevent air flow, the delivery of seed to the seed boxes can be equalized to provide more uniform seed distribution to the row units.

An embodiment of the invention discloses a calibration method and a calibration device on the basis of POS (position and orientation system) equipment and digital aerial survey cameras, and relates tomeasurement and remote sensing technologies. The calibration method on the basis of the POS equipment and the digital aerial survey cameras includes converting attitude information recorded by the POS equipment to obtain image direct geographic positioning exterior orientation element initial values, acquiring exterior orientation elements by the aid of single-chip resection processes and solvingthe exterior orientation elements; checking obtained multi-sensor data by the aid of position and attitude parameters on the basis of the POS equipment and auxiliary aerial triangulation exterior orientation element interaction verification processes on the basis of GPS (global positioning system) equipment; carrying out absolute orientation by the aid of the image direct geographic positioning exterior orientation element initial values and control points directly, uniformly acquiring field checking points of calibration fields and carrying out calibration. The exterior orientation elementsare used as true values. The calibration method and the calibration device have the advantages that system integration errors can be effectively calibrated by the aid of the calibration method and calibration device; the calibration method and the calibration device are applicable to calibrating the exterior orientation elements.

Disclosed herein is a simulated moving bed for a chromatography device in the technical field of physical separation, comprising a stationary pipe with a plurality of inlet / outlet channels, a rotary device connected to the stationary pipe, a stationary segmented vessel that communicates with the rotary device, a fluid moving device to circulate the fluid, and a driver to rotate the rotary device for a fixed angle, wherein the one end of the rotational flow distribution channel of the rotary device communicates with the corresponding stationary inlet / outlet channel, and the other end communicates with the next corresponding stationary flow distribution segment of the stationary segmented vessel. The invention combines the advantages for radial flow and rotary valve, and the stationary phase filler and the fluid mobile phase can simulate relative motion by adding a fluid driving device and improving partition plates in different regions or communicating specific fluid transfer regions via pipes. The continuous chromatography is separated and changed to a simulated moving bed chromatography so as to enhance the stationary phase utilization and reduce the solvent consumption.
