Horizontal axle windmill and method for making wind-powered unit vane

Disclosed are a horizontal axis windmill and a manufacturing method for the vane of the wind turbines. The windmill comprises a tower and a wind wheel hub which is provided with vanes, wherein the vanes have structures for designing bending and torsional deforms in advance and structures for designing the prestress at the root of the vane in advance. The method is that the connection line of each section center of the vane is bent or inclined forward from the root to the top, so the vane can keep at straight status from root to top when the windmill is in running; the torsional angle of the aerofoil profile on each section of the vane is designed along the radial direction, the torsional deformation of the vane can be obtained according to the pneumatic load distribution of the vane, and the reverse torsional deform angle of the aerofoil profile on each section is designed in advance to make the torsional angle when the vane is running consistent to the designed geometry torsional angle of the vane; and the root of the vane has stress. When the vanes of the windmill are working, the vanes are basically at radial direction, the inflow flush angle and designed working condition of all the sections are basically consistent, the high efficiency use of wind energy is realized, the root stress of the vane is reduced, and the safety of the vane is improved.

Method, brace and system for measuring torsion or bending of a part of a human or animal body

Method, brace (55), and system for measuring a degree of torsion or bending of a part of a human or animal body. The method comprises the steps of attaching a sensor (56) to a part of the human or animal body, obtaining calibration data of the sensor by detecting the output signal of the sensor for a well defined degree of torsion or bending of said part of the human or animal body, storing the calibration data, measuring an output signal of the sensor during torsion or bending of said part of the human or animal body, and a final step of relating said output signal of the sensor to a degree of torsion or bending by using the calibration data. The method, brace and system are characterised in that the sensor comprises an electrically conductive loop (51), the area of said loop at least partially covering said part of the human or animal body, for instance a knee, and that the sensor further comprises an output unit (57) for providing an output signal that is a measure for the inductance of the loop.

Preparation method of ultraviolet detector based on ZnO micro-wire array embedded in flexible substrate

The invention discloses a preparation method of an ultraviolet detector based on a ZnO micro-wire array embedded in a flexible substrate. The method comprises the following steps: preparing ZnO micro-wires from zinc powder evenly placed on a quartz boat and a quartz tube as raw materials with a chemical vapor deposition method; then, transferring the prepared ZnO micro-wires to a cleaned glass substrate, arranging the micro-wires orderly, adding dropwise PVAL glue to cover surfaces of the ZnO micro-wires, and removing the ZnO micro-wires and a PVAL substrate from the glass substrate after theglue is solidified to complete embedding of an ZnO micro-wire array into the flexible substrate; next, depositing gold interdigital electrodes on the surface of the ZnO micro-wire array to complete preparation of the ultraviolet detector based on the ZnO micro-wire array. According to the method, the PVAL flexible substrate is used, and the ZnO micro-wire array can be protected to the greatest extent and forms the best contact with the electrodes, so that the detector is highly integrated.
