The application discloses a non-orthogonal transducer array three-dimensional ultrasonic wind speed and direction instrument which can be carried on a unmanned aerial vehicle and applied to the field of wind speed and direction instruments, and the non-orthogonal transducer array is adopted to reduce the influence of turbulence on wind measurement accuracy; when the turbulence degree generated by one group of transducers is relatively large, the other two groups of transducers can compensate the data, so that high-precision wind speed and direction measurement is realized; meanwhile, when the unmanned aerial vehicle encounters strong wind, the probe fixing rod will be broken, so that the unmanned aerial vehicle is prevented from losing control due to the large wind area of the orthogonal annular support, and the fixed base plate and the elastic thin rod are arranged to recycle the broken and fallen orthogonal annular support and ultrasonic probe, so that the high-altitude falling object is not easy to form, and the orthogonal annular support and the ultrasonic probe are effectively protected, the subsequent recycling and reuse of the orthogonal annular support and the ultrasonic probe are facilitated, and the wind direction and speed detection in strong convection weather such as strong wind is applicable.

The utility model discloses a cutting device for breathable film production, and relates to the technical field of breathable film production, the cutting device comprises an L-shaped pneumatic machine body, a placing support leg and a placing bottom plate, the L-shaped pneumatic machine body is installed and connected on the upper end position of the placing bottom plate, the placing support leg is arranged at the lower end of the placing bottom plate, and the placing support leg is connected with the L-shaped pneumatic machine body. A front-back linear lead screw guide rail module is arranged in the middle of the upper end of the L-shaped pneumatic machine body. A breathable film workpiece is adsorbed through the left pneumatic adsorption plate, the breathable film workpiece is tightened due to external traction and then is adsorbed by the right pneumatic adsorption plate, and then the left and right pressing fixers and the left and right pneumatic adsorption plates are closed together, so that the tightened breathable film workpiece can be effectively pressed; in this way, a breathable film workpiece between the two pneumatic adsorption plates can be in a tightened state, when the front-back linear lead screw guide rail module drives the telescopic cutting mechanism to move front and back, effective cutting can be achieved, and due to the tightened state, cutting is more convenient.

The present invention provides a sole contact body for footwear such as a shoe, an athletic shoe, or a sandal. The sole contact body comprises a raised part which is configured to contact each of the second, third and fourth toes to lift the metatarsophalangeal and proximal interphalangeal joint positions thereof, and which is configured to fit between the first and fifth toes so as not to lift the first and fifth toes throughout the entire lengths thereof. The raised part is configured to have a first toe-side stepped surface that touches the side of the first toe closer to the tip of the first toe than the metatarsophalangeal joint position thereof, and a fifth toe-side stepped surface that touches the side of the fifth toe closer to the tip of the fifth toe than the metatarsophalangeal joint position thereof.
