The invention relates to an adjustable foot-shaped scanner. The technical scheme is that the adjustable foot-shaped scanner comprises a shell part, a scanner rotating part, a scanner machine head and a controller part, wherein the shell part is provided with a sectional foot support part and a heel height adjusting part; the outer side of the shell part is connected with the scanner machine head through the scanner rotating part so as to rotationally scan the sectional foot support part. According to the adjustable foot-shaped scanner disclosed by the invention, foot shapes, especially, deformation generated under the situation that the body weight is borne by feet, in various status can be scanned, so that scanned foot shape data accord more with an actual situation; compared with a common scanner and a foot-shaped scanner which can just stand horizontally, the adjustable foot-shaped scanner has the obvious advantage in respect of obtaining foot shape data; reliable data are provided for subsequently utilizing the foot shape data, convenience is provided for development design and manufacturing of shoemaking industry, and more reliable data reference can be provided for the fields of medical foot shape correction, man-machine engineering foot shape statistics, human body foot research and the like.

The invention relates to a method for calculating pressure of passive lateral rocks for jointed rocks on an outwardly-inclined bedding slope, pertaining to the technical field of rock pressure analyses in rock and soil mechanics. The method comprises following steps: dispersing bedding joint rocks based on joint surfaces into rigid rocks in a definite number by taking jointed rocks on the outwardly-inclined bedding slope as an object of study; taking pressure of passive lateral rocks as an objective function and shearing force and normal force of joint surfaces as unknown quantities based on a Pan Jiazheng maximum principle to create an equilibrium equation satisfying damaged rocks, yield conditions of joint surfaces, and yield conditions of contact surfaces for rocks and supporting structures; and solving them to obtain the maximum limit value for passive lateral rocks for jointed rocks the an outwardly-inclined bedding slope. The method for calculating pressure of passive lateral rocks for jointed rocks on the outwardly-inclined bedding slope has following beneficial effects: the method is accurate in concept, high in calculation precision, and easy and convenient in engineering application and can be applied to design of structures for retaining walls on jointed rock slopes, slide-resistant piles and pile-anchor supports.

The invention belongs to the technical field of medical devices, and discloses a minimally invasive scalpel for urology and a control method thereof. The right end of the telescopic handle is welded with a hollow strut, the right end of the hollow strut is welded with a support rod, and the upper end of the support rod is fixed with an ellipse Toggle bumps, ellipse toggle bumps are embedded with a camera, the lower end of the support rod is connected to the disc knife through a connecting rod; the telescopic handle is provided with a telescopic outer cylinder, and the telescopic outer cylinder is sleeved with a telescopic inner rod, and the telescopic outer cylinder A through hole is opened on the top, a groove is arranged on the telescopic inner rod, the bottom of the groove is connected with the clamping block through a spring, and the clamping block is clamped in the through hole. The present invention is equipped with a telescopic handle, which can adjust the length of the telescopic handle according to the size of the doctor's palm, which is convenient for grasping the handle and improves the stability of operation; , to detect the magnitude of the current on the wire, and provide reliable data reference for burning and cutting lesion tissue.

The invention discloses a method and equipment for monitoring fall damage of farm houses in an earthquake stricken area. The method comprises the following steps of identifying house structures of the farm houses according to remote-sensing images before the disaster; dividing the farm houses with the same house structure in the same seismic intensity area into the same block; interpreting remote-sensing images after the disaster and determining a first ratio of the farm houses of different damage types in each block according to an interpreted result; determining a second ratio of the farm houses of different damage types in each block according to survey data of a disaster scene; and determining a final ratio of the farm houses of different damage types in each block according to the first ratio and the second ratio. According to the method and the equipment, the damage condition of the farm houses in the disaster area can be more objectively and accurately mastered, and the damage condition of the farm houses in the whole disaster area can be mastered by utilizing the incomplete remote-sensing data especially under the condition that the remote-sensing data cannot cover the whole disaster area.
