The invention discloses a mean filtering device for triaxial acceleration data applied to motion detection. The device comprises a motion template database, a filtering controller, an acceleration sensing data collector, an X-axis neighborhood data circular buffer, a Y-axis neighborhood data circular buffer, a Z-axis neighborhood data circular buffer, an X-axis data buffer, a Y-axis data buffer, a Z-axis data buffer, an X-axis mean filter, a Y-axis mean filter and a Z-axis mean filter. According to the idle axial directions of a training template, the filtering functions of corresponding axial directions are turned on or off and each axial neighborhood data circular buffer and each axial data buffer are set; each buffer and each filter are used for mean filtering of data of each axial direction; and thus, high-frequency noise in low-frequency motion signals is effectively filtered out in the process of motion detection under the condition of low consumption of system resources, and the technical problems of incapability of effectively filtering out noise in motion signal and high consumption of system resources in the prior art are overcome.

The invention discloses a numerical-control scanner which comprises a scanning device, a positioning device and a control system, wherein the scanning device can move through a power device and is used for real-time acquisition of axial data of a scanned file; the positioning device is used for positioning and rotating the scanned file and used for real-time acquisition of circumferential data of the scanned file; and the control system is connected with the scanning device and the positioning device and used for collecting and processing the real-time acquisition data of the scanning device and controlling the scanning device to move and the scanned file to rotate. The scanning device is movable, and the positioning device enables the scanned file to rotate axially, so that 360-degree scanning of the scanned file can be achieved during scanning, scanning effects can be guaranteed, and scanned data are processed and stored by the control system to facilitate use for numerical-control mechanical production.

The invention belongs to the field of sport monitoring and relates to a method for monitoring swimming. A gravity sensor of a device of the invention determines different swimming strokes through average value filtering of X, Y and Z axial data, in combination with a judgment formula, and according to the shape and the numerical value of data result. Compared with the prior art, the gaps in swimming detection of sport detection devices are filled up; wearable devices can be addedincluded to add the function of present wearable devices; the method has great market economic value and prospect.

The invention discloses a device for measuring the part concealed portion gap value. The device comprises a handheld base, an end cover, a fixed measuring needle, a movable measuring needle, a radial poking rod, a sliding wedge, a longitudinal push rod and a reading device; the handheld base is internally of a hollow structure, the end cover is installed at one end of the handheld base, a fixed measuring needle base and a movable measuring needle base are arranged on the upper portion of the end cover, the fixed measuring needle is arranged on the fixed measuring needle base, the movable measuring needle is arranged on the movable measuring needle base, and the movable measuring needle base penetrates through a transverse sliding groove formed in the and abuts against the inclined face at one end of the sliding wedge located in the handheld base; the radial poking rod penetrates through the handheld base and the movable measuring needle base on the lower portion of the end cover in the radial direction; the reading device is arranged in the other end of the handheld base, and the longitudinal push rod is arranged between the other end of the sliding wedge and the reading device. By adopting the fixed measuring needle, the movable measuring needle and the longitudinal push rod moving in the axial direction, the data obtained through transverse measurement is converted into axial data to be displayed, and then the part gap value is measured.
