  • Patent number: 11428625
    Abstract: The invention disclosed a friction coefficient measuring device under the condition of material periodic deformation. The measuring device is mainly composed of a torque sensor, a sleeve system, an upper sample, a lower sample, a flexible fixture, an air bearing, a clamping system, a tension-compression sensor, a support rod, and a support table. A working module of a friction-wear testing machine is connected with the torque sensor and then connected with the sleeve system to fix the upper sample. A rotating module of the friction-wear testing machine is used for connecting the flexible fixture to fix the lower sample. The tension-compression sensor can accurately measure the radial force between the upper sample and the lower sample. The torque sensor can measure the load torque values of the upper sample and lower sample during testing.

  • Publication number: 20220222945
    Abstract: A method of calculating a size of a Gaussian kernel in a crowd counting system. The method includes dividing a crowd density map into several areas at equal intervals; calculating an estimated value of average distance of k nearest heads with respect to a head center point coordinate of a current person; calculating a weight coefficient for an average distance of k nearest heads; calculating a size of a Gaussian kernel corresponding to the head center point coordinate of the current person; determining whether there are any head center point coordinates of which sizes of Gaussian kernels have not been calculated yet in training data. If there are head center point coordinates of which sizes of the Gaussian kernels have not been calculated in the training data, recalculating an estimated value of average distance of k nearest heads with respect to another head center point coordinate of another current person.
