摘要： A sound wave sensor, capable of reliably detecting presence or absence of a banknote very easily with use of sound waves, is provided. The sound wave sensor includes a sounding body 2 that outputs a sound wave signal of a predetermined frequency, an echo body 3 opposed to the sounding body 2 in a direction in which the sounding body 2 outputs the sound wave signal, the echo body 3 being provided at a position where the sound wave signal resonates at the predetermined frequency; a slit 5 through which a sheet-like banknote 4 passes, the slit 5 being provided between the sounding body 2 and the echo body 3; and a resonance determination unit 6 that determines a resonant state of the frequency output from the sounding body 2. The resonance determination unit 6 determines a resonant state by detecting variation in power consumption of the sounding body 2.

摘要： An image recognition device includes: an image processing device that acquires a feature amount from an image; and an identification device that determines whether a prescribed identification object is present in the image, and identifies the identification object. The identification device includes a BNN that has learned the identification object in advance, and performs identification processing by performing a binary calculation with the BNN on the feature amount acquired by the image processing device. Then, the identification device selects a portion effective for identification from among high-dimensional feature amounts output by the image processing device to reduce the dimensions used in identification processing, and copies low-dimensional feature amounts output by the image processing device to increase dimensions.

摘要： An image processing device converts an image that is a recognition object image to high-resolution, medium-resolution, and low-resolution images. The device sets the pixel of interest of the high-resolution image, and votes the co-occurrence in a gradient direction with offset pixels, the co-occurrence in the gradient direction pixels in the medium-resolution image, and the co-occurrence in the gradient direction pixels in the low-resolution image, to a co-occurrence matrix. The device creates such a co-occurrence matrix for each pixel combination and for each resolution. The device executes the process on each of the pixels of the high-resolution image, and creates a co-occurrence histogram wherein the elements of a plurality of co-occurrence matrices are arranged in a line. The device normalizes the co-occurrence histogram and extracts, as a feature quantity of the image, a vector quantity having as a component a frequency resulting from the normalization.

摘要： A mobile capsule device 10 comprises a long capsule body 11 having a permanent magnet 13 movable in the lengthwise direction with respect to the long capsule body and a coil for driving the permanent magnet 13, while a propulsion force is generated entirely by applying an alternate current to the coil and performing back and forth movements of the permanent magnet 13. The coil has first and second coil parts 15 and 16 arranged circumferentially in front and back of the permanent magnet 13, and a frequency of an alternate current applied to the first and second coil parts 15 and 16 is made to accord with a resonance frequency of the capsule device 10 generated by a back and forth vibration of the permanent magnet 13. Thereby, a self-propelled, mobile capsule device 10 which is downsized, compact and efficient and a control method thereof can be provided.
