Abstract: An utterer identification device executes: performing voice recognition from input utterance data; selecting, from among a plurality of registered utterance contents set in advance, a registered utterance content closest to a recognized utterance content indicated by a result of the voice recognition as a selected utterance content; selecting, from among a plurality of databases respectively associated with the registered utterance contents, a database associated with the selected utterance content; calculating a similarity between a feature quantity of the input utterance data and a feature quantity stored in the selected database; and identifying a certain utterer on the basis of the similarity, and outputting a result of the identification.

Abstract: A voice recognition device includes an estimation unit that compares a plurality of pieces of registration voice data stored in a database with input voice data uttered by a speaker who gets on a mobile body to estimate a registration command corresponding to the input command, a presentation unit that presents an estimation result, a second acquisition unit that acquires an error instruction indicating that the estimation result is an error, a determination unit that, in a case where the error instruction is acquired, determines a correct command corresponding to the input command based on an operation by the speaker, and a database management unit that stores the correct command and the input voice data in the database in association with each other

Abstract: An object of the present invention is to provide a brake control device and a brake system capable of braking with a shortened braking response when shifting from non-braking to braking. A brake control device 10 includes a command value calculation unit 4 that calculates an operation command value required to make a pressing force by which a brake pad 11a is pressed against a brake disc 11b reach a target thrust value. The command value calculation unit 4 includes: a clearance command calculation unit 43 that calculates a command value required for contact between the brake pad 11a and the brake disc 11b; and a thrust command calculation unit 40 that calculates a command value required for reaching the target thrust from a state where the brake pad 11a and the brake disc 11b are in contact with each other.

Abstract: A voice recognition device includes: a calculation unit that calculates a first feature amount that is a feature amount of input voice data acquired by a first acquisition unit; an estimation unit that estimates a driving situation of a mobile object on the basis of operation information acquired by a second acquisition unit; an extraction unit that extracts, from a feature amount database, a second feature amount corresponding to the driving situation; a recognition unit that recognizes an input command on the basis of similarity between the first feature amount and the second feature amount; and an output unit that outputs a recognition result.

Abstract: Pixels A, B, C, D and E of a reference image X, which are suitable for use in a pattern matching operation, are automatically determined on a pattern of the reference image. The automatic determination of the pixels is done based on a change of brightness at areas around the selected pixels. Coordinates of all of the selected pixels, such as (x.sub.1, y.sub.1), (x.sub.2, y.sub.2), (x.sub.3, y.sub.3), (x.sub.4, y.sub.4) and (x.sub.5, y.sub.5) are stored in memory. A scan of the image to be detected is done at a fixed offset area for each of the selected pixels. The values of the difference in brightness between the selected pixels and the scanned points are accumulated. The minimum value of the accumulated difference is detected, and the coordinate of the scanned point which provides the minimum accumulated difference is determined as a deviation of the detected image from the reference image.

Abstract: An inspection device and method that closely approximates a visual inspection technique for evaluating the quality of a sample. A mask image generation section generates a master image from an image signal of a known good sample. The image signal is used to a first mask image. A plurality of second mask images are generated by magnifying a pattern area of the first mask image by different magnification ratios. A discrimination surface area threshold is set for each mask image. An image under inspection generation section generates a binary image of an unknown sample. A discrimination section takes the logical AND of the binary images of the unknown sample and each mask image, calculates surface areas of pinhole flaws existing in a background area of the binary image under inspection, compares the calculated surface areas and the threshold corresponding to the mask images, and performs a pass/fail judgement of the unknown sample based on the result of this comparison.

Abstract: A cloth feeding apparatus having two feeding devices with respect to the feeding direction and adapted to feed a cloth under a tension by setting the feeding amount on the downstream greater than the feeding amount on the upstream.

Abstract: A cloth feed apparatus to be equipped with a sewing machine, the cloth feed apparatus including a roller driven by means of a stepping motor which is actuated in accordance with electric pulses generated by a detector detecting rotation of a main shaft of the sewing machine, the detector generating electric pulses by detecting slits of disc firmly mounted on a main shaft of the sewing machine.
