A gate apparatus () includes an imaging unit () that images a person passing through a passage leading to a gate, an acquisition unit () that acquires a detection result from a detection unit which is provided on a floor of the passage, and a control unit () that controls, by using the detection result acquired by the acquisition unit (), imaging timing of an imaging unit ().

Gate system, gate apparatus, control method therefor, and program

A vibration measurement apparatusincludes a detection unitthat acquires, as a pattern image from an image capturing apparatusthat shoots a measurement target surface of a structure, an image of the measurement target surface onto which pattern light is projected by an optical apparatus, and detects the pattern light from the pattern image, an estimation unitthat estimates an angle between the normal of the image capturing surface and the normal of the measurement target surface, based on the pattern light, an image conversion unitthat converts the shot image into an image that would be obtained were the normal of the measurement target surface coincident with the normal of the image capturing surface of the image capturing apparatus, using the estimated angle, and a vibration measurement unitthat measures the vibration of the structureusing the converted image.

Measurement system, correction processing apparatus, correction processing method, and computer-readable recording medium

A vibration measurement system comprises an image capturing apparatus, a distance measuring apparatus, a sensor that outputs a signal according to an inclination of the image capturing apparatus relative to the vertical direction, and a vibration measurement apparatus. The vibration measurement apparatus includes calculating an angle formed by the normal of an image capturing surface of the image capturing apparatus and the normal of the measurement target surface that the image capturing apparatus shoots, based on the signal output by the sensor, converting the image obtained that the image capturing apparatus shoots into an image that would be obtained were the normal of the measurement target surface coincident with the normal of the image capturing surface of the image capturing apparatus, using the calculated angle, and measuring vibration of the structure, using the converted image and the measured distance from the image capturing apparatus to the measurement target surface.

An information presentation device transmits information of a car navigation system, installed in a vehicle, to a driver in form of tactile stimuli, wherein a controller controls a plurality of vibrators attached to a steering wheel. The vibrators are arranged in proximity to vibration transmitters, corresponding to holding parts of a steering wheel, so that they are controlled with desired vibration intensity and vibration start timing in response to drive signals from the controller. Two vibrators are arranged in the holding parts of a steering wheel which come in contact with driver's hands and are controlled to generate a virtual vibrating source, thus rendering a driver feeling a sensation as if a vibrating source is moving in upward-downward directions, left-right directions, and far-near directions in the front side of a driver. Thus, it is possible to present accurate information with a small amount of energy consumption in driving vibrators.

Information presentation device using tactile stimulus with vibrator

A pump chamber () is formed between a piezoelectric vibrator () and a valve main plate (). The valve main plate () includes an inlet port () at its central portion, and an outlet port () in its peripheral portion, and the inlet port () is made in a smaller diameter than the outlet port (). On the valve main plate () an inflow check valve () and an outflow check valve () are provided, so that when the inflow check valve () and the outflow check valve () open and close in response to the vibration of the piezoelectric vibrator (), a fluid is introduced into and discharged from the pump chamber ().
