An image capturing unit captures an image of a surface of a member treated by a surface treatment unit. A comparison unit obtains a correlation coefficient between a reference image stored in a storage unit and the image captured by the image capturing unit. A cross-correlation coefficient between power spectra of the reference image and the image captured by the image capturing unit is obtained. A control unit stops a surface treatment performed by the surface treatment unit when the correlation coefficient obtained by the comparison unit reaches a set value.

A tactile sensation presentation device includes a light source that emits a laser beam toward a test site that is a region of a skin surface of a biological object and a control device that generates a control signal that controls the light source and causes the light source to emit the laser beam in a modulated manner. The laser beam emitted from the light source in a manner modulated in accordance with the control signal from the control device whereby the test site is irradiated is absorbed at the test site and generates a pressure wave that is a thermoelastic wave by the photoacoustic phenomenon.

A terminal mounted in advance on a battery of an instrument that is a management target wirelessly transmits a battery state obtained by detecting an electric property related to a remaining battery amount of the battery and a terminal ID for identifying the terminal, and a management device displays remaining amount information related to the battery remaining amount on a screen based on the terminal ID and the battery state received from the terminal. This allows a user to easily figure out the remaining amount of a battery being used in an existing instrument.

A locus detection unit detects a locus traced by an input unit that is attached to a body. A pattern determination unit determines an input pattern based on the locus detected by the locus detection unit. A transmission unit transmits the input pattern determined by the pattern determination unit as input information to an external device. A reception unit receives output information transmitted from the external device. A tactile output unit provides, to the body, the output information received by the reception unit as a simulated tactile sense of the skin being traced.

Input/output device

Each first terminal mounted in advance on an item transmits first vibration data and a first terminal ID by radio wave in response to vibration detection, each beacon terminal disposed in advance at a place in a room intermittently transmits a beacon signal and a beacon ID by radio wave, a management device sequentially records each first terminal ID received together with the first vibration data and the beacon ID received together with the beacon signal to a detection list in a storage unit, acquires, from the storage unit, terminal information related to the first terminal ID recorded in the detection list and position information related to the beacon ID received concurrently with the first terminal ID, and displays the terminal information and the position information on a screen.

A wavelength swept light source includes a sawtooth waveform as a main waveform and an exponential component of the sawtooth waveform to the controlled voltage of the electro-optic deflector. The controlled voltage is controlled so that, as an oscillation wavelength to be swept is swept towards a longer wavelength side, a change rate of the oscillation wavelength is increased.

Wavelength swept light source

An object of the present invention is to provide a noninvasive constituent concentration measuring apparatus and constituent concentration measuring apparatus controlling method, in which accurate measurement can be performed by superimposing two photoacoustic signals having the same frequency and reverse phases to nullify the effect from the other constituent occupying large part of the object to be measured. The constituent concentration measuring apparatus according to the invention includes light generating means for generating two light beams having different wavelengths, modulation means for electrically intensity-modulating each of the two light beams having different wavelengths using signals having the same frequency and reverse phases, light outgoing means for outputting the two intensity-modulated light beams having different wavelengths toward a test subject, and acoustic wave detection means for detecting an acoustic wave generated in the test subject by the outputted light.
