Abstract: For an easy calibration using calibration particles, provided is a measuring device to capture images of target objects. An image analyzer acquires multiple images obtained at a predetermined time interval, (a) specifies the mean-square displacement of a bright point of a calibration particle based on the displacement of the bright point of the calibration particle in the multiple images in a calibration mode, and (b) specifies the mean-square displacement of a bright point of the target particle based on the displacement of the bright point of the target particle in the multiple images in a measurement mode. A particle size analyzer (c) derives the particle size of the target particle from the mean-square displacement of the bright point of the target particle based on the mean-square displacement of the bright point of the calibration particle and the particle size of the calibration particle in an analysis mode.

Abstract: Provided is a particle measurement device in which irradiation light emitted by a light source is expanded by an expander in a shape satisfying the requirements of a diffractive optical element, converted into parallel light, and made to enter the diffractive optical element. The diffractive optical element shapes the irradiation light entering therein into a flat top beam in which the cross section in the focal position thereof has an elongate rectangle shape. The intensity distribution of light can be made substantially uniform in a detection area formed by the shaped irradiation light.

Abstract: An installation structure of a vibrator includes elastic members formed of an elastic material, the elastic members being arranged between a housing of a listening device, and the vibrator accommodating an electromechanical transducer for transducing an electric signal into mechanical vibration. The vibrator is installed on the listening device such that a lower surface of the vibrator is disposed at a position facing an ear cartilage in a state where the listening device is worn on an ear, and a first mechanical impedance of the elastic members between the vibrator and the housing is set smaller, at a frequency of 200 Hz to 1000 Hz, than twice a second mechanical impedance, with which the vibrator is loaded, of the ear cartilage.

Abstract: A system identification device for performing fast real-time identification for a system from input/output data includes a filter robust to disturbance, by setting the maximum energy gain from the disturbance to a filter error, as an evaluation criterion, smaller than a given upper limit. The filter estimates a state estimation value of a state of the system.

Abstract: The biological particle counter has a first circuit configured to generate a first signal corresponding to fluorescence from the biological particle in response to irradiated light. A measurement value obtainer is configured to obtain, from the biological particle counter, a voltage value of the first signal for a calibration particle obtained in such a manner that a fluorescence agent infiltrates into a surface of a polystyrene particle. A circuit adjuster is configured to use reference data indicating a correspondence relation between a fluorescence agent parameter value correlated to the content of the fluorescence agent and a reference voltage value of the first signal corresponding to the fluorescence agent parameter value, thereby specifying the reference voltage value of the first signal corresponding to the fluorescence agent parameter value for the calibration particle. The first circuit is adjusted such that the voltage value of the first signal for the calibration particle reaches the reference voltage value.

Abstract: If input signal is transmitted to a main body unit, a sensor amplifier stores the input signal in itself as measurement data, and transmits the input signal with the added transfer order information to the main body unit. By checking the transfer order information added to the input signal, the main body unit can confirm if the input signal is deficient or not. Upon the end of the measurement of the physical quantity, the main body unit transmits the retransmission request that requests the retransmission of the deficient portion of the data to the sensor amplifier. According to the retransmission request from the main body unit, the sensor amplifier extracts the deficient portion of the input signal data stored in itself and retransmits the extracted input signal data to the main body unit.
