摘要： A microbial particle measuring apparatus includes: a light emitter configured to irradiate a fluid with light of a predetermined wavelength over a predetermined measurement time; a fluorescence receiver configured to selectively receive fluorescence emitted from particles contained in the fluid and output a signal having a magnitude corresponding to intensity of the fluorescence; a signal acquisition unit configured to obtain the signal output from the fluorescence receiver at regular intervals over the measurement time; and a determiner configured to calculate a slope of waveform of the signal obtained by the signal acquisition unit, and determine a concentration of microbial particles contained in the fluid using an attenuation amount of fluorescence intensity generated in a time period in which the slope in the measurement time is smaller than a predetermined value as an amount of attenuation derived from the microbial particles.

摘要： A flow cell includes a body and a flow channel. The body is formed out of blocks made of an uniaxial crystal material and joined to one another. The flow channel is formed inside the body, so that the flow cell is configured to be used to measure particles passing through the flow channel based on reception of scattered light generated from the particles. A crystallographic c-axis in a predetermined part of the body is configured to being substantially perpendicular to both a receiving direction and a polarization direction of the scattered light.

摘要： A particle counter includes a detector that receives, using a light receiving element, interference light between scattered light and reference light, generates a detection signal corresponding to the interference light, and amplifies the detection signal using an amplifier; a counting unit that performs counting of the particle, based on the detection signal in a measurement period for measuring particle; and an optical path length variable unit that causes the optical path length of at least one of a first optical path and a second optical path to be changed at a predetermined rate, wherein the predetermined rate is set based on a flow velocity of the fluid so as to slow a change in a phase difference between the scattered light and the reference light and to make the frequency of the detection signal lower by changing the optical path length.

摘要： Provided is a hearing aid including a receiver, a microphone, an adaptive filter estimating a feedback transfer function from the receiver to the microphone, a subtractor, a hearing aid processor, a first whitening filter, a second whitening filter having a whitening filter coefficient identical to that of the first whitening filter, a coefficient updater, and a controller controlling the adaptive filter and the first and second whitening filters. The controller updates and saves, as a stabilization coefficient, the coefficient of the adaptive filter in a condition in which the autocorrelation of the first signal is low, determines the presence or absence of a change in the feedback transfer function based on the coefficient of the adaptive filter and the stabilization coefficient, and performs, when it is determined that the feedback transfer function has changed, the control in order that effectiveness of whitening by the first and second whitening filters is reduced as compared to that when it is determined that the feedback transfer function does not change.
