Abstract: The present invention provides an object-position detector apparatus and detection method capable of detecting an object with high accuracy even in such a situation that adjacent objects or structures are close to each other such that reflected waves interfere with each other, as compared with the prior art. In the object-position detector apparatus that detects a position of an object based on a radar signal from a radar apparatus, a position estimator unit is configured to estimate presence or absence of and a position of the object using a machine learning model learned by predetermined training image data representing the position of the object, based on image data including the radar signal, and output image data representing the presence or absence of and the position of the estimated object.

Abstract: An embodiment of the present invention provides a sphygmomanometer that is worn on a measured part of the left wrist of a subject (user) for use. In the sphygmomanometer, on an inner peripheral surface of a band-like body that constitutes a base of a band, a portion for installing a pressure cuff and a protrusion for installing an antenna substrate are separately provided, and the pressure cuff and the antenna substrate are respectively installed on these portions.

Abstract: In an apparatus for measuring biological information using a radio wave, a technique for acquiring an index related to a setting position of the apparatus with respect to a measurement site is provided. A biological information measurement apparatus (1) according to an aspect of the present disclosure includes a transmitter (3) configured to transmit a radio wave toward a measurement.

Abstract: Provided is a technique for detecting a state of an occurrence of a body motion of a measurement target person affecting measurement by using an apparatus configured to measure biological information using a radio wave. A biological information measurement apparatus (1) according to an aspect of the present disclosure includes: a transmitter (3) configured to transmit a radio wave to a measurement site of a living body; a receiver (4) configured to receive a reflected wave of the radio wave by the measurement site and output a waveform signal of the reflected wave; a feature extractor (1051) configured to extract information indicating a feature of a waveform from the waveform signal; and a body motion detector (1052) configured to detect a state of an occurrence of a body motion of the living body affecting measurement of the biological information, based on the extracted information indicating the feature of the waveform.
