Abstract: A sensor includes: a complex transfer function calculator calculating complex transfer functions; a living body component extractor extracting living body information; a correlation matrix calculator calculating a target correlation matrix from the living body information; a noise information storage recording a noise correlation matrix; a first headcount information calculator calculating first headcount information that is a tentative number of persons present in the predetermined space, based on the target correlation matrix and a threshold calculated from the noise correlation matrix; a MUSIC spectrum calculator estimating position candidates for the living bodies, using the target correlation matrix, and outputting likelihood spectra indicating likelihoods of the respective living bodies being present in corresponding positions; and a second headcount information calculator estimating second headcount information that is a more accurate number of living bodies or positions from position information that is based on the likelihood spectra and can include the position candidates.

Abstract: A mover control method includes decision processing and control processing. The decision processing is the processing of determining whether or not a mover that is carrying an object thereon is going to deviate from a traveling route, through which the mover, as well as the object, is allowed to pass. The control processing (first control processing) is the processing of controlling the mover based on a result of the decision processing.
