    Abstract: A signal processing method according to the present disclosure is for use in a signal processing system including a first magnetic detection unit, a second magnetic detection unit, and a processing unit. The signal processing method includes an angle calculating step and a failure diagnosis step. The angle calculating step includes transforming, by using an inverse trigonometric function, a sine signal, a cosine signal, and a tangent signal into a first angle signal, a second angle signal, and a third angle signal, respectively. The failure diagnosis step includes making a failure diagnosis of the first magnetic detection unit and the second magnetic detection unit by comparing with each other two or more pieces of angle information selected from first angle information, second angle information, and third angle information.

    Abstract: An imaging device incudes a pixel array including pixels arranged in columns and rows, one of the columns including a first pixel in a first row and a second pixel in a second row; a first signal line, to which the first pixel is coupled, and a second signal line, to which the second pixel is coupled, extending in a column direction of the pixels; and a first shield line, to which the first pixel is coupled, extending in the column direction. The first signal line, the first shield line, and the second signal line are arranged along a row direction of the pixels in that order.

    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.
