Abstract: An electromagnetic shield is disposed in front of a radar. The radar has different angles of view in different directions. The radar has a first angle of view in a first direction and a second angle of view in a second direction. The second angle of view is smaller than the first angle of view. The second direction is orthogonal to the first direction. The electromagnetic shield has a pair of first sides and a pair of second sides. The pair of first sides face each other in the first direction. The pair of second sides face each other in the second direction. The electromagnetic shield includes a dielectric. At least one of the pair of first sides includes a structure having at least one selected from the group consisting of a projecting portion and a recessed portion.

Abstract: A method for producing a wiring circuit board includes a preparation step of preparing a substrate; a first patterning step of forming a first insulating layer on one side of the substrate in a thickness direction; a second patterning step of forming a conductive pattern on one side of the first insulating layer in the thickness direction; and a deposition step of depositing a metal on the other side of the substrate in the thickness direction and forming a first metal support layer. The conductive pattern has two terminals, and two wirings. The first metal support layer has a terminal support portion supporting the terminals, a wiring support portion supporting one of the wirings, and a second wiring support portion supporting the other wiring and disposed spaced from the wiring support portion.

Abstract: A film contains a β-1,3-glucan derivative obtained by introducing an acyl group into a β-1,3-glucan and at least one resin selected from the group consisting of a rosin-based resin, a terpene-based resin, and a petroleum-based resin. The acyl group is represented by RCO—, and the R is a hydrocarbon group having 1 or more and 5 or less carbon atoms. Parts by weight of the resin with respect to 100 parts by weight of the β-1,3-glucan derivative are 90 parts by weight or less. A pressure-sensitive adhesive tape includes the film and a pressure-sensitive adhesive layer.

Abstract: A method of sleep stage detection using vital sign features derived from PPG signals. The method includes performing a logistic regression operation based on a machine learning classifier model to calculate an indication value for an intermediate epoch. The indication value is calculated based on the vital sign features for the intermediate epoch as well as those of the preceding and succeeding epochs. The method then detects the sleep stage of the corresponding intermediate epoch based on the indication value for the corresponding intermediate epoch.
