Abstract: A method creates determination spaces for determining a road surface state of a road surface on which a vehicle is running from output waveform data obtained by measuring changes in a physical quantity of a tire of the vehicle during the running using information regarding road surfaces and the output waveform data. The method includes obtaining the output waveform data in a plurality of different road surface states and a running condition at times of measurement of the output waveform data, classifying the output waveform data into a plurality of groups on a basis of the running condition, performing, for each group, machine learning using training data where the output waveform data is associated with information regarding the road surface states, and creating the determination space corresponding to the group.

Abstract: A transducer includes a flexible substrate, a piezoelectric element formed on a surface of the flexible substrate, and a support member, in which holes are formed, having a higher rigidity than the flexible substrate. The surface of the flexible substrate has an element region in which the piezoelectric element is continuous in a planar direction of the piezoelectric element. The support member is stacked to the flexible substrate in a manner such that the holes face the element region. The flexible substrate is freely movable in each of the holes, and a region of the flexible substrate corresponding to a region other than the holes of the support member is fixed to the support member.

Abstract: A door handle includes a door handle case and an electrostatic sensor provided in the door handle case. The electrostatic sensor includes a detection electrode that is formed of a flat conductor plate, or that is formed on a surface of a flat substrate or within a flat substrate. The detection electrode includes a middle portion in a longitudinal direction of the detection electrode and includes peripheral portions proximal to both end portions of the detection electrode in the longitudinal direction. For a width of the detection electrode in a direction perpendicular to the longitudinal direction, each peripheral portion is wider than the middle portion, and the width of the detection electrode gradually increases toward each end portion in the longitudinal direction.

Abstract: A tire wear measuring device that detects wear of a tire based on a magnetic field from a magnetic object embedded in the tire includes magnetic sensors and a battery. The battery is capable of transmitting the magnetic field from the magnetic object, and has an outer edge from which the magnetic field from the magnetic object is emitted as an emission magnetic field. Each of the magnetic sensors is disposed in a position where the emission magnetic field is detectable by the sensor.

Abstract: A tire deterioration inferring (estimating) method uses a tire deterioration inferring device placed on the inner surface of a tire. The method has: a deformation velocity measurement step of measuring a tire deformation velocity, which is the deformation velocity of the tire while the tire is rotating, and obtaining time-series changes in the tire deformation velocity; a calculation step of calculating peak values of the tire deformation velocity from the time-series changes in the tire deformation velocity; and an inference step of inferring the degree of the deterioration of the tire by using a first peak value, which is a peak value of the tire deformation velocity before and at the stepping of the tire or at and after the kicking of the tire, the first peak value being in the time-series changes in the tire deformation velocity.
