    摘要： The invention relates to a method for determining an amplitude A of a pump-induced fluid pressure fluctuation of a fluid which is regulated to a desired fluid pressure psoll by means of a pump. In this case, the method comprises providing (S1) a pressure signal of the fluid, determining (S2) the amplitude A of the fluid pressure fluctuation on the basis of the pressure signal which has been provided, checking (S3) whether the pressure signal which has been provided satisfies a predetermined plausibility criterion, and outputting or rejecting (S4) the determined amplitude A on the basis of whether the pressure signal which has been provided satisfies the predetermined plausibility criterion. This advantageously provides a combined method in which, in addition to fundamentally determining the amplitude A of a fluid pressure fluctuation, a plausibility check is also carried out immediately in order to determine whether this fluid pressure fluctuation also actually corresponds to a representative value for the current system state. Furthermore, the invention also relates to a device which is designed to carry out the above-mentioned method and to a motor vehicle having a corresponding device.

    摘要： A sensor connector compatible with various sensor unit repertoires and capable of improving production efficiency is provided. The sensor connector includes terminal modules to be inserted into a module inserted portion, and commonized pogo pin type terminal module is brought into contact with a connection terminal via slide contact segments capable of sliding relative to the connection terminal exposed to a region closer to the module inserted portion. Thus, the sensor connector can be compatible with the sensor unit 1 having various repertoires by changing, for example, the arrangement and the number of poles of the module inserted portions of the connector housing.

    摘要： A pressure sensor including a housing extending along an axial line, a diaphragm fixed to a front-end side of the housing, a piezoelectric unit disposed in a hole in the housing and including a piezoelectric element, a transmission member that transmits deformation of the diaphragm to the piezoelectric unit, and a guide member having a through hole extending along the axial line and surrounding the piezoelectric unit in the through hole. (SL/AL)≤0.26 is satisfied in the cross section perpendicular to the axial line passing through the piezoelectric element, where SL is the maximum value of the distance in the radial direction between the center of the through hole and the center of the piezoelectric element and AL is the maximum value of the distance in the radial direction between the outside surface of the piezoelectric element and the center of the through hole.

    摘要： Disclosed herein are an integrated monitoring CCTV, an abnormality detection apparatus, and a method for operating the apparatus. The abnormality detection apparatus includes a monitoring information collection unit for collecting monitoring information that includes location information, sound information and time information of a monitoring area from at least one integrated monitoring CCTV including multiple microphones; and an abnormal sound determination unit for determining whether an abnormality has occurred in the monitoring area, based on the sound information of the monitoring area, wherein the abnormality detection apparatus further comprises an explosion occurrence determination unit for, based on information about installation locations and installation directions of multiple integrated monitoring CCTVs transmitted from the multiple integrated monitoring CCTVs, generating a sensor matrix map for the multiple integrated monitoring CCTVs and calculating a location of occurrence of an abnormal sound based on the sensor matrix map when the abnormal sound occurs.
