A method for the non-destructive testing of the volume of a test object, during the course of which a volume raw image of the test object is recorded by a suitable non-destructive imaging testing method. Then, those regions of the volume raw image are identified that are not to be attributed to the test object material. It is checked whether an identified region is completely embedded in regions that are to be associated with the test object material. If necessary, such a region is assimilated to those regions that are to be associated with the test object material, forming a filled volume raw image. Finally, a difference is generated between the volume raw image and the filled volume raw image, forming a first flaw image.

A devise that will increase an inductive proximity sensor's detection distance and detection position. The devise uses a housing in combination with a sensor and axially magnetized magnet and a target magnet to achieve the increased detection distance and position. The devise can be defined as universal because it allows different manufacturers and sizes of sensors to be used and calibrated. A treaded end section of the devise allows connection of standard conduit fittings.

The present disclosure is generally directed towards calculating a remaining length of a cable on a cable reel. Generally, a first distance between a top edge of a first flange of the cable reel and a top portion of the cable remaining on the cable reel is received at a processor. A winding characterization indicating a configuration of the cable wound on the cable reel is also received at the processor. Dimensions of the cable reel are also received at the processor and include: a diameter of the first flange, a cable reel traverse distance, and a diameter of a drum of the cable reel. The cable reel traverse distance indicates a distance between the first and second flanges of the cable reel. The remaining length of the cable on the cable reel is calculated based on the first distance, the winding characterization, and the dimensions of the cable reel.

A reset device for a gearshift lever for a gear step of a transmission in a motor vehicle comprises an electric drive device for controlling an operating element, in order to move the gearshift lever into a predetermined position, a position sensor for determining a position of the operating element, and an electric activation device for activating the drive device, depending on the position of the operating element.

The present invention generally relates to proximity sensor monitors and proximity monitor systems incorporating proximity sensor monitors. A proximity sensor monitor measures the impedance or other electrical characteristics of a proximity sensor component to determine the presence of a target. The proximity sensor monitor performs this measurement independently of a separate proximity sensor. The proximity sensor monitor is configured to compensate for differences between the measurement frequency of the proximity sensor monitor and the driving frequency of the proximity sensor.

A self-capacitance-system electrostatic-capacitance detection sensor includes: a first electrode and a second electrode, one of the first and second electrodes being set as a sense electrode, and the other of the first and second electrodes being set as a drive electrode; a sense-signal generating unit that generates a sense signal to be applied to the sense electrode; a detecting unit that detects, as a detection value, an amount of charge movement corresponding to an electrostatic capacitance of the sense electrode; and a determining unit that determines whether or not a detection target is in close proximity to both the first and second electrodes, based on a subtraction difference between detection values detected by the detecting unit when a first drive signal is applied to the drive electrode and when a second drive signal having the same frequency and a different phase is applied to the drive electrode.
