Abstract: An ultra-wideband sensor transmits impulse radio signals over a predetermined time period, detects echo signals of the impulse radio signals by way of at least one sensor of the ultra-wideband sensor and generates a time-variant channel impulse response that describes the echo signals received by the at least one sensor as a function of a time at which the respective impulse radio signal of the predetermined time period was transmitted and a path delay, uses a predetermined selection method to ascertain at least one ascertained path delay, generates a signal characteristic of the time-variant channel impulse response for the at least one ascertained path delay, uses a predetermined comparison method to determine a similarity of the signal characteristic to a reference characteristic, and detects a predetermined movement pattern associated with the reference characteristic if the similarity meets a predetermined similarity criterion.

Abstract: A method for manufacturing an insulating bar made from a thermoplastic plastics material whereof the base body has a corrugated structure comprises shaping the insulating bar as a blank having a substantially planar structure of the base body without raised portions and recesses but with the connection strips, cooling the blank to a temperature corresponding to the maximum long-term service temperature of the plastics material or lower, heating the base body to a forming temperature which, for crystalline plastics materials, is approximately 30° C. below the crystallite melting point of the plastics material or higher, and for amorphous plastics materials, is approximately 30° C. above the softening point or higher, forming the base body by a tool to produce the alternating raised portions and recesses, while retaining the geometry of the connection strips, and cooling the insulating bar to a temperature corresponding to the maximum long-term service temperature or lower.

Abstract: The coaxial plug-and-socket connector is for high frequencies, particularly in the GHz range, and comprises a socket part and a plug part as well as an elastic electrical contact element. The contact element connects the outer conductor of the socket part to the outer conductor of the plug part and is placed between the plug part and the socket part. The contact element comprises a number of elastic parts that, while under radial elastic stress, form a contact point to the outer conductor of the socket part and a contact point to the outer conductor of the plug part. Said contact points preferably lie in a plane running perpendicular to the longitudinal axis of the plug-and-socket connector and near a face of the plug part. The connector is stable up to approximately 65 GHz.

Abstract: A fastening system comprises a screw including a thread formed on a shank and configured to form a threaded bore in a plug made of a plastic material, and at least one notch formed in the shank between at least two adjacent turns of the thread. The system also comprises a clip including first and second clip bows connected at joined portions thereof. The first and second clip bows further have firs and second through apertures in their central portions which are aligned and sized to define a channel for allowing the shank of the screw to pass through. At least one of the first and second through apertures has an internal thread matching with the thread of the screw. The clip has at least one resilient lug adapted to engage with the at least one notch when the screw is fastened into the internal thread.

The adjusting device has outside and inside conductors 6, 7. The outside conductor has two housing parts 14, 15 which can be phaselessly moved toward and away from each other between two terminal positions by turning a clamping sleeve 9. The inside conductor is provided with two telescoping connecting parts 16, 18 that can also be moved toward and away from each other; each is connected with an associated housing part. The inside diameters (D) of the two housing parts and the outside diameters (d) of the two connecting parts are so dimensioned that the adjusting device has a constant impedance over its entire length.
