Abstract: The invention relates to a motor vehicle seat comprising a seat frame (G); a backrest (R), which is pivotably mounted on the seat frame (G) and which may be folded from the working position thereof in the direction of a seating surface on the seat frame (G); a longitudinal guide (101, 102), with which the seat frame (G) may be moved to adjust the seat longitudinal position in the seat longitudinal direction (L), a fixing device (120) for fixing the seat frame (G) in a pre-determined seat longitudinal position; an operating element (120b) for releasing the fixing device (120), such that the seat frame (G) may be moved in the seat longitudinal direction (L); a coupling mechanism, acting on the operating element (120b) and releasing the fixing device (120), when the backrest (R) is folded on the seat surface; a memory device (104, 105, 107), by means of which, during a movement in the seat longitudinal direction, the seat frame (G) can be automatically retained in a pre-determined seat longitudinal position, def

Abstract: In an embankment block with essentially a frame-like design for the construction of embankment structures on which plants can be planted, the front longitudinal wall (1) is shaped approximately like a shield, whereby the same projects on the top side and in longitudinal direction over the frame outlines by approximately a wall thickness.

Abstract: In a signal transmission system for broadband signals wherein the transmitting transducer and/or the receiving transducer has a non-isotropic radiation characteristic, properties of the received broadband signal, for example waveform shape, spectrum, duration and probability density function, depend on the alignment orientation of the transducers. A discriminator circuit is provided in the receiver for identifying or estimating parameters related to one or more of such properties as a measure of alignment orientation of the transducers. The invention can be utilized, for example, in noise-suppressing radio frequency message transmission systems wherein band spreading modulation (spread-spectrum-system) results in transmission of a much greater bandwidth than a conventional transmission of the message baseband frequencies.
