Abstract: PURPOSE: A steering column connecting device prevents the generation of crack and frictional noise by being intensified against the direction of rotation of a column shaft and the damage of a driver's head by easily being ruptured by longitudinal weight. CONSTITUTION: Many slots(34a) arranged longitudinally for being easily ruptured by longitudinal load are formed on the middle flat portion of many connecting panels(34). Thus, a column shaft is strong against rotational load with being week against longitudinal load. Thus, when a load is longitudinally applied on a column shaft, a lower shaft(32) is pushed up to a steering wheel, an upper shaft(30) is lowered down, thereby lowering the height of the steering wheel. Therefore, the collision of a driver's head and a steering wheel is prevented.

CONSTITUTION: A measuring or security system(1) for detecting the distance between an object(2) or a person(2) from a given point of reference, comprising a first transmitter/receiver device(10) enabling production of and wireless transmission of a control signal to a separate second transmitter/receiver device(30) and reception of an acknowledgement signal transmitted by the second transmitter/receiver device(30) on receiving control signal. Both transmitter/receiver devices(10,30) have a signal source(24,24,25,26) producing pulses as a control signal or an acknowledgement signal. The pulses have a monotonously decreasing or increasing frequency during pulse duration or are made of overlapping pairs of like pulses. The other transmitter/receiver (10,30) has at least one dispersion filter(11) with a given frequency dependent signal transit time on its receive side so that received pulses can be time-compressed. Transit time is adapted to the modulation on transmit side in such a way that spectral signal components of the control or acknowledgement signal coincide substantially at dispersion filter output(11) as a result of varying frequency-dependent signal transit-times through said filter and appear thus with slight temporal imprecision.
