An air spring hammer device comprises a drive piston, moving axially back and forth, with a front face of hollow embodiment and a hammer piston moving in said hollow. A ventilation slot is embodied in a guide wall of the drive piston. The drive piston may be guided in a guide tube. The guide tube comprises several idle openings. A moving control element is arranged on the exterior of the guide tube, in which control openings, corresponding to the idle openings, are provided. In an idle operating mode, the control element is in an open position, via which the ventilation slot, the idle openings and the control openings can be brought into connection with the environment.

A proportional pressure adjustment valve is described which comprises one valve part with inlet and outlet openings (4) and at least one closing mechanism (7) for control of a valve (12), the same as a magnet part having one magnet core, one magnet coil and one displaceably disposed magnet armature. An actuating element (11) cooperates with the armature, actuating the spherical closing mechanism (7). The hydraulically active cross section of the valve (12) is essentially determined by the length of the valve (L), the diameter of the valve (D) and th diameter (d) of the part (13) of the actuating element (11) which penetrates into the valve. According to invention, the ratio of the length of the valve (L) to the diameter of the valve (d) is less than 2.0.
摘要:
A method is described for detecting brightness signals from a multiplicity of light-sensitive sensor elements, in particular CCD lines or arrays, in which the brightness signals are amplified in such a way that an A/D converter which digitizes the amplified brightness signals works in its permissible working range. For the brightness signal of a predetermined sensor element, the gain is reduced in steps, preferably in binary steps, from a maximum gain factor down to a working value at which the A/D converter works in the permissible working range. For each following sensor element, the working value of the respective preceding sensor element is used as the maximum gain factor. The number of changeover operations of the amplifier is considerably reduced and thus the detection time is shortened.

In a method for data transmission in which the binary original data (D0, . . . , Dm) is transferred from a transmitter to a unit of a receiver (1), selected preferably by means of a binary base address (A0, . . . , An), preferably to a register (80, . . . , 87), where the original data (D0, . . . , Dm) and preferably also the base address (A0, . . . , An) are transmitted through one or several data lines, the inverted original data (inversion data) (D0′, . . . , Dm′) and preferably also the complementary base address (complementary address) (A0′, . . . , An′, Ak) are transmitted by the transmitter. The transmitted inversion data (D0′, . . . , Dm′) and preferably the transmitted complementary address (A0′, . . . , An′, Ak) are inverted in the receiver, the transmitted base address (A0, . . . , An) and the transmitted original data (D0, . . . , Dm) are compared with the inverted complementary address (A0′, . . . , An′) and the inverted inversion data (D0′, . . . , Dm′) bit serially (0, . . . , n) and (0, . . . , m) respectively in each case, or instead of inversion and subsequent comparison an EXOR operation is performed on the base address (A0, . . . , An) and (D0, . . . , Dm) with complementary address (A0′, . . . , An′) and inversion data (D0′, . . . , Dm′). The transmitted original data (D0, . . . , Dm) is transferred to the unit selected by means of the transmitted base address (A0, . . . , An) only if all bit for bit comparisons result in agreement. This ensures error-free data transmission. The method and the circuit arrangement are used in particular for data transmission in vehicle occupant protection system s between a central unit and vehicle occupant protection devices.
摘要:
A process for evaluation of cornering of a vehicle equipped with an automatic transmission by use of electronic transmission control device having a calculation unit, a micro-controller, a memory device and a control device for start up of a hydraulic transmission control device. During a first processing operation (S1), a transverse acceleration (a_Quer) of the vehicle is determined by the calculation unit (30) from wheel speed (n_Rad) of the vehicle measured by a measuring device (34). During a second processing operation (S2), a driver-type theoretical value (FT_Soll) is determined from a vehicle transverse acceleration (a_Quer) and a vehicle speed (v_F). A gear change characteristic line (SL) is determined, based upon an increment (INKR) between the driver-type theoretical value (FT_Soll) and a driver-type actual value (FT_Ist), from several gear change characteristic lines each one associated with a certain driver type or cornering style.

The invention relates to a process to evaluate start-up for an automatic vehicle gearbox, said process having the following steps: 1) a signal associated with an engine torque (M_M) or an engine speed (n_M) is emitted from an engine control device (27), and a signal associated with a torque (M_T) or a speed (n_T) of the turbine shaft (18) is emitted at the electronic gear control unit (11) by a measuring device (24) on a turbine shaft (18) of a converter (2) of the automatic gearbox (1); 2) the electronic gearbox control unit (11) determines a maximum value (Max) from time-related differences (DIFF(t)) between the engine torque (M_M) and the torque (M_T) of the turbine shaft (18) or the difference (DIFF(t)) between the engine speed (n_M) and the speed (n_T) of the turbine shaft (18); 3) a gear-change characteristic (SL) characterising a particular start-up style by comparing a theoretical driver-type value (FT_Soll_n) associated with the maximum (Max) with an actual driver-type value (FT_Ist) and the setting of a counter (39) is determined on the basis of the maximum value (Max) of the differences (DIFF(t)), said gear-change characteristic being meant to emit control signals to the hydraulic gearbox control unit (10).
