Abstract:
A television receiver in which a microcomputer controls an operating part, and a clock generator for the microcomputer is synchronized by synchronization pulses in the television signal transmitted to the receiver. The clock generator is also in the form of a control generator for a switching network part and for the deflection stages of the television receiver. The signal from the clock generator is divided and processed by a pulse-width modulator. This pulse-width modulator emits a control signal for controlling the switching network part.
Abstract:
Circuitry for limiting a rectified operating voltage.To recover energy from unutilized power from the secondary winding of a switching-network transformer, it is recirculated to the primary winding through a diode. When appliances fail, the excess energy component can increase to the extent that components are destroyed because the operating voltage increases.To prevent this situation the excess energy is recirculated into a higher operating voltage U.sub.S through a diode and through another secondary winding of the transformer. The number of turns in the second secondary winding and its polarity ensure that the flyback voltage U.sub.R will be higher than the difference between U.sub.S and U.sub.B.Switching-network components in conjunction with rectifier modulators in television receivers.
Abstract:
A circuit is provided for the correction of east-west pincushion distortions on the picture screen of a television receiver. The circuit includes a diode modulator, which is controlled via a coupling coil from a control stage switched by a horizontal scanning frequency, frame frequency modulated rectangular signal as well as a diode connected to the coupling coil for returning of stored energy to an electrical energy supply source of the television receiver. An electronic switch is connected in parallel to the diode. A rectangular pulse signal is applied to the control electrode of the electronic switch. The polarity of the switching connection provided by the electronic switch is opposite to that of the diode. The electronic switch permits a current directed oppositely to the current running through the diode to pass through the coupling coil during the nonconducting phase of the control stage.

Abstract:
A device and a method for regulating at least one vehicle dynamics controlled variable (vGi) which describes a motion of a vehicle, is described. At least one vehicle dynamics variable is determined in a determination device. A regulator device with which actuators are triggered for regulating the at least one vehicle dynamics controlled variable is provided, the sensitivity of the regulator device being influenceable. Sensitivity of the regulator device in at least one operating state of the vehicle is determined by at least one of the vehicle dynamics variables thus determined.

A system for controlling the traction slip of a vehicle including identifying a start situation with a high coefficient of friction uphill or with a heavy vehicle load, and once the start situation is identified and traction slip prevails, reducing a brake control intervention and/or increasing the nominal engine torque.
Abstract:
A nitrated piston ring for the piston of an internal combustion engine. The piston ring has a circumferential indentation in its flank surface facing away from the combustion pressure. This indentation has a depth of a few Am and receives lubrication to prevent plating of aluminum from the aluminum piston on the flank surface of the piston ring.
Abstract:
Transformation of a speech signal comprises separating the speech signal into two signal parts (a, b), where (a) represents the quasistationary part and (b) the transient part of the signal. The signal (b) is filtered inversely and is supplied in parallel to a transient detector and a pitch manipulator, while the signal (a) is subjected to a spectral analysis. The transformation circuit permits well-defined manipulation of any speech signal, which is advantageous partly for hearing-impaired persons, partly for persons having normal hearing ability in noisy environments. Finally, the circuit has been found to be extremely expedient for synthesizing well-defined sounds, which is of great importance in the control of hearing aids (hearing loss simulator).
Abstract:
In a vehicular control system in which target braking torques are set for each of the driven wheels, the smaller target braking torque for the driven wheels is determined. Based on this smaller target braking torque, a target engine torque is calculated, and the engine torque is varied to conform to the target engine torque. Residual braking torques are calculated as differences from the target braking torques for each driven wheel and the target engine torque. These residual braking torques are realized by varying the brake pressure. Therefore the target braking torque is split into an engine torque which is equal for both driven wheels and into a braking torque which may be different for each driven wheel.
Abstract:
A required yaw rate value is determined based on driver inputs such as steering angle, master cylinder pressure, and throttle butterfly angle. The required yaw rate is compared to a measured actual yaw rate value and the actual yaw moment acceleration is influenced based on the comparison.
