Patent DE-19643169-A1 (DE)
Title: Stability control for vehicle
Inventor: MONZAKI SHIROU
IPC: B60T8/1755
Filed: 1996-10-18
Abstract: The vehicle is fitted with sensors to determine the amount of drift during cornering and the control selectively brakes the rear wheels to counteract the drift, by retarding the vehicle in a controlled manner. The ratio of braking force for the inside and outside rear wheels during cornering correction, varies to reduce the inside wheel braking as the drift factor is reduced. This prevents over slip correction. The control also operates the front wheel brakes selectively to control the overall stability of the vehicle. The reduction in the braking control for the inside rear wheel starts at the maximum value of drift and progressively reduces with drift. The drift is determined as the difference between the drift due to steering and road speed and that due to instability.

Patent DE-19722996-A1 (DE)
Inventor: LUEBCKE BERND
IPC: B41C1/045
Filed: 1997-06-02
Abstract: The invention relates to a method and a circuit for processing signals in an electronic graving machine, in which a series of cups arranged in a gravure screen is engraved in a printing cylinder by a burin of a graving element guided by an engraving control signal (G). In a digital signal processor (13), a transfer function is determined from function value data used to calculate a periodic screen signal for producing the gravure screen; from adjustment data for adjusting the depth of cut; from digital adjustment parameters for calibrating "light" (white) and "dark" (black); and from control data (SD). The transmission coefficients of the transmission function and/or the transmission function can be modified by the control data (SD). The engraving data (GD), which represent the different tone values between "black" and "white" which are to be engraved, are then converted into engraving control data (GSD) in the digital signal processor (13) after the transmission function. The engraving control data (GSD) undergo digital-analog conversion and the analog engraving control signal (G) is amplified in a current amplifier (16) and fed to the graving element.
