Abstract: In a device for the active control of motor vehicle suspensions it is proposed to incorporate a rapid levelling of the suspension system in conjunction with associated active or semi-active dampers and additional passive suspension and shock absorption elements. In this way a particularly effective separation of wheel movements and vehicle body movements is achieved together with good shock-absorbing effects on the wheel movements and levelling which maintains an adjustable vehicle height. <IMAGE>

Inventor: HENZE CHRISTOPHER P
IPC: H02M7/217
Filed: 1987-07-14
Abstract: An A.C. to D.C. power conditioner, which draws sinusoidal input current utilizes digital proportional-­integral control to provide output voltage regulation by adjusting the gain of a current program loop. The current program loop controls the state of a power switch to force the instantaneous average current in an inductor to follow the instantaneous rectified line voltage. Variable hysteresis control provides noise immunity by increasing the ripple current in an iron-cored filter inductor when the instantaneous input voltage is high. Digital proportional-integral (PI) control provides output voltage regulation by adjusting, in discrete steps, the gain of the current program loop. A multiplying digital-to-analog converter serves as an interface between the voltage regulation loop and the current program loop. The sampling rate of the PI controller is determined by the input line frequency, which allows good transient response to be obtained. The current program loop forces the current drawn by the power conditioner to follow the input A.C. line voltage, thereby electronically emulating a resistor.

Abstract: 2,6-Diacetoxynaphthalene (DAN) is produced by subjecting 6-acetoxy-2-acetonaphthone (AAN) to a Baeyer-Villiger oxidation using a peroxy compound, e.g., peracetic acid, as oxidant under conditions such that the reaction mass contains no more than about 0.1 wt.% of a mineral acid based on the weight of the initially added pure peroxy compound. The AAN is preferably produced by subjecting 2-naphthyl acetate to a Fries rearrangement or 2-naphthol to a Friedel-Crafts acetylation, to produce 6-hydroxy-2-acetonaphthone (HAN), e.g., using hydrogen fluoride as catalyst, and acetylating the HAN, e.g., with acetic anhydride.

Abstract: Area correlation of images or regions of images may be used directly to measure field distortion such as rotation, expansion, or shear, once translation disparities are removed between a pair of images. A method is disclosed for allowing relative field distor­tions to be applied between a pair of image regions as they are correlated. In binocular stereo, the method enables measurement of elevation gradients and surface curvatures. In motion analysis, the method enables the direct measurement of flow field parameters, while in template matching, rotation and magnification may be measured without the necessity of multiple templates for the same object.

Abstract: A regulation method for a multi-variable control with a PI character subjects the I component to a comparison with a lower and an upper limiting value for the manipulated variable by a maximum value selection and a minimum value selection. It is thereby guaranteed that the actuating signal, as the sum of the P branch and of the I branch, remains within these limiting values under all operating conditions and a downstream mechanical control element, for example a fuel injection pump, is thus only actuated within the mechanically and physically determined limits specified for it.
