摘要:
A method for controlling and/or regulating an electronically triggerable vehicle brake system, operating on the return principle, and to such a brake system in which by an adapted triggering of the drive motor for the pressure generator, the pumping quantity of the pressure generator is varied such that the difference between these flows of pressure medium to and from the master cylinder assumes a minimal value, preferably a value of zero. To that end, the driving rpm of the pressure generator is preferably varied. The trigger signal for the drive motor can be ascertained by an electronic control unit from measurement outcomes from sensors within the vehicle brake system, or it can be estimated with the aid of a hydraulic volume model stored in memory in the control unit. The trigger signal can be controlled or regulated.

A method and apparatus for coupling an ATM communication layer to a plurality of N mutually time-independent time-division multiplex communication terminals having an overall payload cell rate CRN which involves: generating a control signal sequence with a clock rate corresponding to the overall payload cell rate CRN of the N time-division multiplex communication terminals, whereby the control signals can represent a first or a second status; offering a fixed data pattern; transmitting the ATM cells coming from the ATM communication layer into an ATM cell waiting list; transmitting, on demand, an ATM cell from the ATM waiting list to the requesting time-division multiplex communication terminal when the respectively oldest control signal of the control signal sequence represents the first status, and transmitting the fixed data pattern to the requesting time-division multiplex communication terminal when the oldest control signal of the control signal sequence represents the second status; and deleting the oldest control signal of the control signal sequence. The method enables a frictionless coupling of an ATM communication layer having a plurality of mutually independent time-division multiplex communication terminals, whereby variable data rates (burst behavior) of the ATM layer as well as of the time-division multiplex communication terminals can be decoupled from one another and good cell delay variation (CDV) properties can be assured.

摘要:
A system for changing the damping characteristics of shock absorbers, based on the signals (Xar'(t)) of the relative movements such as the spring deflection velocity, between the vehicle superstructure and wheels, additional signals (Xar"(t)), such as the spring deflection acceleration, are determined. The two signals are logical linked so that the control of a vehicle variable, such as the activation of adjustably designed shock absorbers, is carried out. This makes it possible to change the characteristic of the shock absorber in operating phases of low damping forces of the shock absorber. This feature optionally reduces noise at damping characteristic changes.

摘要:
The invention relates to a method and to an apparatus for optimizing transmission security and failure security in high-bit-rate data networks by via signal line redundancy between the network nodes, such that parallel signal lines can optionally be occupied, or can be switched, as working lines or protection lines, and selectors, bridge circuits, and interface modules are provided at the network node side. According to the invention, each of the parallel signal lines is connected at the network node side with a respective interface module, and all interface modules are in principle in the active state. Given failure of one of the interface modules, this failure is immediately countered by a signal line changeover, and line errors are immediately countered by the provided interface module redundancy. Furthermore, error messages can be transmitted, via a corresponding link, between the interface modules of the incoming and outgoing parallel signal lines in each of the network nodes.

A rotary particle dryer has a shaft extending along an axis and a hollow drum coaxially and spacedly surrounding the shaft and rotatable about the axis in a direction. A set of axially extending inner baffles fixed to the shaft extend radially outward therefrom and each form at least one angularly open inner pocket. A set of axially extending outer baffles fixed to the drum extend radially inward therefrom and each form at least two angularly open outer pockets. Structure mechanically connects the inner baffles directly with the outer baffles.
