摘要:
A brake system with traction control, having a master brake cylinder for at least one brake circuit and having a brake booster is proposed. By operation of a pump, servo pressure is fed into the brake booster via a pressure connection provided on the brake booster, and the servo pressure reaches a pressure reservoir through a bore provided on the brake booster. From there, given a corresponding open passage position of magnetic valves, the servo pressure, via a supply line, reaches the pressure cylinder present in the brake booster, and in the pressure cylinder there is a valve slide that, via a servo piston, actuates a pressure rod leading to the master brake cylinder.

A brake booster for a pressure-fluid-actuated, and in particular hydraulic, brake system equipped with both ABS and traction control has a servo piston that is controllable by a brake pedal, and an additional piston that is controllable via a magnetic valve assembly in traction control operation; to control a brake pressure in the brake system, both pistons act via a pressure rod upon the brake piston of a master brake cylinder. For the sake of a short structural length of the brake booster, the additional piston is embodied as an annular piston, which coaxially surrounds the pressure rod and is sealed off from it, and which rests on a radially protruding driver element of the pressure rod in order to displace it.

A brake system having a master brake cylinder embodied as an electrohydraulic booster, this cylinder communicates via a piston rod with a brake pedal. The piston rod acts upon at least one master cylinder piston, via which in turn a brake chamber can be put at brake pressure. As a result, brake fluid flows via brake lines to corresponding wheel brake cylinders. Also associated with the master cylinder piston is a servo piston chamber, which communicates via a control element with an apparatus for supplying power brake fluid. This control element is controlled via a controller. The controller controls the control deviation, which is derived from a set-point value forced by a piston rod travel transducer having a following control unit, and from the actual value, which originates in a travel transducer of the master cylinder piston. As a function of the rod travel the control unit following the piston rod travel transducer generates set-point value indications, which are intended to move the master cylinder piston in accordance with the driver's braking behavior. From the travel transducer signal of the piston rod transducer, via a performance graph, the feedback of the brake pressure to the piston rod is also derived and converted, so that the driver on the one hand can feed in pressure slowly and purposefully without feedback, until automatically, with increasing pressure, or in other words with a corresponding rod travel, the feedback of the brake pressure to the driver's foot begins, and on the other hand, rapid braking is effected with immediate feedback to the driver's foot.

A message may be used to update computing system of a commodity transaction. The message may include a commodity identifier, a date term, a quantity term, and a price term. The price term may include a formula arrangement or reference to a formula arrangement for calculating a fractional exposure of the entity to the commodity on each date in which an event affecting commodity transaction occurs. Each of these fractional exposures may be calculated for each commodity transaction and stored as separate entries in a data structure. The entries may then be updated, queried, and/or reorganized to generate an exposure position.

An analyzer module may read a selector key and a financial object number stored within a financial object. The financial object number may be sent to a selector module associated with the selector key. The selector module may read a selector strategy key stored within the financial object. A processor programmed by the selector module may retrieve a set of position values associated with the financial object based, at least in part, on the selector strategy key. A mapping module may be chosen by the selector module based upon a financial instrument type. The mapping module may store the position values within the financial object. A price calculator may generate a key figure for each of the position values. A list of the position values may be displayed to a user on a display device.

A method for producing an instant ground meat product from at least one ground meat molded blank which is placed on a rack or a bottom of a drying chamber of a freeze-drier in order to be freeze-dried. A projection surface of the ground meat molded blank has a maximum size, such as maximum diameter or edge length, of 2 to 16 cm on the rack or tray of a freeze-drier and a maximum height of 1 to 4 cm in relation to the rack.

Methods of making iterative low-dose computed tomography (CT) efficient and applicable to clinical practice employ selection of optimal views for CT reconstruction. By optimizing the views for CT reconstruction, the method of the present invention can generate reconstructions at a pre-specified low radiation dose and/or in near real-time. A feature-oriented framework for a task-driven, object-driven, and dose-minimizing selection of X-ray views is provided, which can utilize models of features to be mapped. The models can be derived from a patient population to minimize the dose per exam and/or from a specific patient to minimize the dose per procedure. The method of the present disclosure can be incorporated into a CT system, or can be embodied in a data storage medium as a program.

A rotary switch is disclosed which has a central handle (12) which is rotatable about a central axis (Z), a ring-shaped shield (16) surrounding the handle (12), a rotary button (18) which is arranged on the shield (16) and is rotatable about an axis (V) offset from and parallel to said central axis (Z), and a potentiometer (28) which is adjustable by means of the rotary button (18). The potentiometer (28) is radially spaced from the offset axis (V), and is coupled with the rotary button (18) by means of a gear (24, 26). The potentiometer (28) is offset radially inwards from the offset axis (V) towards the central axis (Z).

The present invention relates to an exhaust emission control apparatus for an internal combustion engine and a process for operating it. The exhaust emission control has a particulate filter for filtering particulate matter from the exhaust of the internal combustion engine, at least one temperature sensor for detecting the temperature of the exhaust, an evaluation unit for evaluating the detected temperature, particularly with regard to a particulate mass burned during a regeneration operation of the particulate filter. The temperature sensor is positioned inside the particulate filter.

A method and device for triggering a solenoid valve for injecting fuel into an internal combustion engine is described. The triggering phase of the solenoid valve is subdivided into a pull-up phase and a holding phase. During the pull-up phase, a valve needle of the solenoid valve is caused to open by a first current intensity flowing through a magnetic coil of the solenoid valve. During the holding phase, the valve needle is held in the open state by a second, lower current intensity flowing through the magnetic coil. At least once at the beginning of the pull-up phase, a booster phase is activated during which a pulse-shaped booster current from a booster capacitor charged to a high voltage flows through the magnetic coil. During the triggering phase of the solenoid valve, a plurality of booster pulses are activated in succession, whose time position within the triggering phase is freely selectable.
