| 20080238188 | Method of Modulating Brake Pressures on Motorcycles - Disclosed is a method and brake system for modulating brake pressures in a motorcycle brake system with anti-lock function and integral braking function. Inlet and outlet valves ( | 10-02-2008 |
| 20100168978 | Vacuum Brake Booster and Method for the Operation Thereof - A vacuum brake booster and a method of operation of a vacuum brake booster of a vehicle brake system is disclosed. The vacuum brake booster includes a housing subdivided into at least one vacuum chamber and at least one working chamber. The vacuum chamber is connected to a vacuum source by way of a vacuum port. A sensor unit is associated with the vacuum chamber and is configured for sensing a pressure in the vacuum chamber and supplying a sensed pressure value to an electronic control unit (ECU). The ECU includes an evaluating unit for evaluating the sensed pressure value and calculating the operating point of the vacuum brake booster solely on the basis of the sensed pressure in the vacuum chamber. Plausibilisation of the sensed pressure value is performed to monitor the overall system and identify defects of the sensor unit or the vacuum brake booster. | 07-01-2010 |
| 20100332038 | METHOD FOR CONDITIONING A CONTROL VALVE - A control valve conditioning method in an electrohydraulic pressure control unit comprising at least one electrically triggered solenoid valve that is controlled in an analog manner. The solenoid valve is operated at a specific operating current according to a functional correlation or characteristic diagram between the valve current and the differential pressure characteristic curve when the pressure is controlled, said functional correlation or characteristic diagram being stored in the pressure control unit. The method comprises the following steps: a) temporarily applying at least one anti-hysteresis pulse to the solenoid valve during which a current is set far below or far above the operating current in the valve; b) applying the anti-hysteresis pulse at the desired operating current before or during controlled operation, and c) applying the anti-hysteresis pulse wherein the duration is limited in such a way that the anti-hysteresis pulse has largely no influence on the brake pressure. | 12-30-2010 |

| 20100087772 | BLOOD PROCESSING DEVICE AND METHOD FOR PURGING A SET OF BLOOD LINES ON A BLOOD PROCESSING DEVICE - The invention relates to a method for the emptying of a blood tubing set of a blood treatment device comprising an extracorporeal blood circuit including a membrane filter having a first chamber and a second chamber separated therefrom by a membrane, said first chamber being flowed through by blood in operation of the blood treatment device and said second chamber being flowed through by filtrate in operation of the blood treatment device, and said blood tubing set including an arterial blood tube and a venous blood tube which are both in communication with the first chamber of the membrane filter and which conduct blood from the patient to the membrane filter and from the membrane filter to the patient in operation of the blood treatment device, and comprising a substituate line which opens into the arterial blood tube and/or into the venous blood tube, and comprising a substituate pump which is in communication with the substituate line such that it conveys substituate from a substituate source through the substituate line, wherein, for the purpose of emptying the blood tubing set, the arterial blood tube and the venous blood tube are connected to one another such that a circuit including the membrane filter, the arterial blood tube and the venous blood tube arises, that the substituate line is disconnected from the substituate source and that air or gas is pumped into the blood tubing set by means of the substituate pump so that an excess pressure arises in the blood tubing set by which liquid is displaced into the second chamber of the membrane filter via the membrane of the membrane filter. The invention furthermore relates to a blood treatment device. | 04-08-2010 |
