20090202732 | Method for Producing Ceramic Layers - The invention relates to a method for producing ceramic layers by spraying. A cold gas spraying method is used to produce polymer ceramics from pre-ceramic polymers. According to said method, a cold gas stream, to which particles of the pre-ceramic polymers are added via a conduit, is generated by a spray gun.

This permits the heat-sensitive pre-ceramic polymers to be spray-applied as a coating on a substrate using a cold gas spraying method. Polymer ceramics can thus be used in an economic method for the rapid production of layers with a relatively large thickness.

20130297179 | METHOD FOR MONITORING THE SIGNAL VALUE OF A VACUUM SENSOR - A method for monitoring the signal value of a vacuum sensor of a vacuum system in a vehicle, wherein a vacuum generator and a brake booster are provided in the vacuum system, an upper error threshold (−p_vac_errorthreshold) is calculated as a function of the operating states of the vacuum generator and of the brake booster, and wherein an error is identified when the signal value of the vacuum sensor exceeds the current value of the error threshold. | 11-07-2013 |
20140110994 | METHOD FOR OPERATING A BRAKING SYSTEM - The invention relates to a method for operating a braking system, including a brake booster, which is divided into at least one vacuum chamber and at least one working chamber by at least one movable partition, wherein at least one vacuum chamber is connected, or can be connected, to a vacuum source for creating a vacuum, and further including at least one sensor, which detects at least one variable such as travel and/or angle and/or force of a brake pedal actuation and/or a brake pressure that is built up in at least one main brake cylinder connected to the brake booster in accordance with a brake pedal actuation. According to the invention, the remaining vacuum in at least one vacuum chamber is estimated on the basis of at least one of the detected variables by considering actuations already performed. The invention further relates to a braking system and to the use thereof. | 04-24-2014 |
20150298670 | METHOD FOR OPERATING A BRAKE SYSTEM, AND BRAKE SYSTEM IN WHICH THE METHOD IS CARRIED OUT - A method for operating a brake system, which brake system includes a master brake cylinder, which is actuated by the driver with the aid of a brake force booster, a driver-independent pressure source, and at least one wheel brake to which a wheel speed sensor is assigned. During a braking operation initiated by the driver, which is identified in particular by a brake lamp switch, the present vehicle deceleration is determined and compared with a predefined threshold value, and the at least one driver-independent pressure source is activated if the determined vehicle deceleration reaches or falls below the predefined threshold value. A brake system for a motor vehicle, which brake system has a control unit in which the method is carried out is also disclosed. | 10-22-2015 |
