Abstract: A brake unit including a brake disc of a material having a high thermal loading capacity and a brake pad that cooperates with it in tribological fashion. The brake disc is essentially made of a short-fiber reinforced ceramic material, whose thermal conductivity, in particular transversely to the disc surface, is at least 20 W/mK, preferably about 30 to 45 W/mK. The brake disc is combined with a brake pad having an organically bonded matrix. The brake pad may be a conventional series brake pad. The brake unit provides an optimal pairing of a brake disc, having a high thermal loading capacity, with a conventional brake pad in light of a reasonably expected brake pad service life, and in light of other tribological requirements, such as the friction coefficient.

A completely non-metallic brake unit and a method for its manufacture are also disclosed.

Abstract: This invention provides a method of forming a component made of an artificially and plastically formable material which can be hardened by artificial aging. The component is first shot-peen-formed in the unhardened condition and is subsequently, artificially aged. During artificial aping it is subjected to an exterior pressure load causing a creep of the impact-body-forming material to conform to a mold having the desired shape.

Abstract: The invention particularly relates to the detection of fast-flying targets by means of an HPRF radar system that operates with a plurality of switchable pulse-repetition frequencies (PRFs). In the method, a high velocity resolution is attained, which permits a reliable detection of a multiple-target situation. At the same time, a precise range determination is attained with a high range resolution by means of a pure transit-time measurement of the pulses. The length of the used range gates is selected to correspond to the anticipated target length.

Abstract: A method for driver-behavior-adaptive control of a variably adjustable motor vehicle accessory. One or more parameters indicative of driver behavior are sensed and a pertinent driver behavior is ascertained therefrom. Accessory adjustment is performed variably as a function of the driver behavior that was ascertained. The driver behavior is ascertained in terms of a long-term driving manner component, and a short-term dynamic demand component and/or a steady-speed request component. Accessory adjustment is performed, if a short-term dynamic demand exists, in accordance with an adjustment characteristic having a dynamic level corresponding at least to that dynamic demand. When a constant-speed request exists, accessory adjustment is performed in accordance with a relevant low-dynamic adjustment characteristic. Otherwise, accessory adjustment is performed in accordance with an adjustment characteristic determined by the long-term driving manner component.

The ceramic thermal insulating layer has a porous structure which is opened up by the formation of microscopic fissures formed near the surface of the layer by the shot peening.

Abstract: The invention relates to a method for monitoring the earth's surface with a moving aircraft using a radar sensor with a synthetic aperture. In order to produce high resolution radar images, the flight parameters of the aircraft are also required. According to the inventive method, key parameters, such as speed and acceleration, are detected in the sight line of the radar sensor from the radio signals received. One of the advantages of the invention is that an inertial navigation system (INS) is no longer required for this purpose.

Abstract: In a method for the probabilistic estimation of measurements, based on a measurement signal in which an interference signal is superimposed on the value to be measured, the measurement signal is sampled at specified chronological intervals. A defined measurement range associated with the value to be measured is divided into discrete values and a model is formed of a process on which the measurement signal is based with discrete states that correspond to the discrete values of the measurement range. In the model, a probability value of the occurrence of each state is assigned for each sampling time, and the value to be measured is determined on the basis of the probability value of at least one state in this model. In addition, for each state of the model at a sampling time, a probability for the state to remain in its current state is determined, as well as a probability for the state to change to another state by the next sampling time.
