Abstract: A system with a transmitter for transmitting digital data via an interface to a receiver. The interface has at least one data line and a clock line. A clock generator supplies a clock signal to the clock line. The receiver uses the clock signal received from the clock line for deriving timing information for processing received digital data. The clock signal may have an amplitude that is lower than the power supply voltage VDD, typically less than half of the power supply voltage, and less stringent requirements can be applied to the waveform of the clock signal than traditionally applied to data and clock signals. The clock signals are hereby less power consuming and cause significantly less electromagnetic interference.

Abstract: A method for increasing the manufacturing certainty of soldered connections between a ceramic carrier and a printed-circuit board. It includes the method step of applying a first decomposition-resistant metallization layer on a ceramic carrier and the subsequent imprinting onto the first metallizing layer of a second metallizing layer, improving the wetting performance. In this manner, it is possible to achieve an increase in the overall metallizing layer thickness in the edge area of a soldered connection, whose solder rise in turn makes possible an optical, fully-automatic monitoring of the soldered connection.

Abstract: In a method for producing a pressure sensor, a ceramic plate is joined to a shaped ceramic part. The shaped ceramic part has a depression. Around the depression there is provided a thick-layer paste which does not completely surround the depression. As a result, the air can escape from the depression during firing and a subatmospheric pressure can thus be enclosed in the depression.

Abstract: An ABS which evaluates slip values prescribes pressure values for the wheel brakes. In order to improve the driving stability, these pressure values are varied by a brake controller using the deviation of the yawing speed from a set value and the front-axle steering angle as input variables. The brake controller determines its output values (variation values) with the aid of the fuzzy logic. Additionally, rear-axle steering is integrated into the system, the system partially also using fuzzy logic. Subsequently, an adaptation which is based on fuzzy logic and uses the brake controller and the rear-axle steering controller in a weighted fashion is proposed.

A contact is coated with a liquefied, electrically conductive, flux-free solder, and the coated contact is arranged over the other contact. Then, in the molten state, the electrically conductive solder is electroconductively connected to the other contact and hardened. In addition, a liquefied, hardenable, non-conducting bonding means is introduced between the two electronic circuits.

Abstract: Described is an ABS for vehicles in which all wheels are driven. Of particular concern is the forming of a final reference speed for the slip control. From the speeds of wheels with different speeds, an auxiliary reference speed, and a reference speed and a final reference speed for the slip control is formed . In the event of instability, however, the increase of the auxiliary reference speed determines the reference speed.
