Abstract: A predetermined number of bond cycles is carried out in order to find optimum bond parameters for a wire bonder. The bond parameters to be optimized are each varied within a predefined range. With each bond cycle, after attachment of the wire to the connection point, the capillary is moved out of the bond position in a predetermined horizontal direction whereby the current flowing through the drive which moves the capillary is monitored and its maximum determined.

Abstract: A method and a device which, when a pneumatic and/or hydraulic or electromechanical braking system of a vehicle is controlled, make it possible to set a second braking force on at least one wheel brake of one wheel in a defined manner in addition to the defined setting of a first braking force. The first braking force is generated by a first control unit using first hydraulic and/or pneumatic components, whereas the second braking force is generated at predefinable times as a function of the filling of an accumulator with a pressurized medium. The accumulator is a device separated from the first hydraulic and/or pneumatic components which is preferably mounted in the proximity of the wheel brakes and which is filled via a relative movement between at least one wheel and the vehicle body. It is therefore conceivable that, with the aid of a working cylinder attached to a wheel, the accumulator is filled with volume of a medium by utilizing the relative movement between wheel and body.

Abstract: The present invention relates to a device and a method for the early detection and prediction of damage to assemblies in machine plants, in particular also to mobile machine plants. For this purpose, the structure-borne sound of the machine system is sensed by a sensor (1) and output as an acceleration signal and analyzed in a digital signal processor (DSP). In this context, in order to avoid negative influences of ambient vibrations or structure-borne sounds which are not associated with the state of the machine plant, the acceleration signal is firstly transformed into the frequency domain by means of a fast-Fourier transformation, and the data obtained in this way is then transformed again into the time domain by means of cepstrum analysis so that resonance data relating to individual shock pulses (a cepstrum) is obtained in the time domain.

Abstract: A twin flow turbine housing for two intake channels (13a, 14a) separated from one another in terms of fluid technology and intended for a fluid which is to be fed under pressure to a turbine, for example of a turbocharger, consists of two substantially symmetrical half-shells (13, 14) which between them enclose a substantially flat partition (18). The two half-shells (13, 14) and the partition (18) consist of sheet metal and are welded to one another. The outer contours of the half-shells have bent-over edges (20, 20?) and notches (30?) which are engaged by extensions (30) of the partition (18), the extensions (30) projecting outwards through the notches (30?) to enable them, after assembly of the half-shells, to be welded to the edges thereof. This manufacturing technology can be used for uncontrolled turbochargers and also for turbochargers controlled by a bypass.

Abstract: In a method of estimating a bit rate (f1) of a digital signal conveyed through a SONET network between an originating node and a terminating node, the digital signal received by the originating node is processed to determine a result of a first function of the signal bit rate (f1) and a respective Tx local reference frequency (f2) of the originating node. A result of a second function of the Tx local reference frequency (f2) and a respective Rx local reference frequency (f3) of the terminating node is calculated. Finally, a result of a third function of the respective first and second function results is calculated, to derive an estimate of the signal bit rate (f4) relative to the Rx local reference frequency (f3).

Abstract: Internal combustion engines, which have an exhaust-gas turbocharger that possesses an adjustable turbine geometry, include a waste-gate bypass. When a valve controlling the waste-gate bypass malfunctions, the pressure in the intake-system branch and the exhaust-system branch may increase to an undesirably high level, which may result in component parts being damaged. To prevent this in an internal combustion engine having an exhaust-gas turbocharger, a pressure sensor is provided, which determines the pressure in or upstream from the turbine and transmits it to an electronic control unit. When the control unit determines that a preselected limiting value of the pressure has been exceeded, the turbine geometry is modified so that the turbine may be prevented from being damaged. This arrangement is provided for internal combustion engines, which have an exhaust-gas turbocharger and are equipped with, in particular, an engine-braking device.

Abstract: A Wire Bonder has a capillary clamped to a horn. An ultrasonic transducer applies ultrasonics to the horn whereby the ultrasonic transducer is controlled by a parameter P. For calibration of the parameter P, a pizoresistive sensor integrated into a semiconductor chip is used. The capillary is lowered onto the semiconductor chip and a bond force is applied to it. Afterwards, a value P1 of the parameter P is applied to the ultrasonic transducer and the output signal of the sensor is stored as the reference value URef as soon as the transient reaction is concluded. The bond force is selected great enough so that the capillary does not slide back and forth. The Wire Bonder, for example after changing the capillary, is then recalibrated in that a correction factor &ggr; is analogously determined so that the amplitude of the sensor signal assumes the value URef when the ultrasonic transducer is operated with the value P2=&ggr;*P1.
