Patent DE-19741662-A1 (DE)
Title: Procedure for fully selective reserve protection in cable networks with motors
Inventor: SILBERMANN WIKTOR DR ING
IPC: H02H7/30
Filed: 1997-09-16
Abstract: A procedure for fully selective reserve protection in cable networks switches the supply in the case of multiphase short-circuits when the insulation might ignite. Out of three rectified secondary currents of the supply, one chooses the maximum current and the ratio of this to the rated input current is measured.  If the ratio is greater than between 5 to 7, a signal for switch-off after a certain trip time is instigated. The trip time is between 0.1 and 0.6 seconds. If the ratio is less than 5 but greater than between 1.25 to 1.5, that value is stored and the switch-off signal is given after another trip time proportional to the inverse square of the ratio.
Patent DE-19751534-A1 (DE)
Inventor: PARK CHAN-SIK
IPC: G02B6/00
Filed: 1997-11-20
Abstract: An optical attenuator includes an optical fibre 12, the optical properties of which include at least one discontinuity 10 which interrupts the total internal reflection conditions of the optical fibre, so as to attenuate light transmitted through the optical fibre. The discontinuity 10 may be caused by variations in the refractive indices of a core layer and a clad layer of the optical fibre 12 e.g. gratings which may be formed at intervals of 500-600nm by a phase mask process. The gratings may be formed over a distance of 1-10cm. The attenuator may be for use at wavelengths around 1550nm. The optical fibre may be in a tube so as not to be influenced by external conditions.

Title: Determining when to discontinue auxiliary heating of catalyst from cold start
Inventor: SCHNEIDER STEFAN DR
IPC: B01D53/94
Filed: 1997-12-04
Abstract: The criterion indicating achievement of initiation- or light-off temperature for catalytic action, is the time integral of thermal energy supplied by exhaust gases to the catalyst (4). Additional heating is shut off, once energy supplied exceeds a given threshold (SW1).  Preferred Features: Thermal energy supplied is determined from: exhaust gas mass flowrate, its specific heat at constant pressure and the exhaust temperature upstream of the catalyst. Exhaust mass flowrate is determined from the inlet air mass flowrate induced directly by the engine, and from the secondary air mass flowrate. The latter is introduced by the secondary air injection system (8, 9, 16). A correction included, takes into account the quantity of fuel introduced. The calculated total energy supplied to the catalyst is corrected for convective heat losses, taking into account vehicle speed. For this purpose, corrections in terms of speed are stored in e.g. a look-up table in computer memory. A sensor (11) measures exhaust temperature. Alternatively its temperature is deduced from stored data, in terms of measured stoichiometry, air inlet flowrate, and ignition timing. In a similar method, the temperature reached by the catalyst is deduced from its measured inlet and outlet temperatures, to indicate when additional heating can be discontinued. A further related method is based on direct measurement of the catalyst substrate temperature. For each of the foregoing methods, the mathematical relationships are set out.

Title: Motor vehicle airbag cutout circuit
Inventor: PAGEL ERNST OLAV DR
IPC: B60R21/01
Filed: 1998-01-16
Abstract: With the airbag functioning correctly, a measurable value between two input-connected outputs of a controller (6) shows a preset value in a circuit with a switch (12) in the lines from controller to airbag to short-circuit the air bag inputs so as to cut out the airbag. At the same time, the switch connects the controller outputs to a component (16) having a preset value corresponding to that of the airbag. The first contact (14) of the switch (12) connects to the airbag input and the first connection of the component (16).   The second switch contact (18) is connected to line (20) leading from the controller output to the second airbag input and the third switch contact (22) connects to the second controller and second component (16) connection. Thus with the airbag coupled up, first (14) and third (22) contacts are joined as against when the airbag is cut out in which case the first contact (14) is connected to the second contact (18).

Patent DE-19811567-A1 (DE)
Title: Precision voltage generator for generating DC reference voltage
Inventor: YOSHIDA HARUO
IPC: G01R1/28
Filed: 1998-03-17
Abstract: The precision reference voltage generator has a VCO (4) which has a fixed and precise relationship between a frequency of an oscillating signal and a voltage fed to the VCO. The generator has a reference frequency oscillator (6) for generating a reference frequency signal with an accuracy and stability higher than for the reference voltage to be generated. A phase comparator (5) detects a phase difference between the oscillation signal of the VCO and the reference frequency signal. A low pass filter (7) smooths a detection signal from the phase comparator as an indication of the phase difference. An amplification adjustment circuit (8) amplifies a signal from the low pass filter. A voltage adder (3) supplies a sum of voltages from the amplification adjustment circuit and an offset voltage to the VCO. A phase locked loop (PLL) is formed from the phase comparator, the low pass filter, the amplification adjustment circuit and the voltage adder. The phase locked loop brings the phase difference to zero by regulating a control voltage applied to the VCO. The control voltage is output as the reference voltage.

Title: Multiple carrier signal transmission method for parallel transmission over several sub channels
Inventor: KAMMEYER KARL-DIRK
IPC: H04L27/26
Filed: 1998-06-23
Abstract: A utilization scheme is determined which specifies the use of sub channels for data transmission by assigning channels which comprise only noise as unused channels, and channels on which profit signal is received as used channels. The method involves transmitting data in parallel in form of a signal on several sub-channels over a transmission path between a transmitter and a receiver. A transmission function is determined for each sub-channel in the receiver. The sub-channels are rated according to their respective transmission function with respect to their fitness for a data transmission, and a first amount of the best sub-channels are released for the data transmission, while the remaining sub-channels are blocked.   The receiver determines a respective utilization scheme which specifies the sub-channels with data and the sub-channels without data, by assigning channels which comprise only noise as unused channels, and channels, on which a profit signal is received, as used channels. The signal transmission method is preferably an Orthogonal Frequency Division Multiplexing method.
