Patent EP-0364285-A3 (EP)
Title: Television transmission
IPC: H04N7/169
Filed: 1989-10-13
Abstract: The presence of random noise, interference, 
multipath, and imperfect frequency response in 
terrestrial broadcasting channels, and of pervasive 
low-level reflections in cable systems, degrades the 
quality of television reception. These effects tend to 
reduce the difference in quality between that of NTSC 
and that of various advanced television systems, as 
actually delivered to the home via such channels. 
Several methods are disclosed for dealing with these 
effects, and thus to preserve the improved quality made 
possible by currently proposed EDTV and HDTV systems. 
Automatic channel equalization is used for first-order 
correction of multipath and frequency distortion. A 
scrambling method is described that transforms all 
remaining degradations to additive random noise, which, 
for a given noise power, is of minimum visibility. 
Random noise, whether additive or produced by scrambling 
of other defects, is suppressed by adaptive modulation. 
If the channel SNR is high enough, some digital data can 
be transmitted in addition to the analog data by a 
method called "data under". The methods are applied to 
a receiver-compatible system that utilizes a very 
low-power 3-MHz augmentation channel as well as to a 
bandwidth-efficient 6-MHz system that is not receiver 
compatible. One version of the latter system can be 
operated at such low SNR that it may be possible to 
utilize the taboo channels.

Patent EP-0402566-A3 (EP)
IPC: G01R31/11
Filed: 1990-02-13
Abstract: In this method it is provided to write the recording of a fault pattern and a healthy pattern one above the other via a digital memory and to use pulses which have the same amplitude and curve shape. For this purpose, an arc is generated at the fault location and when the capacitor is discharged through the arc current to a voltage below the ignition voltage of the fault location, the existing residual charge of the capacitor is fed to the cable in the manner of a pulse and the reflected wave is detected via a channel of the digital memory. Subsequently, after disconnecting the cable and recharging the capacitor to a voltage below the ignition voltage of the fault location, a new discharge will occur via the cable, the reflected wave produced being recorded via a second channel of the digital memory. When the two recordings are written one above the other, the point of deviation is used for determining the fault location. <IMAGE>

Patent EP-0459752-A3 (EP)
IPC: H04L12/56
Filed: 1991-05-28
Abstract: Transmit and receive data are stored in buffer regions defined in first and second memories of a system residing on a network. The buffer regions are pointed to by multiple descriptor rings that are also stored in the memories. In accordance with one aspect of the invention, the two memories reside on separate busses connected to a common buss containing a processor. The processor communicates with one or the other of the memories using a handshaking protocol. In accordance with another aspect of the invention, receive data incoming to the system is scattered among multiple descriptor rings. A further aspect splits a frame among multiple descriptors depending on a characteristic code carried by the frame, e.g., in a frame control field. The size of the first descriptor, smaller than that of the others, is programmed to correspond to the size of the header of each frame. Synchronization between headers and data of a frame is maintained by a frame number stored in each descriptor. Another aspect prevents blocking of the receive path upon occurrence of a blocked receive descriptor ring. One application of the invention is in a fiber distributed data interface (FDDI). <IMAGE>

Title: Method for controlling a stepping motor
Inventor: RISS UDO DR-ING
IPC: H02P8/00
Filed: 1992-07-09
Abstract: In order to drive a stepping motor (1, 2) which can be driven in main steps and in intermediate steps within each main step, the motor (1, 2) is driven into a defined zero position for starting, using a phase current combination which corresponds to the defined position. Thereafter, a test is carried out via a reference switch (4, 5) which is arranged between the mutually moving motor parts (1, 2) to determine whether the motor (1, 2) is in the defined position. The defined position is reached when the reference switch (4, 5) triggers. If said switch does not trigger, the motor (1, 2) is driven so that it carries out a movement whose magnitude is equivalent to a plurality of main steps and is then once again driven with the abovementioned phase current combination. The reference switch (4, 5) is then interrogated again. This is repeated until the reference switch (4, 5) triggers and the defined position is hence reached. <IMAGE>
Patent EP-0528234-A3 (EP)
Title: Data processing system for generating data bits based on stored data
IPC: G06F12/16
Filed: 1992-07-31
Abstract: A memory system that provides extra data bits without utilizing storage capacity. A first data word is fetched from memory (10) and corrected to remove any single-bit errors. A second data word (which is a subset of the first data word as corrected) is then fetched, and new data correction bits (parity or ECC check bits) is generated for the second data word. Both the second data word and the newly-generated data correction bits are output. This structure amortizes the expense of in-system data correction over a greater data output, and over a smaller storage capacity relative to the data output. <IMAGE>
Patent EP-0536932-A3 (EP)
Title: Closed loop launch and creep control for automatic clutch
Inventor: SLICKER JAMES MELVIN
IPC: B60W10/02
Filed: 1992-09-30
Abstract: The system has an engine speed sensor producing a signal corresponding to the rotational speed. A reference speed generator produces a signal based on the speed sensor and the throttle signal, to select either launch or creep values. A transmission input speed sensor is connected to the output shaft of the friction clutch. An actuator controls the engagement/disengagement of the frictional clutch in response to a controller, which utilises the sensor signals. An algebraic summer forms a difference signal between the reference speed and the transmission signal and a compensator causes the clutch to be partially engaged such that the transmission input speed signal asymptotically approaches the reference signal.
