Patent EP-0368189-A3 (EP)
IPC: H04B3/23
Filed: 1989-11-06
Abstract: The present invention provides a technique for data 
detection signal processing for removing echo 
interference and/or distortion from a received 2B1Q 
coded signal. According to the preferred technique, the 
received 2B1Q signal Q, where q=(-3, -1, +1, +3), is 
shifted one bit to the left to generate a corresponding 
shifted symbol alphabet S, where S=(-2, 0, +2, +4). The 
shifted received signals are then processed through a 
transversal filter. That is, the signal is provided to 
a delay line which is tapped at intervals corresponding 
to the symbol width of the received signal. Each tap 
along the delay line is connected through an amplifier 
to a summing device that provides an output y(n), where 
   
     The tap gains, or coefficients a j , are set to subtract 
the effects of interference from symbols that are 
adjacent in time to the desired symbol.  
     In an adaptive embodiment of the invention, the 
output y(n) resulting from the convolution between the 
transmitted symbols s(n) and the gain coefficients a j . 
The output of the transmission channel and the filter 
output y(n) are then processed in accordance with a 
convergence algorithm to develop an error feedback 
signal which is used to update the gain coefficients a j .

Patent EP-0380089-A3 (EP)
Title: A relay driving circuit for a latching relay
IPC: H01H47/22
Filed: 1990-01-25
Abstract: A relay driving circuit for a latch-in type magnetic 
relay having an excitation coil (L) to selectively provide a set 
current to the coil for making the relay into a set position 
and a reset current of opposite polarity to the coil for 
making the relay into a reset position. A capacitor (C) is 
provided between input terminals of the circuit in series 
with the coil to be responsible for discharging the reset 
current. A set switch (20) is connected in circuit in series 
with the series combination of the coil and the capacitor, 
while a reset switch (30) is connected across the series 
combination. An input voltage level detector (10) is provided to 
make the set switch conductive in response to the input 
voltage being detected to exceed a trigger level, thereby 
applying the input voltage to the excitation coil and the 
capacitor to provide the set current. Upon the input 
voltage decreasing below the trigger level, the detector 
makes the reset switch conductive to allow the capacitor to 
discharge the current in the opposite direction through the 
excitation coil as the reset current. The circuit is 
characterized to include a disable switch (40) which, in response 
to that the capacitor is charged up to a level sufficient to 
flow the reset current, makes the set switch non-conductive 
to thereby prevent the voltage developed across the 
capacitor from reversely applying to the input voltage level 
detector. Accordingly, the detector can correctly responds 
only to the input voltage and not to the voltage of the 
 
 
capacitor so that it can make the reset switch conductive 
immediately upon the input voltage being decreased below the 
trigger level without making the set switch conductive in 
response to the accumulated voltage of the capacitor.

Title: Split extrusion die assembly for thermoplastic materials and methods of using the same
IPC: B29C48/12
Filed: 1990-01-29
Abstract: A die spool (10) for the extrusion of thermoplastic 
materials includes an axially split elongate spool 
body so as to be separable into first and second 
spool segments. The spool segments collectively 
establish the spool body and also define an axially 
oriented extrusion cavity through which thermoplastic 
material is conveyed. An alignment system ensures 
that only a single orientation of the extrusion axis 
is possible when the die spool is coupled to another 
similar die spool (or to an extrusion die associated 
with an extruder). A die spool assembly (10) may 
therefore be provided which is comprised of a number 
of individual die spools (10a,10b,10c). Preferably, a decreasing 
temperature gradient is established within the 
extrusion cavity of the die spool assembly (10) (as may be 
accomplished by controllably operating electrical 
resistive heater elements) so as to at least 
partially solidify the thermoplastic extrudate 
therewithin. During extrusion start-up, a lower die 
spool segment (36a,36b,36c) is employed to support an initial 
length of thermoplastic extrudate, with the upper die 
spool segment (34a,34b,34c) being mated therewith (thereby 
collectively defining the extrusion cavity) once the 
extrudate extends beyond the downstream end of the 
lower segment. In such a manner, manual conveyance 
assistance along the extrusion axis may be imparted 
to the extrudate during start-up.

Abstract: A phase locked loop is disclosed in which a 
digital audio signal is recorded in synchronism with a 
video signal and a sampling frequency of the digital audio 
signal is reproduced in reproduction mode. 
The phase locked loop comprises a phase 
comparator (106), a low-pass filter (107), a VCO (108) and 
a frequency divider unit (601) which is switched by the number 
of the digital audio signal recorded for each vertical 
sync period (or 1/N thereof) of the video signal, so that 
a sampling frequency of the digital audio signal having no 
relationship of integral ratio with a vertical sync 
frequency Fv of the video signal is reproduced from the 
same frequency Fv. The reference input to the phase 
comparator (106) is delayed by a predetermined time in 
accordance with the number of the digital audio signal, 
with the result that the sampling frequency reproduced has 
no period error to the extent that the reference input has 
no period error.

Title: Method and apparatus for correlative digital signal processing using systolic arithmetic circuit
IPC: H04B1/713
Filed: 1992-02-29
Abstract: In a method for the correlative digital signal processing at the receiver end in a system for transmitting digital information having fixed-duration signal shapes, multiplications of received signal X and reference signals Yi and accumulations of the products are carried out in the course of n clock steps in a systolic arithmetic circuit (4). During the time when the input (1) of the arithmetic circuit (4) receives digitised samples X of the received signal, the input (2) is supplied with suitable reference values from a digital memory (9) which is connected to the address counter (10), and the accumulation values Ai already accrued are input at input (3) for adding up further products X.Yi. With the aid of a synchronising device (14), the digital circuit (8) controls the appropriate provision of the reference values Yi from the memory (9) and ensures that the registers of the arithmetic circuit (4) are emptied at the beginning of each signal shape to be received, and that the n accumulation values are successively read out of the register Rn of the arithmetic circuit (4), with open feedback loop from the output (6) to the input (3), via the connection (7) at the end of each signal shape duration and are processed further so that the received digital information items become available at the output (13) of the digital circuit (8). Using a device according to the method described, it is possible to build up matched filters operating purely digitally for signal shapes of a large variety in a simple and perfectly reproducible manner. Because of the low costs of such a structure, which can be achieved by large-scale integration, for example power supply grids can be opened up as a reliable medium for transmitting digital information by means of a band spreading technique, for example by means of frequency shift keying, for a large variety of applications. Complete modems consisting of transmitter and receiver can be implemented which can be widely adapted to various requirements, for example with respect to data rate and resistance to interference, due to their purely digital mode of operation.
