Patent EP-0522797-A3 (EP)
Title: Synchronous digital signal to asynchronous digital signal desynchronizer
IPC: H04L7/00
Filed: 1992-07-02
Abstract: Improved jitter performance is realized in a desynchronizer for 
obtaining an asynchronous signal, e.g., a CEPT-4 signal, from a received 
synchronous signal, e.g. a SDH STM-1 signal. The improved jitter performance 
results from employing a unique gap generator (103) which causes gaps in a received 
data signal to be spread regularly in time, and allows for almost continuous control 
by numerical techniques of the phase of a smooth output clock being generated. 
Phase control is obtained by employing a filtered version of the difference between 
the actual number of data bits in the received digital signal and the expected nominal 
number.

Patent EP-0496693-A3 (EP)
Title: Method and equipment for monitoring and controlling apparatus for injecting
IPC: A23B4/28
Filed: 1992-01-24
Abstract: In order to regulate the amount of injected brine in a disarranged flow of meat items, two flow scales (8A, 8B) are used which weigh the quantity on arrival and on leaving from an injector (2). In order to do this the results from the entering scales are delayed until they are synchronous with the outlet scales, whereupon a yield percentage can be calculated. This yield percentage is then fed to the injector which perhaps will correct its operating parameters. The data collected can make the basis for a printout of a certificate for a well-defined batch of items. An equipment comprises two identical weighing units (4) with flow scales (8) and a belt conveyor (10, 12) before and after, where the speeds of the belts are identical, whereby an accurate weighing of the item flow is achieved. <IMAGE>
Patent EP-0571016-A3 (EP)
Title: Method of and device for recording information on a record carrier having a recording layer which, when heated, undergoes an optically detectable change
Inventor: SPRUIT JOHANNES HENDRIKUS M
IPC: G11B7/125
Filed: 1993-05-07
Abstract: When recording information on a record carrier (1) having a recording 
layer (2), the recording layer (2) is scanned by means of a radiation beam (71) whose 
radiation power has a pulsatory variation. As a result of the heating produced by the 
radiation pulses, the recording layer (2) undergoes an optically detectable change. A 
write signal generating circuit (78) converts an information signal v(t) into a write 
signal g(t) which has a pulsatory pattern, which pulse pattern comprises pulses of a high 
signal level which alternate with intervals of a low signal level. A control circuit (78) 
sets the power of the radiation beam (71) at a value fixed by the signal level of the 
write signal. The signal level within the pulses decreases, while the signal value of the 
write signal g(t) increases in the intervals. As a result, the influence exerted by previous 
radiation pulses on the temperature at the scanning area (73) is compensated for.

Title: Recording and reproduction of television signals
Inventor: KANOTA KEIJI
IPC: H04N7/00
Filed: 1995-11-03
Abstract: The television signal recording/reproducing system digitally records and reproduces television signals composed of a luminance signal, a chrominance signal and a resolution compensation signal included in predetermined television scanning lines. The system includes a Y/C separating circuit (110) for separating the luminance signal Y from the chrominance signal C. The luminance signal Y and the resolution compensation signal are combined onto a first signal line. A demodulating circuit (130) demodulates the chrominance signal into a color difference signal and outputs the demodulated signal to a second signal line. A digital video signal recorder (106) digitally process the signals on the first signal line separately from the signals on the second signal line and records the digitally processed signals. In this manner, the resolution compensation signal is processed with the luminance signal and the resolution compensation signal can be accurately recorded.

Patent EP-0732427-A3 (EP)
IPC: C30B15/30
Filed: 1996-03-15
Abstract: According to the present invention, in the growth of an oxide single crystal 
or a compound semiconductor single crystal such as GaAs single crystal by 
the CZ method or LEC method, the tendency of concave solid-liquid interface 
shape at the periphery of the growing crystal can be suppressed to prevent polycrystallization 
without localized heating of the solid-liquid interface, while 
well controlling the diameter of the growing crystal even when using a crucible 
with a larger diameter, thus improving the yield of crystal on a commercial 
scale. The feature consists in that the end of a cylindrical body having an 
inner diameter of larger than the predetermined diameter of straight part of 
the growing crystal is immersed in the raw material melt or liquid encapsulant 
and the crystal is pulled while preventing the shape of the solid-liquid interface 
from becoming concave by controlling the rotation rate of at least one of 
a crucible holding the raw materialmelt, the growing crystal and cylindrical 
body.
Patent EP-0741496-A3 (EP)
Inventor: CHEN TSUHAN
IPC: H04N7/26
Filed: 1996-04-17
Abstract: Motion video is represented by digital signals. The
digital signals can be compressed by coding to reduce
bitrate and thus save time and expense in transmitting
and reproducing the video. The present invention is a
system and method for reducing the amount of information
required to satisfactorily reproduce video signals by
distinguishing more pertinent portions of the video from
less pertinent portions. In particular, edges are
detected based on amplitude variations in the luminance
characteristic of the picture elements. Sharp edges are
deemed to be "focused". The portion of the video frame
between the focused edges is deemed to be focused, as
well. A template is created corresponding to the focused
portion. A signal corresponding to the outline of the
template is combined with the original frame signal to
create a segmented frame signal. When motion detection
information is available, a motion-based template may be
created and intersected with the focus template. A
signal corresponding to the outline of the intersected
template may be transmitted with the frame signal as the
segmented frame signal.
Patent EP-0777041-A3 (EP)
Inventor: SCHNEIDER MATTHEW L
IPC: F01M11/10
Filed: 1996-11-28
Abstract: In a closed crankcase ventilation system, crankcase
gases are allowed to flow through a venturi (10) which
includes high pressure and low pressure taps (24 and
28). The high and low pressure taps (24) and (28) are
coupled to a differential pressure transducer (30)
which produces an output that is proportional to the
volumetric flow of crankcase gases through the venturi
(10). The use of a venturi (10) in conjunction with a
differential pressure sensor (30) offers a low
resistance path for the flow of crankcase gases and
allows continuous monitoring of blow-by without
exceeding the operating pressure limitations of
various oil seals. Such a sensor (30) is particularly
suited for closed crankcase ventilation (ccv) systems,
as it doesn't require venting of crankcase gases to
the atmosphere, but works well in open crankcase
ventilation systems also.
Patent EP-0782252-A3 (EP)
Inventor: EMBREE MILTON LUTHER
IPC: H03F3/30
Filed: 1996-12-05
Abstract: The invention is an operational amplifier (50) having an output stage
(52) for enhancing the output driver capability near the negative source voltage (66).
The output stage of the invention includes a voltage detector (M14) in combination
with a current redirector (82) or redirecting arrangement. The voltage detector
(M14) converts the voltage difference between the amplifier output (76) and the
input to the output stage of the amplifier to a control current, which is redirected at
the positive source voltage and applied to the negative output driver (84). The
current redirector (82), which is operably connected to the voltage detector, allows
the amplifier output to be driven at full rated current (e.g., approximately 40mA)
close to the negative source voltage (e.g., within approximately 1.5 volts) while
maintaining an output configuration appropriate for stability.
