Patent EP-0367624-A3 (EP)
Title: Method and apparatus for laser process control
IPC: B23K26/00
Filed: 1989-11-03
Abstract: A method and apparatus for controlling the energy of a 
laser beam from a laser (11) directed onto a workpiece 
(16) includes a photodetector (17) for generating an 
electrical signal which is proportional to the light 
reflected from the workpiece. The energy of the laser 
beam is increased from a predetermined low level by a 
modulator (12) until the photodetector (17) senses an 
abrupt change in the reflected light. This change 
represents a changed state in the workpiece material 
that is exposed to the laser beam. The energy level at 
which the change takes place is used as a reference 
level for further laser processing.

Title: Database system
IPC: G06F17/21
Filed: 1990-03-01
Abstract: A database system (51) is provided for interchanging visually-faithful renderings of fully-­
formatted electronic documents among computers having different hardware 
configurations and different software operating environments for representing such 
documents by different encoding formats and for transferring such documents utilizing 
different file transfer protocols. All format conversions and other activities that are 
involved in transferring such documents among such computers essentially are 
transparent to their users and require no  a priori  knowledge on the part of any of the 
users with respect to the computing and/or network environments of any of the other 
users.  
     All database operations are initiated and have their progress checked by means of a 
remote procedure call protocol which enables client applications to obtain partial results 
from them relatively quickly, without having to wait for such operations to complete their 
work. These database operations are forked as child processes by a main database server 
program, so the functionally of the database system may be extended easily by adding 
further database operation programs to it.

Title: Method of manufacturing a replicated magnetic reproduction medium, such as a magnetic-tape cassette provided with a music recording, and magnetic replication head and replicating arrangement for use in the method
Inventor: DUURLAND JOZEF MARIA
IPC: G11B5/86
Filed: 1993-03-11
Abstract: The invention relates to a method of manufacturing a replicated 
magnetic reproduction medium, such as a magnetic-tape cassette 
provided with a music recording, which reproduction medium comprises 
a magnetic tape (1) having a plurality of tracks extending parallel to 
one another in the longitudinal direction at specified spacings within 
certain limits from one another. The reproduction medium thus 
manufactured serves for the reproduction of the replicated signals by 
means of a magnetic reproducing head having a plurality of transducing 
gaps situated at specified spacings within certain limits from one 
another. During reproduction a specified normal tape tension within 
certain limits is sustained, resulting in a normal surface pressure 
between the tape and the head face of the reproducing head.  
     During replication the tape is moved over a head face of a magnetic 
replication head also having a plurality of transducing gaps with a 
certain spacing from one another.  
     During the replication the tension in the tape is increased relative 
to said normal tension. Another characteristic feature is that, in 
order to compensate at least partly for deviations in the positions of 
the tracks which would arise as a result of the increased transverse 
contraction of the tape caused by the increased tension, the spacings 
between the centres of the transducing gaps of the replication head are 
smaller than those of the reproducing head.

Patent EP-0671838-A3 (EP)
Inventor: MUI SHOU YEE
IPC: H04L27/22
Filed: 1995-03-06
Abstract: A data receiver receives differential phase-shift
keyed (DPSK) signals, and filters the
signal by a process including frequency
conversion, under the control of an estimated
carrier frequency (f re ), to produce a filtered
output signal which is applied to a DPSK
demodulator. The filtering compensates for the
Doppler frequency errors, and reduces the phase
error. The estimated frequency is determined by
second and third controllable filters, which
filter the DPSK carrier signal at frequencies
above and below the estimated carrier frequency
by an offset frequency which depends on the data
rate. A first frequency error estimate is made
in a processor coupled to the second and third
filters, from the ratio of the amplitudes of the
first and second filter output signals. A
second-order tracking loop is coupled to the
processor for averaging the frequency error
estimate over a predetermined number of bits, to
generate the estimate of the carrier frequency.
The Doppler frequency compensation loop tends to
correct the phase error, but may leave residual
phase errors. In an embodiment of the invention,
an estimate of the phase change per bit is
generated by a differential phase tracker coupled
to the output of the first filter, and applied to
the demodulator, in which it is used to aid in
demodulation. The estimate of the phase change
per bit may also be applied to the Doppler
frequency compensation loop for aiding in the
Doppler frequency compensation.
