Patent EP-0303352-A3 (EP)
Title: The method of optically measuring relative angular movement
IPC: E21B47/022
Filed: 1988-07-07
Abstract: Relative angular movement between two linear members is 
detected by shining light from a light source (11) through a 
triangular mask (12) in one member onto a mirror (10) in the other 
member and reflecting the image of the triangular mask onto a linear 
array of detectors (15). Movement between the two members causes 
different detectors in the array to be illuminated and the position 
and number of detectors illuminated determines the X and Y axis of 
movement to enable the relative angular movement of the two members 
to be calculated.

Patent EP-0369365-A3 (EP)
Title: Monolithic skew reduction scheme for separately clocked data transfers
IPC: G06F13/42
Filed: 1989-11-11
Abstract: A system for reducing skew in the parallel 
transmission of digital data slices is provided. The 
system includes a transmitter unit comprising a 
plurality of transmitter memory devices. Control logic 
provides a strobe signal to each transmitter unit memory 
device to implement the transfer of a desired number of 
data characters from the transmitter unit to a receiver 
unit. Both its associated data slice and the strobe 
signal are transferred from each transmitter unit memory 
device to the bus via an associated transmitter unit bus 
driver. Each data slice and its associated strobe 
signal are then transferred from the bus to a 
corresponding receiver unit memory device via a 
corresponding receiver unit bus receiver device. Each 
receiver unit memory device includes means for 
generating a "receiver-full" status signal that 
indicates that all data slices transferred from the 
corresponding transmitter unit memory device have been 
received. These "receiver-full" status signals are 
monitored and a "transfer-done" status signal is issued 
when all data slices transferred from the transmitter 
unit have been received by the receiver unit. Skew 
within a particular transmission path is compensated for 
by providing a controlled delay path for the clock 
signal in each device within that path.

Title: Multifunction memory for digital television
IPC: H04N5/45
Filed: 1989-03-06
Abstract: A digital television processing section capable 
of picture enhancement, progressive scanning, and multiple 
picture-in-picture processing is provided. The preferred 
digital television processing section preferably comprises 
a picture enhancement processor (PEP), a progressive scan 
processor, a picture in picture processor, at least one 
multiplexing means, and a common memory means. The PEP 
broadly comprises a parameter control means, a memory input 
select means, and mixer for obtaining current video data, 
delayed video data from the common memory, and control 
information from the control means, and for processing the 
obtained data and information to provide a signal to the 
progressive scan processor. In various modes of operation, 
the mixer also provides the signal to the memory input 
select means which forwards the information to the common 
memory. The common memory is used as a field delay device 
and feeds a delayed signal forward to the progressive scan 
processor. The progressive scan processor then utilizes 
the current signal and the delayed signal to provide a non-­
interlaced display. The delayed signal from the common 
memory may also be fed back to the mixer of the PEP so that 
noise reduction and/or cross-color effect reduction may be 
accomplished or so that stored pictures may be displayed. 
The picture-in-picture (PIP) processor together with a 
first multiplexer permits main and secondary (PIP) video 
data to be supplied as current video data to the PEP. Or 
if desired, up to nine PIPs may constitute the video field.

Title: Image recording apparatus
IPC: G03F7/00
Filed: 1989-07-06
Abstract: An image recording apparatus for recording an image 
corresponding to an original on a continuous image recording 
medium such as a photosensitive microcapsule sheet (37). The 
apparatus comprises exposure means for exposing the 
recording medium to light in an exposure zone (3-12) to form a 
latent image on the recording medium, developing means (20) for 
developing the latent image into a visible image, first 
feeding means (17) disposed downstream of the exposure zone for 
positively feeding the recording medium, and second feeding 
means (41, 42) disposed upstream of the exposure zone, the second 
feeding means being idly rotatable by the recording medium 
while the recording medium is being fed by the first feeding 
means. While the recording medium is being fed along the 
sheet path, it is exposed to light focused by exposure 
means. During image exposure, the recording medium is held 
flatwise against an exposure table (19) to allow accurate 
formation of the image thereon. To keep the recording 
medium flatwise against the exposure table, the recording 
medium is tensioned (44) near the exposure table.

tive to the sensor means (1) with a composant of movement in a 
direction away from the sensor means (1) and at least one compo­
sant of movement perpendicular to said direction, before being 
released from the vehicle. The limiting surfaces (10, 11) of the

Title: Fuzzy rule generator
IPC: G06N5/04
Filed: 1990-04-17
Abstract: A fuzzy rule generator for generating fuzzy rules, 
comprising: a selection unit for selecting two or more 
sets of rules from a plurality of basic sets of rules 
which may be stored in memory; and a control unit for 
generating a new set of rules by carrying out a 
synthetic arithmetic operation based on a predetermined 
set of rules for synthesis. This process of synthesis 
may simply consist of addition or subtraction. 
Thereby, a new set of rules can be easily generated by 
carrying out a simple arithmetic operation for each 
application. Therefore, generation and modification of 
rules are simplified and speeded up, with additional 
benefits arising from an efficient utilization of 
existing sets of rules. Further, by imposing a 
constraint on the newly synthesized set of rules 
manually, automatically or by a combination of both 
according to a predefined algorithm, it is possible not 
only to ensure the stability of the system but also to 
obtain desired control characteristics. If desired, 
the newly created sets of rules may be added to the 
library of the basic sets of fuzzy rules.

Title: Sulphur treatment of magnesium-contaminated fe-cr-al alloy for improved oxide whisker growth
IPC: C23C8/10
Filed: 1991-03-04
Abstract: A method for producing aluminium-containing ferritic stainless steel from a magnesium-contaminated melt is disclosed, such that the steel is suitable for growing oxide whiskers on a surface thereof, so as to cover said surface. The method comprises adding sulphur to the contaminated melt in an amount sufficient to increase the sulphur content to not less than 1.3 times the magnesium content, whereupon the sulphur reacts with the magnesium to render the magnesium inert and thus prevent it from inhibiting oxide whisker growth. The method also preferably comprises an addition of titanium, zirconium or hafnium in amounts sufficient to react with any residual sulphur present in the melt in excess of the amount required for complete stoichiometric reaction with the magnesium present in the melt, thereby mitigating the adverse effect of free sulphur in the steel on oxide adhesion to the steel.
