Patent EP-0300778-A3 (EP)
Title: Ring shaped local area network
IPC: H04L12/437
Filed: 1988-07-21
Abstract: A ring-shaped network for an aircraft communications 
control system transmits both digitised audio signals and 
control data in small packets of equal length from node to 
node. Each active node comprises a packet-long register 
(RX) permanently connected in the ring (A), the node 
having means for labelling each packet it transmits as 
either full or empty, and having means for testing whether 
the packet being received is full or empty. The 
transmission of a new packet of data by that node is 
prevented unless the packet as received is empty.

Title: Hand rail safety bar
IPC: E04F11/18
Filed: 1988-12-07
Abstract: A stairway safety bar 10 comprises a housing 14 slidable on 
a rail 18 which is fixed to a wall 20. The bar 12 
extends across a stairway and may be pushed up or down the 
stairway by a person ascending or descending. The 
housing 14 includes a locking mechanism (22, 26) which 
locks on to the rail 18 thereby preventing further 
movement of the bar and a force which exceeds a 
predetermined limit is applied to the bar. The bar can 
be pushed by an elderly or disabled person, but should the 
person fall the additional force applied will lock the 
mechanism and prevent the person falling down the stairs.

Title: Lamina for the rotation of the direction of polarisation in an optical fibre and its application
IPC: G02B26/00
Filed: 1989-06-19
Abstract: A rotating lambda/2 lamina is accomplished with optical 
fibres by applying transversally to the fibre itself at least 
three sinusoidal forces (F₁, F₂, F₃; F'₁, F'₂, F'₃) having 
constant maximum amplitude, which act in radial directions at 
120° one to the other and are out of phase over time by 120° 
one from the other.  
     Among its possible applications there is particularly 
envisaged that related to optical fibre frequency modulators-translators, 
in which one or more rotating lambda/2 laminas 
are alternated with as many static lambda/2 laminas, 
all made of optical fibres.

Patent EP-0351209-A3 (EP)
IPC: G06F9/44
Filed: 1989-07-12
Abstract: A method is disclosed for enforcing referential constraints on a 
record-by-record basis, immediately before or after each record is 
manipulated and while the record is still accessed, significantly 
improving the system's performance. Each record is visited only once to 
do both the constraint checking and the manipulation (insert/update/­
delete). If the constraint checking fails, then the entire relational 
operation of which the record manipulation is a part is backed out. For 
insertions, each record is first inserted 30, and then constraints 
respecting the record are enforced 32,34. For updates, the record is 
updated 48 after constraints respecting the record's primary key are 
enforced 40,42, and before constraints respecting its foreign key(s) are 
enforced 44,46. Deletions are performed 52 before the constraints on 
the deleted record are enforced 54,56. Cascade deleted 58 are handled 
recursively 60. The method correctly processes cyclic constraints and 
self-referencing rows without special handling.

Title: Count-locked-loop timing generator
IPC: G06F7/68
Filed: 1989-08-24
Abstract: The present invention is an all digital 
timing and address generator (10, 20) which 
automatically adjusts its output pulse intervals to 
fit within the duration of periodic input pulses. The 
intervals are always synchronous with the leading 
edges of the input pulses, and their number within the 
duration of a periodic input pulse is selectable in 
increments of one. The generator (10, 20) uses direct 
digital feedback to control its output timing for 
changes in input pulse width, and employs an integer 
time mark to prevent "unlocking" on non-integer width 
input pulses.

Title: Regionally adaptive imaging techniques
IPC: A61B6/00
Filed: 1990-02-13
Abstract: A first regionally adaptive imaging technique, for enhancing the contrast of a 
digital image, employs an adaptive histogram equalization technique in which the 
histogram associated with a contextual region is low pass filtered, prior to developing 
the mapping function, of original pixel intensity to adjusted pixel intensity, from the 
histogram. A second technique for enhancing the contrast of images within a smooth 
background employs a regionally adaptive filter in which the intensity of selected 
pixels are adjusted in accordance with a transformation which is a function of the 
mode of pixel intensities, and deviations from the mode of pixel intensities, within a 
contextual region corresponding to the selected pixel.

Title: Method for controlling polarizations of signal lights in an optical frequency division multiplex coherent communication system
IPC: H04B10/63
Filed: 1990-03-15
Abstract: Frequency division multiplex signal lights (1) are 
propagated through an optical fiber (10), and polarizations 
of the lights are collectively controlled by a 
polarization controller (2). The polarization-controlled 
signal lights are received separately in receiving 
systems (4, 5, 6), including optical heterodyne or homodyne 
receivers (11). In the collective polarization control, a 
step is selected from steps of controlling relative 
polarization states of local oscillation lights to 
coincide to each other, receiving a control signal from 
one of the receiving systems which receives a signal 
light of a frequency to be allocated in the center of a 
frequency band of the signal lights or the vicinity 
thereof, and dividing the frequency division multiplex 
signal lights into plural groups, thereby controlling 
polarizations collectively in each of the plural 
groups. One of the polarizations of the signal lights 
may be orthogonal to the others, and one of the 
polarizations of the local oscillation lights may be 
orthogonal to the others correspondingly.

Title: Measurement circuit for detecting a current
IPC: G01R1/36
Filed: 1991-04-22
Abstract: 2.1 When checking devices of protection class II, the stray current must be measured between contactable conductive parts and earth. If there is a low-resistance connection to the mains, a current limiting element (R1, S1) protecting the measuring instrument will respond and there is then no display signalling the fault case. 2.2 In order to obtain an overcurrent indication in spite of the current reduced in the measuring circuit (R1, R2, V3, V4, R5), a shunt branch (V1, V2, R3, R4) is formed which bypasses the current limiting element (R1, S1) and, when a limit value is exceeded, supplies the input (C, D) of a measuring device (M) with a signal which produces an overflow indication. 2.3 The measuring circuit is basically suitable for all current measurements in which a hazardous voltage must be expected as is the case, for example, in stray current measurements. <IMAGE>

Filed: 1991-12-05
Abstract: For implementing a parallelized algorithm for solving the key 
equation for the decoding of a linear algebraic code, a computational 
loop has one branching condition that branches into two straight-line 
loops. One of these loops executes three multiplication operations and 
the other executes five multiplication operations, 2t iterations of

loops are coupled so that during each successive 2t iterations, four 
multiplication operations are executed simultaneously in pairs, the 
fifth multiplication operation in the other loop being paired with a 
multiplication operation in the next iteration of the one loop. During 
one of the paired multiplication operations an inverse table look up 
operation is executed, and during another of the multiplication 
operations an addition operation is executed.
