Patent EP-0241030-A3 (EP)
IPC: F02D45/00
Filed: 1987-04-09
Abstract: Disclosed is a fuel-injection system controlling 
method and an apparatus therefor, in which a running status 
of an engine (5) is successively detected so as to 
determine a fuel-injection time on the basis of a fuel-­
injection pulse width and a quantity of pulse width 
correction in accordance with the detected engine running 
status. In the method and apparatus, there is provided 
a map (l) having a plurality of areas corresponding to 
various running statuses of the engine (5), each of said 
areas having a quantity of pulse width correction 
written therein, so that when the engine running status 
has varied from a certain one area to another one of the 
map, the boundary of the certain one area is expanded by 
a predetermined quantity, and if a current engine running 
status exists in the area encircled by the expanded 
boundary the pulse width correction quantity is not 
changed but if the current engine running status exists 
in a different area outside the area encircled by the 
expanded boundary the final fuel-injection pulse width 
is determined on the basis of the pulse width correction 
quantity written in the different area.

Patent EP-0256753-A3 (EP)
Title: Method and apparatus for preventing the copying of a video program
IPC: H04N5/76
Filed: 1987-08-04
Abstract: A video signal is modified so that a television receiver will still provide a normal color picture but which a video tape recorder will detect and prohibit its being recorded. A plurality of ordered pairs of pseudo-sync and positive pulses are added to the video signal vertical blanking interval following the normal sync pulse. A disabling circuit (22) in a video tape recorder (10) detects the modified signal. This detection may be by comparing the voltage differential between the pseudo-sync pulse tip and the positive pulse relative to the normal voltage differential between the sync pulse tip and the back porch of the blanking interval. Alternatively, the modified signal can be detected by identifying the pulse frequency of the signal in the blanking interval. A high frequency is indicative of the presence of the modified signal. A control signal (26) is produced by the disabling circuit (22) when the modified signal is present, and this disables a recording device (20). If no modified signal is detected, the recording device is enabled.

Patent EP-0384947-A3 (EP)
Title: Flexure guide for straight-line motion
IPC: F16F1/18
Filed: 1989-06-16
Abstract: An apparatus that guides an object in a straight 
line path of motion employing two leaf springs which lie 
side by side in their unflexed state in a plane 
perpendicular to the direction of motion of a moving 
part. One end of one spring is coupled to the moving 
part. The other end of the spring and one end of the 
second spring are coupled together in a free floating 
fashion. The second end of the second spring is coupled 
to the frame of the machine. As the moving part 
travels, the two springs bend in identical but opposite 
directions, canceling out any deflection or decrease in 
the lengths of the springs caused by the springs' 
flexing action. Even when the springs are flexed, they 
remain in a plane parallel to one another and 
perpendicular to the plane of the moving part. The 
moving part is coupled on one end to a conventional 
guiding device which confines the moving part to a plane 
parallel to the frame of the machine. The stiffness of 
the springs and the connection of the moving part to a 
guide allows the moving part to travel without any 
undesired tilting, and since the springs are coupled 
together in a free floating fashion, the moving part can 
travel in its straight line path without any friction.

Title: Directed hardware error identification method and apparatus for error recovery in piplined processing areas of a computer system
IPC: G06F11/14
Filed: 1989-06-30
Abstract: A computer system having trace arrays and registers 
that provide error tracing that permits entry of 
operations in a pipelined, multiprocessing environment

trace arrays in each retry domain include one master 
trace array. The master arrays store an event trace 
identification code, a cross reference event trace 
identification code, an error flag, and a cross 
reference bit. The trace arrays provide a record of the 
events occurring between the occurrence of an error and 
the completion of quiescence, when retry can be 
attempted. Error registers are used to record events in 
which errors occur during quiescence, where trace 
arrays cannot be implemented.
