Patent EP-0391546-A3 (EP)
IPC: G09B9/052
Filed: 1990-03-12
Abstract: A testing method and apparatus for determining the reaction 
time of machine operators, especially drivers of automotive 
vehicles. A series of images are projected onto a viewing screen 
to be observed by a student at a student station. The images 
comprise one or more visual depictions of various operating 
conditions, including non-threatening and threatening conditions. 
After presenting a sequence of non-threatening conditions images, 
an "action cue image" representing a threatening condition is 
projected. The elapsed time between the projection of the action 
cue image and the initiation of the required response of the 
student is measured to derive the student's reaction time, in terms 
of seconds or distance traveled at a specified speed.

Patent EP-0479230-A3 (EP)
Title: Recovery method and apparatus for a pipelined processing unit of a multiprocessor system
IPC: G06F11/00
Filed: 1991-10-01
Abstract: The pipelined central processing system (CSS) units of a multiprocessor system are tightly coupled to connect in common to a system bus for sharing main memory and input/output controllers/devices. The CSS includes several circuit boards for the different VLSI circuit chip pipelined stages and associated control circuits in addition to the bus interface unit (BIU) circuits. Each board includes one or more unusual event (UEV) detector circuits for signaling when the behavior of a stage is abnormal. The UEV fault signals from each board are collected by the BIU board. When a UEV fault is detected, the BIU board circuits prevent any further communications with the system bus and broadcasts the UEV fault signal to the other boards causing the different pipelined stages to emulate the completion of the instructions within the pipeline thereby flushing it. It is thereafter placed in a nonpipelined mode. Control circuits execute a UEV handler microcode routine which reads the contents of syndrome registers included on each board containing the UEV indicator states in addition to error signals into register file working locations. The UEV signal is then cleared enabling the BIU to resume communications with the system bus. A unique trap is constructed for signaling the operating system software if the UEV fault was external or internal to the CSS. Also, the contents of all working locations are written into an extended trap save area which enables the operating system to make its own independent decision as to whether the system's integrity has been jeopardized. <IMAGE>
Patent EP-0486973-A3 (EP)
Title: Traveler security and luggage control system
IPC: G07B15/00
Filed: 1991-11-15
Abstract: A bar code is used to identify a traveler's luggage, permitting the luggage to be tracked and, if desired, to be delivered to the traveler's ultimate destination (e.g., a hotel). If the traveler is traveling on an airline, a corresponding bar code is applied to the traveler's boarding pass. A bar code reader is used to read the boarding-pass bar code of each emplaning passenger; comparison of these bar codes with luggage bar-code data permits an alarm to be raised if each item of checked luggage is not matched by an emplaned passenger. The boarding-pass bar code may take the form of an integrated passenger identification code for use by, e.g., rental car companies, hotels, and the like.

Title: Improvements in a process for delignifying lignocellulosic pulp by means of oxygen
IPC: D21C9/147
Filed: 1992-06-12
Abstract: The present invention refers to an 
improvement for delignifying a lignocellulosic pulp 
by means of oxygen wherein ethanol is used as an 
additive and the process is carried out at high 
temperature thereby obtaining a higher reduction of 
lignin content of the lignocellulosic pulp, that is, 
a higher reduction of the Kappa Number in comparison 
with conventional processes without, however, 
prejudicing the pulp quality. The use of the present 
invention provides a pulp which, when subjected to 
subsequent bleaching sequences, will require a lower 
amount of chloro compounds in order to achieve the 
desired whiteness and will also exhibit a high 
viscosity thus rendering a product with good 
resistance properties.

IPC: G08G1/0969
Filed: 1996-06-05
Abstract: A current position calculation system is provided for
preventing accuracy in map matching from being degraded due to
errors in an angular difference between road and vehicle
directions. According to a previously determined vehicle current
position and a relative displacement obtained on the basis of the
vehicle direction and travelled distance, the vehicle current
position is estimated as a virtual current position. A most
probable latest current position on a road is determined on the
basis of distances from the virtual current position to line
segments representing part of roads, respectively, and an angular
difference between each of the line segment directions and the
vehicle direction. In addition, there are held a plurality of
angular differences between road and vehicle directions which
are differences between the vehicle directions of predetermined
plural number of previously obtained positions, and the line
segment directions at each of the previously obtained positions
respectively. An averaged value of the plural number of angular
differences between road and vehicle directions is obtained. A
latest vehicle direction detected by a direction detecting means
is modified on the basis of the averaged value. The map matching
process is performed according to this modified vehicle direction.

Abstract: A computer apparatus (20) and method for merging a
sequential plurality of delta streams (30, 32, 34), wherein
each delta stream (30, 32, 34) represents a change to
either a prior delta stream (32, 34), an original data
stream (36), or an updated data stream (52). The method
and apparatus (20) may be used to 1) merge a sequential
plurality of delta streams (30, 32, 34) with an original
data stream (36) to create an updated data stream (52), 2)
merge a sequential plurality of delta streams (30, 32, 34)
to create a compiled delta stream (294), or 3) merge a
sequential plurality of negative delta streams (54, 56, 58)
to retrieve a desired prior data stream (284). The method
and apparatus (20) may be used in conjunction with a
computer backup process, version manager, or the like. In
summary, a consumer process (22) initiates a number of
search requests(102), within a transaction chain (38)
corresponding to the sequential plurality of delta streams
(30, 32, 34), for a number of data bytes to transfer to an
updated data stream (52). The search requests (102) may be
fulfilled (110) with data bytes provided by the last delta
stream in the transaction chain (38) capable of supplying
data bytes, or if the sequential plurality of delta streams
(30, 32, 34) is incapable of fulfilling (110) the search
request (102), it may be fulfilled (112) with data bytes
provided by the original data stream (36). As the
sequential plurality of delta streams (30, 32, 34) is
merged, a sequential plurality of negative delta streams
(54, 56, 58) may be generated, thus enabling reconstruction 
of a desired prior data stream (284).
