Title: Electrophoretic display particles and a process for their preparation
IPC: G02F1/167
Filed: 1987-03-17
Abstract: A process for producing particles for use in electro­phoretic displays, wherein a heavy, solid pigment preferred for its high contrast or refractive index properties is coated with a polymer starting material.

IPC: G03G5/06
Filed: 1987-06-19
Abstract: Multi-active photoconductive insulating 
elements which are sensitive in the far red region 
of the spectrum are comprised of a charge-generation 
layer and a charge-transport layer in electrical 
contact therewith and contain, as the charge-­
generating agent within the charge-generation layer, 
the compound N,N′-bis[2-(3-methylphenyl)ethyl]­
perylene-3,4:9,10-bis(dicarboximide). The charge-­
generation layer is capable, upon exposure to 
activating radiation, of highly effective generation 
and injection of charge carriers and the charge-­
transport layer, which is comprised of an organic 
composition containing an organic photoconductive 
material, is capable of accepting and transporting 
the injected charge carriers to thereby form a 
highly advantageous multi-active photoconductive 
insulating element.

Patent EP-0273466-A3 (EP)
IPC: B64C5/00
Filed: 1987-10-23
Abstract: Airplanes which feature composite construction 
and have: a further aft than conventional center of 
gravity; a clean wing with a high aspect ratio; and all 
primary flight controls. These include trailing edge 
control segments (or members or elements) which extend 
the full span of the airplane wing. A central processor 
so schedules the upward and downward deployment of the 
control elements that: (1) downward and upward 
displacements of the control elements are respectively 
accompanied by pitch-up and pitch-down moments; (2) the 
inboard control elements are used primarily to change 
the coefficient of lift whereas roll control is effected 
principally by displacement of the outboard control 
elements; and (3) each of the control elements is 
individually displaced by a system which eliminates 
hydraulic systems a nd control cables. Hallmarks of 
these novel airplanes include simplicity, relatively low 
cost, lower weight, and safety.

Title: Parallel optical arithmetic/logic unit
IPC: G02F3/00
Filed: 1988-02-26
Abstract: A parallel optical arithmetic/logic unit has inputs from 
point-light sources (20-23) forming a given spatial pattern 
corresponding to a given separation of point sources. The spa­
tial pattern is presented to a multiplicity of channels by an 
optical system formed of linear optical elements (30-32, 
40-42, 50-52). A static filter (40-42) is provided in each 
channel which allows energy to pass when it comes from one 
spatial pattern but attenuates or diverts energy from all 
other spatial patterns. Thus energy will emerge predominantly 
from only one channel from each specific spatial pattern sepa­
rated by a given separation of point sources. The desired out­
put state of each channel may be detected to indicate the re­
sults of an optical arithmetic or logic operation.

Title: Routing method for fast packet switching systems
IPC: H04L12/56
Filed: 1989-05-23
Abstract: A fast packet switching system comprises an interconnection 
network associated with a distributed control structure composed of a 
plurality of processing units (UC1-1 ... UC3-16) managing the routing 
at the virtual call level. At least some of said processing units 
associated each with a group of network inputs/outputs store bandwidth 
occupancy data relevant to the interstage links which can be reached 
from the inputs of said group and are included between said inputs and 
a central network stage where there is a maximum number of alternative 
paths or, respectively, bandwidth occupancy data relevant to 
interstage links which lead to the outputs of said group and are 
included between said stage and the output, said data being updated 
whenever a new call is routed.  
     When a virtual call is to be routed, the processing units 
associated with the input or respectively the output involved in the 
connection, evaluate each, on the basis of the up-to-date conditions 
of bandwidth occupancy and of the bandwidth requirements of the new 
call, a cost function of the connection along the portion of each of 
the possible routing paths included between the input and the stage 
where there is the maximum number of alternative paths, or 
respectively for the portion of each routing path included between 
such stage and the output; the results of the evaluations carried out 
by said units are combined together in one of the units which 
determined a global cost function for the individual connection paths 
and forwards the call on the path presenting the minimum cost 
function.
