Title: Analog-to-digital converter
IPC: H03M1/36
Filed: 1989-09-14
Abstract: Apparatus for of digitizing an input analog current signal such as 
a demodulated servo position error signal in a disk file includes a 
capacitor which is changed by with the input signal, and a plurality of 
comparators which compare the resulting capacitor voltage with a 
plurality of thresholds to produce a comparator output signal for each 
threshold exceeded by the capacitor voltage. The comparator output 
signals are sampled, and each sampling period a current corresponding to 
the thresholds exceeded is generated. The generated current is used to 
draw off charge from the capacitor until an equilibrium voltage is 
reached. By knowing the current generated to remove from the capacitor 
the voltage placed thereon by the input current signal, then the total 
charge applied to the capacitor can be determined. Further digital 
processing of the input signal value may be done without the use of a 
complicated digital to analog converter.

Title: Method and system for enhancing the quality of both color and black and white images produced by ink jet printers
IPC: B41J2/21
Filed: 1989-11-30
Abstract: A method for reducing "grainyness" or color contrast 
in color imaging systems and simultaneously reducing or 
eliminating paper cockleing of media printed by ink jet 
printing. The method involves determining the maximum 
allowable ink print density necessary to reduce or eliminate 
paper cockleing in the printed media and then providing tight 
control of the selection of gray scale ink drop count and 
associated dye loading in relation to this maximum allowable 
print density. Using this method, pixels are selected and 
printed in such a manner as to maximize the uniformity of ink 
distribution on the printed media.  
     This method will work using either a variable drop 
size or a fixed drop size with variable dye loadings. It will 
also work with most error diffusion or dithering schemes 
presently used and available in the image processing arts.

Title: Method of etching polyimides and resulting passivation structures
IPC: H05K3/00
Filed: 1990-02-23
Abstract: A method of etching polyimide material having metal­
lization patterned thereon in which an epoxy resin 
system not only provides the etch mask for etching the 
polyimide but also provides a resulting passivation 
structure overlying the metallization on the polyimide 
substrate. The polyimide having a desired metalliza­
tion pattern thereon is coated with the epoxy based 
photoimageable material which has the properties of 
resisting concentrated KOH etching when the epoxy 
material is cured and also the property of adhering to 
the polyimide substrate and the metallized pattern 
after exposure to the KOH etch to provide a pas­
sivation to the metallization. The process includes 
exposing the layer of photoimageable material to 
actinic radiation to selectively pattern the material, 
developing the patterned material to reveal the 
underlying polyimide to be etched, curing the re­
maining material and etching the revealed polyimide 
material in concentrated KOH to remove the revealed 
polyimide. The remaining epoxy material is firmly 
adherent as a passivation layer for the metallization. 
Preferably the epoxy material consists essentially of 
from about 10% to about 80% by weight of a polyol 
resin which is a condensation product of epichloro­
hydrin and bisphenol A having a molecular weight of 
between about 40,000 to 130,000, and between about 20% 
and 90% by weight of an epoxidized octafunctional 
bisphenol A formaldehyde novolak resin, having a 
molecular weight of between 4,000 to 10,000 and about 
 
 
0.1 to about 15 parts by weight of resin of a cationic 
photoinitiator capable of initiating polymerization of 
the epoxidized resin system upon exposure to actinic 
radiation. The resin may optionally contain up to 
about 50% by weight of epoxidized di-glycidal ether of 
tetrabromo bisphenol A having a molecular weight of 
between about 600 and 2,500, if flame retardancy is 
required.

The output terminals of successive switching elements of a matrix output line are in each case connected in reversed manner to their signal conductors.
Patent EP-0393767-A3 (EP)
Title: Method and apparatus for forming preformed material
IPC: B29C33/68
Filed: 1990-04-12
Abstract: A method and apparatus are disclosed for the shaping of a 
sheet of preform material. A flat planar (heated) sheet of preform 
material is held tightly between two elastomeric sheets, the sheets 
and preform material forming a laminate assembly. The laminate 
assembly is then formed about a mold having the desired contours. 
The elastomeric sheets maintain the preform material parallel to 
the surface contours of the mold as the molding process proceeds. 
A fluid such as air is flowed between the mold surface and the 
laminate assembly during the forming process to prevent the 
elastomeric sheets from binding on the mold surface. Wrinkles are 
eliminated in the final shape of the preform material, and fiber 
distortion or tears or rips in the material are minimized due to 
the fluid lubrication between the mold surface and the laminate 
assembly.

Patent EP-0394041-A3 (EP)
IPC: G01N11/04
Filed: 1990-04-19
Abstract: An instrument for performing assays is taught 
including one or more of the following features: an 
APTT test is performed utilizing a bandpass filter 
centered at approximately 45Hz in order to provide the 
best analysis of scattered light for properly detecting 
the endpoint of the APTT assay; a floating theshold 
voltage is used for comparison with the output signal, 
thereby avoiding problems which cause false endpoint 
detection; periodic determinations are made to ensure 
that an adequate supply of sample is present in the 
sample well, thereby avoiding false indications of an 
adequate supply of sample due to sample drying; pulses 
of light are used rather than modulated light, thereby 
obviating the need for a modulator while providing 
scattered light from a sample which can be easily 
distinguished from ambient light; unique codes 
contained on a quality check device are utilized for 
customization, for example, to establish the language 
in which the prompts will be presented to the user, or 
the units of measurement which will be displayed; and a 
thermal code is used to control the temperature of the 
cartridge containing the sample and one or more 
reagents within very close tolerances.

composite layer associated with an individual pixel of a 
particular pixel group is operable to emit light energy at 
the light-emitting face of the individual pixel when a 
first electrical signal is applied to the first electri­
cally conductive layer which is common to the pixel group 
simultaneously with the application of a second electrical 
signal to the individual pixel second electrically 
conductive element.

Title: Value-added service for a communication system with wired and/or wireless channels
IPC: H04W88/18
Filed: 1991-02-14
Abstract: 2.1 With value-added services, not only can the use of a data transmission system be made more attractive for the subscriber, but traffic quality can in most cases also be improved. Data transmission systems in which the possibility exists for implementing a value-added service are, for example, the car telephone system, the radiopaging system known as City-Ruf, etc. The possibility of setting up value-added services essentially exists for every information provider. One of the most difficult problems which the value-added service operator has to solve is the control of access authorisation for the value-added service subscribers and charge calculation. 2.2 With the new value-added service, a high degree of protection against abuse is afforded for both the value-added service operator and the value-added service subscriber, in that the reception authorisation is dependent on an identification code assigned to at least one group of radio receivers and on a key contained in the value-added service messages. This key cannot be displayed and defines the time period for the reception authorisation. 2.3 The new value-added service can be used in differently configured data networks for switched connections. <IMAGE>

Title: Method for treating waste dump material, more particularly old waste dumps
IPC: B09C1/00
Filed: 1991-08-21
Abstract: The invention relates to a process, by means of which waste material in landfills, preferably from old dumps in domestic refuse landfill sites which are no longer active, or from old dump areas of sites still operating, can be reprocessed in order to reduce the original extent of the landfill site at a later stage and hence to recover useful areas. After coarse materials have been sorted out, the material taken from the landfill is subjected to float fractionation in water basins, in which biodecomposition with production of a biomass also takes place. Combustible floating materials, excess biomass, combustible coarse materials and biogas obtained from biomass are burned to release useful energy. Ash and incombustible material, which is comminuted if necessary, require substantially smaller landfill areas for dumping.
