Title: Self-calibrating variable pressure touch key system employing transducers subject to parameter drift
IPC: H01H13/00
Filed: 1992-09-29
Abstract: A pressure sensitive touch pad system, for example 
employing variable capacitance touch pads, employs low cost 
transducers subject to parameter drift and periodically (e.g. 
once each second) re-calibrates each touch pad. The periodic 
re-calibration allows a low cost transducer to be used for 
multi-point operation, as well as for simple on/off operation, 
such as for function selection. One application is to provide 
different slew rates for setting a data entry indicator, for 
example indicating the value of an appliance function.
Patent EP-0568937-A3 (EP)
IPC: B66B1/20
Filed: 1993-04-30
Abstract: The invention relates to a procedure for 
controlling an elevator group consisting of 
several elevators and related call devices. 
A control system for controlling the elevators 
controls each elevator in a manner determined 
by the calls entered and the existing 
control instructions. According to the 
invention, when the control system has to 
decide between two or more control alternatives, 
a systematic decision analysis is 
performed by studying the effects resulting 
from each alternative decision, said effects 
being estimated by simulating by a Monte-Carlo 
type method the future behaviour of 
the elevator system in the case of each alternative 
decision. To carry out the simulation, 
realizations are generated at random 
for the unknown quantities associated with 
the current state of the elevator system and 
for new external future events, and a control 
decision is made on the basis of the 
results of the decision analysis.

Inventor: SMITH CRAIG M
IPC: G06T5/00
Filed: 1995-12-18
Abstract: Improved processes for quantizing a set of
mean-preserving Tone Transfer Functions (TTFs) for a
multi-level halftoning system which minimize or at
least significantly reduce the overall quantization
error in the system as a function of a prespecified
system halftone cell size, P, and the number of micro
output levels, L y , supported by the multi-level
halftoning system. The processes call for dividing the
range of possible input contone representative
intensity values into T subintervals, where  T=PL y   ;
determining the values of the centers of the T-subintervals;
and quantizing each of the normalized
continuous mean preserving TTFs as a function of the
values of the centers of the T-subintervals. According
to a preferred embodiment, the quantizing is performed
such that the quantized TTFs approximate the normalized
continuous mean preserving TTFs and ideally satisfy the
criteria that the maximum quantization error between
any quantized and unquantized TTF is minimized.
Further aspects of the invention are directed to
methods for determining threshold levels for assignment
to threshold matrices, and methods for specifying look-up
tables, either of which (the matrices and look-up
tables) may be used for converting input contone
representative intensity values into a predetermined
number of available micro output levels for a
multilevel halftone system having a predetermined
halftone cell size.

Abstract: In processing a digital information signal (a digital video
signal etc), an improvement in the accuracy of the signal process can
be made by integrating the time region process and the frequency region
process. In one embodiment, an input digital video signal is supplied
to a DCT circuit 3. The DCT circuit 3 converts the input video digital
signal into coefficient data. A categorizing circuit 5 separates a
flat component 6a and an impulse component 6b in a frequency region
from the input signal. The flat component 6a is supplied to an inverse
DCT circuit 7. The inverse DCT circuit 7 converts the input signal
into a signal on a time axis. A class categorizing adaptive processing
circuit 9 compensates a resolution in a time region. The impulse
component 6a is supplied to a gain converting circuit 10. The gain
converting circuit 10 compensates the high band in a frequency region.
The output signal of the gain converting circuit 10 is supplied to an
inverse DCT circuit 11. The inverse DCT circuit 11 converts the input
signal into a signal on a time axis. A mix circuit 14 mixes signals
that have been processed. Thus. a video signal compensated the
resolution is obtained from an output terminal 15. The adaptive
procession circuit 9 and the gain converting circuit 10 use pre-learnt
predicted coefficients, predicted values, and gain converting ratio.

Abstract: Several techniques may be used for forming a colored 
interference filter coating on a substrate (10) such as 
polyester film. The interference filter has two metal 
reflective films (11,13), at least one of which is 
semi-transparent. A layer of transparent acrylate polymer 
dielectric (12) between the metal layers (11,13) completes the 
interference filter, which may be sandwiched between 
protective layers. The dielectric (12) is formed by 
evaporating an acrylate monomer having a molecular weight 
in the range of from 150 to 600. Preferably the acrylate 
monomer has a molecular weight to acrylate group ratio in 
the range of from 150 to 400. The acrylate condenses on 
the substrate and is polymerized in situ for forming a 
monolithic film with a sufficient thickness to produce an 
interference color. In several embodiments different 
areas of the film have different thicknesses for producing 
different interference colors. The thickness of the 
dielectric can be controlled by the amount of monomer 
condensed, by either controlling the temperature of the 
condensation surface or controlling the amount of monomer 
evaporated adjacent a predetermined area of the substrate. 
Thickness may also be controlled by condensing a uniform 
layer of monomer and polymerizing the monomer to different 
degrees for varying the shrinkage of the film and hence 
the thickness of the film and color.

Abstract: A color reflective guest-host liquid-crystal display
device is provided which does not require a polarizing
plate and which has a bright screen. A transparent
electrode is formed on an upper substrate of a color
reflective guest-host liquid-crystal display device. A
reflection electrode is formed on a lower substrate, and
an electro-optic element is held in the spacing between
the two substrates so as to perform light modulation in
response to an applied voltage. The electro-optic element
has a laminated structure including a guest-host liquid-crystal
layer which contains a dichroic dye and which is
uniformly oriented along the transparent electrode, and a
phase shifter which has a predetermined optical
anisotropic axis and, which is formed along the reflection
electrode. The transparent electrode and the reflection
electrode face each other and define a plurality of
pixels. A color filter assigns incident light of a
different wavelength to each pixel. The phase shifter is
divided for each pixel, and the thickness thereof is
adjusted according to a corresponding wavelength.
Further, when this liquid-crystal display device is formed
into an active matrix type, the pixel aperture ratio can
be improved by providing the color filter on the drive 
substrate side on which switching elements and pixel
electrodes are formed rather than on the facing substrate.
