Patent EP-0299301-A3 (EP)
IPC: G06Q40/02
Filed: 1988-07-01
Abstract: A method is disclosed for computer 
implementation of products wherein a designer 
examines the products desired by an institution 
planner and identifies functions ("components") 
collectively common thereto. The designer proceeds 
to define component processes collectively common to 
such component and categorizes code for this 
purpose in groupings selectable (executable) by the 
planner upon system installation and subsequently 
changeable as desired. The component process 
selections of the planner are recorded and the 
system is thereby defined in its aspect which is 
accessible to the planner. The designer works from 
such definitions of all components and component 
processes obtained from discussion with system 
planners prior to installations to define component 
subprocesses collectively common to the component 
processes and identifies combinations of component 
subprocesses in various sequences to realize 
component processes. The code of each component 
subprocess is stored individually in "modules" for 
access by a computer to realize such combinations 
and reuse of such modules in this activity is 
effective to provide for uniformity in the practice 
of subcomponent processes from product to product. 
The designer code for the component subprocess is 
inaccessible to the planner from a selection 
viewpoint and is viewed thusly as planner 
non-executable.

Filed: 1989-04-21
Abstract: In a fingerprint processing system for use in 
detecting a core position of a fingerprint image 
quantized into a plurality of picture elements, 
statistical processing is carried out in relation to 
parameters which are variable in dependency upon the 
core position and directions and curvatures of the 
picture elements preliminarily detected to specify 
ridges of the fingerprint image. The parameters may be 
existence probabilities of the core position that are 
determined for the directions and the curvatures. Such 
existence probabilities are successively calculated at 
each picture element and adjacent picture elements to be 
summed up and to detect a maximum one of the existence 
probabilities. A position which has the maximum 
existence probability is judged as the core position. 
Alternatively, the parameters may be differences between 
practical curvatures extracted from the fingerprint 
image and reference curvatures defining a reference 
curve. A minimum one of the differences is 
statistically detected with reference to various kinds 
of the reference curves. In addition, the directions 
and the curvatures of the picture elements may be 
determined by deriving the density levels of the picture 
elements along a plurality of arcuate lines specified by 
line directions and line curvatures.

Title: Identifying gemstones
IPC: B07C5/342
Filed: 1989-05-08
Abstract: In order to determine whether a particle is a diamond, 
514.5 nm laser radiation, modulated at a frequency of 10 
MHz to 1 GHz, is projected onto the particle 2, and the 
radiation emitted by the particle 2 is collected by a 
wide aperture viewing system 23 with narrow band pass 
filtering of the diamond Stokes or anti-Stokes Raman 
frequency appropriate to the laser wavelength. The 
emitted radiation is detected by a detector 6, and an 
associated electronic circuit 13,14,15 detects signals 
modulated at the same frequency as the laser modulation 
frequency. In this way, only Raman radiation is 
detected as this has a very short rise/decay time; other 
luminescence forms a background which is not modulated 
and can be removed by for instance thresholding, or 
heterodyne techniques. The method can be used to sort 
diamond from gangue on a wide belt, without very 
complicated optics.

Title: Electric energy metering
IPC: G01R11/00
Filed: 1989-09-15
Abstract: Redundant pulses generated by independently operable 
pulse sources in an electricity meter are accumulated as 
pulse counts in a pair of channels of a multi-channel 
recorder. The pulse counts are compared to verify the 
accuracy of the pulses counted by each channel. If the 
difference between the values of the pulse counts exceeds 
a predetermined threshold value, a trouble indicator is 
turned on and a telephone call is initiated by the 
recorder to notify a data center that a system 
malfunction has occurred which is disrupting the 
accumulation of pulses in one of the channels of the 
recorder. The pulse counts are stored in the recorder as 
substantially duplicate independent measures of energy 
usage by a load connected to the electricity meter, to be 
thereafter retrieved from the recorder to obtain energy 
survey and billing data. The recorder also maintains a 
system status error log which records the time and date 
of each malfunction and the identification of the channel 
pair where the malfunction occurred. In one embodiment, 
the operation of the recorder is controlled by a 
programmable microprocessor. Combinations of independent 
power sources for powering the recorder and the pulse 
sources are employed to enhance system reliability by 
making each of the pulse sources and the recorder 
substantially independently operable.
