Solution Overview

Problem

Dynamic registration systems face challenges in accurately enrolling new pattern information without incorrect mapping or overuse of previously mapped data, leading to potential false acceptances and reduced matching efficiency.

Innovation Solution

Implementing a multi-match model that requires a minimum and maximum number of independent matches between a pattern-under-test and trusted template elements to dynamically enroll information, balancing confidence in matching while preventing overmapping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If dynamic registration continuously collects pattern information to increase the mapped pattern region, then the coverage of enrolled data improves, but the risk of adding incorrectly matched data increases

Engineering Contradiction:
Improvepattern region mappedVSAvoidcorrectness of enrollment
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The patent applies local quality by evaluating and weighting different regions of the pattern source differently during dynamic enrollment. Instead of treating all matched regions equally, the system assesses the quality and reliability of each local match, allowing high-confidence regions to contribute to enrollment while excluding low-confidence regions. This resolves the contradiction by enabling expanded coverage through selective inclusion of only reliable pattern regions.

Inventive Principle:
Principle #3Local quality

2Productivity

If dynamic registration enrolls new pattern information aggressively to improve matching speed, then the productivity of matching improves, but the accuracy of matching deteriorates

Engineering Contradiction:
Improvematching speedVSAvoidmatching accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent employs parameter changes by dynamically adjusting enrollment thresholds and confidence requirements based on the current state of the trusted template. As the template accumulates more pattern information, the system modifies parameters such as match confidence thresholds and region weighting factors to maintain accuracy. This allows the system to enroll new information efficiently while preserving matching precision through adaptive parameter adjustment.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If dynamic registration repeatedly maps the same pattern region to build confidence, then the confidence level increases, but the system becomes slow due to overuse of previously mapped information

Engineering Contradiction:
Improveconfidence levelVSAvoidmatching speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies preliminary action by pre-assessing the quality and uniqueness of pattern regions before committing them to the trusted template. The system performs preliminary evaluation of candidate regions to determine their potential contribution to enrollment confidence, avoiding redundant mapping of already-sufficient regions. This preliminary filtering mechanism builds confidence efficiently without the slowdown caused by repeatedly processing the same pattern information.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If the system enrolls pattern information from multiple matches to increase confidence, then the reliability of enrollment improves, but the complexity of the enrollment process increases

Engineering Contradiction:
Improveenrollment confidenceVSAvoidenrollment process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the dynamic enrollment process into distinct stages: initial pattern collection, match evaluation, confidence assessment, and selective enrollment. Each stage processes specific aspects of the pattern data independently, managing complexity through modular organization. The multi-match requirement is implemented as a series of discrete evaluation steps rather than a monolithic process, making the system more manageable while maintaining high enrollment reliability.

Inventive Principle:
Principle #1Segmentation

AI summary

A system and method for selectively enrolling new pattern information in a way that reduces incorrect mapping or reduces overuse of previously mapped pattern information using a multi-match model. A method for dynamically enrolling a pattern-under-test into a pattern template, the pattern template including a set of template elements, may include a) determining a number N of template elements of the set of template elements matched by the pattern-under-test, wherein N is greater than one; b) establishing a multi-match mode for a dynamic enrollment of the pattern-under-test into the pattern template; and c) enrolling dynamically the pattern-under-test responsive to the multi-match mode.
