Solution Overview

Problem

Scientific experiments face challenges in synchronizing and analyzing multimodal signals due to gaps in data, tracking method jumps, and lack of relation between tracking methods, leading to complex data tangles and difficulty in determining relationships.

Innovation Solution

Implementing a system with a universal clock to synchronize and track inputs and outputs of scientific instruments, using a common clock to timestamp and analyze signals, thereby eliminating the need for XY position-based tracking and reducing the impact of environmental disturbances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple tracking methods are used for different signal types, then each signal can be tracked independently, but data correlation becomes difficult and relationships cannot be determined

Engineering Contradiction:
Improvesignal tracking capabilityVSAvoiddata correlation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by implementing a single universal clock that serves all signal types (STEM, EELS, X-ray, optical, acoustic) instead of separate tracking methods. This universal time reference enables consistent timestamping across diverse modalities, resolving the data correlation problem while maintaining adaptability to different signal types.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If XY position-based tracking is used, then signal acquisition can be recorded, but environmental disturbances cause tracking method jumps and data gaps

Engineering Contradiction:
Improvesignal acquisition stabilityVSAvoidenvironmental disturbance impact
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a universal clock as an intermediary time reference that decouples signal tracking from physical position tracking. This mediator provides a stable temporal framework that is immune to environmental disturbances affecting XY position, thereby eliminating tracking jumps and data gaps caused by vibrations and drift.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical XY position-based tracking system with a temporal time-stamping system based on a universal clock. This substitution eliminates the susceptibility to mechanical environmental disturbances (vibrations, drift) that affect position-based tracking, providing stable and continuous signal acquisition.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If separate timelines are used for different signal types, then each signal can be acquired independently, but aggregated data resembles a complex tangle that is difficult to analyze

Engineering Contradiction:
Improvesignal acquisition efficiencyVSAvoiddata relationship analysis
Core Design Contradiction:
ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent merges separate signal timelines into a unified temporal framework by timestamping all signals (STEM, EELS, X-ray, optical, acoustic) with references to a single universal clock. This combining of previously separate tracking methods into one common time reference enables straightforward correlation and analysis of multimodal data without the complexity of multiple independent timelines.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Embodiments described herein relate to a process for multimodal signal acquisition, such as from a charged particle device or other scientific instrument, based on universal clock synchronization of the various multimodal signals. A system can comprise a memory that stores computer executable components; and a processor that executes the computer executable components stored in the memory, wherein the computer executable components comprise an identifying component that identifies a set of inputs and outputs of a scientific instrument, and a parameterizing component that tracks the inputs and outputs of the set based on a universal clock common to the inputs and outputs of the set.
