Solution Overview

Problem

Electrical test and measurement environments face challenges in displaying complex signals and device under test (DUT) waveforms intuitively, leading to increased complexity and time consumption in tasks such as signal acquisition and probe placement, with risks of damaging DUTs from incorrect ground connections.

Innovation Solution

An augmented reality system is integrated with test and measurement equipment, allowing virtual and augmented content to be overlaid on the physical environment, providing immersive visualization, guidance for probe placement, and real-time feedback on acceptable ground connections, enabling users to interact with signals and data in three-dimensional space using gestures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional display methods are used for complex signals, then the test and measurement equipment can display waveforms, but the display is not intuitive and task complexity increases

Engineering Contradiction:
Improveintuitiveness of waveform displayVSAvoidcomplexity of test tasks
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent overlays virtual waveform displays and measurement data onto the physical DUT in three-dimensional space, transforming traditional two-dimensional display into a spatial augmented reality interface. This allows users to see waveforms and measurements directly at the location of the physical device, making the display more intuitive and reducing task complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces an augmented reality system as an intermediary between the test and measurement equipment and the user. This intermediary overlays virtual information (waveforms, measurements, guidance) onto the physical environment, bridging the gap between complex equipment data and user comprehension.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If users manually locate probing points on complex DUTs, then signal acquisition can be performed, but the process becomes increasingly difficult and time-consuming

Engineering Contradiction:
Improvesignal acquisition efficiencyVSAvoidtime to locate probing points
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent pre-identifies and marks probing points on the DUT schematic diagram before the user begins physical testing. The augmented reality system overlays these pre-identified locations onto the physical DUT, guiding users directly to the correct probing points and eliminating the need to manually search through complex device layouts.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent creates a virtual copy of the DUT schematic diagram and overlays it onto the physical device. This virtual replica includes marked probing points and signal paths, allowing users to reference the schematic location directly on the physical device without manual interpretation or translation between documents and hardware.

Inventive Principle:
Principle #26Copying

3Reliability

If users apply probes to DUTs without guidance, then measurements can be taken, but there is risk of damaging the DUT from incorrect connections

Engineering Contradiction:
Improvesafety of DUT operationVSAvoiddifficulty of determining acceptable contact locations
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent provides real-time feedback through the augmented reality display, showing users whether their probe placement is correct or incorrect. The system overlays visual indicators that confirm acceptable contact locations and warn against harmful connections, allowing users to immediately adjust their actions based on system feedback.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent pre-identifies and marks unacceptable locations for probe connections on the DUT before the user makes any connections. The augmented reality system displays warning indicators at these locations, preventing users from making harmful connections in the first place by showing them exactly where not to connect.

Inventive Principle:
Principle #9Preliminary anti-action

AI summary

A test and measurement system can include a data store configured to store augmentation settings for dynamically augmenting a physical testing environment and a computing device coupled to the data store. The computing device can be configured to receive an input feed from the physical testing environment, create an augmentation image based on the augmentation settings and the input feed, and output the augmented image to be overlaid on the physical testing environment to augment a user's view of the physical testing environment.
