Solution Overview

Problem

Current sensor systems face challenges in efficiently encoding and classifying high-dimensional sensor data from distributed sensor nodes, particularly in noisy environments and with high-dimensional vector transmission, where existing methods often require complex encoding and decoding processes and are not scalable.

VSEngineering Contradiction Analysis

1Device complexity

If sensor data is transmitted using traditional encoding methods, then the transmission process is well-established, but the system requires complex encoding and decoding processes that increase device complexity and processing time

Engineering Contradiction:
Improveencoding and decoding processesVSAvoidprocessing time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent extracts and removes the complex encoding and decoding processes from the transmission system. By using high-dimensional vectors with inherent error-tolerance properties, the system eliminates the need for separate channel encoding and decoding stages, directly reducing device complexity and processing time while maintaining transmission reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transforms sensor data into high-dimensional vector space, transitioning from traditional low-dimensional representations to thousands of dimensions. This dimensional expansion provides inherent redundancy and error-tolerance, allowing the system to achieve reliable classification without complex encoding/decoding processes.

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

2Reliability

If the sensor system uses high-dimensional vectors for data transmission, then error tolerance is improved, but the device complexity increases due to high-dimensional computing requirements

Engineering Contradiction:
Improveerror toleranceVSAvoidhigh-dimensional computing
Core Design Contradiction:

Solution Approach 1:

The patent merges the error-tolerance mechanism directly into the data representation itself. High-dimensional vectors inherently possess error-tolerance properties through their distributed representation across thousands of dimensions, eliminating the need for separate error-correcting code structures and reducing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The high-dimensional vectors are self-sufficient in providing error tolerance without requiring external encoding or decoding assistance. The vectors' inherent mathematical properties automatically provide robustness against noise and interference, making the system self-correcting and reducing computational overhead.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If more sensor nodes are added to the distributed system, then sensing coverage is improved, but the classification accuracy deteriorates due to increased noise accumulation

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent converts the harmful effect of noise accumulation into a beneficial feature. By using high-dimensional vectors, the system transforms the addition of multiple noisy sensor readings into a constructive process where the high-dimensional space naturally filters and integrates the signals, improving classification accuracy even as more nodes are added.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent uses dimensionality expansion to resolve the trade-off between sensing coverage and accuracy. By projecting sensor data into high-dimensional space, the system can accommodate more sensor nodes without losing discrimination capability, as the increased dimensions provide sufficient separation between different signal patterns even in the presence of noise.

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

Solution Approach 1:

The patent removes traditional channel encoding and decoding operations from the transmission pipeline. High-dimensional vectors inherently provide error protection through their distributed representation, eliminating the need for separate protective encoding layers and their associated processing complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The error protection capability is built into the data representation before transmission occurs. By encoding information into high-dimensional vectors with inherent robustness properties, the system prepares the data to be naturally resistant to errors, eliminating the need for subsequent decoding and error-correction operations.

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention is notably directed to a sensor system for performing distributed sensing and classification of sensor data. The sensor system comprises a set of distributed sensor nodes for sensing the sensor data. The sensor system is configured to encode the sensor data of each sensor node of a set of distributed sensor nodes for sensing the sensor data as high-dimensional vectors and to transmit the high-dimensional vectors over a respective link between the respective sensor node and a receiver system. The sensor system is further configured to superpose the high-dimensional vectors of the sensor data from the set of sensor nodes by physical superposition, thereby generating a superposed high-dimensional vector and to classify the superposed high-dimensional vectors at the receiver system.
