Utilizing time-of-flight radars operating in Ku-, K-, and Ka-bands (12-18 GHz, 18-27 GHz, and 26.5-40 GHz) to track objects within defined areas, generating data for processors to determine events and trigger actions based on predefined criteria.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If video cameras or proximity sensors are used for tracking, then tracking capability is provided, but coverage gaps and accuracy issues occur

Engineering Contradiction:

Improvetracking accuracyVSAvoidcoverage continuity

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The patent replaces mechanical/optical tracking systems (video cameras, proximity sensors) with electromagnetic radiation-based radar systems. The radar transmits electromagnetic waves that reflect off objects to provide continuous tracking data, eliminating the coverage gaps and accuracy limitations of conventional mechanical sensing methods.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent utilizes different radar frequency bands (Ku-band: 12-18 GHz, K-band: 18-27 GHz, Ka-band: 26.5-40 GHz) to optimize tracking performance. By selecting appropriate frequency parameters, the system achieves both high accuracy and continuous coverage, resolving the contradiction between measurement precision and reliability.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If tracking technology is implemented, then safety monitoring is improved, but privacy concerns arise

Engineering Contradiction:

Improvesafety monitoringVSAvoidprivacy intrusion

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts only the essential tracking information (position, movement, presence) from the electromagnetic radiation interactions, eliminating the need for visual imaging or detailed observation that would compromise privacy. The radar provides safety monitoring by detecting motion and location without capturing images or detailed sensory data about the tracked individual.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Electromagnetic radiation serves as an intermediary that enables safety monitoring without direct observation. The radar waves interact with objects indirectly through reflection, allowing the system to detect presence and movement without penetrating privacy boundaries or capturing identifiable visual information.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Measurement precision

If radar systems are used for tracking, then tracking accuracy is improved, but radiation regulation compliance becomes complex

Engineering Contradiction:

Improvetracking accuracyVSAvoidregulation compliance

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent employs radar systems with controlled electromagnetic radiation at levels that are sufficient for accurate tracking but remain within regulatory limits. By using appropriate power levels and frequency bands (Ku, K, Ka bands), the system achieves the necessary tracking accuracy without excessive radiation that would complicate compliance with safety regulations.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

This disclosure enables various technologies for tracking various objects (e.g., mammals, animals, humans, pets) within various defined areas (e.g., rooms, apartments, residences, vehicles, tents) to determine whether those objects satisfy or do not satisfy various criteria, signatures, or thresholds, which may relate to health, safety, or security of those objects within those defined areas. These technologies may be enabled via various radars (e.g., time-of-flight radars, Doppler radars) positioned within those defined areas to track those objects therein. For example, some of such radars may operate in a Ku-band inclusively between about 12 GHz and about 18 GHz, a K-band inclusively between about 18 GHz and about 27 GHz, or a Ka-band inclusively between about 26.5 GHz and about 40 GHz, each of which has been unexpectedly found to be technologically beneficial for tracking those objects within those defined areas.
