Problem
Existing systems for detecting human actions and movements using millimeter wave radar technology face challenges due to high power dissipation, making it difficult to effectively implement and analyze signal data in networked systems, particularly in areas where devices are installed for monitoring purposes.
Innovation Solution
A system comprising millimeter wave radar detectors connected to an Access Point (AP) in a mesh network, where the AP receives and analyzes signal data to determine movements or actions, and generates feedback responses, utilizing a computing device to control external devices for providing visual or audio feedback, while also managing power supply and data communication through USB or Power over Ethernet connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radar and image processing systems are used to detect and identify physical actions or movements, then detection capability is improved, but power consumption increases significantly
Solution Approach 1:
The patent introduces an access point as an intermediary device that receives raw signal data from low-power radar detectors and performs the computationally intensive signal processing and image generation functions. This mediator approach allows the radar detector itself to consume minimal power while still achieving high detection capability through the access point's processing resources.
Solution Approach 2:
The patent extracts the power-intensive signal processing and image processing functions from the radar detector and relocates them to the access point. This separation allows the radar detector to operate with minimal power consumption while the access point handles the computationally demanding tasks of analyzing signal data and generating images of physical actions.
2Measurement precision
If significant power dissipation is provided for radar detection, then detection accuracy is improved, but device installation feasibility deteriorates
Solution Approach 1:
The access point serves as a mediator that provides the computational power needed for high detection accuracy without requiring the radar detector itself to dissipate significant power. This enables easy installation of low-power radar detectors in ceiling or wall locations while maintaining high detection accuracy through the access point's processing capabilities.
Solution Approach 2:
The patent replaces the mechanical/electrical power-intensive radar processing system with a wireless network-based processing system. Instead of providing significant power dissipation at the detector location, the system uses wireless communication to transfer raw data to an access point for processing, making installation much easier while maintaining detection accuracy.
3Loss of time
If signal data is processed in real-time at the detector, then response time is improved, but power consumption increases
Solution Approach 1:
The access point acts as a real-time intermediary that receives continuous streams of raw signal data from the radar detector and processes it immediately. This mediator approach enables real-time response to detected physical actions while the radar detector itself consumes minimal power, as the processing burden is handled by the always-on access point.
