PRESENCE DETECTION USING UWB RADAR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240310504 titled 'PRESENCE DETECTION USING UWB RADAR
The abstract describes a method for presence detection using ultra-wide band (UWB) radar, which involves obtaining centroids based on UWB radar measurements and classifying them as human or non-human movement.
- The method classifies centroids based on features satisfying a human movement condition.
- When a centroid is classified as human movement, the method determines a 2D location of human movement.
- The current state value indicating human presence in a 3D space is updated based on centroid classification.
Potential Applications: - Security systems for detecting human presence in restricted areas. - Monitoring systems for tracking human movement in indoor environments. - Smart home applications for presence detection and automation.
Problems Solved: - Efficient and accurate human presence detection using UWB radar technology. - Real-time tracking of human movement within a defined space. - Enhancing security measures by detecting unauthorized human presence.
Benefits: - Improved security and surveillance capabilities. - Enhanced automation and control in smart home environments. - Increased efficiency in monitoring human activity in various settings.
Commercial Applications: Title: "Advanced Presence Detection System for Security and Automation" This technology can be utilized in security systems for commercial buildings, smart home devices, and industrial applications to enhance safety and efficiency.
Questions about the technology: 1. How does this method improve upon existing presence detection technologies? - This method offers more accurate and reliable human presence detection using UWB radar, leading to enhanced security and automation capabilities. 2. What are the potential limitations of using UWB radar for presence detection? - UWB radar may face challenges in certain environments with high interference or obstacles that could affect the accuracy of human movement detection.
Original Abstract Submitted
a method for presence detection using ultra-wide band (uwb) radar includes obtaining a set of centroids based on uwb radar measurements. the method includes, for each respective centroid among the set of centroids: classifying the respective centroid as one among human movement and non-human movement, based on a set of features for the respective centroid satisfying a human-movement condition; and when the respective centroid is classified as the human movement, determining a two-dimensional (2d) location of human movement based on the uwb radar measurements. the method includes updating a current state value that indicates whether a human presence is detected inside boundaries of a 3d space, based at least in part on the classification of each of the respective centroids among the set of centroids.
