Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reconstructing the behavior of security operators during events, especially in indoor locations, provide only partial and limited reconstructions, necessitating a more reliable and efficient approach to correlate vital parameters and movements.
Innovation Solution
A method and apparatus that record and correlate environmental, inertial, and biometric signals using a detection apparatus worn by the individual, allowing for separate detection and mapping operations, with alignment of time series using dynamic time warping to reconstruct movements and posture after the event, and integrating biometric data for comprehensive reconstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If micro cameras are used to record security operations, then behavioral data can be captured, but the reconstruction remains partial and limited
Solution Approach 1:
The patent combines multiple detection apparatuses (micro camera, inertial sensors, biometric sensors) into an integrated system that simultaneously captures visual, motion, and physiological data. This merging of multiple data sources enables comprehensive behavioral reconstruction that overcomes the limitations of camera-only recording by providing synchronized multi-modal information about the operator's actions, movements, and vital parameters.
Solution Approach 2:
The detection apparatus is designed with multi-functionality, serving as both a recording device and a sensing platform. The same apparatus that captures video also integrates inertial measurement units and biometric sensors, allowing a single device to perform multiple functions: visual recording, motion tracking, and physiological monitoring. This universal design eliminates the need for separate systems and enables correlated analysis of all data streams.
2Reliability
If comprehensive sensors are integrated to capture all behavioral data, then reconstruction accuracy improves, but device complexity increases
Solution Approach 1:
The patent implements a nested structure where multiple sensing components are integrated within a compact detection apparatus worn by the operator. The inertial sensors and biometric sensors are nested within the same housing as the micro camera, creating a hierarchical integration where smaller sensing elements are contained within the overall detection system. This nesting approach reduces the physical footprint and simplifies the operator interface while maintaining comprehensive sensing capabilities.
Solution Approach 2:
The patent introduces a processing unit that acts as an intermediary between the multiple sensors and the external analysis system. This intermediary component receives raw data from all sensors, performs initial processing and synchronization, and outputs standardized behavioral reconstructions. The mediator simplifies the complexity by abstracting the multi-sensor integration details, allowing the system to function as a unified device despite containing multiple sophisticated components.
3Productivity
If separate detection and mapping operations are performed, then flexibility and resource efficiency improve, but time consumption increases
Solution Approach 1:
The patent performs the mapping operation separately from the detection operation, allowing the environmental map to be created in advance or independently of the actual security operation. By separating these operations, the system can prepare the spatial framework beforehand, reducing the processing burden during critical events. The detection apparatus only needs to record data relative to the pre-established map, significantly reducing real-time computational requirements and enabling faster response during operations.
