Personal Event Data Recorder Mobile Device Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current event data recorders in aircraft and vehicles do not provide data regarding individuals involved in adverse events, and individuals may not recall event details accurately after experiencing an adverse event.
Innovation Solution
A personal event data recorder (PEDR) system comprising a mobile device with sensors, a processor, and memory, capable of storing event data triggered by user-defined settings, and communicating with external sensors and a wireless network for data storage and emergency alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional event data recorders (FDR, CVR, EDR) are used to record crash data, then vehicle/aircraft operational data is captured, but personal event data and individual perspective information are not recorded
Solution Approach 1:
The patent combines multiple sensing capabilities (accelerometer, gyroscope, microphone, camera, GPS) into a single mobile device platform, creating an integrated personal event data recorder that captures both environmental sensor data and personal perspective information simultaneously, eliminating the need for separate recording devices
Solution Approach 2:
The mobile device is designed to perform multiple functions: it acts as both a traditional EDR (recording acceleration, impact, braking data) and a personal event recorder (capturing audio, video, GPS location, and user-selected metrics), allowing one device to replace multiple specialized recording systems
2Reliability
If sensors continuously monitor all parameters, then complete event data is captured, but energy consumption and device complexity increase
Solution Approach 1:
The system performs preliminary configuration where users pre-select which metrics they want tracked and set sensitivity thresholds before events occur. During actual events, the system only activates recording when triggers are met, avoiding continuous monitoring while ensuring relevant data is captured
Solution Approach 2:
Instead of continuous recording, the system uses periodic sampling at predetermined intervals and activates sensors only when event triggers are detected, such as acceleration exceeding thresholds or impact events, thereby reducing overall power consumption while maintaining reliable event capture
3Adaptability or versatility
If multiple sensors and settings are integrated into the mobile device, then personal event data recording capability is enhanced, but device complexity increases
Solution Approach 1:
The system provides dynamic configurability where users can adjust sensitivity thresholds, select which metrics to track, and modify recording parameters based on their specific needs. The device adapts to different user preferences and event types rather than requiring fixed complex configurations for all scenarios
Solution Approach 2:
The mobile device leverages its existing self-service capabilities (processor, memory, display, user interface) to manage the complexity of multiple sensors and settings, allowing users to configure and control the system themselves without requiring additional specialized components or expert intervention

AI summary
A personal event data recorder (PEDR) is provided. The PEDR may be integrated within a mobile communications device or may be provided as a separate add-on device operatively linked to the mobile communications device. The PEDR is configured to activate a number of sensors based upon an event trigger and monitor and record event data from the sensors. The PEDR is further configured to store the recorded event data in one of a memory and a network database. The PEDR may also be utilized with a secondary sensor system such as, but not limited to, a vehicle sensor system or a security sensor system.
