ADS-B Receiver Module Caching for Sleep Mode Data Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ADS-B systems on mobile devices, such as iPads, often miss important weather updates due to battery-saving 'sleep' mode, leading to outdated information when awakened, posing risks for pilots navigating through inclement weather.
Innovation Solution
An ADS-B system comprising a receiver module that buffers data transmissions from ground stations and allows mobile devices to access cached data, including multiple generations of weather broadcasts, enabling the creation of animated displays and ensuring data availability upon device wake-up.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the mobile device enters sleep mode to conserve battery power, then energy consumption is reduced, but the device misses weather broadcast updates
Solution Approach 1:
The receiver module continuously receives and caches weather broadcast data in advance before the mobile device needs it. When the device wakes from sleep mode, the cached data is already available, eliminating the need for continuous reception during sleep periods while ensuring no updates are missed.
Solution Approach 2:
The receiver module acts as an intermediary between the weather broadcast system and the mobile device. It buffers and stores weather data, then transfers it to the device when requested, allowing the device to remain in sleep mode while still accessing current weather information.
2Loss of information
If the mobile device remains awake to receive continuous weather updates, then information currency is improved, but battery power consumption increases
Solution Approach 1:
Weather data is cached in advance by the receiver module before the device needs it. This preliminary caching allows the device to wake periodically and receive pre-prepared updates without needing to remain continuously awake, significantly reducing power consumption while maintaining information currency.
Solution Approach 2:
Instead of continuous operation, the system uses periodic wake-up cycles where the device requests cached data at intervals. The receiver module continuously prepares data in the background, and the device interacts periodically, reducing overall energy consumption while maintaining update currency.
3Loss of information
If the device wakes from sleep mode to check weather, then information availability is improved, but the device may have missed recent broadcasts
Solution Approach 1:
The receiver module continuously receives and stores weather broadcasts in advance, building a cache of recent data. When the device wakes from sleep mode, this pre-cached data is immediately available, eliminating the time delay that would otherwise exist while the device attempted to catch up on missed broadcasts.
Solution Approach 2:
The receiver module serves as a buffer and intermediary, storing multiple generations of weather data. When the device wakes, it can request and receive the most recent cached data immediately, with the receiver module having already performed the time-consuming reception and storage operations in advance.
Data Source
AI summary
An electronic system comprising a receiver module and a mobile device, whereby the receiver module is capable of receiving data transmissions from a network of ground stations and buffering the data for future use, and whereby the receiver module provides a means for making requests for access to this buffered data, and the mobile device is capable of generating requests to the receiver module in order to access the buffered data and of displaying the data or playing the data to an operator.
