AED Standby Status Display via Low-Power Processor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable automatic external defibrillators (AEDs) consume significant power when displaying status information, require users to navigate through complex menus, and often need to be fully powered up, leading to inefficiencies and delays, especially in non-medical environments where AEDs are frequently checked in standby mode.
Innovation Solution
A portable AED with a low-power standby processor that allows for rapid status information display on a video screen via single-button activation without entering a fully operational state, using a graphical user interface and touch-screen or button inputs, which conserves battery power and eliminates the need for complex menu navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the AED fully powers up to display status information, then comprehensive status information can be displayed, but significant battery power is consumed
Solution Approach 1:
The patent segments the power consumption into two distinct modes: a low-power standby mode for basic status display and a full operational mode for complete system functionality. The status display function is separated from the full system operation, allowing users to obtain essential information without activating all system components.
Solution Approach 2:
The patent implements partial action by providing sufficient status information display functionality without requiring full system power-up. The display can show critical status parameters (battery level, operational status, last usage date) using only the necessary minimal processing power, rather than requiring the complete AED system to be activated.
2Loss of information
If the AED requires full power-up and menu navigation to display status information, then comprehensive status can be obtained, but significant time is consumed
Solution Approach 1:
The patent applies preliminary action by pre-configuring the display to show status information immediately upon button press in standby mode, without requiring prior full power-up or menu navigation sequences. The system is prepared in advance to provide quick status access through a dedicated button that triggers immediate display of critical parameters.
Solution Approach 2:
The patent extracts the status display function from the full operational sequence, creating an independent quick-access pathway. By separating status information retrieval from the complete system initialization and menu navigation process, users can obtain essential status data through a simplified single-button interface that bypasses time-consuming full power-up procedures.
3Reliability
If the AED is checked frequently in standby mode, then operational status can be monitored, but battery life is reduced
Solution Approach 1:
The patent implements periodic action by enabling frequent standby mode status checks without depleting battery life. The low-power display can be activated periodically to show status information, then the system returns to standby mode, creating a sustainable cycle of monitoring that does not drain the battery completely.
Solution Approach 2:
The patent applies partial action by providing just enough power for essential status monitoring in standby mode, rather than full system operation. This partial power activation allows frequent checks of critical parameters (battery level, operational status) while consuming minimal energy, thereby extending overall battery life.

AI summary
A video display coupled to an automatic external defibrillator (AED) and capable of full-motion video can support added functionality of the AED. One advantage of the video display is that it can be used to present standby status information of the AED quickly to an AED operator while the AED is in a low power standby mode or non-operative state. The video display may present status information in response to touching the display or activating a button while the AED is in a non-operative state. When the AED is in an operative state, such as during a rescue, the display may comprise a graphical user interface that may be navigated using touch-screen technology or buttons built into the AED. During a rescue, the video display may present live or stored electrocardiograms (ECGs) and instructions for operating the AED.
