External Display Graphical Representation via Logical Data Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing patient-monitoring systems face challenges in displaying comprehensive medical information on built-in displays, leading to the need for external displays, where current methods either transmit excessive data or result in user interface inconsistencies between the internal and external displays.
Innovation Solution
A method that processes monitoring data to generate logical communication data for an external display, using a display management device to recreate domain-specific graphical representations with minimal data transmission, ensuring consistency in user experience and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If complete graphical data is transmitted to the external display, then the user interface consistency is improved, but the data transmission bandwidth increases significantly
Solution Approach 1:
The patent extracts only the essential logical data elements needed to reconstruct the graphical representation on the external display, rather than transmitting the complete graphical data set. This selective extraction of necessary information reduces bandwidth requirements while maintaining interface consistency.
Solution Approach 2:
The external display device reconstructs the graphical representation by processing received logical data through a display management device that replicates the rendering logic, creating a copy of the visual output without requiring transmission of the actual graphical data.
2Quantity of substance
If only raw data is transmitted to the external display, then the data transmission bandwidth is reduced, but the user interface consistency deteriorates
Solution Approach 1:
The patent introduces logical data as an intermediary representation that carries essential structural and semantic information between the patient monitor and external display. This intermediate format enables reconstruction of the original graphical interface while requiring minimal transmission bandwidth.
Solution Approach 2:
The display management device on the external display processes the logical data through parameter transformations to regenerate the graphical representation, changing the data from a compact logical format back to the visual presentation format needed for consistent user interface display.
3Productivity
If a complete second user interface is implemented on the external display, then the data processing capability is improved, but the control functionality diverges from the original patient monitor
Solution Approach 1:
The display management device on the external display is designed to universally process logical data from the patient monitor, enabling the external display to function as an extension of the original system while maintaining consistent control semantics across different display devices.

AI summary
Technique for deriving a graphical representation of domain-specific display-objects on an external display (13) within a patient-monitoring system (1), in which only a small amount of data has to be transmitted to the external display device (3) and at the same time the user of the external display (13) gets the same “look and feel” as he is used to from the built-in display (12) of a patient monitor (2).
