Medical Device UTC Offset Verification via Relay Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical communication systems face challenges in efficiently transmitting and receiving data between medical facilities in different time zones, as they require conversion of local time information, which can be complex and prone to errors.
Innovation Solution
A communication method using UTC time information, where a medical device transmits a verification signal with time information to a server apparatus, which determines if the device includes a UTC offset and communicates the result to the device, enabling efficient data processing across time zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If local time information conversion is used for communication between medical facilities in different time zones, then data transmission between facilities is enabled, but the process becomes complex and error-prone due to time zone adjustments
Solution Approach 1:
The patent changes the time reference parameter from local time to UTC time. The server apparatus stores and manages time information in UTC format, and all time-related operations (scheduling, result reporting, etc.) are performed based on UTC time, eliminating the need for time zone conversion operations and reducing complexity while maintaining communication reliability between facilities in different time zones.
2Device complexity
If UTC time information is used for communication between medical facilities, then time zone conversion complexity is reduced, but verification of device UTC offset capability is required
Solution Approach 1:
The patent implements preliminary verification of the medical device's UTC offset capability through an automated handshake process. Before normal communication begins, the server apparatus sends a verification request to the medical device to determine whether it supports UTC offset information. Based on the verification result, the server apparatus automatically adjusts its communication strategy, either by requesting UTC offset information from the device or by providing its own UTC offset information, thus preparing the system in advance for efficient UTC-based communication.
3Adaptability or versatility
If medical devices in different time zones communicate using their local time, then each device operates independently, but coordination and scheduling between facilities become difficult
Solution Approach 1:
The patent implements a universal time reference system where UTC time serves as the common time basis for all medical facilities regardless of their local time zones. The server apparatus manages time information in UTC format and handles all scheduling, result reporting, and coordination operations based on this universal reference. This allows facilities to maintain their local time operations while achieving seamless coordination through the universal UTC time standard, effectively enabling multi-functional time handling.

AI summary
A verification signal transmission unit transmits a verification signal including time information indicating a current time to a server apparatus via a relay apparatus. The verification signal relay unit receives the verification signal from the medical device and transmits the verification signal to the server apparatus. The verification signal reception unit receives the verification signal, and the offset determination unit compares the time information included in the verification signal with a current time on the server apparatus in UTC time and determines whether the medical device includes a UTC offset in the time information. A determination result transmission unit transmits a result of determination related to a UTC offset to the relay apparatus or the medical device. A determination result reception unit receives the result of determination. A registration unit registers information related to the result of determination in a device information recording unit, mapping the information to device identification information identifying the medical device.
