Adaptive Glucose Data Reception for Communication Interruptions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing continuous glucose monitoring systems (CGMS) face challenges in stable data transmission due to communication interruptions or resets, leading to incomplete or delayed glucose information delivery, which can be critical for diabetic patients.
Innovation Solution
A method is implemented where a terminal adjusts its data reception cycle in response to events like communication failures or resets, receiving biometric information at varied intervals, including filling data gaps and resuming transmission upon recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal continuously receives glucose information from the sensor transmitter at regular intervals, then real-time glucose monitoring is achieved, but data loss occurs when communication interruptions or resets happen
Solution Approach 1:
The terminal stores a predetermined number of glucose data points in advance before communication interruptions occur. This preliminary data storage ensures that when resets or communication failures happen, the terminal already has buffer data to display, preventing complete data loss and maintaining continuous monitoring display during transient failures
Solution Approach 2:
The system maintains a data buffer of predetermined size that acts as a cushion against communication failures. When interruptions occur, this pre-established data reserve protects against complete information loss, allowing the terminal to continue displaying glucose levels without gaps during the interruption period
2Loss of information
If the terminal waits for data after a reset occurs, then data completeness is improved, but response time to glucose changes is delayed
Solution Approach 1:
The terminal displays available glucose data immediately without waiting for complete data sets after a reset. Even if some data points are missing or incomplete, the system shows whatever data is currently available, ensuring rapid response to glucose changes while gradually updating as more data becomes available from the sensor transmitter
3Speed
If the sensor transmitter transmits glucose data continuously, then real-time monitoring is achieved, but energy consumption increases
Solution Approach 1:
The sensor transmitter transmits glucose data at periodic intervals rather than continuously. This periodic transmission reduces energy consumption by keeping the transmitter in low-power states between measurements while still providing timely glucose monitoring data to the terminal at regular intervals
Solution Approach 2:
The terminal initiates data requests and manages its own data buffering and display updates. The sensor transmitter simply responds to requests or transmits at predetermined intervals, allowing the terminal to control the timing and frequency of data exchanges, thereby optimizing energy usage across the system

AI summary
One embodiment may provide a method of providing biometric information including receiving biometric information at a first time interval; outputting the biometric information; when an event related to data reception occurs, receiving the biometric information at a second time interval different from the first time interval; and outputting the biometric information received at the second time interval.
