Glucose Monitoring Signal Loss Alerts Using Two-Stage Persistence Timing

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing glucose monitoring systems fail to accurately and timely notify users of signal loss between the sensor transmitter and terminal due to communication failures, leading to potential user disturbance or missed notifications.

Innovation Solution

Implement a method where the terminal delays signal loss notifications for a first period of time after detecting a communication failure, followed by a second period to determine persistent signal loss, and then generates a notification only if the signal loss persists during this second period.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If the terminal provides notification about signal loss immediately when communication failure occurs, then the user is informed timely, but the user may be disturbed by frequent notifications

Engineering Contradiction:

Improvenotification timingVSAvoiduser disturbance

Core Design Contradiction:

Loss of timeVSObject-affected harmful factors

Solution Approach 1:

The terminal performs preliminary assessment of signal loss conditions before issuing notification. It determines whether signal loss has occurred and evaluates persistence criteria (first period and second period thresholds) before generating the notification, thereby avoiding premature or false notifications that would disturb the user.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The notification system dynamically adjusts its behavior based on the duration and persistence of signal loss. Instead of a static immediate notification, the system adapts the notification timing based on whether the signal loss persists beyond predetermined thresholds, balancing timely information provision with user comfort.

Inventive Principle:

Principle #15Dynamics

2Object-affected harmful factors

If the terminal delays signal loss notification to reduce user disturbance, then user disturbance is minimized, but the notification may not be provided timely

Engineering Contradiction:

Improveuser disturbanceVSAvoidnotification timing

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The terminal continuously monitors communication status and provides feedback on signal loss persistence. By evaluating whether signal loss continues beyond the first period and second period thresholds, the system determines the appropriate timing for notification, ensuring both timeliness and user comfort.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system changes the notification parameter (timing) based on the duration parameter of signal loss. When signal loss exceeds predetermined time thresholds, the notification is generated; otherwise, it is delayed or suppressed, optimizing the balance between timely information and user disturbance.

Inventive Principle:

Principle #35Parameter changes

3Measurement precision

If the terminal provides notification for any communication failure, then accurate signal loss detection is achieved, but false notifications may occur due to temporary failures

Engineering Contradiction:

Improvesignal loss detection accuracyVSAvoidnotification reliability

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The terminal performs preliminary determination of signal loss conditions by checking whether communication failure persists beyond predetermined thresholds (first period and second period) before generating notification. This preliminary assessment filters out temporary or transient communication failures, improving notification reliability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system incorporates time-based cushioning periods (first period and second period thresholds) before issuing notifications. These cushioning periods protect against premature notifications caused by temporary communication glitches, ensuring that only persistent signal loss conditions trigger alerts.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

One embodiment may provide a method of providing a notification of signal loss in a glucose monitoring system, the method including, when a communication failure occurs between a terminal and a sensor transmitter, delaying a signal loss notification for a first period of time by the terminal, when the communication failure persists for the first period of time, further determining whether signal loss persists for a second period of time by the terminal, when the signal loss persists for the second period of time, generating the signal loss notification by the terminal, and outputting, by the terminal, the signal loss notification to a user.
