Solution Overview

Problem

Existing sensor systems face challenges in seamlessly transitioning between multiple external sensor transceivers without losing measurement information or calibration parameters.

Innovation Solution

The system employs a method where the sensor receives a unique identification code from an external transceiver and determines if it is a new transceiver. If so, the sensor stores the ID and conveys stored measurement information to the new transceiver.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the sensor system allows multiple external sensor transceivers to be used, then the adaptability and ease of operation are improved, but the loss of measurement information and calibration parameters occurs

Engineering Contradiction:

Improveability to use multiple external sensor transceiversVSAvoidloss of measurement information and calibration parameters

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The sensor performs preliminary actions by storing measurement information and calibration parameters in non-volatile memory before the external sensor transceiver changes. When a new transceiver is detected, the sensor automatically transfers the stored data to the new transceiver, preventing information loss that would otherwise occur during the transition.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The sensor acts as an intermediary between multiple external sensor transceivers and the analyte measurement system. It maintains a repository of measurement information and calibration parameters, mediating the transfer of this data between different transceivers to ensure continuity of operation without information loss.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the sensor automatically transfers data to new transceivers, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:

Improveseamless transition between transceiversVSAvoidcomplexity of transceiver identification and data transfer mechanisms

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The sensor performs self-service by automatically detecting when a new external sensor transceiver is connected and autonomously transferring the necessary measurement information and calibration parameters. This eliminates the need for manual data transfer operations by the user, simplifying the operation despite the added automated functionality.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The sensor uses feedback mechanisms to detect the presence of external sensor transceivers and their identification codes. Based on this feedback, the sensor determines whether a transceiver is new or existing and automatically initiates the appropriate data transfer protocol, enabling seamless operation through automated decision-making.

Inventive Principle:

Principle #23Feedback

AI summary

Methods, sensors, and systems that prevent or reduce data loss when more than one external sensor transceiver is used with a sensor. A sensor may receive a transceiver identification (ID) of an external transceiver conveyed from the external transceiver and determine whether the received transceiver ID is a new transceiver ID. If sensor determines the received transceiver ID to be a new transceiver ID, the sensor may store the received transceiver ID in a nonvolatile storage medium of the sensor and convey, using the sensor, measurement information stored in the nonvolatile storage medium to the external transceiver.
