In-Vivo Sensing Device Identifier Code for Data Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vivo sensing devices, such as ingestible capsules, face challenges in data communication to external recorders, where multiple devices within communication range can confuse data analysis by transmitting data to the wrong recorder, leading to incorrect association of image data with the correct device.
Innovation Solution
Incorporating an identifier code, such as a numeric or alphanumeric string, into the in-vivo sensing device, which is communicated to the data recorder along with the data, allowing the recorder to associate received data with the specific device using methods like matching internal and external identifier codes, RSSI thresholds, or frame counters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple in-vivo sensing devices are within communicating distance of a data recorder, then the system can handle multiple patients or devices simultaneously, but data from different devices may be incorrectly associated with the wrong recorder, leading to confusion during analysis
Solution Approach 1:
The patent implements a feedback mechanism where the data recorder receives identifier codes from in-vivo sensing devices, compares them with stored identifier codes, and uses this feedback to determine which device's data to store. This closed-loop identification system ensures that even when multiple devices are present, the recorder can reliably associate data with the correct device by continuously monitoring and responding to identifier code transmissions.
Solution Approach 2:
The patent introduces an identifier code as an intermediary element that mediates between the in-vivo sensing device and the data recorder. This identifier code acts as a unique signature or tag that allows the recorder to distinguish between multiple devices without requiring direct complex communication protocols, thereby maintaining data association accuracy while supporting multiple devices simultaneously.
2Reliability
If an identifier code system is implemented to distinguish between multiple devices, then data association accuracy is improved, but the device complexity increases due to additional identification and communication components
Solution Approach 1:
The patent applies universality by using a standardized identifier code format and communication protocol that can be implemented across multiple devices and recorders. This universal approach allows the same identification mechanism to handle various device types and scenarios, reducing the need for device-specific complex identification systems while maintaining high data association accuracy.
Solution Approach 2:
The patent employs simple, inexpensive identifier codes that can be easily generated and transmitted. These identifier codes function as disposable information elements that are transmitted briefly during the data association process, then discarded or replaced, avoiding the need for complex, permanent identification hardware while achieving reliable device distinction.
Data Source
AI summary
An in-vivo sensing device for capturing sensed data of the gastrointestinal tract, or other body lumens or cavities of a patient, and for transmitting the sensed data to a data recorder external to the patient. The in-vivo sensing device has an identifier code associated with it. The sensed data may be transmitted to the data recorder together with the identifier code so that the received sensed data can be correlated with the in-vivo sensing device.
