Equipment Interface Unit for Heart Rate Data Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing physical exercise devices face challenges in accurately and efficiently transferring user exercise data to a network storage, particularly in determining the correct user account for storing heart rate measurement data, especially when multiple users share the same equipment interface unit.
Innovation Solution
A system where a measurement device attached to the user's body transmits heart rate data wirelessly to an equipment interface unit, which then streams the data to a server computer using short-range communication protocols like Bluetooth or ANT, with the device identifier associating the data with the correct user account, enabling real-time processing and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple users share the same equipment interface unit, then device versatility and user accessibility are improved, but the complexity of accurately associating measurement data with the correct user account increases
Solution Approach 1:
The patent introduces an equipment interface unit as an intermediary component that mediates between the measurement device and multiple user accounts. This interface unit receives measurement data from the measurement device and automatically transfers it to the appropriate user account on the server based on device identifiers, eliminating the need for complex manual user selection and resolving the contradiction between multi-user accessibility and data association accuracy.
Solution Approach 2:
The system enables automatic self-service data transfer where the equipment interface unit autonomously identifies the correct user account using device identifiers and transfers measurement data without requiring user intervention. This self-service mechanism simplifies the multi-user data association process while maintaining high accuracy in matching data to the correct user account.
2Productivity
If measurement data is transferred in real-time to a server, then data processing speed and performance metric computation are improved, but the network dependency and potential data transfer failures increase
Solution Approach 1:
The patent implements preliminary local storage of measurement data in the equipment interface unit before transfer to the server. This preliminary action ensures that data is captured and stored locally even when network conditions are poor or unavailable, and subsequent transfers occur when connectivity is restored, thereby maintaining high data transfer efficiency while compensating for network reliability issues.
3Measurement precision
If device identifiers are used to associate measurement data with user accounts, then data association accuracy is improved, but the requirement for unique device identification and system configuration complexity increases
Solution Approach 1:
The patent employs a universal device identifier system that can be implemented across multiple measurement devices and user accounts. The equipment interface unit uses these identifiers in a multi-functional manner to associate data with correct users, manage device connections, and coordinate transfers, thereby achieving high identification accuracy while avoiding the need for complex device-specific configuration through standardized identifier management.

AI summary
In this document, a system for processing heart rate measurement data measured during a physical exercise of a user is described. The system comprises a server computer configured to: associate, during a registration procedure for a measurement device of a user, a device identifier of the measurement device with a user account of the user stored in the server computer; receive a device identifier and real-time heart rate measurement data over a network connection; identify the user's measurement device from the received device identifier; store the received heart rate measurement data to the user account of the user on the basis of the association between the received device identifier and the corresponding user account;compute, repeatedly during the physical exercise from the received heart rate measurement data, advanced performance data comprising at least one value which accumulates during the physical exercise; and transmit the computed advanced performance data to the equipment interface unit over the network connection during the physical exercise.
