Implant Node Hub ID Partitioning for Wireless Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless medical implants face significant power consumption challenges due to frequent wake-ups for communication with external controllers, leading to battery drain and inefficiency, especially when connecting with irrelevant or 'alien' hubs, which is not power-efficient and may violate regulatory requirements.
Innovation Solution
The implant node intelligently identifies and connects only with designated hubs by partitioning Hub ID space into subsets for emergency, doctor's office, and home hubs, allowing it to selectively respond to connection invitations based on pre-configured HID values, reducing unnecessary power usage during frequent wake-ups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the implant wakes up frequently to listen for connection signals, then it can detect relevant hubs promptly, but power consumption increases
Solution Approach 1:
The patent segments the Hub ID address space into multiple subsets (e.g., first subset for home hubs, second subset for doctor's office hubs, third subset for emergency hubs). The implant node maintains separate filter lists for each subset, allowing it to selectively process connection invitations based on the current context and required connection type, rather than responding to all hubs equally.
Solution Approach 2:
The patent pre-configures the implant node with filter lists containing hub identifiers from different subsets during initialization or setup. These filter lists are prepared in advance, enabling the implant to quickly determine whether to respond to connection invitations without performing complex real-time analysis, thus reducing power consumption during operation.
2Adaptability or versatility
If the implant responds to all connection invitations, then it ensures connectivity with any hub, but power is wasted on irrelevant 'alien' hubs
Solution Approach 1:
The patent divides the hub address space into distinct subsets organized by location and function (home, doctor's office, emergency). The implant maintains separate filter lists for each subset, allowing it to adapt its response behavior based on which subset the incoming connection invitation belongs to, ensuring compatibility with relevant hubs while filtering out irrelevant ones.
Solution Approach 2:
The patent applies different response characteristics to different hub subsets. The implant node is configured to respond to connection invitations from hubs in its current context's subset (e.g., home hub subset when at home) while ignoring or differently handling invitations from other subsets, optimizing energy usage based on local conditions.
3Use of energy by moving object
If the implant uses a simple filter list for hub identification, then power consumption is reduced, but the ability to distinguish between different hub types is limited
Solution Approach 1:
The patent segments the filter mechanism into multiple context-specific filter lists (first filter list for home hubs, second filter list for doctor's office hubs, third filter list for emergency hubs). Each filter list contains hub identifiers specific to that context, enabling the implant to maintain simple, efficient filtering while supporting multiple hub types and locations.
Solution Approach 2:
The patent creates a universal filter list structure that can serve multiple functions: home hub identification, doctor's office hub identification, and emergency hub identification. The same filter list mechanism is reused across different contexts, maintaining simplicity while achieving versatility through the segmented organization of hub identifiers within the lists.
Data Source
AI summary
A system and method for providing wireless communications between a medical controller hub and an implant node are disclosed. The hub transmits signals to facilitate communication connections with the node. The signals include connection invitation polls with identification parameters. A node monitors the hub's transmissions for the connection invitation polls. When a poll is detected, the node compares the identification parameters to a list of preferred identification values. If the received identification parameter is on the preferred list, and the node and hub are not already connected, then the node responds to the connection invitation poll. If the received identification parameter is not on the preferred list, then the node continues to monitor hub transmissions for other connection invitation polls that include identification parameters that are on the preferred list.
