Fluid Cooling Link Codes for False-Alarm Leak Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing networked systems for fluid cooling in computing devices are vulnerable to interference in communication links, leading to false positives and false negatives in leakage detection, which can cause significant operational issues such as device failure, data loss, and safety hazards due to uncontrolled shutdowns.
Innovation Solution
Implementing a communication protocol that embeds a repeating cyclic codeword into messages between leakage detection sensors and a reservoir and pumping unit, using Maximum Distance Separable (MDS) codes and error-correcting codes (ECCs) to detect and correct interference, ensuring the authenticity of leakage detection signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a communication protocol without error detection is used, then the device complexity is reduced, but the reliability of leakage detection signals deteriorates due to vulnerability to interference
Solution Approach 1:
The patent introduces an intermediary error-detecting code (cyclic redundancy check or similar) that mediates between the simple communication protocol and the need for reliable signal transmission. This code is inserted into the communication stream between the leakage detection sensor and the reservoir and pumping unit, allowing interference to be detected without fundamentally changing the protocol structure.
Solution Approach 2:
The error-detecting code is prepared and inserted into the communication message before transmission occurs. This preliminary encoding allows the system to proactively protect against interference rather than reacting to errors after they occur, improving reliability while maintaining protocol simplicity.
2Reliability
If error-detecting codes are inserted into communication messages, then the reliability of leakage detection signals is improved, but the device complexity increases
Solution Approach 1:
The patent uses simple, computationally inexpensive error-detecting codes that can be quickly generated and processed. These codes act as disposable protective layers that are easily created and verified without requiring complex processing resources, thus improving reliability while minimizing the increase in device complexity.
3Reliability
If interference detection is implemented, then the occurrence of false alarms is reduced, but the processing time increases
Solution Approach 1:
The patent implements partial error detection by checking only critical portions of the communication message or using simplified error-detecting codes that provide adequate protection without requiring full exhaustive verification. This approach reduces false alarms while keeping processing time increases minimal.
4Measurement precision
If repeating cyclic codewords are used for interference detection, then the measurement precision of message integrity is improved, but the device complexity increases
Solution Approach 1:
The patent uses repeating cyclic codewords that are periodically inserted into the communication stream. This periodic structure allows the receiving end to easily synchronize and detect the codewords through simple pattern recognition, improving measurement precision of message integrity while avoiding complex implementation requirements.

AI summary
Systems, apparatuses and methods provide technology that identifies a codeword associated with a fluid cooling system and a network system, generates a status update with the network system, embeds the codeword as a repeating cyclic codeword in a message containing the status update, transmits the message from the network system to the fluid cooling system over a data link, receives the message at the fluid cooling system, and determines, with the fluid cooling system, whether interference is inserted into the message based on the repeating cyclic codeword in the message.
