Hifi Announces New HDS 3.0 System and Three New Patent Awards

Advanced HDS platform supporting industry with continued innovations

CALGARY, Alberta, April 23, 2025 – Hifi Engineering Inc. (“Hifi”), a leader in machine learning enabled distributed fiber optic sensing technology for asset monitoring, has commercially released the new HDS 3.0 version of their patented high fidelity distributed sensing (HDS™) system.  Hifi’s innovative fiber optic based HDS technology is a next generation platform capable of providing real time event detection using integrated acoustics, temperature, and vibration / strain. By leveraging advanced machine learning on data from Hifi’s specialized fiber optic sensing cables on a fully distributed basis, the technology provides for comprehensive integrity monitoring of pipelines. HDS not only senses leaks in real time, but also captures other integrity, anomaly and operating conditions. Specific advancements in the underpinning machine learning algorithms have enabled pipeline operators to support a broad set of operational applications, ranging from pig tracking and thermal insulation mapping to deep fake digital alarm verification and validation as well as cumulative pipeline strain reporting.  

“We are very pleased to be releasing the newly developed HDS 3.0 system platform” said Ehsan Jalilian, Hifi’s Vice President and Chief Information Officer. “HDS 3.0 comes complete with Hifi’s newest advanced machine learning algorithms for preventative and predictive event detection and comprehensive integrity monitoring, making it the most innovative platform for multiple types of pipelines and product types.  It is also CO2 and hydrogen ready, which leverages the cutting-edge aspects of HDS for not just leak detection but applications unique to these products such as water hammer effect, turbulent flow at extremely high / super critical pressures, and potential free water formation.”

Improvements in the HDS 3.0 system platform include:

• Increasing monitoring range, significantly reducing the required optical hardware footprint and ultimately improving economics for long distance projects. The new design allows monitoring for distances  in excess of 100 km from a single station.
• State of the art analog and digital signal processing for maximal signal to noise ratio.
• Advanced data analysis and diagnostics data collection from new machine learning algorithms for system performance optimization. 

Hifi also announced the following new patent awards:

• Methods and System for Detecting Dynamic Strain (US 12,196,635)
• Methods and Systems for Providing Access to Interferometric System Data (US 12,163,815)
• Methods and Systems for Tracking an Object Moving Along a Conduit (US 12,253,204)

“Hifi is very proud to have been recognized with these patent awards” said John Hull, Hifi’s Founder and Chief Technology Officer. “These important pillars of our intellectual property underscore Hifi’s commitment to continuous improvement through our technology development roadmap.”
