Cloud, Edge and Device: Where Should Industrial AI Actually Run?
Latency, data volume, outages and security each push industrial AI work to a different tier. What runs best on the device, at the site and in the cloud.
Industrial Sensor Placement: Why Location Changes What You Can Detect
How signals travel from a machine fault to a sensor, why mounting acts like a filter, and a practical checklist for placing vibration and temperature sensors.
Transformer Condition Monitoring: Signals, Risks and Practical Constraints
How oil-filled transformers age, the signals that reveal their condition, how dissolved gas results are read, and the practical limits on monitoring a fleet.
False Positives in Predictive Maintenance: The Problem Nobody Should Ignore
Why good fault detectors still raise more false alarms than real ones, the base rate arithmetic, how to set thresholds by cost, and how to keep alerts trusted.
Machine Anomalies vs. Machine Failures: Why the Difference Matters
Anomaly, fault and failure are different things. The four jobs of machine health analysis, and one synthetic example followed from first sign to remaining life.
Inside an Industrial AI Sensor: The Architecture Behind NODE
The proposed architecture of NODE, function by function: sensing, signal conditioning, edge compute, buffering, secure links and the reasons for each.
Thermal Intelligence: Why Temperature Alone Doesn't Tell the Whole Story
Temperature is the most familiar machine measurement and often a misleading one. How thermal sensing works and why load, ambient and history matter.
Acoustic Monitoring: What Industrial Machines Reveal Through Sound
What sound and ultrasound reveal about machines, how acoustic sensing compares with vibration, and why background noise is the hardest part of the job.
