Embedded Transient Scanning for PCB Pulse Detection

The patent pre-calculates and stores susceptibility scan data during system setup or manufacturing, creating a reference database of electromagnetic field distributions. During actual transient event detection, the system queries this pre-computed data instead of performing new scans, reducing detection time from hours to seconds while maintaining accurate localization of transient pulse origins.

The patent transitions from time-domain scanning (sequential measurement at different positions) to spatial-domain querying (instant retrieval of pre-mapped field distributions). By pre-mapping the electromagnetic susceptibility landscape in three-dimensional space and storing it as a reference model, the system can instantly query transient origins without physical scanning, effectively adding a spatial dimension to the detection approach.

The patent performs comprehensive electromagnetic susceptibility characterization during manufacturing when the system is accessible and can be properly instrumented. This pre-scanning creates a permanent reference model that eliminates the need for expensive precision scanning hardware during field operation. The one-time investment in characterization replaces ongoing needs for costly measurement equipment.

The patent creates a digital copy or model of the electromagnetic field susceptibility distribution and stores it in memory. This virtual model serves as a reference for all subsequent transient detections, replacing the need for physical scanning hardware. The digital twin of the electromagnetic environment enables accurate transient localization without requiring expensive measurement instruments in the field.

The patent implements electromagnetic susceptibility characterization as a universal capability that works through existing system interfaces without modification. The same susceptibility model serves multiple purposes: characterizing transient susceptibility, localizing transient origins, and guiding protection device placement. This multi-functional approach eliminates the need for invasive probing while maintaining access to internal node information through the pre-created reference model.

The patent replaces mechanical/invasive probing methods with electromagnetic field-based characterization. Instead of physically accessing internal nodes through disassembly, the system uses electromagnetic susceptibility scanning to create a virtual model of internal node vulnerability. This non-contact, non-invasive approach maintains system integrity while providing equivalent or superior information about internal node susceptibility.
