Signal Synchronization Using Domain Knowledge Without Time Stamps

The patent applies preliminary action by pre-defining domain knowledge models that describe expected temporal relationships between signals from different data sources. These models are established before actual data recording occurs, enabling post-hoc temporal alignment without requiring synchronized clocks during data collection. The domain knowledge models serve as pre-prepared reference frameworks that guide the temporal linking process.

The patent introduces domain knowledge models as an intermediary between raw signals from independent data sources and the temporal alignment process. These models act as mediators that translate physical domain understanding into temporal relationship constraints, enabling the system to synchronize signals without direct time synchronization hardware. The intermediary models bridge the gap between independent data sources and unified temporal analysis.

The patent replaces mechanical/time-synchronization hardware interfaces with a software-based solution using domain knowledge models. Instead of adding physical synchronization interfaces to machine control systems, the invention uses computational models that represent temporal relationships based on physical domain understanding. This substitution eliminates the need for additional hardware while achieving temporal alignment capability.

The system performs self-service by using its own domain knowledge models to automatically establish temporal relationships between signals. The analysis device autonomously applies pre-defined physical models to align signals from independent data sources without requiring external synchronization infrastructure. The system serves its own temporal alignment needs through embedded domain knowledge rather than external control systems.
