Abstract From the Canadian patent

The invention is an apparatus, method and system for time synchronizing data from various sensor types (Sensor Node 1-Sensors Node 2) that enables data fusion and transport. To provide capability the invention utilizes an inverted Passive Optical Network (iPON) approach (Fig.2B) for synchronous communication. The invention introduces an inverted Passive Electrical Network (iPEN) that extends the iPON approach (Fig. 2B). Data that are in a common format with embedded tune synchronization information can easily be integrated of fused and transported over such communication links. The invention provides the ability to merge and aggregate data from a wide range of disparate sensors (Sensor …
