Abstract: Devices and techniques are generally described for an edge computing system. In various examples, the edge computing system may comprise a host kernel comprising a kernel-based virtual machine hypervisor. In some examples, the edge computing system may comprise virtualization software effective to communicate with the kernel-based virtual machine hypervisor to execute guest virtual machines. In various further examples, the edge computing system may comprise an engine virtual machine with access to at least one hardware component. The edge computing system may further comprise a control plane virtual machine. The control plane virtual machine may include components effective to receive a first request and determine an application corresponding to the first request, and a virtual machine manager effective to control the virtualization software to generate a virtual machine, configured in accordance with a configuration specific for the virtual machine, for executing the application.

Abstract: A pipeline inspection and defect mapping system includes a pig having an inertial measurement unit and a pipeline inspection unit for recording pig location and defect detection events, each record time-stamped by a highly precise onboard clock. The system also includes several magloggers at precisely known locations along the pipeline, each containing a fluxgate magnetometer for detecting the passage of the pig along the pipeline and further containing a highly precise clock synchronized with the clock in the pig. The locations of the various magloggers are known in a north/east/down coordinate system through a differential global positioning satellite process. Finally, a postprocessing off-line computer system receives downloaded maglogger, inertial measurement, and odometer data and through the use of several Kalman filters, derives the location of the detected defects in the north/east/down coordinate frame. Consequently, a task of identifying sites for repair activity is much simplified.
