Abstract: An apparatus and methods are provided for a portable mass airflow (MAF) training module configured to simulate an air intake into an internal combustion engine. An in-line blower draws an airflow through an air filter by way of a first air duct and a second air duct. A throttle assembly is coupled between the first air duct and the second air duct. The throttle assembly includes a throttle plate that may be rotated to regulate the airflow. The power output of the in-line blower is variable to simulate the air intake of various sizes of the internal combustion engine. A MAF sensor and a duct velocity sensor are configured to provide airflow information. The portable MAF training module enables a practitioner to select a desired throttle setting and observe a resultant mass airflow through the portable MAF training module that is measured by the MAF sensor.

Abstract: The present disclosure pertains to systems and methods for monitoring traveling waves in an electric power system. In various embodiments, a data acquisition subsystem may acquire electric power system signals. A traveling wave detection subsystem may detect two or more traveling waves based on the electric power system signals and determine a location of an event triggering the traveling waves. A traveling wave security subsystem may selectively generate a restraining signal based on the location of the event as within a blocking zone. A protection action subsystem may implement a protective action when the location is outside of a blocking zone. In various embodiments, a protective action will not be implemented for traveling waves launched from known locations of switching devices operating normally. Further, protective actions may be restrained if a magnitude of a traveling wave differs from an expected value based on a pre-fault voltage.
