Example implementations described herein are directed to detection of anomalous events and locations on the transmission power system using phasor management unit (PMU) data, which provides information to grid operators for online decision support. From the high-resolution time synchronized PMU data, the transient abnormal events can be monitored and locations can be disclosed to operators for remedy actions. Utilization of PMU information for such decision support compliments operation practices relying on supervisory control and data acquisition (SCADA) measurements at much lower data resolution. Accurate identification of event locations can further advise grid operators the root cause of disturbances and illuminate possible cascading failures. Implementations of the proposed technology may improve the resilience and reliability of the transmission power systems.

A conveyor belt system includes a spiral conveyor belt, a spiral conveyor cage structure adjacent the spiral conveyor belt, an RFID sensor integral to the spiral conveyor belt, and a plurality of antennas of a reader, the antennas being attached to the spiral conveyor structure. A method of using the conveyor belt system includes rotationally displacing the spiral conveyor belt relative to a portion of the spiral conveyor cage structure, obtaining and storing first time stamp data when the RFID sensor passes one of the plurality of antennas, and obtaining and storing second time stamp data when the RFID sensor passes another one of the plurality of antennas.

A structure which ensures a movement of a seal lip disposed in a seal lip is realized by preventing foreign matters from permeating a seal internal space between a slinger and a seal ring. A labyrinth seal is disposed between an outer peripheral edge of a rotary side annular portion configuring the slinger and an inner peripheral surface of a stationary side cylindrical portion of a metal insert configuring the seal ring. In addition, a thickened portion is formed in a portion of an elastic member configuring the seal ring over an entire periphery. An auxiliary seal lip whose rigidity is lower than that of respective seal lips is disposed in the thickened portion over the entire periphery. The auxiliary seal lip prevents the foreign matters from adhering to the seal lip, and prevents the movement of the seal lip from being hindered.
