Abstract: Systems and methods are provided for multi-domain vulnerability assessment. An exemplary system includes a plurality of wireless signal detectors, wherein each of the wireless signal detectors is configured to detect wireless signals of a respective wireless signal protocol of a plurality of wireless signal protocols. The wireless signal detectors transmit the signal data to a data processor that classifies the plurality of devices based on the wireless signal data, determines one or more device vulnerabilities associated with the plurality of devices based on the classification of the plurality of devices, and determine a plurality of device risks for the plurality of devices based on the plurality of device vulnerabilities.

Abstract: A coupling for connecting one or more pipes or conduits. The coupling includes at least one wedge-shaped gasket extending around the coupling. The wedge-shaped gasket includes an outer sloped or inclined surface, an inner surface, and a pair of opposed ends where one end is higher than the other. In use, a pipe, duct or conduit is inserted over one end portion of the coupling such that as the pipe or conduit is moved or slipped over the wedge-shaped gasket, the gasket compresses and forms a seal between the coupling and a portion of the inner surface of the pipe or conduit.
