Abstract: A railcar fouling detection system is disclosed herein that is configured to monitor a railway foul zone between a switch and a foul line by detecting railway vehicles moving within or through the foul zone and determining whether railway vehicles are positioned within the foul zone based on information obtained by the one or more sensors. In some embodiments, the railcar fouling detection system may be configured to determine whether a railway vehicle is positioned within the foul zone by counting the number of wheels (or railway vehicles) entering and exiting the foul zone. The railcar fouling detection system may be configured to provide a visual indication of whether or not a railway vehicle is presently within the foul zone and/or provide a notification to locomotives in response to detecting a railway vehicle positioned within the foul zone.

Abstract: A switch gap detection system is disclosed herein that is configured to monitor a switch installed on a railway, detect a switch gap, and notify a train operator or otherwise take action to prevent a derailment, accident, or other dangerous situation. The switch gap detection system may include one or more switch gap sensors installed on or adjacent to a rail at a location proximate to a switch. The one or more switch gap sensors may be configured to determine a status of the switching points on the switch (e.g., open, closed, or switch gap detected). If the one or more switch gap sensors detect a switch gap, a notification may be provided to a train operator, for example, in the form of an audible and/or visual alert. In some embodiments, a signal may also be sent to automatically stop the train to prevent a derailment.

Abstract: A crane collision avoidance system is disclosed herein that is configured to monitor a crane and an environment surrounding the crane. The crane collision avoidance system may include one or more devices or sensors that are selectively attached to a crane. In various embodiments, the crane collision avoidance system may include a computer system configured to use images or information obtained via the devices or sensors to monitor a crane operator's blind spots and movement of the crane and its components, detect potential collisions with danger objects within the environment surrounding the crane, detect counterweight movement, monitor a load zone, detect when a boom or any other component of a crane has become energized, and/or otherwise provide improved situational awareness to a crane operator.
