Abstract: A technique is directed to methods and systems of a dynamic geofence in a worksite environment. In some cases, cameras and sensors are placed on the machines to monitor the worksite and automatically create a geofence around a machine as it operates. The geofence can dynamically change as the machine navigates in the worksite. Machine operators or site personnel can receive an alert regarding the proximity of people or objects to the geofence around the machine. In some implementations, the machines are autonomous, semi-autonomous, or remote controlled from a modular and customized virtual cab. A remote-controlled machine can provide full machine maneuverability with the user at a safe distance from potentially hazardous environments. In some cases, the geofence is automatically created to cover the work area based on the semi-autonomous command assigned to the machine.

Abstract: A particulate trap regeneration system is provided, which may include a particulate trap having a filter medium configured to remove one or more types of particulate matter from an exhaust flow of an engine and a regeneration device configured to reduce an amount of particulate matter in the particulate trap, as well as a radio frequency-based particulate loading monitoring system configured to determine an amount of particulate matter trapped by the filter medium. The particulate loading monitoring system may include at least one radio frequency transmitting probe configured to transmit radio frequency signals of predetermined magnitude and predetermined frequency toward the filter medium and at least one radio frequency receiving probe configured to receive and measure the magnitude of received radio frequency signals that pass through the filter medium.
