Abstract: Systems and methods are provided for achieving vital ultra-wideband (UWB) based train control. Train-mounted units and wayside units that incorporate at least two separate and independent radios are used to obtain independent and separate ranging measurements in trains based on communications between the train-mounted units and wayside units. The communications includes communication of ultra-wideband (UWB) based signals.

Abstract: Systems and methods are provided for worker protection. The worker protection systems comprise a plurality of alert devices, comprising one or more wearable personal alert devices, each worn by a person (e.g., worker), and one or more companion alert devices that broadcast alerts or signals triggering alerts. The companion alert devices comprise vehicle-mounted alert devices, configured for operation on vehicles (e.g., trains), and wayside detection units, configured for placement on or near paths of the vehicles. The wayside detection units may be operable to autonomously detect and track the vehicles.

Abstract: A worker protection system may include a train-mounted unit for use on a train, and one or more wayside units, configured for placement on or near a track traversed by the train. Each of the train-mounted unit and the one or more wayside units may include a corresponding communication component, with one or more antennas, configured to transmit and/or receive wireless signals, with the signals comprise ultra-wideband (UWB) signals, and one or more circuits configured for processing signals and data, and for performing applications or functions relating to operations of the corresponding unit. The train-mounted unit may operate cooperatively with the one or more wayside units, to provide alerts to one or more workers operating on or near the track, based on communication of the UWB signals with at least one of the one or more wayside units.

Abstract: Systems and methods are provided for platform intrusion detection. An ultra-wideband (UWB) based platform intrusion detection may include transmitting UWB signals into an area in proximity to a platform, the area that includes one or more tracks; receiving UWB signals within the area; and processing received UWB signals to enable detecting objects within the area. The processing may include identifying received UWB signals corresponding to echoes of the transmitted UWB signal transmitted by the detection devices; detecting based on the echoes of the transmitted UWB signals when an object is present within the area; and assessing the object, wherein assessing the object includes determining when the object represents an intrusion within the area.
