  • Publication number: 20200165787
    Abstract: A portable barricade includes a road plate, first and second support posts extending upward from end portions of the road plate, a barricade arm extending between the first and second support posts, and a lift coupled one of the end portions of the barricade arm and a corresponding one of the first and second support posts. Actuation of the lift is configured to slide the barricade arm relative to the first and second support members between a retracted position proximate to the road plate and a deployed position distal from the road plate.

  • Publication number: 20200034637
    Abstract: A system for real-time asset recognition and location includes an image capture and recognition system having a plurality of image capturing devices for capturing image data of an area surrounding a railroad track and a position determination system for determining a position of assets in the area surrounding the track. A processor analyzes captured image data and recognizes assets and correlates a determined position with each recognized asset. The system recognizes assets and determines positions of assets in real-time as the system is transported along a railroad track by a survey vehicle. The captured and analyzed data is stored to a data storage unit for immediate use in updating a railroad asset data base, subdivision files, or positive train control (PTC) files.

  • Publication number: 20190338477
    Abstract: A portable bollard for arresting motion of a vehicle includes a post, a base plate coupled to the post, a top plate coupled to the post and spaced apart from the base plate along a length of the post, and a tapered member extending from a surface of the top plate facing the base plate to the post.

  • Patent number: 6621956
    Abstract: An optical fibre bend sensor (10) measures the degree and orientation of bending present in a sensor length (30) portion of a fibre assembly (26). Within a multicored fibre (30, 32,34), cores (62, 66) are grouped in non-coplanar pairs. An arrangement of optical elements (28, 36, 38) define within each core pair (62, 66) two optical paths (122, 124) which differ along the sensor length (30): one core (62) of a pair (62, 66) is included in the first path (122), and the other core (66) in the second path (124). A general bending of the sensor region (30) will lengthen one core (62, 66) with respect to the other. Interrogation of this length differential by means of interferometry generates interferograms from which the degree of bending in the plane of the core pair is extracted. Bend orientation can be deduced from data extracted from multiple core pairs.

  • Patent number: 6137573
    Abstract: A sensor system (10) incorporating an interferometer operates as an optical strain gauge. The system (10) is arranged to generate interferograms characterised by an optical path difference between light traversing a sensor arm (12) of the interferometer and light traversing a reference arm (58). Each arm incorporates a highly birefringent optical fibre (38, 58) capable of supporting light propagation at two velocities in two different polarisation modes. A first interferogram is generated between light coupled into the fast eigenmodes of each fibre and a second is generated between light coupled into the slow eigenmodes. Mean optical group delay (.tau..sub.MGD) and differential optical group delay (.tau..sub.DGD) of these interferograms are affected differently by temperature and strain and thus provide a means of discriminating between these attributes of the sensor environment. Thus simultaneous measurement of strain and temperature is achieved.

  • Patent number: 5721615
    Abstract: A sensor system in an interferometric arrangement has a sensor arm and a reference arm. The reference arm is in a stable environment and the sensor arm is arranged to be subject to variations in strain and/or temperature. Radiation from a broadband source propagates through the arrangement and a broadband interferogram is generated as an air gap is scanned. The interferogram is recorded on an oscilloscope and analyzed using signal processing software on a computer. From the analysis the changes in group delay and optical dispersion of the light in the sensor arm due to strain and temperature changes is measured, and values for the strain and/or temperature changes calculated. A narrowband light source may be used for accurate calibration of path length differences during scanning. The strain and temperature on the sensor arm may be calibrated or tested using clamps and a thermal enclosure.
