  • Patent number: 9071352
    Abstract: A novel free space optics transceiver is disclosed comprising at least one light source, at least one photodetector, corresponding positioning means that can independently adjust the position of the light source and the photodetector, and a controller that can send and receive alignment frames conforming to a communications protocol to and from a remote optical transceiver and can use information in the incoming alignment frames from the remote optical transceiver to appropriately adjust the position of the light source and the photodetector thereby maximizing the received power of light signals sent by the remote optical transceiver. Also, an alignment method is disclosed wherein the controller continuously adjusts the positions of the light source and the photodetector until a light signal is acquired from a remote optical transceiver. Then, the incoming alignment information is used to adjust the light source position to achieve bi-directional communication with the remote optical transceiver.

  • Patent number: 4658730
    Abstract: Apparatus for continuously surveying and aligning railroad track has a measuring system with a leading point and a trailing point, both points being on the track center line. Two tensioned wires extend between these points, respectively, and a common intermediate point also on the track center line. At the trailing point a shadow board is located and this is arranged to interrupt an infrared beam extending between a projector at the leading point and a receiver behind the trailing point. A device measures continuously the angle between the two wires and this value is averaged and then subjected to mathematical manipulation in a computing device to derive an ordinate value for the shadow board which is automatically extended accordingly. The receiver then commands a track correction ram located adjacent the shadow board to move the track radially inwardly or outwardly until alignment between projector, receiver and shadow board causes the receiver to stop the lining action.

  • Patent number: 4367681
    Abstract: An improved technique for correcting errors in track, for example errors in alignment and cross-level. A record of the actual geometric condition of a section of track is obtained by running a recording car operating at a predetermined speed and axle loading over the track. A record which may be on magnetic tape is thus obtained for one or more parameters such as alignment. In some cases this record may be used directly to derive electrical error signals which control a track moving device which moves the track in a direction to remove the error. Where the parameter of interest is alignment and the section of track is curved, a desired geometric condition has to be obtained for comparison with the actual geometric condition to derive the electrical error signals. One way of obtaining the desired geometric condition is to process the record to achieve a running average taken over ten or so consecutive sample points.
