Title: Method and mechanism for reduction of within-train reported data

Granted: 2005-08-02
Abstract: A tracking system for railcars is configured as a dynamic local area network having a master tracking unit and a plurality of slave tracking units, each tracking unit being affixed to a separate railcar. To improve reliability of communications between railcars, the distance from a master unit to a slave unit is estimated by comparing phase of a transmitted signal with that of the transmitted signal returned by another tracking unit in the network.    Optionally, a determination is made as to whether the slave unit is "ahead" of or "behind" the master unit. Communication path loss between the master and slave units due to frequency selective fading may also be determined. A spectrum survey determines quality of the channel as to its capacity for passing data from the slave unit to the master unit.

Title: Improved correlation processing for motion estimation
Inventor: BORER TIMOTHY JOHN
IPC: G06T7/20
Filed: 1996-07-09
Granted: 2003-04-01
Abstract: Motion correlation is a way of analysing movement in image sequences such as  television signals. The estimation of movement in television pictures is essential to enable the use of motion compensated processing techniques. The se techniques yield improved quality video processing and moving image compression. Motion correlation would be used as part of a video motion estimation system. This invention describes a number of enhancements to, and  a simplfied, efficient implementation of, the basic motion correlation algorithm. It is shown how to produce motion correlation surfaces co-timed with output, rather than input, pictures. It is also shown how to average power spectra to obtain improved noise performance, and hence improved accuracy, in motion correlation. Finally it is shown that separate correlati on surfaces can be produced relating to 'future' and 'past' pictures.
