Title: Train control system integrating dynamic and fixed data
Inventor: HEGGESTAD ROBERT E
IPC: B61L3/00
Filed: 1993-08-04
Abstract: ABSTRACT OF THE DISCLOSURE           A train control system employs beacon transponders along the track to transmit fixed data to a passing train in addition to dynamic data relating to track availability and routing provided by encoded cab signals transmitted in the track.          The fixed data includes the location of block boundaries and distances to such boundaries, timetable speed limits, and the distance to a point along the track at which a speed restriction is in effect.  This data and other fixed information is integrated with the dynamic data in an on-board computer which determines train control instructions from the received data and displays the instructions to the train crew.  The system is capable of enforcing any restrictive instructions that are not obeyed.

Patent CA-2110002-A1 (CA)
Inventor: SMITH LAWRENCE E
IPC: H04N3/18
Filed: 1993-11-25
Abstract: A first resonant retrace circuit is operable for generating a first voltage signal and a second resonant retrace circuit coupled to the first resonant retrace circuit is operable for generating a second voltage signal summed with the first voltage signal. An auxiliary winding of a flyback transformer in the first resonant retrace circuit generates a first feedback pulse signal representative of the first voltage signal. A regulator senses the summed first and second voltage signals and generates a second feedback pulse signal representative of the summed first and second voltage signals. The second resonant retrace means is responsive to the regulator. A resistive summing junction combines the first and second feedback pulse signals to generate a composite feedback pulse signal. A voltage level is generated indicative of the energy in the composite feedback pulse signal. An overvoltage protection circuit is responsive to the voltage level for disabling operation of at least one of the first and second resonant retrace circuits.

Title: Case mounted readout modification for improved low rate performance
Inventor: THORLAND RODNEY H
IPC: G01C19/66
Filed: 1994-01-04
Abstract: Law rate performance is vastly improved by reducing undesired backscatter sources. Backscatter is eliminated by repositioning some of the backscattered sources to direct any reflected backscatter out of the lasing plane. The case mounted optical elements of a case mounted readout system are positioned such that all of the initial surfaces which are encountered by optical signals are an angle not normal to the optical signal. This positioning causes any reflections off of the aforementioned surfaces to be directed away from the lasing plane that is eliminating the possibility that these reflections will be coupled back into the lasing cavity.
