US Patent:

53740157, Dec 20, 1994

Filed:

Sep 16, 1993

Appl. No.:

8/122912

Inventors:

Angel P. Bezos - Rockville MD
Clive Wright - Germantown MD
Emilio A. Fernandez - McLean VA

Assignee:

Pulse Electronics, Inc. - Rockville MD

International Classification:

B61L 2302

US Classification:

246169R

Abstract:

Improvements relating to railroad telemetry and control system address problems in compatibility between HOT and EOT units, implement an automatic UDE location procedure, and automate calibration of EOT units. An improved two way protocol that allows EOT units having different code formats to be used with a HOT unit. A method is implemented by a HOT unit, cooperating with an EOT unit, for locating a fault which causes a UDE brake operation. An automatic calibration procedure for the EOT unit that does not require the operator to have access to the electronic circuitry.
