Method For Advanced Communication-Based Vehicle Control

View page
US Patent:
6459965, Oct 1, 2002
Filed:
Jun 18, 2001
Appl. No.:
09/681853
Inventors:
Alan L. Polivka - Palm Bay FL
James R. Egnot - Melbourne FL
Robert E. Heggestad - Odessa MO
Jeffrey K. Baker - Olathe KS
William L. Matheson - Palm Bay FL
Assignee:
GE-Harris Railway Electronics, LLC - Melbourne FL
International Classification:
G06F 700
US Classification:
701 19, 701 20, 701 24, 180168
Abstract:
A method is provided for controlling movement of a plurality of vehicles over a guideway partitioned into a plurality of guideway blocks. The method uses a control system including an onboard computer (OBC) located on board each vehicle, at least one server for communicating with the OBCs, and a vehicle tracking system. The method including the steps of determining a composite block status for all guideway blocks, broadcasting the composite block status to the OBCs, and controlling movement of each vehicle based on the composite block status.

Method For Detecting The Extent Of Clear, Intact Track Near A Railway Vehicle

View page
US Patent:
20130334373, Dec 19, 2013
Filed:
Jun 13, 2013
Appl. No.:
13/916943
Inventors:
Alan L. Polivka - Pueblo West CO, US
International Classification:
B61L 23/04
B61L 27/00
US Classification:
246 2 R, 246121
Abstract:
A method is provided for detecting broken rail, track continuity, and track occupancy ahead of or behind a railroad vehicle traveling in fixed-block territory equipped with an AC track code wayside signal system or cab signal overlay system, and a communications link. This method, when used as an integral part of a communications-based train control (CBTC) or positive train control (PTC) system, allows immediate, automatic detection of broken rail, track occupancies, or open turnouts ahead of or behind a train in an occupied block. It also facilitates true moving-block or virtual block CBTC or PTC, thereby enabling higher efficiency and track utilization.

Automatic Train Control System And Method

View page
US Patent:
58289798, Oct 27, 1998
Filed:
May 15, 1997
Appl. No.:
8/856754
Inventors:
Alan L. Polivka - Palm Bay FL
William L. Matheson - Palm Bay FL
Assignee:
Harris Corporation - Melbourne FL
International Classification:
B61L 300
US Classification:
701117
Abstract:
A system and method for controlling the movement of plural freight trains through a multiple route railway system with improved efficiency and safety. Freight train movements are precisely monitored and orchestrated in accordance with a dynamic schedule that is determined through an evaluation of delivery requirements, coordination among all trains, speed restrictions and the effects of the track topography and train consist on train response to brake and power application.

System For Conducting Video Communications Over Satellite Communication Link With Aircraft Having Physically Compact, Effectively Conformal, Phased Array Antenna

View page
US Patent:
54636566, Oct 31, 1995
Filed:
Oct 29, 1993
Appl. No.:
8/146289
Inventors:
Alan L. Polivka - Palm Bay FL
Charles Zahm - Indialantic FL
Assignee:
Harris Corporation - Melbourne FL
International Classification:
H04N 7167
H04B 169
US Classification:
375200
Abstract:
A system architecture and communication methodology for significantly reducing the size of an aircraft antenna required to provide full broadcast quality video communications with an aircraft via a satellite communications link includes a combination of video bandwidth compression, spread spectrum waveform processing and an electronically steered, circular aperture phased array antenna, that is conformal with an airframe surface of the aircraft. The combination provides sufficient signal power to the aircraft, enables interference from other satellites to be rejected and maintains the power spectral density of the satellite's video transmission within FCC requirements. The polarization of the receive array is aligned with that of the incoming beam from the relay satellite by means of an error signal feed back path to control the steering weights of the array. Because the phased arrays are conformal, it is necessary to modify the phase shift settings produced by the antenna steering mechanism executed by the degree of departure of the conformal geometry of the array from a planar configuration. A coordinate transformation look-up table is coupled in the control feedback path from the antenna steering mechanism and the phase shift elements of the phased array.

Quasi-Moving Block System Of Train Control

View page
US Patent:
20220185350, Jun 16, 2022
Filed:
Dec 15, 2021
Appl. No.:
17/552218
Inventors:
- Pueblo CO, US
Alan Lee Polivka - Pueblo West CO, US
Paulo Roberto Vieira - Pueblo CO, US
Assignee:
Transportation Technology Center, Inc. - Pueblo CO
International Classification:
B61L 27/20
B61L 25/02
B61L 23/34
B61L 1/18
B61L 23/04
Abstract:
A system of train control uses a quasi-moving block methodology for controlling operation of a plurality of trains from a remote office. The office parses the route information for each train into non-overlapping movement authorities that are issued via a communications network. As each train proceeds, it communicates with the office to automatically roll up its movement authority and release the portion of the movement authority behind the train. The office then extends the movement authority of the subsequent train to reflect the released portion of the movement authority of the leading train. The track can be divided into a series of track circuits to enable detection of broken rail or unexpected occupancy. The office segment can then control operation of trains accordingly if broken rail or unexpected occupancy is detected in the train's movement authority.

Method For Detection Of Rail Breaks On Occupied Blocks To Support Reduced Train Spacing

View page
US Patent:
20180327008, Nov 15, 2018
Filed:
Jul 10, 2018
Appl. No.:
16/031863
Inventors:
- Pueblo CO, US
Alan Lee Polivka - Pueblo West CO, US
Joseph David Brosseau - Pueblo CO, US
Assignee:
Transportation Technology Center, Inc. - Pueblo CO
International Classification:
B61L 23/04
B61L 25/02
Abstract:
A method for detecting broken rail and track occupancies measures both the electrical current and voltage on each end of the block of track. This allows a broken rail to be detected even with a shunting axle (occupancy) in the same detection block. The method also provides broken rail detection capability to support modes of operation in which a following train maintains safe spacing from a leading train without the use of track circuit information for train location, allowing for reduced train spacing. The current and voltage measurements are used to make binary decisions, in order to minimize the sensitivity to variations in track impedance characteristics. When combined with train location information, this method also allows for identifying the location of a rail break.
