Patent number: 11467191Abstract: A circuit for controlling an input current, the circuit includes a first input port configured to receive the input current. A current detector detects an input current value of the input current and generates a control signal indicative of the input current value. A first output port outputs an output current to a load. A second output port receives the output current from the load. A control circuit provides a low-impedance path in parallel with the load in response to the control signal indicating the input current value is below a threshold value.Type: GrantFiled: September 10, 2019Date of Patent: October 11, 2022Assignee: THALES CANADA INCInventors: Abe Kanner, Serge Kniazev, Peter Spasopoulos, Carl Schwellnus

Patent number: 9469318Abstract: A system and method provide the capability to dynamically measure the diameter of a train wheel. An onboard sensor signals detection and loss of detection of a proximity plate having a predetermined length and placed along a direction of travel of the train. A signal generator generates a signal indicating the number of revolutions of the wheel. Based on the sensor signals indicating detection and loss of detection of the proximity plate, the length of the proximity plate, and the corresponding number of wheel revolutions, a controller automatically calculates the wheel diameter.Type: GrantFiled: November 12, 2013Date of Patent: October 18, 2016Assignee: Thales Canada IncInventors: Abe Kanner, Walter Kinio, Ernest Sue

Patent number: 9128841Abstract: A system and method provide vital shutdown of a remote slave unit linked by a fiber optic connection to a local, checked redundant master unit with two paired computers. Each computer sends a life signal to an associated local vital supervision card (VSC) and copper to fiber converter (C/F converter) for transmission via fiber to a corresponding fiber to copper converter (F/C converter) on the slave unit, then to a corresponding remote VSC. Each local VSC controls power to a corresponding second local VSC-associated C/F converter, and each remote VSC controls power to a corresponding second remote VSC F/C converter. A VSC detecting an incorrect life signal signature removes power to the corresponding controlled converter and, optionally, to a respective local or remote I/O rack, thereby shutting down the slave unit.Type: GrantFiled: November 12, 2013Date of Patent: September 8, 2015Assignee: Thales Canada Inc.Inventors: Cameron Fraser, Abe Kanner, Serge Kniazev

Patent number: 9128815Abstract: A control system for a vehicle in a guideway network including a centralized control system configured to generate a first set of instructions. The control system further includes at least one de-centralized control system configured to generate a second set of instructions. The control system further includes an on-board controller configured to receive the first set of instructions and the second set of instructions during a same time period. The on-board controller is configured to receive the first set of instructions using a first communication technique. The on-board controller is configured to receive the second set of instructions via a second communication technique diverse from the first communication technique. If a discrepancy exists, the on-board controller is configured to execute a least restrictive of the first or second set of instructions. The control system is capable of seamlessly transferring control between the two control systems.Type: GrantFiled: January 14, 2013Date of Patent: September 8, 2015Assignee: Thales Canada IncInventors: Abe Kanner, Norman Chong

Patent number: 9096245Abstract: Disclosed is a method of controlling a load in a railway signaling system, the method comprising providing a first autonomous controller connectable to the load and a second autonomous controller which is redundant with the first controller such that there is no single point of failure; operating the first and second controllers in one of two modes. There is an on-line mode wherein both controllers provide power to the load to control the load such that current through the load is shared between the first and second controllers. There is an off-line mode wherein a single controller does not provide power to the load and the other controller continues to operate on-line to control the load, whereby control of the load is uninterrupted.Type: GrantFiled: January 23, 2014Date of Patent: August 4, 2015Assignee: Thales Canada Inc.Inventors: Virgil Lostun, Abe Kanner, Sergio Mammoliti, Cameron Fraser

Patent number: 9085310Abstract: A method of determining the position of a vehicle moving along a guideway is disclosed wherein signals from groups of transponders located beside the guideway are detected as the vehicle moves along the guideway to create a footprint in the time domain corresponding to the time the vehicle is in communication with that transponder. The transponders of each group are spaced a known distance apart from each other. An estimate of the position of the moving vehicle is computed by matching the point in the time domain that bears the same geometric relationship to the footprints corresponding to the transponders of the group to a point in the spatial domain that bears a known geometric relationship with the transponders of each group.Type: GrantFiled: May 25, 2011Date of Patent: July 21, 2015Assignee: THALES CANADA INC.Inventors: Boyd McKillican, Abe Kanner
