Abstract: A safety communication scheme for a safety-critical system which includes two or more higher level units that have voting capabilities and one or two sets of lower level units that do not have voting capabilities, involves using one channel between the high and low level units for safety and two channels for redundancy.

Abstract: A method of determining a position of a vehicle on a guideway includes detecting a position of the vehicle relative to a first reflective positioning element along the guideway. The method also includes detecting a unique identification code of a transponder along the guideway, wherein the transponder is located a first known distance along the guideway from the first reflective positioning element. The method further includes determining the position of the vehicle, using a position determining system, based on a modulated reflection signal received from the transponder, a first non-modulated reflection signal received from the first reflective positioning element, and the first known distance.

Abstract: 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.

Abstract: A position determining system for a vehicle on a guideway which includes an on-board controller configured to determine a position of the vehicle on the guideway. The position determining system further includes a transmitter/detector array configured to emit an interrogation signal and to receive reflection signals based on the emitted interrogation signal. The transmitter/detector array includes a first antenna and a second antenna, the second antenna spaced from the first antenna in a direction of travel of the vehicle. The position determining system further includes a transponder identification database configured to store transponder information. The on-board controller is configured to determine the position of the vehicle along the guideway based on a modulated reflection signal received by the transmitter/detector array and a first non-modulated reflection signal received by the transmitter/detector array.
