Abstract: A transmitter for remotely controlling a locomotive entity. The transmitter has a control entity capable of acquiring a plurality of states, including a linked state. The transmitter also has an interface in communication with the control entity for receiving an identifier of the locomotive entity via a communication link. The transmitter also has a proximity detector having a detection field, the proximity detector being in communication with the control entity to enable the control entity to switch to the linked state at least when the locomotive entity is in the detection field.

Abstract: A method and system for computing demurrage charges for a private railway site is provided. Information is delivered to a user for prompting him to enter demurrage charge computation parameters. The user enters the demurrage charge computation parameters via a computer interface. In response to the user providing the demurrage charge computation parameters, a database of railcar events is searched based on the demurrage charge computation parameters to derive a set of railcar entries. A charge policy is applied to the set of railcar entries to generate at least one data element indicative of a demurrage charge. The demurrage charge is then displayed to the user.

Abstract: A system of controller modules allowing to remotely control a train having a first locomotive and a second locomotive separated from one another by at least one car is provided. The system of controller modules comprises a first controller module associated to the first locomotive and a second controller module associated to the second locomotive. One of said controller modules has a lead operational status and the other has a trail operational status. The controller module having the lead operational status receives a master control signal for signaling the train to move in a desired direction and releases in response to the master control signal a first local command signal. The first local command signal is operative to cause displacement of the locomotive associated with the controller module having the lead operational status.

Abstract: A remote control system for a locomotive. The remote control system includes a lead controller and follower controller connected to one another over a wireless communication link. The lead controller issues commands over the wireless communication link and those commands are implemented by the follower controller mounted on-board the locomotive. The lead controller is responsive to voice commands uttered by the operator.

Abstract: The invention relates to a method and an apparatus for remotely controlling devices, more particularly to a system and method for controlling locomotives in a railway environment using radio frequency signals. This invention makes use of equalized pseudo-random transmission intervals obtained using a random number generator to regulate the times at which the signals are sent from a transmitter to a receiver. The use of these randomly generated transmission intervals allows eliminating the requirement of having an operator manage these intervals for transmitters in simultaneous operation. The invention also provides communication systems operating concurrently with substantially uniform response times by constraining the values of the transmission intervals to lie within a given range.

Abstract: A portable master controller for a locomotive remote control system. The portable master controller has a user interface for receiving commands to control the movement of the locomotive. The user interface is responsive to operator commands to generate control signals. A processing unit receives the control signals from the user interface to generate digital command signals directing the movement of the locomotive. A transmission unit receives the digital command signals and generates a RF transmission conveying the digital command signals to the slave controller. A solid-state tilt sensor in communication with the processing unit communicates inclination information to the processing unit about the portable master controller. The processing unit receives and processes the inclination information.

Abstract: The invention relates to a method and an apparatus for remotely controlling device, more particularly to a system and method for controlling locomotives in a railway environment using radio frequency signals. This invention makes use of a remote operator programming unit (OPP) to set address information in the transmitter unit via a communication channel such as an infrared link. The use of the operator programming unit allows eliminating the need to open the casing of the transmitter during programming thereby reducing the probability of damaging the electrical components of the transmitter. The invention also allows assigning a unique address to a transmitter/receiver pair in a remote control system. The invention further provides an apparatus for remotely programming a transmitter unit.
