Abstract: The present invention is a fire control system. The fire control system comprises a manually aimed gun having a sighting device and a device for acquiring a target. The acquiring device is disposed at a location remote from the gun. The fire control system also comprises a device for determining the trajectory of the target with respect to the gun and providing information relating to the target to the sighting device of the gun such that an operator of the gun can aim the gun with respect to the sighting device to hit the target when the gun is fired. The determining device is in communication with the acquiring device and the sighting device. The present invention is also a fire control method for a minor caliber gun. The method comprises the step of acquiring a target from a location which is remote from the gun. Then, there is the step of determining the trajectory of the target with respect to the gun.

Abstract: The invention provides for a cab signaling apparatus and method for use on board a railway vehicle propelled on a set of spaced rails by a traction motor. The cab signaling apparatus may reduce a noise component within a signal having a primary cab signal component and reduce a cab signal component within a signal having a primary noise component. The cab signaling apparatus may further include an adaptive filter to cancel the noise component within the signal having a primary cab signal component without specialized tuning of the cab signaling apparatus. The cab signaling apparatus may include a false code monitor for identifying a true cab signal code and a track signal monitor for identifying a true cab signal in the presence of noise.

Abstract: A railway car retarder mechanism that employs linear electromagnetic induction to precisely accelerate or decelerate a railcar. The retarder mechanism includes a plurality of linear induction stators having a spaced plurality of primary inductors, a controllable power source electrically connected with selected ones of the primary inductors, a controller for controlling the electric current transmitted to the respective primary inductors by the controllable power source, and a sensor for sensing selected railcar parameters and transmitting those parameters to the controller, so that the speed-corrective forces applied by the retarder are proportional to these parameters. The controller regulates the magnetomotive force which is imparted upon a selected one of a plurality of railcar wheel sets, and is connected with each controllable power source. In some embodiments, the sensor include at least a portion of fiber-optic cable, which cable can be disposed proximate to a predetermined length of track rail.

Abstract: A method for selecting and responding to a malicious fault in a reconfigurable electronic apparatus that can perform multiple tasks, and that has fault processing for counteracting a class of faults which can generally cause the apparatus to fail during the execution of a preselected task if the fault processor is unavailable and to which class the malicious fault can belong. The reconfigurable electronic apparatus can be a fault processing system, which can be an interlocking control circuit, or a combinational circuit.

Abstract: A linear induction rail switch mechanism having at least one linear induction motor (LIM) for transversely thrusting a switch track from a first position to a second position. To reduce the frictional forces during transverse movement, the switch mechanism can be levitated from the underlying structures. The switch can have at least one controllable power supply which may supply electric power to an individual LIM or groups of LIMs, which may be three-phase motors. The switch may include a vital controller which is connected to at least one controllable power supply. The vital controller responds to at least one of a feedback signal from a controllable power supply, a feedback signal from a LIM, a feedback signal from a switch track, and a remote signal. The LIM may include a primary inductor which is affixed substantially rigidly to the ground and a secondary which is affixed to the switch track. In some embodiments, the secondary may be a ladder secondary.

The acquiring device is disposed at a location remote from the gun. The fire control system also comprises a device for providing information relating to the target to the sighting device of the gun such that an operator of the gun can aim the gun with respect to the sighting device. The providing device is in communication with the acquiring device and the sighting device. The present invention is also a fire control method for a minor caliber gun. The method comprises the step of acquiring a target from a location which is remote from the gun. Next, there is the step of providing information relating to the target to a sighting device of the gun. Then, there is the step of manually aiming the gun in accordance with the information appearing on the sighting device.

Abstract: A railway traffic control system in which accurate vehicle information is effectively available in real-time to facilitate control of traffic flow. Unlike prior art methods of precisely monitoring train location, the current invention is dependant only on equipment on-board the vehicle and position updates provided by external benchmarks located along the track route. The system's dynamic motion capabilities can also be used to sense and store track rail signatures, as a function of rail distance, which can be routinely analyzed to assist in determining rail and road-bed conditions for preventative maintenance purposes. In presently preferred embodiments, the on-board vehicle information detection equipment comprises an inertial measurement unit providing dynamic vehicle motion information to a position processor.
