Abstract:
An aircraft laser system in which a laser beam is generated in one location (e.g. the fuselage) and transmitted via a relay mirror through a window externally of the aircraft structure to a receiver window at another location (e.g. a wing-tip pod). At the receiver, the laser beam passes through the window and is directed by relay mirrors to a turret, the turret receiving and directing the laser beam to an external target.
Abstract:
A method for vehicle control comprises determining a braking capability of a braking system of a rail vehicle or other vehicle, and modifying application of at least one mission parameter by a control system of the vehicle based on the determined braking capability. Braking capability may be determined by activating the braking system of the vehicle to apply a braking force on the vehicle, and concurrently, applying a level of tractive effort of the vehicle is sufficient to overcome the braking force. The braking capability is determined based on the level of tractive effort.
Abstract:
A method for automatically controlling braking of a powered system or consist includes automatically applying a first degree of braking to a consist during a first time period when a powered unit of the consist is being locally or remotely controlled via an onboard control system in an absence of control inputs from an onboard operator. The first degree of braking is based on a first deceleration force selected so that the consist is slowed in a manner effective to limit a peak deceleration rate experienced by the consist sufficient for reducing unintended movement of at least one of one or more riders or cargo onboard the consist. The method also includes automatically applying a second degree of braking to the consist during a second time period following the first time period.

Abstract:
A method of identifying an anomalous orientation definition condition of a remote locomotive (12) of a train includes monitoring an operating condition of the remote locomotive of the train, the remote locomotive configured to operate according to a defined orientation with respect to a lead locomotive of the train. The method also includes identifying an operating condition of the remote locomotive indicative of the remote locomotive operating contrary to an operating condition of the lead locomotive.
Abstract:
A system (10) and method for automatically controlling braking of a train (38). The method includes applying a first degree of braking to the train during a first period of time, and then applying a second degree of braking to the train during a second time period following the first time period so that the train is slowed in a manner effective to limit a peak deceleration rate experienced by the train. The system includes a sensor (36) providing a signal indicative of an operating condition of a locomotive of the train requiring braking of the train, a memory (22) storing a braking schedule, and a processor (18) comprising logic executable for accessing the braking schedule stored in the memory responsive to the signal to automatically control braking of the locomotive according to the schedule.
Abstract:
A system for verifying validity of a pressure reading from a transducer on a remote powered system, the system including a comparator subsystem configured to evaluate a pressure reading differential taken between a first transducer that is part of a braking system on a lead powered system and a second transducer that is a part of a braking system on a remote powered system, wherein the pressure reading differential is taken when the lead powered system and the remote powered system are operating in a distributed power application. A method and computer software code, stored on a computer readable media and executable with a processor, are also disclosed for verifying validity of a pressure reading from a transducer on a remote powered system.
Abstract:
A brake control system for a distributed power vehicle system includes a brake system and a distributed power control system in a first vehicle, and first and second separate communication links between the brake system and the distributed power control system. In operation, upon the initiation of a penalty brake application, the brake system transmits information about the brake level of the penalty brake application to the distributed power control system, over at least the first communication link. However, if the first communication link fails, the brake system redundantly transmits the information about the level of the penalty brake application to the distributed power control system over the second communication link. The information is transmitted from the distributed power control system in the first vehicle to remote vehicles for carrying out the penalty brake application.
Abstract:
A railroad distributed power communication method and system for wireless transceiver units at spaced locations along a train having remote units that may be out of direct communication with the lead unit for indicating that at least one of a plurality of such remote units is in receipt of a command message from the lead unit. The method and system including transmitting a status reply message from each of the plurality of remote units in response to that unit's receipt of the command message. Each of the status reply messages may include at least status information of the respective remote that corresponds to command instructions of the command message. At least one of the status reply messages of one of the other respective remote units may be received at an intermediate unit. The received status reply messages may be compared to the command message to determine whether the respective remote unit has received the command message and/or is following the set of command instructions. A command received status bit may be set in a second status reply message for each respective remote unit having received the command message and/or that is following the set of command instructions. The second status reply message may be decoded by a lead unit to determine whether the command received status bit has been set for a respective remote unit.
Abstract:
A cushion strap assembly and method of making same is provided which cushion strap assembly is adapted to be used in a brassiere shoulder strap. The assembly includes a top fabric layer, a first adhesive web layer positioned on one side of the top fabric layer, and a base layer positioned on the first adhesive layer on the side opposite that of the top fabric layer. The assembly also includes a cushion filler that is a first cushion layer, a third adhesive web layer positioned on a side of the first cushion layer, a second cushion layer positioned on the third adhesive layer on the side opposite that of the first cushion layer. A second adhesive web layer can be part of the cushion filler or separate. In either event, it is positioned on the first cushion layer on the side opposite the third adhesive web layer. The assembly further includes a fourth adhesive web layer positioned on the second cushion layer on the side opposite that of the third adhesive web layer, and a bottom fabric layer positioned on the fourth adhesive web layer on the side opposite that of the second cushion layer.
