Abstract: System including an effort-monitoring system configured to control tractive efforts (TEs) individually produced by propulsion-generating vehicles in a vehicle system. The effort-monitoring system is configured to control each of the propulsion-generating vehicles to provide a respective prescribed TE. The vehicle system operates at a system TE when each of the propulsion-generating vehicles is providing the respective prescribed TE. The prescribed TEs are determined by at least one of an operating plan of the vehicle system or a regulation that limits TE or ground speed of the vehicle system. In response to determining that a first propulsion-generating vehicle is providing a reduced TE that is less than the prescribed TE of the first propulsion-generating vehicle, the effort-monitoring system is configured to control a second propulsion-generating vehicle to exceed the prescribed TE of the second propulsion-generating vehicle so that the vehicle system is operating at or below the system TE.

Application number: 20140361780
Abstract: A control module coupled to a switching device that is switchable between an open state and a closed state as part of a switching event is provided. The control module includes a communication interface configured to issue a control signal to the switching device that triggers the switching device to switch between the open state and the closed state, and receive a feedback signal from the switching device indicating that the switching device has switched between the open state and the closed state. The control module further includes a processing device coupled to the communication interface and configured to calculate a characteristic time interval associated with the switching event, wherein the characteristic time interval is indicative of a mechanical switching time of the switching device, and a memory device coupled to the processing device and configured to store the calculated characteristic time interval.

Abstract: Wind turbine systems and methods for operating wind turbine systems are provided. In one embodiment, a method includes gating on a dynamic brake switch of a dynamic brake in a wind turbine power converter when an experienced direct current (DC) bus voltage is equal to or greater than a threshold DC bus voltage. The method further includes disabling a threshold temperature rating for the dynamic brake switch when the dynamic brake switch is gated on, and gating off the dynamic brake switch when the experienced DC bus voltage is less than the threshold DC bus voltage.

Abstract: A method includes operating a vehicle traveling in a transportation network with a throttle of the vehicle at a maximum throttle setting during a trip of the vehicle along a route from a first location to a different, second location. The method also includes applying a dynamic brake of the vehicle at a maximum brake setting of the dynamic brake, and alternating between operating the vehicle with the throttle at the maximum throttle setting and applying the dynamic brake of the vehicle at the maximum brake setting along a route being traveled by the vehicle from the first location to the second location.

Abstract: An insertion target point setting apparatus is provided. The insertion target point setting apparatus includes a reference point setting unit configured to set, in coordinates formed in a three-dimensional space with a subject with a biopsy needle inserted therein, a first reference point which is an insertion target point of the biopsy needle in the subject, and a second reference point which is a noticed portion indication point indicative of a noticed portion in the subject, and an insertion target point setting unit configured to set other insertion target points other than the first reference point in the coordinates formed in the three-dimensional space based on the first reference point and the second reference point, using a predetermined drawing method.
