Abstract: To transmit data packets between a transmitter and a receiver, the data packets are transmitted in coded from as coding units. The received data packets are stored in coded or uncoded form in the receiver inside a memory. The receiver notifies the transmitter of the capacity utilization of the memory.

Abstract: A locomotive is provided that includes: a receiver operable to receiving a locating signal, the locating signal indicating a current spatial location of a selected locomotive and a processor operable to (a) determine that the selected locomotive has entered, is entering, and/or is about to enter a spatial zone having at least one controlled parameter, the controlled parameter being at least one of a fuel combustion emissions level and a noise level and (b) configure the operation of the selected locomotive to comply with the controlled parameter.

Abstract: The present invention is directed to a power control architecture for a vehicle, particularly a locomotive, in which a number of energy sources are connected to a common electrical bus and selectively provide energy to the bus based on the relationship between their respective output voltages and the bus voltage.

Abstract: The present invention is directed to a locomotive comprising energy storage units, such as batteries, a prime energy source, such as a diesel engine, and an energy conversion device, such as a generator. The locomotive comprises one or more of the following features: a separate chopper circuit for each traction motor; energy storage units that can be switched from parallel to series electrical connections, an fluid-activated anti-lock brake system, a controller operable to control separately and independently each axle/traction motor, and a controller operable to control automatically a speed of the locomotive. The present invention includes an integrated system for monitoring, controlling and optimizing an electrically powered locomotive using a combination of sensors and software to provide feedback that optimizes power train efficiency and individual drive axle performance for a locomotive that utilizes one of several possible electrical energy storage systems to provide the tractive power.

Abstract: The present invention is directed to the termination of the occurrence of wheel slip/skid and prediction and prevention of the onset of wheel slip/skid in a locomotive. In one configuration, a lookup table of adhesion factors is used to predict the occurrence of wheel slip/skid.

Abstract: A method transmits data packets in a mobile radio system and corresponding mobile radio system. The method permits an immediate transmission of data packets to the receiver station along a new transmission path, after a handover of a connection along a transmission path, between a transmission station and a receiver station, to a new transmitting station. The new transmission station thus receives no information regarding the transmission status of data packets, which were transmitted before the handover of the connection.

Abstract: A control system for individually controlling power from a single voltage source to a plurality of motors is described. A chopper circuit, in conjunction with the control system, generates drive-pulses, which operates the IGBT switching devices to sequentially provide pulses to each motor.

Abstract: The invention relates to a method and a radio communication system for the transmission of packet data units (SN#10, SN#11), by means of a radio interface in a radio communication system with at least one transmitter and at least one receiver, whereby the original data to be sent may be encoded with various codes to give various encoded units (CW1, CW2, CW3). Said various encoded units (CW1, CW2, CW3) are transmitted either consecutively or parallel to increase the redundancy in the receiver-side reconstruction of the original sent data and information on the underlying packet data units (SN#10, SN#11) is transmitted with the encoded units. According to the invention, the reconstruction of data may be expedited and improved by the transmission of information about the corresponding codes (CW1, Cw2, CW3) to the receiver with the encoded units and by a request from the receiver to the transmitter for the transmission of one or several selected encoded units.

Abstract: In a packet data transmission via a radio interface of a communication system, a packet number as identification information is transmitted for every data packet between data stations communicating with one another. To improve transmission security for the identification information, the identification information is multiplied and distributed separately to at least two data packets or transmitted separately in a separate information data packet.

Abstract: Prior battery-powered electric locomotives have used multiple diesel engines to charge the batteries and have not been commercially accepted. The present invention provides a yard switcher which combines battery storage with a gas microturbine generator to provide an effective fuel-efficient and environmentally friendly locomotive. locomotive.
