Method and apparatus for swapping lead and remote locomotives in a distributed power railroad train
InactiveUS20050189815A1Speed controllerElectric signal transmission systemsTransition stageCommunications system
A method and apparatus for swapping functionality of a lead unit and an end-of-train remote unit on a distributed power railroad train. The communications system comprises a swap function that executes through a plurality of process steps to swap the functionality of the lead unit and the end-of-train remote unit. The train operating conditions must first be determined to ensure that the swap function can be executed. The communications system is placed in an idle mode and brakes and safety locks applied to ensure against train movement. Each remote locomotive in the train is commanded to a transition stage and reconfigured to receive commands and messages from the new lead unit. Once the train operator has relocated from the old lead unit to the new lead unit, the old lead unit transitions to remote status and the new lead unit commands an end to the transition period. The train brakes are released and the communications system placed in a normal operational mode, at which time motive power can be supplied for train movement.

A p-type semiconductor zinc oxide (ZnO) film and a process for preparing the film are disclosed. The film is co-doped with phosphorous (P) and lithium (Li). A pulsed laser deposition scheme is described for use in growing the film. Further described is a process of pulsed laser deposition using transparent substrates which includes a pulsed laser source, a substrate that is transparent at the wavelength of the pulsed laser, and a multi-target system. The optical path of the pulsed laser is arranged in such a way that the pulsed laser is incident from the back of the substrate, passes through the substrate, and then focuses on the target. By translating the substrate towards the target, this geometric arrangement enables deposition of small features utilizing the root of the ablation plume, which can exist in a one-dimensional transition stage along the target surface normal, before the angular width of the plume is broadened by three-dimensional adiabatic expansion. This can provide small deposition feature sizes, which can be similar in size to the laser focal spot, and provides a novel method for direct deposition of patterned materials.
