Abstract: In one embodiment, a method includes generating a first visual representation of a location of a railroad station in relation to a railroad track, receiving a request for a first maintenance window, and determining that the first maintenance window is associated with the railroad station. The method further includes determining a first time period and generating a second visual representation of information associated with the railroad station during the first time period. The information includes an indication of a time that a train is scheduled to cross the railroad station during the time period. The information also includes an indication of a time duration for a second maintenance window that has been requested during the time period.

Abstract: An adjustable mount for attaching a sighting device to a firearm includes an elongated base member and an elongated mount member longitudinally slidably engageable with the base member. Either the base member or the mount member includes a plurality of nonparallel longitudinal engagement slots. The other of the base member or the mount member includes a longitudinal engagement tongue which is selectively longitudinally slidably engageable in each of the plurality of slots to selectively position the mount member at different angles relative to the base member. At least one transverse clamping member is configured to secure the base member and mount member against relative longitudinal movement.

Abstract: The multi-purpose balloon catheter comprises a tubular body having a proximal end portion, a distal end portion and at least two lumens within the tubular body. The distal end portion has three spaced apart balloons thereon, the distal balloon being an occlusive balloon, the middle balloon being a stent mounting balloon and the proximal balloon being an occlusive balloon.
