Abstract: Maneuverable ergonomic trailer stands are disclosed. An example portable trailer stand includes: a frame having an upper ledge, a post, and a lower subframe, the lower subframe connected to the upper ledge via the post; an extendible leg coupled to the post independent of the lower subframe, the upper ledge being vertically movable based on movement of the extendible leg relative to the upper ledge, the post, and the lower subframe of the frame; and a wheel connected to the frame via the lower subframe such that the wheel is to move with the upper ledge as the upper ledge is vertically moved.

Abstract: Maneuverable ergonomic trailer stands are disclosed. An example portable trailer stand includes a frame having an upper ledge; an extendible leg coupled to the frame, the upper ledge being vertically movable to selectively engage and disengage an underside of a trailer parked on a driveway based on movement of the extendible leg relative to the frame; a wheel connected to the frame, the wheel to remain at a substantially fixed distance from the upper ledge as the upper ledge is vertically moved.

Abstract: Dynamically configurable traffic controllers and methods of using the same are disclosed. An example apparatus includes a first sensor to monitor traffic in a first area. The example apparatus further includes a second sensor to monitor traffic in a second area. The example apparatus also includes a projector to project light toward a floor when traffic is detected in both the first and second areas, the light to be visible from the first and second areas.

Abstract: Dynamically configurable traffic controllers and methods of using the same are disclosed. An example apparatus includes a first sensor to face a first direction to detect oncoming traffic in a first area, a second sensor to face a second direction to detect oncoming traffic in a second area, and a first display to face the first area. The first display is to display a first signal in response to (1) the first sensor not detecting the oncoming traffic in the first area and (2) the second sensor detecting the oncoming traffic in the second area. The first display is to display a second signal in response to (1) the first sensor detecting the oncoming traffic in the first area and (2) the second sensor detecting the oncoming traffic in the second area. The first signal is different than the second signal.

Abstract: Dynamically configurable traffic controllers and methods of using the same are disclosed. An example apparatus includes a first display facing a first direction; a second display facing a second direction; a third display facing a third direction; and a processor, in response to a first input being received indicative of traffic approaching the first display and no traffic approaching the second display and the third display, the processor to cause the second display and the third display to display a first signal and for the first display not to display the first signal or a second signal, the first signal providing a first warning level, the second signal providing a second warning level greater than the first warning level, the first signal illuminatable on the second display, the second signal illuminatable on the second display, the first signal, when illuminated, disposed within a perimeter of the second signal, when illuminated.

Abstract: Motion sensing dock lighting systems are disclosed. An example lighting system for use at a loading dock where a material handling device is used to load or unload a vehicle parked at the loading dock includes a motion sensing system to be spaced apart from the material handling device. The motion sensing system is to provide an operation signal in response to the material handling device undergoing a change in travel direction within the vehicle. The example lighting system also includes a lamp to be operatively connected in signal communication with the motion sensing system so as to receive the operation signal from the motion sensing system. The lamp is to have a first illuminating mode and a second illuminating mode, and the lamp is to switch between the first illuminating mode and the second illuminating mode in response to the operation signal.

Abstract: Disclosed herein are methods for detecting a water leak in a locomotive engine cooling system comprising numerous components, each being a potential source of leakage of water. The method typically comprises performing at least one inspection providing an indication of a water leak from an engine cooling system of the locomotive. The step of performing at least one inspection may comprise at least one of several steps including performing a visual inspection to determine if water is leaking from a portion of the cooling system external to the engine; performing a visual inspection of exhaust of the engine to detect an indication of water vapor in the exhaust; performing a visual inspection to detect an indication of water leaking into an intake air manifold 30 of the engine; performing an engine oil analysis to detect water in the engine lubricant; reviewing a fault log history for the locomotive; and checking a level of a cooling system sight glass.
