Abstract: Systems and method for operating a train are described herein. The train may include a plurality of nodes configured to detect a plurality of train variables and a train controller. The train controller including a memory storing computer-executable instructions; and a processor. The processor may be configured to receive a train model which may be configured to be used by a computation engine of the train controller to generate an output. The output may be displayed on an output device on the train controller. A human-user may input an indication into the train controller indicating that the generated output may be insufficient. The node data may be collected at a result of the input and transmitted to a train model generator.

Abstract: A coloring kit is disclosed which includes writing instruments for making marks in color, a storage container for the writing instruments, and a compact disc that has instructions for reproducing displays of interactive activities utilizing the writing instruments from a personal computer. The interactive activities may include a coloring book or similar such activities. The end user or customer may print physical copies of the displays from a personal computer coupled to a printer. In some embodiments, the storage container may also enclose and store the compact disc.

Abstract: The present invention provides a virtually spill-proof container for use with paint or liquids of comparable viscosity. In particular, the container of the present invention comprises a receptacle having a base portion and a top portion, an insert member with a generally central aperture attached to the top portion of the receptacle, and a barrier member having a hole formed therethrough operatively connected to the insert member. The hole in the barrier member permits a user to access the liquid within the container with a brush or like instrument, while the barrier member functions like an obstruction which prevents, or minimizes, spillage should the container be tipped over or inverted. The barrier member may alternatively be constructed of an absorbent sponge or solid plastic material. A lid is also provided so that the user may conveniently open and reseal the container.
