The two congruent faces are also commonly referred to as the ends of the prism. The surfaces that connect the two congruent faces are called the lateral faces. In this disclosure, when further description is required a prism will be named for the geometric or descriptive name of the form factor of the two congruent faces. If the form factor of the two corresponding faces has no clearly established or well-known geometric or descriptive name, the term irregular prism will be used. The center axis of a prism is defined as a line that joins the center point of the first congruent face of the prism to the center point of the second corresponding congruent face of the prism. The center axis of a prism is otherwise analogous to the center axis of a cylinder. A prism wherein the ends are circles is commonly referred to as a cylinder.

Relays are further defined with a coil and a switch. Applying a voltage to the coil, usually referred to as energizing the coil, will cause the coil to change the position of the switch. This definition is not intended to preclude the substitution of a transistor for a relay. Within this disclosure, a transistor can be considered as a relay. In this scenario, the base voltage is analogous to the coil of the relay and the current flow from the collector to the emitter is analogous to the operation of the switch of the relay. Those skilled in the electrical arts will recognize that this substitution can be made without undue experimentation. The transistor is defined in greater detail elsewhere in this disclosure.

Transistor: As used in this disclosure, a transistor is a general term for a three-terminal semiconducting electrical device that is used for electrical signal amplification and electrical switching applications. There are several designs of transistors. A common example of a transistor is an NPN transistor that further comprises a collector terminal, an emitter terminal, and a base terminal and which consists of a combination of two rectifying junctions (a diode is an example of a rectifying junction). Current flowing from the collector terminal through the emitter terminal crosses the two rectifier junctions. The amount of the electric current crossing the two rectified junctions is controlled by the amount of electric current that flows through the base terminal. This disclosure assumes the use of an NPN transistor. This assumption is made solely for the purposes of simplicity and clarity of exposition. Those skilled in the electrical arts will recognize that other types of transistors, including but not limited to, field effect transistors and PNP transistors, can be substituted for an NPN transistor without undue experimentation.
Tube: As used in this disclosure, a tube is a hollow prism-shaped device formed with two open ends. The tube is used for transporting liquids and gases. The line that connects the center of the first congruent face of the prism to the center of the second congruent face of the prism is referred to as the center axis of the tube or the centerline of the tube. When two tubes share the same centerline they are said to be aligned. When the centerlines of two tubes are perpendicular to each other, the tubes are said to be perpendicular to each other. In this disclosure, the terms inner dimensions of a tube and outer dimensions of a tube are used as they would be used by those skilled in the plumbing arts.
Vehicle: As used in this disclosure, a vehicle is a device that is used for transporting passengers, goods, or equipment. The term motorized vehicle specifically refers to a vehicle can move under power provided by an electric motor or an internal combustion engine. The term vehicle generically applies to motorized vehicles and vehicles without a motor.

As used in this disclosure, the definition of water is expanded to include dilute water-based solutions of salts and ionic structures using water as the solvent.
