When in lockdown mode, all doors, vents and other acesses are automatically closed and sealed off. Lockdown mode was origionally designed to prevent a disastrous chain decompression, but is also employed to block the spread of toxic fumes and fires. While it is usually triggered by the main computer during a crisis, it may be manually activated from any operations station. Once in lockdown mode, doors may still be opened using an override switch. Lockdown mode may be cancelled from the Captain's compartment, Security station, or Engineering station, though is is officially the Security station that encacts the order to stand down from lockdown.
Emergency engine shutdown. Very quick, but hard on the engine. After a scram the engine must be reset. During a scram, the flow of Walterium fuel to the reaction chamber is cut off, isolating the reaction mass. The rear section of the chamber is then "Shocked" with a larger than normal load of electricity. The walterium reacts, the resulting explosion ejecting the rest of the reaction mass out into space.
Walterium engines are used in almost all ships of the time. As a fuel, Walterium is Nonradioactive, cohesive, relatively cheap, and almost completely inert under normal conditions. It is only in a vacuum that it takes on the properties that make it so useful. In a completely unexpected reaction, running an electric current through a concentration of Walterium in a vacuum produces a powerful burst of energy. When this is focused through a magnetic nozzle, a sizeable amount of thrust is produced. Changing the amount of Walterium entering the reaction chamber regulates thrust. While The Walterium is not consumed particularly fast during the reaction, on long haul space flights of four years or more, a lot of fuel is needed. This requirement instigated the use to huge containment chambers, up to the point that ships are designed and built around them. Despite these drawbacks, the Walterium engine is ideal for space travel, mostly due to it's simplicity.
Digipads are employed in much the same role as modern day Clipboards. They are used for the storage and display of information. Cheap and rudimentary computers, they contain around 20 megs of storage space, and the aproximate computing power of a modern pentium 90 mhz processor. Their cost in modern terms would be around $20. Their 9"x 8" x 1" dimentions and light weight make them handy and popular, especially among starship crews.
