Grav-plating

One of the (and by far the most prolific) examples of simplistic pretech technologies that was designed with mass production in mind. Grav-plating, also referred to as artificial gravity, is actually a series of interconnected technologies rather than just one. For the sake of brevity we will only touch on the two unique technologies in the suite, excluding those more common apparatus seen in other devices.
The majority of the work is done by the gravimetric core located somewhere near the power core of nearly every starship int he galaxy. This device uses meta-dimensional escape particles from the spike drive to warp space time within it's housing. This is incredibly dangerous technology, and it is kept within a tungsten shell to protect the rest of the ship. Most novice spacers fear the dreaded reactor core breach, and while those events are deadly to a ship and her crew, a gravimetric cored breach is a much worse fate. Should a breach occur, the ship would effectively become a micro-black hole and the crew would instantly be spaghettified over a period of horribly painful milliseconds.
The other technology that makes artificial gravity possible is gravitic-plating. This is a specialized circuitry network laid into the underside of a starship's deck plates and is designed to channel the gravimetric energy created by the warped spacetime inside the gravimetric core. Using this energy, the grav-plating creates a gravimetric field around and throughout the ship, simulating any level of gravity desired. While the grav-plating is all networked together, it can be segmented to allow certain compartments to experience more or less gravity.
Grav-plating is incredibly taxing on the power supply of the ship, and often the gravity experienced on the ship is lessened to .7 gs or lower to conserve power. During Starship Combat grav-plating is often deactivated entirely to allow the full force of the power core to be allocated to combat maneuvers, weapon and defense systems.
