- digital control system — (systems) (DCS) A digital computer used for real-time control of a dynamic system, usually in an industrial environment, possibly as part of a Supervisory Control and Data Acquisition (SCADA) system. A DCS samples feedback from the system under control and modifies the control signals in an attempt to achieve some desired behaviour. Analysis of such digital-analogue feedback systems can involve mathematical methods such as difference equations, Laplace transforms, z transfer functions, state space models and state transition matrices.

- field emission display — (hardware) (FED) A type of flat panel display in which field emitting cathodes bombard a phosphor coating causing it to emit light. A field emission display is similar to a cathode ray tube but only a few millimeters thick. They use a large array of fine metal tips or carbon nanotubes (which are the most efficient electron emitters known), to emit electrons through a process known as field emission. Many of these are behind each phosphor dot so FEDs do not display dead pixels like LCDs even if 20% of the emitters fail. Sony is researching FED because it is the flat-panel technology that comes closest to matching the picture of a CRT.
