Abstract: A system and method for over-voltage protection is described. In one embodiment of the invention, an apparatus includes an output port configured to deliver power to a plasma chamber to ignite a plasma. The apparatus also includes a shunt switch in parallel with the output port and a processor configured to receive an indicator of an arc in the plasma. The processor is configured to close the shunt switch for a period of time to divert current away from the arc. The processor is also configured to trigger a pulse of the shunt switch to limit a voltage of an increasing voltage condition associated with the arc.

Abstract: A modular vehicle system, for enabling configuration thereof as required. The system includes a core vehicle, and a module, for enabling configuration of the core vehicle as required, able to be integrated into the core vehicle, and able to be disconnected from the core vehicle for interchange thereof with another module.

Abstract: An equipment housing for passive or active electronic equipment includes a back box and a front enclosure that is mounted to the back box via one or more hinges. The housing is suitable for mounting within a wall or against a wall. In one embodiment, the front enclosure includes a front panel and one or more drawers pivotally mounted to permit the stowage of equipment mounted in the drawer within the housing in a first pivotal orientation of the drawer and access to the equipment mounted in the drawer in a second pivotal orientation. In another embodiment, the front enclosure includes at least one frontal portion that is angled with respect to the front panel and extending outward therefrom to form ***. Equipment may be mounted to the frontal portion or a compartment. Acces so as to provide access to the front panel of the equipment. The front enclosure is pivotally mounted to the back box to provide access to equipment within the housing for purposes of wiring during installation, upgrades and service.
