Abstract: A control circuit which allows computer systems to modify signal timing relationships in the hardware via programmable ports in the system, thereby allowing timing adjustments to be made without effecting motherboard hardware. The control circuit includes a plurality of delay devices configured to provide a plurality of delays under program control. The control circuit is adapted to extend the duration of a write signal to enable data to be latched, normally on the trailing edge of the write signal to avoid latching invalid data.

Abstract: A new method is described that allows determination of the degree of molecular dissociation based on continuous, radio frequency (rf) and microwave driven discharges based on electrostatic probe and emission spectroscopy measurements only. Using this method costly laser-induced fluorescence spectroscopy (LIF) can be avoided. The method described is particularly applicable to hydrogen plasmas characterized by non-thermal electron energy distribution functions which are of great practical importance. A compact combined fiber optic/electrostatic probe facilitating the required measurements is described.
