Abstract: One embodiment of an event management system, operating on a computer system having event producers and event consumers, includes an initial event handler program and an event queue having a first event. The initial event handler program retrieves the first event from the event queue for event processing. This event processing returns a first response to the initial event handler program, wherein the initial event handler program manages the first event on the event queue based on the first response.

Abstract: A window tracking analog to digital convertor (10) and method of signal conversion is disclosed. A sample and hold amplifier (16) samples an analog input signal and passes the sampled signal to a window comparator (20). The window comparator (20) analyzes the analog input signal to determine if its amplitude falls between upper and lower reference levels which establish a tracking "window." If the amplitude of the signal falls outside of the window, a control processor (34) and window reference tracker (24) adjusts the reference levels in the direction of the reference level which was exceeded until the analog input signal falls within the window, the adjusted reference level in the direction of adjustment representing the level of the sampled signal. A continuous interval timer (38) counts the amount of time that the analog input signal remained within the window.
