摘要:
In one embodiment, a clock generation system comprises first and second hot-swappable oscillator (HSO) devices that generate respective timing signals, a plurality of controllable attenuators for controllably attenuating one of the timing signals, a combiner for combining the timing signals, a redundant clock source (RCS) device for generating at least one clock for distribution to other circuits using an output of the combiner, and logic for switching which of the timing signals is attenuated in response to failure of one of the first and second HSO devices.

Disclosed is a disposable protective garment adapted to stretchably conform to the body of a wearer, the garment being composed of at least one piece of a reversibly-necked material which is adapted to have recoverable stretch in at least one direction. The reversibly-necked material is necked by drawing and treated to impart memory of its necked configuration so it has recoverable stretch while also being breathable, liquid resistant and conformable. The disposable protective garment may contain a body portion, sleeve portions and/or leg portions. The stretch direction of reversibly-necked material may be parallel to the direction of motion of the body portion, sleeve portions and/or leg portions.
