Abstract: Instrument control and data acquisition in advanced analytic systems that utilize optical pulses for sample analysis are described. Clocking signals for data acquisition, data processing, communication, and/or other data handling functionalities can be derived from an on-board pulsed optical source, such as a passively mode-locked laser. The derived clocking signals can operate in combination with one or more clocking signals from a stable oscillator, so that instrument operation and data handling can tolerate interruptions in operation of the pulsed optical source.

Abstract: An exercise machine is provided with a pair of vertically adjustable support posts having a rod extending thereacross. A support plate for receiving the upper back portion of a user is fixedly secured to the rod, while a lower support plate is interconnected with the upper support plate through a universal joint which may be selectively locked into position or released to allow the lower support plate to swivel with respect to the upper plate. An appropriate gear reducer is connected to the rod to allow the rod to be rotated to position the user in a desired orientation.
