The phase of a voltage controlled oscillator (VCO) can be controlled and changed by a series of pulses applied through an isolating element such as a capacitor. A small amount of current injected into the reactive element distorts the waveform of the VCO during the period of injection. Depending on the power of the pulse of injected current, a corresponding phase shift in the output of the VCO will result during the period of injection. The pulses are applied at a frequency equivalent to the desired frequency. Assuming the waveform of the VCO to be sinusoidal or otherwise symmetrical, the injected current pulses result in one point on the waveform where the distortion will be symmetrical and stable. The injection of repeated pulses results in this stable point eventually occurring symmetrically about the peak of the VCO waveform thereby locking the phase of the VCO to correspond to the frequency of the injected pulses.

A flexible tooling system includes a support table with multiple openings adapted to removably accept a self-contained actuator. Each opening of the support table provides vacuum and air supply lines as well as a bus interface so that each position may be uniquely addressed and commanded separately from any other openings. The self-contained actuator has corresponding connectors for receiving the vacuum and air supply as well as for interfacing with the bus. An actuator may be placed at a particular location by insertion into the receptacle at the opening in the support table aperture. The actuator may be commanded to raise, lower, lock in position and supply vacuum separate from any other actuator.
