Abstract: A power generator includes a power source and a control module coupled to the power source. The control module is configured to generate at least one control signal to vary a respective at least one of an output signal from the power source or an impedance between the power source and a load. The output signal includes a signal modulated by a pulse signal, and the control module is further configured to adjust the at least one control signal to vary at least one of an amplitude or a frequency of the output signal or the impedance between the power source and the load to control a shape of the pulse signal. The at least one of the amplitude, the frequency, or the impedance is adjusted in accordance with respective feedforward adjustments that vary in accordance with a respective sensed pulse parameter detected between a matching network and the load.

Abstract: A version control system for managing versioned files comprises a central server storing a repository of the versioned files. At least one proxy is connected to the central server. Each proxy includes a read-only cache for storing data from the repository. At least one client is connected to each of the proxies. Modifications to the versioned files may only be made by the central server.
