Abstract: A method of denuding bone stock with a denuder, such as a bone stock denuder container, is disclosed. The bone stock is deposited into a wash chamber formed with a curved chamber wall. The bone stock is impacted with a stream of fluid under pressure to separate non-bone tissue from bone. Fluid and non-bone tissue are drained from the wash chamber.

Abstract: A denuder, such as a bone stock denuder container, is disclosed. The denuder includes a nozzle and a container body. The nozzle is configured to be fluidically coupled to a source of fluid and to direct a fluid stream. The container body includes curved chamber wall that forms a wash chamber. The wash chamber is configured to receive a bone stock. The nozzle is configured to direct the fluid stream to impact the curved chamber wall.

Abstract: A system and method for monitoring RF power is described. In one embodiment the system samples RF power that is generated by an RF generator to obtain RF signals that include information indicative of electrical characteristics at a plurality of particular frequencies that fall within a frequency range. The RF signals are digitized to obtain a stream of digital RF signals that include information indicative of electrical characteristics at the plurality of particular frequencies, and the information indicative of electrical characteristics is successively transformed, for each of the plurality of particular frequencies, from a time domain into a frequency domain.

Abstract: A matching circuit is provided for delivering radio frequency electromagnetic energy from a radio frequency power supply to a variable impedance load such as a gas plasma. The matching network couples and impedance matches the power supply to the load. The matching network includes a ratio circuit for establishing a voltage ratio between the power supply and the load and a tuning circuit for tuning out a complex portion of the reactance of the load. Separation and control of the ratio and tuning variables is achieved through provision of a ratio control circuit comprising a lumped quarter wave transformer and a tuning control circuit comprising a variable tuning capacitance and a tuning inductance electrically connected in parallel to the load.
