Abstract: A surgical instrument comprises a body, shaft, and end effector. The shaft couples the end effector and body together. The end effector comprises an anvil and lower jaw configured to receive a surgical staple cartridge. The anvil is configured to pivot toward and away from the staple cartridge and lower jaw. The shaft assembly comprises a knife member configured to longitudinally translate to thereby substantially simultaneously cut clamped tissue and staple the severed tissue. The end effector may comprise lockout features configure to prevent longitudinal translation of the knife member. The end effector or staple cartridge may comprise lockout bypass features configured to prevent lockout of the knife member. These lockout bypass features may operate to permit longitudinal translation of the knife member once or multiple times. The end effector may comprise features configured to ensure proper alignment of the anvil relative to the staple cartridge.

Abstract: A method for cleaning a surface of an aluminum or aluminum alloy body by immersing the surface in a basic aqueous electrolyte formed essentially from dissolved trisodium phosphate, flowing DC current through the electrolyte and the body for cleaning, and then removing the body from the electrolyte. An additional cleaning step, which may include ultrasonic cleaning, may be performed to remove loose matter adhering to the body after the electrolytic cleaning.

Abstract: A method for cleaning a surface of an aluminum or aluminum alloy body of coatings, contaminants, dirt, or the like by immersing the surface in a basic aqueous electrolyte containing carbonate ions, connecting the body directly to the negative terminal of a DC current source and flowing DC current through the body. After a time, the flow of DC current is stopped and the surface is removed from the electrolyte. The surface is then rinsed off to remove the coating, dirt, contaminants, or the like from the surface.

Abstract: A method for cleaning a surface of a metal or metal alloy body by immersing the surface in a basic aqueous electrolyte containing carbonate ions, and flowing DC current through the body to make the body anodic. After a time, the flow of DC current is stopped and the surface is removed from the electrolyte. The surface is then rinsed off to remove dirt, corrosion, coatings, and the like from the surface.

Abstract: An apparatus and method for generating a Contact Glow Plasma Discharge in an electrolyte such as 7% K2CO3. A Shrouded Toroidal Anode is partially submerged in the electrolyte directly above a Flat Torus Cathode (totally submerged in the electrolyte), spaced approximately 50 mm apart, and the two electrodes are arranged in a concentric manner. A potential difference is applied from the cathode to the anode causing gas to be formed on the cathode. This is followed by a contact glow plasma being formed on the surface of the cathode and electromagnetically confined by a Spheromark formed by the configuration of the electrodes. This confinement of the plasma prevents a plasma arc from consuming the anode, which in turn allows for the application of 12,000 Watts and the occurrence of “non-linear electron resonance heating”. The effects of nonlinear series resonance increase the total power dissipation by factors of 2-5 for low pressure capacitive plasmas.

Abstract: The present invention provides for making code rate adjustments and modulation type adjustments in a pseudonoise (PN) encoded CDMA system. Coding rate adjustments may be made by changing the number of information bits per symbol, or Forward Error Code (FEC) coding rate. A forward error correction (FEC) block size is maintained at a constant amount. Therefore, as the number of information bits per symbol are increased, an integer multiple of bits per epoch is always maintained. The scheme permits for a greater flexibility and selection of effective data rates providing information bit rates ranging from, for example, approximately 50 kilobits per second to over 5 mega bits per second (Mbps) in one preferred embodiment.
