20110066905 | Test Pin Gating for Dynamic Optimization - An improvement to an integrated circuit of a type having a test enable line for enabling an electrical test of the integrated circuit only when the test enable line is at a logical high value, and output lines that are only used during the electrical test of the integrated circuit, where the improvement is a switch circuit for disabling a state change in the output lines when the test enable line is at a logical low value. In this manner, the output lines do not switch during functional use of the integrated circuit, and cannot be aggressors on the data signals that are carried by the data lines that are used during the functional use of the integrated circuit. In addition, these non-switching output lines can act as guard traces that run between the data lines, further electrically isolating the data lines from one another. Further, because they do not switch during functional use of the integrated circuit, the overall power consumption of the integrated circuit is reduced. | 03-17-2011 |
20110320997 | Delay-Cell Footprint-Compatible Buffers - A method for creating a design for an integrated circuit, by developing a set of delay cells where each of the cells in the set has a different delay time from the other cells in the set, and where each of the cells in the set has the same surface area, has the same pin-outs, has the same drive strength, and has the same input capacitance, where an originally-used cell in the set can be swapped out for a different replacement cell in the set without any impact on the design of the integrated circuit besides a change in delay time from the originally-used cell to the replacement cell. | 12-29-2011 |

20140342918 | Method For Affinity Purification - The disclosure relates to a switchable aptamer having a high affinity for a selected target such as a virus, cell or antibody when in the presence of a binding ion and a low affinity for said target in the absence of said binding ion. The switchable aptamer may be isolated from a pool comprising a mixture of aptamers by incubating the pool with the target ligand and a binding ion to form target-aptamer complexes; separating unbound aptamer molecules from the target-aptamer complexes; contacting the target-aptamer complexes with a chelating agent having affinity for the binding ion wherein a switchable aptamer specific to said target is released from the target-aptamer complexes; and isolating the switchable aptamer released in the preceding step. | 11-20-2014 |

20080264454 | Method for cleaning hollow tubing and fibers - Hollow porous fibers containing adhered contaminants are cleaned to remove the contaminants by backflushing a liquid to fill the pores, and adding a flow of gas so as to form a two-phase mixture of gas and bubbles of liquid that can scrub the fibers, loosening the contaminants and allowing them to be flushed from the hollow fibers. The method is particularly useful for cleaning hemodialyzers used for dialysis and hollow fiber modules used in water treatment and separations. The two phase flow method is specifically effective in cleaning piping systems having high length to diameter (l/d) ratios. | 10-30-2008 |
20100078046 | Apparatus and method for cleaning passageways such as endoscope channels using flow of liquid and gas - Apparatus and methods are disclosed for cleaning interiors of passageways in endoscopes or other luminal medical devices by flow of liquid and gas therethrough. The liquid flow may include rivulets, droplets or other liquid entities which move on the internal surfaces of the passageways, and may include a three-phase contact interface between liquid and dry solid and gas. | 04-01-2010 |
20100078047 | Method and composition for cleaning tubular systems employing moving three-phase contact lines - A method, composition and apparatus for cleaning an internal surface of a narrow diameter channel. The method includes: | 04-01-2010 |
20120234357 | METHOD FOR COMPOSITION FOR CLEANING TUBULAR SYSTEMS EMPLOYING MOVING THREE-PHASE LINES - A method for cleaning an internal surface of a narrow diameter channel includes steps of flowing a liquid cleaning medium and a gas through the narrow diameter channel under a flow regime that creates surface flow entities in contact with and sliding along the internal surface of the narrow diameter channel, said surface flow entities having three-phase contact lines and associated menisci, said surface flow entities detaching contaminants with which they come in contact from the internal surface of the narrow diameter internal surface of the narrow diameter channel; and rinsing the internal surface of the narrow diameter channel to remove residual liquid cleaning medium and detached contaminants from the channel. | 09-20-2012 |
