Title: Device for neutralizing electromagnetic radiation
Inventor: NEDELJKOVIC VOISLAV
IPC: A61N1/16
Filed: 2001-08-03
Granted: 2012-06-26
Abstract: A neutralizer for electromagnetic radiation, particularly harmful radiation, caused by electro-magnetic fields from electric lines, installations, machines, appliances and apparatus includes a cylindrical body (1) with a semi-circular external groove (2) and two cylindrical chambers (4). A bar core (5) in the chambers (4) has solenoids (S) rotatably mounted thereon. Chambers (4) are hermetically closed by thread plugs (6). The difference in electrical potentials between the body (1) and the solenoid (S) causes a weak electric field of high frequency that annuls the effect of technical radiation in its environment.

Abstract: The present invention relates to apparatus and methods for remotely actuating a downhole tool. In one aspect, the present invention provides an apparatus for activating a downhole tool in a wellbore, the downhole tool having an actuated and unactuated positions. The apparatus includes an actuator for operating the downhole tool between the actuated and unactuated positions; a controller for activating the actuator; and a sensor for detecting a condition in the wellbore, wherein the detected condition is transmitted to the controller, thereby causing the actuator to operate the downhole tool. In one embodiment, conditions in the wellbore are generated at the surface, which is later detected downhole. These conditions include changes in pressure, temperature, vibration, or flow rate. In another embodiment, a fiber optic signal may be transmitted downhole to the sensor. In another embodiment still, a radio frequency tag is dropped into the wellbore for detection by the sensor.

Title: Processing packets based on context indications
Inventor: PULLELA VENKATESHWAR
IPC: H04L12/56
Filed: 2003-03-15
Granted: 2010-03-23
Abstract: A context vector, typically used in a lookup operation of an associative memory, is generated based on a context of a received packet and the packet itself. In one implementation, multiple interfaces can share a common access control list as the context vector provides an indication of the result of unique processing required because of varying contexts, such as, but not limited to different interfaces, source addresses, and virtual network addresses. One implementation includes an input interface circuitry, a context indicator generator, a lookup word field generator, and an associative memory.  The context indicator generator generates a context vector corresponding to a characteristic of the input interface circuitry. The lookup word field generator generates one or more lookup word vectors based on the packet. The associative memory performs a lookup operation based on the context vector and lookup word vectors.

Title: Surgical stapling instrument having a single lockout mechanism for prevention of firing
Inventor: DOLL KEVIN
IPC: A61B17/072
Filed: 2004-10-15
Granted: 2012-07-10
Abstract: A surgical instrument for laparoscopic and endoscopic clinical procedures simultaneously severs and staples tissue clamped in an end effector comprising an elongate channel, which holds a staple cartridge, and a pivotally attached anvil. An E-beam firing bar engages the channel and selectively engages the anvil during distal firing movements, wherein the tissue is severed and stapled driven upward from the staple cartridge to form against the anvil. In particular, a wedge integral to the staple cartridge is driven distally by a middle pin of the f ring bar to effect stapling. A single lockout of the elongate channel responds to the presence of the wedge sled in its unfired position to allow the firing bar to fire. Otherwise, the single lockout prevents firing when the staple cartridge is missing or spent.

Granted: 2011-01-04
Abstract: Precious metals such as gold can be extracted from a refractory ore using a conventional cyanide leaching step and with reduced cyanide consumption by pre-treating the ore prior to cyanide leaching. The refractory ore is pretreated by fine grinding and an initial leaching step which uses inexpensive limestone and lime to maintain the initial leach relatively alkaline. Oxygen is added to the initial leaching step and the conditions are carefully controlled to only partially oxidize the ground ore to between 9-15 %. The initial leaching step can be carried out at temperatures of less than 100 degrees C and at atmospheric pressures. The pre-treated ore is then leached by a conventional cyanide leaching step to recover the precious metal and cyanide consumption can be reduced by more than two thirds.

Title: Controlled separation heart valve frame
Inventor: MARQUEZ SALVADOR
IPC: A61F2/24
Filed: 2005-03-24
Granted: 2013-05-07
Abstract: A highly flexible prosthetic heart valve having an internal leaflet support frame that is designed to separate into individual cusps after implantation. The leaflet support frame (or "stent" or "wireform") has a plurality of alternating cusps (26) on an inflow end and commissures (44) on an outflow end. The cusps of flexible leaflets attach around the support frame cusps.  The support frame (40) provides structural rigidity during implantation, but each support frame commissure has a point of weakness (76) that is designed to fracture upon repeated relative movement of the cusps after implantation such that the support frame cusps separate. Because of the flexible nature of the heart valve, after the cusps separate the implanted heart valve does not significantly impede the natural motions of the annulus or adjacent vessel walls. The support frame may be a homogeneous material such as Nitinol with the point of weakness being a narrowing at the commissure tips.  The commissure tips can include enlarged regions adjacent the point of weakness that help prevent the separated ends from poking through surrounding fabric.
