Abstract: A method and system for optimizing the pose of a picking tool with respect to at least one previously selected item in a topmost layer of target items to be picked from a transport structure are provided. The method includes the step of generating all legal poses of the picking tool with respect to the configuration of items on the topmost layer in which the picking tool subtends the at least one previously selected item. The method also includes selecting the picking tool pose for picking the at least one previously selected item based on the generated legal poses.

Abstract: This invention relates to a medical device. The device includes an elongate cannula which is insertable into a blood vessel and which is resiliently biased towards a closed condition in which it inhibits fluid flow through the cannula. The cannula is displaceable away from its closed position by the introduction of a displacement arrangement such as a device or instrument or a pressurised fluid and reverts to its closed condition when the displacement arrangement is removed from the cannula to inhibit the flow of blood therethrough. The invention further relates to a needle for use with the medical device, to a kit and to a method of accessing a blood vessel. In addition, it relates to a method of closing an incision in a blood vessel and to a closure member for use in the method.

Abstract: A selective downhole actuator comprising at least a first actuator position, a second actuator position and a third actuator position. The selective downhole actuator is reconfigurable between the first actuator position and the second actuator position. The selective actuator is selectively reconfigurable to the third actuator position by varying an operating parameter during a transition of the selective downhole actuator between the first and second actuator positions.

Abstract: A drilling assembly assembly includes a hammer motor, a shaft, a driver, and a hammer (218). The shaft is operatively connectable to the hammer motor and rotated thereby. The driver is operatively connectable to the shaft, and includes a cam (such as guide channel 232) rotatable with the shaft and a fixed guide (such as guide pins 230) having a guide surface thereon. The cam is engageable with the guide surface and axially movable thereabout during rotation thereof. The hammer is operatively connectable to the driver and axially movable therewith, axially movable within the housing (215) independently from axial movement of the housing, and engageable with the bit to impart an impact thereto whereby the bit is hammered.

Abstract: The present invention relates generally to the field of pharmaceutical formulations of antibodies. Specifically, the present invention relates to a high concentration antibody formulation and its pharmaceutical preparation and use. This invention is exemplified by a formulation of an anti-IL-7R antibody.

Abstract: A lip seal assembly is disclosed. The lip seal assembly includes a seal; an upper backing ring disposed below the seal; and a lower backing ring disposed below the upper backing ring. The upper and lower backing rings are configured to distort in a predetermined manner.

Abstract: A downhole tool comprises a body defining a fluid inlet and two or more fluid outlets. A valve arrangement cycles the proportion of fluid directed from the inlet to each of the outlets. One of the outlets may be associated with a fluid pressure responsive device, such as a cleaning blade.

Abstract: To provide a protective coat on a refrigerated sample collector for a corrosive environment a unitary frame includes a support unit with condenser and evaporator coils mounted to the support unit and an orifice connecting the condenser and evaporator coils. The evaporator coils, condenser coils and a restrictor are powder coated after being connected, whereby an effective seal is provided for the restrictor, condenser coils and evaporator coils after they are assembled to the support. The unitary frame can be easily removed or connected as a unit to the sample collector. The bottle rack for the sample collector is made by injection molding two halves of the rack each of which has a matching surface and a bottle positioning surface. The matching surfaces are fastened together by placing the matching surfaces together back to back whereby locating members are spaced apart a sufficient distance. To position a distributor in the sample collector, an index disk rotates with the distributor.

Abstract: A filtration apparatus comprises a plurality of filtration sections such as (12, 13), each covered on both opposed faces by a filter cloth (14). Each filter cloth (14) is formed with a compressible edge bead (26) which is received in a corresponding groove (22-25) in a member (20) which extends between the sections (12, 13). The grooves each have an orifice for reception of the edge beads which is less than the diameter of the groove. Member (20) has a hollow core (21) to receive a sector dividing stem (17) to pass along and reinforce the member (20).

Abstract: A multiple chamber sample holding cartridge is used with a supercritical fluid extractor that causes membranes dividing the cartridge into chambers to rupture upon the pressurization of the sample cartridge, thereby allowing the intermixing of materials contained in the chambers. The neutral oil and loss determination of soybean and other oilseed oils by supercritical fluid extraction is efficient with this two-chambered sample cartridge.

Abstract: An injection syringe for injecting a fluid into the arterial, venous, muscular or cavity structures of a patient via subcutaneous, percutaneous, intravascular and other types of injections comprises a hollow syringe body, a passageway at a distal end of the syringe for passage of fluid into and out of the syringe and a substantially open proximal end for receiving a plunger assembly. The plunger assembly includes a movable plunger assembly. A moveable plunger cooperates with the syringe body and the proximal end of the syringe to define a fluid chamber of variable volume in fluid communication with the passageway. Actuating means actuates movement of the plunger. An elastomeric barrier cooperates with the plunger and the open end of the syringe to define a sterile chamber between the actuating means and the fluid chamber to prevent passage of fluids from the fluid chamber to the actuating means and the passage of contaminants from the open end of the syringe in the fluid chamber.

Abstract: A connection procedure for finding by rearrangement a path for multirate, multicast traffic through an SDH cross-connect with subnetwork connection protection. If no free path for a new payload through the SDH switching hardware is available, the switching procedure looks for a path that is adequate and blocked by the least existing payload capacity. If the hunt is successful, the procedure rearranges the existing connections to make possible a path for the new payload. The procedure does not interrupt the existing connections; thus it is a "hitless" procedure. Connections for existing payloads that must be moved to make way for the new payload are queued and the connection procedure is applied recursively, to each in turn, until the queue is empty.
