Appl. No.:

11/751383

Inventors:

Amit Mhatre - Sunnyvale CA, US
Jian Yao Wu - San Jose CA, US
Mitchell Wenger - Ross CA, US
Steven Friedman - San Francisco CA, US

Assignee:

Asante Solutions, Inc. - Sunnyvale CA

International Classification:

A61M 31/00

US Classification:

604 65

Abstract:

Some embodiments of an infusion pump system may include an occlusion sensor that can be used to detect when an occlusion exists in the fluid path between the medicine reservoir and the infusion site on the user's skin. Such an occlusion may occur, for example, when the fluid flow line (e. g. , a cannula, infusion set tubing, or the like) is kinked. If the medicine dispensation path to the user is occluded, the user may receive no dosage or a lower dosage of the medicine. As such, the occlusion sensor can be used to indicate when the fluid is flowing or not flowing, thereby permitting the infusion pump system to communicate an alarm to the user if an occlusion exists.

International Classification:

E21B 34/00
E21B 10/36

US Classification:

166321, 175428

Abstract:

A downhole tool assembly is configured for repeated and selective hydraulic actuation and deactuation. A piston assembly is configured to reciprocate axially in a downhole tool body. The piston assembly reciprocates between a first axial position and second and third axial positions that axially oppose the first position. The downhole tool is actuated when the piston assembly is in the third axial position and deactuated when the piston assembly is in either of the first or second axial positions. A spring member biases the piston assembly towards the first axial position while drilling fluid pressure in the tool body urges the piston assembly towards the second and third axial positions. Downhole tool actuation and deactuation may be controlled from the surface, for example, via cycling the drilling fluid flow rate.

Abstract:

Structures and methods to enhance cycling endurance of BEOL memory elements are disclosed. In some embodiments, a memory element can include a support layer having a smooth and planar upper surface as deposited or as created by additional processing. A first electrode is formed the smooth and planar upper surface. The support layer can be configured to influence the formation of the first electrode to determine a substantially smooth surface of the first electrode. The memory element is formed over the first electrode having the substantially smooth surface, the memory element including one or more layers of an insulating metal oxide (IMO) operative to exchange ions to store a plurality of resistive states. The substantially smooth surface of the first electrode provides for uniform current densities through unit cross-sectional areas of the IMO. The memory element can include one or more layers of a conductive metal oxide (CMO).
