20050171752, Aug 4, 2005

Filed:

Jan 29, 2004

Appl. No.:

10/767524

Inventors:

Jonathan Patrizio - San Francisco CA, US
Eric Soderberg - Mountain View CA, US
James Curtis - Placerville CA, US

International Classification:

G06F017/50

US Classification:

703017000

Abstract:

A cluster simulator simulates reformation of a real cluster in response to failure events. Profile programs on the cluster can gather data useful to the simulation and transmit the profile data to the simulator. The simulator can generate a model of the real cluster, the model itself being a virtual cluster. A user can select virtual failure events from a menu to apply to the model and the simulator responds by generating a post-failure virtual cluster in the configuration that the real cluster would assume in the event of the corresponding real failure. Sequences of virtual failures can also be tested for a given cluster configuration to evaluate its robustness. Comprehensive testing using virtual failure sequences can also be applied to different cluster configuration so that an optimum configuration can be recommended.

Appl. No.:

13/598176

Inventors:

James R. Curtis - Sunnyvale CA, US

International Classification:

A61M 1/16

US Classification:

210647, 210101, 210 90

Abstract:

A medical dialysis system including a filtration system configured to filter a water stream, a water purification system configured to purify the water stream in a non-batch process, a mixing system, and a dialyzer system. The mixing system includes a supply of dialysate components, a conductivity sensor positioned within a fluid pathway through which the water stream flows, and a control mechanism having a pump configured to control an amount of the one or more dialysate components added to the water stream from the supply. The mixing system can produce a stream of dialysate from mixing the one or more dialysate components with the water stream in a non-batch process. The dialyzer system includes a dialyzer, a plurality of pumps capable of pumping the stream of dialysate across the dialyzer, and another conductivity sensor positioned downstream of the dialyzer within a fluid pathway through which the water stream flows.

International Classification:

B23K 2600

US Classification:

21912169

Abstract:

A process is provided for preparing a three dimensional object such as a mandrel for forming envelopes for mammary prostheses or other implantable medical device by dipping the mandrel, etc. The envelopes are provided with micropillars on the exterior surface which resembles the mandrel surface in negative relief. According to the process a workpiece of solid stock material such as polymer is provided in the shape of the desired prostheses. It is positioned for rotation on a supporting shaft or other holding mechanism. A pulsing laser beam, directed at the workpiece is moved in a plane parallel to the axis of rotation of the workpiece while the beam is maintained approximately perpendicular to the workpiece surface. The rate of pulsing of the laser beam and the speed of rotation of the workpiece are controlled to produce patterns of blind micro-holes onthe surface of the workpiece. A noncircular pattern can be produced by oscillating the beam toward and away from the axis of rotation with each revolution of the workpiece.

Abstract:

Dialysis systems and methods are described which can include a number of features. The dialysis systems described can be to provide dialysis therapy to a patient in the comfort of their own home. The dialysis system can be configured to prepare purified water from a tap water source in real-time that is used for creating a dialysate solution. The dialysis systems described also include features that make it easy for a patient to self-administer therapy. For example, the dialysis systems include disposable cartridge and patient tubing sets that are easily installed on the dialysis system and automatically align the tubing set, sensors, venous drip chamber, and other features with the corresponding components on the dialysis system. Methods of use are also provided, including automated priming sequences, blood return sequences, and dynamic balancing methods for controlling a rate of fluid transfer during different types of dialysis, including hemodialysis, ultrafiltration, and hemodiafiltration.
