Filed:

Apr 11, 2011

Appl. No.:

13/084502

Inventors:

Thomas A. Riddle - Belmont CA, US
Darpan Dinker - Union City CA, US
Andrew D. Eckhardt - Menlo Park CA, US
Michael J. Koster - Bridgeville CA, US

International Classification:

G06F 12/00

US Classification:

711103, 711E12008

Abstract:

Approaches for a distributed storage system that comprises a plurality of nodes. Each node, of the plurality of nodes, executes one or more application processes which are capable of accessing persistent shared memory. The persistent shared memory is implemented by solid state devices physically maintained on each of the plurality of nodes. Each the one or more application processes, maintained on a particular node, of the plurality of nodes, communicates with a shared data fabric (SDF) to access the persistent shared memory. The persistent shared memory comprises a scoreboard implemented in shared DRAM memory that is mapped to a persistent storage. The scoreboard provides a crash tolerant mechanism for enabling application processes to communicate with the shared data fabric (SDF).

Appl. No.:

8/332322

Inventors:

Gary A. Lattin - Forest Lake MN
Thomas A. Riddle - Sunnyvale CA

Assignee:

Alza Corporation - Palo Alto CA

International Classification:

A61N 130
A61M 1100

US Classification:

604 20

Abstract:

An electrotransport system (20) for delivering a therapeutic agent (36) through a body surface (40) (eg, skin) of a patient includes a pair of electrodes (34, 38) for contacting the body surface, at least one of which contains the therapeutic agent (36). The system (20) is physically separated into a control unit (22) and a delivery unit (24) connected by a radiated energy signal-based telemetry link. The telemetry link may be radio frequency, ultrasonic, optical, infrared or inductively coupled. Signals from the control unit may be transmitted to the delivery unit by the telemetry link, or vice versa. The delivery unit may control electrotransport current on the signal transmitted. The radiated energy signal may be encoded to improve immunity to extrinsic interference. The delivery unit (24) may be configured with sensor means for detecting a condition such as a body or system parameter reaching some predetermined limit.

Appl. No.:

7/820704

Inventors:

Thomas A. Riddle - San Francisco CA
Johan H. Geerke - Los Altos CA
Keith P. Minton - San Jose CA

Assignee:

Alza Corporation - Palo Alto CA

International Classification:

B23K 2600

US Classification:

2191217

Abstract:

Tablet treating system 10 treats a series of pharmaceutical tablets 50T with pulses of laser energy 24P within at least one predetermined treatment site 50S on each tablet. A tablet conveyer 12 continuously moves individual tablets along a tablet path 10P. A Laser 14 provides the pulses of laser energy along a stationary laser path which crosses the tablet path defining a stationary intersection zone 14Z common to both paths. The tablet path has periodic treatment windows 20W during which the treatment sites 50S on the moving tablets pass through the stationary intersection zone. The operation of the laser has periodic laser ready windows 24W during which the laser may be fired. A controller 16 is responsive to the movement of the tablet conveyer and to the operation of the laser for activating the laser and treating the tablets. The controller activates the laser when a tablet is passing through the intersection zone and the tablet treatment window coincides with the laser ready window. The controller does not activate the laser and rejects the tablet when the tablet treatment window does not coincide with the laser ready window.
