Filed:

Mar 1, 2010

Appl. No.:

12/715306

Inventors:

Anthony Siress - Mountain View CA, US
Mark Fitzpatrick - San Mateo CA, US

Assignee:

YOUnite, Inc. - Mountain View CA

International Classification:

G06F 15/16

US Classification:

709229, 707769, 707802

Abstract:

Creating an agency relationship among clients of a computer system with respect to personal privileged, or otherwise sensitive permissions and/or attributes, is described. The technique enables a querying client to obtain permission and/or attributes from a queried client, even if the queried client is unavailable.

Filed:

Jun 3, 2010

Appl. No.:

12/793597

Inventors:

Anthony Siress - Mountain View CA, US
Mark Fitzpatrick - San Mateo CA, US

Assignee:

YOUnite, Inc. - Mountain View CA

International Classification:

G06F 17/30

US Classification:

707781, 709229

Abstract:

Granting permissions for attributes in a distributed data store involves implementing a federated control system. The system can include dynamic permissions granted to content blobs. Acknowledgment of dynamic permissions facilitates identification of users that receive content to enable restoring data on a machine following data loss. Acceptance of dynamic permissions can further facilitate automatic updates to data, or providing content blobs in response to changes in user attributes.

Filed:

Dec 20, 2006

Appl. No.:

11/643064

Inventors:

Anthony Siress - Mountain View CA, US
Mark Fitzpatrick - San Mateo CA, US

International Classification:

G06F 17/30

US Classification:

707009000

Abstract:

Methods and systems are described for controlling query access to attributes associated with subscribers of a system. Permission setting variables are provided to allow subscribers considerable control over query access to attributes associated with the subscribers. A subscriber may manipulate one or more permission setting variables to control aspects of the response a querying party may receive when a query matches attributes associated with the subscriber. Advantages of the invention include flexible management of query access to subscriber information.

US Patent:

Filed:

Apr 5, 1990

Appl. No.:

7/505858

Inventors:

Mark E. Fitzpatrick - San Jose CA
Robert C. Burd - Sunnyvale CA

Assignee:

Gazelle Microcircuits, Inc. - Santa Clara CA

International Classification:

G05F 146
G05F 308

US Classification:

323312

Abstract:

A switch means is disclosed which enables two or more terminals normally having a wide operating voltage to be connected by a pass transistor. A biasing means applies a voltage to the gate of the pass transistor which turns on the pass transistor without forward biasing any inherent diodes within the pass transistor.

Filed:

Sep 10, 1987

Appl. No.:

7/095284

Inventors:

Gary R. Gouldsberry - Cupertino CA
Mark E. Fitzpatrick - San Jose CA

Assignee:

Gazelle Microcircuits, Inc. - Santa Clara CA

International Classification:

G01R 1512

US Classification:

324158R

Abstract:

A semiconductor device includes as part of the integrated circuit thereof a test structure which allows testing of the semiconductor device through the device pins, to allow adjustment of various parameters of the circuit if desired for obtainment of optimum performance, and with the circuit being operable under normal conditions without degradation in relation to its optimum design situation.

Assignee:

Monolithic Memories, Incorporated - Santa Clara CA

International Classification:

G01R 1512

US Classification:

324 73PC

Abstract:

Test circuitry is included in a PROM memory for detecting shorts between bit lines and word lines and shorts or leaks in a memory cell. The circuitry enables a selected positive voltage to be applied across all memory cells in the memory so that the existance of leaky memory cells or shorts in the memory can be detected during testing. The test circuitry has no appreciable effect on the memory during normal operation of the memory.

Appl. No.:

7/506418

Inventors:

Mark E. Fitzpatrick - San Jose CA
Gary R. Gouldsberry - Cupertino CA

Assignee:

Gazelle Microcircuits, Inc. - Santa Clara CA

International Classification:

G05F 308

US Classification:

323317

Abstract:

In a current pump, three separate current sources, each providing an identical current, are used. A first current pump is provided between an output load and a positive power supply terminal to provide a positive current to a load. To enable the current pump to provide a zero current to the load or withdraw a current from the load, second and third current pumps are provided in parallel between the load and a ground terminal. Associated switches couple these second and third current sources to the load. Thus, three states of the current pump are available which provide either a positive current, a negative current, or a zero current to a load.
