International Classification:

G06F 1730

US Classification:

707102, 707100, 707103

Abstract:

A method and system for modeling of object-oriented database structures, translation to relational database structures, and dynamic searches thereon. The user may create, edit and manipulate a users object database (dynamically translated into a set of relational database structures), to create, edit and manipulate objects for that object database (dynamically translated into data for those relational database structures), and to create, edit and manipulate queries to be applied to that object database (dynamically translated into queries to be applied to those relational database structures). A meta-model of the users object database, which is itself an object database, and which has itself been translated into a set of relational database structures for manipulation by a relational database engine. The meta-model comprises a set of classes, objects, and relationships between classes which model the classes and relationships between classes of the system. Each of these classes may comprise a set of searchable properties, and each of these relationships may comprise an inheritance relationship (between a base class and a derived class) or a data-model relationship (such as a one-to-one, one-to-many, or many-to-many relationship).

Assignee:

JDS Uniphase Corporation - San Jose CA

International Classification:

G02B 530

US Classification:

359484, 359495, 359496, 359497, 359282, 385 11, 385 31, 385 33

Abstract:

An optical circulator having a dual fiber collimator and a single fiber collimator is described. The circulator provides a non-reciprocal functionality that directs input signals from a first fiber of the dual fiber collimator to the single fiber collimator. Input signals from the single fiber collimator are directed to a second fiber of the dual fiber collimator. The circulator includes birefringent wedges that change the angle of signals from the single fiber collimator to direct the signals to the second fiber of the dual fiber collimator. Because the circulator includes two collimators rather than three collimators, the circulator is more compact than a circulator having three collimators.

Assignee:

Synopsys, Inc. - Moutain View CA

International Classification:

G11C 11/00

US Classification:

365154, 36518909, 36523006

Abstract:

A source-biasing mechanism for leakage reduction in SRAM in which SRAM cells are arranged into a plurality of sectors. In standby mode, the SRAM cells in a sector in the plurality of sectors are deselected and a source-biasing potential is provided to the SRAM cells of the plurality sectors. In working mode, the source-biasing potential provided to the SRAM cells of a selected sector in the plurality of sectors is deactivated and the SRAM cells in a physical row within the selected sector are read while the remaining SRAM cells in the unselected sectors continue to be source-biased. The source-biasing potential provided to the SRAM cells that are in standby mode can be set to different voltages based on the logical state of control signals.

International Classification:

H03L 7/00

US Classification:

327143, 327 81

Abstract:

Power up circuit. An example power up circuit includes a switch for charging a power node of an electronic device. A level detector is used for monitoring charge level of the power node. Further, the power up circuit includes one or more power switches for providing current to the electronic device based on the charge level.

US Classification:

365194, 365191

Abstract:

A memory has a tracking circuit for a read tracking operation. The memory includes a memory bit cell array, a tracking column, a tracking row, a sense amplifier row coupled to the memory bit cell array and the tracking row, and a sense amplifier enable logic. The memory further includes a tracking bit line coupled to the tracking column and the sense amplifier enable logic, and a tracking word line coupled to the tracking row and the sense amplifier enable logic. The tracking circuit is configured to track a column time delay along the tracking column before a row time delay along the tracking row.

Abstract:

Disclosed herein are methods of producing metal nanoparticle-decorated carbon nanotubes. The methods include forming a reaction mixture by combining a first solution with a second solution, wherein the first solution comprises polymer-coated metal nanoparticles comprising metallic nanoparticles coated with a polymer, and wherein the second solution comprises carbon nanotubes. The methods also include heating the reaction mixture to a temperature greater than a glass transition temperature of the polymer for a time sufficient to cause the polymer-coated metal nanoparticles to bind to the carbon nanotubes forming the metal nanoparticle-decorated carbon nanotubes.
