Assignee:

Advanced Micro Devices, Inc. - Sunnyvale CA

International Classification:

H01L 21461

US Classification:

438744, 438672, 438735

Abstract:

A method of fabricating an integrated circuit can include providing a layer of silicon nitride over a semiconductor substrate where the layer of silicon nitride has a first thickness selected based on a desired size of extensions; providing a layer of photoresist material over the layer of silicon nitride; patterning the layer of photoresist to form photoresist features being separated at the top of the photoresist features by one minimum lithographic feature and etching a portion of the layer of silicon nitride to form a hole for an integrated circuit device feature. The photoresist features include extensions at the bottom of the photoresist features. The extensions define footings. These footings reduce the separation at the bottom of the photoresist features. As such, exposed portions of the layer of silicon nitride are less than one minimum lithographic feature in width.

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

H04L 12/28

US Classification:

370389, 711108

Abstract:

A technique for classifying traffic at a network node involves programming a content addressable memory (CAM) array with multiple class-specific entries, where each of the class-specific entries has an associated traffic class, obtaining a protocol-independent key field from an incoming packet, and searching the programmed CAM array with the protocol-independent key field to identify an associated traffic class of the incoming packet. In another embodiment, each of the class-specific entries has an associated traffic distribution policy, which may be applied to an incoming packet.

Abstract:

A packet stream multiplexer may include one or more control loops (e. g. , digital phase locked loops) for tracking the source clock frequency associated with a packet stream. A first control loop may slowly drive an error between a received timestamp and an estimated timestamp to zero. A second control loop may more quickly drive a first derivative of the error to zero. The second control loop may include a set of digital filters ordered according to tracking speed. The output of the slowest filter is initially selected for updating the source clock frequency estimate. As time progresses, the faster filters are selected in succession. The estimated source clock frequency is used to restamp packets of the packet stream as they are sent out onto an output channel.

International Classification:

G06F 9/44

US Classification:

717113, 717106, 717121, 715765

Abstract:

Systems and methods for applying both profile and user customizations to an application user interface are provided. Profile customizations, created for a specialized use or field, are adapted to an application user interface, which has command-menu-toolbar contributions from various add-in modules. The user has access to the customizations through a user interface. Then, as a user is customizing the application, through commands, toolbars, and menus, the user customizations are tagged. A priority and group is assigned to each customization to allow for relative positioning of each customization. The difference between the user's final desired state and a reset state is computed. This difference computation is used to track the changes made to the application and to assist in resets of the customizations.

US Classification:

369 4747, 369 4738

Abstract:

A method and system for controlling the spin rate of an optical device. A device driver provides notification that media has been inserted into the optical device. A control service determines the format of information on the media. The spin rate of the optical device is locked or unlocked based on the format.

International Classification:

G01R 27/02
G06F 1/26

US Classification:

324722, 324713, 713300

Abstract:

A system and method for measuring a cable resistance in a power over Ethernet (PoE) application. A short circuit module in a powered device is designed to produce a short circuit effect upon receipt of a cable resistance detection voltage. The cable resistance detection voltage can be designed to be greater than a voltage for detection or classification and less than a voltage for powering of the powered device. The measurement of the current at a time when a short circuit effect is produced at the powered device enables a calculation of the actual resistance of the cable on a given PoE port.
