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.

International Classification:

H04L 900

US Classification:

713176, 705 3

Abstract:

A medical image management system including an image archive server for storing image datasets received from a plurality of image acquisition computers and a plurality of display stations for displaying requested image datasets retrieved from the image archive server is provided with an authentication and security system which includes an authentication server for maintaining and storing hashes and timestamps, and for providing hash, timestamp pairs in encrypted form in response to requests from display stations. The image acquisition computers are configured for computing hashes and providing them and image dataset identifiers to the authentication server, receiving timestamps from the authentication server which are then inserted in the image datasets, and storing the image datasets in the image archive server. The display stations are configured for retrieving image dataset, computing hashes from retrieved image datasets, requesting and decrypting hash/timestamp pairs received from the authentication server, and comparing the hashes, and optionally the timestamps, obtained from the authentication server with those computed or extracted from the image datasets received from the image archive server.

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:

H04L 12/66

US Classification:

370463

Abstract:

A system includes one or more processing units coupled to a network interface unit. The network interface unit may include a network port for connection to a network and a virtual interface that may be configured to distribute an available communication bandwidth of the network port between the one or more processing units. The network port may include a shared media access control (MAC) unit. The virtual interface may include a plurality of processing unit resources each associated with a respective one of the one or more processing units. Each of the processing unit resources may include an I/O interface unit coupled to a respective one of the one or more processing units via an I/O interconnect, and an independent programmable virtual MAC unit that is programmably configured by the respective one of the one or more processing units. The virtual interface may also include a receive datapath and a transmit datapath that are coupled between and shared by the plurality of processing unit resources and the network port.

International Classification:

H03H 2/00
H04B 3/00

US Classification:

333 24R, 375257

Abstract:

A system and method for enabling power applications over a single conductor pair. In one embodiment, data transformers are coupled to a single conductor pair using one or more direct current (DC) blocking elements that preserve an alternating current path. Power is injected onto the single conductor pair after the DC blocking elements and power is extracted from the single conductor pair before the DC blocking elements. Saturation of the data transformers by the injection of power onto the single pair is thereby prevented.

International Classification:

G06F 1/26

US Classification:

713300

Abstract:

An active powered device (PD) for the application of power over Ethernet (PoE). In a fixed power budget environment, it is important for the power sourcing equipment (PSE) to accurately determine a power budget for the various powered ports. An active PD can be designed to gather additional information (e.g., current and input voltage) during PD operation and to forward the additional information to the PSE. The PSE can then use the additional information to adjust operational parameters such as a power budget.
