Assignee:

Applied Materials, Inc. - Santa Clara CA

International Classification:

C02F 1461

US Classification:

2042291, 2042301, 2042307, 204272

Abstract:

A method and assembly for recovering a metal from by-products produced from etching a metal (e. g. , platinum, iridium, aluminum, etc. ) in a plasma processing chamber. The method includes recovering from the plasma processing chamber a deposit of the by-products containing the metal. The deposit is dissolved in an acid, and the metal is recovered from the acid by inserting a working electrode, a reference electrode, and a counter electrode into the acid and applying a difference in potential between the working and reference electrodes to cause current to flow through the working and counter electrodes and the metal to be removed from the liquid and deposit on the working electrode. The metal is removed from the working electrode to recover the metal. The assembly for recovering the metal from the by-products includes a potentiostat for effecting a difference in potential between the working and reference electrodes and causing current to flow through the working and counter electrodes in response to the difference in potential between the working and reference electrodes.

Assignee:

iStor Networks, Inc. - Irvine CA

International Classification:

H04L 1/18
G08C 25/02

US Classification:

714748

Abstract:

Disclosed is a system and methods for accelerating network protocol processing for devices configured to process network traffic at relatively high data rates. The system incorporates a hardware-accelerated protocol processing module that handles steady state network traffic and a software-based processing module that handles infrequent and exception cases in network traffic processing.

US Classification:

370/232000, 370/235000, 709/223000

Abstract:

A data switching engine is provided. The data switching engine includes a switching processor used for data traffic forwarding and an traffic management processor used for data traffic management. The switching processor retains all functionality of currently deployed data switching equipment as it relates to data switching and forwarding. The traffic management processor performs data traffic characterization, statistics extraction, service level agreement enforcement, etc. The use of the traffic management processor reduces computational loads otherwise imposed on the switching processor while maintaining or surpassing levels of service provided by currently deployed data switching equipment.
