Abstract:

The shapes of the photo-resist layer “banks” which define pockets for inkjet printing or other patterned processes are optimized to provide a more uniform drying profile for substances which are to be deposited in those pockets and dried therein. Preferably, the shapes of the banks are “mushroom” shaped such that a portion of the photo-resist layer overhangs the exposed lower electrode layer.

US Classification:

370235, 370252

Abstract:

The Fibre-Channel flow control mechanism is augmented to facilitate efficient data exchange between Fibre-Channel ports over extended distances. A supplemental buffer mechanism may be maintained as part of an interface to a transport network used to carry Fibre-Channel traffic. The transport network interface makes a remote Fibre-Channel port aware of the augmented local receiver buffer capacity by intercepting certain frames used in link establishment and substituting an enhanced buffer capacity for the local Fibre-Channel port's internal buffer capacity. This technique provides improved throughput and readily accommodates large distances and large frame sizes.

US Classification:

370392, 370469

Abstract:

A multiprotocol encapsulation method and system for transporting different protocols over Ethernet are disclosed. The method includes receiving frames from an optical interface and identifying a protocol of the frame. The frames are multiprotocol and include storage network interface protocols. The frames are encapsulated into Ethernet protocol and transported over an Ethernet link.

International Classification:

US Classification:

370235, 370252, 370412

Abstract:

Oversubscription of Fibre Channel links over a transport network is provided. A transport interface according to the present invention may maintain a small ingress buffer in addition to the normal egress buffer. The ingress buffer is primarily used for oversubscription and the egress buffer is primarily used for flow control. Ready indications to multiple local Fibre Channel ports may be locally generated when flow control conditions permit and may be distributed among the local Fibre Channel ports in response to preconfigured bandwidth sharing weights. Transport network efficiency is achieved by statistical multiplexing without significant increase in buffer memory requirements or introduction of latency into the flow control mechanism.

US Classification:

370252, 370389, 370466, 398 25

Abstract:

The link status of a Fibre-Channel link interconnecting two Fibre-Channel ports may be determined by a third entity distinct from the two Fibre-Channel ports. The third entity may be a transport interface used to connect one of the Fibre-Channel ports to a transport network that carries the link. The transport interface may also learn the Fibre-Channel port types of the two ports.

Abstract:

A method for negotiating speed between a Fiber Channel (FC) local client and a remote FC client across a DWDM network is provided. A transmission speed of the local FC client at a local ingress transport interface is detected. The data from the local FC client is forwarded along with the detected transmission speed to a remote egress transport interface. The remote egress interface forwards the data at the detected transmission speed to the remote FC client. The present invention eliminates complex speed negotiation state machines that would otherwise be required to make the DWDM transport behave like a virtual wire with respect to the FC ports and to allow the FC clients to negotiate the desired speed directly between themselves.

Abstract:

A method for automated evaluation of a SPAM filter rates a sender-receiver pair based on traffic information related to the sender-receiver pair. A SPAM filter intercepts electronic messages transmitted between the sender-receiver pair and classifies them as either SPAM or HAM. On comparing the rating for the sender-receiver pair and the classification for an electronic message between the sender-receiver pair, the method generates a metric indicating the reliability of the spam filter. Repeating these steps for more than one electronic messages and related sender-receiver pairs, the method produces a set of metrics. One or more of the metrics from the set of metrics are used to calculate an evaluation factor for evaluating the SPAM filter.

Abstract:

An organic polymer solution is made of at least one organic polymer, a first solvent, and a second solvent. The first solvent has a high solubility (e.g., the first solvent dissolves at least about one weight percent of the organic polymers) and has a faster evaporation rate than the second solvent, and the second solvent has a very low solubility (e.g., the second solvent dissolves less than about one-fourth weight percent of the organic polymers). After the solution is deposited on an object, the solution is allowed to dry. As the solution dries, the first solvent due to its faster evaporation rate than the second solvent starts to evaporate from the solution, and soon after the first solvent starts to evaporate, the one or more organic polymers, due to its lower solubility in the second solvent, rapidly gels resulting in a substantially uniform organic polymer layer.
