Abstract: A method of fabricating cooling features on a CMC component may comprise compressing a fabric preform within tooling including holes and/or recesses facing the fabric preform. During the compression, portions of the fabric preform are pushed into the holes and/or recesses. Gases are delivered through the tooling to deposit a matrix material on exposed surfaces of the fabric preform while the fabric preform is being compressed. The matrix material builds up on the portions of the fabric preform pushed into the holes and/or recesses, and a rigidized preform with surface protrusions is formed. The tooling is removed, and the rigidized preform is densified, thereby forming a CMC component including raised surface features.

Abstract: A method for providing automatic suppression of an alert includes receiving a first error associated with a first dataset, the first dataset being among a plurality of datasets in a computer data environment, accessing dependency data that describes a set of dependencies between the first dataset and other datasets, examining the dependency data to automatically identify a second dataset from among the other datasets, the second dataset being a dataset on which the first dataset depends, accessing alert data for the computer data environment to determine whether an active alert for the second dataset provides an indication that the first error is redundant to a second error associated with the second dataset, and upon determining that the first error is redundant, suppressing transmission of the alert and storing data about suppressing transmission in a data structure.

Abstract: A ceramic matrix composite (CMC) is formed using a three-dimensional (3-D) woven preform by removing the set of sacrificial fibers from the 3-D woven preform and allowing a metal or metal alloy infiltrate the 3-D woven preform. The 3-D woven preform is formed by a method that includes providing a woven layer comprising a first set of ceramic fibers oriented in a first (x) direction woven with a second set of ceramic fibers oriented in a second (y) direction; stacking a plurality of woven layers on top of each other, said woven layers providing a two-dimensional (2-D) preform; weaving a set of sacrificial fibers in a third (z) direction with the 2-D preform, said weaving providing the 3-D woven preform; and shaping the 3-D woven preform into a predetermined shape.

Abstract: Coagulation and fibrinolysis assays and related compositions, systems, methods, and kits are provided. In some embodiments, a coagulation and fibrinolysis assay may utilize one or more biological molecules. For instance, the assay may comprise combining a blood or blood-derived patient sample with the biological molecule(s) and measuring one or more properties of the sample associated with coagulation and/or fibrinolysis. The biological molecules may serve to shorten the assay duration and/or enhance the sensitivity of the assay relative to certain conventional assays. In certain embodiments, the biological molecules may allow pathological coagulation and/or fibrinolysis phenotypes to be elucidated. The coagulation and fibrinolysis assays described herein may be used for a wide variety of clinical and/or laboratory applications, including the diagnosis of certain coagulation and/or fibrinolysis disorders, such as trauma-induced coagulopathy and hyperfibrinolysis.

Abstract: A system is provided for controlling the flow of data-packet traffic through an Ethernet telecommunications network having a multiplicity of nodes interconnected by multiple network links. Incoming data-packet traffic from multiple customer connections are received at a first node for entry into the network via the first node. Flow control messages are generated to represent the states of the first node and, optionally, one or more network nodes upstream from the first node, and these states are used as factors in controlling the rate at which the incoming packets are admitted to the network. Alternatively, the flow control messages may be used to control the rate at which packets generated by a client application are transmitted to the first node.

Abstract: A method of utilizing a node power architecture (NPA) system, the method includes receiving a request to create a client, determining whether a resource is compatible with the request, and returning a client handle when the resource is compatible with the request.

Abstract: A telecommunications system includes a network for transporting packets on a path between selected subscriber end points. The network has multiple nodes connected by links, with each node (a) pairing the forward and backward paths of a connection and (b) allowing for the injection of messages in the backward direction of a connection from any node in the path without needing to consult a higher OSI layer. A system is also provided for protecting connection paths for transporting data packets through an Ethernet telecommunications network having a multiplicity of nodes interconnected by a multiplicity of links. Primary and backup paths are provided through the network for each of multiple connections, with each path including multiple links.

The circuit board slot has first connectors for receiving mating second connectors on the circuit boards, and multiple circuit board guides for guiding and securing horizontal circuit boards inserted into the slot. Adjacent pairs of the guides are spaced to receive circuit boards of predetermined widths, and at least one of the guides is removable so that it can be re-positioned within the slot for changing the spacing between adjacent pairs of the guides to receive circuit boards of different widths. The circuit boards may be telecommunication line cards.

Abstract: A method of fault notification in a carrier Ethernet having the capability of generating and transmitting OAM packets having flag fields, comprises inserting a bit in one of the flag fields to indicate the presence of service-affecting information in the OAM packets, detecting the presence of the inserted bit at the end of a data path, and performing a service protection action in response to the detection of the inserted bit prior to parsing the information in the message. One type of service protection action is protection switching.
