Abstract: A mover for an independent cart system includes a drive member for a linear drive system, a power source configured to supply electrical power to at least one device mounted on the mover, and a mounting plate secured to the mover. The mounting plate is configured to selectively receive one of multiple fixtures. The mounting plate includes at least one electrical connector configured to engage a complementary electrical connector on each of the fixtures, at least one connector configured to engage a complementary connector on each of the fixtures to positively retain each of the fixtures to the mounting plate, and a control circuit operative to either transfer at least one control signal to or receive at least one feedback signal from each of the fixtures.

Abstract: Disclosed aspects relate to sunder management with respect to a shared pool of configurable computing resources having a cluster of disperse nodes. A set of sunder event response prioritization data may be determined based on a set of cluster profile data for the cluster of disperse nodes. A sunder event which indicates a partitioned status may be detected with respect to the cluster of disperse nodes. The set of sunder event response prioritization data may be examined. In response to detecting the sunder event, a sunder event response operation may be performed to maintain asset availability.

Abstract: Methods and systems are for analyzing and measuring cyber risk using analytical approaches to determine and measure the consequences and/or vulnerabilities to a system (e.g., a computer network, an enterprise network, etc.) due to cyber incidents. By evaluating and quantifying risks associated with several types of cyber incidents and/or security breaches based on a network architecture and/or system design, the cyber risk analysis tool may enable the enterprise leadership to make prudent, informed decisions on how to address individual cyber risks (e.g., determine risk policy) and/or modify existing network deployments or policies. For many institutions, enterprise objective is defined in financial terms, such as budget impact, corporate earnings, impact to balance sheet and/or reputation impact. Thus, the output of the cyber risk analysis tool may be converted to or otherwise expressed as a financial cost in order to provide useful information to decision makers.

Abstract: A quorum service detects liveness failures of at least two failed nodes in a domain of a cluster infrastructure layer of a cluster environment within a limited time frame and adds the at least two failed nodes to a list of nodes set to pending to be fenced by a group leader node. The quorum service determines whether the at least two failed nodes include the group leader node. The quorum service, responsive to the at least two failed nodes not including the group leader node, triggers the group leader node to trigger at least one fencing operation to fence the at least two failed nodes in the list of nodes. The quorum service, responsive to the at least two failed nodes including the group leader node, sets a new node as the group leader node and triggers the new node set as the group leader node to trigger the at least one fencing operation to fence the at least two failed nodes in the list of nodes.

Abstract: A system to improve communication security in cluster machine processing may include interconnected computers that can jointly process data. The system may also include a shared secret key used by each of the interconnected computers to encrypt, decrypt, and/or authenticate data being sent, or received, from one of the interconnected computers to another of the interconnected computers. The system may further include a new shared secret key used by each of the interconnected computers to encrypt, decrypt, and/or authenticate data being sent, or received, from one of the interconnected computers to another of the interconnected computers. In addition, the new shared secret key may coexist with the shared secret key without adversely affecting the joint processing of data performed by the plurality of interconnected computers.

Abstract: A quorum service within a cluster infrastructure layer of a cluster environment comprising a plurality of nodes automatically triggers at least one automated fencing operation integrated within the quorum service, to reliably maintain a node usability state of each node of the plurality of nodes indicating an availability of each node to control and access at least one shared resource of the cluster. The quorum service reports the node usability state of each node as a cluster health status to at least one distributed application within an application layer of the cluster environment, to provide a reliable cluster health status of the plurality of nodes to the at least one distributed application for a failover of said at least one shared resource from control by a failed node from among the plurality of nodes to another node from among the plurality of nodes.

Abstract: A method for managing node-specific quorum roles in a cluster of nodes. The method comprises assigning a configuration change of node role attributes to a node in the cluster, with each attribute being represented by a bit of a binary value. The binary value corresponding to the specified node role attributes is converted to an integer value and the integer value is stored in a node record associated with the node. The node record is accessed to isolate each bit of the integer value associated with the node and the node role attributes assigned to the node are identified from each of the isolated bits of the integer value associated with the node. A determination of whether the configuration change can be safely supported by a configuration quorum of nodes required to represent the cluster's configuration accurately is made based on the identified node role attributes.

Abstract: A new and distinct cultivar of Sarracenia called ‘Redbug’ is described that is a vigorously growing, compact plant having dark Chrysanthemum Crimson (H.C.C. #860/2) pitchers, suffused with veins of a deeper cast of Chrysanthemum Crimson. The pitcher is distinguished from other Sarracenia by having a higher width-to-length ratio, a wider hood, and a prominent horizontal filament. Furthermore, in the winter the leaves retain color and texture and are hardy to United States Department of Agriculture Hardiness Zone 6.

Abstract: A new and distinct cultvar of Sarracenia called ‘Redbug’ is described that is a vigorously growing, compact plant having pubescent dark Chrysanthemum Crimson (H.C.C. #824) pitchers, suffused with veins of a deeper cast of Chrysanthemum Crimson. The pitcher is distinguished from other Sarracenia by having a higher width-to-length ratio, a wider hood, and a prominent horizontal filament. Furthermore, in the winter the leaves retain color and texture when grown outdoors in United States Department of Agriculture Hardiness Zone 8 or warmer (minimum winter temperature to 10° F.).
