  • Publication number: 20240115259
    Abstract: An apparatus includes a first jaw (16) and a second jaw (618, 718, 900) that cooperate to clamp and staple tissue (90). The second jaw includes a jaw body (620, 720, 902) and a distal tip (619, 719, 906) pivotable relative to the jaw body between a first discrete and a second discrete position. First and second openings (663, 784, 785, 932, 934) are both defined by one of the distal tip or a structure (621, 920) located proximal to the distal tip. A projection (637, 781, 918) is defined by the other of the distal tip or the structure. The projection is positionable within the first opening (663, 785, 932) to releasably retain the distal tip in the first discrete position, and within the second opening (663, 784, 934) to releasably retain the distal tip in the second discrete position.

  • Patent number: 11946225
    Abstract: One embodiment of a hydraulic system for a machine has a first hydraulic circuit including a first pump coupled to a first hydraulic actuator configured to move a first implement of the machine. A second hydraulic circuit includes a second pump coupled to a second hydraulic actuator configured to move a second implement. An electric motor mechanically couples to the first pump and to the second pump. An operator interface receives input from an operator requesting movement of the first and second implements. A controller communicatively coupled to the electric motor and to the operator interface determines, based on the requested movement of the first and second implements respectively, first and second flow allocations respectively for the first and second pumps and determines respective target displacements for the first and second pumps.

  • Patent number: 9665388
    Abstract: A method, system and computer program product for selecting hypervisor platforms that are best suited to process application workloads. Attribute requirements for an application workload, such as high CPU capacity, high power and low cost, are received. A ranking algorithm is then applied to a list of pools of compute nodes to identify an ordered list of pools of compute nodes that are best suited for satisfying the attribute requirements of the application workload by comparing hypervisor characteristics of the pools of compute nodes with the attribute requirements of the application workload. Each pool of compute nodes runs on a particular hypervisor platform which has a unique combination of characteristics that correspond to a combination of a set of attribute requirements (e.g., medium CPU/memory/disk capacity; high CPU and memory performance). In this manner, the hypervisor platforms that are best suited for satisfying the application workload requirements are identified.

  • Publication number: 20160344657
    Abstract: Embodiments of the invention relate to a primary system instance to operate as a foreground process and creation of one or more shadow system instances to operate as a background process. The background instances yield information and performance data. Performance data associated with the foreground and background processes are generated and compared. One of the background instances may be converted to a new primary system instance as an alternative instance configuration.
