Patent number: 10941892Abstract: Male and female fittings are configured to mate to form a valved connector system. Some embodiments of the female fitting include movable poppet configured to sealingly engage a flared projection within the female fitting. Some embodiments of the male fitting include a male mating aperture, and a movable plug configured to sealingly engage the male mating aperture. When the female fitting is mated with a male fitting, the male fitting forces the poppet to disengage from the flared projection, and the flared projection forces the plug to recede into the male fitting, to open a fluid path through the valved connector system.Type: GrantFiled: October 20, 2017Date of Patent: March 9, 2021Assignee: Hewlett Packard Enterprise Development LPInventors: Michael Scott, Steven J. Dean, Harvey J. Lunsman

Patent number: 10521260Abstract: A high performance computing (HPC) system has an architecture that separates data paths used by compute nodes exchanging computational data from the data paths used by compute nodes to obtain computational work units and save completed computations. The system enables an improved method of saving checkpoint data, and an improved method of using an analysis of the saved data to assign particular computational work units to particular compute nodes. The system includes a compute fabric and compute nodes that cooperatively perform a computation by mutual communication using the compute fabric. The system also includes a local data fabric that is coupled to the compute nodes, a memory, and a data node. The data node is configured to retrieve data for the computation from an external bulk data storage, and to store its work units in the memory for access by the compute nodes.Type: GrantFiled: July 14, 2017Date of Patent: December 31, 2019Assignee: HEWLETT PACKARD ENTERPRISE DEVELOPMENT LPInventors: Steven J.

Patent number: 7466561Abstract: The system includes a chassis and a printed circuit board (e.g., a motherboard) that is attached to the chassis. The system further includes an actuator that is slidably engaged with the chassis and a cam plate that is rotatably engaged with the chassis. The actuator engages the cam plate such that maneuvering the actuator rotates the cam plate. The system further includes a blade (e.g., an electronic module) which is slidably engaged with the chassis such that the blade slides in a first direction within the chassis as the blade is inserted into the chassis. The blade is inserted into the chassis until the blade engages the cam plate. The cam plate engages the blade such that rotation of the cam plate causes the blade to continue to move in the first direction and engage the printed circuit board.Type: GrantFiled: October 28, 2005Date of Patent: December 16, 2008Assignee: Silicon Graphics, Inc.Inventor: Steven J.
