Patent number: 10310896Abstract: Various embodiments are generally directed to techniques for job flow processing, such as by ordering the performance of parallel tasks in a job flow to minimize a makespan for the job flow, for instance. Some embodiments are particularly directed to ordering the performance of tasks in a job flow based on computation of one or more independent and dependent metrics for tasks in a job flow. In many embodiments, tasks along a critical path of a job flow may be identified and prioritized using the one or more metrics computed for tasks in the job flow. For example, computing a time remaining until end and/or a longest path to end for each task in a job flow may enable a listing of tasks in the job flow to be ordered in a manner that prioritizes tasks to optimize the makespan for the job flow to be executed.Type: GrantFiled: December 13, 2018Date of Patent: June 4, 2019Assignee: SAS INSTITUTE INC.Inventors: John Michael Kichak, Edward L.

Publication number: 20180321077Abstract: A load suspension and weighing system for a removable reservoir unit of a portable dialysis machine includes a centrally located flexure assembly. The flexure assembly includes magnets and a number of flexure rings which allow for movement of the magnets about a fixed circuit board. Sensors in the circuit board sense changes in the magnetic field as the magnets move in relation to the circuit board. The magnetic field changes produce a voltage output which is used by a processor to generate weight calculations. The top of the flexure assembly is attached to the interior of the dialysis machine. The entirety of the reservoir unit is suspended by a first internal frame that is attached to the bottom of the flexure assembly. Having a single flexure assembly positioned above the reservoir unit provides more accurate weight measurements while also preventing damage to the assembly from water spillage.Type: ApplicationFiled: November 9, 2017Publication date: November 8, 2018Inventors: Barry Neil Fulkerson, Joe Fazio, Alec Huang, Brian Thomas Kelly, Tam Nolan, Mark Smith
