Publication number: 20240123132Abstract: A drain cassette for a dialysis unit has a fluid channel between venous and arterial connection ports, and a valve may controllably open and close fluid communication between a drain outlet port and the venous connection port or the arterial connection port. A blood circuit assembly and drain cassette may be removable from the dialysis unit, e.g., by hand and without the use of tools. A blood circuit assembly may include a single, unitary member that defines portions of a pair of blood pumps, control valves, channels to accurately position flexible tubing for an occluder, an air trap support, and/or other portions of the assembly. A blood circuit assembly engagement device may assist with retaining a blood circuit assembly on the dialysis unit, and/or with removal of the assembly. An actuator may operate a retainer element and an ejector element that interact with the assembly.Type: ApplicationFiled: December 22, 2023Publication date: April 18, 2024Applicant: DEKA Products Limited PartnershipInventors: Kevin L.

Publication number: 20210338274Abstract: A surgical access device assembly. The assembly includes a cannula having a working channel and a helical tissue engagement feature disposed along an outer surface of the cannula and configured to stabilize the cannula relative to a body cavity wall of a patient. The assembly also includes a depth limiter movably coupled with the cannula. The depth limiter includes a body portion extending about a central axis of the depth limiter and including a protrusion extending radially inwardly relative to the central axis. The body portion is movable angularly relative to the cannula between a fine adjustment configuration and a coarse adjustment configuration. In the fine adjustment configuration the protrusion is configured to selectively threadably engage the helical tissue engagement feature. In the coarse adjustment configuration the protrusion is configured to selectively threadably disengage the helical tissue engagement feature such that the depth limiter is translatable axially along the cannula.Type: ApplicationFiled: March 26, 2021Publication date: November 4, 2021Inventors: Gregory G. Scott, Jonathan M. Cepress, David L. Collins, Matthew S. Corbin, Jeffrey L. Savage

Patent number: 8297392Abstract: A hybrid energy management system that estimates the net regenerative energy that can be collected during the breaking action of the swing mechanism, then, since this is the net energy that can be used to recharge an energy storage device without using the engine to help recharge the energy storage device, the system limits the use of the energy storage device to that net amount predicted to be available from the recovery period. The net regenerative energy is calculated by considering motor and inverter efficiencies for transferring energy to the battery and changes in the boom/stick/bucket inertia moment.Type: GrantFiled: September 24, 2010Date of Patent: October 30, 2012Assignee: Caterpillar Inc.Inventors: Benjamin A. Treichel, David L. Collins, Stephen Eric Post

Patent number: 7024550Abstract: The disclosed embodiments relate generally to providing increased data integrity in computer systems and, more particularly, to using a system management processor to overcome a computer system failure because of corrupted programming. A system management processor detects an attempted boot by host computer system and starts a watchdog timer. If the system BIOS or other firmware fails to execute, the watchdog timer expires and the system management processor places the system processor(s) in a reset state. The system management processor provides the address of a back-up BIOS or firmware and releases the system processor(s) from the reset state. The system processor(s) are redirected to the back-up BIOS or firmware and the computer system is able to boot.Type: GrantFiled: June 28, 2002Date of Patent: April 4, 2006Assignee: Hewlett-Packard Development Company, L.P.Inventors: David L. Collins, Steven Ray Dupree

Patent number: 6915393Abstract: The disclosed embodiments relate to a device for generating physical addresses in a multi-processor computer system. The computer system may be adapted to support multiple physical memory partitions. Agent IDs for each of a plurality of processors may be used to correspond with a partition offset, which may be used to define a separate physical memory partition for each processor. The partition offset may be used with a virtual address to form a physical address.Type: GrantFiled: January 7, 2003Date of Patent: July 5, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventors: David L. Collins, Steven Ray Dupree

Patent number: 6889341Abstract: The disclosed embodiments relate generally to providing increased data integrity in computer systems and, more particularly, to using a system management processor to maintain the integrity of stored information. A system management processor detects an attempt to reboot the computer system and holds the system processor or processors in a reset state. While the system processor or processors are held in the reset state, the system management processor checks data such as the system BIOS to identify corruption. If the data checked by the system management processor is not corrupted, the system processor or processors are removed from the reset state and allowed to continue normal operation. If the data checked by the system management processor is corrupted, the system management processor repairs the corrupted data before removing the system processor or processors from the reset state.Type: GrantFiled: June 28, 2002Date of Patent: May 3, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventors: David L. Collins, Steven Ray Dupree
