Publication number: 20230347109Abstract: Embodiments disclosed herein are directed to an insertion tool (100) for a catheter. The insertion tool (100) engages a proximal end of an introducer (10) and includes a guide channel (106) that aligns with a lumen of the introducer (10). The guide channel (106) supports the catheter (50) to maintain columnar integrity as the catheter (50) is urged distally, past a valve and into the lumen of the introducer (10). In an embodiment, the attachment structure can be inserted past the valve to define a pathway for the catheter. Embodiments also include an elongate opening to allow lateral ingress/egress of the catheter, a segmented cylindrical shape to provide a shortened elongate opening, and an offset elongate opening to allow a rolling introduction of the catheter to the guide channel to prevent abrasion of any coatings disposed on the catheter.Type: ApplicationFiled: January 15, 2021Publication date: November 2, 2023Inventors: Brian Zimmer, Jonathan Darley

Patent number: 11409597Abstract: An error reporting system utilizes a parity checker to receive data results from execution of an original instruction and a parity bit for the data. A decoder receives an error correcting code (ECC) for data resulting from execution of a shadow instruction of the original instruction, and data error correction is initiated on the original instruction result on condition of a mismatch between the parity bit and the original instruction result, and the decoder asserting a correctable error in the original instruction result.Type: GrantFiled: March 6, 2020Date of Patent: August 9, 2022Assignee: NVIDIA Corp.Inventors: Michael Sullivan, Siva Hari, Brian Zimmer, Timothy Tsai, Stephen W. Keckler

Patent number: 9627021Abstract: An 8-transistor SRAM (static random access memory) storage cell provides differential read bit lines that are precharged to a low voltage level for read operations. The 8-transistor storage cell provides separate ports for read and write operations, including differential read bit lines. Prior to each read operation, the differential read bit lines are precharged to the low voltage level. During read operations, one of the two differential read bit lines is pulled high towards a high voltage level while the complementary bit line remains at the low voltage level resulting from the precharge. The difference in voltage between the differential read bit lines is sensed to determine the value stored in each 8-transistor SRAM storage cell and complete the read operation.Type: GrantFiled: October 9, 2012Date of Patent: April 18, 2017Assignee: NVIDIA CorporationInventors: John W. Poulton, Brian Zimmer
