Publication number: 20240131268Abstract: A fluid injector system for delivering a multi-phase fluid injection to a patient and methods of fluid delivery is disclosed. Methods of creating and using a multi-aspect fluid path impedance model of the injector system are used. Modeling and adjustment of factors that affect impedance and prevent or reduce backflow, reduce the likelihood of fluid flow rate spikes and provide more accurate flow rates and mixing ratios of fluids may be repeated or happen essentially continuously during an injection. The adjustments may be determined before the injection or determined and/or adjusted during the injection. The determination may include sensor feedback commonly used in injectors such as pressure and position feedback as well as other sensors. In all cases, the user can be notified of adjustments through on-screen notices and/or through the recordation of the injection data by a control device of the injector at the conclusion of the injection.Type: ApplicationFiled: November 27, 2023Publication date: April 25, 2024Inventors: Arthur Uber, III, Chelsea Marsh, William Barone, Michael McDermott, Timothy Newing, Michael Spohn, Vince Delbrugge, Ralph Schriver, Kevin Cowan, David Griffiths

Publication number: 20060032165Abstract: The repair of foundations formed by pouring concrete about a timber post is greatly simplified by the present invention. A post bracket is provided having a first portion that can be inserted into and mechanically restrained in the recess of an existing foundation, for example a foundation wherein a rotted old post has been removed. The post bracket also has second portion to which a new post can be attached. The post bracket is used by clearing out the old post, inserting the first portion and securing the bracket, and then attaching the post. The inventive bracket and method greatly reduce the time and expense construction compared with the prior art method of replacing foundations.Type: ApplicationFiled: August 11, 2004Publication date: February 16, 2006Inventor: Timothy Griffith

Patent number: 5274947Abstract: A novel bait retainer for fish hooks is disclosed which includes a wire type helix with at least one end of the retainer left open and having a sharp point. The body of the retainer is an elongated cylindrical configuration with a diameter and length which corresponds with the type of bait and size of hook with which the retainer is to be used. The retainer is positioned slidably over the shank of the hook with the open end positioned nearest the curved portion of the hook. In use the bait is inserted over the end of the hook and is moved to the shank portion. The retainer is rotatably threaded through the mass or body of the bait and the retainer and bait is then moved backward around the curved portion of the hook until the bait is properly positioned with respect to the barbed end of the hook. In this way the retainer supports the bait and holds the bait in the proper position to catch fish.Type: GrantFiled: August 18, 1992Date of Patent: January 4, 1994Inventor: Timothy Griffiths
