Abstract: 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.

Abstract: A vehicle windshield roller shade including a roller shade assembly having a cylindrical casing, a U-shaped bracket, and a series of fasteners. The cylindrical casing houses a retractable shade hosted on a retractable coil. The U-shaped bracket is configured to be mounted along a vertical side of a windshield using semi-permanent fastening means and is configured to removably engage the cylindrical casing. The series of fasteners may be mounted on an interior surface of the windshield opposing the cylindrical casing and are configured to engage with and secure the retractable shade when the retractable shade is in an extended condition. The retractable shade blocks sunlight from entering a vehicle through its windshield and provides shading to an interior of the vehicle during use.
