Patent number: 12605535Abstract: The circulation assist devices disclosed herein can be used, for example, in methods of decreasing venous pressure in the Fontan circulation. The devices can include an inlet, an outlet, a stator, a rotor, and an impeller driven by rotation of the rotor. In some embodiments, the impeller blade (or blades) can at least partially define a central lumen extending through the device. The device can be coupled to the inferior vena cava and the pulmonary artery. Rotating the impeller blade(s) increases blood velocity through the lumen and causes the outlet pressure to be higher than the inlet pressure. The impeller can be configured such that, when it is stationary, the forward static pressure drop between the inlet and the outlet is minimized. That is, the forward static pressure drop of the device approximates the pressure drop between the inferior vena cava and central pulmonary artery of the unassisted Fontan circulation.Type: GrantFiled: December 28, 2020Date of Patent: April 21, 2026Assignee: Children's National Medical CenterInventors: Pranava Sinha, William A.

Publication number: 20260084089Abstract: The disclosure relates to a method for controlling a system for separating carbon dioxide from the ambient air. The method distinguishes between normal operation, in which carbon dioxide is separated from the ambient air, and special operation, which is not primarily used to separate carbon dioxide. Normal operation comprises conveying a stream of air of ambient air into a first process space of the system, wherein the stream of air is dried in the first process space. The dried stream of air of the ambient air is conducted from the first process space into a second process space, in which adsorption and subsequent desorption of carbon dioxide takes place. In the special operation mode, which takes place before or after normal operation, the system is operated with operating parameters that deviate from normal operation.Type: ApplicationFiled: May 2, 2025Publication date: March 26, 2026Applicants: Volkswagen Aktiengesellschaft, EVERLLENCE SEInventors: Christian HEIMERMANN, Marcel WIEGEL, Peter KAWELKE, Martin HOFER, Klaus BEHNKE, Stephan WEBER, Holger BUSCHMANN

The method comprises conveying a stream of air of the ambient air into a first process space, wherein the stream of air is dried in the first process space, conducting the dried ambient air from the first process space to a second process space, adsorbing carbon dioxide from the dried stream of air with a sorbent material in the second process space, desorbing the carbon dioxide adsorbed in the sorbent material, and storing the desorbed carbon dioxide in a storage unit or transferring the carbon dioxide to a subsequent process. It is provided that the process parameters of the system for drying, adsorption and/or desorption are adjusted on the basis of a degree of loading of the drying agent or the sorbent material.Type: ApplicationFiled: May 2, 2025Publication date: March 26, 2026Applicants: Volkswagen Aktiengesellschaft, EVERLLENCE SEInventors: Christian HEIMERMANN, Marc RUEGGEBERG, Marcel WIEGEL, Peter KAWELKE, Martin HOFER, Klaus BEHNKE, Stephan WEBER

Patent number: 9805158Abstract: A system, method, and computer program product for efficiently finding the best Monte Carlo simulation samples for use as design corners for all design specifications to substitute for a full circuit design verification. Embodiments calculate a corner target value matching an input variation level by modeling the circuit performance with verified accuracy, estimate the corner based on a response surface model such that the corner has the highest probability density (or extrapolation from the worst sample if the model is inaccurate), and verify and/or adjust the corner by performing a small number of additional simulations. Embodiments also estimate the probability that a design already meets the design specifications at a specified variation level. Composite multimodal and non-Gaussian probability distribution functions enhance model accuracy. The extracted design corners may be of particular utility during circuit design iterations.Type: GrantFiled: November 16, 2015Date of Patent: October 31, 2017Assignee: CADENCE DESIGN SYSTEMS, INC.Inventors: Hongzhou Liu, Stephan Weber, Wangyang Zhang
