20160048755 | FLOATING-GATE TRANSISTOR ARRAY FOR PERFORMING WEIGHTED SUM COMPUTATION - A weighted sum is a key computation for many neural networks and other machine learning algorithms. Integrated circuit designs that perform a weighted sum are presented. Weights are stored as threshold voltages in an array of flash transistors. By putting the circuits into a well-defined voltage state, the transistors that hold one set of weights will pass current equal to the desired sum. The current flowing through a given transistor is unaffected by operation of remaining transistors in the circuit. | 02-18-2016 |

20140103583 | SYSTEMS AND METHODS FOR FACILITATING THE GENERATION OF CORE-SHEATH TAYLOR CONES IN ELECTROSPINNING - Systems and methods for electrospinning of core-sheath fibers are provided. The systems and methods achieve optimization of a shear stress that exists at a fluid boundary between core and sheath polymer solutions, by varying certain parameters of an electrospinning apparatus and/or the solutions used therewith. | 04-17-2014 |
20140271531 | In-Situ Forming Foam for Endoscopic Lung Volume Reduction - Systems and methods related to polymer foams are generally described. Some embodiments relate to compositions and methods for the preparation of polymer foams, and methods for using the polymer foams. The polymer foams can be applied to a lung at or near an alveolar duct targeted for reduction, occluding the airway and leading to tissue necrosis because the foam prevents oxygenation of the tissue surrounding the duct. In some embodiments, the polymer foams can be formed within a body cavity (i.e., in-situ foam formation). In addition, the foam may form a seal, eliminating the source of air leaks. | 09-18-2014 |
20140271533 | In-Situ Forming Foam for the Treatment of Vascular Dissections - Systems and methods related to polymer foams for the treatment of blood vessel dissections are generally described. Some embodiments relate to compositions and methods for the preparation of polymer foams, and methods for using the polymer foams. The polymer foams can be applied to or within a dissection caused by an intimal tear in a blood vessel, sealing the dissection and preventing further perfusion thereof. In some embodiments, the polymer foam can be formed within a body cavity (i.e., in-situ foam formation). The foam may be used to fill the dissection as a thrombosing agent. In addition, the foam may be used in conjunction with medical devices such as stents, stent-grafts, balloons, and catheters. | 09-18-2014 |
