Abstract:

An epoxy composition includes an epoxy resin, a latent curing agent, and a catalyst. The composition includes two epoxide groups per molecule, and the latent curing agent is preferably a dicyanopolyamide, and most preferably dicyandiamide. The catalyst includes 2,4-toluene bis dimethyl urea, preferably in a concentration exceeding 70% by weight. The composition can be used in prepregs. The relative concentrations of the epoxy resin, curing agent, and catalyst are selected to achieve desired properties, including specific curing times and temperatures, and glass transition temperatures that enable a cured resin composition to be removed from a mold after being heated to its curing temperature, without being cooled. Exemplary formulations have reduced cure times, at both high and low curing temperatures, as compared to prior art formulations.

US Classification:

712215, 717150

Abstract:

A method for improving parallel processing of computer programs. DOACROSS loops and similar code are identified and parallelized using a post-wait control structure. The post-wait control structure may be implemented to include any one of a single counter to enforce an order of execution, an array to track code completion that is indexed by a modulus of a positive integer number, and/or a set of arrays to track a last code completed by a thread and a current code being executed by a thread.

US Classification:

4352885, 435 29

Abstract:

A polymeric chip having at least one three-dimensional porous scaffold, a microfluidic channel inlet to the porous scaffold, and a microfluidic channel outlet from the porous scaffold. In one embodiment, the polymeric chip has two three-dimensional porous scaffolds: one scaffold comprises liver cells and the other scaffold comprises cancer cells. The chip can be used as a multi-organ tissue model system.

US Classification:

381191, 310334, 367153

Abstract:

Systems and methods which improve the directivity of a transducer array by reducing electrical cross-talk between conductors connected to individual transducer array elements through the use of a plurality of interconnect circuits are shown. A plurality of signal transmission path circuits, such as circuit boards, flexible printed circuits, etc. , are used to provide electrical power to and receive signals from transducer elements of a transducer array. Embodiments couple transducer elements to conductive traces of the signal transmission path circuits in a manner such that adjacent transducer elements are not connected to conductive traces on the same signal transmission path circuit. In some embodiments, a plurality of signal transmission path circuits are offset such that two identical signal transmission path circuits can be used to provide connectivity to array transducer elements using more widely spaced conductive traces, thus reducing electrical cross-talk effects.

International Classification:

A61B 8/00

US Classification:

600438, 600437

Abstract:

Ultrasound imaging is synchronized with measurements. Generating three-dimensional representations is synchronized with measuring one or more parameters. For example, measurements are preformed based on navigating through a volume. The measurements are linked to the corresponding three-dimensional representations. As another example, the user selects a measurement from a graph. A three-dimensional representation of the volume associated with the selected measurement is presented.

International Classification:

B01F 5/00

US Classification:

366340, 366336

Abstract:

A micromixer is fabricated using a selective high intensity focused ultrasound foaming technique. The micromixer employs a 3D porous region for effective mixing. The 3D porous micromixer can achieve sufficient mixing results with a short mixing length for flows with a Reynolds number as low as 0. 1. The fabrication process of the micromixer is rapid, low-cost, and biocompatible. The pore size of the micromixer can be controlled by adjusting the selective high intensity focused ultrasound foaming parameters. The micromixer has potential for use in lab-on-a-chip and micro-total-analysis devices.
