Abstract: The present invention includes systems and methods for continuous fracturing operations across a multichannel fracturing configuration. To swap a first well for a second well while continuously pumping water and/or frac fluid through the fracturing system, the second well may be initially prepared through a pressure equalization process. Once the second well is equalized and open, the first well may be sequentially closed and depressurized. Thus, the first well is swapped for the second well while the water and/or frac fluid continuously flows through the system. A conditional flow control valve may be used to sequentially open and/or close the flow of frac fluid through the frac manifold.

Abstract: Endovascular variable aortic control catheters (EVACC) are provided that are adapted to augment upstream blood pressure and regulate downstream blood flow for patients in shock. The EVACC devices provide improved treatment for truncal wounds, which may be used for example on a battlefield, thereby increasing survivability of injured soldiers. The devices are a catheter-based system having a proximal hand piece for controlled deployment of the device through a delivery sheath. A collapsible, wire framework supports an expandable and collapsible occlusion barrier. The wire basket and occlusion barrier expand to fit within the lumen of the aorta. Various movable elements are used to adjust an adjustable passageway to regulate controlled anterograde blood flow.

Abstract: A vascular access disassembling needle assembly is provided that enables rapid insertion of a guide wire into the needle and subsequent rapid removal of the access needle off the guide wire by facile disassembly of the needle. The disassembling needle assembly includes a needle portion wherein the needle breaks apart by splitting along at least one seam that extends from the proximal to the distal end to allow removal of the guide wire. Various mechanical features are described that can facilitate the separation of the needle body along at least one seam. Once one or more seams are separated, the needle body may be removed from the guide wire without the need to withdraw the needle along the length of the guide wire, which permits preloading of expanders and other medical devices onto the guidewire.

Abstract: The present disclosure provides a method and device for dynamic recognition of emotion based on facial muscle movement monitoring, including: obtaining muscle movement data on one side and continuous frame images on the other side; obtaining multiple emotional states related to emotions, associating each emotional state with its corresponding continuous frame images, associating each emotional state with the muscle movement data corresponding to the continuous frame images at the same location and at the same time, to form a training set, building an emotion recognition model; inputting the muscle movement data and continuous frame images obtained in real time into the emotion recognition model to obtain a corresponding emotional state. This method builds an emotion recognition model through muscle movement data and continuous frame image, and uses motion data to make up for the parts of small action images that cannot be collected, thereby obtaining accurate emotion detection results.

Abstract: A method for triggering switches in a defined order comprises providing two or more PCSS devices and a compatible optical trigger; projecting a beam from the optical trigger; splitting the optical beam into two or more paths toward the two or more PCSS devices, wherein each of the two or more paths has a different length such that each of the two or more PCSS devices are triggered with defined time differentials.

The optical path consists of at least one of an optical fiber, a mirror arrangement, and a lens arrangement. Path lengths may be controlled by different fiber lengths, and transmitting a beam through a solid having a higher index of refraction than other beam path(s).

Abstract: A method for data communication between a first node and a second node includes forming one or more redundancy messages from data messages at the first node using an error correcting code and transmitting first messages from the first node to the second node over a data path, the transmitted first messages including the data messages and the one or more redundancy messages. Second messages are received at the first node from the second node, which are indicative of: (i) a rate of arrival at the second node of the first messages, and (ii) successful and unsuccessful delivery of the first messages. A transmission rate limit and a window size are maintained according to the received second messages. Transmission of additional messages from the first node to the second node is limited according to the maintained transmission rate limit and window size.

Abstract: A scramjet engine with a novel isolator is disclosed herein. The scramjet includes an air inlet configured to receive and direct air into the engine and a combustor operable to receive air from the air inlet and combust fuel therein as is conventional. An isolator is positioned between the air inlet and the combustor. The isolator includes a primary flow path separated into a plurality of separate secondary flow channels formed therethrough. The smaller secondary flow channels prevent shockwaves from propagating upstream from the combustor to the inlet that can occur during some operating conditions of a supersonic combustion flow process.

Abstract: The present invention relates to a solid-state battery that is based on a phthalocyanine solid-state electrolyte/anode connection that is chemically obtained. Such chemical connection process yields a solid electrolyte interphase that connects the solid-state battery's phthalocyanine solid-state electrolyte and anode. Unlike other processes for forming solid-state electrolyte/anode connections, the present chemical process does not require that solid-state electrolyte be ductile and flow under high pressure.

Abstract: The present application discloses a new form of ?-STAP, referred to herein as post ?-STAP or P?-STAP, which overcomes the drawbacks associated with existing ?-STAP techniques. The P?-STAP techniques described herein facilitate the generation of additional training data and homogenization after pulse compression. For example, P?-STAP techniques may apply a plurality of homogenization filters to a pulse compressed datacube generated from an input radar waveform, which produces a plurality of new pulse compressed datacubes with improved characteristics. Unlike existing ?-STAP techniques described above, which require pre-pulse compressed data to operate, the P?-STAP techniques disclosed in the present application are designed to utilize pulse compressed data, and therefore may be readily applied to legacy radar systems.

Abstract: A galvanic isolator circuit and method provide for galvanically isolating and current limiting a power source from a load. A direct current (DC) input voltage (“vin”) and an input current (“iin”) are received. A full- or half-bridge rectifier is switched to synthesize a first alternating voltage waveform that magnetically couples through a transformer to induce a second alternating voltage waveform with galvanic isolation from the first alternating voltage waveform, preventing potentially-faulted load from a source. The second alternating voltage waveform is rectified to produce a direct current (DC) output voltage (“vo”) having output current (“io”) through more than one drive transistor or diode. The more than one primary-side drive transistor is current limited to reduce or prevent brown-out, black-out, or protective race conditions in the non-faulted portions of DC power generation systems and DC distribution electrical power systems.
