Abstract: A fuel system including a fuel metering unit, a heat exchanger, a plurality of fuel nozzles, and a coke filtration system. The fuel metering unit is configured to meter a flow of a hydrocarbon fuel. The heat exchanger is fluidly connected to the fuel metering unit. The heat exchanger is configured to heat the hydrocarbon fuel to improve engine performance or efficiency. The plurality of fuel nozzles is fluidly connected to the heat exchanger downstream of the heat exchanger to receive the hydrocarbon fuel heated by the heat exchanger. The coke filtration system includes at least one filter to remove coke particles in the heated fuel. The coke filtration system is located upstream of the plurality of fuel nozzles and directly downstream of the heat exchanger.

Abstract: Various embodiments are directed to a method of driving an end effector coupled to an ultrasonic drive system of a surgical instrument. The method comprises generating at least one electrical signal. The at least one electrical signal is monitored against a first set of logic conditions. A first response is triggered when the first set of logic conditions is met. A parameter is determined from the at least one electrical signal.

Abstract: A method for determining motional branch current in an ultrasonic transducer of an ultrasonic surgical device over multiple frequencies of a transducer drive signal. The method may comprise, at each of a plurality of frequencies of the transducer drive signal, oversampling a current and voltage of the transducer drive signal, receiving, by a processor, the current and voltage samples, and determining, by the processor, the motional branch current based on the current and voltage samples, a static capacitance of the ultrasonic transducer and the frequency of the transducer drive signal.

Abstract: Various embodiments of the present technology are generally related to a multimedia distraction system for patients receiving external beam radiation therapy. More specifically, some embodiments relate to a system for providing a video image to a patient while undergoing a treatment to avoid the need to anesthetize. The system comprises a video image source, a projector communicatively coupled to the video image source, abeam expander coupled to the projector, and a screen transparent to the radiation beam used in a radiation therapy treatment. The present technology can be used to distract a patient during multiple types of external beam radiation therapy including three-dimensional conformal radiation therapy, intensity-modulated radiation therapy, volumetric modulated arc therapy, and non-coplanar arcs, without interfering with the treatment.

Abstract: A floatation system for a marine vessel with a starboard pontoon, a port pontoon, and a center pontoon positioned therebetween. Outer strakes each extending along an outer length between forward and aft ends, each having an outer surface at an outer angle from a horizontal plane and an inner surface at an inner angle from the horizontal plane, and each being coupled to one of the starboard pontoon and the port pontoon. Inner strakes each extending along an inner length between forward and aft ends, each having an outer surface at an outer angle from a horizontal plane and an inner surface at an inner angle from the horizontal plane, and each being coupled to the center pontoon. The outer angles of the inner strakes are greater than the outer angles of the outer strakes and the inner angles of the inner strakes are less than 90°.
