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: An apparatus for providing virtualization services is presented. According to an exemplary embodiment, the apparatus may include a middle chassis for containing one or more computing components for providing virtualization services, a top chassis for covering the middle chassis, where the top chassis includes a heat sink for conducting thermal energy away from the one or more computing components contained in the middle chassis, and where the top chassis is capable of being securely fastened to the middle chassis. The exemplary embodiment may further include a bottom chassis providing a base for the apparatus and a covering for the bottom of the middle chassis, where the bottom chassis includes a heat sink for conducting thermal energy away from the one or more computing components contained in the middle chassis, and where the bottom chassis is capable of being securely fastened to the middle chassis.

Abstract: A fuel additive having detergency, solubility and thermal stability comprises a detergent component, e.g., polyalkenyl succinimide, and a carrier fluid obtained from a diamondoid fluid comprising an compound selected from the group consisting of adamantane, diamantane, triamantane, tetramantane, and the alkyl-substituted derivatives thereof.
