Abstract: In one embodiment, a combustion apparatus comprises: an oxidant inlet, a fuel inlet, a mixing zone configured to mix fuel and oxidant to form a mixture, a combustion zone in fluid communication with the mixing zone and configured to combust the mixture, and an outlet in fluid communication with the combustion zone. The mixing zone, the combustion zone, and/or the outlet comprises an electro-dynamic swirler configured to swirl ionized gas. The electro-dynamic swirler comprises a plurality of electrodes in electrical communication with a power source. In one embodiment, a method of creating thrust comprises: mixing a fuel and an oxidant to form a mixture, igniting the mixture to form an ignited mixture, combusting the ignited mixture to form a flame, and using the flame to create thrust, wherein the flame and/or the fuel and oxidant are electro-dynamically swirled.

Abstract: A card reader device is configured to carry out communication with a contactless readable card according to standard ISO/IEC 14443 type B. In order to provide that a modulation index, which self-adjusts in close range in a presence of a contactless readable card, corresponds to a desired specified modulation index, the magnetic field is received and evaluated via a reception antenna of the card reader device. The modulation index is controlled or regulated accordingly in case of deviations between a measured modulation index and a specified value for the modulation index in order to approximate the measured modulation index to the specified value.

Abstract: A fuel injector is coupled to an engine. The fuel injector includes an injection opening configured to vary in cross-section between a open state and a fully closed state. The fuel injector is configured to provide a plurality of discrete commanded fuel injections into an engine cylinder by modulating the size of the injection opening without completely closing the opening to the fully closed state.

Abstract: A rupture resistant system comprises a tank comprising a top member, a sidewall member, and a bottom member, and a component situated within the tank and susceptible to creating increasing pressure within the tank when under a fault condition. At least one of the top, sidewall, and bottom members is connected to another of the top, sidewall, and bottom members in a manner so as to cause an increase in inner volume of the tank under increased pressure conditions.

Abstract: A system comprises a tank, a radiator connected to the tank, and a component situated within the tank and susceptible to creating increasing pressure within system when under a fault condition. The radiator is configured to directionally vent pressure under excessive pressure conditions.

Abstract: A fuel injector is coupled to an engine. The fuel injector includes an injection opening configured to vary in cross-section between a open state and a fully closed state. The fuel injector is configured to provide a plurality of discrete commanded fuel injections into an engine cylinder by modulating the size of the injection opening without completely closing the opening to the fully closed state.
