Abstract: Various embodiments are described that relate to energy generation. A housing can retain a spring coupled to a gear set. As the spring experiences linear compression and extension, the spring can cause rotational movement in the gear set. The rotational movement from the gear set can cause rotation of a rotational magnet. The rotational magnet, when rotated about a coil set, can convert an energy. The energy can be used to charge a battery.

Abstract: A multi-compartment mortar increment container (MIC) enables burning of two propellants to broaden the pressure-time curve providing additional energy and force behind a mortar shell while maintaining allowable pressures. During the ballistic cycle, the mortar increment container burns allowing the faster propellant to mix with the slower propellant. The slower propellant will burn later in the ballistic cycle generating higher pressure behind the projectile leading to higher velocity.

Abstract: A battery activation device uses ballistic pressure to directly activate a liquid reserve battery and simultaneously complete the battery ground circuit to the electronics system. The gas pressure generated during ballistic launch reacts upon a piston face that transforms the pressure directly into a linear force which is then applied to the liquid reserve battery for activation. An internal shear disc prevents unintentional battery activation from an accidental drop and if sufficient launch pressure has not been realized by device.

Abstract: A novel filter media includes an array of raised features formed directly on the membrane surface, which create a feed channel. The predetermined configuration of features is dually optimized both for filtration in a first flow direction to maximize unobstructed fluid flow and prevent fouling. The same feature configuration is also optimized for enhancing/increasing turbulence and scouring of the membrane when the flow through the filter is reversed during a cleaning operation. The feature configuration can also be optimized to capture bubbles in reverse flow such that the captured bubbles can be oscillated to further scour the membrane and the features themselves (e.g., in their cavities, etc.).

Abstract: A subspace-based approach to synchrophasor estimation is provided. Embodiments described herein provide two improvements to subspace-based phasor measurement unit (PMU) algorithms based on estimation of signal parameters via rotational invariance techniques (ESPRIT) frequency estimation. The first is a dynamic, real-time thresholding method to determine the size of the signal subspace. This allows for accurate ESPRIT-based frequency estimates of the nominal system frequency as well as the frequencies of any out-of-band interference or harmonic frequencies. Since other frequencies are included in the least squares (LS) estimate, the interference from frequencies other than nominal can be excluded. This results in a near flat estimation error over changes in a) nominal system frequency, b) harmonic distortion, and c) out-of-band interference. Second, the computational burden of ESPRIT is reduced and the proposed algorithm runs in real time on resource-constrained platforms.
