    Abstract: Methods, systems, and apparatus for fabricating a circuit board. The method includes fabricating, using an additive manufacturing device, a trace layer, a sacrificial layer, a rail layer and a lid. The method includes placing the sacrificial layer on the trace layer such that the raised traces protrude through corresponding openings of the sacrificial layer. The method includes depositing a conductive material on top of the sacrificial layer and the plurality of traces. The method includes removing the sacrificial layer from the trace layer and placing the rail layer on the trace layer such that the raised traces align with the corresponding openings of the rail layer. The method includes connecting one or more electrical components and melting a sealing sheet on top of the rail layer and the electrical components to reinforce connections and to provide protection. The method includes placing the lid on top of the sealing sheet.

    Abstract: Apparatuses and methods for harvesting ambient energy involve repeated circuit reconfiguration. An apparatus includes a primary charge storage device, a first secondary charge storage device, a second secondary charge storage device, and switching circuitry. The switching circuitry is configured to cyclically alter connection of the first and second secondary charge storage devices between a series state and a parallel state. First and second moveable electrically conductive elements may include electrically conductive liquid droplets of materials such as water or mercury. At least one of the primary storage device, the first secondary charge storage device, or the second secondary charge storage device includes a capacitance that varies in response to receipt of ambient energy. Concurrently altering relative capacitance and circuit configuration results in exponential growth of harvested energy.

    CPC classification number: G06F8/70

    Abstract: Enabling quick feature delivery is essential for product success and is therefore a goal of software architecture design. But how may we determine if and to what extent an architecture is “good enough” to support feature addition and modification, or determine if a refactoring effort is successful in that features may be added more easily? The applications may use Feature Space and Feature Dependency, derived from a software project's revision history that capture the dependency relations among the features of a system in a feature dependency structure matrix (FDSM), using features as first-class design elements. The applications may also use a Feature Decoupling Level (FDL) metric that may be used to measure the level of independence among features.
