Abstract: The present disclosure is directed to self-synchronizing devices that can connect and self-synchronizes voltage, frequency and phase of two or more power sources. The disclosed embodiments enable a modular power system to serve as the primary or secondary source of power for applications requiring loads from a few kilowatts (kW) to the scale of megawatts (MW). The modular system is generalized to use either a single or multiple power generation sources at once, with the ability to connect and self-synchronize voltage, frequency, and phase of a variety of different types of power sources. Power control systems designed to function with self-synchronizing technology enable a modular power system to satisfy a wide variety of needs, simplifying the existing method of achieving synchronization and enabling new features of resiliency and expandability. The self-synchronization can be implemented into a wide variety of electronics including but not limited to inverters and generator controllers.

Abstract: If an additional power source is introduced at the distribution level it is then possible for power to flow back into the grid. This is a potentially undesired scenario, so much so that some entities enacted laws to regulate/control this scenario. There are also regulations in some places that restricts off-grid scenarios. The present disclosure is directed to embodiments that can operate with the grid, or islanded, with a range of grid load from 0-100%. 10% grid load is described as a model for abiding by legal interconnection/tax requirements. At the interconnection point/points there is typically protection and or control technology such as fuses in a circuit-breaker that limit current to a particular load or loads. A solution to this scenario, using split load configuration according to embodiments of the present disclosure, allows for both distributed generation and no power flow back into the grid.

Abstract: The invention features a fly height measurement system for measuring fly height of a slider over a storage disc. The fly height measuring system includes a source of light, a slider, a detector module and a processor. The source of light produces light along a light path. The slider includes an objective lens positioned such that light from said source hits the objective lens and is directed toward a surface of a disc. Light propagating from the disc is directed to a detector. The processor estimates the fly height of the slider based on detector module output.
