A method of power management to be implemented by an energy-consuming device includes the steps of: while the energy-consuming device is in an operating state, receiving an input associated with a time period; determining first energy consumption for operation in the operating state for the time period; determining second energy consumption for switching to a shutdown state; determining a smaller one between the first and second energy consumptions; maintaining operation in the operating state when it is determined that the first energy consumption is the smaller one; and switching to the shutdown state when it is determined that the second energy consumption is the smaller one.

This invention proposes using a feed forward quasi universal converter for energy harvesters, and uses it to power IoTs (Internet of things). A typical DC to DC converter uses voltage feedback control or current feedback control. It is not easy for the input impedance to closely match the output impedance of the power source. In the meantime, it also meets its output voltage and power targets. The Feed forward Quasi Universal Converter proposed in this invention controls the input impedance and the output voltage/power within a range that meets the design targets. It is also achieved with a simple electronic adjustment when the source impedance changes or the output requirements change. It has the potential to shorten the IoTs system industrys product development cycle, reduce installation and maintenance costs and facilitate the adoption of hybrid energy sources.

Ever since its discovery the notion of Berry phase has permeated through all branches of physics. Over the past three decades it was gradually realized that the Berry phase of the electronic wave function can have a profound effect on material properties and is responsible for a spectrum of phenomena, such as polarization, orbital magnetism, various (quantum, anomalous, or spin) Hall effects, and quantum charge pumping. This progress is summarized in a pedagogical manner in this review. A brief summary of necessary background is given and a detailed discussion of the Berry phase effect in a variety of solid-state applications. A common thread of the review is the semiclassical formulation of electron dynamics, which is a versatile tool in the study of electron dynamics in the presence of electromagnetic fields and more general perturbations. Finally, a requantization method is demonstrated that converts a semiclassical theory to an effective quantum theory. It is clear that the Berry phase should be added as an essential ingredient to our understanding of basic material properties. © 2010 The American Physical Society.
