摘要： Systems and methods may provide for an energy harvester to power a mobile device. The energy harvester may include an energy harvesting portion to generate electrical power. At least one sensor may measure an environmental condition relating to generation of electrical power by the energy harvesting portion. A controller may generate a signal based on the measured environmental condition by the at least one sensor to the mobile device. Alternatively the signals from the at least one sensor are place in a memory on the energy harvester. In one example, the controller determines the power generated by the energy harvester and the controller signal includes this power information.

摘要： Methods and apparatus relating to reducing switching noise and improving transient response in voltage regulators are described. In an embodiment, one or more pulses are inserted into an output waveform of a voltage regulator. The one or more pulses introduce multiple frequencies into the output waveform of the voltage regulator (e.g., to reduce acoustic noise). In another embodiment, the output voltage of a voltage regulator is modified in response to comparison of the output voltage with at least one of a plurality of threshold values. The plurality of threshold values includes an upper trigger point voltage value and a lower trigger point voltage value. Other embodiments are also disclosed and claimed.

摘要： Methods and apparatus relating to controlling the supply of power to computing devices with dynamically variable energy capacity are described. In one embodiment, logic causes modification to supply of power from a power source to one or more loads in response to a comparison of an output of the power source and a threshold value. The output of the power source may vary over a time period (e.g., oscillating) that causes the one or more loads to become inoperational. Other embodiments are also disclosed and claimed.

摘要： Methods and apparatus relating to low cost and/or low overhead serial interface for power management and other IC (Integrated Circuit) devices are described. In an embodiment, a unique address is assigned to each of a plurality of slave devices. The plurality of slave devices are coupled in a daisy chain configuration. And, any access directed at a first slave device from the plurality of slave devices is allowed based at least in part on comparison of an address of the first slave device and an address associated with the access. Other embodiments are also disclosed and claimed.

摘要： The disclosure generally relates to methods, system and apparatus to wirelessly charge a mobile device using one of conventional or alternative power sources. In an exemplary embodiment, the disclosure provides a method and apparatus to detect power source as a function of its power profile linearity. Once determination is made as to whether the incoming power is harvested from natural resources or is provided from conventional AC/DC adapter/DC source, the incoming power is conditioned and impedance-matched to wirelessly energize an external load. The external load may be a device configured for wireless charging.
