  • Patent number: 10278131
    Abstract: An embodiment of the present invention is directed to a method for partitioning an energy or power source. The energy source may be, for example, a battery or batteries or other power supply or power supplies for an electronic device, such as a cell phone, or mobile device. The energy source (battery for example), or power supply, provides power to a cell phone, or mobile device or any other load or power consuming device. Partitioning this energy source is a technique for controlling its operation so that power is provided to the power consuming device, such as a cell phone more efficiently, thereby extending the length of time the phone can be used between re-charging.

  • Publication number: 20180013454
    Abstract: An apparatus, system, and method are provided for energy conversion. For example, the apparatus can include a trans-impedance node, a reactive element, and a trans-impedance circuit. The reactive element can be configured to transfer energy to the trans-impedance node. The trans-impedance circuit can be configured to receive one or more control signals and to dynamically adjust an impedance of the trans-impedance node. The trans-impedance node, as a result, can operate as an RF power switching supply based on the one or more control signals.

  • Patent number: 9768733
    Abstract: Methods and systems for vector combining power amplification are disclosed herein. In one embodiment, a plurality of signals are individually amplified, then summed to form a desired time-varying complex envelope signal. Phase and/or frequency characteristics of one or more of the signals are controlled to provide the desired phase, frequency, and/or amplitude characteristics of the desired time-varying complex envelope signal. In another embodiment, a time-varying complex envelope signal is decomposed into a plurality of constant envelope constituent signals. The constituent signals are amplified equally or substantially equally, and then summed to construct an amplified version of the original time-varying envelope signal. Embodiments also perform frequency up-conversion.
