    • The present disclosure relates to using windowing to reduce the bandwidth of an amplitude modulation (AM) power supply input signal (PSIS), which is fed to an AM power supply to provide envelope power to an RF power amplifier stage via an AM power supply output signal. By reducing the bandwidth, noise levels from the AM power supply may be reduced. However, although the bandwidth of the AM PSIS is reduced, the AM power supply output signal may track the AM of the RF power amplifier stage closely enough to meet linearity requirements and to provide high efficiency. The windowing may be based on dividing a stream of AM input samples into a stream of input windows, from which a stream of output windows is created to provide a stream of windowed AM input samples that are used to provide a windowed AM PSIS to the AM power supply.
    • 本公开涉及使用窗口来降低幅度调制(AM)电源输入信号(PSIS)的带宽,其被馈送到AM电源以经由AM电源输出向RF功率放大器级提供包络功率 信号。 通过降低带宽,AM电源的噪声水平可能会降低。 然而,尽管AM PSIS的带宽减小,AM电源输出信号可以跟踪RF功率放大器级的AM足够紧密以满足线性要求并提供高效率。 窗口可以基于将AM输入样本流划分成输入窗口流,从该流输入窗口的流被创建以提供用于向AM提供窗口AM PSIS的窗口AM输入样本流 电源。

    • A method and apparatus are provided for dynamically routing a plurality of simultaneous point-to-point communications through an array of repeating transceivers. Each repeating transceiver may simultaneously act as each of a transmitter of origin for one communication, a final receiver for a second communication, and a repeater for a plurality of other communications. When acting as a repeater, each transceiver applies programmed delays to information before re-transmitting, and these delays are programmed so as to route a communication through the array of transceivers along a designed path along which multiple re-transmissions from local repeating transceivers are received, aligned in time for constructive reinforcement, and retransmitted after dynamically programmable time delays.

    • A system for secure information storage and delivery includes a vault repository that includes a secure vault associated with a user, wherein the secure vault is associated with a service level including at least one of a data type or a data size limit associated with the secure vault, the secure vault being adapted to receive and at least one data entry and securely store the at least one data entry if the at least one of a size or a type of the at least one data entry is consistent with the service level. A mobile vault server coupled to the vault repository creates a mobile vault on a mobile device based on the secure vault and is capable of authenticating the mobile device based on user authentication information. The mobile vault server includes a mobile device handler that communicates with the mobile device. A synchronization utility determines whether the at least one data entry on the secure vault is transferable to or storable on the mobile vault based on at least one of the size or the type of the at least one data entry and transfers the at least one data entry from the secure vault to a corresponding data entry on the mobile vault if the at least one data entry on the secure vault is determined to be transferable to or storable on the mobile vault.
