    • A method and system for reducing thermal load by monitoring and controlling current flow in a portable computing device (“PCD”) are disclosed. The method includes monitoring a temperature of the PCD and determining if the temperature has reached a temperature threshold condition. This temperature threshold condition may be comprised within any one or more of a plurality of thermal policy states, in which each thermal policy state may dictate various thermal mitigation techniques. The thermal policy states may be associated with values that may indicate thermal loading of a PCD. If the temperature has reached the first threshold condition, then electrical current exiting a power supply device may be monitored. If it is determined that the electrical current has exceeded a current threshold condition, such as a maximum current, a hardware device corresponding to the electrical current may be selected for application of a thermal mitigation technique.
    • 公开了一种通过监视和控制便携式计算设备(“PCD”)中的电流来减少热负荷的方法和系统。 该方法包括监测PCD的温度并确定温度是否达到温度阈值条件。 该温度阈值条件可以包括在多个热策略状态中的任何一个或多个中,其中每个热策略状态可以指定各种热缓解技术。 热策略状态可能与可能指示PCD的热负载的值相关联。 如果温度达到第一阈值条件,则可以监视离开电源装置的电流。 如果确定电流已经超过诸如最大电流的电流阈值条件,则可以选择对应于电流的硬件设备来应用热缓解技术。

    • An embodiment of the invention is a predistortion approach to linearize a power amplifier by using one or more analog multiplier(s) and a DSP-based processor. For the analog embodiment, the inherent nature of the analog circuitries allows digital predistortion processing structured directly at the RF band, and enables a single power amplifier to support multi-modulation schemes, multi-carriers and multi-channels. As a result, the predistortion architecture is particularly suitable for wireless transmission systems, such as base-stations, repeaters, and indoor signal coverage systems. The wireless system performance can be improved and upgraded just by using the new PA module rather than change or rebuild new subsystem in existing base station. The analog embodiment can also mix and match its analog multipliers with other analog components such as phase splitters, phase shifters, attenuators, filters, couplers, mixers, low-noise amplifiers, buffers, envelope detectors, and etc., to provide additional features.
    • 本发明的一个实施例是通过使用一个或多个模拟乘法器和基于DSP的处理器对功率放大器进行线性化的预失真方法。 对于模拟实施例,模拟电路的固有特性允许直接在RF频带处构成的数字预失真处理,并且使单个功率放大器能够支持多调制方案,多载波和多信道。 因此,预失真架构特别适用于诸如基站,中继器和室内信号覆盖系统之类的无线传输系统。 无线系统性能可以通过使用新的PA模块来改进和升级,而不是改变或重建现有基站中的新子系统。 模拟实施例还可以将其模拟乘法器与诸如相位分离器,移相器,衰减器,滤波器,耦合器,混频器,低噪声放大器,缓冲器,包络检测器等的其它模拟组件混合并匹配,以提供附加特征。

    • A data interface for transferring digital data between a host and a client over a communication path using packet structures linked together to form a communication protocol for communicating a pre-selected set of digital control and presentation data. The signal protocol is used by link controllers configured to generate, transmit, and receive packets forming the communications protocol, and to form digital data into one or more types of data packets, with at least one residing in the host device and being coupled to the client through the communications path. A maximum operating data rate can be negotiated. The interface provides a cost-effective, low power, bi-directional, high speed data transfer mechanism over a short-range “serial” type data link, which lends itself to implementation with miniature connectors with thin flexible cables which are especially useful in connecting display elements such as wearable micro-displays to portable computers and wireless, communication devices.
