    • Solar power tracking techniques are described herein. In one aspect of the invention, a solar power tracking apparatus includes, but is not limited to, a voltage converter and a controller coupled to the voltage converter. The voltage converter includes an input capable of being coupled to a solar power source and an output capable of being coupled to an electronic load, such as, for example, a portable electronic device. The voltage converter is configured to monitor or detect an amount of power drawn by the electronic load at the output of the voltage converter. In response to the monitored power drawn, the controller is configured to control the voltage converter to reduce amount of power to be drawn subsequently if the monitored amount of power exceeds a predetermined threshold. As a result, the output voltage from the solar power source is maintained within a predetermined range. Other methods and apparatuses are also described.
    • 本文描述了太阳能跟踪技术。 在本发明的一个方面,一种太阳能发电跟踪装置包括但不限于与电压转换器耦合的电压转换器和控制器。 电压转换器包括能够耦合到太阳能电源的输入端和能够耦合到例如便携式电子设备的电子负载的输出端。 电压转换器被配置为监视或检测在电压转换器的输出处由电子负载拉出的功率量。 响应于所监视的电力消耗,控制器被配置为如果监视的功率量超过预定阈值,则控制电压转换器以减少随后抽取的功率量。 结果,来自太阳能电源的输出电压保持在预定范围内。 还描述了其它方法和装置。

    • A modified Series A universal serial bus (USB) receptacle connector is equipped with the functionality to allow the electronic system in which it resides to be configured either as a host device or a peripheral device. The modified USB Series A receptacle connector, according to one embodiment of the invention may include a mechanism such as an additional pin or a mechanical switch to detect the presence of a standard USB Series A plug being inserted into it. Upon detection of a plug, an algorithm may allow the system to determine whether it is to act as a host device or a peripheral device and to determine which device supplies power.
    • 经修改的A系列通用串行总线(USB)插座连接器配备有使其驻留的电子系统配置为主机设备或外围设备的功能。 根据本发明的一个实施例的改进的USB系列A插座连接器可以包括诸如附加引脚或机械开关的机构,以检测插入其中的标准USB A系列插头的存在。 在检测到插头时,算法可以允许系统确定其是否用作主机设备或外围设备,并且确定哪个设备供电。
