    • A system and method for securing a portable consumer device is disclosed. One embodiment of the present invention may be directed to a security system comprising a first wireless apparatus for use with a mobile communication device and a second wireless apparatus configured to removably and electrically couple to the mobile communication device. The second wireless apparatus comprising a second processor, a mobile communication device interface element, and a second computer readable medium coupled to the second processor and comprising code executable by the second processor to implement a method comprising determining whether the second wireless apparatus is within a particular distance from the first wireless apparatus, and locking the mobile communication device from use if the second wireless apparatus is not within the particular distance from the first wireless apparatus. Some embodiments may lock the mobile communication device from use if a tamper switch has been triggered.

    • Systems and methods are presented for an improved power adapter. On one potential embodiment, an improved power adapter is described that is made up of an AC input; a rectifier coupled to the AC input; a power factor correction circuit coupled to the rectifier; and a burst switch circuit coupled to the power factor correction circuit. The burst switch circuit provides power to a DC output via a set of FET drivers, a set of FETs, and a transformer, and wherein the burst switch circuit provides power exclusively in a burst mode using a feedback input from the DC output. The transformer may be composed of a first winding coupled to the set of FETs, and second, third, fourth, and fifth windings each coupled to the first winding, wherein the second winding and the third winding are embedded in a printed circuit board; and wherein the fourth and fifth winding each comprise a conductive ribbon that loops around a transformer core. In additional embodiments, multiple monitoring circuits are integrated with DC tip and USB outputs in a power adapter with a high power density.
    • 提出了一种改进的高功率密度电源适配器的系统和方法。 在一个潜在的实施例中,改进的电力适配器包括AC输入; 耦合到AC输入的整流器; 耦合到整流器的功率因数校正电路; 以及耦合到功率因数校正电路的脉冲串开关电路。 脉冲串开关电路通过一组FET驱动器,一组FET和变压器为DC输出提供电力,并且可以使用来自DC输出的反馈输入以突发模式提供功率。 变压器可以由耦合到该组FET的绕组和嵌入在PCB中并耦合到第一绕组的附加绕组组成。 某些绕组可包括环绕变压器芯的导电带。 另外的实施例可以包括监控电路和多个输出。
