    • 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.
