Abstract: Connectors and methods of coupling electronic devices and cables are provided. In one embodiment, a connector has a first coded magnet on a first surface of a first device. The first coded magnet has at least two different polarity regions on the first surface. A second coded magnet on a second surface of a second device is also provided. The second coded magnet is configured to provide identifying information regarding the device on which it is located.

Abstract: Security devices and methods of securely coupling electronic devices and peripherals are provided. In one embodiment, a peripheral has a first coded magnet on a first surface of a first device. The first coded magnet has at least two different polarity regions on the first surface. A second coded magnet on a second surface of a second device is also provided. The first coded magnet is configured to securely provide data to a device associated with the second coded magnet, if the first and second coded magnets' patterns are keyed to one another.

Abstract: The disclosed embodiments relate to the design of a portable and cost-effective fuel cell system for a portable computing device. This fuel cell system includes a fuel cell stack which converts fuel into electrical power. It also includes a fuel source for the fuel cell stack and a controller which controls operation of the fuel cell system. The fuel system also includes an interface to the portable computing device, wherein the interface comprises a power link that provides power to the portable computing device, and a bidirectional communication link that provides bidirectional communication between the portable computing device and the controller for the fuel cell system.

Abstract: Methods and apparatuses are disclosed to correct for tilt and/or perspective distortion in image capture devices. In some embodiments, the method may include reading an orientation measurement associated with a relative position of an image capture device with respect to an object, determining if the orientation measurement is less than a threshold, and in the event that the orientation measurement is less than the threshold, correcting an image obtained by the image capture device. In some embodiments, the apparatus may include an image sensor, a memory coupled to the image sensor, an orientation measurement device coupled to the image sensor, and a distance measurement device coupled to the image sensor, where the image data may be stored in the memory along with a measurement from the accelerometer and along with a measurement from the distance measurement device.
