Abstract: A method to indicate that a first device is in communication with a second device is disclosed. The first device may receive an indication activity from the second device. The indication activity may change the display and the illumination object on the first device and the displays on the illumination object and the display are similar.

Abstract: An input device may detect an input on an input device. The input may be compared to stored inputs to determine if the input is related to one of the stored inputs where the stored inputs can be user defined. If the input is related to one of the stored inputs, an action may be executed related to the stored input. If the input is not related to one of the stored inputs or is not recognized, the steps of the method may be repeated. The actions associated with different gestures may be defined by the user.

Abstract: One embodiment of the present invention provides a switching device that can vary a spin-polarized current based on an input signal. The switching device comprises a first conducting region, a second conducting region, and a half-metal region interposed between the first conducting region and the second conducting region. The half-metal region comprises a material which, at the intrinsic Fermi level, has substantially zero available electronic states in a minority spin channel. Changing the voltage of the half-metal region with respect to the first conducting region moves its Fermi level with respect to the electron energy bands of the first conducting region, which changes the number of available electronic states in the majority spin channel, and in doing so, changes the majority-spin polarized current passing through the switching device.
