Abstract: A wireless power infrastructure for delivering wireless power from a wireless network to mobile devices. The infrastructure includes a plurality of power transmission hubs, each hub having: a first capacitor for transmitting a signature frequency for a defined range; and a set of second capacitors, each for transmitting resonant wireless power within the defined range at a selectable frequency. A mobile device for obtaining wireless resonant the plurality of power transmission hubs is also described, and includes: a first variable capacitor for detecting a signature frequency associated with a proximately located power transmission hub; a second variable capacitor for receiving wireless resonant capacitor from the proximately located power transmission hub; and a synchronization system for setting the second variable capacitor to a frequency that is synchronized with a wireless resonant power transmission of the proximately located power transmission hub.

Abstract: A keyboard that includes at least two planes of keys and a communication port. The keyboard can be configured to include a back-to-back position. In the back-to-back position, the planes can be jointed so that each plane has outwardly facing keys which are fixed relative to the other plane at approximately a one-hundred and eighty degree angle (e.g., between one hundred and seventy degrees and one hundred and eighty degrees) relative to the other plane. The communication port can establish a communication linkage between the keyboard and a computing device. When in the back-to-back position, key presses from the keyboard are able to be conveyed across the communication linkage to be interpreted as input by the communicatively linked computing device.
