  • Patent number: 8941594
    Abstract: An interface, apparatus, circuit and method for interfacing with an electronic device, such as a cellular telephone, are disclosed. The interface includes a key pad with a number of keys, each operable for providing a unique input to the electronic device, and a actuator for selectively actuating one or more of the keys. A controller, coupled to the key pad, scans the keys according to a mode of operation of the electronic device. A mode selector, operable with the controller, selects a first or second operating mode. In the first, useful for instance in performing telephonic functions, each key provides its unique input discretely. In the second mode, useful for instance for providing a game related function, certain of the keys are selectively chorded to function for providing their respective inputs together, effectively simultaneously, according to a manipulation of the actuator by the user.

  • Patent number: 8917243
    Abstract: Systems and methods for illuminating a keycap on a keyboard are described. One system comprises a first light source positioned below the keycap on the keyboard and arranged to illuminate a portion of a bottom of the keycap. The system also comprises a second light source, adjacent the first light source, positioned below the keycap and arranged to illuminate a portion of the bottom of the keycap. One method of illuminating a keycap on a keyboard comprises activating a first light source, wherein the first light source and a second light source are positioned below the keycap on the keyboard, and activating the second light source responsive to the first light source operating outside a predetermined threshold parameter.
