Abstract: A method and apparatus for controlling a plurality of light sources (102,103,104,105) in an electronic device (100) is provided. In one embodiment, the plurality of light sources (102,103,104,105) is used to backlight an illuminated display (101). As switching multiple light sources on simultaneously can cause output voltages of power sources (219) to drop, thereby potentially affecting the overall operation of the electronic device (100), an illumination controller (107) distributes actuation times associated with illumination control signals (204,205,206,207) such that each actuation time is unique. A control signal generator (201) produces a control signal (202) having light source actuation information stored therein. The illumination controller (107) then generates a plurality of illumination control signals (204,205,206,207) that are capable of actuating the plurality of light sources (102,103,104,105).

Abstract: A wireless communication device (10) includes a radio frequency transceiver (22) adapted for burst transmission responsive to an enable signal in accordance with at least one communication protocol and an infrared transceiver (24) adapted for asynchronous data communication. The infrared transceiver (24) is responsive to the enable signal to suspend data communication. A controller (20) is coupled to each of the radio frequency transceiver (22) and the infrared transceiver (24), and the controller (20) is operable to generate the enable signal in accordance with the at least one communication protocol.
