The controller may also include a manual mode in which upon detecting a call-waiting signal from an incoming communication, the controller actuates one or more alarms indicating an incoming communication.

Abstract: An apparatus for illuminating a portable electronic or computing device includes a plug for plugging the apparatus into a port of the device, a body connected to the plug, and an illumination device attached to the body and to be electrically connected to the port through the plug and the body. The illumination device includes one or more light emitting diodes to illuminate the portable electronic device. The one or more light emitting diodes require a required power to be effectively illuminated. The illumination device is powered by a power source of the portable electronic or computing device when the apparatus is plugged into the port. A circuit delivers the required power to the one or more light emitting diodes regardless of the power delivered at the port.

Abstract: A circuit efficiently drives light emitting diodes (LEDs). The circuit uses a switching regulator device instead of a standard resistor to limit current to the LEDs. The switching regulator device is in a closed loop with a current sensing device near the LED lamps. Feedback from this current sensing device switches the control method according to the current load regulating the voltage applied to the LEDs. An inductive storage device in the circuit allows the LEDs to be driven with minimal voltage input. Methods for intensifying and focusing the light produced by the LEDs driven by the circuit are also described.
