This relates to a method for controlling illumination of a display screen on a mobile device. A light source is turned on to illuminate the display screen. An amount of information displayed on the display screen is identified. An amount of time to keep the light source turned on is determined based at least in part on the identified amount of information. The light source is kept turned on at a first intensity level for the amount of time and then turned to a second intensity level.

LCD backlight duration proportional to amount of information on the LCD display screen

A method is set forth for automatically adjusting screen and keypad brightness on a mobile electronic device having a light sensor, display screen and keypad, for optimum legibility under varying lighting conditions, with minimal eye strain and distraction. The method includes obtaining light level samples from the light sensor, and independently adjusting backlight intensity of the display screen and keypad responsive to the light level samples. Preferably, correct screen and keypad adjustments are made responsive to pulling the handheld device out of its holster notwithstanding non-optimal ambient light detection while the device is being removed from the holster. According to another aspect, the described method allows for ambient light detection in a handheld device where the light sensor and a message notification indicator share a common light pipe.

Automatic screen and keypad brightness adjustment on a mobile handheld electronic device

The invention provides a hovering aerial vehicle with removable rotor arms and protective shrouds. Removing the shrouds reduces the weight of the vehicle and increases flight time. Removing the rotor arms makes the vehicle easier to transport. Removable rotor arms also simplify field repair or replacement of damaged parts.

According to another aspect, the described method allows for ambient light detection in a handheld device where the light sensor and a message notification indicator share a common light pipe.

A method, and device incorporating the method, permits adjustment of the on time of a light source that illuminates a display within a handheld wireless communications device. The on time may be adjusted by the amount of information to be displayed, the font size of the information, the behavioral characteristics of the end user, the type of viewing activity, and the like. An optional dim mode permits the end user to be made aware that the light illuminating the display is about to be shut off.
