    摘要： A light emitter/sensor includes a lamp, a light sensor, a light guide, and a light controller. The light guide has a pair of opposite ends and is optically-coupled to the lamp and the light sensor at one of the ends. The light guide is configured to convey light emitted from the lamp to the other end of the light guide, and from that other end to the light sensor. The light controller is coupled to the lamp and the light sensor and is configured to flash the lamp and to determine the intensity of light at that other end of the light guide, via the light guide and the light sensor, during an interval between the flashes.

    摘要： A portable computing device includes a housing having an external surface, and an event notifier, a display device, and a light controller disposed within the housing. The event notifier includes an event notification lamp, and a light conduit terminating at the external surface for conveying light between the event notification lamp and the external surface. The display device includes illumination means for improved visualization of information rendered on the display device. The light controller is coupled to the event notifier and the illumination means. The light controller is configured to determine the intensity of ambient light external to the housing via the light conduit, and to adjust the intensity of light emitted by the illumination means in accordance with the determined ambient light intensity.

    摘要： In a handheld computing device that includes a backlit display having a variable-intensity backlight, a method for controlling the intensity of light produced by the backlight involves the following steps. The computing device also includes user data input means, and data processing means coupled to the user data input means and the backlit display. The data processing means includes at least one software application that is configured to display information on the display. The method involves the steps of (1) setting the intensity to a first intensity level and activating one of the software applications; and (2) setting the intensity to a minimum intensity level, less than the first intensity level, after expiry of a predetermined elapsed time of non-activity from the user data input means. The predetermined elapsed time is based on the activated software application.
