摘要： In a handheld computing device that includes a backlit display having a variable-intensity backlight, and a function key, a method for controlling an intensity of light produced by the backlight involves the steps of (1) setting the intensity to a first level sufficient for viewing information on the display under first ambient lighting; and (2) upon activation of the function key, setting the intensity to a second level sufficient for viewing information on the backlit display under second ambient lighting that is different than the first ambient lighting.

摘要： A method and system for automatically adjusting a backlight intensity level for displays is disclosed. The system and method are implemented in electronic devices having a camera and digital backlit displays, such that the camera is used to determine an ambient light level and the backlight level is adjusted according to the determined ambient light level. In particular, when the camera is not in use for capturing images by the user, the automatic backlight adjustment system captures a first image with the camera to determine an initial ambient light level, and then captures a second image with the camera at a later time to determine a subsequent ambient light level. The subsequent and initial ambient light levels are compared to each other and the backlight intensity level is either increased or decreased a predetermined amount for optimal viewing and low power consumption. Backlight intensity determination can be performed on the basis of a single image instead of a differential between two images.

摘要： An improved power supply system involves load-leveling the large transient currents drawn by a high power, low duty-cycle load application circuit by means of a high performance capacitive charge storage device, such as a super-capacitor or a network of super-capacitors. The improved power supply system allows the high power load application circuit to be driven by a limited energy power source, such as a battery or the power supplied to a PCMCIA slot by a host computer. When the input voltage source is a battery, the improved power supply system allows for a substantial increase in the battery's operational life. The inventive system is particularly useful for managing power supply requirements for miniaturized wireless transmission systems, such as two-way pagers or radio modems, which employ low duty-cycle packet-switched RF transmitters.
