摘要： A method for controlling characteristics of an electronic device based on ambient light levels is provided. In one embodiment, the method includes receiving light at an ambient light sensor of a device and measuring components, such as color components, of the visible light. The component levels may be weighted differently by factors that vary based on the intensity of the light received by the ambient light sensor. Also, the brightness level of a light source in the device or color output of the device may be controlled based on the weighted component levels. Additional methods, systems, and devices relating to control of an electronic device based on sensed ambient light are also disclosed.

摘要： One embodiment of the present invention provides a system that uses a sound sensor to adjust the audio output of a device. During operation, the system uses the sound sensor to determine an ambient sound level for the environment in the proximity of the device. The system then adjusts a volume setting for the device adaptively based on the determined ambient sound level. Adaptively adjusting the volume setting allows the device to adapt to its audio environment and ameliorates potentially-disruptive audio outputs.

摘要： A computer keyboard includes a plurality of keys arranged in a pattern contained within a plane, a webbed structure defining openings for each of the keys, an illumination source, and one or more light pipes positioned along the webbed structure and arranged to deliver light from the illumination source to the keys, wherein each of the keys is illuminated thereby. Although the keys have the appearance of being backlit similar to traditional illuminated keyboards, the illumination source is actually located along at least one side of and within the same plane as the pattern of keys, rather than beneath the keys. The keyboard can thus be made thinner in such arrangements where the illumination source does not need to be located beneath the keys.
摘要翻译：计算机键盘包括以包含在平面内的图案布置的多个键，限定用于每个键的开口的网状结构，照明源，以及沿着网状结构定位的一个或多个光管，并布置成将来自照明源到键，其中每个键被照亮。虽然键具有类似于传统照明键盘的背光的外观，但是照明源实际上沿着键的图案而不是在键的下方沿着与键的图案相同的平面内的至少一侧并且位于同一平面内。因此，可以在这样的布置中使键盘更薄，其中照明源不需要位于键下方。

摘要： A method for reading a meter includes (1) capturing a first image of digits displayed by the meter, (2) roughly locating the digits by correlating the entire first image against symbols, (3) precisely locating the digits by correlating the digits against the symbols, which are now rotated, resized, and repositioned to maximize correlation, (4) determining and storing nominal centers of the digits in a nonvolatile memory. The method further includes (5) capturing a second image of the digits, (6) locating regions of interest in the second image according to the nominal centers, (7) determining vertical positions of full digits (or partial digits) in the regions of interest, (8) aligning symbols (or partial symbols) and the full digits (or the partial digits) according to the vertical position, and (9) correlating the symbol and the full digits (or the partial symbols and the partial digits).

摘要： The present invention can provide solutions to many common imaging problems, such as, for example, unevenly distributed illumination, shadows, white balance adjustment, colored ambient light and high dynamic range imaging. Imaging systems and methods can be provided through a computer (e.g., laptop or desktop) such that the system or method can take advantage of the computer's processing power to provide functionality that goes beyond typical camera. Such an imaging system may include an imaging device, a camera, a light source and a user interface.

摘要： Techniques and apparatus to provide improved visibility to user input devices, such as keys, are disclosed. In low light conditions, key legends can be difficult to distinguish. For example, often keys have legends on them to visually distinguish them from one another, but in low light conditions it can be difficult for users to visually identify the different keys. The legends can be textual and/or graphic. Hence, according to one embodiment, light from a nearby (e.g., attached) display device can be used to provide illumination to the user input devices (e.g., keys). The user input devices can be configured to include reflective optical components to enhance reflection of light and thereby improve visibility of the keys or the legends thereon.
