Abstract:
A method of adjusting electromagnetic radiation transmitted by an optical element is described. The method includes sensing the electromagnetic radiation transmitted by the optical element to produce sensed electromagnetic radiation information, and adjusting the sensed electromagnetic radiation information to produce adjusted electromagnetic radiation information based on the a spectral transmission of the optical element.
Abstract:
A system and method for optically identifying a component coupled to an electronic device is provided. The method includes emitting light from within the device toward a surface of a component connector inserted into a receiving socket of the device. A light sensor senses the intensity, amplitude or wavelength of light reflected from a surface of the component connector. A processor of the device identifies the component based on the intensity, amplitude or wavelength of light reflected from a surface of the component connector. The processor modifies at least one setting of the electronic device in response to the identification of the component.
Abstract:
Electronic displays encounter visibility issues due to varying ambient light conditions. An ambient light sensor can be provided to sense ambient light and dynamically adjust display brightness to compensate for changes in ambient light. A wave guide for improving angular response in a light sensor is provided.
Abstract:
A device is provided that includes an ambient light level sensor, a proximity sensing system, and a processor. The ambient light level sensor generates a signal as a function of an ambient light level at the device. The proximity sensing system comprises an emitter component. The processor is configured to receive the signal from the ambient light level sensor and to adjust an electrical current through the emitter component based on the signal.

Abstract:
A light guide apparatus for an electronic device is described. The light guide apparatus includes a light guide having a first surface and an second surface; a light source, the light guide and the light source being arranged to couple light from the source into the light guide through the second surface of the light guide, the second surface and the light source defining a gap therebetween; and a reflector positioned above the light source and the light guide, and extending over at least a portion of the gap and at least a portion of the front surface of the light guide.
Abstract:
An input device includes an array of keys and an illumination system. Each key comprises a key face that is configured for transmission of light. The illumination system includes a light guide disposed below the keys, a plurality of lamps mounted to the light guide, and a lamp controller electrically coupled to the lamps. The light guide is configured to illuminate the key faces via the lamps. The lamp controller is configured to repeatedly illuminate the lamps each for a respective on-time interval of a common illumination period. The location of the lamps and the illumination period and each said on-time interval are selected for the visual appearance of continuous substantially uniform illumination of the array of keys.
Abstract:
A method and system are set forth for automatically adjusting keypad luminance based on display content. In one embodiment, the method comprises calculating a lighting level based on ambient light; calculating a luminance level of an image on the display; setting a maximum lighting level to the luminance level of the image on the display; and in the event the calculated lighting level exceeds the maximum lighting level then selecting the maximum lighting level, and in the event the calculated lighting level does not exceed the maximum lighting level then selecting the calculated lighting level.
Abstract:
A light guide guides light from a light emitter that is adjacent to an aperture of an electronic device. The light is eventually emitted from the aperture, to thereby provide lighting. The light guide can include a plurality of prisms which can thereby permit reduction in the overall thickness of the electronic device.
