    摘要： This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for controlling brightness of a display based on ambient light conditions. In one aspect, a display device can include a reflective display and an auxiliary light source configured to provide supplemental light to the display. The display device further can include a sensor system configured to determine an illuminance of ambient light, and a controller configured to adjust the auxiliary light source to provide an amount of supplemental light to the display based at least in part on the determined illuminance. In one aspect, the amount of supplemental light remains substantially the same or substantially increases in response to increasing illuminance when the illuminance is below a first threshold, and substantially decreases in response to increasing illuminance when the illuminance is above a second threshold that is greater than or equal to the first threshold.

    摘要： A symbol synchronizer (10) for use in a communication device. The symbol synchronizer (10) comprises a sampling circuit (100) which samples the demodulated signal at a plurality of sampling events for each symbol period to generate three sample values at each sampling event. An eye pattern detector circuit (200) generates eye pattern characteristic information based on the three sample values, and outputs a symbol pulse in response to detecting eye pattern characteristic information consistent with a symbol center. A synchronization noise mask circuit (400) filters symbol pulses that occur during a predetermined period of time after a first symbol pulse is detected for each symbol period. A synchronization adjust circuit (500) generates a synchronization pulse during each symbol period at a particular instant of time during the symbol period based on a history of the occurrences of symbol pulses for a current symbol period and for prior symbol periods.

    摘要： Embodiments of a panel lighting apparatus and methods of its manufacture are described. In one embodiment, the apparatus can include a light source, an at least partially transparent panel comprising a planar front surface and a planar back surface, the panel disposed in conjunction with the light source such that light from the light source is input into at least one edge of the panel and guided therein, and a plurality of light extraction dots disposed on the planar back surface, the plurality of light extraction dots configured to reflect light incident on the planar back surface and extract light from the light source propagating in the panel through the planar front surface.
