20110169421 | METHOD AND APPARATUS FOR PROVIDING ILLUMINATION WITH A PULSE-CONTROLLED LIGHT EMITTING DIODE SOURCE - An array of LEDs includes first and second rows of LEDs. The LEDs emit light at red, green, and blue wavelengths parallel to an output port, and the light is re-directed by a light reflecting material from directions parallel to the output port toward the output port. The first and second rows are parallel to each other, and the LEDs are powered by pulse width modulated signals that establish a brightness of the LEDs. | 07-14-2011 |

20140362364 | TIME-OF-FLIGHT RANGING SYSTEM AND METHOD WITH EXTENDED RANGE - An embodiment includes a method, comprising: receiving a modulated signal having modulation; generating a first signal in response to the modulation and a first sampling signal; generating a second signal in response to the modulation and a second sampling signal; and generating a distance in response to the first signal and the second signal. A ratio of a frequency of the first sampling signal to a frequency of the second sampling signal is a rational number. | 12-11-2014 |

20090140660 | PULSE-CONTROLLED LIGHT EMITTING DIODE SOURCE - A light-emitting diode array is driven by a digital control. The digital control modulates the pulse width of pulses applied to the light-emitting diode. The intensity of the output is controlled by controlling the width of pulses applied to the light-emitting diode. Since light-emitting diodes have very low inertial energy, this system can be rapidly turned on and turned off. The output is integrated to produce a uniform output. | 06-04-2009 |
