20120169240 | SEMI RESONANT SWITCHING REGULATOR, POWER FACTOR CONTROL AND LED LIGHTING - Described are improvements in power factor control and systems embodying said improved power factor control. Improvements lie in a method of zero voltage switching in which a capacitor is placed in parallel with a switching device, and the switching device is operated responsive to a change in the polarity of the current through the capacitor. Switching therefore occurs at zero or close to zero voltage across the switching device in both on and off modes resulting in very low switching losses and electromagnetic interference. Systems employing the method include a power factor controller, LED light source, boost converter and a power source comprising one or more photovoltaic cells. | 07-05-2012 |

20150103200 | HETEROGENEOUS MIX OF SENSORS AND CALIBRATION THEREOF - Aspects of calibration of sensors are described. In one embodiment, a characteristic associated with a first or a second sensor is identified. The characteristic may be identified before or after assembly of a device including the first and second sensors. In turn, an operating characteristic of at least one of the first sensor or the second sensor may be adjusted based on the identified characteristic. Further, a first image may be captured with the first sensor and a second image may be captured with the second sensor. An attribute of the second image, for example, may be adjusted to substantially address any difference between the attribute of the second image and a corresponding attribute of the first image using the characteristic for calibration. The adjustments described herein may assist various processing techniques which operate on pairs of images, for example, particularly when a heterogeneous mix of sensors is used. | 04-16-2015 |
20150104074 | DEPTH MAP GENERATION AND POST-CAPTURE FOCUSING - Aspects of depth map generation and post capture focusing and re-focusing are described. According to one embodiment, a depth map is generated. The depth map may include a mapping among relative depth values in a field of view of an image based on a difference between pixels of a first image and pixels of a second image. An edge map may also be generated by identifying edges in at least one of the first image or the second image. Using the depth map and the edge map, the relative depth values in the depth map may be smoothed using the edge map. In this manner, certain discontinuities in depth values may be smoothed within edge-bounded regions defined by the edge map. The depth map may be used for focusing and re-focusing, for example, or for object extraction, scene understanding, or gesture recognition, among other imaging processes. | 04-16-2015 |

20130314062 | DC-DC CONVERTERS OPERABLE IN A DISCONTINUOUS SWITCHING MODE - Methods and apparatus for control of DC-DC converters, especially in valley current mode. The DC-DC converter is operable so that a low side supply switch may be turned off, before the high side supply switch is turned on. During the period when both switches are off the current loop control remains active and the change in inductor (L) current is emulated. One embodiment uses a current sensor for lossless current sensing and emulates the change in inductor current by holding the value of the output of the current sensor (ISNS) at the time that the low side switch turns off and adding an emulated ramp signal (VISLP) until the inductor current reaches zero. Embodiment employing a pulse-skip mode of operation based on a minimum conduction time are also disclosed. The invention enables a seamless transition from Continuous Conduction Mode the Discontinuous Conduction Mode and Pulse Skipping and provide converters that are efficient at low current loads. | 11-28-2013 |
