Method and system for robust and extended illumination waveforms for depth sensing in 3D imaging
The methods and systems disclosed herein improve upon previous 3D imaging techniques by making use of a longer illumination pulse to obtain the same or nearly the same range resolution as can be achieved by using a much shorter, conventional laser pulse. For example, a longer illumination pulse can be produced by one or more Q-switched lasers that produce, for example, 5, 10, 20 ns or longer pulses. In some instances, the laser pulse can be longer than the modulation waveform of a MIS-type imaging system and still produce a repeatable response function. The light pulse generation technologies required to achieve longer pulse lengths can be significantly less expensive and less complex than known technologies presently used to generate shorter illumination pulse lengths. Lower-cost, lower-complexity light pulse sources may facilitate lower-cost, commercial 3D camera products. |

The communication system supports a primary link and an alternate link, and the method and system leverage the alternate link to reduce the overhead transmitted over the primary link, thereby increasing throughput and reducing end-to-end latency. The higher latency alternate link provides a delayed version of an information signal that corresponds to a portion of the information signal that is transmitted on the primary link. The received samples from the primary and alternate links may be used to equalize subsequent portions of the information signal received over the primary link, and may also be used for synchronization, timing recovery, DC offset removal, I/Q imbalance compensation, and frequency-offset estimation. |

Method of attaching a lens to an LED module with high alignment accuracy
A light emitting device includes a light emitting element on a substrate, and a lens element that includes a cavity within which the light emitting element is situated, and is optically aligned with the light emitting element. A strip of adhesive that attaches the lens element to the substrate substantially surrounds the light emitting element, but includes a gap that facilitates release of material from the cavity during the attachment of the lens element to the substrate. When the lens element is placed upon the substrate, the adhesive is partially cured to provide a relatively high shear strength before the light emitting device is transported or subjected to other processes. To provide compatibility with subsequent processes or applications, and to protect the light emitting element from the environment, the gap in each device is sealed with a sealing material. |

A semiconductor arrangement and method of formation are provided herein. A semiconductor arrangement includes an active area on a substrate, where the active area is at least one of a p-type region or an n-type region. The substrate includes a well, where the well is a p-well when the active area is a p-type region, and the well is an n-well when the active area is an n-type region. The well includes a photodiode.

Thin refractory metal layer used as contact barrier to improve the performance of thin-film solar cells
A thin film amorphous silicon solar cell may have front contact between a hydrogenated amorphous silicon layer and a transparent conductive oxide layer. The cell may include a layer of a refractory metal, chosen among the group composed of molybdenum, tungsten, tantalum and titanium, of thickness adapted to ensure a light transmittance of at least 80%, interposed therebetween, before growing by PECVD a hydrogenated amorphous silicon p-i-n light absorption layer over it. A refractory metal layer of just about 1 nm thickness may effectively shield the oxide from the reactive plasma, thereby preventing a diffused defect when forming the p.i.n. layer that would favor recombination of light-generated charge carriers. |
