20110146771 | NANONEEDLE PLASMONIC PHOTODETECTORS AND SOLAR CELLS - The present disclosure provides a catalyst-free growth mode of defect-free Gallium Arsenide (GaAs)-based nanoneedles on silicon (Si) substrates with a complementary metal-oxide-semiconductor (CMOS)-compatible growth temperature of around 400° C. Each nanoneedle has a sharp 2 to 5 nanometer (nm) tip, a 600 nm wide base and a 4 micrometer (μm) length. Thus, the disclosed nanoneedles are substantially hexagonal needle-like crystal structures that assume a 6° to 9° tapered shape. The 600 nm wide base allows the typical micro-fabrication processes, such as optical lithography, to be applied. Therefore, nanoneedles are an ideal platform for the integration of optoelectronic devices on Si substrates. A nanoneedle avalanche photodiode (APD) grown on silicon is presented in this disclosure as a device application example. The APD attains a high current gain of 265 with only 8V bias. | 06-23-2011 |

After wafer bonding, the silicon is removed, gold-free electrodes (e.g., Al) are added, and the structure is singulated. High temperature solder (e.g., ZnAl) that is compatible with the electrode metal is used for die attach. Die attach occurs at >380° C. for ten seconds without melting the bond metal or otherwise damaging the device. The entire LED contains no gold, and consequently is manufacturable in a high-volume gold-free semiconductor fabrication facility. | 02-07-2013 |

20110010005 | SYSTEM FOR ASSOCIATING INVENTORY WITH HANDLING EQUIPMENT IN SHIPPING CONTAINER YARD INVENTORY TRANSACTIONS - A system is provided to associate containers with handling equipment (HE) in a container storage facility. In the system an operation detector, such as a twistlock sensor that indicates when a container is picked up or dropped off, is installed on a first HE which is a piece of container handling equipment (CHE) that can lift the container. An event detector, such as a vibration sensor or distance measuring radar, is further installed on a second HE that is a tractor with an attached chassis for receiving and transporting a container. The event detector indicates when a container-operation-related event, such as a container pick up or drop off, occurred on the tractor chassis. The two detectors (operation and event) are used by a processor to associate the container with either the CHE or the tractor. The operation and event detectors can further be used in conjunction with position sensors such as a GPS sensor to accurately determine the position of the tractor and the CHE in a container yard. When the position sensors degrade in performance, an additional motion detector such as a speed sensor can be used to determine the tractor's distance from the CHE to locate an appropriate tractor involved in the operation. | 01-13-2011 |

In each of the checking steps, the processor selects an error type from the list of error types, determines a search criterion based on the selected error type and the first data record, queries the database using the search criterion, compares query results with the first data record to detect data conflicts between them, and upon the detection of the data conflicts, reports that a data error of the selected error type has been detected. | 03-03-2011 |

Specifically, electrons populating defect energy levels of a band gap in an optical material can be promoted to the conduction band—a process commonly referred to as bleaching. Such bleaching can be accomplished using a predetermined wavelength that ensures minimum energy deposition into the material, ideally promoting electron to just inside the conduction band. In some cases phonon (i.e. thermal) excitation can also be used to achieve higher depopulation rates. In one embodiment, a bleaching light beam having a wavelength longer than that of the laser beam can be combined with the laser beam to depopulate the defect energy levels in the band gap. The bleaching light beam can be propagated in the same direction or intersect the laser beam. | 07-17-2014 |
