Patent number: 9255345Abstract: A bulk manufacturing method for growing silicon-germanium stained-layer superlattice (SLS) using an ultra-high vacuum-chemical vapor deposition (UHV-CVD) system and a detector using it is disclosed. The growth method overcomes the stress caused by silicon and germanium lattice mismatch, and leads to uniform, defect-free layer-by-layer growth. Flushing hydrogen between the layer growths creates abrupt junctions between superlattice structure (SLS) layers. Steps include flowing a mixture of phosphine and germane gases over a germanium seed layer. This in-situ doped germanium growth step produces an n-doped germanium layer. Some of the phosphorus diffuses into the underlying germanium and reduces the stress in the underlying germanium that is initially created by the lattice mismatch between germanium and silicon. Phosphine can be replaced by diborane if a p-doped layer is desired. The reduction of stress results in a smooth bulk germanium growth.Type: GrantFiled: July 16, 2014Date of Patent: February 9, 2016Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Vu Anh Vu, Sandra L.

Publication number: 20140290707Abstract: A customization kit for a hand-held umbrella and methods fostering customization of such an umbrella are provided. In one disclosed embodiment, the method allows arranging in a baseline umbrella configuration one or more removable components for the umbrella. The removable component may be a component which is unblocked relative to a view of an external observer when the umbrella is in a closed condition. The method further allows configuring a customizing kit including an assortment of customizing components at least some of which are in a pre-finished condition, removing the removable component, and performing a customizing action in connection with the removable component resulting in a transformed umbrella look perceivable by the external observer when the umbrella is in the closed condition. In another embodiment, the customizing action may be accomplished with a replacement component manufactured by way of additive manufacturing.Type: ApplicationFiled: March 25, 2014Publication date: October 2, 2014Applicant: STINGR Solutions LLCInventor: Daniel J.

Patent number: 5726657Abstract: A radar system in which a frequency agile synthesizer is used to provide rapid frequency shifts and in which measures are taken to maintain phase coherency. The system is fully coherent such that all signals are derived from a common source and are capable of high pulse repetition rates in excess of 1 MHz. There are no inherent transmit duty cycle restrictions and the system is able to transmit complex phase and frequency modulated waveforms. A frequency interleaving scheme is used to resolve range ambiguities at high pulse repetition frequencies and the use of a complementary phase coding scheme allows a high range resolution processing with the transmitted waveforms.Type: GrantFiled: March 22, 1996Date of Patent: March 10, 1998Assignee: Lockheed Martin CorporationInventors: Albert N.
