| 20110173193 | GEOTEMPORAL SEARCH - Computer-readable media and a computing device are described for providing geotemporal search and a search interface therefor. A search interface having a location portion and a timeline portion is provided. A geographic area is selected in the location portion by adjusting the visible area of a map. A temporal window is selected in the timeline portion by adjusting sliders along a timeline to a desired start and end time. The start and end times can be in the past, present, or future. A geotemporal search is executed based on the selected geographic area and temporal window to identify search results having associated metadata indicating a relationship to the selected geographic area and temporal window. One or more search terms are optionally provided to further refine the geotemporal search. | 07-14-2011 |

| 20120034465 | METHOD FOR PREPARING SILICA-DYSPROSIUM OXIDE CORE-SHELL NANOPARTICLES - Silica-dysprosium oxide core-shell nanoparticles and a method for preparing the silica-dysprosium oxide core-shell nanoparticles are disclosed. Initially, ethyl silicate, n-butanol, ethylenediamine, and distilled water are mixed in the presence of ultrasonic radiation to prepare silica nanoparticles. Then, the silica nanoparticles are isolated. Next, the isolated silica nanoparticles, an acid, n-butanol, and dysprosium oxide are mixed in the presence of ultrasonic radiation to prepare silica-dysprosium oxide core-shell nanoparticles. Finally, the silica-dysprosium oxide core-shell nanoparticles are isolated. | 02-09-2012 |

| 20100108776 | ADJUSTABLE COLD SPRAY NOZZLE - A cold spray nozzle assembly includes a venturi having converging and diverging portions interconnected at a throat. An air supply conduit is in communication with the venturi for supplying a carrier gas to the converging portion. A powder feed tube is in communication with the venturi for supplying a powder material. An adjustment member is arranged within the venturi and is axially moveable relative thereto between multiple positions. The multiple positions respectively provide multiple different areas or throat clearances including a desired area between the adjustment member and the venturi or throat clearance. As a result, the adjustment member can be axially positioned to achieve desired gas pressures, deposition rates, and accommodate machining tolerances and component wear based upon the selected area. A retention member maintains the adjustment member in the desired position during operation of the cold spray nozzle assembly. | 05-06-2010 |

| 20100003639 | POROUS IMPLANT WITH NON-POROUS THREADS - An implant which includes a shaft made of a first material and having an exterior surface, and at least one thread made of a second material different from the first material, engaging the exterior surface, and extending outwardly from the exterior surface for engaging bone. After implantation of the implant, bone tissue may osseointegrate into the porous shaft to anchor the implant within the surrounding bone. The first material may be a porous metal and include tantalum while the second material is non-porous. | 01-07-2010 |
| 20100003640 | IMPLANT WITH STRUCTURE FOR SECURING A POROUS PORTION - An implant includes a head portion, an intermediate portion and an initially separate stem portion configured to engage the head portion so that at least the head portion and the stem portion cooperatively secure the intermediate portion on the implant. The implant may also include a locking mechanism configured to secure the head portion to the stem portion by a press fit or a threaded connection. The intermediate portion may include a porous metal such as tantalum. | 01-07-2010 |

| 20110164231 | OPTICAL NANOLITHOGRAPHY SYSTEM AND METHOD USING A TILTING TRANSPARENT MEDIUM - An optical nanolithography system and a method for optical nanolithography using a tilting transparent medium are disclosed. Initially, a pattern is exposed on a substrate at a first location by sending electromagnetic energy through the tilting transparent medium at a first angle. Then, the angle of the tilting transparent medium is changed to a second angle that is different from the first angle. Next, the pattern is exposed on the substrate at a second location by sending electromagnetic energy through the tilting transparent medium at the second angle. The second location is different from and partially overlaps with the first location. Then, the substrate is developed so that overlapping regions of the substrate exposed by the pattern at the first location and at the second location are developed differently from non-overlapping regions of the substrate exposed by the pattern only at the first location or at the second location. | 07-07-2011 |
