| 20100047740 | DENTAL CROWN REMOVER - A dental crown remover has forceps with opposing beaks. Each of the beaks has a flattened base and a notch located at the base. The faces of the notch form an angle of about 90 degrees to one another, and the lower face of the notch intersects the base at about a 50-degree angle. The notch is intersected by a longitudinal cavity having a width less than that of the beak. This structure defines two sharp points where the longitudinal cavity intersects the base of the beak and the lower face, and two stops where the longitudinal cavity intersects the upper face of the notch. When the beaks of the forceps are moved toward closure, the points of each beak are capable of penetrating and holding a crown, providing stable support at least at four points, which support allows twisting and rocking motion to be applied to break the tooth-to-cement bond holding the crown in place. | 02-25-2010 |

| 20100328677 | Estimating spectral distribution of reflections from object surface based on low frequency illumination - A system for estimating the specular roughness of points on a surface of an object may include a lighting system, an image capture system and a computer processing system. The lighting system may be configured to illuminate the surface of the object at different times with different illumination patterns. Each illumination pattern may illuminate the surface from a plurality of different directions and form an intensity gradient having an order of no more than two. The image capture system may be configured to capture an image of the surface of the object when illuminated by each of the different illumination patterns at each of the different times. The computer processing system may be configured to compute the specular roughness of each point on the surface of the object based on the images captured by the image capture system. | 12-30-2010 |

| 20120056994 | SINGLE-SHOT PHOTOMETRIC STEREO BY SPECTRAL MULTIPLEXING - Single-shot photometric stereo techniques are disclosed in which chromaticity is assumed to be a variable. Scene illumination includes three or more spectrally distinct light sources. A scene image is taken with a camera system configured to measure five or more different bands, or channels, of the visible light spectrum. The light sources can include narrow-band colored LED lights, possibly combined with color filters to refine the spectral distributions. In each configuration, a beam splitter assembly is used to align two or more color cameras having different color filters placed over their lenses. By use of such techniques, a single multispectral photograph of a subject provides enough information to recover both the full-color reflectance and the surface normals on a per-pixel basis. | 03-08-2012 |

| 20100278009 | Storage and Management System for Seismic Data Acquisition Units - A configuration for the deck of a marine vessel, wherein parallel and perpendicular travel paths, for movement of individual OBS unit storage baskets, are formed along a deck utilizing, in part, the storage baskets themselves. A portion of the deck is divided into a grid defined by a series of low-to-the-deck perpendicular and parallel rails and each square in the grid is configured to hold an OBS unit storage basket. Around the perimeter of the grid is an external containment wall which has a greater height than the rails. Storage baskets seated within the grid are configured to selectively form internal containment walls. Opposing internal and external containment walls define travel paths along which a storage basket can be moved utilizing a low, overhead gantry. A basket need only be lifted a minimal height above the deck in order to be moved along a path. The containment walls and the deck itself constraining uncontrolled swinging of baskets, even in onerous weather or sea conditions. The system is flexible to meet the needs of a desired operation since the internal walls of the grid can be reconfigured as desired in order to free up a particular storage basket or define a particular travel path. | 11-04-2010 |
| 20110286800 | DEPLOYMENT METHOD FOR OCEAN BOTTOM SEISMOMETERS - A method and apparatus for deployment and retrieval of ocean bottom seismic receivers. In one embodiment, the apparatus comprises a carrier containing a plurality of receivers attached to a remotely operated vehicle (ROV). The carrier comprises a frame in which is mounted a structure for seating and releasing said receivers. The structure may comprise a movable carousel or a movable conveyor or fixed parallel rails or a barrel. In the case of the barrel, the receivers are axially stacked therein. The structure is disposed to deliver said receivers to a discharge port on said frame, where the receivers are removable from said carrier. The apparatus includes a discharge mechanism for removing said receivers from said carrier. In another embodiment, the method comprises the steps of loading a carrier with a plurality of receivers, attaching said carrier to an ROV, utilizing said ROV to transport the carrier from a surface vessel to a position adjacent the seabed and thereafter utilizing said ROV to remove receivers from said carrier and place the receivers on the seabed. In yet another embodiment, an ROV adjacent the seabed engages a deployment line extending from the vessel. The deployment line is used to guide receivers attached thereto down to the ROV for “on-time” delivery and placement on the seabed. | 11-24-2011 |
