Title: Enhanced visualization of in-vivo breast biopsy location for medical documentation
Inventor: CARROTT DAVID T
IPC: A61B8/00
Filed: 2001-03-20
Granted: 2005-05-31
Abstract: An image processing system and method visually documents and displays the in-vivo location from which a biopsy specimen was extracted, by processing pre-biopsy and post-biopsy images. A  composite image is created which visually emphasizes differences between the pre-biopsy and post-biopsy images. Preferably three-dimensional, digitized images, displayable in various projections, are stored for archival purposes on computer readable media. An image processor (24) preferably exploits an optical correlator (30) to register the pre-biopsy and post-biopsy images accurately.  The images are then compared, voxel-by-voxel, to detect differences between pre-biopsy and post-biopsy images. The composite image is displayed with synthetic colors, synthetic icons, or other visual clues to emphasize probable in-vivo biopsy locations.

IPC: F21V29/15
Filed: 2003-09-26
Granted: 2011-03-22
Abstract: A self-ballasted fluorescent lamp that comprises a housing formed to contain a ballast. The housing has a top surface with openings leading from the exterior of the housing to the interior.  The openings can be in the form of raised bosses having upstanding walls. A  restricted portion, which can take the form of a flange, is formed with the opening and a safe end-of-life enabling device is positioned in the opening and in contact with the restricted portion. The safe end-of--life device is tubular, has low thermal conductivity and in preferred forms of the invention is a glass such as quartz or a ceramic such as aluminum oxide. The ends of a fluorescent lamp penetrate the tubular end-of-life device and extend into the interior of the housing for suitable connection to an enclosed electronic ballast. A retainer is positioned opposite the restricted portion for maintaining the end-of-life device within the opening. The retainer is a typical compact fluorescent cement that is used to fix the lamp to the housing.  Alternatively, the retainer can be an adhesive silicone or a threaded washer.

Title: Atmospheric and vacuum pressure maldi ion source
Inventor: WHITEHOUSE CRAIG M
IPC: H01J49/42
Filed: 2002-05-24
Granted: 2010-01-26
Abstract: A Matrix Assisted Laser Desorption Ionization (MALDI) Source (1) operated at atmospheric or vacuum pressure is interfaced to a multipole ion guide (8) or ion funnel with alternating current "AC or RF" waveforms applied. The multipole ion guides (8, 68) or ions funnels are configured to focus transport, trap and/or separate ions produced from a MALDI ion source (1) and direct the MALDI produced ions to a mass analyzer (3) for MS or MS/MSn mass to charge analysis. The MALDI sample targets (4) can be positioned at the entrance of a multipole ion guide (8) or ion funnel with gas flow (14) and electric fields configured to direct ions efficiently into the ion guide (8) or ion funnel. Ions produced by MALDI (1) operated at atmospheric or intermediate vacuum pressures experience ion to neutral gas collisions as they are transported in the multipole ion guide (8) or ion funnel in the presence of RF electric fields. The gas collisions serve to damp the ion trajectories toward the ion centerline, improving ion transport efficiency into and through vacuum. Ion mobility and mass to charge separation of ions can be performed in the multipole ion guide and ion funnel devices while transporting and focusing ions.

Abstract: L'invention concerne un appareil d'altération d'images permettant une vision confidentielle sur un affichage vidéo par des moyens de multiplexage temporel d'une image fondamentale avec une image à couleurs inverses sur une base de pixel par pixel. Des circuits électroniques et/ou un logiciel sont utilisés pour modifier le signal de l'image fondamentale par multiplexage temporel de ses composants de données de couleurs avec les composants de données de couleurs inverses afin de générer un signal d'image composé qui est représentatif d'une image sensiblement monotone. Des séquences différentes de multiplexage de composants de données de couleurs et de composants de données de couleurs inverses peuvent être utilisées sur des temps de mise sous tension variables pour générer une image composée très confidentielle et sécurisée contre des visualisations non autorisées. Ladite image fondamentale peut être décodée et visualisée uniquement par ceux qui visualisent l'image codée à travers des lunettes spécialement conçues qui contiennent des obturateurs ACL synchronisés, des polariseurs variables, ou des filtre de couleur, qui peuvent bloquer de manière sélective des composants de couleurs inverses et/ou démoduler l'image fondamentale afin de laisser passer uniquement les véritables composants de couleurs fondamentaux, fournissant de ce fait à l'observateur une visualisation confidentielle et très sûre de l'image fondamentale.

Abstract: A seismic survey system having remote acquisition modules (RAMs) for acquiring seismic signals and communicating with a central recording system (CRU) via a network of cables, other RAMs, and line tap units (LTUs), arranged in a matrix of receiver lines and base lines. Each RAM cyclically converts analog signal values to digital, forming data packets. Interrogation commands emanating from the CRU and relayed with strategic delays by intervening LTUs and RAMs are received by the RAM. Each command causes the RAM to transmit a data packet.  Strategic delays are set such that the transmission capacity of the line is best utilized. Power and frequency of transmission are selectable by the CRU  to optimize performance. Cables contain multiple communication pairs. The network path between the RAM and the CRU is established from the CRU and altered in event of malfunction. All types of network elements are interconnectable. Recorded samples are synchronous.
