Patent number: 7227982Abstract: Methods for three-dimensional projecting and backprojecting rays with respect to voxels/detector bins to attenuate/eliminate high-frequency artifacts, are disclosed. A distance-driven technique wherein the transitions of the voxels and the detector bins are respectively projected onto a predetermined plane. This projection allows a determination of the contribution of each of the voxels/bins for each of the bins/voxels with lower computation time and improved artifact free images.Type: GrantFiled: January 31, 2003Date of Patent: June 5, 2007Assignee: General Electric CompanyInventors: Bruno Kristiaan Bernard De Man, Samit Kumar Basu

Patent number: 7194109Abstract: A monitor transmits the monitored image signals which have been obtained by imaging subjects to be monitored corresponding to terminals of image signals from a plurality of image pickup apparatuses to the corresponding terminals, respectively. At the terminals, the monitored image signals which have been obtained by imaging subjects to be monitored corresponding to the terminals are respectively received to display the monitored image signals thus received, respectively.Type: GrantFiled: August 28, 2002Date of Patent: March 20, 2007Assignee: Hitachi Kokusai Electric, Inc.Inventors: Yoshifumi Nakamura, Jun Hagiwara

Patent number: 7155050Abstract: A method is provided for comparing multiple samples of cell extract containing a plurality of components. The method comprises the steps of preparing at least two samples of cell extract from at least two groups of cells and of exposing each of said sample of said cell extract to a different one of a set of matched markers, e.g. luminescent markers, to bind the marker to the cell extract to label the cell extract, each marker within said set of markers being capable of binding to the cell extract and can be individually detected from all other markers within said set. The samples are then mixed to form a mixture and said mixture is electrophoresed to separate the components within the cell extract. At least two electronic images of the electrophoresed mixture are obtained (I) by detection of the individual markers, each image being represented by detection of a marker different from the others.Type: GrantFiled: October 31, 2000Date of Patent: December 26, 2006Assignee: GE Healthcare Bio-Sciences ABInventors: Erik Sloge, Tobias Soderman, Lennart Bjorkesten

Patent number: 7142692Abstract: A reproduction equipment converts an identification code of the reproduction equipment into a plurality of signal sequences using a correspondence table and embeds the obtained plurality of signal sequences in AV signals as a digital watermark. A reproduction equipment specifying equipment compares correlation values of the AV signals, containing the digital watermark embedded therein with all signal sequences contained in a correspondence table. A comparison of the correlation values with a previously set threshold value determines the embedded signal sequences and the identification code of the reproduction equipment which may be extracted.Type: GrantFiled: August 29, 2001Date of Patent: November 28, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Koji Arimura, Hisashi Inoue, Kenichi Noridomi, Takashi Katsura, Shinya Kadono, Kazuhiko Nakamura

Patent number: 7139418Abstract: A registration artifact (10) for use in registering two or more fluoroscopic images includes a plurality of radio opaque spheres (12, 14, 16) and a plurality of trackable markers, such as optical reflectors (20, 22, 24 and 26), mounted to a radio transparent body (11). A tracking system locates the position of registrable artifact using the trackable markers for registering the fluoroscopic images with respect to a known frame of reference.Type: GrantFiled: September 25, 2001Date of Patent: November 21, 2006Assignees: Z-Kat, Inc., Biomet Manufacturing Corp.Inventors: Rony A. Abovitz, Brandon D. Larocque, Julio J. Santos-Munne

Patent number: 7123748Abstract: An image synthesizing device is operatively coupled to a plurality of cameras to accurately express the color and brightness of a synthesized image photographed. The image synthesizing device is configured to synthesize the images of the cameras by selecting with respect to an observation point on a surface being photographed the camera positioned closest to the observation point, designating the color and brightness values of the observation point photographed by that camera as the color and brightness values of the observation point, and conducting the same processing for the entire surface being photographed. Thus, among the cameras, the image synthesizing device selects the camera that is closest to the observation point and uses the color and brightness values of that camera. This arrangement results in selecting a camera that photographs a small area of the photographed surface per unit pixel. Consequently, a synthesized image having good color and brightness precision is obtained.Type: GrantFiled: August 30, 2002Date of Patent: October 17, 2006Assignee: Nissan Motor Co., Ltd.Inventor: Ken Oizumi

Patent number: 7116799Abstract: The invention relates to an apparatus and a method for the detection of an object moving in the monitored region of a camera, wherein measured values are compared with reference values and an object detection reaction is triggered when the measured value deviates in a predetermined manner from the reference value. In this respect, both the measured values and the reference values are derived from differences which exist between at least two different image regions.Type: GrantFiled: October 9, 2001Date of Patent: October 3, 2006Assignee: Sick AGInventors: Martin Wüstefeld, Georg Plasberg

Patent number: 7116798Abstract: A substrate card, in the form of a Metrocard®, farecard, keycard, passport, boarding pass or the like, presented for controlled gateway passage at an automatic reader, is photographed and the captured card image is digitized. The card then is heated to a point where trace explosive present on the card is subjected to an energetic reaction imparting a char smudge signature. The card is cooled and a second image is captured and digitized. The digitized images are subjected to a subtractor stage resulting in an isolated char smudge signature image possibly in the form of at least a partial fingerprint residue recognizable by a computer. Upon char image detection, which may include a fingerprint matching process, the computer directs the controlled gateway to restrain the card presenter and secure the card as evidence. The card may be pre-coated to avoid ignition and to enhance trace material adhesion.Type: GrantFiled: July 8, 2005Date of Patent: October 3, 2006Inventor: Manmohan Singh Chawla

Patent number: 7113612Abstract: An apparatus for embedding a watermark into contents data includes a parameter converting device for converting a parameter of first contents data to generate second contents data. A mixing device operates for embedding parameter information into the second contents data as watermark information. The parameter information represents a condition of the conversion of the parameter by the parameter converting device. The watermark information may include copyright information.Type: GrantFiled: February 8, 2002Date of Patent: September 26, 2006Assignee: Victor Company of Japan, Ltd.Inventors: Takayuki Sugahara, Masayoshi Nishitani
