Patent number: 7406211Abstract: In CT (computed tomography) images, streak artifacts caused by the presence of metal implants and inhomogeneous estimation of tissue density are reduced or eliminated.

The optical actuator moves a guide between a retracted and an extended position relative to an actuator body. The actuator body has a channel, or through-opening, in which the mirror guide moves. In one embodiment, the channel has a two flat surfaces that form a portion of a v-groove in the channel. In the extended position, the guide contacts a stop pin, or stopper, and the two flat surfaces in the through-opening, thereby holding the guide in a position defined by the line of contact between the stop pin and an angled surface of the guide and a pair of parallel contact lines where the guide contacts the two flat surfaces in the through-opening.Type: GrantFiled: May 3, 2005Date of Patent: July 29, 2008Assignee: Neptec Optical Solutions, Inc.Inventor: John Carberry

Patent number: 7406247Abstract: Devices, systems and methods for thermal testing of optoelectronic modules are disclosed. The device includes a frame member, a thermoelectric cooler, a plate in thermal contact with the DUT, a heat sink in thermal contact with the frame, and a metallic clip for attaching the thermal testing device to the module (DUT). The clip secures the thermoelectric cooler to the DUT. The method includes the steps of providing a testing apparatus having a printed circuit board with a test circuit formed thereon. The test board also has an electrical interface disposed in electrical communication with the test circuit, and a thermal testing assembly. A temporary electrical connection is formed between the DUT device and the interface. The thermal testing assembly is used to maintain a test temperature of the DUT device. A data stream is transmitted through the DUT device and then evaluated for adherence to a defined specification.Type: GrantFiled: August 13, 2007Date of Patent: July 29, 2008Assignee: Finisar CorporationInventors: Samantha R. Bench, John C. Dirkson, Darin James Douma

Patent number: 7406248Abstract: The present invention relates to the retrieval and storage of image data captured using a digital image acquisition device such as a still camera, a video camera or a scanning device, and of image data stored on removable storage media such as compact flash, smart and memory stick media. An image retrieval architecture is described such that image data may be retrieved from any digital image acquisition device and/or from removable storage media, and a “one-click” operation is available to minimize an amount of interaction needed to retrieve image data from the digital image acquisition device.Type: GrantFiled: November 28, 2000Date of Patent: July 29, 2008Assignee: Canon Kabushiki KaishaInventors: Abhijit B. Rao, Donald P. Gibson, Brian M. Keane, Jr., Lionel Gregory Croom, Costin Valeriu Cozianu, Douglas Richard Barr, Paul Gacek

Patent number: 7406250Abstract: With this invention, at least one of a video file containing video information, a still picture file containing still picture information, and an audio file containing audio information and a management file having management information on a control method of reproducing the information in the file are recorded on an information storage medium. This realizes a data structure that causes the recording and deleting places on the information storage medium to correspond spuriously to places on a single tape, such as a VTR tape. Use of the data structure provides users with an easy-to-use interface.Type: GrantFiled: January 29, 2002Date of Patent: July 29, 2008Assignee: Kabushiki Kaisha ToshibaInventors: Hideo Ando, Hiroaki Unno

Patent number: 7406252Abstract: DVD-video data and DVD-audio data are recorded in a DVD-Avd disc. The DVD-audio data is composed of an audio manager having an audio manager information, an audio manager menu, a first audio title set including first audio data and a second audio title set including second audio data. The first audio data of the first audio title set is connected with audio contents included in the DVD-video data, and a real time information (RTI). pack or a still picture (SPCT) pack is included in the second audio title set. Therefore, the audio contents of the DVD-video data and the audio data of the DVD-audio data are managed by the audio manager information, and text information indicated by real time information or a still picture is displayed while reproducing the audio data. Also, DVD-video data recorded in a DVD-video disc, which is normally reproduced by using a reproducing apparatus dedicated to the DVD-video disc, can be reproduced by using a reproducing apparatus for the DVD-Avd disc.Type: GrantFiled: June 17, 2003Date of Patent: July 29, 2008Assignee: Victor Company of Japan, Ltd.Inventors: Yoshiaki Tanaka, Shoji Ueno, Norihiko Fuchigami

Patent number: 7406253Abstract: When a recording start executed in a variable-speed recording mode, at ST44 a signal having a variable frame rate is selected on the basis of a validity signal from among image signals having a predetermined output frame rate in which the images having the variable frame rate are contained and stored in a memory. If it is decided at ST46 that a phase difference between a write position and a read position in the memory has reached a recording start level, the stored signal is recorded in a recording medium at ST47. If it is decided at ST48 that the phase difference has decreased to a recording stop level, recording to the recording medium is stopped at ST49. When an end operation is executed at ST51, the signal in the memory is recorded in the recording medium to then end actions. The signals are selected and recorded, thus resulting in a smaller signal quantity. Further, if the variable frame rate is varied, video effects can be confirmed only by reproducing the recorded signals.Type: GrantFiled: April 3, 2003Date of Patent: July 29, 2008Assignee: Sony CorporationInventors: Yoshihito Ueda, Hiromi Hoshino, Tomokiyo Kato, Kaoru Urata, Mikio Kita
