Patent number: 6650427Abstract: Methods and apparatus are provided for printing and validating a document, such as a ticket or voucher printed on a substrate such as paper. After the document is printed, at least a portion thereof is read to test a validity criteria. The document is dispensed to a recipient if the validity criteria is met. If the validity criteria is not met after the first read, the document can optionally be re-read. If the validity criteria is never met, the document is voided. The voided document can be held or dispensed to the recipient and a replacement document can be printed, read for validation purposes and dispensed. If the replacement document is not valid, it is voided. A voided replacement document can be either held or dispensed. Assistance from a machine attendant is required only in the event that a predetermined number of invalid print/read/validate cycles occur.Type: GrantFiled: October 22, 2001Date of Patent: November 18, 2003Assignee: TransAct Technologies IncorporatedInventors: Donald E.

Patent number: 6645208Abstract: The invention relates to a method and apparatus for immobilizing adjacent bone segments. An osteosynthesis plating system is provided for fixing or immobilizing several pieces or segments of bone utilizing screws which may be screwed into the segments of bone through openings provided in the osteosynthesis plate. The osteosynthesis plate is pressed against the bone surface by the screws and fixed thereto. In particular, the invention relates to an osteosynthesis extension plate for immobilizing adjacent segments of bone in a second surgery wherein the removal of a previously implanted osteosynthesis plate is avoided. In this manner the disadvantages associated with removal of the previously implanted plate are avoided.Type: GrantFiled: September 3, 2002Date of Patent: November 11, 2003Assignee: Aesculap AG & Co.

Patent number: 6647149Abstract: Methods and apparatus are provided for securely transmitting and processing digital image data for display. The invention provides for decomposing, compressing, and scrambling digital image data and forwarding the decomposed, compressed and scrambled image data to a destination where the image data is decompressed, re-composed, and descrambled prior to display. In particular, digital image data is scrambled before or after being compressed and is subsequently descrambled after being decompressed and prior to display such that unauthorized use of the image content is prevented. The invention can be used in conjunction with most standard block-based image compression algorithms such as JPEG as well as some types of wavelet transform based systems.Type: GrantFiled: January 3, 2001Date of Patent: November 11, 2003Assignee: Electronics for Imaging, Inc.Inventors: Richard A.

Patent number: 6647061Abstract: A transcoder architecture that provides the lowest possible complexity with a small error, e.g., for converting an MPEG-2 bitstream into an MPEG-4 bitstream. The transcoder reads header information from an input bitstream and provides a corresponding header in the new format for the output bitstream. In one embodiment, a low complexity front-to-back transcoder (with B frames disabled) avoids the need for motion compensation processing. In another embodiment, a transcoder architecture that minimizes drift error (with B frames enabled) is provided. In another embodiment, a size transcoder (with B frames enabled) is provided, e.g., to convert a bitstream of ITU-R 601 interlaced video coding with MPEG-2 MP@ML into a simple profile MPEG-4 bitstream which contains SIF progressive video suitable for a streaming video application. For spatial downscaling of field-mode DCT blocks, vertical and horizontal downscaling techniques are combined to use sparse matrixes to reduce computations.Type: GrantFiled: June 9, 2000Date of Patent: November 11, 2003Assignee: General Instrument CorporationInventors: Krit Panusopone, Xuemin Chen

Patent number: 6643707Abstract: The Domain Name System (DNS), which has been used for mapping names to Internet Protocol (IP) addresses, is adapted to a broadcast environment, such as a broadband cable or satellite television network. A number of master files are stored on a broadcast name server that define zones of domains in a domain name space, which may include a television-related domain, with sub-domains for different service providers (e.g., ABC, HBO), and a cable domain, with sub-domains for applications, administrative functions and operating system-functions, e.g., at a set-top terminal. The television sub-domains may have their own sub-domains. For example, “ABC” may have the sub-domains “NEWS”, “WEATHER”, and “SPORTS.” The master files are used to form broadcast resource records, which include an identifier for broadcast services (e.g., “ABC”) or other data sources, and which are transmitted to end user terminal devices periodically, or in response to a query.Type: GrantFiled: February 14, 2000Date of Patent: November 4, 2003Assignee: General Instrument CorporationInventor: Robert C.

Patent number: 6643327Abstract: A system for rate control during transcoding and encoding of digital video data in a multi-program transmission environment accommodates changes in the GOP structure of any of the programs, e.g., due to a commercial insertion or the like. A hierarchical bit allocation scheme is used, where bits are allocated on a super group of pictures (GOP) level, i.e., a grouping of multiple GOPs, a super frame level, and an individual frame level. The bit allocation for the super GOP and each picture is adjusted when a change in the structure of a group of pictures (GOP) is detected for any of the pre-compressed programs. The super GOP length may also be adjusted if required to maintain an integer number of GOPs therein. A change in the GOP structure is detected based on a change in the GOP length or sub_GOP length (distance between P pictures). For pre-compressed data, initial GOP lengths and sub_GOP lengths can be assumed and adjusted as required based on actual measurements.Type: GrantFiled: May 5, 2000Date of Patent: November 4, 2003Assignee: General Instrument CorporationInventor: Limin Wang

Patent number: 6622944Abstract: A two phase fuel oil atomizer utilizing a secondary media such as high pressure steam or air to assist in the atomization of heavy fuel oil, while reducing NOx and other polluting emissions. The fuel oil atomizer comprises a mixing plate and a sprayer plate which are configured to discharge atomized fuel oil at varying spray angles in order to provide staging of the atomized fuel as it exits the sprayer plate with the surrounding combustion chamber air to provide a fuel/air ratio that is appropriately rich and lean in order to allow lower flame temperatures. NOx generation is accordingly reduced at the lower flame temperatures. With atomized fuel droplet size small enough to enable rapid fuel evaporation and complete combustion, low CO, opacity and particulate generation are achieved with minimum excess oxygen.Type: GrantFiled: April 20, 2001Date of Patent: September 23, 2003Assignee: Combustion Components Associates, Inc.Inventors: John F.
