Abstract: Digitized information can be automatically re-edited to alternate sequence characteristics or lengths with a marker file provided to a computer. Information that can change the characteristics of the digitized information is contained in the marker file and is a variable that can automatically control the digitized information stored in the memories. The disclosed procedure involves assigning identification markers for points in a digital information file of a certain length containing digitized information.  The markers may be assigned relative to the frame number from the beginning of the digital information file. The sections defined by the markers are then re-assembled automatically in other orders, output characteristics or in other sequences to create a new digital information file of different structure, characteristic and length.  The technique is especially useful for producing musical rearrangements in the cathode ray tube screen and audio synthesizers.

Granted: 2001-10-23
Abstract: An apparatus and method for the treatment of diseases of the prostate, including BPH and prostate cancer, utilizing transurethrally applied focussed ultrasound energy to produce hyperthermal and thermotherapeutic effects in diseased tissue are disclosed. A first preferred embodiment of the apparatus relies on visual control; and a second preferred embodiment of the apparatus incorporates an integrated ultrasonic imaging and therapy transducer. The apparatus and method feature the close proximal placement of the ultrasound transducer to the diseased tissue to be treated, resulting in less attenuation of the beam and deposition of a greater fraction of the total emitted ultrasound energy in the selected portion of the diseased tissue. The ultrasoundenergy passes atraumatically through the urethral wall and other tissue not targeted. At the focal point of the ultrasound energy, substantial heating of diseased tissue to produce hyperthermal effects therein occurs, and even higher thermotherapeutic temperatures are attainable to produce coagulative necrosis of diseased tissue.

Granted: 2004-08-03
Abstract: Coupon information is stored in 2 memory at a cable television station. The cable television station may simultaneously transmit multiple video signals, each representing different sources of television programming, over multiple television channels on the cable network. The video signal may at times, such as during a product advertisement or other offer, include an embedded coupon identifier. A coupon subsystem at the cable television station monitors each video signal and retrieves token information from a database when it detects a corresponding embedded token identifier. The coupon information is transmitted over a data channel on the cable network. A subscriber unit at the television viewer's site receives the data channel and extracts the coupon information. The television programming aurally or visually alerts the viewer that a coupon may be generated. If the viewer actuates an input device, such as a button on a television remote control, a printer generates a coupon bearing the coupon information.

Title: An optimal soft-output decoder for tail-biting trellis codes
Inventor: ANDERSON JOHN BAILEY
IPC: H03M13/41
Filed: 1997-04-14
Granted: 2004-10-12
Abstract: A circular MAP decoder for error-correcting trellis codes that employ tail biting produces soft-decision outputs provides an estimate of the probabilities of the states in the first stage of the trellis, which probabilities replace the a priori knowledge of the starting state in a conventional MAP decoder. The circular MAP decoder provides the initial state probability distribution in either of two ways. The first involves a solution to an eigenvalue problem for which the resulting eigenvector is the desired initial state probability distribution; with knowledge of the starting state, the circular MAP decoder performs the rest of the decoding according to the MAP decoding algorithm. The second is based on arecursion for which the iterations converge to a starting state distribution. After sufficient iterations, a state on the circular sequence of states is known with high probability, and the circular MAP decoder performs the rest of the decoding according to the MAP decoding algorithm.

Abstract: An apparatus and method for two-sided printing on items such as mail pieces. A printing station includes an ink jet printhead which is spaced from a transfer roller. As the roller rotates the printhead forms a first image on the surface of the roller. A mail piece or other item to be printed is feed through the printing station to pass between the printhead and the roller with the timing control so that the mail piece makes tangential, rolling contact with the transfer roller just as the image is completed on the roller and the image is then transferred from the roller to one side of the mail piece as the mail piece continues through the printing station by an offset printing process. As the mail piece passes between the roller and the printhead the printhead is controlled to print a second image on the opposite side of the mail piece.

Title: Catalyst, process for its production and its use for preparing vinyl acetate
Inventor: DINGERDISSEN UWE
IPC: B01J23/48
Filed: 1998-06-04
Granted: 2006-08-01
Abstract: The invention relates to a process for producing supported shell catalysts comprising noble metals by UV photoreduction of noble metal salt precursors fixed to a support. For this purpose, the shaped supported body is impregnated with suitable noble metal salts which are then reduced to the metals in a zone close to the surface by means of UV radiation, preferably in the absence of a chemical reducing agent. The metal salts in the interior of the pellets which have not been irradiated and therefore have not been reduced are extracted using a solvent.       The noble metal shell catalysts produced in this way can be used for many heterogeneously catalyzed reactions such as hydrogenations and oxidations.       According to the invention, Pd/Au shell catalysts on porous ceramic supports, e.g. SiO2 shaped bodies, produced by this process can be used in the synthesis of vinyl acetate.
