Title: Information recording device and method, information reproducing device and method, recording medium, program, and disc recording medium
Inventor: KOBAYASHI SHOEI
IPC: G11B20/12
Filed: 2003-01-24
Granted: 2012-12-11
Abstract: An ECC block is constituted by RS(248,216,33). Of a data length of 216 bytes (symbols), only 16 bytes are allocated to BCA data and the remaining 200 bytes are used for fixed data having a predetermined value. Using the fixed data of 200 bytes and the BCA data of 16 bytes, parities of 32 bytes (symbols) are calculated. Only the BCA data of 16 bytes and the parities of the former 16 bytes of the 32-byte parities, that is, a total of 32 bytes only, are recorded in a burst cutting area of an optical disc. In decoding, error correction processing is carried out by using the fixed data of 200 bytes. The unrecorded parities of 16 bytes are processed as having been erased. Thus the error correction capability in a burst cutting area of an optical disc can be improved.

Title: A method of operating a mass spectrometer to suppress unwanted ions
Inventor: TANNER SCOTT D
IPC: H01J49/00
Filed: 2002-05-09
Granted: 2010-10-05
Abstract: In a mass spectrometry system, a method of operating a processing section, for example a collision cell, is provided. The method is based on the realization that some interfering ions after collision will have significantly lower kinetic energy than desired analyte ions. These interfering ions can be ions originating from the source, or product ions formed by reaction with gas particles, or ions produced by other processes within the cell. Significantly, these interfering ions can have lower kinetic energies, as compared to desired analyte ions, but this energy differential disappears, or is much reduced, at the exit of the collision cell, rendering post-cell energy discrimination less effective. The invention provides a field within the cell to discriminate against the interfering ions based on their lower kinetic energy.

Granted: 2008-09-02
Abstract: A sealing technique is provided for forming complex and multiple seal configurations for fuel cells and other electrochemical cells. To provide a seal, for sealing chambers for oxidant, fuel and/or coolant, a groove network is provided extending through the various elements of the fuel cell assembly. A  source of seal material is then connected to an external filling port and injected into the groove network, and the seal material is then cured to form the seal.    There is thus formed a "seal in place", that is robust and can be bonded, where possible, to individual elements of the fuel cell assembly. This avoids the difficulty, labor intensive cost and complexity of manually assembling many individual gaskets into complex groove shapes and the like. The seal material can be selected to be compatible with a wide variety of gases, liquid coolants and the like.

Title: Accelerometer
Inventor: MILLER SCOTT A
IPC: G01P15/125
Filed: 2002-10-16
Granted: 2009-12-22
Abstract: An accelerometer (100) comprising a silicon wafer is etched to form a fixed portion (400), a movable portion (300), and a resilient coupling (120) between, the fixed and movable portions generally arranged in the plane of t he wafer, the mass of the movable portion being concentrated on one side of the resilient coupling. One of the fixed and moveable portions of the silicon structure includes a first electrode. The other of the fixed and moveable portions includes a second electrode oriented parallel to the axis of acceleration, and an electrically-conductive layer electrically connected as a third electrode coplanar and mechanically coupled with the second electrode. The second and third electrodes are arranged in capacitive opposition to the first electrode, the capacitance between the first electrode and third electrode increasing as the movable portion moves in a direction along the axis of acceleration relative to the fixed portion and decreasing as the movable portion moves in an opposite direction. A resilient coupling retains the first and third electrodes in capacitive opposition to each other across a capacitance gap while allowing motion of the first electrode relative to the second and third electrodes in response to acceleration along an axis of acceleration perpendicular to the plane of the wafer, and resiliently restor es the first electrode to an equilibrium position when the acceleration ceases. The second electrode is in opposition to a majority of the surface area of t he first electrode when the electrodes are in the equilibrium position. Capacitance between the first and third electrodes is measured to obtain a measurement of acceleration along the axis.

Granted: 2010-08-03
Abstract: An apparatus for controlling the barking of a dog through application of a spray deterrent, or spray control bark collar. The spray control bark collar administers a dose of a pressurized substance in response to the barking of the dog. The spray control bark collar detects the barking of the dog through the measuring of vibrations produced by the dog. In addition, the spray control bark collar delivers successively larger doses of the spray deterrent to the dog to deter the dog from further barking should the dog fail to respond to previous deterrent attempts. Finally, the spray control bark collar monitors the usage of the spray deterrents to gauge the amount of the deterrent substance remaining in the deterrent substance reservoir.

Abstract: Selon l'invention, des individus partagent de la musique par l'intermédiaire de dispositifs audio portables lisant la musique de manière synchronisée, par la transmission de signaux musicaux d'un dispositif à un autre. Après en avoir fait la demande, d'autres individus peuvent devenir membres de ce groupe de partage de musique. Ces nouveaux membres peuvent être acceptés soit automatiquement, soit par un vote effectué par les membres du groupe existants. Pour que les membres d'un groupe puissent converser, la part de son ambiant admis par les écouteurs du dispositif portable peut être réglée manuellement. Pour améliorer l'écoute, des transducteurs portables, tels que des diodes émettrices de lumière, répondent à des signaux associés aux battements de la musique. Ces signaux peuvent être produits automatiquement ou déterminés manuellement, et ils sont ensuite stockés pour être lus avec la musique à laquelle ils sont associés. Des transducteurs portables associés à des individus participant à un grand événement musical peuvent être réglés pour recevoir des signaux communs, de sorte que lesdits transducteurs répondent en synchronisation les uns avec les autres.
