Title: Forward link transmission power monitoring
Inventor: MATSUKI TORU
IPC: H04J13/00
Filed: 2001-04-24
Abstract: The monitor section monitors a forward-link transmission power value radiated to the mobile station. When the forward-link transmission power value becomes smaller than a predetermined steady output value, the calculating section calculates system parameter information of the mobile station, which corresponds to the reduced forward-link transmission power value. The notification section notifies the mobile station of the system parameter information of the mobile station. The mobile station includes a transmission power control section. When the mobile station in the standby state starts originating/terminating operation to/from the base station, the transmission power control section controls the transmission power value of the reverse-link control channel from the mobile station on the basis of a value obtained from the reception field strength value of the forward-link control channel from the base station and the system parameter information of the mobile station. A transmission power control method for the above system is also disclosed.

According to one aspect of the invention, there is provided a method of watermarking a digital image, comprising: obtaining digital image coefficients; forming a plurality of arrays of image coefficients, each array comprising a predetermined number of image coefficients; selecting a plurality of input values, selected input values each representing binary 0s or 1s; and for each array: determining a binary value as a watermark component bit; calculating a numerical value being representative of the image coefficients; and, if necessary, modifying one or more of the image coefficients, such that the representative numerical value becomes equal to a selected input value which represents the determined watermark component bit. According to other aspects of the invention, there are provided a corresponding method of detecting a watermark, and corresponding hardware and software devices.
Patent GB-2362904-A (GB)
Title: Improved jar mechanism
Inventor: DARNELL DAVID
IPC: E21B31/113
Filed: 2001-05-12
Abstract: A jar mechanism (1, Fig 1) has a jar rod 2 which is releasably secured via a latch key 3 and a latch sub 4 to a piston 5. The piston 5 has a shaft 6 and a body 7. The latch sub 4 is secured to the shaft 6 by a roll pin (8 fig 2). The shaft 6 and body 7 are secured together in a fluid chamber 9 in a piston housing 10. When an upward jar is to be exerted the jar rod 2 is pulled slowly upward. The pulling force exerted on the jar rod 2 is transmitted to the piston 5 via the latch key 3 and latch sub 4 so that the piston 5 is moved through the fluid chamber against the resistance of the fluid. As the movement of the piston 5 is slow due to the restricted fluid flow, time is available to pull up to a desired force before the piston reaches the other end of the fluid chamber 9. Continuation of the pulling force forces the latch key 3 out of the jar rod 2 so that the rod 2 is released from the piston 5 and rapidly accelerates until a shoulder 37 hits the anvil shoulder 11a of the anvil sub (11, Fig 1). This creates the upward jarring force. The jar(1, Fig 1) may then be reset. A balance piston 32 may be provided to accommodate any thermal expansion of fluid in the fluid chamber 9 . Likewise, the jar rod (2', Fig 9A,9B) may also have an acircular cross section which may lodge against faces(202, Fig 9B) in the anvil sub(11', Fig 8B) so that turning forces may be transmitted from the jar rod(2', Fig 9A,9B) to the anvil sub (11', Fig 8B).

Title: Shield for protecting aircraft brake assemblies
Inventor: SWALES PHILIP ARNOLD
IPC: F16D55/36
Filed: 2001-05-17
Abstract: An aircraft brake assembly 1 has components which are sensitive to heat and to contact with substances present in runway de-icers, cleansing fluids and like liquids. The assembly 1 includes an external shield 10 in the form of a rigid or flexible, fluid-impermeable or porous material located to receive and retain such liquids. Heat generated by use of the brake assembly 1 evaporates liquid on the shield 10 or discourages liquid from settling thereon. The shield may be of a porous material such as carded staple fibre sheet, glass fibre, or other fabric; or an impermeable metallic or ceramic material. The shield may be built up of two or three sections rivetted to a pressure stator 11. Thus carbon composite brake discs are protected from higher temperatures and contaminants which otherwise increase the oxidation rate of the brake discs reducing material strength and causing drive tenon failure.

Title: A method of setting the magnetic field of a high temperature superconducting magnet
Inventor: NAKAMURA TAKASHI
IPC: G01R33/3815
Filed: 2001-06-25
Abstract: A method of setting the magnetic field of a high temperature superconducting magnet using a high temperature superconductor positioned inside an evacuated container. The method comprises; a magnetising step (A) in which the superconductor is cooled to a temperature sufficiently lower than its critical temperature for it to be magnetised by an external coil; a magnetic flux setting step (B) in which the temperature of the superconducting magnet is raised to a temperature higher than the magnetisation low temperature but lower than the critical temperature to set a predetermined flux density; and a controlling step (C) in which the temperature is then dropped to an operation range lower than the flux setting temperature so that small temperature fluctuations will not affect the flux density. The method therefore provides a way of forming a magnetic field comparable to one in a conventional superconducting magnet with a flux density that can be accurately chosen and held constant for a long period of time. Such a magnet would be especially useful in an NMR machine.

Title: Carrier phase-based relative positioning apparatus
Inventor: TODA HIROYUKI
IPC: G01S19/44
Filed: 2001-07-23
Abstract: A carrier phase-based relative positioning device comprising a plurality of antennas installed on a mobile unit. The apparatus determines the position of each antenna relative to a reference antenna. This is carried out by receiving radio signals transmitted from a plurality of position fixing satellites S<SP>1</SP> to S<SP>k</SP> multiple antennas, observing a single difference phase or a double difference phase, and calculating an integer ambiguity of the difference phase. The apparatus judges that the integer ambiguity has been incorrectly determined if the position of any of the antennas relative to the reference antenna (or the angle of a flat plane formed by these two antennas) eg inner product, attitude from INS, falls outside a preset range in which the relative position (the angle of the flat plane) falls under normal conditions. In dependant claims, the cross product of each of the baseline vectors is calculated.

Title: Improved lid for a container
Inventor: SAMUEL-BOYD GAYLE
IPC: B65D47/24
Filed: 2000-02-03
Abstract: A lid (14) and a container (12) are disclosed which are ideally suited for drinks and particularly hot drinks such as tea or coffee. The top of the lid (14)/ container (12) has an aperture with a closure (20). When the container (12) is not in use, the closure (20) remains closed. However, a user can, by means of a sliding trigger (22), open the closure (20) whenever they wish to take a drink. This has the advantage of avoiding spillage, while being easier to operate than existing automatic opening arrangements for drinks containers.

Title: Tightly-coupled disk-to-cpu storage server
Inventor: TAYLOR CLEMENT G
IPC: H04N21/218
Filed: 2000-03-30
Abstract: A storage server (110) for efficiently retrieving data from a plurality of disks (212) in response to user access requests. The server comprises a plurality of processors (302) coupled to disjoint subsets of disks, and a custom non-blocking packet switch (220) for routing data from the processors to users. By tightly coupling the processors to disks and employing an application-specific switch, congestion and disk scheduling bottlenecks are minimized. By making efficient use of bandwidth, the architecture is also capable of receiving real-time data streams from a remote source and distributing these data streams to requesting users. The architecture is particularly well suited to video-on-demand systems in which a video server stores a library of movies and users submit requests to view particular movies.
