Title: Network system incorporating protection paths in the transmission bandwidth of a virtual concatenation signal
Inventor: SHIBASAKI YASUAKI
IPC: H04B10/275
Filed: 2003-06-23
Abstract: In a method for setting transmission routes, the transmission bandwidth is expanded by incorporating in a virtual concatenation signal 29, generated by concatenation processor 25, working paths (from interface 21) and protection paths (from interface 22) provided the protection paths are in a normal standby state. A bandwidth management unit 26 receives the states of working paths and protection paths from the protection control unit 24. The bandwidth management unit then controls the concatenation processor. If the protection paths are in an unusable state (i.e. there is a fault in the protection paths) or in a used state (i.e. there is a fault in the working paths), the bandwidth management unit 26 controls the concatenation processor 25 to construct the virtual concatenation signal 29 with only paths that can be used in virtual concatenation. The state of paths may be indicated by providing an alarm indication signal on protection paths which are in an unusable state or a used state (see Fig. 5). This invention is particularly suited to SDH or SONET networks.

Title: Apparatus and method for producing a video message
Inventor: SMITH STEVEN ROBERT
IPC: H04N5/85
Filed: 2002-10-17
Abstract: An apparatus for producing a video communication, comprising a video camera 110 for viewing the user U, a processor 112 for presenting instructions on a display 116, a video recording means 118 and means for validating prepayment. A recording medium D, such as a recordable CD or DVD, is presented to the recording means 118 by the user. The system checks that payment has been received, either by reading a bar code on the disk, or by the user entering a code, or by accepting direct payment via cash or credit card. The user then records a video message which is written to the video recording medium. Upon completion of the recording, the recording medium is delivered to the user. A written message may also be included with the video communication. An alternative embodiment employs a disc handling mechanism 20 which utilises a suction arm (250) to transfer an unrecorded disc from a store (254) to the recording means 18 and, upon completion of the recording, to the user through the vending aperture 22.

Title: Bathwater temperature sensing alarm
Inventor: MORRIS PHILIP IAN
IPC: G08B21/18
Filed: 2003-12-04
Abstract: A water-temperature-sensing alarm, contained within a buoyant vessel, that comprises of appropriate electronic components, powered by battery(ies), which can carry out a series of bath-water-temperature tests to give an audible and visible indication. From a stand-by mode, the device will detect its presence in a conductive fluid (bathwater in this case), apply electrical power to other components on the circuit board, and emit an appropriate sound and light sequence. Temperature probes set in the vessel will detect the temperature of the water and instigate another appropriate sound and light sequence. If the water temperature is at an optimum temperature, the sound and light sequence will continue during the time the temperature remains at optimum. If the temperature rises above the optimum a louder sound, and more intensive light sequence, is emitted to provide a warning to the responsible person/guardian/parent that the other person in, or about to be placed in, the bath-water could be in danger of suffering scald burns. The alarm device can also be programmed to detect the temperature of water below a given temperature and emit an audible and visible alarm sequence to warn the responsible person/guardian/parent that the person in the bath-water could be in some discomfort or even in danger of suffering from hypothermia. Once removed from the bath-water the device detects the absence of conductive fluids and reverts to a stand-by mode.

Title: Fluid density measurement in pipes using acoustic pressures
Inventor: GYSLING DANIEL
IPC: G01N9/00
Filed: 2002-11-05
Abstract: The density of at least one fluid in a pipe is determined using a pair of effective sound speeds a1eff and a2eff of the fluid/pipe system. The pair of effective sound speed measurements is taken at two sensing regions along the pipe wherein each of the sensing regions has a different cross sectional area compliance. The pair of effective sound speeds a1eff and a2eff is provided to signal processing logic (60), which determines the density of the fluid flowing in the pipe. The effective sound speeds a1eff and a2eff may be provided by a pair of sound speed meters positioned at the sensing regions wherein the sound speed meters utilize a spatial array of acoustic pressure sensors placed at predetermined axial locations along the pipe. The acoustic pressure sensors measure one-dimensional planar acoustic waves that are lower in frequency (and longer wavelength) signals than those used for ultrasonic flow meters, and thus is more tolerant to inhomogeneities in the flow. In addition, no external acoustic source is required and the meters may operate using passive listening.

Title: Seismic wavefield extrapolation
Inventor: REN JIAXIANG
IPC: G06F17/00
Filed: 2005-05-20
Abstract: A method for seismic wavefield extrapolation in 3D explicit finite difference migration comprises extrapolating 43 a wavefield using variable extrapolation step size; and applying phase-shifted linear interpolation 44 to the extrapolated wavefield. The variable extrapolation step size may be determined dynamically by requiring the wavenumber of the wave component being migrated to satisfy the aliasing condition. The invention utilises variable extrapolation step size in order to maximise the extrapolation interval during each extrapolation step and thus reduce the total number of extrapolation steps required, thereby reducing the overall computational cost of depth migration.

Title: Surface cleaning apparatus
Inventor: HAMILTON SHEILA
IPC: B08B1/00
Filed: 2004-07-28
Abstract: The invention relates to surface Cleaning apparatus for removing contamination from sheet materials such as phototools and liquid crystal display(LCD) screens. The apparatus comprises a base unit (10) having opposing walls (16) for supporting a removeable roller cartridge (12) containing at least one cleaning roller (36) and one adhesive roller (40). Progressive insertion of the roller cartridge (12) into the base unit (10) causes a camming mechanism provided on the base unit (10) and the roller cartridge (12) to interact so as to move the cleaning and adhesive rollers (36, 40) from a non-operating position in which the rollers (36, 40) are separated into an operating position in which the adhesive roller (40) is brought into abutment with the cleaning roller (36). The apparatus is held in the operating position by a latching mechanism, for example an electromagnet (34) which may be selectively activated and deactivated simultaneously with activation and deactivation of a driving motor (18). The features of the invention ensure that the transferring of adhesive from the adhesive roller (40) to the cleaning roller (36) is automatically prevented when the rollers (36, 40) are stationary, even in the event of a power failure.

Title: Generating acoustic signals for well logging
Inventor: LEGGETT JAMES V III
IPC: G01V1/44
Filed: 2004-08-13
Abstract: A logging tool has an acoustic source produces an acoustic signal (Stoneley wave, tube wave, guided wave) within a drill collar or fluid conduit, or in the annulus between the drill collar and the formation. When the acoustic signal reaches a discontinuity in its path (e.g. obstruction inside or outside the collar, hole size variation, formation change, bottom of the hole), part of the wave is radiated into the formation. A receiver receives a signal produced by the interaction of the radiated signal with the formation. The received signal may be subject to semblance processing to determine characteristics of the formation (e.g. earth formation boundaries).
