Title: Resource reservation in 3G or future generation Telecommunication Network
Inventor: CHEN XIAOBAO X
IPC: H04L47/80
Filed: 2001-01-22
Abstract: A method of reserving resources in third or future generations of wireless mobile networks such as Universal Mobile Telecommunications Systems (UMTS), characterised by sending either the data object contents or the entire contents of a Quality of Service (QoS) request in Resource Reservation Protocol (RSVP) messages.

Title: Methods of iterative categorisation for managed ubiquitous delivery of infor    mation and transactions across differentiated channels
Inventor: ROSS GORDON
IPC: G06Q30/00
Filed: 2001-06-04
Abstract: With the continuing developments in content delivery of multi-media forms, to an increasing array of devices, across a series of discrete media channels, there is potential for duplication, confusion and information overload for users. Information confusion and congestion are also possible outcomes of discrete ownership of different content, media and transmission channels. To overcome these difficulties requires a new paradigm of co-operation between content, computing and communications through the development of shared standards and methods, particularly with regard to human-computer-content interfaces. This novel method demonstrates how to exploit cyclical categorisation to build information and group processes and structures to deliver effective content creation, delivery, user assimilation and interactivity, as well as communications and commerce transactions. Novel methods are described for achieving co-ordination between different media channels, improving overall usability, assimilation and experience with information and interaction. With such co-ordination new opportunities are opened up for interactive information and transaction services.

Title: Non-invasive method for determining diastolic blood pressure
Inventor: HERSH LAWRENCE T
IPC: A61B5/022
Filed: 2002-09-10
Abstract: The blood pressure of a human being is measured by a method which places an inflatable cuff 12 around a portion of the body. The cuff is inflated to a predetermined pressure which occludes the flow of blood, and is then deflated in a controlled manner. At a plurality of deflation pressure levels, pressure oscillations in the cuff are measured by a transducer 24 producing a pressure oscillation waveform. Estimates of the mean arterial pressure (MAP) and systolic pressure are found by examining the variation of the peak-amplitudes of the oscillation waveform with cuff pressure. A portion of the waveform, taken at sub-diastolic pressure, representing one cardiac cycle is then analysed and calibrated by locating points which correspond to systolic, diastolic and mean arterial pressures. Diastolic pressure is then derived as a function of those points and the earlier estimates of the MAP and the systolic pressure.

Title: Brake pressure modulation valve housing block having an integral hollow column
Inventor: SCHWIND BARBARA
IPC: B60T8/36
Filed: 2002-09-13
Abstract: A known housing block for a hydraulic vehicle brake system has pressure modulation valves incorporated in one side of the block and at least one pressure measuring element is associated with that side of the block, the pressure measuring element being spaced from the block and communicating with a channel present in the block by means of a tubular element which damps pressure pulses. The tubular element has to be sealed with an opening of the housing block to prevent leaks. To prevent leaks, the invention proposes constructing a tubular element in one piece with the housing block 2, the tubular element being in the form of a hollow column 6 with a bore 9. The column supports the pressure measuring element 10 and is hydraulically connected to the channel 4 in the housing block 2. The bore 9 may be formed when the block is manufactured from molten material eg aluminium, or may be drilled. An alternative embodiment has the a connecting piece (14a, fig 2) self-clinching or self-caulking to the column.

Title: Beam shut-off in a laser scanning microscope
Inventor: SCHOEPPE GUENTER
IPC: G02B21/06
Filed: 2002-09-27
Abstract: A laser scanning microscope 100 contains moving mirrors 3,4 to enable a laser beam to scan an object 10 in a raster fashion. In order to prevent the beam from irradiating the target when not required the beam is directed onto a beam blocking device or 'stop' 6 which prevents the light from reaching the target scanning area. The stop may be arranged in a frame shape which surrounds the scanning area to enable the beam to be easily deflected for shut-off at any point during the scan. The use of the stop is a cheap alternative to more expensive methods employing acousto-optical modulators.

IPC: C04B38/06
Filed: 2003-09-22
Abstract: A lightweight aggregate is formed from a mixture of inorganic material such as power station waster ash, river dredgings, mine tailings, industrial or chemical waste, and organic material, such as sewage, agricultural waster or domestic garbage. Preferably the aggregate contains 70% inorganic materia and 30% organic material. The starting materials are mixed together and pelletised. The pellets are hardened by rolling and polishing before drying at temperatures between 100{C and 300{C. The dried pellets are then heated at between 400{C and 800{C to burn off organic components near to surface of the pellet. The pellets then undergo a final heating stage in a rotary kiln at around 1250{C. Remaining organic components are volatilised and a lightweight aggregate bead is produced.

The object and reference beams are directed, by interface optics 14, onto a detector array 21 in overlapping fashion such that they interfere on the array, the optical path difference between the reference beam and object beam varying across the array. Also claimed is the transverse scanning of the target with the object beam and, for each image point, storing a subset of data points and subsequent depth processing and display. The array may be a CCD linear array. The path length may be adjusted via displaceable mirrors 23; polarisation of both returned and reference beams may be controlled 17, 18.
