Title: Decoding punctured codes
Inventor: GOLDING PAUL ADRIAN
IPC: H04L1/00
Filed: 1995-10-02
Abstract: Contiguous frames of data 70-72, each encoded at a different coding-rate, are sequentially received by a decoder and then converted to a constant K/n code-rate by inserting symbol markers (74-77) at appropriate, punctured bits in each frame. In response to identifying a number of such symbol markers during a predetermined time, an appropriate branch metric calculation is selected and applied by the Viterbi decoder to decode the frame, see also Fig.6 (not shown). The frames are convolutionally encoded for forward error correction in a GSM communication system.

Title: Semiconductor read-only memory device
Inventor: WEN JEMMY
IPC: H01L27/112
Filed: 1997-05-16
Abstract: The ROM (read-only memory) device is formed by by a method which allows for better planarization of the wafer surface of the ROM device with increased gap fill capability. Further, the bit lines are formed by forming a substantially grid-like structure including a plurality of substantially parallel-spaced first portions 49a,49b oriented in a first direction and a plurality of substantially parallel-spaced second portion 50a-f oriented in a perpendicular direction. The first portions serve as bit lines and the second portions serve as channels. In the code-definition and implantation process, a selected number of the channel regions are diffused with impurities so as to set the associated memory cells with a first threshold voltage representing the storage of a first binary digit; while the threshold voltage of all the other channel regions that are not diffused with impurities are set to a second threshold voltage representing the storage of a second binary digit. In the method of fabricating the ROM device, the bit lines are not formed by diffusing impurities into the silicon substrate. As a result of this, the drawbacks of lateral diffusion, junction leakage, and reduced breakdown voltage are not experienced when the ROM device is further miniaturized.

Title: Method and apparatus for measuring the intensity of a beam of light
Inventor: SARKIES JULIAN RICHARD
IPC: G01J1/04
Filed: 1999-03-16
Abstract: Apparatus for measuring the intensity of a light beam with reduced sensitivity of the detected light intensity value to both the position of the spot on a window 18 of the device and the angle of incidence of the beam, comprising means 52, 54, 60, 66, 68, 74, 76 for scattering the incident light and a detector 50 for detecting the intensity of the scattered light. Optical scattering and/or attenuator means 44, whose attenuation decreases from the centre to the edge, is provided between the window and the detector. The area of the window may be many times the area of both the beam and the detector. Further attenuator means 48, which may take the form of an optically opaque material, e.g. thin stainless steel, having apertures sufficiently larger than the wavelength of the light for transmitting an attenuated portion of incident light, attenuates the light intensity after preliminary scattering. Provision of surface scattering elements in advance of the bulk scattering elements reduces the risk of damage to the bulk scattering elements. The attenuation and scattering means may be provided by disks with a varying distribution of holes (figures 4 and 9) or varying thickness (figure 8).

Patent GB-2337895-A (GB)
Title: Detecting congestion in ATM networks
Inventor: CURTIS MARC SIMON
IPC: H04L12/56
Filed: 1995-06-05
Abstract: Congestion detection apparatus, for use in an ATM network, includes a first circuit (32) arranged at an ingress node (54) and a second circuit (33) arranged at an egress node (58) of the network. The first circuit (32) transmits a timing cell to the second circuit (33) via a virtual channel of the network. The second circuit determines the time of receipt of the timing cell concerned. The timing cell carries timing information indicating the time of transmission of the cell concerned by the first circuit. This timing information is not modified as the cell passes through intermediate nodes of the network between the ingress and egress nodes. A measure of end-to-end delay experienced by ATM cells of the virtual channel concerned is determined in dependence upon the time taken for the timing cell to travel from the first circuit to the second circuit. Congestion in the virtual channel concerned is detected based on the determined measure of end-to-end delay.  In such apparatus the end-to-end delay is determined using circuitry provided exclusively at the ingress and egress nodes, without the involvement of any intermediate node.

Abstract: A multi-layer editing system adapted to perform fast composition, special effect and editing processes of plural-channel video data supplied in a multi-layer format. On a display device of a work station in the editing system, there is displayed a graphical user interface (GUI) having a time line (46) and an object area (47). The time line consists of a multi-layer structure (L1-L4) to conform with a plurality of channels for generating one edited video clip by compositing plural-channel video clips. The object area is used for displaying objects (101-104) which represent the linked state of the clips displayed in the individual layers of the time line. More specifically, the objects are icons for defining the process (composition, editing or special effect) by the use of the clips assigned to the layers. The objects are so displayed as to correspond to the layers and the clips respectively. And in accordance with such objects, the editing system performs special effect, editing and composition processes of the plural-channel video data supplied from a disk recorder.

Title: Ferroelectric acousto-optic devices
Inventor: PANNELL CHRISTOPHER NOEL
IPC: G02F1/11
Filed: 1999-09-23
Abstract: An acousto-optic tuneable filter comprises a ferroelectric crystal in which domain inverted regions R1, R2 have been created by electric field poling. Preferably, the spacing of the domain inverted regions varies along the length of the crystal. The domain walls are not normal to the x-face of the crystal. Acoustic waves may be generated in the crystal by applying rf power to electrodes situated on one or other of the faces of the crystal. Once generated the acoustic waves cause coupling between polarisation eigenstates of the crystal. The polarisation state of an input light beam is altered by the acoustic wave such that certain frequencies of can be separated from the rest by polarisation optics.

Title: Current optimised dual band patch antenna
Inventor: LANGLEY RICHARD JONATHAN
IPC: H01Q5/10
Filed: 1999-09-30
Abstract: A dual band patch antenna comprises a ground plane 30 and a patch, parallel to the ground plane and having first 32 and second portions 34 whose resonant frequencies define the two operating bands, which is shaped so as to substantially correspond to current paths that signals within the bands would induce in the patch without such shaping. Preferably the ground plane is also shaped using such a technique and the ground plane and first potion are fed via a coaxial cable 38. Preferably one end and the sides of the patch are aligned with the edges of the ground plane and the patch and ground plane are formed on either side of a printed circuit board. One patch resulting from this method of current optimisation has a second portion comprising two elongate patches 34, half the width and half the length of the first portion, which are connected 36 to the ground plane and placed either side of the first portion. The shaping also results in the first portion of the patch being H-shaped (32, Figure 5), and the ground plane being provided with two apertures (Figure 5). Other structures resulting from this method give rise to apertures in the patch (Figures 7 and 8) and alternate shaped first portions (Figure 13).
