Title: Apparatus and method for receiving multi-channel caller identification data
Inventor: KIM HONG-HAN
IPC: H04Q3/72
Filed: 1996-06-21
Abstract: An apparatus for receiving multi-channels caller identification data in a switching system is disclosed. A path forming means 54 forms a path in response to an incoming ring signal from each of a plurality of central office lines to receive caller identification data loaded on the ring signal. A multiplexer 56 multiplexes first signals from the path forming means 54 with second signals from the corresponding central office lines. The multiplexed analogue signals are sampled at 8KHz by a CODEC 58 and converted into PCM signals. Time switching means 60 demultiplex the PCM-converted first signals from the PCM-converted second signals and output the PCM-converted second signals to corresponding channels. A digital signal processor 64 receives the PCM-converted first signals from the time switching 60 means and demodulates the caller identification data from a selected first signal. The caller identification data is then displayed.

Title: Aggregate Inernet route switching
Inventor: FELDMAN NANCY KAREN
IPC: H04L45/243
Filed: 1997-10-01
Abstract: IP based networks use a number of different IP routing protocols to determine how packets ought to be routed. However, due to the rapid growth of the Internet, there is a great need for higher packet forwarding performance. This invention describes a way to map IP routing information onto a technology that uses label switching and swapping, such as ATM, without the need to change the network paradigm. This allows a network to continue to function and appear as a standard IP network, but with a much higher performance. In this invention, an Integrated Switch Router (ISR), is a switch that has been augmented with standard IP routing support. The ISR at an entry point to the switching environment performs standard IP forwarding of datagrams, but the "next hop" of the IP forwarding table has been extended to include a reference to a switched path (for example, the VCC in ATM technology). Each switched path may have an endpoint at a neighboring router (Comparable to existing IP next hops on conventional routers), or may traverse a series of ISRs along the best IP forwarding path, to an ISR endpoint. This allows datagrams to be switched at hardware speeds through an entire ISR network.

Title: Receiver for television signals
Inventor: HOLLIDAY DAVID
IPC: H04H20/00
Filed: 1998-06-12
Abstract: A receiver receives television signals in a plurality of channels. Each signal defines a television programme and at least a signal in one of the channels comprises compressed data defining broadcast events in the channels. The receiver produces output signals defining an image of events in the programme schedule for display on a television screen. The receiver receives data defining a dictionary representing text portions, decodes the programme scheduling data to identify text portions in the dictionary, and constructs the image of events from the identified text portions. A signal in each channel comprises a bouquet identity and a sub-bouquet identity for the channel. The receiver stores a reference bouquet identity and one or more reference sub-bouquet identities, compares the bouquet identity and sub-bouquet identity for a channel in a received signal with the reference bouquet and sub-bouquet identities and outputs the received television signal for display of the programme or other services defined thereby depending on the comparison.

IPC: F15B9/08
Filed: 1996-12-19
Abstract: The invention is a multi-stage electro-hydraulic servovalve having a mechanical feedback between the valve's main stage (2) and pilot stage (4). The feedback mechanism makes use of an interconnected set of linkages (74, 82, 88, 96, 98, 116, 112, 66) that transform a linear motion of the main stage slide (6) into a rotative movement of a torque rod (66) that can produce a translation of the pilot stage slide (50). Many of the linkages of the feedback mechanism are located exterior to the valve's fluid boundary and feature readily adjustable connections (98,102,124) through which a user can adjust various parameters of the feedback such as the degree of gain and null point.

Title: Steerable rotary drilling system
Inventor: BARR JOHN DENZIL
IPC: E21B7/06
Filed: 1996-02-14
Abstract: A steerable rotary drilling system comprises a bottom hole assembly which includes, in addition to a drill bit (1), a modulated bias unit (10) and a control unit (9) including a instrument carrier (24, fig. 5) which is rotatable relative to the bias unit (10). The bias unit (10) includes a number of hydraulic actuators (13) spaced around the periphery of the unit, each having a movable thrust member which is displaceable outwardly for engagement with the formation. Each actuator can be connected, through a rotatable control valve (15), to a source of drilling fluid under pressure, the control valve comprising a first part (138), rotatable with the instrument carrier (24, fig. 5), which cooperates with a second part (136) which is rotatable with the bias unit (10). Means are provided to roll stabilise the instrument carrier so that relative rotation between the bias unit and the instrument carrier, as the bias unit rotates, causes the valve (15) to operate the actuators (13) in synchronism with rotation of the bias unit (10) so as to apply a lateral bias thereto. In order to neutralise or reduce the net bias applied to the bias unit (10) the instrument carrier (24, fig. 5) is rotated instead of being roll stabilised. The angular velocity of the carrier (24, fig. 5) is varied during its rotation, according to various formulae, in order to vary the net bias. The net bias may also be varied by alternating different modes of carrier rotation.

Title: Matching basis functions
Inventor: BROWN DEREK WILLIAM
IPC: H04N7/30
Filed: 1998-12-18
Abstract: A set of basis functions is matched to a digital signal which may be a broadcast television signal. The basis functions are used for compression encoding the digital signal by a process known as matching pursuits. This is an iterative process including the steps of correlating coefficients of the basis functions to the input digital data, selecting the basis function having coefficients which best match the input data, and subtracting the selected basis function from the input data. The coefficients of the basis functions used in the correlating step have values which effect pre-normalisation of the correlation results in each iteration of the process.
Patent GB-2351572-A (GB)
Title: Data processor with correlation matrix memory
Inventor: AUSTIN JAMES LEONARD
IPC: G06F17/30
Filed: 1999-06-26
Abstract: Input means 10 receives sets of input data to be stored in a correlation matrix memory 6. A sampler 2 derives, from each set of input data, a respective set of tuples, and a coder 4 codes each of the tuples, which are then combined for the respective set of input data. A separator generator 9 generates for each set of input data a respective, associated, unique separator, which is stored with its respective set of input data. Addressing means applies to the correlation matrix memory, for each set of input data, the respective combined coded tuples as a row address and the respective unique separator as a column address, or vice-versa. The system may receive sets of query data to be matched with the sets of input data, and may derive coded tuples for the query data analogues to those derived for the input data.

Title: Plasma etching endpoint controller
Inventor: HUGGETT PAUL GIDEON
IPC: H01J37/32
Filed: 1999-12-02
Abstract: An end point controller for an anisotropic plasma etching process comprising a series of alternating etching and polymerization steps, includes a monitor for monitoring the intensity of a characteristic process parameter, typically an optical emission, and producing a signal indicative of the intensity. A timer assembly determines the operation of the monitor during each etching step, the assembly comprising two sequential timers 100,105. The first timer 100 determines a time lag T1 (Fig 3) between the onset of the etching step and the operation of the second timer 105 which sets a time period T2 (Fig 3) within the etching step for monitoring the selected parameter. This enables the parameter to be monitored in the stable period T2 of each etching step. Other process parameters include the pressure of gas discharge, the plasma voltage and the electric current in the plasma.
