Title: Bit-stream data compression
Inventor: XUGUANG LI
IPC: E21B47/12
Filed: 1996-11-07
Abstract: A plurality of sensors (30, 32, 34), each of which is coupled to a data channel, are mounted on a downhole logging tool (18) Fig.1,(not shown) or periodically measuring and sampling, at preselected timed sample intervals, petrophysical characteristics of the borehole sidewall material. The sample values So-Sn are arranged in a two-dimensional array of a plurality of time series in channel-sequential order, indexed by consecutive sample number. Means (28) are provided for transforming (52) the plurality of time series from the time domain to the wavelet domain. The wavelet coefficients for each transformed time series are compressed (56) by thresholding. The compressed wavelet coefficients corresponding to each time series are transmitted to a receiver (35) where the compressed wavelet coefficients are decompressed (70) by formatting same into a broken sequence of wavelet coefficients. The original time series is reconstructed by inversely transforming (36) the broken sequence of wavelet coefficients from the wavelet domain back to the time domain. Information about both the selected and rejected coefficients is transmitted.

Title: Diversity gain controlled cell-site transmission to minimise signal propagation to adjacent cells
Inventor: AZUMA TOMOHIRO
IPC: H04B7/24
Filed: 1997-07-16
Abstract: A cell-site base station apparatus comprises an array of diversity antennas 1-1.. 1-N for receiving multipath components of a mobile-transmitted signal. Receivers 5-1. .5-N, connected to the antennas, produce strength indication signals RSSI and demodulated signals. For transmission of a control signal from the cell-site to a mobile station, a variable gain transmitter TX is coupled to one of the antennas and the control signal is sent at a first power level. When a connection is established for the mobile station, the strength indication signals RSSI from the receivers are examined to detect a highest strength value and the antenna at which the multipath component of the highest value is arriving, is selected. The transmitter is then switched to the selected antenna for transmitting traffic signals and the gain of the transmitter is set to a second power level lower than the first power level to compensate for the transmit diversity gain of the selected antenna. The invention is particularly useful for time division multiple access-time division duplex (TDMA-TDD) mode of operation.

Title: Correction of web curl in packing apparatus
Inventor: CAHILL MICHAEL JOHN
IPC: B31B50/16
Filed: 1994-10-12
Abstract: Packaging material, particularly for forming blanks for hinged lid packets, is delivered to a packaging machine in web form and at least one creasing or shaping operation is performed on the web 2 prior to severing individual blanks 50 from the web 2. Individual blanks 50 are inspected for longitudinal curl, usually caused by the web 2 having been wound on a reel, and where necessary a correction is applied during feeding of the web, by adjusting the angle of wrap of the web 2 around a decurling roller 108. Folding or wrapping of a blank around an article to be packed in the machine is monitored and the creasing or shaping operation varied to optimise machine performance: for example, an adjustable creasing tool can be adjusted to compensate for tool wear.

Title: Alteration of data packet check data
Inventor: DRUMMOND-MURRAY JUSTIN ALEXAND
IPC: H04L1/00
Filed: 1998-06-05
Abstract: A node of a computer network receives an input data packet comprising communication data and check data. The communication data is altered, for instance by the insertion or removal of a VLAN tag, and new check data is calculated. An output data packet comprising the altered communication data and new check data is intentionally corrupted if the unaltered communication data is found to contain errors when checked with the check data. The chance of undetected corruption of the communication data within the node is minimised by providing memory means 20 from which the communication data is read in its unaltered or altered form and supplied to both the checking means 26 and new check data generating means 28 on the same bus 24.

Filed: 1998-06-24
Abstract: A polyimide dispenser 3, a moveable wafer stage 2, and a microscope 4 are used to form low dielectric constant polyimide layer patterns on ic dies. Comparing the results of timing tests conducted before and after forming the polyimide dielectric layer test pattern indicates whether the failure region is located below the test pattern region or outside the test pattern region. Performing the timing test repeatedly using successively polyimide test patterns allows the failure region to be determined to within an area of 30Ám<2>.
Patent GB-2327769-A (GB)
Title: Display system
Inventor: CROSSLAND WILLIAM ALDEN
IPC: G02F1/13357
Filed: 1997-04-25
Abstract: A modulator for modulating input collimated light, in particular UV, uses a spatial filtering arrangement to direct the input light onto phosphor emitters. To this end it comprises at least one switchable beam-deflecting device, such as a scattering LCD (1), at least one lens (3) and at least one secondary output means such as a phosphor screen (9, 11) which emits visible light when input light is directed towards it through the lens. The beam-deflecting device (1) is arranged so that, in its scattering state, it substantially prevents the input light from reaching the secondary output means, hence producing a dark output, while in its other (clear) state the UV light passes through the pinhole (5) and reaches the phosphor (11).

Title: Digital radio signal encryption/decryption
Inventor: PHILLIPS CHRISTOPHER FRANK
IPC: H04L25/03
Filed: 1999-04-20
Abstract: The invention encompasses a digital radio transmitter (2), a digital radio receiver (2) and a method of randomising data for digital radio transmission. A first digital signal (S1) contains voice and/or data. A second digital signal (S2) comprises different short pseudo-random data sequences, the second digital signal (S2) changing between different short pseudo-random data sequences at pre-defined time points. Both the order of the short pseudo-random data sequences and the timing of the pre-defined time points may vary in a pseudo-random manner. The first (S1) and second (S2) digital signals are combined to produce a third digital signal (S3) for transmission. Synchronisation data (320-332) is added to the signal, identifying the pseudo-random sequence currently in use. A digital radio receiver (2) is adapted to generate the second digital signal (S2), and to use this to extract the first digital signal (S1) from the received radio signal.
