Patent GB-2311864-A (GB)
Title: An NMR resistivity logging tool
Inventor: TAICHER GERSH ZVI
IPC: G01R33/563
Filed: 1997-03-26
Abstract: Formation resistivity is measured by detecting the phase or amplitude changes in received NMR signals due to propagation of the exciting and excited RF waves through conductive formations surrounding the borehole. The RF frequency or the static field may be altered to move the sensing volume 58 radially, so that phase changes can be ascribed to propagation in the material between the two positions of the sensing volume. RF power levels may be varied to obtain signals from selected radial depths. The tool may also measure porosity in the sensing volume.

Title: Redundant clock system prevents changeover glitches, eg for ATM cells
Inventor: LEE JUN-GYU
IPC: H04L12/56
Filed: 1997-05-21
Abstract: In a clock system having active and standby clocks 10, 20 for synchronizing cell data flow in a data system, and for preventing ATM cell data loss during active to standby clock switching, a prevent circuit 40 maintains the active clock cycle signal during the active/standby clock switching to ensure the proper setup time before the active clock is disabled. The prior standby clock will become active during the maintenance period, thereby providing the proper setup time before and after switching, permitting system redundancy without loss of data.
Patent GB-2314746-A (GB)
Title: Voice-coded data error processing
Inventor: HATTORI TAKESHI
IPC: G10L19/005
Filed: 1997-06-27
Abstract: A voice-coded data error processing apparatus includes a demodulator 1, an error frame detection section 2, an error data identification section 6, a partial conversion section 7, and a decoder 8. The demodulator 1 demodulates a received transmission frame containing voice-coded data which is encoded by ADPCM (Adaptive Differential Pulse Code Modulation) and modulated based on QPSK (Quadrature Phase Shift Keying). The error frame detection section 2 detects an error in the transmission frame from CRC (Cyclic Redundancy Check) information contained in the voice-coded data output from the demodulator. The error data identification section 6 identifies voice-coded data corresponding to an error portion when the error frame detection section detects an error frame. The partial conversion section 7 converts (e.g. for muting) only the voice-coded data corresponding to the error portion from the demodulator on the basis of an output b from the error data identification section. The decoder 8 decodes the voice-coded data output from the demodulator and the partial conversion section and outputs analog voice data.

Title: An automobile anti-theft lock that shields the steering wheel
Inventor: WU WEN-YIN
IPC: B60R25/022
Filed: 1997-10-21
Abstract: The anti-theft lock has a large semi-circular disc 1 and a small disc 2 that can come together to cover and lock a steering wheel. The small disc is pivotally rivetted to a plate 11 fixed to the large disc so that it may be swung to close with or open from the large disc. The outer circular edges of the discs are bent inwardly to form grooves 10, 20 that fit around the edge of a steering wheel (3, Figure 4). The large disc has a U shaped frame 13, with a push-in lock 14, for receiving a rod 21 that is attached to the small disc. When the rod is inserted into the frame a dead bolt of the push-in lock may be extended into one of a number of holes 22 provided in the rod to lock the discs together. As the anti-theft lock covers the steering wheel the wheel is prevented from being taken off its mounting and the safety air bag of the automobile is also protected.

Title: Varying phase between rotational shafts
Inventor: USHIDA MASAYASU
IPC: F01L1/344
Filed: 1996-06-13
Abstract: A housing 3 is connected to and rotatable with an input member 1 and a vane rotor 9 is connected to an output shaft 2 and accommodated in the housing 3 so as to be able to rotate within a predetermined angular range with respect to the housing. The vane rotor 9 and the housing 3 define hydraulic chambers (10, 11, 12 and 13, Fig 2) whose volumes are variable to determine the rotational position of vane rotor 9 with respect to the housing. A locking member 7 is accommodated in the rotor 9 (or in the housing 3) and is movable in a direction parallel to the rotational axis of the housing and rotor to engage in a bore 20 in a front plate 4 secured to the housing 3 (or in the rotor 9) when rotor and housing are at a predetermined angular position. The locking member 7 and bore 20 preferably have tapered surfaces, the locking member being moved to its locking position mechanically and retracted by hydraulic means. With this arrangement, it becomes possible to provide a control apparatus for varying the rotational or angular phase between the input and output shafts, e.g. crankshaft and camshaft of an internal combustion engine to control valve timing.

Title: Gear selection in the power train of a motor vehicle
Inventor: KUEPPER KLAUS
IPC: F16H59/02
Filed: 1999-02-15
Abstract: The positions of a gear selecting lever along two paths 101, 120 of a shift gate 100 are monitored by a first sensor (42, Figure 1) which transmits signals to a control circuit for an actuator of the gear shift mechanism. Path 101 is for controlling automatic shifting with standard positions R, N and D and path 120, attainable via position D, is for manual up/down shifting, M. Certain positions of the lever are also monitored and reported to the control circuit by one or more additional sensors S R  and S N  which influence the operation of the actuator in the event of failure of the first sensor. The ranges of lever movement 150, 151 detected by sensors S R  and S N  may overlap at 152 for improved sensitivity. Sensor S N  may also sense range 153 and a further sensor may sense range 154. Various types of sensor are disclosed.

Title: A method for determining the configuration of a plurality of nodes connected in a ring network
Inventor: SLADE ANTHONY JOHN
IPC: H04B10/275
Filed: 1999-03-12
Abstract: An optical ring network is disclosed comprising six nodes 1-6 interconnected by light guides carrying a number of optical carriers of different wavelengths. Eight traffic carriers and a separate supervisory carrier are provided. Each of the nodes input ports has a node identifier 1 to 6 associated with it which identifies the proceeding node at which a routing event occurred. For example, at node 1, all of the paths experienced a routing event, paths 6 and 7 having entered the network, and path 8 having been switched, hence all of the inputs to node 6 have a node identifier 1. At node 5, two of the inputs have a node identifier 1, as they were last routed by node 1 and have passed straight through node 6 whilst the third input has a node identifier 6, having originated at node 6. The node identifiers are carried in a frame format by the supervisory carrier which has a wavelength in the 1510nm range. Each node comprises input ports (fig.4, 20-22 ) which receive the data traffic and are connected to connection matrix ( 23 ). The supervisory channel is received at input port 24, and demodulator 25 extracts the incoming node identifiers from the supervisory carrier and passes them to an interrogation unit 26. A control unit 27 and generator 28 generate appropriate node identifiers which are added to the supervisory carrier by modulator 29 for transmssion to the neighbouring node.

Title: Improving image quality of a radar display
Inventor: FUJIKAWA TAKUMI
IPC: G01S7/06
Filed: 1999-06-01
Abstract: A device for improving the quality of the output display of a radar or like system comprises an image memory 1 for storing image pixel data relating to the output of a radar sub-scan which has been converted from polar to Cartesian coordinates 4, overlap detecting means 3 for determining whether a pixel of the preceding radar sub-scan coincides with a pixel of the latest sub-scan (i.e. when the radar has rotated by an angle which is less than the angle of divergence of the radar beam), and correlation means which rewrites the stored data relating to the preceding sub-scan with the data regarding the latest sub-scan if the pixel does not coincide 2. Preferably each point B on the latest sub-scan is compared to four other neighbouring points A, C, D-F (corresponding to the pixels of the previous scan) to see if an overlap has occurred. If a pixel overlap is detected the stored data may be replaced (6, Figure 2) by the data of the latest sub-scan if it is larger. The device may also account for pixel dropout by interpolation between the radar signals of the pixels of the first and second sub-scan (Figure 14).
