Inventor: JONES LLOYD G
IPC: E21B43/08
Filed: 2000-04-13
Abstract: A well screen having an internal alternate flowpath for delivering gravel slurry to different levels within a well annulus and a method for assembling same. The screen is comprised of an outer pipe (18) which is concentrically positioned over a base pipe (17) so that an annulus is formed therebetween. Both pipes are perforated along their respective lengths but only part way around their respective circumferences. The respective perforated sections radially align with each other when the pipes are assembled.

Title: An electromagnetic induction method and apparatus for the measurement of the electrical resistivity of geologic formations surrounding boreholes
Inventor: MORRISON HUNTLY F
IPC: G01V3/28
Filed: 2000-08-28
Abstract: Provided is a technique, including a method and a computer program product (19), to dynamically measure characteristics of geologic formations (10) while hydrocarbons (14a, 14b) are being extracted therefrom. Specifically, the present invention allows measuring the resistivity of geologic formations (10) in which a borehole (12a) has been formed therein and encased with a conductive casing, such as a conductive liner (16a, 16b). This has been achieved by providing a method and computer program product (19) that compensates for the effects of a conductive liner (16a, 16b) by measuring the characteristics of the geologic formation (10) as a function of a ratio of two magnetic fields sensed by a receiver (24) disposed in one of the boreholes (12a, 12b).

Title: Speech synthesis method and apparatus
Inventor: BRITTAN PAUL ST JOHN
IPC: G10L21/0208
Filed: 2002-05-13
Abstract: A speech synthesiser is provided with a style selection arrangement responsive to factors affecting intelligibility of speech output by the apparatus, to select a dialog style providing speech of at least a minimum level of intelligibility. The selected dialog style is used by a text generator when generating text form utterances. These text form utterances are converted into speech by a text to speech converter (6). The factor affecting intelligibility may be a measure of the intelligibility of the speech-form output, or an environmental factor such as background noise in the user's environment. The selection arrangement may be operative to balance intelligibility and naturalness of speech. The text to speech convertor may include a concatenative speech generator which produces an accumulated unit selection cost associated with a speech form utterance; the selection arrangement comprising a comparator for comparing the selection cost against a threshold in order to select a dialog style.

Title: Adaptive cruise control
Inventor: MIYAHARA SHUNJI
IPC: G08G1/16
Filed: 2003-06-04
Abstract: An equipped vehicle determines the range and relative angular position of a preceding vehicle, determines from these and the equipped vehicle's position the position of the preceding vehicle in a fixed co-ordinate system, and fits its path to a circular curve. The values of the circle's radius a and centre (x0,y0) are chosen to minimise the function e =   S  ((Xi-x0)<2>+(Yi-y0)<2>-a<2>)<2> i = n,n-1,n-2... ```Processing is simplified by converting to along- and cross-track co-ordinates relative to the equipped vehicle. The error e is then compared with a threshold: this indicates whether the preceding vehicle is in the same lane as the equipped vehicle or has changed lane, irrespective of whether the road is straight or curved.
