Title: Method and apparatus for the optical detection of the roughness profile of a material surface
Inventor: WEBER KLAUS DR
IPC: G01B11/30
Filed: 1989-02-22
Abstract: A description is given of a method and a device for the indirect optical acquisition of the roughness profile of a material surface (10), in which method and device a light spot (14) is generated on the material surface (10) and the reflected light is fed to a light receiving arrangement (16). The reflection angle of the reflected light, and thus the respective surface inclination value, are determined for each scanned point of the material surface (10). The direction in which the light reflected in a scattered fashion is concentrated is formed in each case in order to determine the reflection angle. The desired roughness profile is subsequently reconstructed on the inclination values obtained.

Title: Hydraulic actuation systems
Inventor: HARRIES DAVID ANTHONY
IPC: F16H61/00

Granted: 2004-10-13
Abstract: An automatic transmission is operated by a hydraulic actuation system comprising an electric motor driven pump 223 delivering pressure, via non-return valve 276, to a main control valve 120, gear engagement control valves 144, 146, a clutch actuator 22 and to gear engagement actuators 114, 115. Main control valve 120 selectively connects the clutch actuator 22 to an accumulator 275 or to a reservoir 278 and also controls connection of the gear engagement actuators 114, 115 to the pump 223. A port 326 of recuperation valve 320 is connected to the reservoir 278 via gear engagement control valves 144, 146 so that spring (334, fig 10) urges piston (321) away from valve seat (328) opening inlet (330) and connecting displacement valve 300 and clutch actuator 22 to the reservoir 278 which delivers low pressure fluid to the actuator 22, thereby replenishing fluid, when actuator 22 is not under fluid pressure, required as a result of clutch wear. The gear engagement control valves 144, 146 selectively connect first and second working chambers 118, 119 of actuators 114, 115 to the main control valve 120 or to the reservoir 278. A pressure sensor 282 may be used, in a closed loop feedback control system, to control the pressure produced by the pump 223. Potentiometers 226, 227 may also be used in a closed loop control system to control valves 144, 146.

Filed: 2002-03-05
Granted: 2004-10-20
Abstract: A system and method for associating an MSISDN of a mobile terminal with a temporarily assigned IP address is disclosed. A first server located within a wireless communications network generates and transmits a start packet to a service network responsive to an access request by a mobile terminal. The start packet includes the MSISDN of the mobile terminal and an assigned IP address. A second server within the service network extracts the MSISDN in the IP address from the received start packet and stores this information together within a database. When a service request is made by the mobile terminal to a server in the service network, the MSISDN may be determined from the database and used to access user parameters in a user database.

Title: Improved method for estimating TDOA and FDOA in a wireless location system
Inventor: ANDERSON ROBERT J
IPC: G01S5/06
Filed: 2002-01-10
Granted: 2005-03-23
Abstract: A method, used in locating a mobile transmitter, includes providing a set of cross-correlation values, wherein each cross-correlation value is associated with a corresponding TDOA and/or FDOA estimate and is produced by cross-correlating a reference signal with a cooperating signal. The reference signal comprises a copy of a signal transmitted by the mobile transmitter as received at a first antenna and the cooperating signal comprises a copy of the same signal as received at a second antenna. The method further includes determining a most likely range of TDOA and/or FDOA estimates, and then identifying an optimal cross-correlation value within a subset of cross-correlation values corresponding to the most likely range of TDOA and/or FDOA estimates. The TDOA and/or FDOA value corresponding to the optimal cross-correlation value is then employed in calculating the location of the mobile transmitter.

Title: Method and apparatus for crop spraying
Inventor: BENEST ROGER SYDNEY
IPC: A01M/
Filed: 1992-07-23
Granted: 1995-11-08
Abstract: A dropleg row crop sprayer (12) senses boom height and tilt from ground-contacting droplegs (46) signalling through potentiometers (74, 76) to a boom control mechanism (84). The droplegs follow crop row wandering through a driven carriage (44). Dropleg attitude is assisted by a cam control system (94, 96). The boom (20, 21) floats through a spring suspension system (128, 138) and is damped by frictional abutment of the boom portions (20, 21), thereby permitting a single actuator (106) to control attitude. A lost motion linkage (126) protects the actuator (106) from snatch loads. Spray control is effected by use of microdroplets discharged from the droplegs (46) below the row crop leaf canopy which protects the droplets from wind turbulence, while electrostatic charges and droplet-energising air flow act to assit crop coating. Where conventional spray droplets are used, the spray direction is fore/aft of the row to minimize ground speed effects. <IMAGE>
