    摘要: An apparatus for and method of utilizing an Internet terminal coupled to the world wide web to access a legacy data base management system having a dialog-based request format using a standardized object-based command language, such as JavaScript, rather than the proprietary command language native to the legacy data base management system. This approach leverages the power of the legacy data base management without the need for the user to become familiar with the proprietary command language of the legacy data base management system. The approach is particularly efficient in that the user can provide parameters to the legacy data base management system as a parameter object.

    摘要: In an electric power assisted steering system, the output signal from a motor position sensor (9) comprising a number of Hall effect devices (A,B,C) or the like is combined with an index signal from a sensor (108) connected to the steering column shaft (1) or the rack (6) or a yaw sensor or other angular position dependent device to produce an accurate measure of steering angle relative to the straight ahead position. In a preferred arrangement, transitions in the Hall effect sensor output are used to drive a counter (106) which is reset whenever the index signal is produced to ensure it does not drift out over a period of time. Most conveniently, the index signal corresponds to the steering gear straight ahead position.

    摘要: An electrical power-assisted steering system is disclosed comprising a brushless electric motor (1) which has a plurality of phase windings connected at a start point and in which a switching means (13) such as a relay is provided in at least one phase of the motor, the switching means being movable between a closed position in which current is able to flow in the phase winding and an open position which prevents current flowing in the respective phase in the event of a fault. Also disclosed is a substantially rigid connector assembly (19) onto which is mounted the switching means (13), conductors (20) for connecting the motor phase windings and a motor position sensor (21) to an associated motor control means (6), the connector acting as a support for the motor stator, which simplifies the steps involved in assembly. In another aspect of the invention, the electrical power-assisted steering system includes a one-piece casing (3) which acts as a housing for the gearset, torque sensor, control means and at least part of the motor.

    摘要: A fluid flow control valve suitable for fitting to the fuel line (16, 18) of an internal combustion engine has a valve member (12) and a spring (14) urging the valve member (12) to a closed position where the valve member seals against a valve seat (13). A key-actuated setting mechanism (20, 21) allows the valve member (12) to be moved away from its closed position to an open position and a latch (31, 32) then holds the valve member in that open position. An electrically operated release (33) moves the latch (31) to free the valve member and permits the valve to close under the action of the spring (14). When fitted to a vehicle, energy may be provided to the release (33) automatically whenever the vehicle is left unattended so as to immobilise the vehicle.

    摘要: An optical displacement sensor is used to measure the rotary displacement between two shafts which rotate together. By connecting the shafts together by means of a torsion bar, the sensor may be used to measure transmitted torque. The sensor comprises first and second coaxial discs mounted on the shafts and having slots formed therein. A light source directs light through the slots onto an array of photodetectors and a data processor determines the displacement or torque from the positions on the array of images of the slot edges.
