Filed: 1997-11-12
Granted: 2002-01-01
Abstract: A yaw moment control system is provided to eliminate an under-steering tendency generated due to the insufficiency of a cornering force of from driven wheels of a vehicle. More specifically, in place of a longitudinal acceleration Xg and a lateral acceleration Yg used for calculating the amount of torque distributed, a corrected longitudinal acceleration Xg' larger than the value directly proportional to the longitudinal acceleration Xg and a corrected lateral acceleration Yg' larger than the value directly proportional to the lateral acceleration Yg are used, thereby increasing the amount of torque distributed to between inner and outer wheels during turning of the vehicle. A yaw moment is generated which is directed inwards in the turning direction to prevent the under-steering tendency which is generated due to the insufficiency of the cornering force of the front wheels.

Abstract: Particle detecting apparatus for detecting oil mist or other particulate matter comprises a measuring section (5) and an input/output section (6) which are removably attached together. A measuring chamber (60) receives gaseous fluid by diffusion from a receiving chamber (30) connected via an inlet (16) to an area being monitored. The measuring chamber (60) is defined by a cylindrical body (34) housing pairs of light emitting diodes (46A, 46B...) positioned diametrically opposite each other and directing light towards each other through a sampling volume (62) which is viewed by a photo-diode (52) through a viewing aperture (56). The photo-diode (52) detects light scattered by particles in the sampling volume (62). A glass tube (64) protects the LEDs (46A, 46B) from contamination and can easily be cleaned or removed and replaced. Each of the LEDs (e.g. 46A) can temporarily be de-energised in turn so as to act as a light detector, its output in response to light received from the opposite LED (e.g. 46B) being thus a measure of any contamination.  The measuring and input/output sections (5, 6) can easily be separated for servicing or replacement.

Abstract: A waveguide (10) having alternating regions (18, 12) of different crystallographic orientations, thereby providing quasi-phase-matching for a non-linear frequency conversion, in which two wafers with epitaxial layers thereon are bonded together having different, preferably opposed, crystallographic orientations. One wafer is etched away, and a grating is etched such that one part of the grating has the orientation of one wafer an d the other part has the orientation of the other wafer. Thereafter, a wavegui de structure is epitaxially deposited upon the differentially oriented template  so that the waveguide is differentially oriented in its axial direction. Thereby, quasi-phase-matching non-linear effects can be achieved.
