The device has a electronic control unit receiving information (omegam, etaall, alphaemb, omega1, omega2, betapap) originating from the engine, the clutch and the gear box etc. for determining a code of control of the transmission of the vehicle using the clutch to automatically change the gear ratio as a function of motor speed. This control unit receives information of the amount of energy (Eemb...

Reflected imaging is used to perform non-invasive, in vivo analysis of a subject's vascular system. A raw reflected image (110) is normalized with respect to the background to form a corrected reflected image (120). An analysis image (130) is segmented fr

A product such as Emmenthal cheese or ham (10) is carried through a nuclear magnetic resonance unit (12) by a conveyor (11). The unit has permanent polarizing magnets (12), a winding (14) to add to the field and antennae (15,16) which transmit a radio frequency magnetic field towards the product (10) and capture the response signal. A controller (17) uses the response data to regulate the conveyor...

Machine comprises a body (1) with two parallel shafts (2,7) rotating and each carrying a serie of knifes (11,17). Knifes are working in pair as shears. The shafts are mounted on bearings (4,6,8,10) which can rotate around axis (13,14,15,16). Two jacks (9,20) are each mounted between a pair of bearing (4-6,8-10) and exert torque to compensate the shearing stress.;
