Patent number: 7373232Abstract: An electronically servo-assisted gearshift actuates a multiple gear-shifting that moves a chain from a current toothed wheel to a target toothed wheel not immediately adjacent to the current toothed wheel in a gearshift group having at least three toothed wheels. Actuating the multiple gear-shifting takes several steps (i) actuating a single gear-shifting to move the chain to a toothed wheel immediately adjacent to the current toothed wheel in the gear-shifting direction, and (ii) repeating step (i) until the immediately adjacent toothed wheel is the target toothed wheel.Type: GrantFiled: July 23, 2004Date of Patent: May 13, 2008Assignee: Campagnolo S.r.l.Inventor: Gianfranco Guderzo

Patent number: 7276899Abstract: A transducer comprising a fixed part and a mobile part which are mounted for relative motion about a given axis. On the shaft of the rotor part there is fitted a magnetized element consisting, for example, of an annular element diametrically magnetized at a single pair of poles. Mounted on the fixed part is a pair of Hall-effect sensors which are set angularly staggered by 90° about the axis of rotation of the shaft. The Hall-effect sensors generate corresponding output signals having values that vary in a continuous range. The values of the output signals generated by the transducer uniquely identify the relative positions of the aforesaid fixed and mobile parts with respect to the axis of rotation.Type: GrantFiled: March 7, 2006Date of Patent: October 2, 2007Assignee: Campagnolo Srl.Inventor: Gianfranco Guderzo
