    摘要： An integrated torque and position sensor is set forth for measuring the relative rotational movement between an input and an output shaft and for measuring the final angle position of the output shaft. The integrated sensor includes a wheel that rotates with the shaft. An incremental sensing mechanism detects the incremental rotation of the shaft. In response to the shaft rotating to a predetermined angle, an actuation mechanism engages the wheel with a change gear for every new revolution in which the shaft passes. A segment sensing mechanism detects the segment in which the shaft is disposed. A method is set forth to calibrate and compensate the electrical outputs generated by the integrated torque and position sensor. The method produces common amplitudes and establishes a common angle with an expected phase angle shift for the electrical outputs. The compensated electrical outputs are inserted into a solver equation and the values generated by the solver equation are inserted into an algorithm to calculate the final angle position of the shaft.

    摘要： A collapsible steering column assembly preferably has a collapsible steering shaft that extends rotatably along a centerline and a collapsible column that houses and co-extends with the shaft. The column preferably has inner and outer jackets that retract axially to collapse the column. An energy absorbing device has a member engaged between the inner and outer jackets and controls the collapse of the column generally via a high load stage and a low load stage of operation. The member is preferably elongated axially having a distal end that is looped over and spaced radially outward from the remainder of the member. The distal end is attached disengagably to the outer jacket via a pin received in a hole in the distal end and a fuse engaged operably to the pin and attached to the outer jacket.
