Abstract: A rotating sensing device includes a base, a rotating element, at least one magnetic element set, at least one magnetic sensing element set, and a processing unit. The magnetic element set is arranged on the rotating element and includes an axial magnetic element and a radial magnetic element. The magnetic sensing element set is arranged on the base and includes an axial magnetic sensing element and a radial magnetic sensing element. When the rotating element is rotated relatively to the base, a magnetic variation relative to the axial magnetic element and a magnetic variation relative to the radial magnetic element are respectively sensed by the axial magnetic sensing element and the radial magnetic sensing element, so as to generate a sensing signal. The processing unit is adapted to obtain a rotation speed, a loading value, and a deflection value. In addition, a rotating sensing method is also provided.

Abstract: A clamping and positioning device includes a base, a rotary member, a moving assembly and an elastic member. The rotary member is rotatably disposed on the base and includes a stopping surface facing the base. The moving assembly includes a moving member movably disposed on the base to have a first and a second position. When being at the first position, the moving member is pressed against the rotary member to allow the stopping surface to apply a normal force to the base; when being at the second position, a gap is formed between the moving member and the rotary member so the normal force applied by the stopping surface of the rotary member is released from the base. The elastic member has two ends connected to the base and the moving member, respectively. The elastic member normally causes the moving member to be at the first position.
