An information acquisition system includes a transmission device configured to transport a carrier carrying a number of products, an information acquisition device configured to obtain identification information of a corresponding one of the plurality of products when the carrier stops moving, a control device, and a positioning device. The positioning device includes a positioning member, a number of elastic members, a number of blocking members spaced apart and mounted on the positioning member, and a driving member fixedly coupled to the positioning member and configured to drive the positioning member to move telescopically between an extended position and a retracted position. When the positioning member is in the extended position, one of the blocking members blocks the carrier from moving. When the positioning member is in the retracted position, the blocking member that was blocking the carrier unblocks the carrier to allow the carrier to move.

An assembly consisting of a control member which comprises a carrier, an operating part movably supported on the carrier, an electromagnetic actuator comprising an armature and a coil for driving the operating part movingly relative to the carrier is provided. The assembly further comprises an electronic control system connected in an electrically conductive manner with the electromagnetic actuator for applying a control voltage to the electromagnetic actuator for a predetermined control period in a control step in order to generate a haptic feedback; a measuring circuit connected in an electrically conductive manner to the electromagnetic actuator for measuring a current present at the electromagnetic actor and for generating a measuring signal proportional thereto; and an evaluation unit connected in an electrically conductive manner at least to the measuring circuit and designed, in a measuring step offset in time relative to the control step, to apply a measuring voltage to the electromagnetic actuator by the electronic control system for a predetermined test period shorter than the control period, in order to measure by the measuring circuit the current which arises at the electromagnetic actuator as the test period elapses due to the application of the measuring voltage and to generate a measuring signal proportional thereto, and in order to obtain a characteristic value of the actuator based on the measuring signal.
