    Abstract: A motor control apparatus includes a current estimation unit configured to output a detected current value corresponding to each of the three-phase AC currents based on the measured current value and rotor rotation angle information of the motor. The current estimation unit defines a phase whose duty ratio of a driving pulse supplied to an inverter circuit, which generates the three-phase AC currents, becomes more than or equal to an operation switching threshold as an estimation target phase, calculates, for the estimation target phase, an estimated current value based on a coefficient value, which is calculated from the measured current value by the current measurement unit in a period in which the duty ratio of the driving pulse is lower than the operation switching threshold, and the rotor rotation angle information, and outputs the calculated estimated current value as the detected current value of the estimation target phase.

    Abstract: An interactive processing device according to an embodiment acquires one/more items' information for predetermined operation through interaction with a user, and includes one/more itemized-processing-units and an interaction-control-unit. The itemized-processing-units corresponds to the items. The interaction-control-unit controls the interaction collaboratively with the itemized-processing-units. The interaction-control-unit transmits user-input information to each itemized-processing-unit. Each itemized-processing-unit extracts a candidate for to-be-acquired information and transmits the candidate to the interaction-control-unit with likelihood information of being the to-be-acquired information. The interaction-control-unit determines a candidate having first-threshold-satisfying likelihood as information of an item corresponding to the candidate-transmitted itemized-processing-unit. When undetermined information item exists, the interaction-control-unit outputs inquiry for the item information.
