Abstract: A method for operating a permanently excited synchronous motor of a hand-held working device includes the steps of: sensorlessly determining a position variable representative of a position of a rotor of the synchronous motor at a standstill; determining a direction variable for a continuous rotation of the rotor from standstill in a direction on the basis of the determined position variable such that an absolute value of an attainable torque that can be generated by the synchronous motor during its sensorless actuation for the rotation in the direction is greater than an absolute value of a breakaway torque limit of the working device; and sensorlessly actuating the synchronous motor on the basis of the determined direction variable for the rotation in the direction.

Abstract: A sales support system for selling vehicles and/or vehicle accessories is disclosed. The sales support system has a computer-aided control system designed and equipped to receive customer-related customer information, and to determine and transmit customized customer-specific product information. The sales support system also has a showroom including at least one detection device and at least one output device. The detection device acquires at least one item of information about a customer who enters or is in the showroom, automatically and without any particular action by the customer, and passes the information to the control system. The control system determines at least one item of customized customer-specific product information from the acquired customer information, and passes the information to the output device. The output device outputs the information such that the customer can immediately perceive the product information that is intended for the customer.
