Abstract: A method for remotely controlling the movement of a vehicle by means of a hand-held device is described. The method includes the following steps: activating a button by pressing and holding the button by a user; setting a tilt angle of the device by the user starting from an initial tilt angle when activating the button; receiving a signal representing the current tilt angle of the device; converting the received signal into a virtual pedal position, which corresponds to the position of a physical pedal corresponding to the virtual pedal; controlling the movement of the vehicle according to the virtual pedal position; and stopping the vehicle if pressing and holding the button is ended.

Abstract: A semi-rigid axle for a vehicle may include a torsion profile, which extends in a Y direction and is open downward in a Z direction; and two longitudinal control arms, which are connected to the semi-rigid axle and are each connected to the torsion profile by a gusset plate arrangement. Each gusset plate arrangement has a first gusset plate welded to one of the two longitudinal control arms and a second gusset plate arranged at least partially above the first gusset plate. First and second connecting sections of the first and second gusset plates are connected to one another and each of the first and second gusset plates is welded to an inside of the torsion profile on both sides in an X direction.

Abstract: A specimen holder (10) is proposed in order to create a capability for preparing, in a cutting device, in particular a microtome or ultramicrotome, a specimen that is to examined in an AFM. The specimen holder (10) is embodied in several parts. It comprises an insert (12) in which the specimen is secured. Also provided is a receiving ring (14) in which the insert (12) can be received. The insert together with the receiving ring (14) is mounted, in particular thread-joined, on a base element (16). As a result of the mounting of the receiving ring (14) on the base element (16), the insert together with the specimen is fixed in its position.

Abstract: A seat, particularly an air passenger seat, includes a seat part and a backrest. The backrest has a backrest element (10) with an arched, one-piece frame part (12) having at least one hollow profile (14). In order for the frame part (12) to have, at least in part, at least one additional hollow profile (16) and for the adjoining hollow profiles (14, 16) to be situated one behind the other in the normal direction of movement (flying direction (18)) of the seat, the backrest element is reinforced in the relevant areas in such a manner that, even in the event of a crash, the base frame structure remains intact.

Abstract: A method of making retrovirus vectors having selected characteristics, in particular an increased ability to infect a particular target cell, comprises subjecting a starting retrovirus or retroviral vector to a selection process in vitro which involves a plurality of rounds of infection of a host cell during which the retrovirus or retroviral vector evolves to attain the selected characteristics. Components of the evolved retrovirus or retroviral vector can be used in retroviral vector production systems for producing retroviral vectors having the selected characteristics. The invention is particularly useful for preparing retroviral vectors suitable for gene therapy.

Abstract: A process for improving the adherence of paint applied after thin-film anodization is characterized in that the anodized metal surfaces are brought into contact with an aqueous solution containing one or more of the following components: (a) 200 to 2000 ppm of a homopolymer or copolymer of acrylic acid, methacrylic acid, and/or their esters; (b) 200 to 3000 ppm of a poly(vinyl phenol) compound in which at part of the phenol rings carry an alkylamino substituent; (c) 200 to 3000 ppm of hexafluorotitanic acid, hexafluorozirconic acid, and/or their anions.
