摘要： An actuator system may include a first actuator for being operated by a user, a second actuator for performing a movement of the user, and a transmission channel between the first actuator and the second actuator for transmitting the velocity and the force of the first actuator to the second actuator and vice versa. The actuator system may also include a controller, wherein the controller is configured such that, with the aid of the controller, the energy of the first actuator is adapted to be measured as a desired energy, wherein the transmission channel is configured for transmitting the desired energy to the second actuator and the controller is configured for controlling the damping of the second actuator as a function of the desired energy.

摘要： A 3D input device, in particular a mobile 3D input device, has a housing and an input element arranged within the housing. The input element has at least a first side and a second side opposite the first side. The 3D input device has a sensor device. The input element is movable relative to the housing in six components. The sensor device detects the movements and/or the positions of the input element relative to the housing. The first side of the input element or the second side of the input element or the first side and the second side of the input element are together configured in such a way that a user can complete a movement of the input element along the six components via an action on the input element. A mobile device and a 3D remote-control each have at least one such 3D input device.

摘要： In order to suppress aeroelastic instabilities on a transonically operating aircraft comprising a pair of wing halves at which a transonic flow forms spatially limited supersonic flow regions that each, in a main flow direction of the flow, end in a compression shock, a boundary layer of the flow is temporarily thickened-up in at least one supersonic flow region at at least one of the two wing halves, when approaching a flight envelope of the aircraft with increasing flight Mach number of the aircraft. The boundary layer of the flow is thickened-up to such an extent that the compression shock at the end of the respective supersonic flow region at the present flight Mach number of the aircraft induces a separation of the boundary layer of the flow from the wing half.

摘要： Method and system of calibrating a sensor system which comprises sensor A and sensor B. Sensor A has a transmitter TXA for emitting a signal STXA and a receiver RXA for receiving a signal SRXA, wherein RXA and TXA operate independently in a radar mode of sensor A. Sensor B has a transmitter TXB, a receiver RXB, and a unit D, which is used to connect TXB to RXB in a transponder mode of sensor B, with the result that a signal SRXB received by RXB is emitted again by TXB as a signal STXB. A gain Gcon,B between signal SRXB and signal STXB is predefined. In a radar mode of sensor B, TXB is not connected to RXB, with the result that TXB and RXB operate independently. Emitted signals may be radar, light, or acoustic signals. The method and system can calibrate radar systems, lidar systems, or sonar systems.

摘要： An apparatus for unfolding a rolled-up, elongate hollow body provides for stabilizing the unfolding body in a transition region. The hollow body has a closed cross-sectional profile. The unfolding mechanism has a winding core on which the hollow body is rolled up and compressed in a first state, and, by rotation, transfers the hollow body to an unrolled and unfolded second state. The hollow body is guidable between an outer fixing element positioned outside the hollow body and an inner supporting element which lies against an inner wall of the hollow body. The inner supporting element and outer fixing element interact in a form-fitting and/or force-fitting manner for axial positional fixing of the inner supporting element without a directed mechanical connection.
