Abstract: Systems and methods for automatically deploying warning devices for an autonomous vehicle. A method includes automatically stopping the autonomous vehicle when there is an emergency and automatically deploying one or more warning devices from one or more warning device deployment mechanisms attached to the autonomous vehicle while the autonomous vehicle is stopping such that the warning devices drop from the warning device deployment mechanisms. A system includes one or more warning device deployment mechanisms attached to the autonomous vehicle and one or more warning devices stored in the one or more warning device deployment mechanisms. The system includes one or more controllers configured to automatically stop the autonomous vehicle when there is an emergency, and automatically deploy the warning devices from the warning device deployment mechanisms while the autonomous vehicle is stopping such that the warning devices drop from the warning device deployment mechanisms.

Abstract: A warning device for a warning device deployment system for an autonomous vehicle. The warning device includes a tetrahedron frame having four triangular faces and at least one reflective material on the tetrahedron frame. The tetrahedron frame defines an expanded shape of the warning device. The warning device is self-expandable such that the warning device is compactable to a reduced volume when the warning device is stored in the warning device deployment system and expandable to the expanded shape when the warning device is deployed from the warning device deployment system. A warning device deployment system includes one or more warning device deployment mechanisms attached to the autonomous vehicle and the one or more warning devices stored in the one or more warning device deployment mechanisms. The one or more warning devices are deployed from the one or more warning device deployment mechanisms.

Abstract: A port multiplier for extending ports of a radio communication test instrument comprises an input for receiving at least one input signal, a power supply unit, a control logic, and at least one output for outputting a processed signal. The port multiplier is configured to split the at least one input signal into its different components such that a radio signal component of the input signal is forwarded to the at least one output. A power signal component of the input signal is forwarded to the power supply unit. Further, a control signal component of the input signal is forwarded to the control logic. Moreover, a radio communication test system for testing a device under test is described.

Abstract: The present invention provides a frontend module for a modular configuration of a frontend. Each of the frontend modules is configured to achieve a configuration for combining multiple frontends. In particular, multiple signals relating to a relative small frequency range may be combined together to achieve a broadband test signal. For this purpose, radio frequency interfaces are provided in the frontend module for exchanging/distributing radio-frequency signals between the individual frontend modules.

Abstract: The invention relates to an electronic assembly comprising a plurality of electronic component groups and a cooling device for cooling the electronic component groups. The cooling device provides a cooling-power distributor. A cooling power of the cooling device can be individually controlled by the cooling-power distributor for every component group. Furthermore, the assembly provides temperature-registering means for every component group for registering a temperature of every component group, and a load-determining device for determining a parameter for every component group which describes the load experienced by a component group on the basis of the temperature registered for this component group. A control unit controls the cooling-power distributor on the basis of the parameters determined for the component groups.

Abstract: A method for monitoring system variables of an energy distribution or transmission grid includes measuring at least one of the system variables of a system variable vector, estimating the system variables using system equations reflecting a dynamic and static behavior of the system variables on the grid, and displaying the estimated system variables on a screen. To improve the accuracy of the estimated system variables, maximum log-likelihood estimates of the system variables are determined based on minimizing an objective function which includes a probability density function of the corresponding measurement error for each of the system variables for which measurements are taken. The objective function also includes system equations having as the system variable vector at least all of the system variables for which measurements are taken, and for at least one parameter of the state equations a corresponding predefined range of parameter values expressed as a parameter uncertainty.

Abstract: A circuit for signal conditioning including a first stage with a digital/analog converter, a second stage with an I/Q-modulator, and at least one third stage with a mixer. Instead of a multiplicity of independent oscillators, a shared oscillator is provided for the first, second, and third stages, from an output signal of which a respective oscillator signal and clock-pulse signal for each stage of the first, second, and third stages is derived. The oscillator signal and respective clock-pulse signal of the oscillator are supplied via a frequency divider to at least one stage of the first, second, and third stages, or the oscillator signal of the oscillator is supplied via a frequency multiplier to at least one stage. Also, the oscillator signal of the oscillator is supplied as a reference signal to a frequency synthesizer of at least one stage of the first, second, and third stages.

Abstract: The invention relates to an apparatus for fixing a ligament, which comprises a bone-anchoring element having a proximal end and a distal end which has a bore running in the longitudinal direction, and which comprises a clamping sleeve having a proximal end and a distal end, which clamping sleeve can be accommodated in the bore. The clamping sleeve is radially expandable, with the result that the ligament can be fixed between the clamping sleeve and the bore of the bone-anchoring element.
