Abstract: To convert energy, firstly a non-gaseous carrier medium is converted into a gaseous carrier medium by the introduction of thermal energy, so that the gaseous carrier medium rises and gains potential energy. Then the gaseous carrier medium is converted back at a specified height into a non-gaseous carrier medium. The potential energy of the recovered non-gaseous carrier medium can then be converted into another desired energy form.

Abstract: A system for varying a delay of an optical beam has a rotatable wheel and a set of one or more prisms mounted about a circumference of the rotatable wheel. The set of one or more prisms are positioned to retroreflect the optical beam that passes approximately tangent to the rotatable wheel to cause a delay or phase shift to the beam as the rotatable wheel rotates.

Abstract: A non-gaseous carrier medium is converted into a gaseous carrier medium by means of introduced heat energy, so that the gaseous carrier medium rises to a predefined height. The gaseous carrier medium is compressed. The compressed gaseous carrier medium is reconverted at the predefined height into a non-gaseous carrier medium by means of a cooling circuit receiving heat of the carrier medium. The heat received by the cooling circuit is then returned to be used for heating the carrier medium at any desired suitable location.

Abstract: The invention relates to a speed measuring device. The aim of the invention is to allow a precise and flexible speed measurement. The aim is achieved, whereby emission components are transmitted through two different paths and detected. A modification to the phase shift between the emission components in both paths, in relation to a non-operating device, represents a rate for the actual speed of the device, for evaluation means. The influence of a rotary motion on a modification to the phase shift is thus prevented or compensated. The invention also relates to a system, provided with such a device, and to a corresponding method of speed measurement.

For assistance a, related to a landing and/or a takeoff area 10, stationary-generated fluid current is provided in order to introduce energy into the flying object. The invention likewise relates to an apparatus, which has a fluid current generator 11 for generating the fluid current.

Abstract: A device for converting low currents, applied by a non-ideal current source to an input of the device, into voltage signals comprises a converter for converting the low currents into voltage signals, at least one feedback branch, and a coupler. The output of the converter is fed back to an input of the converter by the feedback branches and the coupler. The coupler is wired so that control currents supplied by the feedback branches are applied to the input of the converter via the coupler to control the low currents applied by the non-ideal current source at the input of the device. The control currents are applied to the input of the converter via the coupler with a reduction of capacitive, inductive, and ohmic influence of the feedback branches and with an amplitude matching of the control currents.

The fiberglass ring forms at least two propagation paths wherein the oscillations from the laser rotate in opposite directions. The decoupler decouples the oscillations which are superposed at the measuring location where an evaluation signal is detected.
