4 results about "Coupling ratio" patented technology

Systems and methods for generating spectrally compressed photons from broadband emitted photon pulses. The system can include an input coupling having a first coupling ratio and an output coupling having a second coupling ratio. The first coupling ratio is configurable and the second coupling ratio is fixed. A cavity can be connected to the input coupling and the output coupling. A controller in electrical communication with the coupling device can be configured to change the first coupling ratio of the input coupling.

Disclosed is an electrical power system having a transmission system with a first voltage, a distribution network with a second voltage, and a coupling unit having a coupling ratio, and a distributed generation unit DGU to generate the electric power and be in a communication with the distribution network. The system may also have a control unit to control the coupling unit and the DGU in an emergency operating mode to bring and / or to keep the value of the first voltage between a first threshold and a third threshold, and / or the value of the second voltage between a second threshold and a fourth threshold, the first threshold corresponding to the value of the first voltage at the time of entry into the emergency operating mode and the second threshold corresponding to the value of the second voltage at the time of entry into the emergency operating mode.

Optical system (1), comprising at least the following components: a light source (2), a first optical device (3) for the directed emission of light from the light source (2) via a transmitting light path (100) and for the directed reception of emitted light via a first receiving light path (101), a second optical device (4) for receiving emitted light in a directed manner via a second receiving light path (101'), wherein either the first or the second optical device (3, 4) is operable for receiving emitted light, a detector (5, 5a, 5b) for detecting the received light and a coupling device (10) for splitting the emitted light between the two optical devices (3, 4) according to a predefinable coupling ratio and for forwarding received light from one of the two optical devices (3, 4) to the detector (5, 5a, 5b).
