Abstract: An active noise reduction system is disclosed which includes an earphone to be acoustically coupled to a listener's ear when exposed to noise. The earphone comprises a cup-like housing with an aperture; a transmitting transducer which converts electrical signals into acoustical signals to be radiated to the listener's ear and which is arranged at the aperture of the cup-like housing, thereby defining an earphone cavity located behind the transmitting transducer; a receiving transducer which converts acoustical signals into electrical signals and which is arranged behind, alongside or in front of the transmitting transducer; a sound-guiding tube-like duct having two ends; one end is acoustically coupled to the receiving transducer and the other is located behind, alongside or in front of the transmitting transducer; a first acoustical path which extends from the transmitting transducer to the ear and which has a first transfer characteristic; a second acoustical path which extends from the transmitting transducer through the tube-like member to the receiving transducer and which has a second transfer characteristic; and a control unit which is electrically connected to the receiving transducer and the transmitting transducer and which compensates for the ambient noise by generating a noise reducing electrical signal supplied to the transmitting transducer. The noise reducing electrical signal is derived from the receiving-transducer signal, filtered with a third transfer characteristic, and in which the second and third transfer characteristics together model the first transfer characteristic.

Abstract: A method is provided for deploying a policy from a 3GPP core network to a non-3GPP access network. The policy relates to a connection established from a mobile terminal to the 3GPP core network via the non-3GPP access network. A local IP address is received (S1) at the 3GPP core network, the local IP address having been acquired by the mobile terminal during establishment of the connection. At the 3GPP core network, establishment of a policy control session is initiated (S3) from the 3GPP core network to the non-3GPP access network. The received local IP address is used to determine (S2a) or to enable determination of (S2b) the non-3GPP access network used for the connection with reference to shared I P addressing information. The shared IP addressing information sets out different respective ranges of local IP addresses assigned to a plurality of such non-3GPP access networks. At the 3GPP core network, the policy is provided (S4) to the non-3GPP access network using the policy control session established as a result of the policy control session initiation step. The policy is for deployment in the non-3GPP access network in relation to the established connection. A method is also provided for use at the non-3GPP access network.

Abstract: The invention relates to a method for controlling a converter (4) of a wind turbine, the converter being connected to a rotor (32) of a doubly fed asynchronous generator (3) in order to feed electrical energy into an electric network (9), wherein the converter (4) comprises a network-side inverter (41), a generator-side inverter (42), and a controller (5), which outputs target values for demanded reactive power to at least one of the inverters (41, 42). According to the invention, a reactive power target signal is determined for the portion that the network-side inverter (41) contributes to the demanded reactive power QT, a slip signal (s) is determined from the frequency of the network (9) and the rotational speed of the generator (3), a gain value is calculated according to the slip signal, and the gain value is modified according to the reactive power target signal for the network-side inverter. The distribution of the reactive power between the two inverters is thus optimized over a wide operating range, not only at individual predetermined operating points as in the prior art. The invention further relates to a wind turbine having a correspondingly designed converter controller.

Abstract: An optical device under test (DUT) is interferometrically measured. The DUT can include one or more of an optical fiber, an optical component, or an optical system. First interference pattern data for the DUT is obtained for a first path to the DUT, and second interference pattern data for the DUT is obtained for a second somewhat longer path to the DUT. Because of that longer length, the second interference pattern data is delayed in time from the first interference pattern data. A time varying component of the DUT interference pattern data is then identified from the first and second interference pattern data. The identified time varying component is used to modify the first or the second interference pattern data to compensate for the time-varying phase caused by vibrations, etc. One or more optical characteristics of the DUT may then be determined based on the modified interference pattern data.
