Abstract: A method of determining rotor speed of a wind turbine. The method involves receiving angular velocity sensor data indicative of an angular velocity of the wind turbine rotor hub, provided e.g., by a gyroscope and receiving acceleration sensor data indicative of an acceleration of the rotor hub in at least one radial direction relative to an axis of rotation of the rotor hub. The method further involves determining first and second estimated rotational speeds of the rotor hub based on the respective angular velocity sensor data and acceleration sensor data. The method also involves determining a correction value based on a difference between the first and second estimated rotational speeds, and applying the correction value to the first estimated rotational speed to determine the true current rotor speed of the wind turbine.

Abstract: A wireless communication method and protocol for wireless RF transmission of duplex audio in a flexible and self organizing network, especially audio data packets may be communicated according to a DECT protocol. Each wireless RF device is arranged to operate as a synchronization master or a synchronization slave, and where a negotiation algorithm is used to negotiate with other wireless RF devices present within wireless range to determine roles of master and slave(s). This allow wireless RF devices to leave or join groups of wireless RF devices within wireless range of each other, and still the synchronization master role is negotiated, and only one synchronization master is selected, whereas the remaining wireless RF devices will operate as synchronization slaves. Each wireless RF device performs a scanning of supported RF frequencies or channels to detect other wireless RF devices within wireless range.

Abstract: The invention refers to the manufacturing of ball-shaped metal products. The method consists in through heating of round billets made in appropriate size in a mid-frequency induction unit, rolling such billets into balls in a cross rolling mill at 950° C.-1070° C., cooling the balls down to 620° C.-700° C. in a cooling drum with forced air cooling, heating the surface of the balls up to 850° C.-930° C. in a high-frequency induction unit containing a rotating transport tube and multiple inductor sections, quenching the balls to 125° C.-160° C. in a quenching drum where they are cooled by running water, and allowing the balls to self-temper in the containers. The method enables better wear and impact resistance of metal balls when they are made of low-alloy steels, thereby allowing to reduce the carbon mass fraction of the used steel.
