Abstract: Process for making solid methylglycine diacetate (MGDA) alkali metal salt (A), said process comprising the steps of (a) providing a 40 to 60% by weight aqueous solution of said salt (A) having a temperature in the range of from 50 to 90° C., (b) crystallizing salt (A), (c) removing said crystalline salt (A) from the mother liquor by filtration, and (d) subjecting the water containing filter cake from step (c) to an extrusion step.

Abstract: A secondary coil unit for a vehicle has a housing with a cover that can be removed from the housing. The secondary coil unit further has a secondary coil which is arranged in the housing and surrounds a core region. The cover and the housing are designed in such a way that an opening through the secondary coil unit is created when the cover is removed from the housing.

Abstract: A method is provided for producing an induction coil, in particular for a charging device for the cableless charging of an electrical energy storage device of an electrically driven motor vehicle. At least one coil wire is placed on a carrier fabric in a conductor loop-type coil pattern. The coil wire is stitched to the carrier fabric via at least one stitching wire.

Abstract: A coil unit inductively charges a vehicle. The coil unit has a housing and a coil. The coil is arranged at least partly in the housing. The coil has a plurality of windings of at least one electrical line, wherein the electrical line has two ends, and both ends of the electrical line are led out of the housing for connection to an electronic unit.

Abstract: The invention relates to a method for changing a group key GK for a secure data exchange in a group of network elements P1 . . . Pn (n=2, 3, . . . ) in a network system having a closed peer-to-peer configuration and a virtual synchronism supporting group communication protocol in a communication layer of a system architecture of the network system, wherein in the case of a change in a composition of the group of network elements P1 . . . Pn, caused by the join of a new network element Pn+1 into the group of network elements P1 . . . Pn or by the leave of a network element Pv (1?v?n) from the group of network elements P1 . . . Pn, a group key renewal, in which a network element Pi* (1?i?n) selected from the group of network elements P1 . . . Pn generates a new group key GKneu, is carried out and the new group key GKneu is transferred from the selected network element Pi to all the remaining network elements Pk (1?k?n, k?i) of the group of network elements P1 . . .

Abstract: A method for encrypting video data in which the encryption achieves a high standard of security and is carried out at a reduced computation cost. The encryption comprises disordering a set of video data to be encrypted and obscuring the disordered video data.
