Abstract: The invention relates to the emulation of a radio channel between moving transmitters and receivers with antennas. The relative position and relative movement and also the environment are used to ascertain propagation paths (P0, P1, . . . , PP?1) running between the antennas, for which propagation paths a damping factor (?p), a delay a delay (?p) and a Doppler frequency (vp) are separately ascertained. For each propagation path (P0, P1, . . . , PP?1), table lookup for the delay and the Doppler frequency is used to produce a respective path matrix (?p) that is weighted with the respective damping (?p) of the propagation path (P0, P1, . . . , PP?1), and all the path matrices are summed. The summed matrix (?) produced in this way is taken as a stating point for using a linear transformation to ascertain a transfer matrix (Y), the transformation reducing the dimension of the transfer matrix (Y) in comparison with the summed matrix (?) which corresponds to the coefficient vector (??p) of the delay.

Abstract: The present invention relates to a method of producing and loading silk particles, preferably spider silk particles, with a compound. In particular, the present invention provides a novel two step method for loading silk particles, preferably spider silk particles, with small and water-soluble compounds. Also disclosed are silk particles, preferably spider silk particles, loaded with at least one compound which are eminently suited as carriers for controlled and sustained delivery applications. Furthermore, the invention relates to pharmaceutical or cosmetic compositions comprising said silk particles, preferably spider silk particles, and a pharmaceutically active compound or cosmetic compound for controlled and sustained release. The present invention is also directed to silk particles, preferably spider silk particles, loaded with a compound obtainable by the method according to the invention.

Abstract: A power assist element for arrangement in a synchronizer hub of a transmission synchronization device includes a base body, which has a height, a longitudinal extension and a lateral extension, and which in the direction of the longitudinal extension comprises includes two opposite, distal end sections. In at least one end section a functional surface is formed, which in the installed state cooperates with the synchronizer hub. On the base body between the two distal end sections a central elevation is formed for engagement in a sliding sleeve groove on a bottom of a sliding sleeve. The central elevation includes at least one additional functional surface which can be brought into active connection with the sliding sleeve. The functional surface in the distal end section(s) is at an acute angle to the greatest longitudinal extension of the base body and oriented at an angle to the longitudinal extension.
