Abstract: Distant support is provided to a personal hearing system user by a support provider over a network. Support provider and user communicate with each other by speech transmitted over the network. The user depends in regard to understanding speech on his or her hearing aids. During the support session the hearing aids may have to be removed, may have to be switched off or may be programmed in an unfavorable way. In this case, the user may not be able to understand the speech of the support provider any more. The system enables the support provider to select a message from a list of available messages which is then presented as a visual image to the user. The obstructed acoustical channel is bypassed by relying on visual communication.

Abstract: A turning tower arrangement for a printing press includes a turning tower (11) with turning bars (21, 22) arranged in a plurality of planes (E1-E12) one over the other for guiding printed webs one over the other. A first turning tower (11) and at least one second turning tower (12) are arranged directly one behind the other in the direction of a printed web entering one of the two turning towers (11, 12).

Abstract: An osteosynthetic fastening device, preferably in the form of a pedicle screw or a spinal column hook, has a channel in its upper section for receiving a support rod and a retaining element which clamps the rod in the socket through a spherical contact element.
