The present document relates to audio coding systems. In particular, the present document relates to efficient methods and systems for parametric multi-channel audio coding. An audio encoding system configured to generate a bitstream indicative of a downmix signal and spatial metadata for generating a multi-channel upmix signal from the downmix signal is described. The system comprises a downmix processing unit configured to generate the downmix signal from a multi-channel input signal; wherein the downmix signal comprises m channels and wherein the multi-channel input signal comprises n channels; n, m being integers with m<n. Furthermore, the system comprises a parameter processing unit configured to determine the spatial metadata from the multi-channel input signal. In addition, the system comprises a configuration unit configured to determine one or more control settings for the parameter processing unit based on one or more external settings; wherein the one or more external settings comprise a target data-rate for the bitstream and wherein the one or more control settings comprise a maximum data-rate for the spatial metadata.

A fastening system for medical devices includes a column-shaped interface profile () having a lens-shaped cross section with at least one convexly shaped, longer front surface () and with two shorter lateral surfaces (), which are parallel to one another and pass over into the longer front surface () via a tappet-shaped projection () each. A clamping device (), fits the longer front surface () of the interface profile () with the two tappet-shaped projections () in a positive-locking manner for fastening medical devices. The clamping device () has a concavely shaped outer surface and is provided with clamping jaws () that can be set on one side or on both sides for detachable fixation on the interface profile (). This construction offers the possibility of receiving medical devices and accessories on up to a maximum of four sides simultaneously, especially also via standardized rail elements ().

A display device () for use with a passenger conveyor () provides traffic flow direction information. One example includes a display panel () supported on a surface () that is conveniently positioned beneath the handrail () near a landing (). In a particular example, a handrail entry module () includes a handrail entry () and a support surface () that supports the display (). In one example, the surface () extends down and out from a vertical surface () associated with the handrail entry () to maximize visibility of the display.
