The invention relates to the prevention of injuries and material damage caused by doors () of stopped and/or parked motor vehicles () by means of at least one camera () which monitors the exterior () of, especially the space next to and/or above, the vehicle (). According to the invention, a mode of operation monitoring the inner () and/or outer () door handle is activated and the exterior () of the motor vehicle () is monitored by means of the camera () if an evaluation unit () detects that a fixed or variable speed-related, acceleration-related, and/or distance-related threshold value (SW) is not met, e.g. when the vehicle () is stopped, or if said evaluation unit () detects that a signal unlocking the locking mechanism of the vehicle doors () is received while causing an acoustic, optical, and/or haptic warning signal to be issued as soon as a person actuates or unlocks optionally in an automated manner the vehicle door () handle () even though a stationary () or approaching () object has been detected in the field of vision () of the camera ().

The present invention supports total personal mobility in the Internet. For a subscriber, service readiness of a terminal that is not connected to the subscriber's home network is provided in that, with the aid of the identification of the subscriber which is inputted via the terminal, an IP address for the subscriber is interrogated at a server agent in the home network of the subscriber, and the interrogated IP address is transferred to a proxy node component of the terminal.

When merging optical pulse streams having a high bit rate, there is the problem that, for example given a bit rate of 40 Gbit/s, the pulses at the multiplexer output have 25 pulses temporal spacing and approximately 5 mm spatial spacing. Given a precision of 10% of the bit rate, the light waveguides must be matched with a precision of 0.5 mm, which previously required mechanical or inserted length-adjustable open beam optics and which leads to high outlay. In the optical delay line, by contrast, the temperature of a light waveguide is varied such that the desired optical length is set via the change in the refractive index of the optical fibers. The optical fibers are wound on coil bodies that have a through bore containing a heating element connected to a temperature control.
