Abstract: A seating arrangement for a motor vehicle having at least one front vehicle seat and at least one rear vehicle seat in which the front vehicle seat has a backrest provided at a backrest frame as a unit which can be attached at least indirectly on the backside of the seat back and receives the headrest. A display screen or monitor can be mounted in that frame in a field or space specifically provided for that unit.

Abstract: A method for the dynamic control of the channel use of a transmission channel as well as a load generator for sending a test sequence generates the test sequence with several test patterns in accordance with a communication protocol to be used for transmission, preferably using a text editor and fixed definitions. A target channel use is defined. Then a predeterminable number of test patterns from the test sequence are sent and actual channel use is determined. Based on actual channel use a number of filler characters or a waiting time are determined for fixing the target channel use. Then the number of characters are sent or the waiting time is implemented until the next set of test patterns are sent. When all the test patterns of the test sequence have been sent, the transmission is terminated.

Abstract: Electrical knife having an elongate cutting device and an electric motor, the cutting device having a first blade and a second blade which is arranged parallel to said first blade, which blades are suitable for the electric motor to importing them a counter-rotating oscillating movement in the direction of their longitudinal axis, the cutting device also being equipped with a fixed guide tongue which at least partly extends along the blades and which is suitable for guiding the blades in the longitudinal direction.

Abstract: A system for monitoring a telecommunication link includes a computer which has a first processor, a first connection to a host storage medium and a first system bus interface, a measurement board which has a second processor, a second system bus interface and a first line interface for linking to a telecommunication link, and a system bus with which the first system bus interface and the second system bus interface are connected. The measurement board also has a measurement storage medium and an I/O interface linking the measurement board to the second storage medium. The measurement board with the measurement storage medium and the I/O interface form an embedded system. Data acquired from the telecommunication link via the line interfaces is stored directly in the measurement storage mediums rather than being passed in realtime over a system bus to the host storage medium.

Abstract: An arc extinguisher for low voltage switchgear, switching in air, includes a universally applicable variable attachment for adjustment of the arc extinguisher chamber to meet increased demands. The attachment is in the form of a chimney-like arc extinguisher chamber extension, for increasing the volume of the arc extinguisher chamber. It represents a moulded piece with a lower outline which exactly matches the outline of the arc extinguisher chamber cover, normally located on the arc extinguisher chamber and with an upper outline, identical to the upper outline of the switchgear housing for mounting the arc extinguisher chamber cover. Any number of attachments may be used in a stacked manner.
