Abstract: A deformation element for absorbing lateral impact forces in the lateral region of a motor vehicle has at least two hollow chambers disposed one behind another in the direction of action of the lateral impact forces. An axial extension of which is in each case oriented at right angles to the direction of action of the lateral impact forces. The deformation element has at least one fastening portion for mounting the deformation element on an associated lateral sill portion of the vehicle.

Abstract: An apparatus and a method is provided for scheduling information transfers between a wireless network and a fixed network. According to the invention information transfer between accessible local elements linked to a wireless network and a fixed network is scheduled by directing an information request from the local elements to an operating unit interfacing the wireless network and the fixed network, storing the request in the operating unit and processing the request depending on the congestion in the wireless network. Thereby the processing of the request comprises operating of the request and subsequently returning the information according to the request obtained from the fixed network to the local element within the wireless network depending on the congestion of the latter. Thereby the transfers in both directions are fully managed by the operating unit.

Abstract: In modem, modularly structured mobile radio systems, a call between a base station and a mobile subscriber station is to be handed over to a different base station the moment the mobile subscriber station leaves the coverage area of a base station. For this purpose, a switching system providing the route between a fixed network and the base stations is to carry out appropriate switching operations. In order to realise shortest possible dead times caused by interruptions during call handovers from one radio cell to another radio cell, a first and a further base station each comprise switching equipment for inserting a signal (S.sub.k) coming from a switching center into a signal (S.sub.g) going to the switching center.

Abstract: Cellular mobile radio systems provide full-duplex communication between base stations and mobile stations and with the fixed public service network. Also known are trunked mobile radio systems wherein a group of mobile users can exchange information with each other in the half-duplex mode over a common channel, only one user transmitting to the others at any time. It has been proposed to provide mobile radio sets which are especially adapted to be switched for use in either of such systems. The present invention avoids the need for specific adaptation of a mobile radio set for that purpose. Instead, it enables a cellular mobile radio system to be selectively converted into a trunked mobile radio system by providing for the base station to couple an up-link radio channel of any mobile user to down-link radio channels of a selected group of mobile users. One or more such user groups can be formed, only one radio channel being used for each group.
