The switching unit is capable of being coupled, so as to be able to communicate, to each of the first communication nodes and to each of the second communication nodes, and is configurable for transmitting a communication message between one of the first communication nodes and a second communication node, which may be unambiguously allocated to said first communication node. The switching unit may be coupled to the transmit-/receive aerial for wireless communication with each of the second communication nodes by way of the transmit-/receive aerial that may be shared for communicating with each of the second communication nodes.

Abstract: A mounting device for aircraft comprises an energy absorber and wherein the mounting device is mounted between a primary structure of the aircraft and the interior equipment. In this way the load acting on an interior equipment connected to the primary structure of the aircraft by way of the mounting device can be limited if a crash impulse occurs. The load acting on the primary structure is also limited, which can result in enhanced passive safety for the passengers and in weight reduction.

Abstract: The invention relates to a method for planning radio coverage and for predicting the high-frequency received power level of a mobile radio transmitter in buildings for a number of floors above and below the floor in which the transmitter is positioned with a transmitting antenna. The method can be used for the most frequently existing building types, i.e. reinforced concrete framework buildings and masonry buildings. The invention is advantageous in that a complex series of measurements for planning the radio coverage in buildings can be forgone. In addition, no complex calculations using semi-emperical models, e.g. ray tracing methods, are necessary. The inventive method offers rapid adequately precise results concerning the radio coverage to be expected in a building and, at the same time, for a large number of floors.

Abstract: Method for determining a state variable x from at least one sensor value by a cost function prepared for a measured value y for implementation in an arithmetic unit of a sensor system having at least one sensor and wherein the cost function depends on the respective state x to be measured and gives a deviation of an actual measured value from the calibration as a function of state x in order to determine the sought state x from this minimum. For the cost function, at least one approximation function is set up on the basis of at least one approximation region within the state region x, by which an approximation of the cost function is carried out with approximation functions with negligible error, wherein the sums of the approximation regions cover the entire relevant state region, and at least all local minima are determined on the basis of the approximation, in a selection of approximation regions, wherein optionally a global minimum is determined from the comparison of local minima.

Abstract: A timing element for a lubricant supply system is capable of using pneumatics for the time of delivery of lubricant for a preset duration. In one example, the timing element has a cavity having an entrance and an exit, a first piston and a second piston. The first piston and the second piston are disposed in the cavity. The first piston is coupled to the second piston in such that compressed air in the entrance of the cavity is capable of moving the second piston and closing the exit. A pneumatic timing element may be incorporated into a dosing unit that is capable of supplying an amount of lubricant in a mist to a plunger bushing of a machine tool without. The duration of the dosing may be controlled solely by pneumatics and may prevent excess pooling of lubricant in bore holes by shutting off lubricant delivery at a preset time.

Abstract: The inventive method enables existing contracts between a user and a telecommunications network operator to be enlarged by a user dialling into a customer subscription and administration server (CSAS). The access procedure of the existing contract relation is used for authenticating the user. The subscription of new contract components, such as clearing of a new terminal for instance that has been purchased by dispatch is carried out in a menu-controlled manner and by means of instruction texts and tactile inputs. The aim of the invention is to authenticate the calling user, authorise the additional contracts, changes and services which can be subscribed and administered by the corresponding user and store newly subscribed or changed contracts and services. The CSAS is connected to the corresponding data bases of the telecommunications network, such as CCBS, CDB and HLR. IP dialling options are optionally provided by means of the telecommunications network and/or the public internet.

Abstract: The invention relates to a method for personalization of GSM chips. At least one subscriber identification character (TMSI) and a card number (ICCID) are stored in the memory area of said chips in addition to a secret key (KI) and other optional data for personalization purposes. The invention aims to eliminate an unnecessarily high degree of complexity linked to management of all card data in an authentication centre (AC) and to preserve secret chip data in a more secure manner. According to the invention, final data is only written on the chip when the subscriber logs into a subscriber network. One advantage is that only initial data is written into the card enabling the customer to contact the computer centre of the information provider. During first contact the final data is traded between the card and the computer centre and written into the card. The computer centre is simply required to manage cards which have really been issued to customers.
