Abstract: A power converter arrangement includes semiconductor arrangements for two motors, wherein a control unit is used to continuously form a sum current composed of a first current and a second current and the sum current is compared with a predeterminable maximum value in order to protect the motors from being destroyed, where the control unit includes a device in which a priority grade is input by a user, where the priority grade describes the priority of one of the two machines, and where the control unit reduces the current of the respective machine that lacks priority according to the priority grade when the maximum value is exceeded.

Abstract: In order to produce a gasket that is adapted to be arranged between two components requiring sealing of which at least one contains a first metallic material which is less noble than aluminium and the gasket comprises at least one gasket layer including a plate consisting of a second metallic material which is nobler than the first metallic material, such that contact corrosion on the components requiring sealing is reduced or completely prevented, it is proposed that the gasket layer should comprise a sealing element which is arranged at an outer boundary region of the plate, should consist of an elastomer material and, in the installed state of the gasket, should gasket the gap between the gasket layer and the component which contains the first metallic material in a substantially fluid-tight manner.

Abstract: The invention concerns a biometric lock and a method for granting access to an object which is secured by such biometric lock. A terminal establishes a connection with an administration interface of the biometric lock via a communication network. An authorization procedure is executed in between the terminal and the biometric lock. If the authorization is positive, the biometric lock grants access to the administration interface. The terminal transfers biometric data of a new user, who shall be authorized to lock and/or unlock the biometric lock, to the biometric lock. It registers the new user and stores the received biometric data of the new user in a user registry. In the following, it compares actual received biometric data of a person requesting to access the object with the transfered biometric data. If the comparison is positive, the biometric lock is unlocked.

Abstract: A connection is set up between a sending and a selected network element of a digital synchronous telecommunications network without the help of a central management system. The telecommunications network is logically structured based on a hierarchy with at least two multiplex layers based on a protocol that is used in the telecommunications network with each network element being able to access at least a part of the multiplex layers. Using a broadcast that is being sent by the sending network element to all other network elements, possible paths with free transmission capacity are identified between the sending and the selected network element. To this end, first the most suitable multiplex layer for setting up the connection is selected. Then the broadcast is relayed via existing connections of the suitable multiplex layers, which the respective relaying network element can access. Then the connection is set up via one of the identified paths.

Abstract: It is proposed to use several distributed conference units (KE1, KE2) in a conference system (KS) for carrying out conferences, particularly broadband conferences, and to mix the signals (S1 . . . S4). The signals (S1 . . . S4) from subscriber stations (T1 . . . T4) involved in the conference are not necessarily mixed in a single conference unit, rather the mixing is distributed to several conference units (KE1 . . . KE2). In this way it is possible to mix signals that have a partially common transmission path in the communication system into a component signal (12) by means of a first conference unit (KE1). This mixed component signal (S12) is then transmitted to a second conference unit (KE2) and is mixed in this second conference unit (KE2) with one or more other signals (S3, S4). Since the mixed component signal (S12) during the transmission occupies the same bandwidth as a single signal (S1 . . . S4), the transmission capacity of the communication system (KS) needed for the conference can be kept small.

Abstract: A telecommunication device (11) for vehicle installation is proposed, which is equipped with an HF-transmitting and receiving device (22, 23), with different terminals and with a transmission network (19) between the HF-transmitting and receiving device and the terminals. The telecommunication-specific part of each terminal is physically separated from the actual user part (12, 13, 14) of the terminal, and installed in a central terminal control (15), which is connected with the HF-transmitting and receiving device (22). An efficient, optical transmission network (19) may be provided between the terminal control (15) and the user parts (12, 13, 14) of the terminals. Both the central terminal control (15) and the user parts (12, 13, 14) of the terminals are equipped with an interface unit for the transmission network (19). The telecommunication device (11) is less voluminous than a conventional device with individual terminals, and therefore more suitable for installation in the vehicle.

Abstract: A private branch exchange (PABX) with an integrated mobile part for controlling cordless terminals (HS) is established, which can be operated from base stations (BS).The private branch exchange (PABX) contains freely configurable interface modules (I/F) for wired (DE) and cordless (HS) terminals, which can be operated from a base station (BS). A central control unit (PABX-CPU) is provided to control all call handling and service feature control tasks, and a subordinate control unit (Mobile-CPU) for call setup and switch-off control of the cordless terminals (HS) in accordance with a set of assigned call numbers. The control units (PABX-CPU, Mobile-CPU) and the interface modules (I/F) are connected with each other through a bus system (BUS).

Abstract: An installation is described for establishing a connection between private branch exchanges (PABX), each of which has a base station allocated within a determined geographic area (GA), where the base station provides a determined number of utilization channels served by telecommunication, through which mobile cordless terminals communicate with the base station, and thereby with the branch exchange, throughout the geographic area. The base station (BS.sub.2) of a second branch exchange (PABX.sub.2) is located within the geographic area (GA) of a base station (BS.sub.1) of a first branch exchange (PABX.sub.1), and a wireless cross linkage is established by the two base stations (BS.sub.1, BS.sub.2) and their telecommunication (PABX.sub.1, PABX.sub.2).

Abstract: There are TDM communication systems in which synchronization is accomplished by means of code words which are transmitted at regular time intervals and coded in a particular code. In systems where the signals are transmitted in packets of uniform length, each of the code words contains the information of the so-called header of a packet. The checking device according to the invention successively checks all n-bit bit groups (X.sub.j to X.sub.j+n-) beginning with any one (X.sub.j) of the successive bits of the received bit sequence as to whether they are coded in a particular code. This is done by calculating the syndrome (S.sub.1 to S.sub.n-k) in several networks (N.sub.1 to N.sub.n-k) which operate in parallel and each of which calculates one syndrome component. The received bit sequence is delayed until the networks have calculated the syndromes for a given n-bit bit group and until a syndrome evaluation circuit (LS) indicates whether the bit group is a code word.
