Abstract: A method and apparatus wherein, for a network protocol a message is encoded in a first computer unit upon employment of the encoding format of the network protocol, being encoded to form an encoded message. The encoded message is subjected to a cryptographic process. The cryptographically processed message thereby formed is again encoded upon employment of the encoding format of the network protocol. The cryptographically processed message encoded in this way is transmitted from the first computer unit to the second computer unit. In the second computer unit, the received message is decoded according to the encoding format of the network protocol, and an inverse cryptographic process is applied to the decoded message. The inversely cryptographically processed message is again decoded according to the encoding format of the network protocol.

Abstract: A speech recognition system and method are provided for the speech-controlled inputting of short messages into a telecommunications terminal, in particular a mobile phone or cordless phone, having a speech recognizer module which operates independently of the speaker, a text/phoneme converter module and/or an auxiliary speech recognition module which operates in a speaker-dependent fashion and has the purpose of converting the text inputs or text transfers into a phonetic script which is adapted to the speech recognition module, and a vocabulary control module for supplementing the vocabulary or for replacing elements of the vocabulary by words or phrases which have been input or transferred.

Abstract: After a key pair with a public key and a corresponding private key has been determined on the basis of an initial value, the initial value is made available to a user. The private key can then be erased. When the user wishes to carry out a cryptographic operation based on the “Public-Key-Technology”, the user enters the initial value into a computer and, upon utilization of the initial value, a regenerated private key is formed, which corresponds to the private key that had been previously formed but was then erased.

Abstract: A system for selectively picking up a speech signal focuses on a speaker within a group of speakers who wishes to communicate something to the system using an image analysis algorithm to identify, based on a recognition feature, a position of at least one person who wishes to give the system voice commands. The detected position is then used to adapt a directional microphone to the at least one person.

Abstract: An initial voice input is associated with a recognition input in the framework of voice recognition and the recording of the voice input is stored in a memory in association with the recognition input in such a way that the voice input is emitted in the form of an audio response during further acknowledgement processes.

Abstract: A conveyor system for transported goods which are transported with a preset transport speed and method for operating the conveyor system are described. The individual conveyers of the system are driven by asynchronous motors. Sensors associated with the conveyors measure the actual transport speed of the transported goods on conveyors to determine the dependence of the actual transport speed on the load, such as the weight of the transported goods. A controller adjusts the speed of the conveyors based on the signals received from the sensors.

Abstract: A transport system, in particular an airport luggage transport system and a controller for the transport system are described. The transport system transports items to a predetermined destination on predefined transport routes via several branching locations. A master controller sets for each transported item a destination and a transport route, which are processed by one or more slave controllers. Each transported item is given an identification number that is identified by the slave controller. The master controller provides to the slave controller the destination associated with each identification number and associates with each destination at the branching locations a forwarding direction. Forwarding is processed by the slave controller without an interrogation of the master controller, based on the preset association at the branching locations.

Abstract: An apparatus for fastening and wiring of a plurality of electrical units, particularly in a switchgear cabinet. At least one mounting crosspiece (12-15) accommodating the electrical units on its mounting side can be fastened to at least two bearing rails (10, 11) arranged vertically and behind them, fasteners for fastening the electrical units on the mounting crosspiece (12-15) being provided. This mounting crosspiece (12-15) shaped like a flat strip has, on its rear side opposite the mounting side (29), an integrally formed holding rib (28) extending over its length and having a mounting groove (30) open toward the mounting side (30) designed for accommodating the heads (33) of mounting screws (34) for fastening the mounting crosspiece (12-15) by means of the holding rib (28) on the bearing rails (10, 11). At least one of the two opposite longitudinal edges of the mounting crosspiece (12-15) shaped like a flat strip can be provided with a wiring comb (39).

Abstract: A profile strip of insulating material is proposed for holding many electrical cables (27)-(30) in switching and control boards and panels, which consists of a mounting section (13) for fastening on a mounting track and a comb-like cable holding section (15) formed thereon. This cable holding section (15) consists of many parallel teeth (14), between which insertion slits (26) for insertion or installation of electrical cables are formed. The insertion slits (26) are limited at the sides by elastic tabs (21) formed on the teeth (14). Between every two teeth (14) a shorter intermediate tooth (20) is positioned such that it divides a portion of the insertion slit (26) into two narrower partial slits. This permits the elastic tabs (21) to hold, in variable fashion, not only cables of smaller diameter (29) in the portion with the intermediate tooth, but also cables of larger diameter (27), (28) in the remaining portion.

One of the platforms is stationarily fixed on the traverses and the other one of the platforms is movably supported on the traverses for displacement in direction of the stationary platform. Extending laterally of the stationary platform is a support unit for attachment of accessories and including at least one support and a guide bar secured to the frame assembly and configured of polyhedral cross section for guiding the support in longitudinal direction.

Abstract: A satellite receiver is provided which downconverts an incoming band of signals received at a carrier frequency to a signal spectrum centered about an intermediate frequency (IF). The IF signal spectrum is filtered to provide a group of signals therefrom. The group comprises a subset of all the signals in the incoming band of signals. The group of signals from the IF signal spectrum is sampled at a high frequency which is greater than the highest frequency present in the group but lower than the intermediate frequency, in order to provide the group of signals at baseband directly from the IF signal spectrum.

Abstract: The process is intended to establish whether the data transmitted by the transmitter (SE) to the receiver (EM) have been tapped and spuriously reintroduced at a later point in time and/or have been inadmissibly altered. For this purpose, the signature (S) assigned to the useful data (D) is enciphered symmetrically, using a combination of coupling data (K), characterizing the coupling between transmitter and receiver, and random data (Z), generated by a random generator. The coupling data are transmitted in plain text, the random data are enciphered. On the receiver side it can be established whether the transmitted message has been tapped and reintroduced at a later point in time if the coupling data are inadmissible.
