A number of characters of the password are set in accordance with the duration of the first operating state of the device.

Abstract: Uncoded geographical image data for a pre-defined geographical region is stored in a server unit and at least one wireless communication interface is provided between the server unit and at least one navigation receiver module. At least one position information message is transmitted from the navigation receiver module to the server unit and an expectancy range is selected in the server unit according to the transmitted position information from the pre-defined geographical region. Uncoded geoimage data reproducing the expectancy range is determined and the first uncoded geoimage data is encoded in the server unit. The encoded geoimage data is then transferred to the navigation receiver module from the server unit via the wireless communication interface.

Abstract: A method and an apparatus protect location-related messages which are transmitted from a provider to a plurality of temporally changing recipients and receiver devices in a plurality of localities in each case. The method and apparatus are distinguished by the fact that key certificates for signed messages are issued only in a location-related manner and are thus valid only in a particular defined local environment.

Abstract: In a method and device to automatically update a computer system, such as a controller for industrial systems, which has multiple components, at least one component of the computer system to be updated is associated with a criticality domain from a number of predetermined criticality domains. A criticality level from a number of predetermined criticality levels is associated to at least one software update provided for one of the components of the computer system. The software updates are automatically transferred to the corresponding components of the computer system according to the criticality domain associated with the component, and according to the criticality levels assigned to the software updates.

Abstract: The invention relates to a method for managing a display device (DSP) of a portable communications device (MFG) having the following characteristics: said display device is used for displaying graphical subject matter, it also comprises a processing device (LAE) for carrying out first and second applications, each of which has an output subject matter. A control device (IM) for managing the graphical display surface of the display device is also provided, wherein the control device of the first application allocates a first display area and the control device of the second application allocates a second display area in such a way that no overlap of said display areas is produced, thereby avoiding the harmful influence of the first performed application on the second later invoked application.

Abstract: The voice of a synthesized voice output is individualized and matched to a user voice, the voice of a communication partner or the voice of a famous personality. In this way mobile terminals in particular can be originally individualized and text messages can be read out using a specific voice.

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: The present disclosure relates to a communications device including a memory unit for storing image data and telephone book entries and a processor unit. Said processor unit is configured to favor image data containing information that describes faces.

Abstract: A technical function that is of interest for mobile or stationary communication terminals is the playing of a video of the corresponding person when a call is received. However, the playing of a video during an incoming call is associated with highly complex processes, as the stored videos have to be decoded in real time. The object of the present invention is therefore to specify a method, which reduces the required computing power and storage capacity. The object is achieved by a method in which an image of the calling person is animated by a face animation algorithm.

Abstract: What has become a widespread function in mobile or stationary communication terminals is taking pictures using cameras integrated in the mobile communication terminals. The pictures are taken sideways or upright depending on the specific situation, but other orientations also occur. Once taken, the pictures can be displayed directly on small screens or used by further applications. If slanted pictures have been taken a user will have to turn the mobile communication terminal to be able to view the face in its correct position. Moreover, face animations using pictures that have been taken are extremely difficult if the faces shown in the pictures are not in vertically oriented positions. To resolve this problem a method determines an optimized orientation of the picture by applying a face-localizing method.

Abstract: Text information regarding audio and/or video data is assigned to phonemes by grapheme-to-phoneme conversion and used as the vocabulary of a speech recognition device.

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: The voice of a synthesized voice output is individualized and matched to a user voice, the voice of a communication partner or the voice of a famous personality. In this way mobile terminals in particular can be originally individualized and text messages can be read out using a specific voice.

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.
