Abstract:
There is known a telecommunication terminal with a miniature display for received, visually perceptible information, such as, for example, fax messages. In addition, a device is known for projecting computer images or TV images, the device comprising a so-called DMD chip (Digital Mirror Device). It is proposed to improve the aforedescribed telecommunication terminal (MS) by providing the terminal with projection means (DMD, FL) which can basically only be used for the device described above. In addition, the device described above is improved by being provided with an interface circuit for connection to a telecommunication terminal. Accordingly, the conventional means known in the field of computer technology and TV technology for projecting images are now used in or for a telecommunication terminal, especially in a mobile radio telephone (MS). With the received image data, images can be projected directly onto a projection screen, for example, onto a wall. Several people can view the images simultaneously. An output device, such as, for example, a printer for fax messages, is not required.
Abstract:
Call connections by way of the Internet (internet telephony) are less expensive than ones by way of an open telephone network. However, no fixed transmission rates are guaranteed in the Internet, which can lead to losses in the quality of transmitted speech signals. A device (V) for establishing a call connection between two subscriber terminals (T1, T2) has a first interface (IF1) to a packet-switched data network (INET) and means (IP, KOMP) for establishing connections by way of the packet-switched data network (INET) as well as a second interface (IF2) to a connection-oriented telecommunication network (PSTN), in which a transmission channel with a predetermined transmission band width can be furnished. By means of a monitoring device (MON), the device (V) determines a current data throughput in the data network (INET). A control device (SW) of the device (V) compares the current data throughput with a predetermined threshold value and controls the establishment of connections in such a way that the call connection is established by way of the data network (INET) when the data throughput lies above the threshold value and is established by way of the telecommunication network (PSTN) when the data throughput lies below the threshold value.
Abstract:
An initiating processing unit is normally occupied during the programming of flash EEPROMs. The time of occupation becomes ever longer with increasing age and degree of utilization of the flash EEPROMs. Here, the processing unit uses an initiatable interrupt routine, which triggers a programming of the flash EEPROM and is then terminated in order to use the programming to further process a main program at the same time. A timer function in a processing unit is used to trigger an interrupt routine. The interrupt routine checks the initial conditions and in the case when an initial condition has been fulfilled, the programming of the flash EEPROM is triggered, whereupon the execution of the main program continues in the processing unit during the programming.
Abstract:
To determine the degree of correspondence between a first and a second pattern, the first and the second pattern are mapped to n first (V11 to V1n) and m second (V21 to V2m) feature vectors respectively. For points ({1, 1} to {n, m}) in a subarea of a matrix formed by the n first (V11 to V1n) and m second (V21 to V2m) feature vectors, the distance of the respective first (V11 to V1n) and the second (V21 to V2m) feature vectors is computed, and from the mean distance along an optimum path by means of a DP algorithm. Data regarding the gradient of the respective optimum path are determined during the computation for boundary points of the subarea, and the subarea is dynamically reduced for further computations on the basis of these data. The mean distance is used as the degree of correspondence.
Abstract:
The present invention is directed to a circuit arrangement for connecting a voice-controlled additional facility associated with a telephone station to a telephone line. According to the invention a telephone station (32) is connected with a voice-controlled additional facility (2). The additional facility (2) performs voice-controlled telephone dialing and/or voice-controlled operation of a videotex terminal. This is implemented by a connection unit (14) inserted in the telephone line (16). The connection unit (14) cooperates with the exchange to permit calls to be initiated, in the known manner, by means of a keypad at the telephone station (32). Any type of telephone station (32) can be connected to the voice-controlled additional facility (2) without any engineering modifications.
Abstract:
In a telephone switching system, a multifrequency code receiver unit is replaced by a voice-controlled dial signal receiver unit connected to the switching network via an adapter unit. The voice-controlled dial signal receiver unit contains a voice recognition unit, a voice output unit, and a control unit. A multifrequency code receiver is connected in parallel with the voice-controlled dial signal receiver unit and coupled to the adapter unit. The subscriber can enter dial information and service-feature-control information through the microphone of the handset of a telephone station and/or through a numeric keypad of the station. Instead of being informed of the respective line condition by tone signals, the subscriber receives this information in the form of speech from the voice output unit.
