Abstract: The subscriber feed voltage applied in the subscriber connection circuit (SLIC) is dependent on the length of the subscriber line (TL). To generate a ringing signal, a voltage with the polarity (+UZ) opposite to the polarity of the feed voltage (-UB) is connected. So that the ringing signal voltage is independent of the length-related amplitude of the feed voltage, the voltage to be connected (+UZ) is generated with the aid of a switched-mode controller (OP1, OP2, OP3) which maintains a constant difference voltage. <IMAGE>

Abstract: A display module having a housing constructed to mechanically interlock with the housings of adjacent modules of like construction to form a multiple unit display having either a single display row, or a cluster having first and second display rows. The modules of a display row interlock via male and female dove tail extrusions integrally formed with the module housings, while modules of adjacent first and second display rows interlock via cooperative projections and recesses integrally formed with the module housings and via a common electrical conductor which mechanically and electrically interconnects electrical terminals of adjacent display rows to hold the first and second display rows in assembled relation while simplifying electrical connections to the cluster. A single mounting projection per housing provides support for mounting a row or cluster to a face plate, by selection of predetermined orientations of the modules.

Abstract: A technique for assembling semiconductor devices in which semiconductor elements, especially lasers or LEDS, are mounted on a first packaging element such as a heat spreader that is mounted on a second packaging element such as a heat sink. Handling of solder preforms is avoided by coating at least one of each of the pairs of surfaces to be brought into contact with a layer of solder and heating the assembly to melt both solder layers in a single operation. In a preferred embodiment a heat spreader is coated in solder on both sides and interposed between a semiconductor element and a heat sink and the assembly is heated. Molybdenum may be used as a layer to aid wetting and adhesion and gold/tin solder may be used. Slightly different solidification temperatures and compositions for the layers may result from different take up of metallisation layers from the components into the solder.

Abstract: The functions of two virtual operating systems (e.g. S/370 VM, VSE or IX370 and S/88 OS) are merged into one physical system. Partner pairs of S/88 processors run the S/88 OS and handle the fault tolerant and single system image aspects of the system. One or more partner pairs of S/370 processors are coupled to corresponding S/88 processors directly and through the S/88 bus. Each S/370 processor is allocated form 1 to 16 megabytes of contiguous storage from the S/88 main storage. Each S/370 virtual operating system thinks its memory allocation starts at address 0, and it manages its memory through normal S/370 dynamic memory allocation and paging techniques. The S/370 is limit checked to prevent the S/370 from accessing S/88 memory space. The S/88 Operating System is the master over all system hardware and I/O devices. The S/88 processors across the S/370 address space in direct response to a S/88 application program so that the S/88 may move I/O data into the S/370 I/O buffers and process the S/370 I/O operations. The S/88 and S/370 peer processor pairs to execute their respective Operating Systems in a single system environment without significant rewriting of either operating system. Neither operating system is aware of the other operating system nor the other processor pairs.

Abstract: An encoder applies a digital filterbank such as a transform or subband filterbank to an input signal to generate frequency subband information, encodes the resultant subband information using adaptive bit allocation to generate fixed-length values represented by fixed numbers of bits and variable-length values represented by variable numbers of bits, and formats the subband information into an encoded signal in which the fixed-length values are assembled into preestablished positions within the encoded signal. In response to an encoded signal including subband information represented by fixed-length values and variable-length values, a decoder extracts fixed-length values represented by fixed numbers of bits from preestablished positions within the encoded signal, extracts variable-length values represented by variable numbers of bits, wherein the variable numbers of bits are established in response to fixed-length values, and generates an output signal by applying an inverse filterbank to the extracted subband information. <IMAGE>
