Abstract: 2.1 In an optical duplexer for bidirectional information transmission, the aim is to produce a phase difference between two optical waves, which are retroreflected to the duplexer along different optical paths (W L2, W L3), in order to reduce near-end crosstalk while avoiding the production of a wavepath difference between the two paths. 2.2 For this purpose, a device (PS) is provided to control the phase of an optical wave retroreflected into the duplexer on one of the two paths, or the two paths have an optical wavelength difference produced by a difference in refractive index. In particular, it is favourable for the phase difference between the optical waves retroreflected into the duplexer on the two paths to be set or fixed at /2. 2.3 Application in bidirectional information transmission. <IMAGE>

Abstract: Overvoltage protecting device to protect electrical equipment on board a vehicle against overvoltages, in which a level exceeding an overvoltage threshold and subsequently falling below a low voltage threshold are identified and evaluated with the aid of an evaluation circuit (K1, K2). The occurrence of the respective evaluation signal is retained in a storage device (39) until the occurrence of the respective other evaluation signal. If the evaluation signal stored indicates that the overvoltage threshold has been exceeded, the generator is short-circuited by means of a switching transistor device (27). If the evaluation signal subsequently fed into the storage device (39) indicates that the level has fallen below the low voltage threshold, the switching transistor device is switched back to the non-conducting state and the generator short-circuit is thereby cancelled.

Abstract: A database index file is maintained by a computer system having primary random access memory and secondary memory. A record for each item added to the database is stored in a sequential file in secondary memory (disk storage) and an indexed pointer to the new record is stored in a small B-tree stored in primary random access memory. The full index file for the database is a second, large B-tree stored in secondary memory. Leaf-nodes of the full index file are stored in indexed order. Periodically, a portion of the memory resident small B-tree is merged with a corresponding portion of the large B-tree by selecting a range of index values and retrieving from secondary memory all indexed pointers in the selected range of index values. The indexed pointers in the first B-tree in the selected range of index values are merged into the retrieved records, the resulting merged set of indexed pointers are stored in secondary memory in indexed order in a contiguous area of secondary memory. As a result, the indexed pointers for newly added database records are written to secondary memory in batches, thereby accessing secondary memory very efficiently.
