Abstract: An apparatus and a method for packet error correction in packet-switched networks is provided. Message packets to be transmitted on a network are subdivided into k symbols over GF(q), and the symbols are then encoded by a symbol-level encoder into a codeword of n>k symbols over GF(q). The codeword is transmitted on the network in a plurality of network packets to a symbol-level decoder, which recovers any symbols lost or corrupted in transmission. Encoding at the symbol level increases the amount of data that can be recovered in any single correction operation. The efficiency of the decoding is also enhanced because the location of symbol errors can be determined prior to decoding.

Abstract: In particular, Compounds of Formula I or Formula II, generally known as calix[4]arenes, may be prepared. The compounds may be used to test samples for the presence of Hg2+ by fluorescence quenching. The compounds may also be used to selectively detect Hg2+ in samples containing other mono- or divalent metals.

Abstract: The present invention relates to a hinge joint mechanism. The hinge joint mechanism comprises a fixed component including a plurality of curved portions and at least one straight portion; a movable component including a plurality of curved portions and a plurality of straight portions; said hinge joint mechanism provides a relative rotation between the two surfaces of the hinge joints to rotate the movable component by a desired amount relative to the fixed component. The hinge joint mechanism of the invention provides a proper sealing in the joints to avoid liquid or any such kind of material to move across it.

Abstract: This invention provides an apparatus and a method for folding and unfolding a foldable transport container automatically. The apparatus comprises plurality of moving parts (P1, P2) and arms (A1, A2, A3, A4) to fold the sides (FS1, FS2) of the container and to fold the top (T) and bottom (B) of the container. Said moving parts and arms are operated by plurality of actuators (H1, H2, H3, H4).

Abstract: A foldable transport container is provided which substantially folds horizontally against a side wall (SSI) and in which the process of folding can be facilitated using external automatic apparatus.

Abstract: The invention provides a T-connected autotransformer for converting three-phase ac input voltages to nine phase shifted ac voltages feeding three sets of three-phase diode rectifier bridges. The nine phase shifted voltages are at an angle of +20 degree or ?20 degree with respect to the supply voltages and their magnitudes are essentially identical. The present design requires substantially fewer coils than other autotransformers for 18-pulse AC-DC converters, resulting in saving in space, volume, weight, size and cost of the converter. The magnetics requirement is only about 30% of the drive rating. The output voltage ratio can also be selected to give an average dc output from the proposed converter same as that of a conventional three-phase diode bridge rectifier. However, it is also possible to step up or step down the output voltage as required.

Abstract: The present invention discloses a relaxor material lead iron tungstate which has been synthesized in doped and undoped conditions by single and two step heat treatment. The relaxor material is seen to exhibit almost negligible hysteresis and a transducer made thereby shows pressure measurement capability over a wide range from 0.5 MPa to 415 MPa with accuracy of ±0.05%.
