Abstract: A digital data sequence is mapped into a singal point sequence for data transmission over a channel characterised by a non-ideal response. The signal point sequence is selected from a subset of all possible signal point sequences based on the digital data sequence and upon the response. All possible signal point sequences in the subset lie in a fundamental region of a filtered trellis code. This fundamental region is other than a simple Cartesian product of finite-dimensional regions.

Abstract: The present invention involves methods of improving LCR and PCR amplification schemes by modifying at least one probe/primer end so that the probability of the probe/primer contributing to spurious signal development is greatly reduced. Only after specific hybridization of the modified probe/primer with true target, are the modified ends "corrected" in a target dependent fashion to allow participation of the probe/primer in the enzymatic assembly reaction. Specific modifications depend on whether the assembly is done by ligation (as in LCR) or by extension/elongation (as in PCR). <IMAGE>

Abstract: A method of extending the useful life and/or enhancing the performance of wet or dry lithographic printing plates. A strong curable composition that adheres to the ink-receptive plate areas is first applied to an imaged plate. After removal of the composition from non-image plate areas, it is cured, thereby augmenting the resilience of the ink-receptive plate areas. If imaging of the plate results in surface recesses, the cured composition can enhance plate performance by making the entire surface coplanar.

Abstract: An antenna construction with a rod-shaped antenna element is adapted for use preferably in portable telephones. The rod-shaped antenna element is adapted to be slidably moveable in a tube between a first position in which substantially the entire rod-shaped antenna element protrudes from the tube and contributes to radiation, and a second position where just part of the rod-shaped antenna element protrudes from the tube and contributes to radiation. The rod-shaped antenna element is adapted to be received in the tube to provide a coaxial transmission line. The coaxial transmission line is adapted such that in the second position where part of the antenna element is received in the tube, it has a length and is terminated in a manner such that the impedance of the transmission line is high seen from the protruding part of the antenna element and thus does not affect this part. The coaxial transmission line may e.g. be an open half-wave transmission line. However, the transmission line may also be realized in the form of a short circuited quarter-wave transmission line or an open, shortened half-wave transmission line.

Abstract: 3- or 4-Mono-, 1,3- or 1,4- or alternatively 3,4-disubstituted derivatives of quinic acid are prepared by reacting a derivative of a hydroxycinnamic acid, in which the phenol group(s) is(are) protected, with a quinic acid derivative so as to form an ester, taking advantage of the different reactivities of the OH functional groups in the 3 and 4 positions in order to carry out the esterification selectively under low temperature conditions, and then the protective groups are cleaved under controlled acidity and temperature conditions. These conditions prevent any degradation or isomerisation. The process makes possible the preparation of new quinides with a good yield.

Abstract: Method and apparatus for effecting mode switching from a transmission mode to a command mode of an intelligent modem operatively coupled to a digital data device and a telephone line is disclosed. A termination of the modem's transmission mode is effected after a predetermined silent time interval in which no data is received from the device and prior to the transmission of additional data on the line. Operation of the modem switches to a buffer mode in which data sent from the device is temporarily stored instead of being transmitted on the telephone line. If the stored data is a proper escape sequence, operation of the modem switches to the command mode. If a proper escape sequence is not received, operation of the modem switches to a purge mode in which the stored data is transmitted on the telephone line. The apparatus comprises a data interface, a novel modem controller and a modem engine. The modem controller includes the data buffer for storing the data received from the digital data device when operating in the buffer mode.

Abstract: A nozzle for an ink-jet printer is provided having a gradually converging inner diameter leading to an orifice less than 15 microns in diameter and having an outer nozzle diameter proximate the orifice at least as great as the outer diameter at other points along the nozzle. The nozzle is produced by heating a vitreous tube while rotating it, until a portion of the tube is sufficiently viscous to cause the inner diameter to converge at an angle between 5 and 25 degrees with respect to the axis of symmetry of the tube, and until the inner diameter is less than a selected orifice diameter. The gradual taper is achieved without drawing or pulling the tube and it facilitates achieving a desired orifice dimension during removal of a portion of the tube having an inner diameter less than the selected orifice diameter. The extremely small orifice size enables an ink-jet printer to deposit droplets of ink sufficiently small to make photographic-quality gray scale and color images. <IMAGE>
