Abstract: A dual-axis gyroscope (28) and inclination transmitters (46, 48) are arranged in the stabilising element (24) of a dual-axis platform (10). The actuating motors (18, 23) of the platform (10) are controlled from taps (36, 42) on the gyroscope (28). The signals of the inclination transmitters (46, 48) are connected to an optimum state estimator (54). The state estimator (54) supplies estimated values for attitude errors of the stabilised element. These estimated values of the attitude errors are connected to an optimum controller (56). The actuating signals of the controller (56) are connected to in each case one torque generator (40, 44) of the gyroscope (28). <IMAGE>

Abstract: Pressurised railway carriages are used on high-speed rail routes in order to protect the passengers from ear discomfort which may arise due to pressure surges at tunnel entrances and exits or when trains pass one another. Since the pressure tightness of the carriages decreases over the operating lifetime, a diagnosis method is required to determine when a carriage has to be resealed. The invention describes a method of this kind and a technical means of implementation which also takes into account pressure changes due to weather or altitude. <IMAGE>

Abstract: Modulation-doped quantum well heterostructures are cascaded in a semiconductor device to achieve high speed operation while obtaining large index of refraction or absorption coefficient changes for modulating lightwave signals without significant increases in the operating potentials over prior quantum well structures. Each modulation-doped quantum well heterostructure exhibits substantially equal boundary conditions in an unbiased condition for efficient cascading or stacking. Each quantum well (43) has associated with it a barrier layer (44,45,46) to minimize leakage current. As a result, each quantum well has associated with it a separate charge reservoir. This aspect contributes to the speed of the cascaded structure. When incorporated within a waveguide structure, cascaded modulation-doped quantum well heterostructures can act as an external modulator, or as an intra-cavity wavelength tuning element, or as an intra-cavity modulator, or even as an optically-pumped laser.

Abstract: A digitally tuned optical frequency synthesizer includes a laser control arrangement for tuning the laser (51) over a range of frequencies. The laser is tunable in response to different magnitudes of injected bias current. A digital processor (75) determines bias current values which produce the desired different operating frequencies corresponding to a set of resonant frequencies of a Fabry-Perot resonator (56). Those current values are stored in the digital processor for ready retrieval. During operation, one of the bias current values is retrieved and is applied to the laser. If the laser characteristic curve has drifted, an incremental bias current is determined and is added to the retrieved bias current value. For future use, this new bias current value is stored in the digital processor in place of the originally retrieved bias current value. The digital processor additionally calculates new bias current values for all of the desired frequencies of operation and stores those new values for subsequent selection.

Abstract: In the breakable adhesive bonds, the bond of the two parts which are connected to one another is brought about by means of at least one adhesive bead applied between them. The said parts have a heatable separating element, for example an electrically conductive plastic layer, on or in the adhesive bead or one of the adhesive beads, which element eliminates or destroys the bond at the parts which are in contact and at the same time releases the parts of the respective adhesive bead which are in contact when heated to a temperature at which the respective adhesive bead is not yet damaged. In adhesive bonds which have two adhesive beads, one adhesive bead can also be constructed itself as a separating element of this kind. Breakable adhesive bonds of this kind are particularly suitable for the adhesive fitting of vehicle windows in bodies and can be easily separated when the vehicle is repaired or disposed of. <IMAGE>

Abstract: A compensation method and apparatus which achieves, despite parasitic voltage drops caused by a portion of all heating elements in a print line, the desired print density for a given heating element or pixel when multiple heating elements are enabled. A weighted average of the desired digital level of all heat elements in a print line is used to determine an offset power level, which then is used to compensate for power variations at each heat element by adjusting the number of digital signals to each heating element according to the offset power level. This adjustment results in an actual achieved print density that is equivalent to the desired density, despite complications caused by print lines having different desired densities but equivalent density averages.

Abstract: The efficiency and freedom from cross-talk achieved by transmissive multiplexer/demultiplexer devices is achieved in a reflective multiplexer/demultiplexer device. The reflective geometry avoids the large size devices necessitated by transmissive geometries handling a large number of optical channels. The reflective geometry also avoids long bends in waveguides used in optical gratings in high efficiency transmissive geometries. 
     Integrated optical multiplexer/demultiplexers in accordance with this invention comprise a plurality of waveguides for carrying unmultiplexed optical signals (20,22,24) interleaved with a plurality of waveguides for carrying multiplexed optical signals (26,28). The two pluralities of waveguides are connected to the boundary of a free space region (14). The pluralities of waveguides communicate through the free space region with an optical grating comprising a plurality of waveguides (30,32,34) each terminated in a reflective element (36,38,40). The length of each waveguide in the grating differs from the lengths of adjacent waveguides in the grating by a predetermined amount (l) to introduce predetermined path length differences for the optical signals traveling in the waveguides of the grating. 
     Unmultiplexed optical signals, introduced into one or more of the input waveguides (20,22,24) for carrying unmultiplexed optical signals, travel through those waveguides into the optical grating and are reflected towards one or more of the output waveguides for carrying multiplexed optical signals (26,28). When the device is used as a multiplexer in this fashion, it causes the optical signals introduced into the device to be multiplexed together and appear in a predetermined one or more of the waveguides for carrying multiplexed signals. Multiplexed optical signals introduced into one or more of the waveguides for carrying multiplexed signals are directed through the free space region to the optical grating and are reflected toward one or more of the output waveguides for carrying unmultiplexed optical signals. When the device is used as a demultiplexer in this manner, input signals which comprise a mixture of optical frequencies are demultiplexed so that the individual optical frequencies are separated from one another and appear at one or more predetermined waveguides for carrying unmultiplexed optical signals.
