Abstract: A method of scrolling foreground shapes, for example text, over a background on a display having a line structure or fed from a display memory storing discrete picture elements (pixels) is arranged to give an improved impression of smooth scrolling at rates where movement is not equal to an integral multiple of the pixel line width per frame. This is achieved by detecting which pixels correspond to leading and trailing edges of the shapes and assigning to them distinct colour codes. By updating the entries in a colour look-up (CLUT) the apparatus can modify their luminance (and optionally colour) in dependence on a fractional line position of the shape. The shapes can be pre-stored with the distinct colour codes for edges. In particular, component parts such as text character shapes can be pre-stored and compiled into the desired text.

Abstract: A machine for processing, more specifically mowing and crushing, haulm-like crops, is provided with crusher rollers (35, 36) having adjacently and oppositely arranged conical portions (46, 47) with oppositely directed conical variations. This achieves that the mown haulms are conveyed in different directions through the crusher rollers (35, 36), so that the haulms leaving the crusher rollers (35, 36) in a flow are interweaved. This provides a swath having a coherent crop structure, as a result of which the swath is easier to handle and less losses will occur during the picking-up. 
     In addition, the crusher means (29,64) are constructed in such a way that the crop will be put onto the ground in a number of tunnel-like configurations lying side by side on the ground and extending in the direction of operative travel.

Abstract: An active acoustic attenuation system attenuates a correlated input acoustic wave and eliminates the need for an input transducer sensing such wave. An output transducer (14) introduces a canceling acoustic wave to attenuate the input acoustic wave and yield an attenuated output acoustic wave. An error transducer (16) senses the output acoustic wave and provides an error signal (44). An adaptive filter model (M) has a model input (202), a model output (204) outputting a correction signal (46) to the output transducer (14) to introduce the canceling acoustic wave, and an error input (206) from the error transducer (16). A summer (208) has a first input (210) from the model output (204), a second input (212) from the error transducer (16), and an output (214) outputting a resultant sum to the model input (202), such that the model input (202) is provided by the sum of the correction signal (46) and the error signal (44).

Abstract: In a digital telecommunication system, an existing emergency-operation connection is intended not to be interrupted when it is possible to switch back to normal operation because, for example, the power supply system is again available. It is intended that there should be no need to wait until the existing emergency-operation connection is cleared down. It is intended for the method to be usable regardless of the type and size of a digital telecommunication system. An emergency-operation control device is provided which detects the failure and restoration of the power supply and, when the power supply is restored, a corresponding back-up circuit is set up within the telecommunication system. The direct connection is cleared down only when this back-up circuit has been set up. The interfaces involved in the back-up circuit are then switched to a connection condition of the type which prevails in normal operation. The same method can be used economically in all types of digital communications switching systems and other telecommunication systems regardless of their size. Standardised command structures are used in the exchange of signalling information. <IMAGE>

Abstract: Electrical energy can be transmitted from a 50 Hz national grid (7) to a 16 2/3 Hz railway network (1), and vice versa, via a converter having a DC voltage intermediate circuit (3). A special case is the operation of a converter having an impressed DC voltage without real power being transmitted. In this case, a DC voltage intermediate circuit (3) is terminated by an intermediate circuit capacitor (C1, C2) and possibly by a high-pass filter (4). Converters having an impressed DC voltage produce an AC voltage by switching the DC voltage over section by section to the load on the AC side and to a network connection (1) on the AC side. The AC voltage which is produced by converter elements (ST1 - ST3) of the converter and is mutually phase shifted is supplied into the railway network (1) via series connected transformer elements (Tr1 - Tr3). In order to reduce interfering harmonics produced during the pulsing of the converter elements (ST1 - ST3), the rectangular waveform of voltage elements produced by the converter elements (ST1 - ST3) must be added in the transformer elements (Tr1 - Tr3) to produce a staircase waveform such that the staircase waveform corresponds as well as possible to a desired sinusoidal waveform. In order to achieve this, voltage step ups of the transformer elements (Tr1 - Tr3) are graduated such that the resulting jumps in the overall or sum voltage are proportional to cos  alpha i,  alpha i indicating a phase shift of an ith voltage jump related to the voltage zero crossing. <IMAGE>

Abstract: A wiper blade cleaning system has two polyurethane wiping blades (30,31) of unequal lengths, but which are otherwise identical. The blades are releasably mounted in slots on a planar surface of a fixed structural member (32). The mounted blades are parallel and spaced apart a predetermined distance (X). The positioning of the blades is dependent on the order in which they must act on the nozzle face of the printhead as it leaves the priming station, so that the shorter blade (31) cleans first. The shorter blade is stiffer because of its shorter length and serves to remove ink efficiently off of the printhead nozzle face (23). However, when cleaning a non-coplanar nozzle face, small amounts of ink collected on the shorter blade cleaning edge may be deposited in crevices or other discontinuities (87) on the non-coplanar nozzle face. The longer blade (30) is more compliant because of its added length and follows in the wake of the shorter blade to remove the last vestige of ink left by the stiffer, shorter blade.

Abstract: An integrated circuit architecture and test methods for use in designing, fabricating and testing mixed-signal application specific integrated circuits. The architecture comprises a plurality of mixed-signal integrated circuits (11a-u), bidirectional buffers (17) coupled to the integrated circuits that provide for circuit reconfigurability, a bidirectional digital/analog test bus (15), and a serial test controller (21) coupled to the buffers that controls normal operation and testing of the integrated circuits. The controller and plurality of buffers cooperate to couple signals from signal pads (16) to the integrated circuits to provide for "normal" operation thereof, and to re-route external test signals applied to selected signal pads to the integrated circuits to permit testing. Logic in the buffers provides for functional configurability, enabling them to be logically altered under control of the controller, and allowing the test bus to be connected directly to signal pads. All of the signal pads are available for use in testing, and provide a means of directly accessing key test points within the circuit without resorting test vectors. Test methods are disclosed and comprise: selecting an integrated circuit for testing; selecting signal pads that are to be used to test the selected integrated circuit, which selected signal pads are different from those used during normal operation of the integrated circuit; applying external test signals to the selected signal pads; routing the external test signals by way of the plurality of configurable buffers and the bidirectional bus from the selected signal pads to the integrated circuit; and monitoring input signals and output signals applied to and derived from the selected signal pads to test the selected integrated circuit.

Abstract: A toy doll with lips (35) that move as speech sounds are produced from a speaker (24). Pressing a button (22) on the body of the doll activates an integrated circuit (26) that sends voice signals to the speaker, which transmits the sounds. This in turn actuates a switch, causing a motor (28) to run. The drive shaft of the motor rotates, causing a series of meshing gears to turn. The axle of a said gear that passes through the eccentric bore of an internal cam (30) causes the cam to move so that it forces an L-shaped cam follower (32) to rock back and forth about a pivot point. The rotatable pivot rod is supported by the rigid torso of the doll, and one end of the cam follower is attached to the interior of the doll's flexible face at a point connecting the two lips (35). The rocking of the cam follower causes the lips to close and open in a simulation of talking. The motor only runs, and consequently the lips only move, at the same time that simulated speech is transmitted from the speaker. A portion of the doll's rigid body that is interior to its flexible head supports the head and prevents the head and face from collapsing or becoming distorted during operation.
