Abstract: A solid-state audio recording unit, capable of checking whether normal audio recording is performed or not on a real-time basis, includes one input buffer for receiving incoming audio data operating at a standard speed, another input buffer for writing audio data into a memory 9 operating at a high speed, one output buffer for receiving audio data from the memory 9 operating at a high speed, and another output buffer for delivering audio data as output operating at a standard speed. As such, it is possible to write/read data into/from the memory at a high speed; and thus operation is ensured enabling, on appearance, parallel processing of input and output, even though, in reality, a single memory is shared by the input and output ports; and thus it becomes possible to deliver audio data stored in a memory as an output on a real-time basis.

Abstract: In a circuit arrangement for operating at least one lamp, and comprising two power feedback loops, a transformer with two primary windings and one secondary winding is included in the load circuit. The voltage present at a common terminal of the two primary windings is fed back by one of the feedback loops. The circuit arrangement can operate lamps with a lamp voltage that is much higher than the rms voltage of the mains supply generating only a limited amount of total harmonic distortion.

Abstract: A heating apparatus comprises a plastic body and a planar heating element, together defining a liquid heating vessel.

Uniform compression of a seal is obtained during the welding process. The weld provides a reliable seal.

Abstract: A system which determines whether to accept a wireless connection to a network device receives a request to initiate the wireless connection to the network device, and then determines, in response to the request, a nominal cell rate at which cells are exiting from a buffer in the network device for the requested wireless connection. Thereafter, the system determines an amount of buffer space in the network device required to accommodate the connection, and decides whether to accept the wireless connection based on the nominal cell rate and the amount of buffer space required to accommodate the connection.

Abstract: Multiword information is encoded as based on multibit symbols in relative contiguity with respect to a medium, whilst providing wordwise interleaving and wordwise error protection code facilities. This may provide error locative clues across words of multiword groups, that originate in high protectivity clue words and point to low protectivity target words. The clue words may have a first uniform size and be interspersed in a first uniform manner. The target words may have a second uniform size and be interspersed in a second uniform manner. The organization may be applied for use with optical storage. Sectors may get provisional protectivity as a low-latency error correction mechanism.

Abstract: A driving circuit for bipolar transistors having a control voltage device for producing a control voltage associated with each transistor. A tertiary winding, serving as the base winding for the bipolar transistors, supplies current to the base of each bipolar transistor based on the associated control voltage. Separate feedback circuits associated with each transistor carry a feedback signal reflecting the minority carrier charge stored in the associated transistor. The control voltage associated with each transistor varies based on the associated feedback signal.

Abstract: A method and a device for bonding a first plate-shaped object to a second plate-shaped object by means of an adhesive. The adhesive is applied to one surface of the first object. Thereafter, said surface of the first object and one surface of the second object are pressed together. The objects are rotated at equal rotational velocities about an axis extending perpendicular to the surfaces of the objects while the two objects are pressed together. The adhesive present between the two objects spreads homogeneously therebetween by the centrifugal force acting on the adhesive. A homogeneous, relatively thin and strong layer of adhesive is formed between the two objects. The pressure is reduced on the objects to be pressed together. In a special embodiment, during a first phase, the two objects are moved towards each other at a predetermined relatively low approach speed, and are rotated at a predetermined relatively low rotational speed.

Abstract: The invention relates to a color display device comprising an in-line electron gun (5) for generating three electron beams (6,7,8), and a convergence unit (14) to dynamically influence the convergence of the electron beams, preferably to decrease a distance (p) between the electron beams. The convergence unit (14) comprises a ring-shaped element (21) having four coils (22) and a longitudinal axis (24). A cross-section of the ring-shaped element (21) with a plane perpendicular to the longitudinal axis (24) is a circle with the longitudinal axis as its center and the ring-shaped element (21) forming the circumference. Each coil extends over the circumference over an angle &phgr; having a value between 50° and 75°.

Abstract: Electro-optical element (shutter) which is switchable between two or more optical states and has a large mechanical rigidity because an extra spacer edge is provided so that no or hardly any spacers are required in the active area. By providing inlet and outlet apertures in the extra spacer edge, contaminations are prevented from being left in the active area during filling. The active area thus remains free from disturbances.

Abstract: A plurality of peripheral devices are interfaced via a Slave Group Interface device to a bus. This allows for the transfer of clock signals, control signals including select signals, and information bits. In particular, the device ORs peripheral read data according to appropriate bit significance levels. In the absence of a write control signal all peripheral write data are maintained at an inconsequentiality level. Various control signals received from the peripheral devices are parallel-compacted to a compacted bus control signalization.

Abstract: The invention relates to a method of manufacturing a high-voltage element, in particular, but not exclusively an LDMOS transistor in SOI with a drift region (13) which has a linearly increasing doping concentration between a back-gate region (8) and a drain (6). A doping mask (15) is used for doping the drift region, in which mask the pitch between the windows becomes smaller in the direction from source to drain at least within part of the drift region. This is achieved in an embodiment by means of windows which have identical dimensions but which lie closer together in proportion as they lie closer to the domain. It was found in experiments that a smooth doping profile can be obtained in this manner, so that peaks in the doping, and thus in the electric field, are avoided. The degree of impact ionization is reduced thereby, which benefits the robustness of the transistor.

Abstract: A device for simultaneously transmitting a plurality of television signals comprises an adjusting circuit (5) for adjusting the bitrate for each television signal in dependence upon the complexity of this signal with respect to the joint complexity of the plurality of television signals. The device provides improvement of quality in Digital Video Broadcast systems. It has also been found to be possible to transmit extra signals through a given channel while maintaining the picture quality. Use of the device in optical recording provides the possibility of a longer playing time.

Abstract: An active matrix electroluminescent display device has an array of current-driven electroluminescent display elements (20), for example comprising organic electroluminescent material, whose operations are each controlled by an associated switching means (10) to which a drive signal for determining a desired light output is supplied in a respective address period and which is arranged to drive the display element according to the drive signal following the address period. Each switching means comprises a current mirror circuit (30, 32, 38) in which the same transistor (30) is used to both sense and produce the required drive current for the display element (20) with the gate of the transistor being connected to a storage capacitance (30) on which a voltage determined by the drive signal is stored. This allows variations in transistor characteristics over the array to be compensated and improved uniformity of light outputs from the display elements to be obtained.
