Abstract: Method and System For Synchronizing Block-Organized Data Transfer Amongst a Plurality of Producer and Consumer Stations. With respect to a particular facility semaphore-based synchronizing is executed among a first station and one or more second stations. For each station a single bivalent semaphore is provided. The first station checks all second station semaphores as having a second state relative to its own semaphore's first state. It then executes a first accessing operation and flips the first state. Otherwise it foregoes the first accessing operation. Any second station checks the first station semaphore as having the second state relative to its own semaphore's second state. It then executes a second accessing operation and flips the latter state. Otherwise it foregoes the second accessing operation.

Abstract: The invention relates to a receiver for a digital transmission system with an incoherent transmission method, which receiver includes an equalizer for forming estimates for a sequence of symbols a[k] transmitted by a transmission channel from received symbols r[k] by means of an impulse response h[k] that describes the transmission properties. For improving the receiving quality in an incoherent transmission method and transmission channels having intersymbol interference, it is proposed that the equalizer performs an incoherent maximum likelihood sequence estimation (MLSE) method to determine the estimates â[k] for the sequence of transmitted symbols a[k]. In channels having intersymbol interference, the incoherent MLSE method provides clearly better results than all the known incoherent receiving methods. As against frequency and phase offset, the incoherent MLSE method is considerably more robust than all the known coherent receiving methods.

Abstract: The invention relates to a magnetic tape (10) formatted by means of a magnetic emboss head (60), and an apparatus comprising a magnetic data head (20) which is movable in a transverse direction (y) by means of an actuator (40).

Abstract: A radio device includes phase discriminator with a phase locked loop. Where when there is no phase locking, the output voltage of the phase discriminator remains constant, which provides considerable gain for loop. When there is phase locking, the phase discriminator produces an error proportional to the phase difference. An output of the phase discriminator has a constant amplitude with an input signal and a reference signal have different frequencies.

Abstract: A backlight system comprises at least two light-emitting panels (1; 11) having a front wall (2; 12), an opposing rear wall (3; 13) and opposite edge surfaces (4, 14; 5, 15). At least one of the edge surfaces (4; 14) is light-transmitting and associated with a plurality of light sources (6, 16). Light originating from the light sources (6; 16) is diffused in the panel (1; 11). Sub-surfaces (8, 18) of the rear walls (3, 13) are provided with means for extracting light from the panel (1, 11). In operation, said sub-surfaces (8, 18) project light on areas (9, 19) of an (imaginary) plane (40) which is positioned parallel to the light-emitting panels (1, 11). Said projected areas (9, 19) in the plane (40) are substantially contiguous. Preferably, said sub-surfaces (8, 18) are remote from the light-transmitting edge surfaces (4; 14). Preferably, each of said sub-surfaces (8, 18) forms a single surface covering half the front wall (2, 12) of the light-emitting panel (1, 11).

Abstract: In a system for the transmission of data between at least one write/read station and a plurality of data Carriers, inductive coupling is used to transmit energy and clock pulses from the write/read station to the data carrier. Data is transmitted either in the opposite direction only or bidirectionally. The data carrier in accordance with the invention is provided with a random number generator (6) which can store a random number in a memory (3), preferably under the control of the write/read station. If this random number forms part of the code to be transmitted by the data carrier, a so-called rolling code access control system can be simply implemented, that is to say an access control system in which the codes are changed at regular intervals.

Abstract: A method of manufacturing a semiconductor device with a MOS transistor having an LDD structure. A gate dielectric (6) and a gate electrode (7, 8) are formed on a surface (5) of a silicon substrate (1). The surface adjacent the gate electrode is then exposed, and a layer of semiconductor material (10) is formed on an edge (9) of the surface adjoining the gate electrode. Ions (13, 14) are subsequently implated, with the gate electrode and the layer of semiconductor material acting as a mask. Finally, a heat treatment is carried out whereby a source zone (16, 17) and a drain zone (18, 19) are formed through activation of the implanted ions and through diffusion of atoms of a dopant from the layer of semiconductor material. The portions (b) of these zones formed by diffusion are weakly doped here and lie between the more strongly doped portions (a) formed through activation of implanted ions and the channel zone (20, 21). An LDD structure has thus been formed.

Abstract: Visible defects are detected on a process semiconductor wafer. Defects are classified according to appearance and an association is kept between classes and apparatuses. When the density of defects in a given class exceeds a control limit the associated apparatus is switched off-line. In an embodiment, the same wafer is inspected repeatedly, each time after a different processing steps and information about the location of detected defects is kept. Defects which occur at a location where defects have already been detected in a previous inspection after an earlier processing step are eliminated from the density which is compared to the control limit.

Abstract: Apparatus for treating substrates, such as silicon wafers (1), wherein the substrates are immersed for some time in a bath (2) containing a liquid (3) and are taken therefrom so slowly that practically all of the liquid remains in the bath (2). The substrates (1) are brought from the liquid (3) directly into contact with a vapor of an organic solvent which is mixed with a carrier gas and introduced from gas leads (17) having outlet nozzles (18). The vapor is miscible with the liquid (3) to yield a mixture having a surface tension lower than that of the liquid, and which does not condense on the substrates. No drying marks with organic or metallic residues or other contaminations remain on the substrates (1).

Abstract: Human speech is coded by singling out from a transfer function of the speech, all poles that are unrelated to any particular resonance of a human vocal tract model. All other poles are maintained. A glottal pulse related sequence is defined representing the singled out poles through an explicitation of the derivative of the glottal air flow. Speech is outputted by a filter based on combining the glottal pulse related sequence and a representation of a formant filter with a complex transfer function expressing all other poles. The glottal pulse sequence is modelled through further explicitly expressible generation parameters. In particular, a non-zero decaying return phase supplemented to the glottal-pulse response that is explicitized in all its parameters, while amending the overall response in accordance with volumetric continuity.
