Abstract: The circuit arrangement contains a memory (1), an address controller (3) and a correlator (2), known per se. …<??>The circuit described is to be used for reducing the computing effort for determining similarity functions. The correlation function is an example of a similarity function. The two functions are present in digital form. The samples are stored in the addressable memory (1). The address controller (3) first generates addresses with the aid of which the functions stored in the memory (1) are read out undersampled. Using these undersampled functions, the extremal values and their positions are determined in a first step by the correlator (2) and the address controller (3). In an environment of an extreme determined in this manner, the variation of the similarity functions in this environment are now examined in more detail with a lower undersampling and the extreme is again determined in this environment. This process can be repeated with ever reducing undersampling. …<IMAGE>…

Abstract: Optically nonlinear device elements such as directional couplers, switches, frequency stabilizers, optical parametric devices and modulators use as an optically nonlinear element a cross-linked triazine polymer containing a covalently bonded optically nonlinear dye moiety. A specific cross-linked triazine with this dye moiety may be made by cyclotrimerizing a p-(N,N-bis(4′-cyanatobenzyl)amino)-p′-(2,2-dicyanovinyl)azobenzene monomer. During polycyclotrimerization or cure, the element is subjected to a poling voltage which aligns the dipoles of the dye moiety to give a large useful nonlinear susceptibility.

Abstract: A Process Control Framework is disclosed as an environment in which processes and their products can be formally defined as objects in a machine readable form, called a Process Control File. The Process Control File is used by a Process Control to determine the next action to be performed on the set of objects selected by the user. Where the action is machine executable, the Process Control is able to actually invoke the system command itself to perform the task. This gives rise to a unified user interface where the user can work exclusively with high level actions to Process Control File objects instead of having to remember the specific system level commands. Further, the objects have attributes associated therewith which are stored separate from the objects themselves. This allows for a single object to be accessed and used by multiple processes, both internal and external to the disclosed Process Control Framework. The object-oriented approach allows for access privileges for users, roles, and access rights for object classes to be defined and maintained by sending messages to retrieve or set the properties of these object classes. An object-oriented user paradigm for viewing and manipulating data and tools is reinforced with a true object-oriented system managing the data and tools.

Abstract: Many laser measurement methods for scanning the charge-carrier density or the potential distribution in the interior of a component (IC) in microelectronics are based on the so-called "backside probing" technique, in which the laser radiation (LA) is focused in the plane of the live components (SK) from the component rear with the aid of a conventional microscope objective. Since the irradiation is performed through the substrate (SU), a large spherical aberration is produced which limits the spatial resolution to approximately 2 to 4  mu m. In order to generate a sub- mu  probe in the substrate (SU) it is proposed to arrange on the polished rear (RS) of the component (IC) a lens consisting of a silicon base plate (GP, refractive index n1), a sphere (KU, refractive index n2 < n1, radius r2) situated in a recess of the baseplate (GP), and a silicon hemisphere (KS, refractive index n1, outside radius r1, inside radius r2). Given suitable selection of the refractive indices and of the radii, the lens and the substrate (SU) form an optical unit acting as a two-index Luneburg lens which focuses an incident parallel pencil (LA) at a point (LF) situated in the interior of the substrate (SU). …<IMAGE>…

Abstract: Hitherto, paper has been conveyed in apparatus such as printers by means of rollers or rollers and a push type pin tractor. A primary roller (11,21) has a slightly higher peripheral speed so as to impart tension on the paper (13). When reversing the direction of the conveyance, however, this tension can lead to paper jamming and a deterioration of printing accuracy. 
     The present invention employs rollers with resilient projections which, depending on the direction of rotation, alter the effective radius and hence the effective peripheral speed. This enables the primary roller (11,21) to maintain a slightly higher peripheral speed irrespective of the direction of conveyance.

Abstract: The distance between object and lens is obtained from the object's image. The present method inputs two observed images Is and Is′ with different blurs by changing either the position of the lens or the position of the image receiving plane with regard to the object by a minute distance Δz. It then filters the two observed images Is and Is′, thereby providing two output images Fs and Fs′. It calculates the distance a to the object by using the two output images Fs and Fs′ obtained by the filtering process using the relationship between the output image, the radius s of the blur and the distance a from the lens to the object.

Abstract: A high speed and memory efficient system and method for rendering Bézier curves. The system utilizes a hybrid forward differencing function representing the Bézier curve defined by the Bézier control points and renders the curve with a small number of straight line segments. The system renders the curve in a manner that results in the same Bézier control points that are calculated using the prior art recursive subdivision techniques and rejects line segment approximations that would not be derived from recursive subdivision. The system can start at either end of a Bézier curve and will render the same approximation. The method is readily implemented on a computer and is applicable to Bézier curves of any order.

Abstract: A method of forming piping at the end of a knitted fabric with a flat knitting machine having at least a pair of front and rear needle beds on each of which a plurality of knitting needles are arranged retractably. The method comprises holding loops of the knitted fabric with knitting needles on either the front or rear needle beds to empty knitting needles on the other needle bed. An elastic yarn is hooked with the specified knitting needles on the front and rear needle beds and a piping fabric part is knitted with the knitting needles not emptied, or with the knitting needles not emptied and the empty knitting needles on the other needle bed. The hooked yarn and the loops held with the knitting needles on the other needle bed are transferred to the needle bed on which loops at the end of this piping fabric part are held. An elastic yarn is supplied to the knitting needle placed at either right-edge or left-edge of the knitting needles holding the loops and a new loop is formed with the supplied yarn. The new loop is transferred to the adjacent knitting needle. The latter three steps are repeated to release the loops from the knitting needles. The method provides a knitted fabric having piping formed at its fabric end, comprising elastic yarns used at a joining part of an end of a piping fabric part and an end of the knitted fabric.

Abstract: A television signal determination circuit (10̸) is included in a color circuit. During a burst period, a color signal through a 90̸° phase-shifter (28) is subjected to frequency-phase conversion to be converted into a phase signal by an APF (14), the phase signal being applied to a phase-comparator (40̸) in which the phase signal and a color signal from a path (39) are compared with each other. An output of the phase-comparator (40̸) is applied to an LPF (42), and an output of the LPF (42) becomes a voltage signal having a level according to a phase difference of the both signals. Two voltage signals having different levels are alternately outputted at every 2H in a SECAM system, while only one voltage signal is outputted in other television systems. A rectangular-wave signal is produced from the voltage signal by a sampling/holding circuit (46), the rectangular-wave signal being phase-compared with a rectangular-wave signal delayed by 1H through a 1H delay circuit (48) in a phase-comparator (50̸). On the basis of a signal according to phase-comparison, and it is possible to determine a television system of the SECAM system or a PAL system.
