Title: A system for local context spilling for graph colouring register allocators
Inventor: MACLEOD ANDREW WILFRED
IPC: G06F9/45
Filed: 1997-05-22
Abstract: A  register  allocator  for  allocating  machine registers during compilation of a computer program.   The register  allocator  performs  the steps  of  building  an interference graph, reducing the graph using graph colouring techniques,  attempting  to  assign  colours  (i.e.  allocate machine registers to symbolic registers), and generating spill code.  The spill code is generated by a local context spiller which processes a basic block on an instruction by instruction basis.   The local context spiller attempts to allocate a machine register which is free in the basic block.   If the basic block does not have any free machine registers,  the local context spiller looks ahead to select a machine register for spilling.  The register allocator improves the performance of a compiler by limiting the rebuilding of the interference graph and the number of the graph reduction operations.

Abstract: L'invention concerne les procédés qui permettent de certifier des reproductions de documents, en particulier des télécopies. Elle consiste à traiter l'image d'une zone réservée (103) du document original en la comprimant et en y rajoutant des données d'identification. A partir du signal obtenu après traitement, on élabore un ensemble de codes-barres qui est imprimé dans un espace réservé à un sceau d'identification. La hauteur des colonnes de ces codes-barres est égale à plusieurs lignes d'analyse et les codes-barres sont imprimés sous la forme de plusieurs trames successives. De cette manière, on arrive à relire le code-barre en dépit des distorsions provenant tant de la transmission que de l'impression puis de la lecture.

Abstract: A microporous polyolefin composite membrane, preferably for use as a battery separator, comprising a microporous polyolefin membrane and a polyolefin nonwoven fabric laminated on at least one surface of the microporous polyolefin membrane. The composite membrane has a thickness of 25 to 200 µm, a porosity of 30 to 70%, an air permeability of 100 to 2000 sec/100cc and a surface opening area ratio of 50 to 90% on at least one outer surface thereof. The microporous polyolefin membrane comprises a matrix polyolefin component which is a polyolefin having a weight average molecular weight of 5 × 10 5 or more or a polyolefin mixture containing the polyolefin having a weight average molecular weight of 5 × 10 5 or more, and has a porosity of 30 to 95%, an air permeability of 100 to 2000 sec/100cc, an average open pore diameter of 0.001 to 1 µm and a tensile strength at break of 500 kg/cm2 or more. The microporous polyolefin membrane may further comprise a shutdown polymer component to shut down the pores, thereby making the composite membrane impermeable. The polyolefin nonwoven fabric comprises fine fibers and has an air permeability of 0.1 to 100 sec/100cc and a basis weight of 5 to 50 g/m2. The polyolefin nonwoven fabric prevents the composite membrane from melting down at a low temperature thereby preventing the short-circuit between the electrodes.

Title: A spectrometric micro-sensor/transducer and procedure for interpretation of spectrometric data
Inventor: MORAWSKI ROMAN Z
IPC: G01J3/18
Filed: 1997-08-08
Abstract: A procedure for interpretation of spectrometric data, useful in all branches of spectroscopy, is disclosed. This procedure is composed of three sub-procedures whose functions are: calibration of the spectrometer, reconstruction of the spectrum of the sample under study, and estimation of the parameters of this spectrum. The sub-procedure for calibration of the spectrometer is comprising an organized set of methods for identification of a numerical relation between the measurement results produced by this spectrometer and established measurement standards of spectrum. The sub-procedure of reconstruction is comprising an organized set of methods for numerical reconstruction of the spectrum of the sample under study, i.e. for partial elimination of the effects of noise and blur corrupting the spectrometric data. The sub-procedure of spectrum parameter estimation is comprising an organized set of methods for numerical estimation of the positions and magnitudes of peaks the spectrum of the sample is composed of. The invention also provides a spectrometric micro-sensor/transducer, for light spectrum measurement, useful for applications in different spectrum-measurement-based instrumentation, especially in the miniaturized intelligent spectrometric probes for in situ measurements, are disclosed. In order to circumvent the difficulties with the integration of the optical functions using the semiconductor-based integration technologies, the basic idea of the proposed method for providing a spectrometric micro-sensor/transducer, is based on transferring the problem of the accuracy of measurement from the domain of optical analog signal processing to the domain of electrical digital signal processing - much easier to integration. According to the invention, the new method consist of designing a simple optical device, a signal discretization block and a specialized digital signal processor and then to combine them in one functionally fused entity: an intelligent integrated spectrometric sensor/transducer (IISS/T). The designed (IISS/T) allows for obtaining the quality result of measurement: an estimate of the measured light spectrum or its parameters defined by the user. This fusion of the functional blocks enables the designer of IISS/T to profit of the best of both parts: optical and electrical. The proposed method of providing a spectrometric micro-sensor/transducer is more efficient then existing methods based on the sophisticated optical analog processing because it is free of troubles characteristic for this type of processing. The ISS/T is a low cost, flexible, quality spectrometric sensor/transducer which may be easily adapted to very diversified applications via customizing of the specialized digital processor. When manufactured as a miniature compact package it can be made robust to mechanical, electromagnetic, chemical and biological influences (distortions).

Inventor: ORTLOFF CHARLES R
IPC: F16L27/08
Filed: 1997-09-19
Abstract: In combination with a dual elbow swivel joint having a female elbow member rotationally coupled to a male elbow member, the invention comprises an orientation device having an angle marker located on one elbow member and an indicator mark located on the other elbow member.    The angle marker contains a number of angle markings located at predetermined angles measured from the central axis of the elbow member.    The indicator mark is placed on the other elbow member in a location such that, when aligned with an angle marking, the elbow members are in a predetermined angular orientation relative to each other.  The angle markings on the angle marker each have a length which is related to the amount of wear that has been found to occur in the dual elbow swivel joint when the female and male members are oriented at that particular angle.    Thus, the orientation device enables an operator to orient the female and male elbow members at an angle at which the dual elbow swivel joint will experience the least amount of wear.

Abstract: X-ray images are displayed at both high-resolution and high illumination with annotation superimposed in registration therewith to point out suspected abnormalities identified through a process in which the x-ray images are digitized and the digitized information is subjected to feature extraction processing. For example, the x-ray images are displayed at both high-resolution and high illumination in the form of x-ray film images displayed on a light box while the annotation information is selectively superimposed on the same image by a separate imaging system co-acting with the light box. In this manner, the radiologist can view either the x-ray film alone, in the conventional manner, or the same x-ray film, at the same position and at the same high resolution and at the same or substantially the same illumination level but with annotation information superimposed and in registration therewith. In addition, alternative ways are disclosed for displaying the high resolution x-ray image and for selectively superimposing the annotation information thereon.
