Abstract: L'invention concerne un procédé de collage d'une puce de circuit (2) qui présente au moins deux plages de connexion (8, 10) sur une première surface principale. Ce procédé consiste d'abord à appliquer la puce de circuit (2) par une deuxième surface principale opposée à la première surface principale, sur une surface principale d'un substrat (4) de telle façon que la puce (2) soit, de toute son épaisseur, en saillie sur la surface du substrat (4). Ensuite, une métallisation structurée est appliquée sur la première surface principale de la puce de circuit (2) et sur la surface du substrat (4) par un procédé de sérigraphie ou un procédé d'emboutissage afin de relier les plages de connexion (8, 10) de la puce de circuit (2) à une structure conductrice (16) placée sur la surface principale du substrat (4). En variante, on utilise le procédé de sérigraphie ou d'emboutissage pour appliquer une métallisation structurée sur la première surface principale de la puce de circuit (2) et la surface du substrat (4) pour produire une structure conductrice périphérique qui soit reliée aux plages de connexion de la puce de circuit sur la surface principale du substrat (4) et sur la première surface principale de la puce de circuit (2).

Abstract: In-mold labelled, blow-molded articles formed from high density polyethylene, the labels being formed from biaxially oriented polypropylene based films having a shrinkage of at least 4% in both the machine and transverse directions as measured by the OPMA shrink test in which the film is suspended in an oven at 130° C. for a period of 10 minutes. The use of films with the specified shrinkage enables blistering and "orange peel" effects to be avoided when the blow-molding is carried out.

Abstract: Systems and methods are described for improved yield and line width performance for liquid polymers and other materials. A method for minimizing precipitation of developing reactant by lowering a sudden change in pH includes: developing at least a portion of a polymer layer on a substrate with an initial charge of a developer fluid; then rinsing the polymer with an additional charge of the developer fluid so as to controllably minimize a subsequent sudden change in pH; and then rinsing the polymer with a charge of another fluid. An apparatus for minimizing fluid impingement force on a polymer layer to be developed on a substrate includes: a nozzle including: a developer manifold adapted to supply a developer fluid; a plurality of developer fluid conduits coupled to the developer manifold; a rinse manifold adapted to supply a rinse fluid; and a plurality of rinse fluid conduits coupled to the developer manifold. The developer manifold and the rinse manifold can be staggered so as to reduce an external width of the nozzle compared to a nominal external width of the nozzle achievable without either intersecting the fluid manifold and the another manifold or staggering the fluid manifold and the another manifold. The systems and methods provide advantages including improve yield via reduced process-induced defect and partial counts, and improved critical dimension (CD) control capability.

Abstract: A plurality of computer nodes communicates using seemingly random IP source and destination addresses and (optionally) a seemingly random discriminator field. Data packets matching criteria defined by a moving window of valid addresses are accepted for further processing, while those that do not meet the criteria are rejected. In addition to "hopping" of IP addresses and discriminator fields, hardware addresses such as Media Access Control addresses can be hopped. The hopped addresses are generated by random number generators having non-repeating sequence lengths that are easily determined a-priori, which can quickly jump ahead in sequence by an arbitrary number of random steps and which have the property that future random numbers are difficult to guess without knowing the random number generator's parameters. Synchronisation techniques can be used to re-establish synchronization between sending and receiving nodes. These techniques include a self-synchronization technique in which a sync field is transmitted as part of each packet, and a "checkpoint" scheme by which transmitting and receiving nodes can advance to a known point in their hopping schemes. A fast-packet reject technique based on the use of presence vectors is also described.

Abstract: Oppfinnelsen gjelder en fremgangsmåte for automatisk analyse av signaler som oppfanges av en eller flere opptakene for elastiske eller akustiske bølger med det formål å automatisk tidsfeste på signalene med høy presisjon minst ett betydningsfullt tidspunkt, slik som tidspunktet for den første ankomst på hver opptaker (tj) og/eller sluttidspunktet (tf) for disse signaler. Fremgangsmåten omfatter i det vesentlige bestemmelse av den pseudoperiode som tilsvarer den inverse av den dominerende frekvens i frekvensspekteret for hvert oppfanget signal, koding av hvert oppfanget signal slik at det dannes et binært kodet signal i forhold til en første terskelverdi som avhenger av det oppfangede signal, dannelse for hver av disse et integralsignal ved å stakke det binært kodede signal på et glidende vindu med det formål å fastlegge en andre terskelverdi, samt posisjonsinnstilling av det betydningsfulle tidspunkt som søkes (tj, tf) på hvert oppfanget signal i forhold til et tidspunkt hvor det tilsvarende signal når denne andre terskelverdi. Denne fremgangsmåte er selvtilpassende på grunn av at den anvender parametere (særlig terskelverdier) som avhenger av egenskapene av det mottatte signal. Den kan særlig anvendes for (aktiv eller passiv) seismisk overvåking av underjordiske reservoarer, generelt innenfor det akustiske felt, i sonarutstyr, etc.

Abstract: A preferred novel circulating sub includes an electric motor, hydraulic intensifier, connecting rod, valve sleeve, valve plug, and angled nozzles. Upon activation of the circulating sub the electric motor drives the valve sleeve over the valve plug, causing a flow of drilling fluid to exit the angled nozzles. Upon deactivation of the circulating sub, the electric motor removes the valve sleeve from the valve plug, allowing the flow of drilling fluid to once again flow to the drill bit. Because the electric motor is reversible, the circulating sub can be repeatedly activated and deactivated.

Abstract: Et søkesystem med en søkemotor benytter et brukersøkespørsmål på en indeks over dokumenter lagret i et dokumentmagasin og returnerer et resultatsett av overensstemmende dokumenter til en bruker. For å utføre aksess, søking og gjenfinning av dokumenter lagret i dokumentmagasiner mer effektivt, partisjoneres enten dokumentmagasinet eller en indeks over dette eller begge i en eller flere dimensjoner, og en partisjon konfigureres i en spesifikk dimensjon i henhold til to eller flere dokumentattributtverdier valgt fra en og samme attributtkategori. Dette gjør det mulig for en søkeapplikasjon å aksessere vesentlig mindre data for å bestemme et søkeresultat og vil i høy grad forbedre effektiviteten til bedriftssøkesystemer.

II and III and their derivatives are analogous to prostaglandin E, prostaglandin F and prostaglandin A in their bilogical activity, but are much more specific in action. As the present compounds have a narrower biological spectrum, their use is generally attended by a lesser degree of undesired side actions than for the natural prostaglandins. In addition, some of the synthetic compounds show a higher biological response than the natural prostaglandins in a specific area.
