Title: Telemetri som bruker "alltid pa" kommunikasjonssystem og fremgangsmate
Inventor: WHITFIELD ANDREW
IPC: H04M11/00
Filed: 2007-04-03
Abstract: Et telemetrisystem inkluderer i det minste en telemetrikommunikasjonsinnretning for å håndtere sikkerhetshendelsesinformasjon tilgjengelig for telemetrikommunikasjonsinnretninger. Systemet inkluderer også en sentral vertinnretning og et "alltid på"-nettverk, slik som Internettet, som kommunikasjonsmessig er koblet til telemetrikommunikasjonsinnretningen og den sentrale vertinnretningen, for kommunikasjoner mellom telemetrikommunikasjonsinnretningen og den sentrale vertinnretningen. Krypteringsnøkkelinformasjon blir utvekslet mellom den sentrale vertinnretningen og telemetrikommunikasjonsinnretningen, via en sikker vei, slik som et celletelefonkall mellom innretningene hvor identitet og autentisering kan bli sikret via kallinjeidentitetsinformasjon, eller annen sikker utveksling. Telemetriinformasjon blir kommunisert via telemetrikommunikasjonsinnretningen og den sentrale vertinnretningen over "alltid på"-nettverket i kryptert form i henhold til den bestemte krypteringsnøkkelen som er utvekslet. Den sentrale vertinnretningen kommuniserer også telemetriinformasjonen til en monitortjeneste over "alltid på"-nettverket og i kryptert format etter sikker utveksling av krypteringsnøkler mellom den sentrale vertinnretningen og monitortjenesten. Systemet kan også inkludere en back-up vei for kommunikasjon av telemetriinformasjon i det tilfellet at "alltid på"-nettverket ikke er tilgjengelig for kommunikasjoner.

Title: Fremgangsmate, system og datamaskinprogramprodukter for utforelse av struktursortering
Inventor: MCNEALY RICHARD C
IPC: G01B5/28
Filed: 2008-05-16
Abstract: Det er beskrevet en fremgangsmåte, system og datamaskinprogramprodukter for utførelse av stmktursortering/klassifisering. Fremgangsmåten innebærer at forhåndsdefinerte filterkriterier som kan brukes for å eliminere måledata som faller under en bestemt terskelverdi, anvendes på måleresultater fra en inspisert struktur. Fremgangsmåten innebærer videre at det identifiseres en basisdefektstørrelse knyttet til den inspiserte struktur. Basisdefektstørrelsen angir den største defekt som er i stand til å forbli upåvist under inspeksjonen. Fremgangsmåten innebærer også at det identifiseres toleransenivåer som gjelder de inspiserte strukturer og som brytes opp i faktorer som basisdefektstørrelse og attributter for den inspiserte struktur. Resultatet av å anvende de forhåndsdefinerte filterkriterier sammenlignes så med identifiserte toleransenivåer og en risiko for sprekking for den inspiserte struktur bestemmes på grunnlag av sammenligningen.
