Title: Signalkomparator.
Inventor: SEVENHANS JOANNES MATHILDA JOS
IPC: G05F3/24
Filed: 1989-06-16
Abstract: Foreliggende oppfinnelse angår en to-ti 1 standskrets (ST), en strømkilde (BS), en bi stabil anordning (FF) og en inngangskrets (IO som alle er utformet for å kunne utgjøre en s1gnalkomparator. To-tHstandkretsen (ST) er en Schmitt-trigger som omfatter strømstyr1ngsanord-ninger (N17, P13; N18, P14) for å tilveiebringe en strøm for å balansere avvikene i konstruksjonsparametrene til transistorene, slik at driftskarakteri-stikkene for disse anordninger forblir identiske fra én prosess til en annen. Strømkilden (BS) gjør bruk av en strømspei1 ende konfigurasjon og styres via en gren som er koplet mellom spenningsti1 førsel skiemmene (VDD; VSS).To (N2, N3) av de fire (NI til N4) seriekoplede transistorene som utgjør en del av denne grenen har en større bredde-til-lengde W/L kanal parameter, slik at identiske strømkilder (BS) kan fremstil-les i stor skala, fordi strømmen (15; II) som tilføres av den sistnevnte da blir uavhengig av terskel spenningene til de benyttede transistorer. Den bistabile anordning (FF) er en flipp-flopp krets som har di f ferensiel 1e samlede inngangs-og utgangsklemmer (Tl; T2) og benyttes til å assosiere inngangskretsen (IC) som har en di fferensiell, analog utgang og toti 1standskretsen (ST) som har en di fferensiel1 digital inngang. Denne bistabile anordning har sine inngangs--/utgangs-klemmer shuntet av en MOS-transistor (NI4) ved hvert høye klokke-signal (CU), og derfor vil den felles spenning på dens klemmer ligge midtveis mellom ti 1 førselsspenningene, slik at når tilstanden forandres, så vil disse spenninger bare måtte variere med halvdelen i stedet for med full spen-ni ngsdi ff eranse . Dette tillater en hurtigere svitsjing av den bistabile anordning. Inngangskretsen (IC) er en høyfrekvent, differensiell inngangs-(11;. 12(/dobbel avsiuttet utgangs-(Tl; T2)krets.

Filed: 1998-06-23
Abstract: In a method for coding an audio signal digitized at a low sampling rate to obtain time domain audio samples. A frequency domain representation of the time domain audio samples is produced. The frequency domain representation includes successive frequency lines. These frequency lines are grouped into a plurality of scale factor bands. The successive frequency lines in a scale factor band are coded with the same scale factor. A plurality of regions is formed by grouping the scale factor bands, wherein successive scale factor bands form a region within which all the scale factors are coded with the same number of bits, which is determined according to the largest scale factor of the region. The scale factors assigned to scale factor bands within the highest region that includes the higher frequency successive frequency lines are set to zero. The frequency lines in the highest region are coded using the zero-valued scale factors that correspond to a multiplication factor of 1. The scale factors for the highest region, however, are not coded. Thus, the bits that would be required for coding these zero-valued scale factors are saved and can be used for a finer quantization of the rest of the spectrum. Additionally, this coding method when applied to ISO/IEC 13818-3 as a low sampling rate modification thereof only requires minimal changes with respect to this Standard.

Abstract: An electrical surge arrester is manufactured by securing a stack of metal oxide varistor blocks between end terminations by passing a rod through through-holes in the varistor blocks and securing the ends of the rod to the end terminations. The through-holes are larger than the rod cross-section and a silicone rubber material is injected into the void which otherwise would exist between the rod and the interior surfaces of the through-holes in the varistor blocks. The silicone rubber material is also moulded around the exterior of the stacked varistor blocks and forms a shedded external housing for the arrester. The silicone rubber coatings on the varistor block internal and external surfaces effects a passivation function and means that the passivation coatings normally provided on the surfaces of varistor blocks by their manufacturers at significant cost can be omitted.
