Abstract:

An efficient coding scheme with higher audio bandwidth and/or better audio quality at lower bitrates, wherein the scheme eliminates long-term and short-term frequency domain correlation in a signal via frequency domain predictors. The coding scheme compresses information consisting of coded low frequency components as well as a parametric representation for the high frequency components based on a non-linear model. Additionally, by working on the frequency domain representations of the signal (such as the MDCT representation which is naturally available to a PAC encoder and decoder), low pass and high pass signal components are easily obtained by windowing the appropriate ranges of frequencies in the signal. Furthermore, the power functions of the signal are replaced by corresponding convolution functions of the same order.

International Classification:

G05F 100

US Classification:

315307

Abstract:

A compact fluorescent lamp and an electronic ballast therefor are mounted on a three-terminal base which can be fitted into a three-way-switched standard AC lamp socket, so as to be responsive to the three powered switch positions of the socket for generating three light output levels. The ballast includes an AC-to-DC conversion circuit which supplies a lamp driver including a DC-to-AC conversion circuit, an oscillatory circuit and a resonant circuit. In one embodiment the AC-to-DC conversion circuit includes a full bridge rectifier and a voltage doubler producing two operating voltage levels for the lamp driver and two frequency control voltage levels for the oscillator, the ballast generating three light output levels by using two operating voltages and two operating frequencies. One of the lamp filaments is connected in series with the supply circuit for the oscillator so that the oscillator is inoperative when the lamp is disconnected or its filament burns out, and there is a feedback circuit from the resonant circuit to the oscillator supply for stabilizing its operating frequency. In another embodiment the AC-to-DC conversion circuit includes a half bridge rectifier and two voltage doublers for producing three operating voltages for the lamp driver to generate the three light output levels.

Abstract:

An article that includes: a substrate having a glass, glass-ceramic or a ceramic composition and comprising a primary surface; and a protective film disposed on the primary surface. The protective film comprises a thickness of greater than 1.5 microns and a maximum hardness of greater than 15 GPa at a depth of 500 nanometers, as measured on the film disposed on the substrate. Further, the protective film comprises a metal oxynitride that is graded such that an oxygen concentration in the film varies by 1.3 or more atomic %. In addition, the substrate comprises an elastic modulus less than an elastic modulus of the film.
