  • Patent number: 8878903
    Abstract: The disclosure relates to a method for reconstruction of a three-dimensional image of an object. A first image is acquired of the object lit by a luminous flux having, in a region including the object, a luminous intensity dependant on the distance, with a light source emitting the luminous flux. A second image is acquired of the object lit by a luminous flux having, in a region including the object, a constant luminous intensity. For each pixel of a three-dimensional image, a relative distance of a point of the object is determined as a function of the intensity of a pixel corresponding to the point of the object in each of the acquired images.

  • Patent number: 8613038
    Abstract: An embodiment of the present invention discloses a system and method for decoding multiple independent encoded audio streams using a single decoder. The system includes one or more parsers, a preprocessor, an audio decoder, and a renderer. The parser extracts individual audio frames from each input audio stream. The preprocessor combines the outputs of all parsers into a single audio frame stream and enables sharing of the audio decoder among multiple independent encoded audio streams. The audio decoder decodes the single audio frame stream and provides a single decoded audio stream. And the renderer renders the individual reconstructed audio streams from the single decoded audio stream.

  • Patent number: 8493171
    Abstract: A trimmable resistor for use in an integrated circuit is trimmed using a heater. The heater is selectively coupled to a voltage source. The application of voltage to the heater causes the heater temperature to increase and produce heat. The heat permeates through a thermal separator to the trimmable resistor. The resistance of the trimmable resistor is permanently increased or decreased when the temperature of the resistor is increased to a value within a particular range of temperatures.

  • Patent number: 8477876
    Abstract: A method for searching a digital transmission having unknown carrier and symbol frequencies in a modulated reception signal, includes performing successive trials of several carrier and symbol frequencies, using decreasing values of the symbol frequency, demodulating the reception signal with the tried carrier frequency, filtering the demodulated signal in a band having a width corresponding to the currently tried symbol frequency, and producing samples of the filtered signal. For each currently tried symbol frequency, forming a complex indicator having a real component and an imaginary component established from the successive samples of the filtered signal such that they have cyclostationary properties and that one of the components tends to cancel when the other component tends towards a relative maximum, building the spectrum of the variation of the complex indicator, searching for a singular spike in the spectrum, and determining the real symbol frequency from the frequency of the spike.
