  • Publication number: 20070202830
    Abstract: The present invention provides a spurious tone suppressor for use with a power supply system. In one embodiment, the spurious tone suppressor includes an error signal generator configured to provide a spur error signal proportional to a spur signal associated with the power supply system. Additionally, the spurious tone suppressor also includes an adaptive spur cancellation engine coupled to the error signal generator and configured to adaptively process the spur error signal and generate a corresponding anti-spur signal that is injected into the power supply system to suppress the spur signal.

  • Patent number: 7262894
    Abstract: A mirror display system comprising a multiplicity of scan lines that are combined to generate an image. The multiplicity of scan lines are orthogonally positioned in response to a slow speed cyclic drive signal (for example, sinusoidal or repetitive triangular shape). To increase the brightness of the display, and unlike a typical raster scan display, scan lines are generated during both the positive going portion and the negative going portion of the cyclic drive signal.

  • Patent number: 7262716
    Abstract: An asynchronous sample rate converter interpolates and filters a digital audio input signal to produce a filtered, up-sampled first signal. A FIFO memory receives the first signal and stores samples thereof at locations determined by a write address and presents stored samples from locations determined by a read address. The presented samples are passed through an interpolation and resampling circuit to produce a continuous-time signal which is re-sampled to produce a signal that is up-sampled relative to a desired output. That signal then is filtered and down-sampled to produce the output signal. Sample rate estimating circuitry computes a difference signal representative of a time at which a data sample of the audio input signal is received and a time at which a corresponding audio output sample is required, and address generation circuitry generates the read and write addresses.

  • Patent number: 7262900
    Abstract: As robust hinge post structure for use with torsional hinged devices such as micromirrors and method of manufacturing is disclosed. The fabrication process uses a protective layer such as BARC on the bottom of the aperture used to form the hinge post structure to protect an oxide layer during an etching step. The oxide layer, in turn protects the metal layer at the bottom of the aperture. Therefore, the metal layer, the oxide layer, and the protective layer prevent the erosion and/or pitting of the bottom electrode during a cleaning process, and provide additional support to the structure.

  • Patent number: 7262658
    Abstract: A Class-D amplifier system may include an input stage that includes an Nth order filter, where N>1. The input stage filters an input signal to provide a filtered output signal, an input of the input stage being configured to receive the input signal as a digital pulse-width-modulated (PWM) signal. A comparator provides a quantized output signal based on the filtered output signal. An output stage is connected between a first voltage rail and a second voltage rail. The output stage provides a switching output signal at an output that varies between the first voltage rail and the second voltage rail based on the quantized output signal. A feedback path connects the output of the output stage with the input of the input stage, such that the Nth order filter compensates for variations in at least one of the first voltage rail and the second voltage rail.

  • Patent number: 7262817
    Abstract: In order to minimize light diffraction along the direction of switching and more particularly light diffraction into the acceptance cone of the collection optics, in the present invention, micromirrors are provided which are not rectangular. Also, in order to minimize the cost of the illumination optics and the size of the display unit of the present invention, the light source is placed orthogonal to the rows (or columns) of the array, and/or the light source is placed orthogonal to a side of the frame defining the active area of the array. The incident light beam, though orthogonal to the sides of the active area, is not however, orthogonal to any substantial portion of sides of the individual micromirrors in the array. Orthogonal sides cause incident light to diffract along the direction of micromirror switching, and result in light ‘leakage’ into the ‘on’ state even if the micromirror is in the ‘off’ state. This light diffraction decreases the contrast ratio of the micromirror.
