  • Publication number: 20130169324
    Abstract: A fully integrated ramp generator circuit includes a first current generator that sources current to first capacitor through a first transistor that is gate controlled by the complement of a periodic signal. The ramping voltage stored on the first capacitor is buffered to an output node as a ramp output signal. A second transistor couples the output node to the first current generator and is gate controlled by the periodic signal. The periodic signal is generated at the output of a flip-flop that receives an input clock signal and reset signal. The reset signal is generated by a comparator circuit operable to compare the voltage on a second capacitor to a reference. The second capacitor is charged by a second current source and discharged by a third transistor that is gate controlled by the periodic signal.

If the drive circuit is a high side driver, the intermediate voltage node receives an intermediate voltage Vmed set below the high supply voltage and that mees the following conditions: a) Vmed<=V1 and b) Vhigh?Vmed<=V2. The circuit may be configured as a push pull driver by coupling a high side driver and low side driver in series.

  • Publication number: 20130169188
    Abstract: A bidirectional voltage differentiator circuit comprises start-up circuitry, sensing circuitry, and output circuitry coupled to logic circuitry. The start-up circuitry acts to start-up the sensing circuitry when the circuit is powered on, and accelerates the response of the sensing circuitry thereafter. The sensing circuitry senses variation in an input voltage applied to an input node. Responsive to the voltage variation sensed by the sensing circuitry, the output circuitry produces a state change at a first or second output node. The logic circuitry receives the states of the output nodes and produces a logic output signal to indicate the occurrence of the variation sensed in the input voltage. The voltage sensing circuit is operable to sense variation of the input voltage regardless of whether the voltage is rising or falling and without regard to the DC value of the input voltage.

  • Publication number: 20130163836
    Abstract: The mass of an object may be estimated based on intersection points of a representation of a surface in an image space with cubes defining the image space, the surface representing a surface of an object. The representation may be, for example, based on marching cubes. The mass may be estimated by estimating a mass contribution of a first set of cubes contained entirely within the representation of the surface, estimating a mass contribution of a second set of cubes having intersection points with the representation of the surface, and summing the estimated mass contribution of the first set of cubes and the estimated mass contribution of the second set of cubes. The object may be segmented from other portions of an image prior to estimating the mass of the object.

  • Publication number: 20130162871
    Abstract: Image defects in digital images are easily detectable by the human eye but may be difficult to detect in a computer-implemented fashion. In an embodiment of a digital-image-acquisition device, defects are removed on the CFA domain before color interpolation takes place. In order to allow cancellation of couplets of defective pixels, a two pass embodiment is presented. Such embodiment presents methods and systems that can remove both couplets and singlets without damaging the image. The system includes a ring corrector that detects a defect in the ring of pixels that surround a central pixel, a singlet corrector that detects and corrects the central pixel and removes a couplet if the ring corrector is activated, whereas if the ring corrector is switched off, the singlet corrector only removes singlets, and a peak-and-valley detector that avoids overcorrection by avoiding correcting signal peaks or valleys in case of spikes or drops in signal.
