  • Patent number: 9740918
    Abstract: Subject matter disclosed herein relates to arrangements and techniques that provide for identifying objects within an image such as the face position of a user of a portable electronic device. An application specific integrated circuit (ASIC) is configured to locate objects within images. The ASIC includes an image node configured to process an image and a search node configured to search the image for an object in the image. The ASIC also includes an ensemble node configured to confirm the presence of the object in the image. The ensemble node progressively compares, using computational engines that include accumulators, the pixel values of a template with pixel values of a region of interest in the image to create comparison result values.

  • Patent number: 9500535
    Abstract: Each of one or more temperature sensors of a computing system can measure and provide a temperature value (e.g., provide temperature data) to the system. In some embodiments, the system can apply an offset value, a time-based filter, and a weighting factor to each temperature value received from the one or more temperature sensors of the system. Based, at least in part, on the offsetting, filtering, and/or weighting, the computing system can determine (e.g., calculate, estimate, predict, etc.,) a temperature value representative of an enclosure temperature of the system. In some embodiments, based on the determined temperature value that is representative of the enclosure temperature, the computing system can perform appropriate subsequent processing in accordance with thermal management of the system.

  • Patent number: 8471932
    Abstract: Systems and methods are disclosed for applying spatial filtering to raw image data. For example, a spatial filter may identify an n x n block of pixels from an image frame. The spatial filter has filter taps, each corresponding to one of the pixels of the n x n block. Pixel difference values between the input pixel and each of the neighboring pixels in the n x n block may be determined. Attenuation factors may be determined based on the pixel differences and brightness of the input pixel. Applying the attenuation factors to their respective filtering taps may produce attenuated filtering coefficients that are used to obtain filtered pixel values. By normalizing the sum of the filtered pixel values using the sum of the attenuated filtering coefficients, a spatially filtered output value corresponding to the current input pixel (e.g., located at the center of the n x n block) may be determined.

  • Publication number: 20120081553
    Abstract: Systems and methods are disclosed for applying spatial filtering to raw image data. In one embodiment, a spatial filter may identify an n×n block of pixels from the current image frame, the n×n block including a plurality of neighboring pixels being centered about a current input pixel and being of the same color component as the current input pixel. The spatial filter may include a plurality of filter taps, with one filter tap corresponding to each of the pixels within the n×n block. A set of filtering coefficients for each filter tap, which may be based on a Gaussian function, may be determined. A pixel difference value between the current input pixel and each of the plurality of neighboring pixels in the n×n block are determined, and the pixel differences may be used to determine an attenuation factor for each filter tap.

  • Patent number: 6781342
    Abstract: A three phase motor starting system is provided to reduce the in-rush current to the motor in order to obtain a soft start of the motor. The soft start of the motor equates to reduced impact forces on motor parts and device components connected to the motor during startup of the motor, especially a startup resulting from a reversal of the direction of rotation of the motor. The system uses an impedance load in series with the motor windings of the motor to reduce the in-rush current to the motor windings, which results in a reduced acceleration of the motor shaft and a soft start to the motor. The impedance loads used by the system can be a resistive load, a capacitive load or an inductive load, depending on the type of impedance load that is desired for the soft start of the motor.
