  • Patent number: 9710926
    Abstract: A system and method for processing an image of a retail shelf area. According to one aspect, a portion of an image that depicts the retail shelf area at an angled and depthwise perspective is determined to depict shelves. The image can be modified so that the portion of the image determined to depict shelves is substantially parallel to a predefined horizontal reference frame. Products can then be detected in the remainder portion of the image, separate from the portion of the image determined to depict shelves. An applicable planogram can be used to generate compliance information based on the detected products and the determined portion of the image depicting shelves.

  • Patent number: 9685931
    Abstract: Certain aspects of the present disclosure provide circuits for generating high accuracy millimeter wave or radio frequency (RF) wideband in-phase (I) and quadrature (Q) oscillating signals having acceptable amplitude and phase mismatch over process, voltage, and temperature (PVT) variations with reduced cost, area, and power consumption. In one example apparatus, a polyphase filter having a first stage and a second stage is provided. Each stage comprises resistive elements and capacitive elements. Certain aspects of the present disclosure provide for intentional resistive and/or capacitive value mismatch between the resistive or capacitive values of one or multiple stages such that the phase mismatch between the resulting I and Q signals may be reduced without degrading the amplitude mismatch. Certain aspects of the present disclosure provide for replacing the resistive elements in at least one stage with transistors operating in the triode region, where the on-resistance is controlled by a feedback network.
