Abstract: A system and method that enhance edges in images by detecting and correcting edges of the components of the image, such as the luma and the chroma components. The luma and the chroma edges may be corrected to align with one another. The luma edge detection may utilize a combination of the first and second derivatives of luma. The chroma edges may be sharpened by adjusting the saturation of the chroma components, without changing the hue. The luma edges may be corrected using a blend of peaking and enhancing the luma edges. The corrected chroma and luma components may be then debugged and the appropriate corrected components may be sent to display. Chroma/luma edge alignment may utilize a product of the luma first and second derivatives.

Abstract: A wired Local Area Network (wired LAN) and a plurality of Wireless Access Points (WAPs) coupled to a wired network infrastructure of the wired LAN service wireless packetized communications for a plurality of Wireless Local Area Network (WLAN) clients. A multi-layer switch of the wired LAN monitors packetized communications serviced by a WAP of the plurality of WAPs.

The RFIC then compares the measured received signal strength with a desired zero input signal strength value. If the measured received signal strength compares unfavorably with the desired zero input signal strength value (e.g.
