  • Publication number: 20170048728
    Abstract: The present invention relates to wireless networks and more specifically to systems and methods for selecting and implementing communication parameters used in a wireless network to optimize communication between access points and client devices. In one embodiment, the present invention includes a Wi-Fi coordinator device that receives client device information from client devices connected to an access point in a network. The Wi-Fi coordinator sends the client device information to a cloud intelligence engine which then combines the client device information with other client device information to identify the client devices in the network and their Wi-Fi capabilities and limitations. Using this information, the cloud intelligence devices determines the access point settings that would optimize the operation of the network.

  • Patent number: 8954900
    Abstract: A portion of a layout of a single layer of an integrated circuit is to be multi-patterned. The patterns are divided into first and second groups, to be patterned on the single layer by a first mask or a second mask. For each portion of each pattern, a spacing relationship is determined between that portion and any adjacent pattern on either or both sides. A processor computes a first capacitance (C), resistance (R), or resistance-capacitance (RC) cost of assigning the first group to the first mask and the second group to the second mask, and a second cost of assigning the first group to the second mask and the second group to the first mask, based on the spacing relationships. The first group is assigned to the first mask and the second group to the second mask if the first cost is lower than the second cost.
