  • Publication number: 20240130635
    Abstract: A device is provided for overcoming freezing of gait. Suitably, the device includes a sleeve sized and shaped to be worn on a leg of a human subject, an array of electrodes carried by the sleeve and positioned to make surface contact with a skin of the leg when the sleeve is worn on by the human subject, and a controller in communication with the array of electrodes. The controller is operative to receive muscle activity data from the array of electrodes indicative of muscle activity in the leg, identify an onset of a freezing of gait episode based on the received muscle activity data, and trigger energization of one or more targeted electrodes in response to identification of the onset of the freezing of gait episode to mitigate against the freezing of gait episode.

  • Patent number: 9848459
    Abstract: A method for establishing an unmanned aerial vehicle (UAV) network among a plurality of UAVs that is programmed to communicate packet data, wherein the plurality of UAVs comprises a first UAV and creating a first wireless connection between the first UAV of the plurality of UAVs and a second UAV. The method includes receiving a first signal indicating that the second UAV has been added to the plurality of UAVs and transmitting a second signal to the second UAV that causes the second UAV to generate a wireless coverage area that extends a wireless range of the UAV network. The method includes calculating a plurality of link cost values for one or more wireless connections to or from each particular UAV to one or more other UAVs in the plurality of UAVs; and determining whether to realign the plurality of UAVs based on the plurality of link cost values.

  • Publication number: 20070142030
    Abstract: Security vulnerability assessment for wireless networks is provided. Systems and methods for security vulnerability assessment simulate an attack upon the wireless network, capture the response from the wireless network, and identify a vulnerability associated with the wireless network after analyzing the response from the wireless network.
