Patent number: 11596346Abstract: A technology is described for determining an intended movement from neuromuscular signals. An example method (800) includes receiving electromyography (EMG) data corresponding to single-ended channels of an electrode array (810), where EMG signals are detected by electrodes comprising the single-ended channels of the electrode array and the EMG signals are converted to the EMG data. Determining differential channel pairs for the single-ended channels of the electrode array (820) and extracting feature data from the EMG data of the differential channel pairs (830). Thereafter a feature data set is selected from the feature data of the differential channel pairs (840) and the feature data set is input to a decode model configured to correlate the feature data set to an intended movement (850). Decode output is received from the decode model indicating the intended movement (860) and the decode output is provided to a device (870).Type: GrantFiled: August 1, 2017Date of Patent: March 7, 2023Assignee: University of Utah Research FoundationInventors: Suzanne Wendelken, Tyler Davis, David Page, David Kluger, David Warren, Gregory Clark, Christopher Duncan, Jacob Nieveen

Patent number: 10549099Abstract: A technology is described for an electronic peripheral nerve stimulation system. The electronic nerve stimulation system can include a stimulation device and an electrode array. The stimulation device can be operable to generate a high-frequency alternating current. The electrode array can be operable to apply the high-frequency alternating current received from the stimulation device to selected subpopulations of peripheral nerve fibers within a peripheral nerve to block transmission of neural signals along the selected subpopulations of peripheral nerve fibers within the peripheral nerve.Type: GrantFiled: May 1, 2017Date of Patent: February 4, 2020Assignee: University of Utah Research FoundationInventors: David Kluger, Christopher Duncan, David Page, Gregory Clark, Tyler Davis, Suzanne Wendelken

Patent number: 9973543Abstract: Methods and systems for switching between computing devices during an online meeting are described herein. A collaboration server may receive a token from a first computing device connected to an online meeting hosted by the collaboration server. The collaboration server may receive another token from a second computing device and determine whether the received tokens match. If so, the collaboration server may establish an association between the second computing device and the meeting participant attending the online meeting via the first computing device. The collaboration server may accept a request from the second computing device to join the online meeting thus allowing the meeting participant to continue the online meeting from the second computing device.Type: GrantFiled: October 13, 2014Date of Patent: May 15, 2018Assignee: GetGo, Inc.Inventors: Gaurav Chitroda, Paul FitzGerald, Christopher Duncan, Carey Caulfield
