Patent number: 11963721Abstract: The present disclosure relates to a method and a system for quantifying a biomarker of a biological tissue. Two spectral sub-intervals are determined from a plurality of images of the tissue acquired at discrete wavelengths within a main wavelength interval using an imaging sensor in a manner such that the combination of the image data in the at least two spectral sub-intervals are correlated with a clinical variable of interest. The tissue is illuminated using one or more light sources with wavelengths within the at least two spectral sub-intervals. A measurement is of the light reflected by the tissue is acquired using an imaging sensor; and a measure of the biomarker of the tissue is calculated using the acquired measurement. The main wavelength interval is broader than each of the at least two spectral sub-intervals and at least one spectral confounder causing a spectral variability of the acquired image is present in the tissue.Type: GrantFiled: January 11, 2019Date of Patent: April 23, 2024Assignee: Centre For Eye Research Australia LimitedInventors: Xavier Hadoux, Flora Hui, Peter Van Wijngaarden, Jonathan Guy Crowston

Patent number: 10038625Abstract: In one embodiment, a device in a network detects a bidirectional traffic flow along a primary path in the network. The device determines that a self-interference condition exists along the primary path. The device selects an alternate path in the network. The device causes the traffic flow to use the primary path for packets of the traffic flow sent in a first direction and to use the alternate path for packets of the traffic flow send in a second direction that is opposite that of the first direction.Type: GrantFiled: November 21, 2014Date of Patent: July 31, 2018Assignee: Cisco Technology, Inc.Inventors: Jonathan Hui, Jean-Philippe Vasseur, Wei Hong

Patent number: 9955456Abstract: In one embodiment, a device in a network determines a first channel hopping schedule for the device to receive unicast communications from one or more neighbors of the device. The first channel hopping schedule differs from channel hopping schedules used by the one or more neighbors to receive unicast communications. The device determines a second channel hopping schedule for the device that includes a common channel that is common to the device and the one or more neighbors at any given point in time, wherein the second channel hopping schedule is self-generated by each of the device and the one or more neighbors. The device switches from the first channel hopping schedule to the second channel hopping schedule, in response to a network event. The device causes a particular neighbor to join the network using the second channel hopping schedule.Type: GrantFiled: November 24, 2014Date of Patent: April 24, 2018Assignee: Cisco Technology, Inc.Inventors: Jonathan Hui, Wei Hong

Patent number: 9735957Abstract: According to one embodiment, techniques are provided to enable secure communication among devices in a mesh network using a group temporal key. An authenticator device associated with a mesh network stores a pairwise master key for each of a plurality of devices in a mesh network upon authentication of the respective devices. Using the pairwise master key, the authenticator device initiates a handshake procedure with a particular device in the mesh network to mutually derive a pairwise temporal key from the pairwise master key. The authenticator device encrypts and signs a group temporal key using the pairwise temporal key for the particular device and sends the group temporal key encrypted and signed with the pairwise temporal key to the particular device.Type: GrantFiled: December 19, 2014Date of Patent: August 15, 2017Assignee: Cisco Technology, Inc.Inventors: Navindra Yadav, Atul Mahamuni, Jonathan Hui, Wei Hong, Alec Woo

Patent number: 8714819Abstract: This invention is directed to an improved reclosable bag having first and second walls and an open top. The open top has first and second flexible fastener strips attached thereto. One of the strips has a profile portion forming a groove; the other strip has a profile portion forming a rib with a portion of the rib received and retained in the groove when the bag top is closed. Each of the fastener strips has a base connected to the respective walls. The bag has a slider mounted on the fastener strips which is movable longitudinally along the fastener strip to progressively separate the rib from the groove to open the bag, and is movable in the opposite direction to progressively return rib to a retained condition in the groove and create a leak-proof seal. A cradle is formed near one end of the fastener strip which is sized, constructed and arranged to receive and retain the base of the slider when the fastener strip is sealed to prevent leakage from that end of the fastener strip.Type: GrantFiled: January 25, 2007Date of Patent: May 6, 2014Assignee: Global Packaging Solutions LimitedInventors: Jonathan Hui, Mark Branson
