Publication number: 20230099263Abstract: Systems and methods are for securing link aggregation are provided. According to an embodiment, a network device in a secure domain discovers device information associated with a peer network device in an untrusted domain that is connected through a first link directly connecting a first interface of the network device to a first interface of the peer network device, and authenticates the peer while allowing at least some network traffic to continue to be transmitted through the first interface. The network device establishes a secure session between the network device and the peer over the first link when the peer network device is successfully authenticated. The network device then allows the first link to operate as part of a single aggregated logical link, including a second link coupling a second interface of the network device to a second interface of the peer network device.Type: ApplicationFiled: December 2, 2022Publication date: March 30, 2023Applicant: Fortinet, Inc.Inventors: Joseph R. Mihelich, Xiao Hu, Amit Srivastav, Norman Cheng

Publication number: 20210277439Abstract: An method of malaria detection includes providing an interdigitated sensor having a first electrode with a plurality of fingers and a second electrode with a plurality of fingers, interspersed and spaced apart from the fingers of the first electrode. A quantity of blood to be tested is received on the sensor. The blood is to be dried and is measured for at least one measurable characteristic, including a resistance of the blood. The presence of malaria infected blood is determined based on a comparison between the measurable characteristics and a predetermined threshold related to the measurable characteristics.Type: ApplicationFiled: March 4, 2020Publication date: September 9, 2021Inventors: Yu-Chung Norman Cheng, Mitchelle V.

Publication number: 20150032842Abstract: In a web page provision method and system, a user terminal transmits to a server service data and a barcode generation request associated with the service data. The server generates a service web page corresponding to the service data, and a web address of the service web page. The server generates a web address alias based on the web address and at least one alternative web address at which a specific web page is located in response to the barcode generation request from the user terminal. The server generates a two-dimensional barcode corresponding to the web address alias.Type: ApplicationFiled: July 26, 2013Publication date: January 29, 2015Inventors: Norman CHENG, Hwey-Chyi LEE

Patent number: 7782051Abstract: The present invention provides a method of handling rapid phase aliasing in magnetic resonance images arising from local magnetic susceptibility differences. The methods of the present invention can be used to estimate the field effects within an object arising from the interfaces of regions having differences in magnetic susceptibilities, and to subtract out the resulting phase from the original or source phase data prior to any further phase processing. The methods of the present invention also include a process of accurately determining the susceptibility values of multiple voxel regions based on the geometry of such regions.Type: GrantFiled: April 18, 2008Date of Patent: August 24, 2010Assignee: MR Innovations, Inc.Inventors: E.

Patent number: 7692424Abstract: A method comprises digitally representing a volume of space as a plurality of voxels and assigning real and imaginary values derived from magnetic resonance imaging data of the space to each of the voxels. Furthermore, the method comprises a steps of calculating a first complex summation of the real and imaginary values of a first set of the voxels, and calculating a second complex summation of the real and imaginary values of a second set of the voxels. Each set of voxels represents a different region of the volume of space. The regions are concentric. The method also comprises steps of using the first and second summations, along with another value quantitatively calculated from the magnetic resonance imaging data, to calculate a value that is dependent upon the approximate magnetic moment of an object within the volume of space, and digitally representing and storing said value.Type: GrantFiled: February 28, 2008Date of Patent: April 6, 2010Assignee: Magnetic Resonance Innovations, Inc.Inventors: Yu-Chung Norman Cheng, Ching-Yi Hsieh, E.
