Patent number: 12245866Abstract: A method for determining if a tissue is ganglionic is provided. The method comprises a) generating at least one hyperspectral Raman image of a tissue from a region of interest in a tissue suspected to contain ganglion cells that was optionally identified by a method comprising autofluorescence (AF) and Second Harmonic generation (SHG) imaging of the tissue; and b) analyzing any of the images for one or more of the following: i) optical excitation; ii) chemical information or emission spectra; or iii) AF, SHG, and/or Raman signatures, wherein the analysis provides indicators that the region of interest is either ganglionic or non-ganglionic. A system for analysis of in vivo tissue or ex vivo tissue samples including a multiphoton autofluorescence microscope, a Second Harmonic Generation microscope, and a hyperspectral Raman microscope in operative communication is also provided.Type: GrantFiled: November 6, 2020Date of Patent: March 11, 2025Assignee: The Regents of the University of CaliforniaInventors: James Chan, Payam Saadai

Patent number: 11805113Abstract: Systems, apparatuses, and methods are described for establishing, or re-establishing, trust for a network device. A user device may send, via a network device, a service request to establish trust for the network device in a network. The service request may comprise, or may allow look up of, identifying information for the network device, such as a network address. Trust of the network device may be established, at least in part, by confirming the network address (or other identifying information) associated with the network device, and/or by confirming certain devices that are in communication with the network device. An authentication token may be sent to the network device for reconnecting to the network.Type: GrantFiled: July 6, 2022Date of Patent: October 31, 2023Assignee: Comcast Cable Communications, LLCInventors: James Chan, Weston Schmidt

Publication number: 20230144444Abstract: In accordance with one or more embodiments, aspects of the disclosure may provide efficient, effective, and convenient ways of managing network devices. In particular, a client router may connect to an upstream virtual gateway. The virtual gateway may manage a large number of client devices. Each client router may be represented virtually within the gateway as a virtual router. The virtual gateways may be distributed regionally, in order to manage large numbers of client routers and/or to reduce transmission delays. The virtual gateways may be managed by a gateway controller. The gateway controller may be centralized, and perform various configuration functions, such as configurations for hardware, logical networking, or content access policies. In some instances, messages sent between the gateway controller using a first protocol and the client router using a second protocol may be translated by a protocol agent.Type: ApplicationFiled: December 19, 2022Publication date: May 11, 2023Inventors: Mani Ramasubramani, Andrea Peiro, Jeffrey Barberio, Kris Bransom, Michael Chen, Weston Schmidt, James Chan, John Robinson
