Publication number: 20230247142Abstract: A method and system for management of multi-party communications that is capable of intelligently assessing a first party/requestor's need and automatedly matching the first party's need to a suitable second party resource that is most probable to meet that need in an efficient manner. The system effectively serves as a chatbot-based (text-based or voice-based) switchboard operator that allows requestors to state a need for a service or consultation, and then automatedly have that need researched and/or matched to the most appropriate resource/service provider based on real-time automated inquiry and/or known data from past research. Further, the system is capable of contacting one or more resources/service providers, confirming that a particular resource/provider can meet the current need, and also coordinating/facilitating a communication session between the first party/requestor and the second party/resource without the need for human intervention.Type: ApplicationFiled: January 31, 2023Publication date: August 3, 2023Inventors: Jonathan Meade, John DiGiovanni, John Evans

Publication number: 20230205867Abstract: A device captures, at the time of authentication to a secured session, secondary authentication data of the user that has authenticated using primary authentication credentials. Then, during the session, the system is caused to re-authenticate the user using the secondary authentication credentials (such as original and current user's face images). The system actively monitors the face visible to a camera of the computing device. The system compares the current face to the face image captured at the time of authentication. If the system fails to detect the same face captured initially at the time of authentication, then the system automatedly ends or otherwise locks the session to secure that session from an unauthorized user. Accordingly, the system does not rely merely upon initial authentication for an entire session, but rather reauthenticates the user during a single session in order for the session to be permitted to continue.Type: ApplicationFiled: December 22, 2022Publication date: June 29, 2023Inventors: Jonathan Meade, John DiGiovanni, John Evans, Erwin Bautista

Publication number: 20230172450Abstract: A system for remote motor and sensory function testing may involve use of patent and clinician computing devices, a patient testing device, and a clinician control device. A Remote Testing System (RTS) may coordinate displays of information among the devices in support of a test. A clinician or the RTS may cause display of instructions for guiding a patient in using the patient testing device. A clinician may receive feedback from the patient's interaction during the test session, or during a later session. The clinician control device may be used to control functioning of the patient testing device, in support of the test. The clinician control device may provide haptic or other feedback during the test session or during a later session. The system may track patient performance across multiple sessions and initiate follow-up test sessions as a result of data gathered in one or more prior test sessions.Type: ApplicationFiled: October 12, 2022Publication date: June 8, 2023Inventors: John DiGiovanni, Jason Mastriana

Publication number: 20230046250Abstract: A computerized system and method for user interface management provides an augmented reality-based experience that delivers real-time visual cues to a cognitively impaired person, that monitors visual recognition performance, and that provides visual recognition training based on observed visual recognition performance. The system uses image/facial recognition to identify persons/places/objects encountered by a person/dementia sufferer and captured by a camera of a computing device, retrieves information associated with identified person/place/object, and displays retrieved information associated with identified person/place/object to the person/dementia sufferer via the device, e.g., in an augmented reality overlay to an image captured by the camera. The information may identify the identified person's relationship with dementia sufferer and other pertinent details. Accordingly, for example, a person with cognitive impairment can quickly assess who is approaching them, based on facial recognition.Type: ApplicationFiled: August 10, 2022Publication date: February 16, 2023Inventors: Catherine Margaret Burch, James Michael Ellison, Alexis Celine Ryan, Jennifer Czerepak Rittereiser, Jason Anthony Mastriana, Erwin Villareal Bautista, Jonathan Michael Meade, John DiGiovanni, Kelsey Ann Kosinski, Samantha Joy Taylor, John Eric Evans

Patent number: 7787733Abstract: An optical transmission fiber is formed to include a relatively low-index, relatively thin outer cladding layer disposed underneath the protective polymer outer coating. Stray light propagating along an inner cladding layer(s) within the fiber will be refracted into the thin outer cladding (by proper selection of refractive index values). The thin dimension of the outer cladding layer allows for the stray light to “leak” into the outer coating in a controlled, gradual manner so as to minimize heating of the coating associated with the presence of stray light. The inventive fiber may also be bent to assist in the movement of stray light into the coating.Type: GrantFiled: September 8, 2008Date of Patent: August 31, 2010Assignee: Furukawa Electric North America, Inc.Inventors: David John DiGiovanni, Yoshihiro Emori, Michael Fishteyn, Clifford Headley
