Patent number: 11497418Abstract: A neuroactivity monitoring system includes a camera configured to acquire image data of a patient positioned on the patient support and a monitoring device in communication with the camera. The monitoring device uses the acquired image data of the camera to identify and track patient landmarks, such as facial and/or posture landmarks, and, based on the tracked movement, characterize patient neuroactivity.Type: GrantFiled: February 5, 2020Date of Patent: November 15, 2022Assignee: General Electric CompanyInventors: Cynthia Elizabeth Landberg Davis, Guangliang Zhao, Tzu-Jen Kao, Aghogho Obi, Nancy Cecelia Stoffel

Patent number: 11166677Abstract: The disclosed systems and methods for monitoring a patient in a medical setting may include various types of sensors that obtain data indicative of one or more patient parameters and one or more environmental parameters. One or more processors may process the data to identify a correlation, or causal relationship, between the one or more patient parameters and the one or more environmental parameters. Thus, the systems and methods may be used to identify particular environmental parameters that affect a particular patient to facilitate creation of a suitable environment for the particular patient. The disclosed monitoring systems and methods may be especially useful for sensitive, high-risk, and/or non-verbal patients, such as infants in a neonatal intensive care unit (NICU).Type: GrantFiled: March 6, 2019Date of Patent: November 9, 2021Assignee: GENERAL ELECTRIC COMPANYInventors: Cynthia Elizabeth Landberg Davis, Esmaeil Heidari, Aghogho Obi, John Eric Tkaczyk

Publication number: 20200281496Abstract: The disclosed sensor assembly may be used in a patient monitoring system to monitor one or more physiological parameters of a patient. The sensor assembly may include a substrate and one or more electrodes, which may include a lattice structure to limit a contact area between the one or more electrodes and skin of the patient. The sensor assembly may include connectors or connector assemblies that facilitate connection between the one or more electrodes and a data acquisition unit. The sensor assembly may be especially useful for patients with sensitive skin, such as infants in a neonatal intensive care unit (NICU).Type: ApplicationFiled: March 6, 2019Publication date: September 10, 2020Inventors: Aghogho Obi, Nancy Cecilia Stoffel, Steven M. Falk, Thom Valent, Mohammad Khair, Karen Starr

Patent number: 7084630Abstract: Multi-modal coils for coupling MRI RF signals from an anatomical region(s) to be imaged. The coil includes a segmented annular base ring conductor including a plurality of capacitances disposed between the segments, and at least one arcuate conductor symmetrically connected at each end to the base ring, one end terminating in direct contact with the base ring, the other end electrically connected to the base ring via two of the capacitive electrical connections. The RF coil is operable in multiple receiving modes in phase quadrature to establish a rotating magnetic field phasor orthogonal to the temporally constant uniform magnetic field of the magnetic resonance instrument. The RF coil can be combined with a second RF coil to simultaneously image two anatomical regions.Type: GrantFiled: February 27, 2004Date of Patent: August 1, 2006Assignee: Worcester Polytechnic InstituteInventors: Reinhold Ludwig, Gene Bogdanov, Aghogho Obi
