  • Patent number: 11583201
    Abstract: The invention consists of a device to evaluate hemodynamic response generated by the spinal cord in response to a suprasensorial stimulus applied to a peripheral nerve (medium or posterior tibial) by the use of functional near-infrared spectroscopy (fNIRS). The device consists of 3 main components, an electrical stimulator, an optical recording unit and a signal processing and control module. The device allows non-invasive, comfortable, harmless, portable, home-based, and low-cost evaluation of changes in local hemodynamic parameters in response to neuronal activation of the spinal cord by electrical stimulation of a peripheral nerve. The invention also includes a corresponding method of using the device and monitoring the spinal function.

  • Patent number: 10810739
    Abstract: Example embodiments provide real time quality monitoring of a magnetic resonance imaging (MRI) scan. Data associated with an MRI scan of a particular patient is received. The data is sequential MRI data associated with various times. A rate of change of the sequential data is determined with reference to the various times. It is determined whether the rate of change of the sequential data meets a first configurable threshold. It is determined whether the rate of change of the sequential data meets a second configurable threshold. The sequential data is classified based on whether the rate of change of the sequential data meets the first and second configurable thresholds.

  • Publication number: 20200038653
    Abstract: Brain impairment, for example due to stroke, is corrected in order to improve body movement. An fNIRS device is positioned over the motor cortex of non-impaired individuals, and blood oxygen in locations of the brain is analyzed to determine brain activity corresponding to a particular body movement. The movements are statistically analyzed, and are compared with fNIRS data gathered from a movement impaired individual attempting the same movement. A weighted value corresponding to the desired brain activity is generated using the statistical analysis, and is graphically displayed to the movement impaired individual during the attempts. This produces a feedback loop relating to the movement which can be repeated to produce brain plasticity in the impaired individual to facilitate the movement. Additionally, correct brain activity can be used to cause the application of an electrical signal to muscles of the body to produce the desired movement.

  • Publication number: 20110028827
    Abstract: A multivariate, pattern-based system and method for recognition of brain states and generation of feedback considering both the spatial and temporal pattern of network of brain activity is described. The system can be applied for enhancing a desired function or behavior, or to alleviate a behavioral or neurological problem. The system can also be used to investigate the spatiotemporal evolution of a network of brain activity corresponding to a brain function, by changing the activity as an independent variable and studying its effect on behavior.

  • Publication number: 20050021393
    Abstract: A smart interactive billboard for allowing or other devices implemented with the smart billboard to display electronic/computer-based information and become interactive includes a transceiver adapted to communicate interactively with a server and at least one or more client devices to allow users to be interactive with the implemented billboards or other devices. A CPU including software controls the implemented billboards or other devices. A memory stores information received or uploaded to the implemented billboards or other devices from the server and client devices, and a display unit displays the information on the implemented billboards or other devices.
