Patents

  1. Methods for closed-loop neural-machine interface systems for the control of wearable exoskeletons and prosthetic devices. View Online
    • US patent US10092205B2, granted Oct. 2018.
    • Inventors – J. Contreras-Vidal, S. Prasad, A. Kilicarslan, N. Bhagat
    • Individual contribution – Developed the idea of subject-specific adaptive windows for segmenting EEG features, for training a machine learning algorithm, to classify motor intent (i.e., Go) vs. rest (No-go)
    • Impact – Significantly improved brain-machine interface performance over conventional fixed window approach in chronic stroke participants, as highlighted in Bhagat et al, Frontiers in Neuroscience, 2016
  2. Neuromuscular stimulation using multistage current driver circuit. View Online
    • US patent US11052249B2, granted Jul. 2021
    • Inventors – N. Bhagat, J. Contreras-Vidal 
    • Summary– A novel constant current source is developed by cascading conventional Howland current pump and current mirror circuits, to result in a low-cost, power efficient as well as high-voltage compliant neuromuscular stimulator.
  3. Device for generating, controlling, and monitoring movement using electrical stimulation
    • Inventor – N. Bhagat
    • Provisional patent (202221029416) filed in India on May 23rd, 2022.
