  • Patent number: 11540749
    Abstract: The disclosed embodiments provide systems and methods for predicting presence of one or more neurological deficits. The system may include a microphone, a camera, one or more memory devices storing instructions, and one or more processors configured to execute the instructions to extract audio information including a period density entropy coefficient and a mel frequency cepstral coefficient from an audio feed received from the microphone. Additionally, the instructions may cause the processor to determine position and depth information of eye movement from a video feed received from the camera and detect features of interest including facial landmarks, spatial orientation of limbs, and positional information of limb movements from the video feed. The one or more processors may further extract the features of interest from the video feed and process the extracted features of interest by aligning the extracted features of interest to a common reference.

  • Publication number: 20220319707
    Abstract: An automated and quantitative facial weakness screening framework that utilizes a Bi-LSTM network to model the temporal dynamics among the shape and appearance features. The technique is beneficial to assist the paramedics or other users to identify the facial weakness in the field or, more importantly, whenever expertise in neurology is not available either for emergency patient triage (e.g., pre-hospital stroke care) or chronic disease management (e.g., Bell's palsy rehabilitation screen), leading to increased coverage and earlier treatment. The technique provides visualizable and interpretable results to increase its transparency and interpretability. The technique provides for inexpensive solutions that can be used in areas underserved by non-neurologists to more readily identify neurological deficits such as facial weakness in the field or other environment.

  • Patent number: 10846370
    Abstract: A method for facilitating mobile telemedicine for a suspected stroke case can include initiating, with an evaluation device, a prehospital mobile telemedicine videoconference with a remote device when a projected amount of time exceeds a threshold. The method can include determining for presentation, a set of specified symptoms of a stroke, the specified symptoms obtained remotely using the prehospital mobile telemedicine videoconference, obtaining input from a user, including information indicative as to whether a patient is exhibiting symptoms of a stroke, and in response to obtaining input, transmitting, from the evaluation device to the remote device, the information indicative as to whether the patient is exhibiting symptoms of a stroke. The method can include generating a medical alert, at the evaluation device, the medical alert including patient information and the information indicative as to whether the patient is exhibiting symptoms of a stroke.
