  • Patent number: 11020601
    Abstract: This accessory adapts external cardiac defibrillation systems to enable safe defibrillation, pacing, and cardioversion inside the MRI bore with minimal effect on MR image quality. Commercially available external defibrillators are not designed to work in the MRI environment. An MR-compatible defibrillator is needed to safely perform cardiovascular MRI, in particular MR-guided interventional cardiovascular procedures, such as cardiac electrophysiology studies and cardiac catheterization. This accessory includes nonmagnetic defibrillator housing with MRI safety features, provides interface for MRI-compatible physiological monitoring, and optimizes defibrillator operation for the MRI environment. The accessory may include MRI-compatible modules for monitoring/recording electrocardiogram, blood pressure, pulse oximetry, and other physiological signals. It may also include a wireless transmitter and at least one module for electrical energy generation and/or stimulation.

  • Patent number: 10314508
    Abstract: Method for processing a brain wave signal (4) obtained from a person using a brain wave detector (5). One or more stimuli are applied to the person in which each of the one or more stimuli comprises a pseudo random noise component modulating the stimulus intensity. A brain wave signal (4) is detected after applying the one or more stimuli. The detected brain wave signal is processed to calculate which of the one or more stimuli is present in the detected brain wave signal using correlation techniques. The pseudo random noise component comprises a pseudo random noise sequence of the class of maximum length sequences, which are further modulated with twice their associated bit frequency.

  • Patent number: 10198958
    Abstract: Training methods and apparatus wherein a training environment is activated only when a trainee is in a focused attention state. A brainwave monitor is employed for determining level of attention. The training environment is activated when the level of attention of the trainee is at or above a predetermined attention threshold. Activation of the training environment provides feedback to the trainee that he or she is in a focused attention state, and at the same time provides the incentive to remain in the focused attention state. A focused attention state is important if not required for training/learning success. The method and apparatus may be employed for training individual trainees, as well as for training team member trainees.

  • Patent number: 10155113
    Abstract: A neural physiological method and apparatus for keeping the brain in wakefulness, in which the trigeminal nerves on the forehead are stimulated with a mild electrical current neuronal modulating signal of a range of frequencies and amplitudes in combination transmitted to the brain functional site locus coeruleus, resulting in inhabitation of the brain functional site thalamic reticular nucleus such that the thalamic reticular nucleus does not release inhibitory neurotransmitters for blocking the communication pathways between the thalamus and the cortical regions in the brain, keeping the brain in wakefulness.

  • Patent number: 10143397
    Abstract: An electrode holding device is described using a headset having a neutral curvature with a radius smaller than a human skull. The headset adapted to provide spring load force against the human skull at the first and the second ends where first and second respective electrode holding panels are attached. The electrode holding panels conform to the human above the ears. The electrode panels are adapted to pivot about pivot points on the ends of the headset. The panels are adapted to contact the human skull under pressure from spring load force generated from the headset bent beyond the neutral curvature of the headset. The headset can in certain examples be further adapted in certain to accommodate an arm having an a third electrode panel that possesses a third electrode assembly, the third electrode assembly adapted to be spring loaded against and in contact with the human forehead.

  • Patent number: 10130278
    Abstract: A device for performing EEG which consists of an elastic head strap, electrodes, and a wireless transmitter. The wireless transmitter, which displays indicators of electrode impedance, is secured to a patient using a docking station attached to the head strap at the crown of a subject's head and is placed into electrical communication with the electrodes using conductive thread sewn into the head strap. A simplified user interface comprising graphical elements improves the detection of brain wave patterns.

  • Patent number: 9913593
    Abstract: Medical device systems and methods for operating medical device systems conserve energy by efficiently managing computational demands of the systems. Signals from a subject are processed and analyzed and an estimate of a propensity for a subject to have a neurological event is determined. Based on the results of the analysis and the estimate, further analysis may be performed and the estimate may be refined. Succeeding cycles of signal measurement and analysis are scheduled depending on the results of the analysis and the estimate. The schedule may be varied temporally or with regard to the types and intensities of analyzes performed.
