| 20100087701 | Systems and Methods for Optimization of Sleep and Post-Sleep Performance - Systems and methods for optimizing the sleep and post-sleep performance of individuals regardless of their environment and time available for sleep are provided. The systems and methods take into account factors that determine the effects of a sleep episode on dexterity, cognitive functions and the subjective feeling of fatigue after sleeping: duration and sleep architecture of the sleep episode, point on the circadian cycle at which the episode occurred, the amount of sleep debt accumulated prior to the episode and the subject's susceptibility to sleep deprivation. The systems and methods include monitoring of sleep architecture over a longer period of time, measurement of accumulated sleep debt and assessment and/or tailoring of the sleep architecture for each subsequent sleep episode, determining a desired sleep state in which the subject should be in, and generating sensory stimuli for guiding the subject to the desired sleep state. | 04-08-2010 |
| 20100145201 | METHOD FOR MEASURING CENTRAL VENOUS PRESSURE OR RESPIRATORY EFFORT - Photoplethysmography (PPG) is obtained using one red (e.g., 660 nm) and one infrared (e.g., 880 to 940 nm) light emitting diode with a single photo diode in combination with a pressure transducer thereby allowing both CVP and SpO2 to be measured simultaneously. The system also includes sensors capable of measuring position, angle and/or movement of the sensor or patient. Once the PPG signal is acquired, high pass adaptive and/or notch filtering can be used with one element of the filter from the red and infrared signals used to measure the arterial changes needed to compute SpO2 and the other element of the signal can be used to measure CVP changes. | 06-10-2010 |
| 20100240982 | System for the Assessment of Sleep Quality in Adults and Children - Systems and methods for assessment of sleep quality in adults and children are provided. These techniques include an apparatus worn above the forehead containing the circuitry for collecting and storing physiological signals. The apparatus integrates with a sensor strip and a nasal mask to obtain the physiological signals for the user. The form factor of this apparatus is comfortable, easy to self-apply, and results in less data artifacts than conventional techniques for capturing physiological data for analyzing sleep quality. Neuro-respiratory signals are analyzed using means to extract more accurate definitions of the frequency and severity of sleep discontinuity, sleep disordered breathing and patterns of sleep architecture. Biological biomarkers and questionnaire responses can also be compared to a database of healthy and chronically diseased patients to provide a more accurate differential diagnosis and to help determine the appropriate disease management recommendations. | 09-23-2010 |
| 20100268096 | Method and Apparatus For Non-Invasive Assessment of Hemodynamic and Functional State of the Brain - A method and apparatus for assessment of hemodynamic and functional state of the brain is disclosed. In one embodiment, the method and apparatus includes non-invasive measurement of intracranial pressure, assessment of the brain's electrical activity, and measurement of cerebral blood flow. In some embodiments, the method and apparatus include measuring the volume change in the intracranial vessels with a near-infrared spectroscopy or other optical method, measuring the volume change in the intracranial vessels with rheoencephalography or other electrical method, and measuring the brain's electrical activity using electroencephalography. | 10-21-2010 |
| 20100292545 | INTERACTIVE PSYCHOPHYSIOLOGICAL PROFILER METHOD AND SYSTEM - An efficient, objective, flexible and easily deployable system for conducting evaluations of mental and physiological state and recommending individualized treatment to improve said state is described. The method and system are based on commensurate measurement of mental functions, levels of stress and anxiety, and/or biologically active molecules such as neurotransmitters, immune markers including cytokines and hormones. The method and system are designed to assess an individual's cognitive function and the underlying physiology in order to delineate various disease processes, injuries, drug states, training stages, fatigue levels, stress levels, aging processes, predict susceptibility to stress and/or sleep deprivation, identify aptitude for training and/or characterize effects of any experimental conditions. The system and method may be used in recommending individualized treatment protocols, as well as to guide the treatment process by assessing the efficacy of such therapies in the clinical trials process. | 11-18-2010 |
| 20110105859 | Adaptive Performance Trainer - Techniques for accelerating training through optimization of the psychophysiological state of the trainee are provided. These techniques include an adaptive performance training system configured to acquire, analyzed, display, and translate data that reflects the psychophysiological state of the user, including the electrical activity of the brain (EEG), the heart (EKG), the musculature (EMG), respiration and other parameters that characterize the state of the user in real-time. The system includes a plurality of feedback mechanisms for providing visual, auditory, and/or tactile feedback based on the current psychophysiological state of the user and for facilitating moving the user toward a goal psychophysiological state for performing a particular task and for optimizing performance of that task. | 05-05-2011 |
| 20110132378 | Systems and Methods For Controlling Position - Systems and methods for controlling the position of a user of a wearable positional therapy device are provided. The wearable position therapy device can be configured to monitor and store physiological signals that can be used to assess sleep quality and sleeping position of a user. The device can be configured to be worn around the head, the neck, or body of the user. The device can be configured to provide feedback to a user if the user is sleeping or is positioned in a target position to induce the user to change positions. The feedback can be provided by one or more haptic motors that can be configured to provide various levels of feedback and the level of feedback can be customized based on the user's reaction to the feedback. | 06-09-2011 |
