Publication number: 20110132378Abstract: 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.Type: ApplicationFiled: June 4, 2010Publication date: June 9, 2011Applicant: ADVANCED BRAIN MONITORING, INC.Inventors: Daniel J.

Publication number: 20100292545Abstract: 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.Type: ApplicationFiled: May 14, 2009Publication date: November 18, 2010Applicant: ADVANCED BRAIN MONITORING, INC.Inventors: Chris Berka, Daniel J.

Publication number: 20100240982Abstract: 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.Type: ApplicationFiled: March 17, 2010Publication date: September 23, 2010Applicant: ADVANCED BRAIN MONITORING, INC.Inventors: Philip R.

Publication number: 20100145201Abstract: 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.Type: ApplicationFiled: February 18, 2010Publication date: June 10, 2010Applicant: ADVANCED BRAIN MONITORING, INC.Inventors: Philip R.

Publication number: 20080146893Abstract: A system for predicting risk for perioperative complications is described including a user device for receiving a set of risk factors to determine perioperative complications for a patient including patient data useful to determine the likelihood of obstructive sleep apnea. The system also includes an acquisition module to receive data from an obstructive sleep apnea sleep study of the patient. Further a determination module can determine the severity of obstructive sleep apnea for the patient. The system can also include an analysis module having a predictive model that incorporates one or more prediction equations for predicting perioperative complications derived from one or more databases having multiple patient data relevant to predict perioperative complications.Type: ApplicationFiled: December 12, 2007Publication date: June 19, 2008Applicant: ADVANCED BRAIN MONITORING, INC.Inventors: Daniel J.

Patent number: 7297119Abstract: In a technique for collecting and analyzing physiological signals to detect sleep apnea, a small light-weight physiological monitoring system, affixed to a patient's forehead, detects and records the pulse, oximetry, snoring sounds, and head position of a patient to detect a respiratory event, such as sleep apnea. The physiological monitoring system may contain several sensors including a pulse oximeter to detect oximetry and pulse rate, a microphone to detect snoring sounds, and a position sensor to detect head position. The physiological monitoring system also can contain a memory to store or record the signals monitored by the mentioned sensors and a power source. The physiological monitoring system may be held in place by a single elastic strap, thereby enabling a patient to use the system without the assistance of trained technicians.Type: GrantFiled: August 25, 2004Date of Patent: November 20, 2007Assignee: Ares Medical, Inc.Inventors: Philip R.
