Abstract: Systems and methods for assessing compliance with position therapy. In an embodiment, position therapy is provided to a user while the user is wearing a position therapy device. The position therapy comprises, by the device, collecting positional data, determining positions of the user over a time period based on the positional data, and, when it is determined that the user is in a target position, providing feedback to the user to influence the user to change to a non-target position. In addition, the device stores a duration of use in its memory. The duration of use indicates a duration that the user has used the wearable position therapy device in each of one or more positions. An assessment of the user's compliance with the position therapy is then provided based, at least in part, on the duration of use.

Abstract: A wearable positional therapy device for influencing a position of a user. In an embodiment, the device comprises a position detector that generates positional data used to determine a position of a user, a feedback generator that generates feedback to the user, and a microcontroller. The microcontroller is configured to receive and analyze the positional data to determine whether the user is in a target position, while, in response to the device being turned on or a reset operation, delaying feedback for a delay period. If it is determined that the user is in the target position during the delay period, no feedback is provided. However, if it is determined that the user is in the target position following the delay period, feedback is provided to the user to induce the user to change to a different, non-target position.

Abstract: 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.

Abstract: 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.

Abstract: 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.
