Systems methods are described for modifying sleep patterns based on biofeedback. The method may include identifying a target sleep pattern from a plurality of candidate sleep patterns, receiving biofeedback information from a user, identifying a stimulus pattern based on the target sleep pattern and the biofeedback information, and providing at least one stimulus to the user based on the stimulus pattern.

The present invention relates to methods and devices to consolidate memory and/or cognitive functions by monitoring brain rhythms and delivering a stimulus at an appropriate stage of sleep cycle.

System and methods are disclosed that promote a sleep stage of a user. The systems and methods determine a current sleep stage of a user during a sleep session, with the user using a respiratory therapy system during the sleep session. The systems and methods further predict an undesired sleep stage upcoming for the user during the sleep session based, at least in part, on (i) one or more user parameters, information from one or more previous sleep sessions, or a combination thereof, and (ii) the current sleep stage. The systems and methods adjust one or more control parameters of the respiratory therapy system, of one or more devices in an environment of the user, or of a combination thereof to promote a desired sleep stage of the user, thereby optimizing sleep of the user.

A sleep inducing device and a sleep management system including the same are provided. The sleep inducing device comprises: a housing unit that includes a frame of which the shape can be changed; a sensor unit that is disposed on one surface of the housing unit and includes a brain-wave measurement sensor that measures a user's brain wave; an output unit that includes a first output unit and a second output unit, wherein the first output unit is located on one side of the housing unit to output a sound or light with a first frequency, and the second output unit is located on an opposite side of the housing unit to output a sound or light with a second frequency that is different from the first frequency; and a control unit that calculates the user's sleep pattern on the basis of the brain wave signal measured by the sensor unit and changes the output signal of the output unit such that the sleep pattern approaches a predetermined value.

A system delivers auditory sleep stimulation. It is able to generate masking sounds for masking external noise as well as sleep stimulation tones for promoting deep sleep. Noise masking sounds are provided in a frequency range including first and second frequency bands, before the onset of sleep. In response to the detection of particular sleep characteristics (such as a particular sleep stage), the noise masking sounds in the second frequency band are stopped. Instead, sleep stimulation tones are provided in the second frequency band. Thus, noise masking continues but the sleep stimulation tones are not masked.

Provided are systems, methods, and devices for biomarker shaping and sleep profile enhancement. Systems include a plurality of electrodes configured to be coupled to a brain of a user and configured to obtain a plurality of measurements from the brain of the user, and an interface configured to obtain the plurality of measurements from at least the plurality of electrodes. Systems also include a processing device comprising one or more processors configured to generate a first target sleep profile for the user based, at least in part, on the plurality of measurements and a plurality of biomarkers, the processing device being further configured to generate a plurality of stimulus parameters based, at least in part, on the target profile.

Methods include receiving, via a user interface, a plurality of input parameters associated with a sleep profile of a user, the plurality of input parameters representing at least one sleep profile target, generating, using one or more processors of a processing device, a plurality of sleep parameters based, at least in part, on the received plurality of input parameters, the plurality of sleep parameters representing one or more changes to one or more biomarkers of the user, and generating, using one or more processors of the processing device, a plurality of stimulation parameters based, at least in part, on the plurality of sleep parameters, the plurality of stimulation parameters representing stimuli configured to implement the identified changes for each of the identified biomarkers of the user's sleep profile.

The present invention relates to systems for brain stimulation during sleep and methods for increasing vividness of a subject's dreams or for directing the subject matter of a subject's dreams. The system comprises a brain stimulation module and at least one of a brain energy source and/or a hypnotic source. The methods involve administering to a subject a brain energy molecule and/or a hypnotic and providing to the subject during restorative sleep a sensory stimulation.

A valve structure for treating a patient suffering from obstructive sleep apnea is provided. The valve structure is connected to an air flow generator and is connected to a mask that covers at least the nostrils of a patient. The valve structure includes an inlet pressure port attached to the air flow generator and an expiration valve that includes an expiratory membrane, a primary seat and a secondary seat. During inspiration, the expiratory membrane forms a seal with the primary seat, and during expiration, the expiratory membrane forms a seal with the secondary seat.
