An erotic dream induction apparatus includes an inflatable air bladder, such as a rubber balloon, to induce sexual arousal via genital stimulation. The air bladder is brought into contact with either the penis or vagina of the user, and/or is inserted into the anus and/or vagina of the user. In one embodiment, the air bladder is brought into contact with the penis, vagina, and/or anus of the user by being maintained in position near, against, or around the penis, vagina, and/or anus by means of straps or pockets in stimulation underwear, such that when the air bladder is inflated, the air bladder makes contact with at least a portion of the penis, vagina, and/or anus of the user. The air bladder is repeatedly inflated and deflated by pumps and/or valves.

A system for monitoring and controlling a heart rate includes an interface for communicating with a heart rate monitor and a haptic device. The system also includes a processor and memory. The memory includes programmed instructions to cause the processor to determine a natural heart rate of a user, determine a target rate for the user, and cause the haptic device to provide haptic input to the user to adjust the natural heart rate to the target heart rate.

A sleep-retraining method includes monitoring, via a sleep-retraining beanie, electrical brain-activity of a user during an initial sleep session. The electrical brain-activity is reflected in the form of brain-activity data. The method further includes receiving, via an electronic device, physical-activity data for the user that is indicative of a physical activity of the user occurring after the initial sleep session. The method further includes, based on the brain-activity data and the physical-activity data, suggesting an optimal sleep session for the user that has an improved sleep quality relative to the initial sleep session.

Described is a closed-loop intervention control system for memory consolidation in a subject. During operation, the system simulates memory changes of a first memory in a subject during waking encoding of the memory, and then while the subject is sleeping and coupled to an intervention system. Based on the simulated memory changes, the system predicts behavioral performance for the first memory, the behavioral performance being a probability that the first memory can be recalled on cue. The system can be used to control operation (e.g., turn on or off) of the intervention system with respect to the first memory based on the behavioral performance of the first memory determined by the simulation.

Apparatus, systems, and methods are provided for treating obstructive sleep apnea. A unitary valve assembly removably located inside the exterior profile of a nasal pillow mask uses positive airway pressure from a low-flow hose to automatically create an on-demand therapeutic air splint in the pharynx. During inspiration the mask's valving system allows room air to be inspired. During exhalation another valve governs therapeutic backpressure equal to the prescribed pressure setting of the CPAP blower machine. The mask may be worn when the CPAP blower machine is off, and systems are provided for turning the CPAP blower machine on only when needed.

Described is a system including a sensor and a processing arrangement. The sensor measures data corresponding to a patient's breathing patterns. The processing arrangement analyzes the breathing patterns to determine whether the breathing patterns are indicative of a REM sleep state. In another embodiment, the processing arrangement analyzes the breathing patterns to determine whether the breathing patterns are indicative of one of the following states: (i) a wake state and (ii) a sleep state. In another embodiment, a neural network analyzes the data to determine whether the breathing patterns are indicative of one of the following states: (i) a REM sleep state, (ii) a wake state and (iii) a sleep state. In another embodiment, the processing arrangement analyzes the data to determine whether the breathing pattern is indicative of an arousal.

A device for inducing sleep according to the present invention comprises: a sensor configured to be wearable on a user's body, and contacting a part of the user's body to obtain a sleep-related signal; an output module that outputs a synthesized sound source obtained by mixing a first sound source for inducing the user's sleep and a second sound source different from the first sound source; and a control unit. The control unit transmits the sleep-related signal to an external device, receives sleep state information of the user according to an analysis of the sleep-related signal from the external device, and adjusts an output ratio of the first and second sound sources constituting the synthesized sound source and outputs the first and second sound sources, on the basis of the received sleep state information of the user. Accordingly, the user can fall asleep more comfortably, sleep soundly, and wake up refreshed.

A dream stimulator may include a substrate and a plurality of electrodes positioned along a first side of the substrate. The stimulator also may include a stimulator coupled to the substrate. At least one lead may couple the plurality of electrodes to the stimulator. Additionally, a band may be positioned along a second side of the substrate and about each of the plurality of electrodes.
