Sleep performance systems and methods of using the same are disclosed. The sleep performance systems can improve the quality of sleep by making one or more recommendations to the subject for increasing a sleep quality score. The sleep performance systems can have one or more electroencephalography (EEG) electrodes configured to measure a subject’s brain activity during sleep. The sleep performance systems can have a processor configured to quantify the quality of the subject’s slow-wave sleep by determining one or more sleep performance scores associated with the measured brain activity. The sleep performance systems can recommend and/or activate sleep improvement programs based on various threshold scores.

The present invention provides systems, methods, and articles for temperature conditioning a surface. An article is formed from a first layer having a plurality of openings and a second layer having a corresponding plurality of openings. At least one interior chamber constructed and configured to retain a fluid without leaking is defined between an interior surface of the first layer and an interior surface of the second layer. At least one flexible fluid supply line delivers the fluid to the at least one interior chamber. At least one flexible fluid return line removes the fluid from the at least one interior chamber. At least one control unit that is operable to selectively cool or heat the fluid is attached to the at least one flexible fluid supply line and the at least one flexible fluid return line.

The present disclose generally relates to systems and methods for active titration of one or more cranial or peripheral nerve stimulators to treat obstructive sleep apnea. The active titration can be accomplished in an automated fashion by a closed-loop process. The closed-loop process can be executed by a computing device that includes a non-transitory memory storing instructions and a processor to execute the instructions to perform operations. The operations can include defining initial parameters for the one or more cranial or peripheral nerve stimulators for a patient; receiving sensor data from sensors associated with the patient based on a stimulation with the one or more cranial or peripheral stimulators programmed according to the initial parameters; and adjusting the initial parameters based on the sensor data.

In an embodiment a method for detecting an activity of a first eye of a user using glasses includes acquiring, by a controller and through first and second electrodes, a first electrostatic charge variation signal indicative of a difference between the electrostatic charge variations detected by the first and the second electrodes, verifying, by the controller, a presence of one or more blink patterns in the first electrostatic charge variation signal, each blink pattern being indicative of a respective click or of a respective blink, the click being a voluntary blink of the first eye and the blink being an involuntary blink of the first eye, when the first electrostatic charge variation signal has the one or more blink patterns, determining, by the controller for each blink pattern, whether a first condition is verified, when the first condition is not verified, detecting, by the controller, a respective blink and when the first condition is verified, detecting, by the controller, a respective click.

Various embodiments of a hearing device and a method of forming such device are disclosed. The device includes a housing adapted to be worn on or behind an ear of a wearer and includes a housing body and a top plate connected to the housing body. The hearing device further includes a sensor disposed on at least one of a first side surface and a second side surface of the housing body. The sensor is adapted to be in contact with either a pinna or a skull of the wearer.
