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.

This invention is a system which automatically changes the firmness and/or configuration of a portion of a mattress on which a person sleeps based on changes in the person's body motion, body configuration, and/or snoring. The person's body motion or body configuration can be measured by a wearable motion sensor. The firmness and/or configuration of the portion of the mattress can be changed by inflation or deflation of the mattress or by electromagnetic adjustment of the compressive resistance of mattress springs.

In at least one embodiment, the lens works in conjunction with a second lens and/or an external device to monitor for a medical condition or to perform a test protocol of the wearer. Examples of the at least one sensor include an eyelid position sensor system, an eye movement sensor system, a biosensor, a bioimpedance sensor, a temperature sensor, and a pulse oximeter.

Systems and apparatus for monitoring physiological electrical activity of an individual include a first electrode unit for receiving a first signal indicative of electrical activity at a first location on a body of the individual and a second electrode unit for receiving a second signal indicative of electrical activity at a second location on the body of the individual. Each of the first and second electrode units may be operated in a field-sensing mode wherein the electrode unit is placed on or in proximity to the individual's skin. The first and second electrode units comprise a capacitive sensor element, and the capacitive sensor element of each of the electrode units comprising an electrodynamic sensor which is sensitive to electromagnetic waves; and an antenna comprising an electrically conductive radiating element for receiving electromagnetic waves. The field-sensing mode can be either non-contact field-sensing mode wherein the electrode unit does not contact the individual's skin, or a contact field-sensing mode wherein the electrode unit is placed directly on the individual's skin.
