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.

According to one embodiment, a control device includes a user interface device. The user interface device includes an operation receiver that is capable of receiving a command operation for a movable part of the electric furniture. At least one of a brightness and a color of at least a portion of the user interface device changes on the basis of a fluctuation of a first signal. The first signal corresponds to a biological signal that includes at least one of the respiration and the heartbeat of the user of the electric furniture.

A method for monitoring health of a subject based on a physiological response to physical exertion, by processing circuitry of a medical device system, is described that includes detecting a plurality of exertion events of the subject based on a first sensed signal that varies as a function of movement of the subject. The method further includes determining a response of a physiological parameter of the subject to the exertion event for each of the detected exertion events based on second sensed signal that varies as a function of the physiological parameter. The method further includes determining that a change in the responses over time crosses threshold and generating an alert to a user based on the determination that the change crosses the threshold.

A method, intended for the evaluation of the quality of at least one periodic or quasi-periodic physiological signal, which includes the steps of: segmenting the physiological signal temporally into a plurality of signal segments; for each given signal segment, determining a distance representative of a shape difference between the given signal segment and at least one signal segment temporally offset relative to the given signal segment; and determining a quality index of the given signal segment according to the distance determined for the given signal segment.

Disclosed are one or more proximity sensors. At least one of the proximity sensors includes a first dielectric layer, an electrically conductive layer, and an electrode. The first dielectric layer includes an inner surface and an outer surface. The electrically conductive layer is positioned proximate to one of the inner surface or the outer surface of the first dielectric layer. The electrode includes an outer surface. The outer surface of the electrode is positioned proximate the inner surface of the first dielectric layer. The outer surface of the electrode and the electrically conductive layer define a gap.

It is an object of the present invention to provide an underwear capable of preventing a chest of a wearer from jiggling. The underwear according to the present invention comprises a pair of cup portions, a wire, and a wire length adjusting portion. The pair of cup portions protrude to a same side. The wire length adjusting portion is disposed between the foot of the pair of cup portions. Then, the wire extends from the opposite side of the wire length adjusting portion side of the cup portion to the wire length adjusting portion. The wire length adjusting portion can adjust a length L of the wire from the opposite side of the wire length adjusting portion side of the pair of cup portions to the wire length adjusting portion.
