Determining low power frequency range information from spectral data. Raw signal data can be adjusted to increase dynamic range for power within low power frequency ranges as compared to higher-power frequency ranges to determine adjusted source data valuable for acquiring low power frequency range information. Low power frequency range information can be used in the analysis of a variety of raw signal data. For example, low power frequency range information within electroencephalography data for a subject from a period of sleep can be used to determine sleep states. Similarly, automated full-frequency spectral electroencephalography signal analysis can be useful for customized analysis including assessing sleep quality, detecting pathological conditions, and determining the effect of medication on sleep states.

Knitting machines are used to intermesh conductive yarns into loops resulting in knitted fabrics. The knitting machine is adapted to import different types of yarns (conductive and non-conductive) directly into the knit structure. Combining conductive yarns and knitting systems allows for integration of electrical or mechanical component designs into existing clothing fabrication processes, avoiding current limitations of attaching or gluing conductive fabrics or other components over various materials. Starting with a planar design of an antenna, RFID tag, or some other electronic structure, the layout is converted into a CAD knitting program including a grid representing stitches. The CAD specifications of the final design/product are exported to the knitting machines so that the knitting machine may make conductive fabrics in accordance with the CAD specifications. The conductive fabrics are knitted into a variety of garments that monitor the vital signs of the wearer, including the fetus of an expectant mother.

Valence states comprise physical states associated with emotional reaction to one or more events. Users may want to alter their reaction during such valence states (improve performance, reduce stress or anxiety, etc.). Physiological responses of a user wearing a valence state monitor may be recorded during waking life. When a physiological response associated with a valence state is determined, the valence state monitor may produce one or more cues comprising sounds, lights, haptic feedback, and/or electric shock, etc. During sleep, physiological responses of the may be used to determine the user is entering a dream phase (REM or N2) and, during such periods the cue and/or additional cues may be administered such that the user's memory is triggered to prime an associative thought of the valence experience while dreaming. By priming an associative thought during sleep, the user may better work through and adapt to various valence experiences while awake. 1. A valence monitoring device comprising:one or more sensors;one or more processors; andone or more non-transitory computer readable media having instructions stored thereon which, when executed by the one or more processors cause the one or more processors to perform operations comprising:receiving, from the one or more sensors at a first time, first sensor data;determining that a user wearing the valence monitoring device is in a valence state, the valence state indicative of the user having a heightened emotional response to an event;causing, based at least in part on the user being in the valence state, one or more transducers to produce a first cue;receiving, from the one or more sensors at a second time, second sensor data;determining, based at least in part on the second sensor data, that the user is in one or more of a REM phase or an N2 phase of sleep;causing, based at least in part on determining that the user is in one or more of the REM phase or N2 phase, the one or more transducers to produce the first ...
