A processing device in one embodiment is configured to generate a first sound cue of a first type, the first sound cue comprising a primary entrainment cue for an entrainment sonification system, to generate one or more additional sound cues of a second type, each of the one or more additional sound cues comprising an auxiliary entrainment cue for the entrainment sonification system, to provide the first sound cue and the one or more additional sound cues to one or more audio devices of the entrainment sonification system for generation of sound for audible presentation to a user, to receive from one or more sensors of the entrainment sonification system one or more feedback signals, and to adjust one or more characteristics of at least one of the first sound cue and the one or more additional sound cues based at least in part on the one or more received feedback signals.

Techniques related to temporary setpoint values are disclosed. The techniques may involve causing operation of a fluid delivery device in a closed-loop mode for automatically delivering fluid based on a difference between a first setpoint value and an analyte concentration value during operation of the fluid delivery device in the closed-loop mode. Additionally, the techniques may involve obtaining a second setpoint value. The second setpoint value may be a temporary setpoint value to be used for a period of time to regulate fluid delivery, and the second setpoint value may be greater than the first setpoint value. The techniques may further involve causing operation of the fluid delivery device for automatically reducing fluid delivery for the period of time based on the second setpoint value.

Described herein is the use of CSF, more particularly external CSF or CSF-like compositions for the treatment and prevention of different diseases. More particularly, the application provides for the administration of CSF to the intrathecal space or the cerebral ventricles of a patient to increase intracranial pressure and/or CSF flow.

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 methods, systems and devices provided herein relate to sleep-aid. Some embodiments include a vibration source and/or a sound source. In some embodiments, the vibration source and/or sound source emit vibrations and/or sounds that stimulate a subject's vagus nerve, or another nerve, to induce sleep or relaxation in the subject.

Methods and systems are provided for delivering anesthetic agent to a patient. In one embodiment, an anesthetic vaporizer includes a sump configured to hold a liquid anesthetic agent; an ultrasonic transducer coupled to a bottom of the sump and at least partially disposed within the sump; a vaporizing chamber fluidically coupled to the sump; and a heating element coupled to the vaporizing chamber and configured to increase a temperature of a surface disposed within the vaporizing chamber.
