Introduced are methods and systems for an adjustable bed device configured to: gather biological signals associated with multiple users, such as heart rate, respiration rate, or temperature; analyze the gathered human biological signals; and heat or cool a bed based on the analysis.

A signal processing system includes a heartbeat information acquisition unit, a representative value calculation unit, and a nerve recognition unit. The heartbeat information acquisition unit acquires, from a radio wave sensor, heartbeat information as a result of detection of a person's heartbeat. The representative value calculation unit calculates, based on the heartbeat information, a representative value of an interval of the heartbeat during a predetermined period. The nerve recognition unit recognizes, based on the representative value, a condition of the person's autonomic nervous system.

Methods, systems, and devices are provided for generating a mist. In one embodiment, a fluid delivery device is provided that includes a housing, a fluid vaporizer disposed within the housing and configured to receive fluid and to produce an aerosol mist of liquid particles from the fluid, and a pump configured to accelerate the aerosol mist produced by the fluid vaporizer. Methods are provided for producing a mist, and the methods can include delivering a fluid to a fluid vaporizer that generates a first mist. The fluid vaporizer delivers the mist to a pump that generates a second mist from the first mist.

A bed covering system adapted to be used by a user to stay comfortable during sleep. The bed covering system includes a blanket and a pillowcase. The blanket has different heat retention zones of at least one section of heavy material and at least one section of lighter material. The heavy material is of material that retains body heat of the user. The lighter material is of a material that allows the escape of body heat of the user and allows circulation of body heat of the user. The heavy material has a higher weave count to trap and retain heat, and the lighter material is of thinner materials that permits more evaporation from a body of a user than the heavy material.

An arousal level prediction apparatus and method are disclosed. The arousal level prediction apparatus obtains first biological information indicating current biological information of the user, obtains first environment information indicating a current environment around the user, and obtains living information of the user indicating an activity history of the user. The arousal level predication apparatus includes a process that calculates a first arousal level indicating a current arousal level of the user based on the first biological information, predicts a second arousal level, which is an arousal level of the user at a certain period of time later, based on the first arousal level, the first environment information and the living information, and outputs the second arousal level.

Configurations are disclosed for a health system to be used in various healthcare applications, e.g., for patient diagnostics, monitoring, and/or therapy. The health system may comprise a light generation module to transmit light or an image to a user, one or more sensors to detect a physiological parameter of the user’s body, including their eyes, and processing circuitry to analyze an input received in response to the presented images to determine one or more health conditions or defects.

The present invention provides systems, methods, and articles for stress reduction and sleep promotion. A stress reduction and sleep promotion system includes at least one remote device, at least one body sensor, and at least one remote server. In other embodiments, the stress reduction and sleep promotion system includes machine learning.

A sleep system may include a control system for a bed device that includes platform upon which an individual may be supported. The sleep system may include multiple input sources that trigger combinational output action patterns with respect to the control system and bed device. The multiple input sources may include sensors positioned to collect input data with respect to the subject, bed device, and/or surrounding environment such as motion sensors, presence sensors, proximity sensors, sound sensors, temperature sensors, biological sensors, and/or light sensors.

Described are systems, devices and methods that use vestibular stimulation to control and improve sleep. The systems, devices and methods described herein are the first to use either one or more than one method of vestibular stimulation from a plurality of different vestibular stimulations (e.g., electrical, thermal, acoustic, optical or tactile) to create illusory motions for affecting sleep. The described systems and methods are the first to utilize an algorithm to determine which stimulation technique to use, when to use a particular stimulation technique, and the unique characteristics to include in the stimulation technique.

Various implementations include a wearable stress-reducing system. The system includes one or more sensors, a stimulating device, and a control system. The sensors are configured to each measure at least one indicator of stress from a user. The stimulating device is configured to provide a stress-reducing stimulation to a portion of user's skin. The control system includes a controller that includes a logic processor that is configured to receive at least a stress indicator measurement from the sensors, compare the stress indicator measurement to a predetermined threshold, determine whether to modify the stress-reducing stimulation based on comparing the stress indicator measurement to the predetermined threshold, and, if a modification is needed, transmit an instruction to adjust the stress-reducing stimulation provided by the stimulating device. The stimulating device adjusts the stress-reducing stimulation enough to lower the at least one indicator of stress below the predetermined threshold.
