A method for managing sleep of a user comprises obtaining, by a computing system, sleep data and environmental data for the user; determining, by the computing system, a sleep state of the user based on the sleep data; determining, by the computing system, one or more awakening actions based on the sleep state of the user and the environmental data; and causing one or more devices in an environment of the user to perform the one or more awakening actions to awaken the user.

A vehicle usage fee determination system includes a reception unit that receives a usage application by a user who has an intention to drive a vehicle, a wakefulness level estimation unit that estimates a wakefulness level of the user, and a fee determination unit that sets a usage fee of the vehicle when a target wakefulness level that is the wakefulness level at a time a first predetermined time before a scheduled driving start time of the vehicle by the user is a predetermined value to be equal to or less than a usage fee of the vehicle when the target wakefulness level is lower than the predetermined value.

Examples of the present subject matter provide techniques for measuring stress levels using a variety of physiological indicators, such as pupil diameter, voice, cortisol levels, skin resistance, etc. Different sensors may be provided to measure the physiological indicators. Those measurements may be collected at a central server, where those measurements may be analyzed to determine the stress level of the user.

A medical device for monitoring biological parameters through an Abreu Brain Thermal Tunnel (ABTT) is provided. By monitoring and analyzing the temperature of the ABTT, it is possible to diagnosis changes in a patient or subject under a variety of conditions, including predicting the course of medical conditions. Furthermore, since the ABTT is predictive, analysis of the ABTT may be used to control mechanisms for safety when an impending medical condition makes such operation hazardous.

A method of transplanting a sleep state of a first subject (donor) to a second subject (recipient) comprising: capturing a sleep state of the first subject represented by brain activity patterns; and transplanting the sleep state of the first subject in the second subject by inducing the brain activity patterns in the second subject.

A method and a system for providing feedback to a user for adjusting sleep pattern of the user. The method includes collecting a set of information related to the user, receiving a set of measurement data related to the user from a wearable electronic device, defining circadian rhythm and duration of sleep of the user, determining sleep scores for a predefined number of days and associating each sleep score with a corresponding go-to-bed time or time of falling asleep of the user. A sleep score is determined for each of the predefined number of days from the collected set of information, the set of measurement data, the circadian rhythm and the duration of sleep of the user. The method further includes analysing the sleep scores and associated go-to-bed time or time of falling asleep of the user to determine an optimum bedtime window for the user and providing feedback to the user based on the analysed sleep scores and the optimum bedtime window.

A mattress supports a left-side user and a right-side user. At least one acoustic sensor is configured to sense acoustic energy in the environment of the left-side user and of the right-side user. At least one pressure sensor is configured to sense pressure applied to the left-side portion by the left-side user and applied to the right-side portion by the right-side user. A controller is configured to receive at least one acoustic stream from the at least one acoustic sensor and at least one pressure stream from the at least one pressure sensor. Left-side snore/breath parameters and right-side snore/breath parameters are generated. The controller is further configured to, responsive to determining that a home automation rule includes a condition that includes at least one of the left-side snore/breath parameters and the right-side snore/breath parameters send an instruction to drive a controllable device to the controllable device.

An apparatus for monitoring a sleep parameter of a user includes an adhesive pad configured to conform to a surface of the user and a flexible element coupled to the adhesive pad. The flexible element includes a conductive fabric, and exhibits a modified electrical property in response to an applied force. The apparatus also includes a power source electrically coupled to the flexible element, and an electrical circuit electrically coupled to the power source and the flexible conductive element. The electrical circuit is configured to detect, during use, a change in an electrical property of the flexible element.

According to an aspect of the invention there is provided a system for use in monitoring one or more physiological states of a user, the system comprising one or more processors configured to: receive a pressure signal representing pressure within a cushioning layer supporting at least a portion of a user and an acoustic signal representing acoustic vibrations within the cushioning layer; and determine, based on the pressure signal and acoustic signal, the one or more physiological states of the user.

Embodiments provide physiological measurement systems, devices and methods for continuous health and fitness monitoring. A wearable strap may detect reflected light from a user's skin, where data corresponding to the reflected light is used to automatically and continually determine a heart rate of the user. The wearable strap may monitor heart rate data including heart rate variability, resting heart rate, and sleep quality. The systems may include a processing module that generates an indicator of physical recovery based on the heart rate data. The recovery indicator may be used to determine strain related to an exercise routine, qualitative information on the user's health, whether to alter a user's exercise plan, and so forth.
