Fatigue monitoring and management system

Abstract: A system monitors fatigue of a user. The system (100) may include one or more data sources, such as a non-obtrusive sleep sensor, configured to generate objective sleep measures of the user. The system may also include a fatigue monitoring module, which may be configured to generate an assessment, such as in one or more processors, of the fatigue state of the user based on the data from the one or more data sources.

System and method for manipulating sleep architecture by sub-awakening non-intrusive stimulations

Abstract: The present invention which is a new system and method employing stimulation control to treat sleep disorders, and improve sleep states operates in a dynamic, adaptable manner without causing a premature state of arousal. Stimulation is achieved by controlling a wide variety of environmental factors around the sleeping person. The invention is based on a real-time, self-adaptive feedback system including a sleep and environment monitoring unit or a preset adjustable protocol, an integrating, controlling and deciding unit and a stimulation unit. The system and method take into account individual variability and sensitivity to sensory stimulation and phenomena as adaptation and sensitization. The system and method are aimed at improving the overall sleep architecture, and correcting specific disorders. Alternatively the same invention may be used to promote alertness, specific moods and conditions in the awake subject. The invention may be used by professional in sleep laboratories or by individuals in a home environment. It may be adjusted to operate on groups of people and on non-human subjects.

Human sleep monitoring method and system

Abstract: The invention relates to a human sleep monitoring method and system. The method and system synthesizes motion, heart rate and body temperature signals. The system comprises a core processor, a reflective type photoelectric pulse sensor, a temperature sensor, a three-axis gravity acceleration sensor and a capacitive skin contact sensor which are respectively used for measuring heart rate in real time, measuring body surface temperature in real time, detecting motion state in real time, and performing wearing identification. The human sleep monitoring system has the advantages that by synthesizing human body sign information and motion states, the system can automatically monitor the sleep state and the waking state of a user and can identify different sleep stages including shallow sleep, deep sleep and rapid-eye-movement sleep; the system further comprises a display module and a miniature motor vibrating module which are used for displaying specific sleep information and awakening the user on the basis of sleep quality; the problems that an existing sleep monitoring device cannot naturally awaken the user at an appropriate time, physical and mental health of the user is affected, and the existing sleep monitoring device is inconvenient to use are solved.

Apparatus for the treatment of sleep apnea

Abstract: The invention concerns a medical device for implantation in a body, comprising a stimulation unit, a sleep detector unit having at least one signal input which is adapted to detect a sleep condition of the body and to produce a sleep signal, an apnea detector unit which is adapted to detect sleep apnea in dependence on at least one body signal caused by the body and to produce an apnea signal, a therapy unit which is at least indirectly connected to the stimulation unit! the sleep detector unit and to the apnea detector unit and which is adapted to produce, in dependence on the apnea signal and the sleep signal, at least one apnea therapy signal which represents therapy information for preventing and/or for the treatment of sleep apnea, and to send same to the stimulation unit. The medical device has a position sensor, which is operatively connected to the signal input of the sleep detector unit and adapted in dependence on its inclination about at least one spatial axis extending through the position sensor in relation to the horizontal to alter at least one of its electrical properties.

System and method for providing sleep quality feedback

Abstract: A system and method for providing sleep quality feedback that includes receiving alarm input on a base device from a user; the base device communicating an alarm setting based on the alarm input to an individual sleep device; the individual sleep device collecting sleep data based on activity input of a user; the individual sleep device communicating sleep data to the base device; the base device calculating sleep quality feedback from the sleep data; communicating sleep quality feedback to a user; and the individual sleep device activating an alarm, wherein activating the alarm includes generating tactile feedback to the user according to the alarm setting.
