Technical Examples
- Devices and methods for sleep detection involve the use of an adjustable threshold for detecting sleep onset and termination. A method for detecting sleep includes adjusting a sleep threshold associated with a first sleep-related signal using a second sleep-related signal. The first sleep-related signal is compared to the adjusted threshold and sleep is detected based on the comparison. The sleep-related signals may be derived from implantable or external sensors. Additional sleep-related signals may be used to confirm the sleep condition. A sleep detector device implementing a sleep detection method may be a component of an implantable pulse generator such as a pacemaker or defibrillator.
- A sleep efficiency monitor and methods for pacing and leading a sleeper through an optimal sleep pattern. Embodiments of the present invention include a physiological characteristic monitor for monitoring the sleep stages of a sleeper, a sensory stimulus generator for generating stimulus to affect the sleep stages of a sleeper, and a processor for determining what sleep stage the sleeper is in and what sensory stimulus is needed to cause the sleeper to move to another sleep stage. A personalized sleep profile may also be established for the sleeper and sleep guided in accordance with the profile parameters to optimize a sleep session. By providing sensory stimulus to a sleeper, the sleeper may be guided through the various sleep stages in an optimal pattern so that the sleeper awakens refreshed even if sleep is disrupted during the night or the sleeper's allotted sleep period is different than usual. Embodiments of the invention also involve calibration of the sleep guidance system to a particular sleeper.
- A variable speed air handling system for cooling and/or heating a room including a sleep mode. The system includes a fan assembly to transport air from the system into the room, the fan assembly having a substantially continuously adjustable speed within a range of speeds defined by a predetermined upper limit and a predetermined lower limit. A user interface transmits a sleep mode signal upon activation of the sleep mode by a user. A control unit controls the fan assembly and the climate control unit to gradually raise an ambient temperature in the room over a predetermined period of time in response to the sleep mode signal transmitted by the user interface.
- Systems and methods for evaluating the effectiveness of a person to perform a task based on his/her preceding or predicted sleep pattern are provided. An interface allows a user to use actual sleep data or predicted sleep data to produce predictions of the task effectiveness of a person to perform a particular task. The predictions may be in tabular, graphical, or tabular and graphical format. The interface may also represent the effectiveness of a user based on the actual or predicted sleep data in conjunction with an actual or predicted work schedule or pattern. The results can be correlated to sunlight in the user's location, and can also account for changes in the users location (transmeridian shifts), sunlight during the user's sleep cycle (shift work), and other schedule modifying events.
- An implantable cardiac device is programmed to differentiate between central sleep apnea and obstructive sleep apnea. The implantable cardiac device utilizes a respiration-related parameter (e.g., respiration rate, tidal volume, and minute ventilation) to determine whether the patient is experiencing an episode of sleep apnea. When sleep apnea is detected, the implantable cardiac device examines the intracardiac electrogram (IEGM) to classify the apnea as either central sleep apnea or obstructive sleep apnea. The cardiac device may be further configured to administer different therapies depending upon the classification of sleep apnea.
