Remote Waking System Using Adaptive Stimuli Sequences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments where teams alternate between on-duty and off-duty status, such as long-haul flights, there is a need for an effective system to wake off-duty personnel without impairing their cognitive abilities, especially during emergencies when immediate recall is necessary.
Innovation Solution
A system comprising sensors and waking stimulus sources, processed by a system that determines the optimal stimuli and sequence for waking based on sleep and cognitive states, using visual, aural, and vibrational stimuli, and adjusting according to environmental and emergency conditions.

Engineering Contradiction Analysis
1Speed
If abrupt awakening methods are used to ensure immediate recall during emergencies, then response time is reduced, but cognitive abilities are impaired
Solution Approach 1:
The system applies periodic action by delivering awakening stimuli in a structured sequence rather than a single abrupt stimulus. Multiple stimuli are delivered at different time intervals, allowing the person to gradually transition from sleep to full alertness while maintaining the capability for rapid response when needed.
Solution Approach 2:
The system performs preliminary action by preparing the awakening process in advance through a predetermined sequence of stimuli. The first stimulus is delivered gently to begin the transition, and subsequent stimuli are prepared and delivered in sequence, allowing cognitive functions to activate progressively before full duty engagement is required.
2Reliability
If multiple stimuli are used to ensure effective awakening, then awakening reliability is improved, but system complexity increases
Solution Approach 1:
The system segments the awakening process into distinct stages, each with specific stimuli types and delivery parameters. The awakening sequence is divided into multiple discrete steps (first stimulus, second stimulus, etc.), allowing each component to be independently controlled and optimized while maintaining overall system manageability.
Solution Approach 2:
The system implements dynamics by making the stimulus delivery adaptive and adjustable. The timing, type, and intensity of stimuli can be modified based on the person's response and specific operational requirements, allowing the system to optimize awakening effectiveness without requiring a fixed complex mechanism for every scenario.

AI summary
A system and method of waking a person includes receiving, in a processing system, stimuli configuration data that is indicative of all available waking stimuli available for use. Sleep state data that is indicative of a current sleep state of the person is received in the processing system. The stimuli configuration data and the sleep state data are processed, in the processing system, to determine (i) a set of the available stimuli to use to awaken the person and (ii) a sequence of activation of the set available stimuli to use. The set of available stimuli are selectively activated, via the processing system, in the determined sequence of activation.
