Another Navy document found that gives more detail on those 250 ActiPatches
Sounds like these are not standard ActiPatches. They will interface with the Circadian Positioning Systems equipment.
Statement of Requirements
ActiPatches
Operations Research Department
Naval Postgraduate School
1.0 Background/Introduction:
HEV light-blocking glasses and HEV-emitting devices could potentially be used onboard USN ships to control exposure to HEV light and help minimize circadian misalignment. With the exception of one study conducted at NPS, the utility of such method in the operational environment has not been assessed with empirical studies. The CPS actipatches will integrate with the CPS light emitting device, designed to simulate day and night to augment the system’s ability to facilitate circadian entrainment. As the US Navy faces revolutionary changes both in terms of watch schedules and the operational envelope, it is critical to find new and improved ways of supporting the sailor and facilitating operational readiness and optimal performance -- regardless of time of day or watchbill.
2.0 Minimal Technical Requirements/Salient Characteristics:
The ActiPatch must be validated for research purposes and meet the following requirements:
• Low profile, can be worn 24/7 and allow the flexibility to be worn on wrist and /or other parts of body
• Must be able to transfer data using a hard wired platform
• Sleep/wake scoring algorithm must be able to be modified to account for external motion
• Battery and memory capacity must be able to accommodate 21 days of data collection with no intervention
• Software must be able to transition between different sleep/wake algorithms post study
N6227119Q5015 05/06/2019 Page 2 of 4
• Must be compatible with the Circadian Positioning Lighting System
• Monitor skin temperature
• User-defined start-of-experiment and end-of-experiment dates to collect data within a given time period and to select the epoch length for data collection
• Resists dust, water, heat, perspiration and cold
• Measures activity with an on-board MEMS accelerometer
• Uses zero-crossing method to derive the activity values from raw acceleration data in real time
