Personnel High Rate Data Recorder

To improve protection for military personnel, exposure to potential injury needs to be recorded. Typically such environments occur during realistic training and operations where harsh environments such as blast or impulse noise create unique challenges to the collection of high-quality data. Existing methods using umbilical cabling or wires, heavy/bulky equipment and/or close-range wireless transmission require prediction or the control of personnel activities and are not practical in training and mission operations. There is no existing design that can record high quality data from an entire event that occurs at an unknown time and place during training or mission operations. Following a successful Phase I demonstration of at least three channels at 1 MHz sampling per channel, the overall objective of the Phase II effort is to design, build and test prototype and pre-production units that can be used in laboratory and field testing. The design should be small, lightweight, low power, robust, modular, with sufficient memory to record ten complete time-series events of at least 1 second and wearable without interfering with safety. The proposed architecture will allow the addition of three-channel modules and interconnecting multiple systems to further expand the channel count.
