Current US Army issued binoculars lack the digital capabilities of today’s electro-optic devices. By linking traditional optical binoculars with a smartphone, users can take advantage of the smartphone’s digital camera. Live images viewed through the binocular can be captured as an image or recorded as video in real time. Additional capabilities of the Smartphone can be utilized such as, digital zoom on top of the binoculars optical magnification, GPS for geo-tagging information, wireless communication for transmission of recorded data, etc. The linking of Commercial Off-The-Shelf (COTS) smartphones with optical based binoculars has shown enormous potential including persistent ISR capability. The paper discusses the demonstration, results and lessons learned of B-LINK-S applications.

The Early Attack Reaction Sensor (EARS) is a modified passive acoustic system that detects gunshots (muzzle blast and/or shockwave) to provide the user with relative azimuth and range of sniper fire via both audio alert and visual display. The EARS system consists of a microphone array in a small planar configuration and an equivalently sized Digital Signal Processing board, which is interfaced to a PDA via a PCMCIA slot. Hence, configuration easily provides portability. However, the system is being repackaged for man-wearable and vehicle mount applications. The EARS system in a PDA configuration has been tested in open fields at up to 500 meters range and has provided useable bearing and range information against the sniper rounds. This paper will discuss EARS system description, various test results, and EARS system capabilities and limitations.
