Abstract: A situational-awareness accessory comprises a housing including a control board, a user display, and a visual sensor for receiving electromagnetic radiation that is invisible to the human eye from a wide-angle, optical field-of-view in front of the visual sensor. The control board converts the received electromagnetic radiation into visual display data and initiates display of the visual display data on the user display. A quick-detach accessory base mount coupled with the housing permits attachment of the housing to an accessory rail.

Abstract: The present disclosure describes methods and systems for measuring crosswind speed by optical measurement of laser scintillation. One method includes projecting radiation into a medium, receiving, over time, with a photodetector receiver, a plurality of scintillation patterns of scattered radiation, comparing cumulative a radiation intensity for each received scintillation pattern of the received plurality of scintillation patterns, and measuring a cumulative weighted average cross-movement within the medium using the compared cumulative radiation intensities.

Abstract: In some aspects a quick-detach (QD) accessory base mount includes a body. The body includes an accessory engagement interface configured to engage an accessory and a rail engagement interface defining a channel adapted to receive an accessory rail. A rail clamp is carried by the body and is moveable to selectively clamp the body to the accessory rail. A mounting arm extends outwardly from the body and is carried to rotate relative to the body between a first position and a second position. A cam is configured to support the rail clamp to grip the accessory rail and to clamp the body to the accessory rail when the mounting arm is in the first position and to release the rail clamp from gripping the accessory rail when the mounting arm is in the second position.

Abstract: In some implementations a mountable afocal adaptor for a camera includes an attachment plate affixed to the front of a camera housing of a camera and an afocal optical module. The afocal optical module is configured to convert a received optical image to a converted optical image for use by the camera. The afocal adaptor also includes a rotation mechanism with a rotation ring and a wave spring clamp, the rotation ring affixed to the attachment plate and the wave spring clamp affixed to the afocal optical module. The rotation ring and wave spring clamp are mounted relative to each other to rotate around a rotational axis aligned with an axis of an optical path formed between the afocal optical module and the attachment plate and aligned with a view axis of the camera. The rotation mechanism also permits rotation of the camera housing around the rotational axis relative to the afocal optical module.

Abstract: The present disclosure describes structures, methods, and functionality for measuring a wind profile with networked anemometers. One method includes receiving real-time wind measurement data from each of one or more anemometer sensor platforms (ASPs) in a network, receiving atmospheric data, and calculating, using the received real-time wind measurement data and the received atmospheric data, at least one of real-time wind measurements, a wind profile, an average wind speed, or a weapon aiming offset.
