Abstract: An optical platform assembly may include a head with a scan mirror; a body with an optical module to detect a hard body object; and a rotary connector that attaches the head to the body of the optical platform assembly. In some instances, the rotary connector may allow the head to rotate about the body, where the body is mounted and stationary to the surface. The optical body may be configured to detect for specific hard body objects, such as periscopes.

Abstract: Embodiments of the invention provide a removable memory unit (RMU) that facilitates concatenation of said memory modules irrespective of their individual physical interfaces, enables encryption/decryption keys (including cryptographic ignition keys (CIKs)) to reside onboard the RMU, provides for physical separation of RED and BLACK data in cross-domain environments and implements zeroization functionality onboard the RMU. Further embodiments provide a swappable IO backplane and adapter plates for incorporation into a wide variety of platforms.
