Abstract: A door breaching robotic manipulator comprises: two fingers, each finger comprising a gripper surface at a distal end thereof, the gripper surfaces being spaced from each other by a predetermined distance; a cable configured to be actuated to drive the gripper surfaces toward each other; and a selectively compliant wrist comprising a U-joint and a magnetic coupling having a predetermined magnetic force strength. The magnetic coupling comprises a metal member and a magnetic element attracted thereto. When a force overcomes the predetermined magnetic force strength of the selectively compliant wrist, the wrist becomes compliant.

Abstract: A miniature rotating transmissive optical scanner system employs a drum of small size having an interior defined by a circumferential wall rotatable on a drum axis, an optical element positioned within the interior of the drum, and a light-transmissive lens aperture provided at an angular position in the circumferential wall of the drum for scanning a light beam to or from the optical element in the drum along a beam azimuth angle as the drum is rotated. The miniature optical drum scanner configuration obtains a wide scanning field-of-view (FOV) and large effective aperture is achieved within a physically small size.
