Abstract: A skin incision device has a casing with a bottom surface and a slot formed therein, a cover positioned on the casing and slidable in a direction toward the bottom surface, a blade positioned in the casing adjacent the slot, an actuator cooperative to a position between the cover and interior of the casing, and a carriage. The actuator engages the blade by its horizontal displacement triggered by slidable movement of the cover toward the bottom surface of the casing. The carriage element guides movement of the blade between a pre-actuated position and a post-actuated position. The blade extends outwardly of the bottom surface with a fixed depth of cut during a horizontal movement of the blade through the slot.

The actuator engages the blade by its horizontal displacement triggered by the slidable movement of the cover toward the bottom surface of the casing. The carriage element guides the movement of the blade between a pre-actuated position and a post-actuated position. The blade moves outwardly through the slot, cuts with a horizontal movement, and returns inwardly through the slot.

Abstract: There is provided an autonomous off-board defensive aids system (100) for use with a host craft (102), for example, with combat aircraft or submarines. More particularly, the host craft (102) deploys a plurality of controllable off-board units (104, 106) to counter an offensive threat or to engage in autonomous offensive actions. The controllable off-board units (104, 106) implement active stealth facilities: each off-board unit (104, 106) having a receiver unit for detecting impinging detection pulses, for example radar or sonar pulses, and a transmitter unit for generating an artificial detection pulse profile, for example “spoofing” or masking the presence of the host craft. The controllable off-board units are of two types: tethered (104) and free moving (106). The off-board units (104, 106) can have conventional propulsion apparatus, for instance, propellers, rockets or jets. Off-board units (104, 106) each have control apparatus which allows the off-board units (104, 106) to co-operate.
