Abstract: A release mechanism for separating two components including: (i) a first plate-shaped member (1) with a first midplane (21) that is connectable to a first component and having two opposite first surfaces (3; 3?) arranged parallel to the first midplane and a first coupling portion (5); (ii) a second plate-shaped member (2) with a second midplane (22) that is connectable to a second component and having two opposite second surfaces (4; 4?) arranged parallel to the second midplane and a second coupling portion (6); (iii) an explosive (9) arranged in the first coupling portion and/or the second coupling portion or between them; and (iv) a plurality of protrusions (10) provided on and firmly connected to at least one of the first surfaces and/or the second surfaces. The first member and the second member are coupled to each other in a mutual midplane comprising the first midplane and the second midplane.

Abstract: The invention relates to a sterile surgical drape comprising a cover portion for a tracking reference array, wherein at least a part of the cover portion is formed inherently stable and has a form adapted to accommodate multiple tracking markers of a tracking reference array for computer-assisted surgery. Further, it relates to a surgical draping system and a medical navigation method using such a drape.

Abstract: Warhead (1) comprising a tubular structure comprising: a front end (15) and a front region (2) adjoining the front end (15); a rear end (14) and a rear region (3) adjoining the rear end (14); a central axis (11) connecting the front end (15) and the rear end (14); a wall portion (4); and a central cavity (6), whereby the outer wall portion (4) tapers in the front region (2) and comprises fragments (7; 9) in the rear region (3) and the tubular structure in the rear region (3) comprises a generally cylindrical portion (12) and a generally conical portion (13) relative to the central axis.

Abstract: Fragmentation sleeve (1), for a generally circular cylindrically shaped ammunition body (2), whereby the sleeve (1) has an annular shape with an inner diameter at no place smaller than the outer diameter of the ammunition body (2), an outer diameter Da, an internal surface Si, an external surface Sa, and a height H, the sleeve is configured to be slid over and positioned on an outer surface (3) of the ammunition body (2) and comprises a plurality of fragments (4) embedded in a polymeric matrix (5).

Abstract: A low-speed projectile is designed for forming relatively large apertures in walls against which the projectile is fired. The projectile includes a penetrator core having a cavity containing an explosive charge activated by a time delay fuse circuit. The time delay is chosen to cause explosive ignition when the cavity and explosive is within the wall to be pierced. The construction of the projectile directs the explosive impulse radially, creating a hole in the wall considerably larger than the outside diameter of the penetrator's core. A preferred application is a projectile for a shoulder-fired weapon.
