Claims18
A time limited restraint device, comprising:
- an elongated and flexible restraint member that is formed as an annular member of a desired circumference by sliding an end of said restraint member through an attachment member of said restraint member in a first direction, whereupon the direction of sliding of said first end relative to the attachment member may not be reversed manually, as said attachment member grasps said restraint member and holds the restraint member in position upon reversal of direction of sliding of said restraint member from said first direction,
- a cutter that is positioned in proximity to said restraint member, a timer, and
- an actuator that forces said cutter against said restraint member upon receiving a signal from said timer, whereupon said cutter severs said restraint member.
A time limited restraint device, comprising:
- an elongated and flexible restraint member that is formed as an annular member,
- a slidable cutter comprising a blade on an end thereof, wherein said blade is positioned proximally to said restraint member,
- a timer, and
- an electrically actuated explosive charge that, upon receiving an electrical signal initiated by said timer, explodes said explosive charge and advances said slidable cutter to slide against and through said restraint member upon receiving a signal from said timer, whereupon said blade of said cutter severs said restraint member as said cutter slides against and through said restraint member.
