Abstract: A system for reducing concussions in a sport participant. The system includes a helmet, the helmet comprising a shell having a crown region; a first tether, the first tether having a first end and a second end, the first end connected to the crown region of the shell of the helmet; and a uniform comprising a waist band and/or belt, the second end of the first tether connected thereto, the first tether having a slack region, wherein the momentum of the first tether upon matching the momentum of the sport participant eliminates the slack region of the first tether and restrains the helmet of the sport participant, reducing the chance of receiving a concussion. A method for reducing concussions in a sport participant is also provided.

Abstract: An autonomous vehicle having a tether therein attached to at least one end thereof to a first point in the autonomous vehicle and at the other end thereof to a second and different point in the autonomous vehicle. The tether includes a slack region having a slack so that when the slack changes position due to a change in momentum of the moving autonomous vehicle, the tether acts on the second and different point attachment to stop the autonomous vehicle. Also provided is a method for stopping an autonomous vehicle. The method includes providing a tether, at least one end thereof attached to a first point in the autonomous vehicle, the other end thereof attached to a second and different point in the autonomous vehicle, wherein the tether includes a slack region having a slack so that when the slack changes position due to a change in momentum of the moving autonomous vehicle, the tether acts on the second and different point attachment to stop the autonomous vehicle.

Abstract: A pad of a plurality of sealable-unsealable bags comprising a stack of the bags, each bag comprising a front and rear wall closed at the sides and bottom and having a region of access to between the walls; a closure flap as an integral extension of the back wall, the flap having an inside and an outside surface relative to the bag in its sealed condition; an adhesive region located on a portion of the inside surface of the flap; and at least the adhesive-bearing portion of said flap being reverse-folded, outside surface-to-outside surface and the adhesive-bearing inside surface positioned in releasable adhesive contact with a non-adhesive bearing portion of the inside surface of the flap of a preceding bag in the stack.

Abstract: Apparatus for assessing maneuvers of a first vehicle (6) so fitted relative to other vehicles (58, 68, 71-74) comprises sensing means for providing signals representative of the positions and velocities of the other vehicles relative to the first vehicle (6), computing means responsive to said signals for computing symbology respectively associated with the other vehicles, and display means coupled to the computing means for displaying the symbology relative to the position of the first vehicle, thereby providing indicia to assess maneuvers of the first vehicle which will avoid collision with the other vehicles, and which will ensure that the first vehicle will not pass closer to the other vehicles than a predetermined distance for all relative positions and velocities thereof, the symbology associated with each of the other vehicles in all encounter circumstances comprises at least a final escape point (FEP) (40) which, if reached by the first vehicle (6), will allow the first vehicle still to avoid the asso

Abstract: Collision avoidance apparatus for assessing manoeuvres of a first vehicle (6) to avoid collision with other vehicles (22) in which closed regions are computed respectively associated with the other vehicles and which, if avoided by the first vehicle, will assure that the latter will not pass closer to the other vehicles than a predetermined distance (CPA).

Abstract: The invention is a radar harbor surveillance sensor, computer, and display system for providing a graphic display of vessels negotiating confined navigation channels and permitting rapid and accurate assessment of the degree of hazard or safety in the movements of the monitored vessels.
