Abstract: An assembly (10) includes a forward unit (12) including a mounting portion (16) for mounting thereon a firearm, the forward unit (12) defining a projectile shooting axis (20), and a rearward unit (14) coupled to the forward unit (12). The rearward unit (14) includes a retractable buttstock (24) that has a retracted position and an extended position. In the extended position the rearward unit (14) is pivotable with respect to the forward unit (12) about a pivot axis (26) which is tilted relative to the projectile shooting axis (20).

Abstract: One or more sensors may detect a gesture or gestures by one or more human users. The detected gesture or gestures may trigger sharing of music or other information. For instance, a first user may be listening to music on headphones. A second user may turn her head, so that her head is facing toward the first user. A sensor may detect this head orientation of the second user. This head orientation may trigger the system to share the first user's music with the second user, for at least as long as this head orientation continues.

Abstract: An assembly (10) includes a receiver body (12) that includes a butt (14), a body trigger (16), a grip (18), and a display screen (20). A variable-length shaft (24) extends from a front portion of the receiver body (12). A firearm receiver member (36) is coupled to a distal end of the variable-length shaft (24) by means of a coupling device (42), and a camera (40) is in communication with, and is configured to send images to, the display screen (20).

Abstract: One or more sensors may detect a gesture or gestures by one or more human users. The detected gesture or gestures may trigger sharing of music or other information. For instance, a first user may be listening to music on headphones. A second user may turn her head, so that her head is facing toward the first user. A sensor may detect this head orientation of the second user. This head orientation may trigger the system to share the first user's music with the second user, for at least as long as this head orientation continues.

Abstract: A double barrel adjustment assembly includes first and second barrel receiving members, each of which is formed with a bore for passing therethrough a barrel of a weapon. The first and second barrel receiving members are formed with complementary surfaces. The double barrel adjustment assembly further includes rotatable first and second adjustment members. One end of the first adjustment member is rotatingly mounted in the second barrel receiving member and an opposite end of the first adjustment member is rotatingly mounted in the first barrel receiving member. One end of the second adjustment member is rotatingly mounted in the first barrel receiving member and an opposite end of the second adjustment member is rotatingly mounted in the second barrel receiving member.

Abstract: The present invention provides for a composition, including: a sufficient first amount of a first active agent dispersion; where the first active agent dispersion has a pKa of 0.1-2.0, where the first active agent dispersion is selected from the group consisting of: an acid cation exchange resin, an acidic zeolite, an acidic clay, an organic acid, an inorganic acid, and any combination thereof, and where the first active agent dispersion includes a plurality of particles; where the plurality of particles has a median diameter of between 0.5-1000 micrometers; and a sufficient second amount of at least one chlorite salt dispersion; where, when the composition is contacted with an aqueous liquid, the sufficient first amount of the first active agent dispersion and the sufficient second amount of the at least one chlorite salt dispersion results in a generation of chlorine dioxide radicals.

Abstract: An early warning projectile penetration system includes a shoot house including a wall constructed of at least one inner layer of a ballistic penetration-resistant material, an outer layer of construction material, and a penetration detection system disposed intermediate the at least one inner layer and the outer layer. The penetration detection system is operative to provide an indication if a projectile has passed through the ballistic penetration-resistant material.

Abstract: A firearm accessory comprising at least one handle that may be attached to a firearm, the firearm comprising a butt and a barrel which define a plane, wherein a longitudinal axis of the firearm lies in the plane, wherein in a gripping position of the at least one handle, the at least one handle angularly extends away from the plane.
