Abstract: A portable shooting bench configurable in a stowed configuration and a deployed configuration. In the deployed configuration, the shooting bench can be adjusted to accommodate a right-handed shooter or a left-handed shooter. Other adjustment capability is provided. The shooting bench is relatively lightweight. In the stowed configuration, the shooting bench is relatively compact to facilitate transportation and storage.

Abstract: A shooting rest and associated methods. The shooting rest includes a forward support and a rear support both supported by a frame. The forward support is configured to clamp a forward portion of the firearm and permit rotation of the firearm with respect to the frame about a pitch axis to adjust a vertical aim of the firearm and about a yaw axis to adjust a horizontal aim of the firearm. The rear support includes a platform positioned to support a bottom of a trigger hand grip portion of the firearm. The platform is adjustable in elevation to adjust the vertical aim of the firearm.

Abstract: An ammunition case primer pocket swager and associated methods. An actuator of the primer pocket swager may be operatively connected to a swage head for driving the swage head to a swaging position to swage the primer pocket, and may be operatively connected to a case holder for moving the case holder from a loading position to an operational position to hold the case to be swaged. Lost motion in a drive train of the primer pocket swager can be used to position the case holder in the operational position before the swage head reaches the swaging position. A primer pocket swager can include an adjustable case holder stop, a pivot mount guide, and/or a case aligner.

Abstract: A tie down stake and associated methods. The tie down stake is configured to mount on a second tie down stake in a storage configuration. Multiple tie down stakes can be chained to each other by releasable mounting connections formed by adjacent tie down stakes in the chain.

Abstract: A cartridge case catcher and associated methods. The cartridge case catcher is configured to catch cartridges ejected from an action of a firearm. The cartridge case catcher includes a mount for mounting to the firearm. The cartridge case catcher includes a receptacle having a case compartment sized for carrying cases ejected from the action. A mouth of the catcher provides access to the case compartment. A pivot connection connects the receptacle to the mount. The receptacle is movable with respect to the mount about the pivot connection between an operational orientation to receive cases ejected from the firearm action and an access orientation in which the receptacle permits access to the action of the firearm.

Abstract: A stuck shell remover and associated methods. The stuck shell remover is mountable on an ammunition press. The stuck shell remover includes a clamp that is clampable on a shell stuck in a die on the ammunition press. When the clamp is clamped on the stuck shell, the ammunition press can be actuated to pull the suck shell out of the die. The stuck shell remover may include a press connector that is movable with respect to the clamp to permit proper alignment.

Abstract: A method includes receiving data corresponding to a sequence of deformations of a surface of an object. The method also includes generating spherical harmonics expressions based on the data. The method includes identifying a subspace of the spherical harmonics expression corresponding to the surface.

Abstract: A sheath and a method of operating the sheath are provided for assisting movement of an endoscope within a cavity of a patient's body. The sheath includes an everting shaft having an internal and external lining with an inflatable lumen between them, proximal and distal regions and a lumen for receiving the endoscope. An expandable member is positioned along the distal region, which is expandable from a first diameter, at which the expandable member grips the endoscope to a second, larger diameter at which the expandable member engages a wall of the cavity.
