Abstract: The disclosure is premised on the realization that despite the apparent convenience, safety and effectiveness possible by use of a less-lethal weapon incorporated into the foregrip of a two-handed weapon, no major police department, government agency, or military unit deploys such a system. This deficiency can be remedied by the disclosed device, which comprises a less-lethal weapon system that employs industry-standard components, and is effective and easy to use. The disclosed invention mounts a standard-size incapacitant canister in the handgrip portion of a foregrip. The foregrip is secured to the firearm by a standard rail system, and uses standard trigger and safety configurations. The canister magazine allows for efficient loading and reloading of the incapacitant, and the canister mounting angle allows for effective use. Further, some embodiments of the invention may include an accessory mounting area in which a tactical flashlight or laser may be mounted.

Abstract: A sports swing trainer includes a gripping portion configured to enable a user to grasp the trainer while in a batting stance, an arm positioning portion, and an alignment portion connecting the other two portions together. The arm positioning portion includes parts that simultaneously engage with a top of the shoulder and a brachium of the user when in a proper batting stance, and the arm positioning portion provides tactile feedback reminding the user to begin a swinging motion with hip and leg movements rather than arm movements. The alignment portion may include one or more joints that enable custom positioning of the gripping portion and the arm positioning portion to suit the training needs of many different users. The sports swing trainer provides an easy to manufacture solution for baseball/softball bat swing training which focuses on the mechanics of the swing rather than ball placement and contact.

Abstract: A coated print bed for a 3D printer having a permanent print-surface coating permanently secured to a print bed substrate plate, having a smooth, planar surface that provides an adhesive interface layer between a first layer of an applied plastic print material and the coated print bed. The coating contains a matrix-forming compound, such as a solvent- or water-based epoxy resin, an adhesive material, and optionally a filler. The user can print a series of print object directly onto the permanent print surface coating of the coated print bed, without having to refresh or refurbish the print surface, such as by applying to the print bed surface a temporary coating such as painter's tape, or a liquid adhesive.
