US12687366 - Cleaning apparatus for sealed firearm suppressor

A cleaning apparatus for internally cleaning firearm suppressors is disclosed. The cleaning apparatus includes a reservoir configured to contain a cleaning fluid, a pump in fluid communication with the reservoir, and a spray tube coupled to the pump and dimensioned to be insertable within a firearm suppressor. The spray tube includes a sealed distal end and a plurality of apertures arranged to discharge pressurized fluid radially outward, with alternating patterns along opposing sides. A fluid return system collects the discharged fluid and recirculates it to the reservoir via a fluid return connector positioned above the reservoir floor to minimize particulate intake. The apparatus may include a cylindrical reservoir supported by a base housing, compression fittings, a removable lid, electrical controls, and an accessible drain assembly. A support structure holds the suppressor in a vertical orientation with drainage clearance. The system enables efficient, contained, and repeatable internal cleaning of firearm suppressors.

US12687367 - Projectile impact simulation device

A projectile impact simulation device comprising a housing, a mounting attachment, at least two high-voltage pins, and a shock zone. The housing has a circuit board electrically coupled to high-voltage receptacles that are configured to receive a first end of a high-voltage pin. The housing also has a back surface configured to rest adjacent to a user when the user wears the device. The mounting attachment is coupled to the back surface and configured to couple the device to the user. The high-voltage pins are embedded within the housing and configured to couple with the high-voltage receptacles. Two contact pads exposed on the back surface each have an electrical contact coupled with the high-voltage pins. When a voltage differential is applied across the contact pads, the device is configured to cause an electric arc in the shock zone. When the device is worn by a user, the electric arc shocks the user.

US12687368 - Device and systems for a semi-automatic crossbow

The disclosed technology includes a semi-automatic crossbow having a stock, a plurality of limbs, a drawstring, a bolt feeder, a barrel, a draw assembly, and a release. The draw assembly can be configured to automatically move the drawstring to a cocked position and the release can include a trigger and be configured to release the drawstring when the trigger is actuated. The disclosed technology can further include a truck configured to engage the drawstring and a bolt such that the bolt can be propelled forward by the truck when the drawstring is released by the release.
