Abstract: A wearable air filtration apparatus configured to fit beneath a full-face helmet is disclosed. The apparatus includes a front plate including an output aperture and at least one input aperture, the input and output apertures arranged to be substantially front facing when the apparatus is worn by a user. An air filter is arranged behind the front plate and positioned to filter air moving from in front of the apparatus toward the face of a user wearing the apparatus. A valve plate is located behind the filter, the valve plate including an output check valve in fluid communication with the output aperture and at least one input check valve in fluid communication with the at least one input aperture.

Abstract: Example systems, devices, and methods related to an automated target system are provided. In this regard, a target pod device, that may be installed in a target base is provided. The target pod device may include a hinge, a target paddle, a rotary actuator, a sensor, and a processor. The target paddle may be operably coupled to the hinge and the rotary actuator may be operably coupled to the target paddle. The rotary actuator may be configured to rotate the target paddle to a deployed position or a retracted position. The sensor may detect that the target paddle has been moved toward the retracted position. The processor may be configured to transmit a signal to the rotary actuator to cause the rotary actuator to rotate the target paddle, and determine whether the target paddle has been moved toward the retracted position by a projectile.
