Abstract: A crankcase ventilation system is disclosed that includes a PCV valve, a spigot and a tube connector. The PCV valve is enclosed in a module housing that encloses a plunger, and a spring. The module housing defines an inlet opening, and an outlet opening and is assembled inside an engine component. The spigot is attached to an outer surface of the engine and is in fluid communication with the PCV valve through the outlet opening. The tube connector is in fluid communication with the tube connector and the PCV valve. An intake manifold of the engine provides vacuum to the PCV valve, through the tube, the tube connector and the spigot. If one of the tube, tube connector, or spigot is detached from the engine, the PCV valve is retained in the engine and is held closed by the spring biasing the plunger against the inlet opening.

Abstract: A firearm environmental recording apparatus, which may be used with a firearm environmental recording system, may include: a firearm attachment structure configured to attach to portions of a firearm; a processing unit; a camera configured to record image data; a microphone configured to record audio data; and an inertial sensor module configured to provide to orientation data. The image data, audio data, and orientation data may be associated with and/or stored in a database, such as a database of a network. Preferably, the apparatus may comprise a key which may be removably coupled to the body of the apparatus, and the key may govern or enable a first processor of the apparatus to access data in an auxiliary data store of the apparatus.
