    Abstract: One embodiment provides an electrical circuit coupled to an alternator. The electrical circuit includes a rotor and stator coils. The electrical circuit is configured to receive, at a point when an engine is operating, an electrical current that is induced in the stator coils by rotation of the rotor and charge a battery pack with the electrical current and inhibit generation of a spark by the engine while the alternator is powered by the battery pack until a speed of the alternator is greater than a threshold. The electrical circuit is further configured to power the alternator, at a point when the engine is not operating, with electrical current supplied by the battery pack coupled to a battery connector to start the engine.

    Abstract: System and method for a portable propane-fueled battery charger. One system includes a battery charger including a propane fuel line and an engine including an output shaft. The engine is configured to receive propane via the propane fuel line and rotationally drive the output shaft. The battery charger further includes an alternator including a rotor and stator coils. The output shaft is mechanically coupled to the rotor, and the rotor is rotationally driven by the output shaft. An electrical current is induced in the stator coils by rotation of the rotor. The battery charger further includes an electrical circuit that receives the electrical current and is configured to determine when a battery pack is coupled to a battery connector, and charge the battery pack.

    Abstract: A pipeline inspection device including a cable having a camera disposed on a distal end of the cable, where the camera and the cable are configured to be directed into a conduit. A first drum includes a rear wall, a front wall, and a side wall defining an interior, where the front wall has an opening providing access to the interior, and where the cable is disposed at least partially within the first drum. A stand supports the first drum, where the first drum is rotatably coupled to the stand. A hub houses electrical components of the pipeline inspection device. The hub is removably received in the interior of the first drum via the opening, where the hub is selectively removable from the first drum and insertable into an interior of a second drum.
