    Abstract: A vacuum cleaner includes a vacuum body assembly. The vacuum body assembly includes a housing having a base end, a mount hook connected to the housing, a debris container removably coupled to the housing, and a suction source. The suction source is able to draw air into the debris container. A harness assembly is removably connected to the vacuum body assembly. The vacuum cleaner is convertible between a carry mode, a stand mode, and a hang mode. The harness assembly is connected to the vacuum body assembly in the carry mode, and the harness assembly is to be worn by a user. The base end of the vacuum body assembly may rest on a support surface in the stand mode. The hook of the vacuum body assembly may hang the body assembly from a mount structure in the hang mode.

    Abstract: A wireless transmission system logs and communicates a location of an object. The wireless transmission system includes a wireless antenna configured to transmit a first beacon signal and a second advertising beacon signal. The system also includes a processor and a memory that stores instructions executable by the processor. The instructions cause the wireless antenna to repeatedly transmit the first beacon signal through a first number of transmission repetitions spaced at a first repeat interval. After completing the first number of transmission repetitions, the wireless antenna withholds transmission during a transition interval. After the transition interval, the wireless antenna repeatedly transmits the second advertising beacon signal through a second number of transmission repetitions at a second repeat interval. The wireless antenna, memory, and processor may be integrated in to a mountable housing and attached to an object or integrated with the tool.

    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.
