Abstract: A battery pack that includes a housing. The housing includes a support portion that is configured to removably connect to a device, such as a cordless, hand-held power tool. The battery pack is configured to electrically and/or communicatively connect to the device through at least one terminal. The at least one terminal can include a battery positive power terminal, a battery negative power terminal, and a communications terminal. In some embodiments, at least one of the terminals of the battery pack is positioned at a first depth level within the support portion and at least one of the terminals of the battery pack is positioned at a second depth level within the support portion. The battery pack includes a first distance between the first depth level and the second depth level (e.g., approximately 0.5 inches).

Abstract: A method includes determining a first voltage level of a first battery and a second voltage level of a second battery. Based on a difference between the first voltage level and the second voltage level satisfying a first threshold and a magnitude of a current failing to satisfy a second threshold, one of the first battery or the second battery is disconnected from the one or more components, and the one or more components of the portable device are powered using the other of the first battery or the second battery. Based on one or more of the difference between the first voltage level and the second voltage level failing to satisfy the first threshold or the magnitude of the current failing to satisfy the second threshold, the one or more components of the portable device are powered using the first battery and the second battery.

Abstract: A shroud of a vacuum cleaner that includes a housing supporting an impeller configured for creating a working airflow path between a dirty air inlet and an exhaust outlet. The shroud includes a forward wall having a shroud inlet, an annular axial wall, and an opening formed in the annular wall. The shroud inlet is configured to be aligned with an inlet of the impeller inlet along an axial direction, and the annular axial wall extends away from an outer perimeter of the forward wall along the axial direction. The opening is configured to be arranged in line with a portion of the exhaust outlet along the radial direction. The annular axial wall and the opening define an overall circumferential perimeter of the shroud. The annular axial wall occupies more than half of the overall circumferential perimeter, and the opening occupies less than half of the overall circumferential perimeter.

Abstract: A powered saw assembly includes a base having a top surface, a column fixed to the top surface, and a guide rail supported above the top surface. The assembly includes a saw unit translatable along the guide rail, the saw unit including a rotating arbor to which a saw blade is attachable for co-rotation therewith. A blade guard at least partially surrounds the saw blade and defines an opening through which the saw blade is movable for attaching or removing the saw blade relative to the arbor. A cover is movably coupled to the blade guard to selectively close the opening. With the cover moved away from the blade guard to expose the opening, the saw blade is attachable or removable relative to the arbor through the opening without passing the saw blade through the slot.
