Abstract: A power tool includes a housing, a battery coupled to the housing, and a battery cover which covers at least a portion of the battery. The battery cover includes an expandable portion. The expandable portion is moveable from a collapsed position to an expanded position. When the expandable portion is in the collapsed position, the battery cover has a first internal area. When the expandable portion is in the expanded position the battery cover has a second internal area. The first internal area is less than the second internal area.
Abstract: A table saw includes a frame; a saw having a cutting blade supported by the frame; first and second rails extending along opposite sides of the frame; a table supported by the frame; and a fence extending across the table between the first and second rail. A fence holder removably secures the fence to the first rail. The fence holder has a housing and an alignment arrangement configured to balance opposing forces between the fence holder housing and the first rail to hold the fence in a fixed angle relative to the first and second rails.
Abstract: A blower includes a main body which includes a housing and a fan disposed in the housing. The housing further defines an air discharge opening. The blower further includes an extension tube connected to the air discharge opening, the extension tube extending between a first end connected to the air discharge opening and a second end. The blower further includes a variable nozzle, the variable nozzle including a plurality of adjustable air control surfaces. The blower further includes a nozzle adjustment tube connected to the second end of the extension tube and at least partially surrounding the variable nozzle.

Abstract: A pouch-type battery comprising: a pouch-type battery case having a joined wall and a cell space within the pouch, a battery cell within the cell space, a terminal tab extending outwardly of the cell space from the battery cell, said joined wall comprising at least a first sealing portion having a first sealing strength, and a second sealing portion having a second sealing strength that is less than the first sealing strength such that the second sealing portion is adapted to fail before said first sealing portion, and an electrical contact located with the second sealing portion and adapted to change contact state upon failure of the second sealing portion.
Abstract: A battery pack including a housing having a longitudinal axis, a first surface, and a second surface, electrical terminals positioned within the housing and configured to engage and electrically couple with electrical terminals of a power tool, and a latch mechanism including an actuator that is movable within an aperture in the first surface and a latch member movable within an aperture in the second surface. The latch member includes a first latch portion having a first inclined surface and a second latch portion having a second inclined surface that intersects the first inclined surface. The actuator is depressible to retract the latch member within the housing.
Abstract: A device that includes a controller having a processing unit and a memory. The device includes an enable circuit. The enable circuit prevents the device from operating (e.g., discharging current and/or receiving charging current) until the enable circuit is activated. The enable circuit includes an activation component (e.g., a near-field communication [“NFC”] circuit). The activation component is configured or operable to cause the device to become enabled when the activation component is activated by an external enabling device.

Abstract: A fastener driver includes a drive blade movable from a retracted position to a driven position for driving a fastener into a work piece. The fastener driver further includes a gas spring mechanism for driving the drive blade from the retracted position to the driven position. The gas spring mechanism is moveable between a retracted state and a driven state. The fastener driver further includes a first return mechanism for moving the drive blade from the driven position toward the retracted position, and a second return mechanism for returning the gas spring mechanism toward the retracted state separately from movement of the drive blade.
Abstract: A digging apparatus (10, 300) is disclosed. The digging apparatus (10,300) includes a handle assembly (14, 14a, 314), a motor (32), a main switch (22, 322) electrically connected with the motor (32). The main switch (22,322) is movable between a first position in which operation of the motor (32) is allowed and a second position in which operation of the motor (32) is prevented, and a drilling bit (88, 88a, 388) is driven by the motor (32).

Abstract: A coupler includes a collar defining a member receiving passage. First and second lobes extend outwardly from the collar. The first lobe includes a lobe ramp surface, a cylindrical projection extending from the first lobe and radially surrounding the lobe ramp surface, and a gear extending from the cylindrical portion. A passage is defined in the first and second lobes and has a first axis. A lever arm is rotatable about the first axis. The lever arm includes a lever ramp surface. A pawl arm is movably connected to the lever arm. The pawl arm includes a portion biased into engagement with the gear teeth. A fastener extends through the passage and couples the lever arm to the first lobe so the lever ramp surface cams with the lobe ramp surface. Rotation of the lever arm in a first direction brings the first and second lobes toward each other.
