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 knife including a body with a first end, a second end opposite the first end, and a longitudinal axis that extends centrally through the first end and the second end. The knife further includes a first scoring tip that points in a first direction, a second scoring tip that points in a second direction opposite the first direction, and a scoring tip axis that extends centrally through the first scoring tip and the second scoring tip. The scoring tip axis is perpendicular to the longitudinal axis. A chisel extends from the second end of the body and the longitudinal axis of the body extends centrally through the chisel.

Abstract: A battery pack containing a frame; and two or more battery cells installed to the frame. The two or more battery cells are interconnected by a configurable connector which is configured to enable electrical connections between the two or more battery cells. The configurable connector is adapted to be configured in a first status or a second status. In the first status, the two or more battery cells are electrically connected, and in the second status, the two or more battery cells are not electrically connected. The battery pack is not fully operational without the terminal holder inserted, therefore before it is delivered to the end user the energy loss due to self-discharging during storage and shipping can be minimized.

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 hedge trimmer comprises: a drive motor (30, 130) disposed in a casing (21, 121); a gear mechanism disposed in the casing (21, 121) and connected to the drive motor (30, 130); and a blade arrangement having at least one cutter bar (20, 120). The at least one cutter bar (20, 120) is driven in a reciprocating manner in a longitudinal direction of the blade arrangement by the drive motor (30, 130) via the gear mechanism. The gear mechanism contains at least a first gear setting and a second gear setting producing two different gear-ratios, such that the at least one cutter bar (20, 120) is adapted to be driven at a first speed and torque using the first gear setting, and a second speed and torque different from the first speed and torque using the second gear setting.

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 cleaning head housing for a floor cleaner that moves along a surface to be cleaned includes a brushroll chamber defining a top surface having a top opening and a bottom surface having a bottom opening positioned closer to the surface to be cleaned than the top opening. A suction nozzle has an upper nozzle wall, a lower nozzle wall, and a nozzle passageway formed between the upper and lower nozzle walls. The suction nozzle is releaseably connected to the brushroll chamber to selectively cover the top opening of the brushroll chamber. A brushroll is positioned within the brushroll chamber and engages the surface to be cleaned through the bottom opening of the brushroll chamber. The brushroll is accessible through the top opening for cleaning while the suction nozzle is disconnected from the brushroll chamber. The brushroll is removable from the brushroll chamber other than through the top opening.

Abstract: A cleaning system comprising a vacuum source, a current sensor, a recovery tank having a shutoff float configured to float on a surface of fluid within the recovery tank, and a controller. The vacuum source is in fluid communication with a suction inlet via first and second air paths within the recovery tank. The shutoff float is further configured to block the first air path upon the fluid within the recovery tank reaching a desired level. The controller is configured to receive, from the current sensor, a signal indicative of the current drawn by the vacuum source. The controller is further configured to determine, based on the current drawn by the vacuum source crossing a threshold, the fluid within the recovery tank has reached the desired level and control an operating element of the cleaning system upon determining the fluid within the recovery tank has reached the desired level.

Abstract: A floor cleaner having a recovery tank, a suction source, and a filter basket. The suction source is configured to generate an airflow along a fluid flow path to draw fluid and debris from a surface to be cleaned into the recovery tank. The recovery tank has an outlet duct on a tank body. The filter basket is positioned in the outlet duct on the tank body and configured to filter debris from the airflow.

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.
