Abstract: A pneumatic fastener driver is operable in a single sequential mode and a bump-fire mode. The pneumatic fastener driver includes a housing, a nosepiece extending from the housing from which fasteners are ejected, and a trigger moveable between a default position, in which a drive cycle is inhibited from initiating, and a depressed position, in which the drive cycle is permitted to be initiated. The pneumatic fastener driver further includes a contact arm movable relative to the nosepiece between an extended position and a retracted position, and a timeout mechanism operable in the bump-fire mode to inhibit the drive cycle from being initiated in response to inactivity of the contact arm over a preset time interval that begins once the trigger is actuated from the default position to the depressed position.

Abstract: A ceiling fan may include a housing having a central longitudinal axis, an inlet, and an interior in fluid communication with the inlet. The ceiling fan may include a nozzle disposed around a portion of the housing that may be spaced a distance apart from the housing and define an interior passageway and an outlet in fluid communication with the interior passageway. The ceiling fan may include a conduit disposed between portions of the housing and the nozzle in fluid communication with the interior of the housing and the interior passageway of the nozzle. The fan may further include an impeller disposed in the housing and a motor coupled to the impeller. The motor may rotate the impeller for drawing air into the interior of the housing through the inlet, moving air through the conduit and the interior passageway, and expelling air out of the outlet in a preferential direction.

Abstract: A light and fan assembly may include a body having a first side configured to be positioned adjacent to a ceiling, a second side opposite the first side, and an internal cavity disposed between the first side and the second side. The light and fan assembly may also include a light unit disposed on the second side of the body. The light unit may have an outer perimeter. At least a portion of the outer perimeter may be spaced apart from the body to define an outlet therebetween. The light and fan assembly may further include a motor positioned within the internal cavity, and a fan positioned within the internal cavity and coupled to the motor. The fan may be operable to draw air into the internal cavity and exhaust the air out of the body through the outlet.

Abstract: A fan may include a housing with an air inlet and an air outlet, a motor disposed in the housing, and an impeller disposed in the housing and coupled to the motor. The impeller may be operable to be rotated by the motor for drawing air into the air inlet and expelling the air from the air outlet. The fan may also include a diffuser disposed at least partially in the housing. The diffuser may have a bowl-shape and the bowl-shape may define an air diffusing surface over which the air moves towards the air outlet.

Abstract: A fan includes a central hub defining an inlet, a motor positioned within the central hub, and an impeller positioned within the central hub. The impeller is operable to be rotated by the motor to generate air movement. The fan also includes a nozzle defining a channel that receives the airflow from the central hub. The nozzle also defines an outlet in communication with the channel to direct air out of the nozzle. The fan further includes a plurality of conduits connecting the nozzle to the central hub to direct air from the central hub to the channel and through the outlet of the nozzle. The nozzle defines a projection aligned with each conduit to divide air movement through the nozzle.

Abstract: A rechargeable battery pack including a housing including a bottom wall and a top wall opposite the bottom wall, a plurality of battery cells at least partially positioned within the housing, and a latch mechanism. Where the latch mechanism includes a first linkage member having a contact surface accessible by the user from outside the housing, and where the contact surface is positioned proximate the bottom wall of the housing, a locking pawl movable with respect to the housing between a locked position and an unlocked position and in operable communication with the first linkage member, and where the locking pawl is positioned proximate the top wall of the housing.

Abstract: A modular garage door opener system and method including a garage door opener having a motor that is configured to be coupled to a garage door to open and close the garage door. The garage door opener includes a first accessory port including a first accessory mounting interface and a second accessory port disposed on the garage door opener including a second accessory mounting interface. An accessory device including a first mounting interface engages the first accessory mounting interface to couple the accessory device to the first accessory port. The accessory device may be disengaged from the first accessory mounting interface and then engage the second accessory mounting interface to couple the accessory device to the second accessory port. Additionally, a second accessory device may engage the first accessory port after disengagement of the accessory device.

Abstract: A rechargeable battery pack including a housing, a plurality of battery cells at least partially positioned within the housing, and a latch mechanism. The latch mechanism including a first linkage member, a second linkage member in operable communication with the first linkage member, and a locking pawl directly coupled to the second linkage member and movable with respect to the housing between a locked position and an unlocked position.

Abstract: A window covering assembly includes a roller to which a window cover is attached and a motorized assembly. The motorized assembly imparts a force via a power transmission system to the roller, thereby causing the roller to rotate and the window covering to raise or lower. The roller and motorized assembly are modular and are not permanently joined to each other.

Abstract: A cutting tool is configured to cut a tube. The cutting tool comprises a tube cutter. The tube cutter includes a housing having a blade opening and a profile defining a tube opening configured to receive the tube.
