An electronic switch module for a power tool is provided including a module body, a trigger moveable relative to the module body, a magnet being moveable relative to the module body with the trigger along a movement axis, and a linear Hall sensor fixed relative to the module body and intersecting the movement axis of the magnet. The linear Hall sensor magnetically detects a linear position of the magnet along the movement axis and outputs a voltage signal based on the detected linear position.

Switch module for a power tool

A wall panel system including a first wall panel, the first panel including at least a first panel hook portion. The system also including a second wall panel having a different configuration than the first wall panel. The second panel includes at least a second panel hook portion and a third panel hook portion opposing the second panel hook portion. The first wall panel is configured to engage with the second wall panel to create a wall panel assembly.

Wall hanging system

A lawn mower includes a frame, an operator support, a blade assembly, a steering system, a motor assembly, a sensor and one or more processors. The operator support is coupled to the frame and is configured to support the entire weight of an operator of the lawn mower during use thereof. The motor assembly is configured to drive rotatable wheels so as to move the frame along the ground surface and drive at least one blade relative to the ground surface to cut grass. Sensor and processor to detect the an edge between an unmowed area of grass and a mowed area of grass and control the motor assembly stop driving the at least one blade, the wheels, or both based on the input from the sensor.

Riding mower edge detection system

A battery pack and transport coupler for enabling the battery pack to reduce the pack power capacity. The battery pack include at least two strings of battery cells and a coupler provided at least partially inside the housing. The coupler is moveable between a first position, which causes the string of battery cells to be electrically connected inside the housing, and a second position, which causes the strings of battery cells to be electrically disconnected inside the housing.

Transport system for battery pack

A fuel transfer station may provide for the refilling of fuel canisters providing fuel to combustion powered equipment. The fuel transfer station may include a base, a frame coupled to the base, a first connection port and a second connection port provided in the base, and fluid flow lines connecting the first connection port and the second connection port. A supply tank may be supported by the frame and detachably connected to the first connection port. A fuel canister to be refilled may be detachably connected to the second connection port. Fuel contained in the supply tank may be selectively supplied to the fuel canister through the fluid flow lines in response to a pressure gradient drawing the fuel into the fuel canister.

Fuel transfer station and refillable fuel cell for fuel transfer station

A power tool is provided including a housing defining a cavity therein, where the housing includes a motor case and a handle portion extending along a longitudinal axis of the housing from the motor case; an electric motor having a drive shaft and mounted within the motor case; a partitioning wall extending radially and separating the motor case portion from the non-motor case portion of the housing; and a bearing pocket with an open end facing the motor case portion formed in the partitioning wall and a main body extending away from the electric motor for receiving a rotor bearing. The handle portion includes two elongate walls extending from the partitioning wall, a circuit board supported by the two elongate walls and including a motor drive circuit, and two covers secured to the two elongate walls to cover the circuit board.

Handheld power tool with brushless electric motor

A total task vehicle (TTV) may operate indoors to move a variety of different types of materials and accomplish a variety of different types of tasks, using tools and accessories powered by/connected to the TTV. One or more high power density (HD) battery packs may provide both 240V DC to 380V DC and 120V AC power to propel the TTV and also to function as a generator for tools and accessories attached to the TTV. A high torque/high speed convertible drive system may allow the TTV to operate in a ride-on mode, a walk-behind mode, providing for flexibility and adaptability in use of the TTV.

Total task vehicle

A jobsite computer network has a local server connectable to a remote server via the internet, a network access transceiver connected to the local server, and a wireless device in wireless communication with the network access transceiver. The network access transceiver receives a message from the wireless device and sends a message to the local server. The local server utilizes information from the message to determine the location of the wireless device. The network access transceiver and/or the wireless device generate data which is sent to the remote server.

Construction jobsite computer data network and location system

A motor assembly is provided including a stator and a rotor. The stator includes a stator main body defining a longitudinal axis, stator teeth projecting radially from the stator main body, stator windings wound around the stator teeth, and two winding terminals provided for each stator tooth extending away from the stator main body substantially parallel to the longitudinal axis. A circuit board is oriented along a radial plane adjacent the stator.
