A power tool is provided including a power supply interface receiving a removable battery pack, a brushless direct current (BLDC) motor including a rotor and a stator, and a multi-phase inverter bridge circuit. A controller is provided to output drive signals to the inverter bridge circuit to control flow of current from to the motor, where each drive signal is activated within each corresponding phase of the motor within a conduction band. The controller is configured to control a length of the conduction band at a variable value within a first torque range below a torque threshold and at a substantially constant value within a second torque range above the torque threshold. The torque threshold is greater than approximately 1 Newton-meters and the motor produces a maximum power output of at least approximately 1250 watts at the torque of approximately 1 Newton-meters.

High-power battery-operated power tool

A power tool is provided comprising: a motor, an output shaft driven by the motor along a longitudinal axis, a fan rotationally coupled to the motor to generate an airflow, and a housing comprising two calm shells mated together to support the motor and forming a back wall behind the motor along the longitudinal axis. The rear wall includes a plurality of air intakes. An end cap is attached to the housing adjacent the rear wall with an air gap therebetween. The airflow generated by the fan enters through the air gap in a substantially radial direction, then passes through the plurality of air intakes to enter the housing in thermal contact with the motor.

Power tool

A method of manufacturing a battery pack including the creation of a support board for enabling conversion of the battery pack from providing a first voltage to providing a second voltage. The support board is created by injection molding about a precut set of power traces for coupling a converting element to a plurality of battery cells. The power traces couple the plurality of battery cells to a set of battery pack terminals. The support board may be mechanically coupled to a battery cell holder.

Battery pack and method of manufacture

An impact tool includes a controller configured to control power being delivered to the and operable in one of: (a) a normal mode where the controller allows power to be delivered to the motor so that the impact mechanism transitions from operation in the rotary mode to operation in the impacting mode when an output torque exceeds a normal transition torque; and (b) a control mode where the controller controls power being delivered to the motor so that the impact mechanism transitions from operation in the rotary mode to operation in the impacting mode when an output torque exceeds a control transition torque that is greater than the normal transition torque.

Impact tool with control mode

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 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. The circuit board includes a central through-hole through which a rotor shaft extends, at least one magnetic sensor mounted on a surface of the circuit board around the central through-hole configured to magnetically interface with the rotor, peripheral openings arranged to receive the winding terminals of the stator, and conductive routings extending from the peripheral openings to connect the stator windings in a series or a parallel configuration and/or a wye or a delta configuration.

Circuit board for connecting motor windings

An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electromechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state.

Electro-mechanical lock core

A system for remotely retrieving sensed conditions at one or more building components. The building components are remote or numerous so that a wireless collection of the sensed conditions provides a significant benefit to a builder or building operator. A remote transceiver sends a wireless signal to a building component. The building component includes an onboard transceiver. At least some of the energy from the transmitted wireless signal is received by the onboard transceiver, sent to a storage device, and stored therein. The stored energy is used to operate a sensor for sensing an onboard condition. The onboard condition is then wirelessly transmitted by the onboard transceiver back to the remote transceiver to be displayed.
