摘要： A power tool may include a compartment in its housing and a first printed circuit board (PCB) located in the housing and electrically coupled to a first connector. An insertable wireless communication device may include a second electronic processor and an antenna that are each mounted to a second PCB. The insertable wireless communication device may be configured to be received in the compartment and may include a second connector configured to electrically and physically couple to the first connector. The insertable wireless communication device may be configured to wirelessly communicate with an external device. When the insertable wireless communication device is inserted into the compartment, a first conductive layer of the first PCB may be configured to be electrically coupled to the antenna via the first connector and the second connector such that the first conductive layer of the first PCB serves as a ground plane of the antenna.

摘要： An accessory for use with a rotary power tool having a rotatable spindle and a first mating member. The accessory includes a housing having a body and a plurality of arms extending therefrom, a hub selectively engagable with the spindle to lock the accessory to the power tool, and a sleeve slidable along the arms between a first position and a second position, where the sleeve includes a plurality of apertures through which the corresponding plurality of arms extend. When the sleeve is in the first position the sleeve locks the hub to the spindle to secure the accessory to the power tool, and wherein when the sleeve is in the second position the sleeve disengages the hub from the spindle to release the accessory from the power tool.

摘要： A fire hydrant tool for opening a fire hydrant in a controlled manner includes a cordless tool that has an output shaft and a trigger. A socket is attachable to the output shaft of the cordless tool and the socket has dimensions matching a top nut of a fire hydrant thereby facilitating the cordless tool to open the fire hydrant. A rod is attachable to the handle of the cordless tool thereby facilitating the rod to be gripped for manipulating the cordless tool. A ratchet driver is attached to the rod and the socket is attachable to the ratchet driver when the cordless tool has insufficient torque to loosen the top nut. A prying tool is coupled to the rod and the prying tool has a claw element and a hook element to grip an object for prying the object.

摘要： A pistol-grip type tool, such as an impact wrench, that is smaller than traditional impact wrenches, to allow for use in tight work areas. To minimize size and length, the tool includes a tool housing, a frameless motor, a rear motor bearing supported in a bearing pocket in the tool housing, and a nose housing coupled to the tool housing that supports and aligns a ring gear, bearing assembly, and impact mechanism with an axis of the motor.

摘要： The present invention relates to a method of commutation control of a brushless DC (BLDC) motor. The method uses a controller to control the BLDC motor using a modified six-step commutation. The method adds six intermediate steps that overlap the six-step commutation. Each of the six steps overlap with preceding and following steps, resulting in six additional intermediate steps in which all three phases are active. By doubling the number of steps, current and torque will vary less over time compared with current solutions without increasing the size or changing the design of the motor.

摘要： Overcurrent protection of an electrically powered, motorized device, such as a power tool, wherein the tool includes a tool housing, an output assembly, a trigger, an electrical safety device, a motor, an indicator, a controller, and a power source. The electrical safety device, for example a fuse, is disposed in series with a power connection from the power source to the controller. The controller measures current passing through the electrical safety device in time intervals when the trigger is actuated. The controller determines accumulated thermal energy passing through the electrical safety device, and compares the accumulated thermal energy to a threshold. If the accumulated thermal energy exceeds the threshold, the controller ceases or discontinues to allow power to be provided to the motor from the power source, thereby shutting off the motor. The controller may also activate the indicator to indicate a fault to the user.
