Abstract: 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.

Abstract: An example power tool includes a battery pack receiving portion including a battery pack compartment including a battery pack support structure configured to receive and support a battery pack including battery terminals. The power tool further includes a terminal block located in the battery pack receiving portion and including tool terminals. At least two terminals of the tool terminals are configured to electrically and physically couple to the battery terminals. The power tool further includes an insertable device compartment located in the battery pack receiving portion and configured to receive an insertable wireless communication device including a first electronic processor, a transceiver, and device terminals. At least one device terminal is configured to electrically and physically couple to at least one shared terminal of the at least two terminals of the tool terminals. The insertable wireless communication device is configured to wirelessly communicate with an external device.

Abstract: 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 ball detent selectively engagable with the spindle to lock the accessory to the power tool, a sleeve slidable along the arms between a first position in which the sleeve biases the ball detent into engagement with the spindle to axially secure the accessory to the tool, and a second position in which the ball detent is disengageable from the spindle to release the accessory from the tool, and a second mating member coupled to the arms of the housing.

Abstract: A disclosed electrical generator includes a housing, an actuator, a rotatable member, a stator, a rotor, an electrical circuit, and a current controller. The actuator is movable relative to the housing and the rotatable member is also rotatable relative to the housing. The rotatable member cooperates with the actuator such that movement of the actuator causes rotation of the rotatable member. The stator is fixed relative to the housing and the rotor receives rotational kinetic energy from the rotatable member. Movement of the rotor relative to the stator generates electromagnetic induction in the rotor and/or the stator which produces a three-phase alternating current. The electrical circuit includes a rectifier that converts the alternating current to a direct current. The current controller regulates the direct current to thereby generate a fixed constant direct current.

Abstract: An electrical generator configured to convert kinetic energy into electrical energy. The electrical generator comprises: a housing; an actuator movable relative to the housing; and a rotatable member being rotatable relative to the housing and configured to cooperate with the actuator such that movement of the actuator causes rotation of the rotatable member. The electrical generator further comprises: a stator fixedly attached to the housing; and a rotor configured to receive rotational kinetic energy from the rotatable member. The rotor and stator are configured to interact such that rotation of the rotor relative to the stator results in electromagnetic induction in the rotor and/or the stator which produces three- phase alternating current. The electrical generator further comprises: an electronic circuit comprising a rectifier configured to convert the alternating current to direct current; and a current controller configured to regulate the direct current to be a fixed constant current.

Abstract: A fluid flow control valve comprises a housing defining a fluid flow passage extending longitudinally therethrough, the housing having opposite ends each defining an opening for flow into and out of the fluid flow passage, and an orifice and diaphragm disposed in the housing. The orifice has a seat at one end thereof facing the diaphragm. The diaphragm has one end face that opposes the seat of the orifice, the seat being configured such that one or more flow control passages are defined between the seat and the one end face of the diaphragm through which the fluid flows. The seat is contoured to include at least two different shapes of channels each promoting localized bending of the diaphragm at a different pressure differential, thereby permitting an expansion of the working pressure range to very low pressure differentials.
