BATTERY PACK, POWER TOOL AND BATTERY PACK CHARGER SYSTEM
When providing alternating current (AC) power to operate AC powered devices such as power tools (such as drills, table saws, miter saws), equipment (such as lawn mowers), and consumer products (such as refrigerators, television, lights) without being tied to a fixed utility power supply typically requires a generator (such as an internal combustion engine based generator) or a battery powered inverter. In order to meet power and runtime needs for these devices, a battery powered inverter must be relatively large and expensive. This simple fact prohibits their use in many environments.
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 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.
A fastening tool includes a contact trip operatively associated with a contact trip switch to enable a fastener drive system to be fired when the contact trip reaches a firing position, after having engaged a work surface. If a dry-fire condition exists in a magazine connected to the fastening tool, the movement of the contact trip is completely taken up or absorbed by a biasing agent so that the contact trip switch is not closed. The biasing agent also limits the amount of force that can be applied to the contact trip switch in the event an operator slams the contact trip against a work surface or drops the fastening tool nose-first onto an unyielding surface.
A removable contact trip (460) can be received in an aperture of the barrel (414) and can be slidable between a retracted position and an extended position relative to an end of the barrel. The removable contact trip can define a muzzle aperture (500) aligned with the driver axis (134) and through which a fastener is driven by the nail driver (64). The removable contact trip can include a latch pocket (524). A removable contact trip latch (462) can be biased toward a latched position in which the removable contact trip latch extends through a window of the barrel (414) and is receivable in the latch pocket to latch the removable contact trip to the barrel. The removable contact trip latch can also be movable to an unlatched position in which the removable contact trip latch is not receivable in the latch pocket to unlatch and permit removal of the contact trip from the barrel.

A retaining portion is disposed between the mounting portion and the bearing portion and is adjacent to the mounting portion. An impact portion designed to receive the impact of a driver during a return stroke is disposed between the retaining portion and the bearing portion. The impact portion is bent at an oblique angle with respect to the drive axis.
A driver return assembly (18) can be positioned to return a concrete nail driver (64) of a cordless electric powered nailer (10) to the home position. A return rack (206) can be fixedly coupled to and positioned along a longitudinal length of the concrete nail driver. The driver return assembly can include a solenoid (230) driving a plunger (232) in a reciprocating motion in a homeward direction and a driven direction. A return pawl (204) can be coupled to the plunger and pivotable into a pawl raised position relative to the plunger in which the pawl is engageable with the return rack during movement of the plunger in the homeward direction, and pivotable into a pawl lowered position relative to the plunger in which the pawl is not engageable with the return rack during movement of the plunger in the driven direction.
A power take-off (PTO) assembly (38) of a cordless electric concrete nailer (10) includes a bracket (70) supporting a solenoid (60) and a compression spring (62a) and a linkage arm (58) coupled between a plunger (60a) of the solenoid and the compression spring. The linkage arm is biased by the compression spring toward the nail driver (50). A carrier (80) supports or carries a pinch roller (56) and the carrier is pivotably mounted to the bracket via a pivot pin. An engaging surface (58d) is movable with the plunger between an engagement position in which the engaging surface engages a cooperating engaging surface (80d) of the carrier and orients the carrier into a corresponding engagement orientation, and a disengagement position in which the engaging surface is spaced away from the cooperating engaging surface of the carrier, allowing the carrier to pivot outside the corresponding engagement orientation.

A direct fastening fastener particularly suited for use in normal weight or lightweight composite deck system. The fastener is heat treated to a dual-hardness level so that a portion of the fastener is capable of driving into the support member, such as a joist and a decking member. The remaining portion of the fastener remains relatively ductile so that it can withstand and transfer shear loads imposed by shifting of the concrete slab, which overlies the composite decking, to the support member. The fastener can be a single or multiple piece fastener which includes specially formed annular flanges that enhance interlocking between the fastener, the concrete slab and support members.
A concrete anchor capable of resisting large loads while requiring minimal embedment depth. The system includes a concrete structure including a cylindrical opening in the concrete surface thereof.

The plug includes an increasing diameter portion disposed toward a first end of the plug. The plug includes a locking opening. After installation, legs of the sleeve extend radially outward past the wall and the increasing diameter portion prevents inward movement of the legs to lock the sleeve and the plug in turn in the concrete cylindrical opening. Furthermore, dynamic loading on the plug via the locking opening when the anchor is in use generates a dynamic radially outward force on the legs to secure the anchor in the concrete hole.

In response to detecting a load greater than a threshold, the controller controls power output of the motor by setting conduction band of the motor switches and the advance angle to baseline values predetermined values. In response to detecting a load less than the threshold, the controller reduces at least one of the conduction band and the advance angle to a value less than the baseline values.
