  • Publication number: 20060119318
    Abstract: A battery pack for powering a cordless power tool. The battery pack includes at least one battery cell operable to supply a discharge current, a switch operable to control the discharge current and a protection device to protect the switch. The protection device is positioned such that the device absorbs a current traveling in a direction opposite to that of the discharge current supplied from the battery cell.

  • Publication number: 20050050505
    Abstract: An integrated circuit chip (104) having a contact layer (136) that includes a plurality of Vdd, Vddx, ground and I/O contacts (116, 120, 124, 128) arranged in a generally radial pattern having diagonal and major axis symmetry and generally defining four quadrants. An X-Y power grid (140) is located beneath the contact layer and includes metal layers (LM?) each having a plurality of wires (68) extending in one direction. The direction of the wires alternates from one metal layer to the next adjacent metal layer. A wiring layer (IM) is interposed between the contact layer and power grid layers to provide a well-behaved electrical transition between the generally radial Vdd, Vddx and ground contacts and the rectangular X-Y power grid. The interposed wiring layer includes concentric square rings of Vdd, Vddx and ground wires (144, 148, 152) located alternatingly with one another.

  • Publication number: 20050039153
    Abstract: Macro design techniques are disclosed for facilitating subsequent stage wiring across the macro. Whitespace areas within the macro are rearranged to accommodate the wiring. The rearrangement may take the form of physical rearrangement of the whitespace areas into routing tracks extending from one side of the macro to another; shielding using, for example, macro power bussing and/or macro wiring; routing power busses to the rearranged whitespace; and/or inserting active circuits with pins accessible to the wiring. In a preferred embodiment, active circuits are placed into rearranged macro whitespace during the design of subsequent stages. The rearrangement of the whitespace facilitates the wiring across the macro so that slew rate and path delay requirements of the subsequent stage wiring can be maintained, without excessive buffering or rerouting of wiring.

  • Publication number: 20050016001
    Abstract: A drive mechanism for a power tool, a power tool and a reciprocating saw. The power tool includes a housing, a motor supported by the housing and including a drive shaft, an output member supported by the housing and adapted to support a tool element, and a drive mechanism. The drive mechanism includes a drive assembly driven by the drive shaft for rotation about an axis, the drive assembly including a gear, a hub selectively driven by the gear for rotation about the axis, and structure positioned between the gear and the hub, the structure selectively transmitting drive force between the gear and the hub and selectively allows relative movement between the gear and the hub. The drive mechanism may also include a drive arm drivingly connected between the drive assembly and the output member of a tool, and the drive arm may be configured to absorb an impact.

  • Publication number: 20050000097
    Abstract: Abstract of the Disclosure A power tool, such as a reciprocating saw. The power tool generally includes a spindle for supporting a tool element, a body defining a pivot axis and housing a motor and a drive mechanism driven by the motor, the drive mechanism driving the spindle, the body having a forward end supporting the spindle and a rearward end, and a grip connected to the rearward end of the body for pivoting movement about the pivot axis. The power tool may include a locking assembly for locking the grip in a pivoted position relative to the body and a switch assembly at least partially supported on the grip. The switch assembly is preferably inoperable when the locking assembly is in an unlocked condition, and the locking assembly preferably cannot be moved to the unlocked condition when the switch assembly is in an operating condition.
