摘要:
Amperage control of a power tool motor is provided by pulse width modulation of current from a power supply. The pulse width modulation may be varied according to the determined motor current and measured power supply voltage. The power supply preferably includes a battery, such a lithium ion or nickel cadmium.

The present invention discloses a low foreign object damage nose weight for affixing to a either a standard or kinematic decoy flare comprising a thin walled nose cup having a closed end, an open end, an internal cavity, and at least one sidewall attached to said closed end and surrounding said internal cavity; and a metal powder disposed within the internal cavity for weighing down the forward end of the decoy flare, said nose cup capable of being affixed to a forward end of a decoy flare such that said powder is jettisoned from said nose cup upon burn out of a flare pellet subassembly of said decoy flare thereby reducing the weight of the nose cup and the possibility of foreign object damage to aircraft, ground troops, ground equipment and buildings resulting from the falling nose weight.

Provided herein are methods and systems relating to location-based services such as providing a geofencing, outputting location-based information on a mobile device, varying transmissions to and from a mobile device, and providing location-based alerts. More specifically, a method can include receiving a selected location on a mobile device, monitoring a current location of the mobile device, determining when the current location of the mobile device is within the geofence, and initiating an action on the mobile device associated with the geofence and the selected location.

A power tool control system includes a non-contact measurement and alignment device operative with the power tool and enabled to establish various readings, such as power tool settings. A graphical user interface communicatively coupled with the non-contact measurement and alignment device enables user control over and display of the readings from the non-contact measurement and alignment device. Related table saw assemblies are disclosed in which, for example, a bevel angle of a saw blade may be adjusted.

A router bit system includes a bit (or bits) and a bit holding assembly for attaching the bit to the drive shaft of a router without the use of additional hand tools. The bit holding assembly, which is attached to the drive shaft of the router, includes a chuck having a bore for receiving a shank of the bit. A collar for engaging and releasing the bit from the bit holding assembly slides between a first position for engaging the bit and a second position for releasing the bit. The collar is biased to the first position for engaging the bit. The bit is capable of being received in a standard collet-type bit holder, such as a standard router collet or the like.

A blade clamp assembly for retaining a rotary blade on the arbor of a rotary tool comprises a blade washer for engaging the blade to hold the blade on the arbor and a clamp assembly threaded into the arbor to clamp the blade washer against the blade. The clamp assembly includes a planetary gear system for transmitting torque applied to the clamp assembly to the blade washer, wherein the planetary gear system multiplies the torque transmitted to the blade washer so that the torque transmitted to the blade washer is greater than the torque applied to the clamp assembly.

A power tool may include a housing that supports an electrical circuit. The electrical circuit may include at least two terminal sets that are arranged in parallel to each other. The at least two terminal sets may include a first terminal set configured for engagement along a first axis to a battery pack having a first configuration and a second terminal set configured for engagement along a second axis to a battery pack having a second, different configuration. A battery charger may include a housing, and an interface that is electrically and mechanically compatible with at least two battery packs having different configurations and battery cell chemistries.
