Power tool
It is an object of the present invention to provide a technique to increase efficiency of the output torque of the blushless motor to drive a power tool. A representative power tool may comprise a tool bit, a brushless motor to drive the tool bit, a battery to operate the brushless motor and a control device. The control device may operate the brushless motor by means of the battery. The control device may include an advance angle controlling section to control an advance angle of the brushless motor. According to the present teachings, the advance angle of the brushless motor may be determined based upon indexes that reflect working condition of the tool bit when the brushless motor is under the operation. By reflecting the working condition of the tool bit to the determination of the advance angle of the brushless motor, the brushless motor can be operated with higher efficiency under the various working condition such as a hard joint operation and a soft joint operation.

Hammer with integral lever mechanism
InactiveUS6279876B1Reduce the risk of injuryGood removal effectCrowbarsNail extractorsLong nailsNail removal
A hammer with integral lever mechanism is disclosed, comprised of a traditional handle and claw head. To increase leverage during nail removal and enable the user to remove longer nails with speed and ease, a lever is incorporated into the design of the device. The lever is T-shaped, and in its resting position is located inside of the head, so as to not interfere with use of the device when the lever is not needed. The lever can be rotated relative to the head by depressing a lever release button, to aid in nail removal . The lever is of ratchet style configuration, allowing the user to position the lever in a multitude of locations relative to the head, to assist in removing nails of various lengths. The lever is capable of being locked into position relative to the head at each of the lever's possible positions. A hand guard and finger grips permit the user to maintain a firm hold on the handle during use, thus reducing risk of injury. A retractable tape measure is incorporated into the design of the handle.

Pulsed rotation screw removal and insertion device
InactiveUS20050205274A1Reduce generationPrevent peelingDC motor speed/torque controlDerricks/mastsEngineeringInsertion device
A drill / driver (e.g. an electric drill) with a screwdriver bit attachment, and a method of controlling the drill / driver, are described. This method of control will greatly reduce the occurrence of stripped screw heads on most types of screws. By periodically stopping insertion of a screw and reversing direction of the screwdriver bit, the screwdriver bit will be reinserted fully back into the screw head. By ensuring the screwdriver bit is always fully inserted in the screw head, the stripping of a screw head will be prevented. This can be easily implemented on most types of powered screwdrivers including the most common device used for screw insertion on a construction job site, the cordless drill / driver.

ActiveUS20070074881A1Reduce impact speedReciprocating drilling machinesDerricks/mastsVibration controlControl signal
A pile driving control apparatus for a pile driving system includes a hydraulic control system that controls a throttle of a pile driving hammer, and thereby controls an impact velocity of the hammer with a pile. A controller provides a control signal to the hydraulic control system. Based on the control signal, the hydraulic control system controls an impact velocity of the hammer during a subsequent hammer stroke. The controller may determine one or more control parameters such as sound pressure at a sound control location during a hammer stroke, vibration at a vibration control location during a hammer stroke, an impact force imparted to the pile during a hammer stroke, and / or actual pile capacity of the pile, and provide to the hydraulic control system a control signal based on the determined control parameter(s).

Multi-purpose tool
A multipurpose tool is designed to meet the particular needs of commercial truck drivers. Preferably, it has a unitary, single-piece head which includes a chopping tool, a hammering tool, and a prying-pivoting tool, and a nail and / or staple removal assembly. Preferably, there are no sharp edges that are capable of cutting a person's skin. There are multiple surfaces and edges that may be easily wedged underneath an object to pry, lift, or force the object either in a proximal direction toward the user or in a distal direction away from the user, or upwards off a floor or truck bed. It may perform a multitude of functions, such as removing objects embedded in tires, tightening tire chains, repairing pallets (with a hammer / nail remover), moving pallets, prying open frozen doors, chopping ice (for example, removing ice build-up on vehicle). The head of the tool is slightly tilted to facilitate use as a lever. Other users, such as ranchers or farmers, will find the tool useful for repairing wire fences, stretching wire, pulling staples, and performing other small repairs.
