Abstract: A multi-dimensional image rendering device for displaying multi-dimensional images by layering 2D physical pixel configurations featuring a plurality of tubes in a tank, the inner cavities of the tubes are each filled with a liquid medium such that an air pocket is disposed at the first end of each tube; displacement components slidably disposed in the inner cavity of each tube that can slide between a down position and an up position; a tube aperture disposed in each tube; and a moving means operatively connected to each displacement component functioning to systematically move the respective displacement component a fixed distance creating uniform air bubbles.

Abstract: A power tool includes an output shaft configured to rotate about a longitudinal axis, a motor drivably connected to the output shaft to impart rotary motions thereto, and a rotational motion sensor spatially separated from the output shaft and operable to determine the user-imparted rotational motion of the power tool with respect to the longitudinal axis. A controller is electrically connected to the rotational motion sensor and the motor. The controller determines angular velocity of the power tool about the axis, rotational displacement of the power tool about the axis, and/or a direction of the rotational displacement using input from the rotational motion sensor. The controller then controls the motor according to the angular velocity, the rotational displacement, and/or the direction of the rotational displacement.

Abstract: A control system is provided for use in a power tool. The control system includes: a rotational rate sensor having a resonating mass and a controller electrically connected to the rotational rate sensor. The rotational rate sensor detects lateral displacement of the resonating mass and generates a signal indicative of the detected lateral displacement, such that the lateral displacement is directly proportional to a rotational speed at which the power tool rotates about an axis of the rotary shaft. Based on the generated signal, the controller initiates a protective operation to avoid further undesirable rotation of the power tool. The controller may opt to reduce the torque applied to shaft to a non-zero value that enables the operator to regain control of the tool.

Abstract: An anvil adapted to be received within an impact wrench comprises a round body and a square head. The square head is formed at an end of the round body. A tapered ramp extends from the round body to the square head. A radius is formed in the tapered ramp.

Abstract: A handle for a power tool is provided including a field case and front handle portion formed as a single piece. The front handle portion has an opening in a rear side thereof for receiving the wiring for the power tool. The wiring is connected to a motor that is mounted in the field case. A rear handle portion is attached to the front handle portion for covering the opening in the rear of the front handle portion. An end cap is connected to a rear of the field case for covering the remaining exposed wires connected to the motor. With the front handle design, the wire-up of the power tool can be completed from one side of the tool without having to turn the tool over during the wire-up process.

Abstract: A system of cordless power tools includes a cordless power tool adapted to removably receive a rechargeable battery pack. The battery pack and the power tool can have complementary grooves and rails or L-shaped surfaces that aid in aligning the positive and negative blade terminals of the battery pack to the positive and negative tool terminals, respectively, of the power tool.

Abstract: A variable speed drill includes a housing and a motor within the housing. The motor has (a) a motor field lamination diameter greater than 65 mm, (b) a motor current rating greater than 8 amps, (c) a motor power level greater than 600 Watts, (d) a maximum torque level at the chuck greater than 580 in-lbs, (e) a weight greater than 5.5 pounds or (f) a maximum speed less than 550 rpm. A mixing implement is rotationally coupled to the motor. A variable speed switch is mounted to the housing and is operable to vary a rotational speed of the motor and therefore of the mixing implement.
