Abstract: In one embodiment, a reciprocating tool includes a reciprocating plunger, the plunger including an inner wall defining a chamber portion within the plunger, a motor operably connected to the plunger, and a bushing located at least partially within the chamber and contacting the inner wall.

Abstract: An automation testing apparatus includes a controller that is configured to receive a set of one or more commands that are part of a test and programmatically manipulate a set of components that connect the automation testing apparatus with a device under test (DUT) to test the DUT according to the set of commands The set of components may include a power switch that is configured to turn on and off power to the DUT, a communication controller that is configured to send commands to be executed by the DUT, and an audio/video switch that is configured to turn on and off audio and/or video of the DUT. The controller logs the set of commands executed and a result of execution of the set of commands to analyze whether the test passed.

Abstract: In one embodiment, a reciprocating tool includes an elongated spindle configured to reciprocate along its lengthwise axis, a wobble drive mechanism operably connected to the elongated spindle, an elongated rocker assembly having an upper end portion operably connected to the spindle, a lower end portion, and a pivot located between the upper and lower end portions, and a counterweight operably connected to the lower end portion, such that as the elongated spindle reciprocates along its lengthwise axis, the counterweight is driven by the elongated rocker assembly to reciprocate along the axis.

Abstract: In one embodiment, a reciprocating tool includes a reciprocating plunger, the plunger including an inner wall defining a chamber portion within the plunger, a motor operably connected to the plunger, and a bushing located at least partially within the chamber and contacting the inner wall.

Abstract: A drive apparatus for a reciprocating tool, including a housing, a rotatable drive shaft assembly located in the housing, an elongated spindle located in the housing for reciprocating motion, a front bushing in the housing for supporting the front end portion of the spindle, and a wobble drive mechanism. The wobble drive mechanism preferably includes a wobble drive shaft connected to the drive shaft assembly and an elongated arm having a lengthwise axis extending upwardly from the wobble drive shaft and including an upper interface for reciprocating the spindle generally in its lengthwise direction during alternating cutting and return strokes. The upper interface connects the arm to the spindle in a manner that prevents translational movement of the spindle relative to the arm in the direction of the arm lengthwise axis, but permits rotational movement thereof in three orthogonal axes.
