A piledriving apparatus for driving stakes or posts into the ground includes a housing and a ram mounted in the housing. A head is attached to the ram and defines a cavity for receiving a stake. The ram is operable to drive the head against the stake to urge the stake into the ground. Grips for holding the apparatus by the hands of a user are described and claimed. Controls for directing the direction, force, and speed of a piston rod of the ram is disclosed and claimed.

The present disclosure relates to compact waveguide impact devices. One example includes a branching compact mechanical waveguide that has at least one input impact location and at least one input impact location output impact point. The compact waveguide impact device also includes at least one input impact component. A controller device activates the at least one input impact component to strike the at least one input impact location according to an input impact pattern, thereby producing a desired output impact pattern.
