Abstract: An ultrasonic instrument includes a body, an actuation assembly, a shaft assembly, and an end effector. The actuation assembly includes an activation member that is operable to move in a first direction to select a mode of operation. The shaft assembly extends distally from the body and includes an acoustic waveguide. The end effector includes an ultrasonic blade that is in acoustic communication with the acoustic waveguide. The activation member is operable to move in a second direction to activate the end effector in a mode of operation selected by movement of the activation member in the first direction.

Abstract: The presently disclosed technology is directed to a golf club head. For example, the golf club head includes a striking face portion, an upper back portion, and a removable weight assembly. The sole may include a sole recess and a sole blind hole. The removable weight assembly may include a cylindrical weight to fit into the sole blind hole and a weight cover to cover the cylindrical weight in an installed position.

Abstract: A golf club head includes a recessed channel; and a weight assembly including a weight at least partially disposed within the recessed channel, a cover at least partially covering the recessed channel, the cover including a cover main body, a top rail protruding from the cover main body along a first direction, and a side rail protruding from the cover main body along a second direction different from the first direction, and a fastener coupling the cover to the body, wherein the weight has top and side grooves that are respectively shaped and sized to receive at least part of the top and side rails, wherein the top groove has opposite front and rear surfaces respectively proximal and distal to the striking face, and wherein the side groove has opposite top and bottom surfaces respectively proximal and distal to an exterior surface of the cover.

Abstract: A golf club head, including: a body including: a striking face having a lower leading edge, and a sole extending from the lower leading edge, wherein the striking face and the sole form part of an outer surface of the body; a recessed channel formed in the outer surface of the body; and a weight assembly including: a weight at least partially disposed within the recessed channel and configured to be moveable therein, a cover adapted to releasably secure the weight within the recessed channel, and having one or more window openings adapted to identify a location of the weight within recessed channel; and an at least partially transparent window member attached to the cover and overlapping the one or more window openings.
