Abstract: Embodiments of the present invention provide methods and systems of temporally smoothing the distortion of a light beam caused by imperfections of an optical element or optical system through which the light beam passes. The optical element is moved relative to the light beam to change a position of the imperfections in the path of the light beam to distribute the distortion of the light beam caused by the imperfection without substantially changing the path of the light beam. In some embodiments, the optical element is axially symmetric with respect to its optical axis, and the distortion of the light beam is distributed by rotating the optical element around its optical axis. In some embodiments, the optical element has geometric uniformity relative to a plane or along a line in a plane, and the distortion of the light beam is distributed by moving the optical element along the plane, or along the line of symmetry in the plane.

Abstract: The tool includes an elongated handle having a first end and second end, wherein a handle grip is rotatably coupled with the first end, and a working end is coupled with the second end. The working end may include a plurality of spaced tines with the prongs having points, wherein at least one cutting blade is coupled to the device between adjacent tines allowing a user to slide the tines of the fork along the ground surface, thereby using the blade to harvest vegetation. Additionally, the working end allows a stack of cut vegetation to accumulate on the device to be carried and placed in a preferred location or container.

Abstract: A surgical instrument for enhancing robotic surgery generally includes an elongate shaft with an ultrasound probe, an end effector at the distal end of the shaft, and a base at the proximal end of the shaft. The end effector includes an ultrasound probe tip and the surgical instrument is generally configured for convenient positioning of the probe tip within a surgical site by a robotic surgical system. Ultrasound energy delivered by the probe tip may be used to cut, cauterize, or achieve various other desired effects on tissue at a surgical site. In various embodiments, the end effector also includes a gripper, for gripping tissue in cooperation with the ultrasound probe tip. The base is generally configured to removably couple the surgical instrument to a robotic surgical system and to transmit forces from the surgical system to the end effector, through the elongate shaft.

Abstract: A rounded cornerbead sanding tool including a female pole adapter for attachment to common extension poles. Two (2) separated pivot joints allowing greater angle accessibility including inverted angles. Three (3) interchangeable sanding sponge forming arms to form sanding sponge to recessed or protruding "U" shape for sanding "Outside" or "Inside" cornerbeads, angles and flat surfaces. Slot formed through center of larger than now commonly available sanding sponge for attachment to tool head.
