Abstract: A medical robotic system includes a viewer for displaying an image of a work site, a gaze tracker for tracking a gaze point of a user on the viewer, and a processor. The processor is configured to: draw an area or volume defining shape, overlaid on the image of the work site, in a position determined by the gaze tracker; assign a fixed virtual constraint to the shape and constrain movement of a robotic tool according to the fixed virtual constraint; receive a user selected action command selecting an image of patient anatomy; and superimpose the selected image of the patient anatomy over the image of the work site within the shape. The selected image of the patient anatomy is registered to the image of the work site.

Abstract: A flowback tank cleaning system and method is described. A flowback tank includes a self-cleaning system. A flowback tank cleaning method may include moving solid debris collected at a bottom of a collection section of a flowback tank towards a lift auger using a cleaning auger or a conveyer belt extending along a length of the collection section, the bottom of the collection section including an angled trough, funneling solid debris towards the cleaning auger or conveyor belt by placing the cleaning auger or conveyor belt at a base of the angled trough, spraying fluid downward through a series of fluid outlets, removing the sand so moved by the cleaning auger or conveyer belt from the flowback tank using the lift auger, and removing the fluid from the flowback tank using a drain manifold below the cleaning auger or conveyer belt.
