Abstract: A system and method for capturing ice particles in a vacuum is provided. The system includes a clamshell apparatus. The clamshell includes a stand and a base positioned on top of the stand. A pair of linear actuators is operatively connected to the stand and a lid. The lid is operatively connected to the based movable between an open and closed position. The lid includes a grid with a plurality of apertures. An ultralight gel is positioned within the plurality of apertures and a soft metal sheet positioned behind the grid and the ultralight gel.

Abstract: An autonomous downhole robot tool string configured for navigating and collecting information in a downhole environment comprises a sensor head having a cylindrical housing positioned at a distal end of the tool string which includes a wobbler ultrasonic transducer with a tubular structure housing an ultrasonic transducer wherein the tubular structure is tiltable about the shaft, and wherein the distal end of the sensor head is mounted for panned movement about the longitudinal axis providing two degrees of freedom for the wobbler ultrasonic transducer. First and second caliper ultrasonic transducers are positioned on the cylindrical housing facing the downhole environment, each caliper transducers is configured to pan about an axis orthogonal to the longitudinal axis of the tool string. An electronics bay section coupled to the sensor head includes electronic circuits for controlling components of the sensor head.
