Abstract: According to some aspects, a system for identifying a printed object is provided. The system may include an imaging device configured to image a three-dimensional (3D) printed object and a processor coupled to the imaging device. The processor may be configured to receive information generated as a result of imaging the 3D printed object with the imaging device, identify a set of features for the 3D printed object using the received information, compare the set of features with multiple reference sets of features, each of the multiple reference sets of features being associated with a respective 3D object in a plurality of 3D objects, and identify, based at least in part on results of the comparison, a 3D object from the plurality of 3D objects that matches the 3D printed object.

Abstract: Membrane distillation system. The system includes a solar radiation absorbing porous membrane positioned to receive solar radiation to heat the membrane. A transparent cover is spaced apart from the membrane to form a channel through which a saline feed stream flows. A condensation structure is spaced apart from an opposite side of the porous membrane forming an air gap channel there between. Means are provided for coolant flow along an outside surface of the condensation structure so that distilled water will condense on the condensation structure for collection from the air gap channel.

Abstract: A surgical device controls the temperature of an organ such as a kidney during minimally invasive surgery. The device includes a number of chambers fed by a fluid port. At least one of the chambers includes one or more baffles so that a cooling fluid entering through the fluid port is selectively distributed in a desired manner about an enclosed organ. The device may be fabricated of materials that can be rolled, folded, or otherwise compressed into a form suitable for delivery to a minimally-invasive surgical site.
