  • Patent number: 12285580
    Abstract: This invention provides parasitic millirobots that can effectively adapt to an unstructured environment and coherently interact with diverse objects in order to fulfil various application needs. Particularly, a minimalist millirobot construction strategy by splashing composited agglutinate magnetic spray (M-spray) is adopted, which is capable of self-turning multifarious milli-/centi-objects into parasitic millirobots on-demand. Through taking full advantage of the objects' inherent structure and a covered thin drivable film, the M-spray demonstrates superior handling (from 1-D to 3-D structures) and loading capabilities (up to thousand-fold and hundred-fold of its volume and weight, respectively) while with neglectable size increment (as low as 1%) to target.

  • Patent number: 12059700
    Abstract: Systems and methods for coating a thin film with a viscous material, such as a liquid, a paste, or an adhesive, at a desired thickness. In such a system, two films move adjacent to one another, optionally in opposite directions, atop two rollers separated by a known gap that defines a coating thickness, with the material being transferred from one film to the other. The rollers may be maintained in their relative positions by springs and/or linear actuators and positioned using linear encoders. In alternative arrangements, the material to be coated could be low viscosity material such as a polymeric solution. Air knives may be provided near the gap to create an air flow that aids in preventing the free flow of low viscosity materials outside the bounds of the film during coating.

  • Patent number: 11965251
    Abstract: A fluid tight, fully-densified, coating is prepared by a High Velocity Oxygen Fuel (“HVOF”) process that dilutes oxygen with an inert gas. The inert gas is pre-mixed with oxygen prior to the oxygen entering a combustion chamber. The resultant flame temperature is lowered a controlled amount to eliminate, minimize or reduce oxidation of power feedstock that is injected into the thermal spray torch. The ability to reduce the flame temperature allows a relatively smaller particle feedstock to be deposited without significant oxidation. The dilution process creates an as-deposited fully-dense, fluid tight coating.
