Patent number: 10801966Abstract: A method and testing apparatus determine receding contact angles of liquids on surfaces by depositing a liquid in a manner whereby the volume of the drop is increased through stepwise addition of smaller drops. Each increment of volume growth causes the perimeter of the drop to advance across the surface. The incremental volume elements impart sufficient energy to the growing drop such that the drop perimeter expands beyond its equilibrium diameter for that volume. The drop perimeter tends to contract between volume additions as the excess energy is dissipated. The method and testing apparatus determine the receding contact angle between the incremental volume additions.Type: GrantFiled: October 26, 2015Date of Patent: October 13, 2020Assignee: BRIGHTON TECHNOLOGIES LLCInventors: Raymond Giles Dillingham, Brietta Rose Oakley, Lucas Hale Dillingham, Andrew Davis Gilpin, Francis Charles Ganance, Timothy James Barry, Harun Mohammed

Patent number: 10794701Abstract: An inertial sensor includes a movable element having a mass that is asymmetric relative to a rotational axis and anchors attached to the substrate. First and second spring systems are spaced apart from the surface of the substrate.
