Abstract: The present invention relates to a polymer latex for dip-molding applications obtainable by free-radical emulsion polymerization of a mixture of ethylenically unsaturated monomers comprising at least one conjugated diene and at least one ethylenically unsaturated nitrile compound in an aqueous medium in presence of seed latex particles having a glass transition temperature (mid point temperature Tmg) measured by DSC according to ASTM D3418-03 of ?50° C. to 50° C. wherein the seed latex particles do not contain structural units derived from ethylenically unsaturated nitrile compounds, to a method of preparing said polymer latex, to articles made by using said polymer latex and to a method for preparing dip-molded articles from said polymer latex.

Abstract: A system includes a camera configured such that a field of view of the camera is positioned to capture a base portion and a movable portion of an aircraft. A computer communicatively connected to the camera is configured to determine a relative orientation between a base identification feature of the base portion and a movable identification feature of the movable portion of the aircraft based on image data received from the camera. The computer is also configured to determine a position of the movable portion of the aircraft based on the relative orientation between the base identification feature and the movable identification feature and a position of the base portion and to compare the position of the movable portion to a reported position for the movable portion to determine a variance. An aircraft control system is configured to monitor a state of the aircraft based on the variance.

Abstract: An unmanned aircraft system includes a testing and calibration system that enables automated testing of movable parts of an unmanned aircraft. The testing and calibration system uses a camera-based technique to determine the position and angle of movable parts, in order to establish whether or not those parts are moving in a manner consistent with correct function.
