A system usable to adapt an optical device to calculate a condition value. The system utilizes data from an optical device about a field of vision to calculate a condition value such as temperature for a target within the field of vision. The system makes use of an adapter connected to the optical device for transmitting adapter output data and a converter that accesses the adapter output data to calculate the condition value. The adapter components can weigh less than 3 ounces, and encompass a volume of less than 4 cubic inches, making it suitable for deployment on a drone, or remotely operated vehicle.

At least some aspects of the present disclosure feature an RF hydration sensor in an assembly, comprises a substrate; an antenna disposed on the substrate; an RF circuit electrically coupled to the antenna; a thermal source electrically coupled to the RF circuit for changing a thermal condition of a target area; and a sensing element thermally coupled to the thermal source for sensing a temperature of the thermal source. The RF hydration sensor wirelessly receives a power from a remote transceiver and provides at least part of the power to the thermal source.

A method for determining residual moisture on and/or within a lens forming surface of a mold half includes the steps of carrying out an infrared inspection of at least a central portion of the lens forming surface of the mold half with the aid of an infrared camera, collecting measurement values resulting from the infrared inspection, which represent a degree of residual moisture on and/or within the lens forming surface, comparing the collected measurement values with a predefined threshold value representing a maximum tolerable residual moisture on and/or within a lens forming surface of a reference mold half, and, upon detection of an exceedance of the predefined threshold value representing the maximum tolerable residual moisture, preventing the inspected mold half from being used further.
