Method for measuring electromagnetic properties
First Claim
1. A method of controlling an apparatus adapted for applying a coating to a member comprising the steps of:
- providing a transceiver proximate to a coated region of the member;
transmitting electromagnetic energy from an antenna of the transceiver to an area of the coated region;
receiving reflected electromagnetic energy at the antenna that has been reflected by the area of the coated region back to the antenna;
transmitting a signal, based upon the received reflected electromagnetic energy, from the transceiver to a controller of the apparatus; and
,controlling a manufacturing process parameter of the apparatus in response to the signal,whereby a property of the coated region of the member is maintained within a selected measurement range.

Abstract
A system and method is provided for measuring the electrical resistivity of a member without physically contacting the member. The system includes an electromagnetic energy transceiver having a transmitting and receiving antenna. The antenna is positioned in close proximity to the member being tested. Electromagnetic energy, such as microwave energy, is transmitted by the transceiver at the member being tested. Reflected electromagnetic energy is received at the antenna that has been reflected by the member hack to the antenna. The transceiver then generates an output that is proportional to the reflected electromagnetic energy and, thus, is proportional to the non-reflected electromagnetic energy absorbed by the member being tested. The output signal can thus be used to indicate resistivity of the member to electrical transmission. The output signal can be connected to a drive or controller of a high temperature coating system to increase or decrease electrical resistivity of the member while it is being manufactured to thereby control or maintain a predetermined electrical resistivity of the member at a desired quality.

14. A method of controlling application of a coating to a sheet material comprising the steps of:
-
providing a coating system adapted to apply the coating to the sheet material, the system having a drive adapted to move the sheet material as the coating is being applied; transmitting electromagnetic energy from an antenna of a transceiver to a portion of the sheet material having been coated by the coating; receiving reflected electromagnetic energy at the antenna that has been reflected by the portion back to the antenna; and controlling a manufacturing process parameter of the coating system based upon an amount of the received reflected electromagnetic energy such that application of the coating to the sheet material is adapted along a length of the sheet material to maintain a property of the coated sheet material within a selected measurement range. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
