A cutting system includes knives attached to a continuously moving belt-type carrier. The carrier motion moves the knives past stationary counterknife fingers which are attached to or uniform with a cutterbar, as the cutting system is driven through a field of crop stalks, which are cut by the interaction between the knives and counterknives. One or more sensing devices produce signals or images related to the condition of the knives when the knives are moving past the sensing devices. A processing unit processes the signals or images and derives therefrom one or more parameters representative of the condition of the knives, and compares the parameters to a reference, to thereby monitor the condition. An agricultural implement such as a combine harvester, can be equipped with the cutting system.

Methods and systems of heating a substrate in a vacuum deposition process include a resistive heater having a resistive heating element. Radiative heat emitted from the resistive heating element has a wavelength in a mid-infrared band from 5 μm to 40 μm that corresponds to a phonon absorption band of the substrate.
