A recorder for recording and playing back information. The recorder is particularly useful in vehicles such as aircraft and space vehicles. The recorder has no moving parts and has a plurality of power levels. The recorder has the capability of detecting errors in its memory and to avoid using portions of the memory that have errors. The recorder has multiple channels that can be programmed for input or output use. On demand memory assignment capability permits maximum use of the memory array.

The non-linear conductance and capacitance characteristics of electrically non-homogenous materials over a given frequency range are used to identify and analyze such materials.

Identification of materials using their complex dielectric response

The non-linear conductance and capacitance characteristics of electrically non-homogeneous materials over a given frequency range are used to identify and analyze such materials.

The type of conductor, its property, and if a metal, its type and cross-sectional area can be obtained from measurements made at different frequencies for the amount of unbalance created in a previously balanced stable coil detection system. The true resistive component is accurately measured and thus reflects only the voltage loss attributable to eddy currents caused by introduction of the test sample to the coil system. This voltage divided by corresponding applied frequency gives a curve which peaks at a frequency dependent upon type of conductor. For a metal this peak frequency is proportional to the samples resistivity divided by its cross-sectional area.
