Abstract: One or more embodiments relates to compositions, method of using and methods of producing a gas mixture. The method includes supplying a composition LaxSryCozMwO3, where x ranges from 0.5 to 1, y ranges 0.0 to 1-x, z ranges from 0.1 to 1.0, and M is a dopant or dopants where w ranges from 0.0 to 1-z; and energizing the composition directly using electromagnetic energy to heat the composition to a temperature above 700° C. The method further includes contacting the composition with a reactant gas mixture comprising methane and an oxidant forming a product gaseous mixture.

Abstract: An automatic H-register clear system for the prevention of erroneous convolution in adaptive digital echo cancellers is disclosed. Incoming signals from the H-register are accumulated and compared to a predetermined threshold value and when the value is exceeded, the H-register is cleared with the occurrence of the internal housekeeping cycle of the echo canceller. The clearing of the H-register allows a new impulse response model to be generated from new sampled data. In one embodiment using analog implementation, the accumulation takes place using a sequence of signal processing of digital-to-analog conversion, full wave rectification followed by integration of the signal. In another preferred embodiment using a counter detection system, each word is compared to a threshold and if this value is exceeded, a counter is indexed. If the value of the count in the counter exceeds a predetermined number during the sampling interval, the H-register is cleared.
