Abstract: The present invention describes methods of identifying stimulants for the biogenic production of methane in hydrocarbon-bearing formations. Methods involve the use of microbial nucleic acid sequence information for the determination of gene products that are enzymes in a variety of pathways involved in the conversion of hydrocarbons to methane. Enzymes and stimulants identified by invention methods can be used in processes for enhancing biogenic methane production, for example, by addition to coal seams and coalbed methane wells.

Abstract: A method of controlling a motor operating a pumping apparatus of a fluid-pumping application. The pumping apparatus includes a pump having an inlet to receive a fluid and an outlet to exhaust the fluid, and the motor coupled to the pump to operate the pump. The method includes the acts of controlling the motor to operate the pump and monitoring the operation of the pump. The monitoring act includes monitoring a power of the motor, and determining whether the monitored power indicates an undesired flow of fluid through the pump. The method further includes the act of controlling the motor to cease operation of the pump when the determination indicates an undesired flow of fluid through the pump and zero or more other conditions exist.

Abstract: An electronic audio device, such as a radio having an audio loudspeaker is described, as well as a method of operation of such a device. The device has an audio stage (6) having an audio output for providing an audio output signal, an acoustic transducer (12) coupled to the audio output for outputting an acoustic signal and a microphone element (13) acoustically coupled to the acoustic transducer to provide a feedback signal representative of the output of the acoustic transducer. A comparison circuit (15) compares parameters of the audio output signal and parameters of the feedback signal; and a control circuit (16, 24, 50) responsive to the comparison circuit controls the audio stage when a parameter of the feedback signal differs from that parameter of the audio output signal by a predetermined amount.
