摘要:
The present teachings are directed toward an electrocatalytic cell including a barrier, having at least a first side and a second side opposite the first side, comprising a material permeable to oxygen ions and impermeable to at least CO2, CO, H2, H2O and hydrocarbons, an electrical power supply in communication with the barrier, a catalyst adjacent the first side of the barrier, a supply of feedstock components in communication with the first side of the barrier, a supply of a carrier gas component in communication with the second side of the barrier; wherein the feedstock components contact the catalyst and react to form hydrocarbon-containing components and oxygen-containing components, and the electrical power supply biases the barrier to thereby conduct oxygen ions from the first side to the second side. Also presented are a device and methods for producing carbon nanotubes.

Methods and systems for determining that a device is currently within a given context are described. A device may include multiple sensors coupled to the device. A sensor utility value combining a rate of power consumption for a sensor and an accuracy score indicating a degree to which the sensor may provide outputs indicative of the device being currently in the given context may be determined for each sensor. Based on sensor utility values, the multiple sensors coupled to the device may be ranked. A sensor may be identified based on a ranking of the sensor. A probability associated with a determination that the device is currently within the given context may be assigned to the sensor. More sensors may be identified to determine with increasing probability and increasing power requirements that the device is currently within the given context.
