Abstract: Clock synchronization error is corrected or minimized by fitting a parabolic f(T) function to the crystal's data, and compensating for sampling period drift in an Analog to Digital Converter (ADC) at various temperatures.

Abstract: A system and methods for monitoring, acquiring, and recording acoustic data configurable for low-power operation. Embodiments of the system configured for low-power operation, advantageously may be deployed in remote environments for extended periods of time. Embodiments of the system may include an audio processor configured for low power operation and may include a microcontroller operably coupled to audio processor and a storage device. Additional embodiments may include a housing configure to withstand harsh environments for extended periods of time.

Abstract: The invention relates to a method for injecting reducing agents into a shaft furnace in which the reducing agent is transported within a pneumatic delivery stream to the shaft furnace according to the flowing steps; a) dividing the delivery stream into a number of partial streams, b) transferring the individual partial streams through a heating unit, and c) heating the reducing agent within the individual partial streams inside of the heating device. A device for carrying out the inventive method comprises, for example, a delivery line in order to pneumatically deliver the reducing agent to the shaft furnace, and a number of heat exchange pipes which are integrated in the delivery line using a parallel connection, said connection relating to flow techniques, such that the pneumatic delivery stream is divided into a number of partial streams. The inventive device also comprises a heating unit for transmitting heat energy to the individual partial streams.

Abstract: A pneumatic mixture which has a relatively high content of pulverulent materials in the propulsion air is formed in a single metering means. This mixture is propelled through a common primary pipe to a distribution head in which the mixture is divided into secondary currents which are delivered respectively to each of the injection points. A supercritical speed is imparted to the mixture in the distribution head.
