An audio conference system for automatically forming a single combined physical microphone array aperture across associated and/or disassociated ad-hoc microphone elements in a shared 3D space is provided. The audio conference system includes a plurality of microphone/speaker units, each including at least one microphone and/or at least one speaker and a system processor communicating with the microphone/speaker units. The system processor instructs the microphone/speaker units to transmit unique calibration signals sequentially or simultaneously and to calculate time difference of arrival (TDOA) between the microphone/speaker units. A physical array structure of the microphone/speaker units is obtained based on TDOA between the microphone/speaker units, and a consolidated target coverage zone common to the microphone/speaker units is generated based on the physical array structure.

System for dynamically determining the location of and calibration of spatially placed transducers for the purpose of forming a single physical microphone array

This application is related to a system and methods for sampling fluids and gases using nuclear magnetic resonance (NMR) technology. Specifically the system is related to an improved metallic pipe design for use at oil and gas well heads that includes integral coils for transmitting an NMR pulse sequence and detecting NMR signals and can be used as a component of an NMR instrument. The methods are related to obtaining and analyzing NMR spectra in stationary and flowing states.
