  • Patent number: 9261620
    Abstract: System and method for deploying multiple antennas in an array configuration with unobstructed electromagnetic access to a formation outside of a casing, sequencing the transmitted signal to control the direction of transmission into the formation, receiving the reflected signals, and locating the position of the reflection based on the scanned transmission signal orientation and the direction of the received signal. Such a deployment of an antenna array with unobstructed electromagnetic access to the formation outside of the casing, sequencing of the interrogation signal, and analysis of the received signal relative to the transmitted signal direction form the basis for reflection image rendering as the transmitted signal is scanned by a sequenced stimulus signal.

  • Patent number: 7399504
    Abstract: The present invention relates to a method for preparing polymeric films, preferably electroactive films, with enhanced physical properties by the steps of applying to a substrate a solution of a polymer containing pendant labile solubilizing groups, then removing the solvent and a sufficient concentration of the labile solubilizing groups render the polymer less soluble in the solvent than before the labile groups were removed. It is believed that the removal of pendant soluble groups a) permits optimization of the semiconducting backbone for charge transport performance, b) allows direct control of microstructure in the final film, and c) renders the final film more robust during subsequent process steps needed to construct multilayer devices.
