20120116023 | METHOD FOR CONTROLLING ANIONIC POLYMERIZATION - This invention deals with an approach to control anionic polymerization. The anionic polymerization is conducted by adding a kind of initiator ligand compound, directly or in the form of solution into the monomer or initiator at the same or different time, or at different stages. The metal atoms in the ligand can form the association with the initiator cations, while the alkyloxy groups in the intiator ligand can restrict the entering channel of the addition of the monomers due to their relatively large volume or steric hindrance. Therfore, the initiator ligand compound can restrict the rate of anionic polymerization, restrain the side reaction, and make the anionic polymerization possible to be conducted at room or even higher temperature. | 05-10-2012 |

20130187091 | LIQUID CRYSTAL BLUE PHASE - Methods of forming a liquid crystal blue phase from composite materials comprising a chiral nematic liquid crystal host and an azobenzene-based bent-shape molecule are described. The composite materials quickly transfer from the liquid crystal blue phase to an isotropic phase under electromagnetic radiation and transfer from the isotropic phase to the liquid crystal blue phase when electromagnetic radiation is removed. | 07-25-2013 |
20130337197 | LIQUID CRYSTAL BLUE PHASE - Methods of forming a liquid crystal blue phase from composite materials having a chiral nematic liquid crystal host and a bent-shape molecule are described. The stable temperature range of the liquid crystal blue phase may be improved by controlling the thickness of the composite materials. For example, a given composition may have a maximum stable temperature range for the liquid crystal blue phase at about 1 μm. | 12-19-2013 |

20130016854 | MICROPHONE ARRAY PROCESSING SYSTEM - An audio system is provided that employs time-frequency analysis and/or synthesis techniques for processing audio obtained from a microphone array. These time-frequency analysis/synthesis techniques can be more robust, provide better spatial resolution, and have less computational complexity than existing adaptive filter implementations. The time-frequency techniques can be implemented for dual microphone arrays or for microphone arrays having more than two microphones. Many different time-frequency techniques may be used in the audio system. As one example, the Gabor transform may be used to analyze time and frequency components of audio signals obtained from the microphone array. | 01-17-2013 |
