    摘要: A mesh network is initiated by using multiple frequency bands for establishing communication between mesh nodes. In one aspect, a higher or lower frequency communication link may be established depending on the range between two mesh nodes. As the mesh network increases and decreases in density, and range and communication aspects change, a communication link may be change between the higher and lower frequency bands as necessary.

    摘要: The invention relates to liquid crystalline emitter and charge-transport materials for use in organic light emitting devices. These materials may be used as uncrosslinked liquid crystalline glasses or crosslinked as insoluble polymer matrices. The polymer may be formed by photopolymerization. The polymerization may be done without a photoinitiator. The polymer may have a room temperature nematic phase that may be stabilized the nematic phase relative to smectic phases. The polymer may be easily photocrosslinked with a high final degree of polymerization. The layers of crosslinked layers organic semiconductor may be incorporated into electronic devices. The materials have a high luminous output. Exemplary light emitting polymer may be formed by the polymerization of a reactive mesogen having the formula: B1—S1-T1-(F-T2)p-F-T3-S2—B2, wherein B1 and B2 are polymerizable end groups, F is a fluorene functional unit, S1 and S2 are spacer units, and T1, T2, and T3 are thienothiophenes units.
