摘要： An approach is provided that uses diversity to compensate fading of free-space optical (FSO) signals propagating through an environment characterized by atmospheric scintillation. One embodiment involves collecting at least one FSO beam, demultiplexing the beam by wavelength into at least two sub-beams, detecting each sub-beam to produce an electrical output therefrom, and recovering a signal using complementary information from at least two of the electrical outputs. Another embodiment involves collecting the FSO beam onto an array of spatially separated sub-apertures, detecting the light entering each sub-aperture to produce an electrical output therefrom, and recovering a signal using complementary information from at least two of the electrical outputs. This second embodiment enables both electronic adaptive processing to coherently integrate across the sub-apertures and in the case of multiple transmit apertures a free space optical Multiple Input Multiple Output (MIMO) system.

摘要： A composite dielectric material having a plurality of particle cores, each surrounded by polymer strands that are chemically bonded to the surface of the particle core. Each polymer strand includes a linker, through which the polymer strand is attached to the surface, an interfacial core-shielding (ICS) group bound to the linker, and a polymer molecule bound to the ICS group. The ICS groups are designed to inhibit electrical breakdown of the composite dielectric material by (i) deflecting or scattering free electrons away from the particle cores and/or (ii) capturing free electrons by being transformed into relatively stable radical anions. Representative examples of the particle core material, linker, ICS group, and polymer molecule are titanium dioxide, a phosphonate group, a halogenated aromatic ring, and a polystyrene molecule, respectively.

摘要： With the advent of communication devices including Global Positioning capability, for example, mobile communications networks and GPS may be coordinated to determine where a user is located and to reserve capacity in the mobile communications network should the user need to make a call. Example Embodiments include the GPS being used to locate a user and compute a movement vector of that user in order to predict future locations, e.g., a next cell where the user will be located, at which the communications network may reserve appropriate capacity for that user. This service may be used by emergency service workers or government officials who need to communicate in times of emergency or when network overloads occur. Premium service callers who would like to ensure that their calls get through may also use this service for an added fee.

摘要： The present disclosure pertains to a system configured to prepare and use prediction models for software diversification. Some embodiments may: obtain compilation data; identify a plurality of blocks from the compilation data; and pad each of one or more blocks of the plurality of blocks by a random amount such that executable instructions within the each block begin at a different location to prevent a deterministic memory addressing attack, none of the one or more blocks being a beginning block of the compilation data.

摘要： Methods for systems are described for communicating an optical data signal. An example method may comprise receiving a data signal comprising a first level indicative of an upper end of a power range of the data signal and a second level indicative of a lower end of the power range of the data signal. The example method may comprise modulating the data signal to generate a modulated data signal. The modulated data signal may comprise the first level modulated with a first beacon tone and the second level modulated with a second beacon tone. The second level may be modulated in phase with the first level. The method may comprise transmitting an optical signal comprising the modulated data signal.
