Private data sharing system
A novel architecture for a data sharing system (DSS) is disclosed and seeks to ensure the privacy and security of users' personal information. In this type of network, a user's personally identifiable information is stored and transmitted in an encrypted form, with few exceptions.

Phase-noise mitigation at high frequencies in 5G and 6G
As 5G, and especially 6G, push into ever-higher frequencies, phase noise presents an increasing problem. Disclosed are procedures and modulation schemes to mitigate phase noise and permit messaging at higher frequencies. Each modulation scheme provides phase-noise immunity by configuring modulation states with large phase acceptance regions. A message element is faulted if its sum-signal amplitude or phase is in an exclusion zone. Modulation schemes with fewer phase levels, more amplitude levels, and very broad phase acceptance regions are necessary for high frequency operation where phase noise dominates. Using allowed states with the maximum amplitude modulation in both branches can provide nearly 90-degree phase acceptance. Requiring that the two branches be equal provides nearly 180-degree phase acceptance. Further requiring that the amplitude levels be positive can provide total phase-noise immunity, with a 360-degree allowable phase range. Embodiments can thereby enable high frequency communication despite phase noise. |

Decoupled inner slot antenna
In the design of phased array antennas, as well as simple use of compact antennas, there is a strong interest to locate higher frequency antennas closer in spacing, and/or on the same surface, as the larger frequency antennas. What is needed is an array antenna technology, which can be conformal, and can interleave elements, as the frequency increases, to reduce array grating lobes. The desired solution would have much fewer required RF antenna ports, than the Tightly Coupled Dipole Antenna solutions. The optimal solution would also enable Dual or Diverse Polarization. This innovation embeds a wideband Slot Antenna, within the physical area of a larger electric dipole Antenna or Cross Dipole Antenna, with a De-Coupling gap around the Slot Ground Plane (or conductor) and isolates the Wideband Slot Antenna (the inner antenna) from the Dipole or Monopole antenna leg(s) (the Outer Antenna). Both (Inner and Outer) antennas have independent feeds and independent transmission line(s). Two key innovations are the use of a De-Coupling gap, and the use of the patent pending innovation “Compact Single Pole Wideband Slot Antenna Design with Inverted Co-Planar Waveguide Feed”. Both the Inner Slot Antenna and its CPW feed are independent and isolated from the Outer Antenna and its feed and transmission line. This structure, which could have a multiplicity of inner Slot Antennas with numerous RF ports, is very different from the slot or parasitic inner structure within a single port antenna system. |

Gradient permittivity film
A gradient permittivity film comprises (a) a first permittivity layer comprising a first continuous matrix of a first material having a first relative permittivity (εr1) and a second component having a second relative permittivity (εr2) dispersed in the first continuous matrix, the first permittivity layer having a first effective layer relative permittivity (ε1) and a thickness (T1); and (b) a second permittivity layer having a second effective layer relative permittivity (ε2) and a thickness (T2) disposed on the first permittivity layer T1=0.8(t1) to 1.2(t1), where t1=(I); T2=0.8(t2) to 1.2 (T2), where T2=(II). t 1 = c 4 f ε 1 ( I ) t 2 = c 4 f ε 2 ( II ) |

Ring-shaped antenna and ear module comprising same
Disclosed are: a ring-shaped antenna which is formed in the form of a ring mounted between the housing of an ear module and the outer circumference of a coin-shaped battery and communicates with an antenna, mounted on another ear module, via NFMI; and a wireless earphone comprising the ring-shaped antenna. The disclosed ring-shaped antenna comprises: a first terminal sheet and a second terminal sheet, each extending from one side of a base sheet and having a terminal formed thereon; a plurality of front radiation patterns disposed apart from one another on the front surface of the base sheet; and a plurality of rear radiation patterns disposed apart from one another on the rear surface of the base sheet, wherein the plurality of front radiation patterns and the plurality of rear radiation patterns are connected through via-holes and thereby form an antenna pattern wound in the vertical direction of the base sheet. |
