Assignee:

TRUE SOL INNOVATIONS, INC. - Seattle WA

International Classification:

H02J 1/00

US Classification:

307 80

Abstract:

Disclosed herein are systems and methods for providing power to a load. Systems according to the present embodiment may include an electrical generator to generate electrical power and a battery to store electrical power. The present disclosure may be applied to electrical power generators having variable outputs, and may be utilized to provide a more constant electrical output by drawing power from the electrical generator and the battery as necessary to satisfy the power requirements of the electrical load. The system draws power from the electrical power generator and the battery to satisfy the power requirements of the load. Based on a mode of operation, the system may draw power only from the battery, only from the electrical power generator, or from both the electrical power generator and the battery alternately.

H04B 7/0413

Abstract:

A wireless communication network such as a 5G communication network can use MIMO technologies to enhance bandwidth between a wireless communications base station and one or more user equipment devices within a service area of the base station. RF signal repeaters can be utilized to provide one or more additional physical channels for communication between the MIMO base station and the MIMO user equipment. These RF signal repeaters can be regarded as increasing the MIMO channel diversity within the ambient environment.

H01Q 25/00
H01Q 1/38

Abstract:

A switchable dual polarization patch antenna with improved cross polarization isolation to concurrently radiate horizontally polarized signals and vertically polarized signals. A planar conductor is arranged with a first terminal and a second terminal that are vertically spaced on a portion of the planar conductor to radiate a component of a vertically polarized signal with zero degrees of phase shift from one of the two terminals and radiate another component of the vertically polarized signal having a 180 degrees of phase shift from the other of the two terminals. A hybrid coupler can provide the 180 degrees of phase shift. A horizontally polarized signal is radiated from a third terminal that is horizontally spaced on another portion of the planar conductor and coupled to a horizontally polarized signal source. The direction of the 180 phase shift for the first and second components of the vertically polarized signal may be selected. Also, a direction for a phase shift for the horizontally polarized signal may be selectable.

International Classification:

H01Q 1/52
H01Q 1/36
H01Q 9/04
H01Q 3/24

Abstract:

A switchable patch antenna comprises a planar conductor having an aperture (hole) formed in the middle of the planar conductor. Radiation of a sinusoidal signal is controlled by comparison of separate impedance values for two components that have separate impedance values. Each of the two components have one end coupled together at the terminal positioned at a center of the aperture and their other ends separately coupled to opposing edges of the aperture. A sinusoidal signal source is also coupled to the terminal positioned at the aperture's center. Further, when the impedance values of both components are substantially equivalent, radiation by the antenna of the provided signal and/or mutual coupling of other signals is disabled. Also, when an impedance value of one of the two components is substantially greater than the other impedance value of the other component, the provided signal is radiated and/or mutual coupling is enabled.

International Classification:

H01Q 1/02
H01Q 1/36

Abstract:

The invention compensates for abnormal operating temperatures and/or abnormal behaviors of a holographic metasurface antenna (HMA) that is generating a beam based on a holographic function. The HMA is characterized with different holographic functions for a plurality of operating temperatures and a plurality of behaviors during the manufacturing process. The characterization of the HMA identifies different hologram functions that cause the HMA to generate more or less heat or exhibit more or less abnormal behavior while generating equivalent beams. Further, or more characterizations of a hologram function may be performed remotely after the HMA is installed in a real world environment. An operating temperature and/or a temperature gradient may be detected by temperature sensors physically located on a circuit board for the HMA.

H04B 7/08

Abstract:

A system for evaluating the performance of beam forming antennas based on correlations of signal to noise measurements of individual scattering elements in the antennas. A signal source provides a signal having a first frequency to an input of the antenna. Each of the antenna's scattering elements are individually selectable to radiate the signal. A control signal sequentially turns off and on each scattering element while radiating the signal. Also, a characteristic of the signal radiated by each scattering element is separately measured and each difference between the characteristics are identified and compared to one or more threshold values. A report regarding the differences that exceed the threshold value is provided to a user.
