Abstract:

According to one embodiment, an antenna cooling system, comprises a first cylinder and a second cylinder substantially concentric to the first cylinder. The first and second cylinders form a chamber between the first cylinder and the second cylinder. The chamber is configured to receive a fluid flow. A plurality of fins are disposed within the chamber and rigidly coupled to the first cylinder and the second cylinder. The plurality of fins are configured to transmit thermal energy to the fluid flow. A plurality of ports are coupled to the second cylinder. Each port is configured to receive an antenna unit.

US Classification:

4351737, 4353061

Abstract:

According to one embodiment, the disclosure provides a system for algal cell lysis. The system may include at least one algal cell, a plurality of metal nanoparticles, and an electromagnetic radiation generator. The generator may be able to generate radio frequency or microwave radiation that excites the plurality of metal nanoparticles, resulting in lysis of the algal cell. The disclosure also provides a system for recovery of a lipid from an algal cell similar to the above system but also including a separator. The disclosure further provides a method of recovering a lipid from an algal cell by supplying a plurality of metal nanoparticles to at least one algal cell, exciting the plurality of metal nanoparticles with radio frequency or microwave electromagnetic radiation, lysing the algal cell to release the lipid, and separating the lipid from the lysed algal cell.

International Classification:

H01Q 3/00
H01Q 19/06

US Classification:

342377, 343754

Abstract:

An array of geodesic lens antennas (GLAs) comprises multiple vertical radiating slots, each formed into an annulus, which are individually controlled by feeding rings. One feeding ring is provided for each of the GLA elevation elements, resulting in multiple, parallel waveguide channels that together enable elevation beam steering, thus forming a concentric stack of geodesic lenses. Accordingly, exemplary embodiments of the invention are capable of RF beam formation in azimuth and elevation by using these lenses to form, shape, and steer one or more RF beams. Each GLA in the stack forms an element in the elevation plane with separate amplitude and phase control, providing the degrees of freedom required to independently and simultaneously control azimuth and elevation beam forming and steering.

US Classification:

342372, 342373, 342383

Abstract:

According to one embodiment, generating an array correlation matrix includes interfacing with an antenna system that has antenna elements. The antenna elements receive incoming signals, and each antenna generates a response signal in response to receiving the signals. The following is performed for a number of iterations to yield summed signals: controlling weights of the antenna elements to weight the response signals; and receiving a summed signal comprising a sum of the weighted signals. An array correlation matrix is generated from the summed signals.
