  • Patent number: 8401385
    Abstract: A large communication network suitable for nationwide or worldwide utilization. The present invention overthrows the conventional packet switching technologies with an all-optical network. The invention uses tunable laser sources to generate large number of highly stable narrow-band optical signals, each serving as a communication channel. With packet processing replaced by all-optical channels, the network become highly secure and scalable while harnessing the virtually unlimited capacity of fiber-optic. A large number of nodes (called area code nodes) are connected with all-fiber-optic links with all-optical switches. A routing algorithm provides one or more communication links from each area code node to every other area code node so that information never has to change carrier wavelength as it travels the network. Each area code node contains circuits that are provided to connect individual users to the network.

  • Patent number: 8098764
    Abstract: Millimeter wave radio with phase modulation. In preferred embodiments each of the two radios in a link uses a single aperture to transmit radiation in one of the two bands, and receive radiation in the other of the bands. The counterpart radio used to form a link preferably is almost identical, except for the interchange of the transmit and receive frequencies. Preferred embodiments utilize a modulation scheme in which the radios each receive on-off keyed data and transmit the on-off keyed data encoded in a millimeter wave carrier wave with binary phase shift keying.

  • Publication number: 20100227022
    Abstract: A longevity drink and method for providing same requires the collection of waters from various global regions. Specifically, water portions without additives are collected from separate and distinct global regions, with the different regions being located more than one thousand nautical miles distant from each other. The various portions are then transported to a processing point where they are combined. In combination, each portion has a substantially same liquid volume. The combination of waters (elixir) is then packaged and distribution to consumers for consumption as a longevity drink.

  • Patent number: 7777961
    Abstract: A method and system for creating and co-aligning a first array of optical beams with a second array of optical beams. In a preferred application the invention is used in a cross connect optical switch. A first set of alignment beams are created and added to and aligned co-axially with each of the first set of parallel collimated cross-connect communication beams. A second set of alignment beams are created and added to and aligned co-axially with each of the second set of parallel collimated cross-connect communication beams. A preferred embodiment includes an injection unit with a “point” infrared light source such as a vertical cavity surface emitting laser (VCSEL) operating in the near infrared at 850 nm and having a divergence of about 30 degrees. The beam from this source is collimated with collimator optics to produce a collimated beam with a cross sectional dimension of about 16 millimeter×16 millimeters. This collimated beam is separated into 128 separate beams with a mask having 128 0.

    Abstract: An automatic celestial navigation system for navigating both night and day by observation of K-band or H-band infrared light from multiple stars. One or more telescopes mounted on a movable platform such as a ship or airplane and directed at a substantially different portion of sky. Telescope optics focus (on to a pixel array of a sensor) H-band or K-band light from one or more stars in multiple telescopic fields of view. Each system also includes a GPS sensor and a computer processor having access to catalogued infrared star charts. The processor for each system is programmed with special algorithms to use image data from the infrared sensors, position and timing information from the GPS sensor, and the catalogued star charts information to determine orientation (attitude) of the platform.
