  • Patent number: 10291316
    Abstract: Radio communications systems use 100 to 200 satellites in random low-earth orbits distributed over a predetermined range of north and south latitudes. The satellites themselves create a radio route between ground stations via radio links between multiple satellites by virtue of onboard global navigation satellite system circuitry for determining the location of the satellite and route creation circuitry for calculating in real time the direction from the satellite's location at a particular instant to a destination ground station. Directional antennas in the satellites transmit routing radio signals to enhance the probability of reception by other satellites. One embodiment facilitates the creation of satellite-to-satellite links by assigning each satellite a unique identifier, storing orbital information defining the locations of all of the orbiting satellites in the system at any particular time, and including in the radio signal the unique identifier associated with the transmitting satellite.

  • Patent number: 10135521
    Abstract: An embodiment of the present invention is a system to maximize efficiency as a mobile terminal receives data signals transmitted through multiple satellite spot beams. The multiple spot beams can be broadcast via a single satellite or multiple satellites. As a mobile terminal travels throughout a region, the system determines which spot beam would delivers data in the most efficient manner possible. This system takes into account multiple factors, including but not limited to velocity of the mobile terminal, traffic within a spot beam, business affiliations, etc. Once the system takes into account the various factors, an embodiment of the present invention generates a relative weighted factor that is subsequently associated with various available spot beams. Based on rankings of the weighted factors associated with each spot beam, the system may choose to receive data from a different spot beam.

An aircraft position, an aircraft velocity, and an aircraft direction are determined. For each candidate cell of a number of candidate cells, a level of beam distortion that would result from a beam directed from the candidate cell to the first aircraft is predicted. The target cell is selected from the candidate cells by identifying which of the candidate cells has a least amount of predicted beam distortion. The target cell is then signaled to prepare for a handover of responsibility for serving the wireless communication equipment.

    Abstract: Techniques for supporting communication in a heterogeneous network are described. In an aspect, communication in a dominant interference scenario may be supported by reserving subframes for a weaker base station observing high interference from a strong interfering base station. In another aspect, interference due to a first reference signal from a first station (e.g., a base station) may be mitigated by canceling the interference at a second station (e.g., a UE) or by selecting different resources for sending a second reference signal by the second station (e.g., another base station) to avoid collision with the first reference signal. In yet another aspect, a relay may transmit in an MBSFN mode in subframes that it listens to a macro base station and in a regular mode in subframes that it transmits to UEs. In yet another aspect, a station may transmit more TDM control symbols than a dominant interferer.

  • Patent number: 9462107
    Abstract: A smart phone senses audio, imagery, and/or other stimulus from a user's environment, and acts autonomously to fulfill inferred or anticipated user desires. In one aspect, the detailed technology concerns phone-based cognition of a scene viewed by the phone's camera. The image processing tasks applied to the scene can be selected from among various alternatives by reference to resource costs, resource constraints, other stimulus information (e.g., audio), task substitutability, etc. The phone can apply more or less resources to an image processing task depending on how successfully the task is proceeding, or based on the user's apparent interest in the task. In some arrangements, data may be referred to the cloud for analysis, or for gleaning. Cognition, and identification of appropriate device response(s), can be aided by collateral information, such as context. A great number of other features and arrangements are also detailed.

  • Patent number: 9284074
    Abstract: The invention relates to a method, a satellite, and a system or an arrangement with at least one satellite for detecting flying objects that are located in the vicinity of a planet, planetoid or similar celestial bodies. The invention further relates to the use thereof for carrying out said method and particularly to a constellation of LEO satellites (LEO=Low Earth Orbit) as an early warning of ballistic missiles, wherein said constellation comprises only satellites on equatorial orbits or orbits with low inclination. Satellite constellations in the low earth orbit (LEO) for missile detection are used for early warning of ballistic missiles, either by detecting the combustion phase of the flying object or by detection during the free-flight phase. The viewing direction of the sensors can be directed directly toward the earth or at an angle past the atmosphere.

  • Patent number: 9281896
    Abstract: Disclosed embodiments may help a balloon network to provide substantially continuous service in a given geographic area. An example method may be carried out at a balloon that is at a location associated with the first geographic area in a balloon network that includes a plurality of geographic areas. The balloon may determine that it should update its balloon-state in accordance with a balloon-state profile for the first geographic area. Then, in response, the balloon may determine the balloon-state profile for the first geographic area, which may include one or more state parameters for balloons operating in the first geographic area. The balloon may then operate according to the balloon-state profile for the first geographic area.
