Plural Receivers Only Patents (Class 342/465)
  • Patent number: 11070942
    Abstract: Systems and methods for determining user equipment (UE) locations within a wireless network using reference signals of the wireless network are described. The disclosed systems and methods utilize a plurality of in-phase and quadrature (I/Q) samples generated from signals provided by receive channels associated with two or more antennas of the wireless system. Based on received reference signal parameters the reference signal within the signals from each receive channel among the receive channels is identified. Based on the identified reference signal from each receive channel, an angle of arrival between a baseline of the two or more antennas and incident energy from the UE to the two or more antennas is determined. That angle of arrival is then used to calculate the location of the UE. The angle of arrival may be a horizontal angle of arrival and/or a vertical angle of arrival.

    Abstract: The embodiments described herein provide ranging capabilities in RF-opaque environments, such as a jungle, utilizing transponders located on a property line. In particular, the embodiments described herein provide for determining a perpendicular distance to a property line from a ranging device. The transponders are located on the property line and a separated from each other by a known distance. The ranging device transmits RF signals to the transponders, which are received by the transponders and re-broadcasted back to the ranging device on a different frequency. The ranging device uses information about the transmitted and received RF signals and the known distance to calculate a perpendicular distance from the ranging device to the property line.

  • Patent number: 9266532
    Abstract: The invention relates to a method for controlling the driving dynamics of a vehicle, especially of a single-track or dual-track and vehicle. The driving dynamics of the vehicle are controlled by way of brake and/or engine intervention, notably depending on a change of the movement of the vehicle in the three-dimensional space and relative to the earth coordinate system and depending on the effective direction of gravity or the earth's gravitational pull. According to said method, the attitude or orientation and the position of the vehicle in three-dimensional space and relative to the earth coordinate system is determined by means of a satellite navigation system (GNSS) which comprises a receiver, mounted on/in the vehicle, having at least three antennas for reception of satellite navigation signals and an inertial measuring system (INS), mounted on/in the vehicle, for measuring all changes in the movement, position and/or attitude of the vehicle.

  • Patent number: 9182484
    Abstract: Techniques are described that allow a system, such as a portable ADS-B-enabled device, to automatically determine whether the aircraft in which the system is employed is included in air traffic information (e.g., TIS-B air traffic information) broadcast by an air traffic control (ATC) ground station. The system includes a receiver assembly to receive a first transmission from a transponder of the aircraft that includes an identification address (e.g., an ICAO address) that identifies the aircraft. The receiver assembly also receives a second transmission from the ATC ground station that includes air traffic information and a client list including identification addresses of aircraft included in the air traffic information. The identification address of the aircraft is retrieved from the first transmission and used to determine whether the aircraft is included in the air traffic information by comparing the identification address with the identification addresses in the client list.

  • Patent number: 9124359
    Abstract: A system and method for minimizing or preventing interference between wireless networks is disclosed. A network hub broadcasts a beacon signal within repeating beacon periods. The position of the beacon signal shifts within each beacon period based upon a predetermined pseudo-random sequence. The beacon signal includes data identifying the current beacon shift sequence and the current phase of the sequence. Neighboring hubs independently or jointly determine and broadcast their own beacon shift sequences and phases for their respective networks from a predetermined list. Nodes connected with the network hubs are assigned allocation intervals having a start time that is set relative to the beacon signal. The start time and duration of the allocation interval wraps around the beacon period if the allocation-interval would otherwise start or continue in a next beacon period.
