  • Patent number: 11115902
    Abstract: Methods, systems, and devices for wireless communications are described. A device may communicate with a second device, which may be a Bluetooth device, using a relay profile (e.g., a low energy (LE) isochronous (ISO) relay profile). In accordance with broadcast discovery signaling by the device and decisions made by the Bluetooth device, the device may synchronize to a broadcast isochronous stream (BIS) from another device. The device may then establish a communication link with the second device (e.g., a synchronous connection oriented (SCO) link, an enhanced synchronous connection oriented (eSCO) link, an asynchronous connection less (ACL) link) to be used for relay of the BIS. The device may then convert, based on the relay profile, broadcast isochronous data packets of the BIS to SCO packets, eSCO packets, and/or ACL packets, and relay the converted packets to the second device via the established communication link.

  • Patent number: 8340526
    Abstract: Systems and methods for a reconfigurable, long-range, underwater data-communication network are described. The network provides a low cost, low power, lightweight, and easy to deploy underwater communication system capable of being operated at long distances. The network may include a cabled ocean observatory, which may be deployed underwater and connected to a surface buoy. The cabled ocean observatory may be connected to one or more removable underwater sensors via fiber optic cables. The underwater sensors may be disposed at underwater locations at long distances from the cabled ocean observatory. Fiber optic extension modules may be permanently connected to each end of the fiber optic cables. Each fiber optic extension module may include an optical transceiver, a power supply, and an inductive element for removably coupling an underwater sensor or the cabled ocean observatory to the fiber optic cable.

  • Patent number: 8305227
    Abstract: The present invention provides a wireless auxiliary system for monitoring and control of an underwater installation. The auxiliary system of the present invention sends data and control signals between an underwater installation—for example, a lower stack 26 in a hydrocarbon drilling or production facility—and an associated riser assembly 23. Data is collected by sensor network 208A, 208B and is transmitted from a first transceiver 201 to a second transceiver 203 by electromagnetic signals. First transceiver 201 is powered by a local power supply 205. To conserve power consumption, the first transceiver is designed to become active for a short time and then to switch to an inactive mode. For example, wireless data transfer may occur after the detachment or just prior to the reattachment of riser assembly 23 to the underwater installation. Wireless data transfer may also occur on receipt of a handshaking signal from second transceiver 203.
