a bidirectional repeater for repeating an electrical signal traversing a conductive line coupled between a gateway node and a sensor, the bidirectional repeater comprising a first input-output port coupled to the gateway node, a second input-output port coupled to the sensor, a first transceiver configured to receive a synchronization signal from the first input-output port and to transmit a resynchronized data signal to the first input-output port, a second transceiver configured to transmit the synchronization signal to the second input-output port and to receive a data signal from the second input-output port, and a repeater circuit coupled to the first and second transceivers and configured to pass through the synchronization signal, and to resynchronize the data signal to generate the resynchronized data signal.

Extendable synchronous low power telemetry system for distributed sensors

An unmanned underwater vehicle (UUV) is disclosed. The UUV includes a body and a propulsion system for propelling and orienting the UUV. The propulsion system has an inlet formed in the body that facilitates fluid being drawn into the UUV from outside the body. The propulsion system also has a duct in fluid communication with the inlet. The duct is adapted to direct the fluid along a flow path. The propulsion system further includes a pump operable with the duct to increase the velocity of the fluid. In addition, the propulsion system includes a nozzle in fluid communication with the duct to receive the fluid at the increased velocity. The nozzle is supported about a side of the body and adapted to moveably redirect fluid out of the UUV. The propulsion system provides multi-axis control of the UUV.
