Abstract: A lighting system has an elongate bracket having a recess for receiving an edge of a wall member in use such that the bracket extends along the edge of the wall member; a groove extending along the length of the bracket and spaced from the rear wall by an intermediate wall portion; and an electroluminescent wire extending along the length of the bracket at a position within the groove in front of the rear wall such that the electroluminescent wire is exposed in use.

Abstract: A system and method for communicating data between a downhole tool and a surface controller is provided that comprises a rotating drill string extending in a borehole and having a downhole telemetry module disposed proximate a bottom end thereof and transmitting a first signal across a telemetry channel. A surface telemetry module is disposed proximate a top end of the rotating drill string and is adapted to receive the first signal transmitted by the downhole telemetry module across the transmission channel. The surface telemetry module has a radio frequency transmitter disposed therein for transmitting a second signal related to the first signal. A stationary communication module has a radio frequency receiver adapted to receive the second signal.
