down-link telemetry

The downward opening path (X) of said sealing body is shorter than the downward path of the lifting element (52) with the sealing body (56).

Reversal of flow is prevented by a one-way valve (75) in the coupling (30) in the downstream path.

A descending path (25) extends from each said location and provides for the transfer of used material from the respective location successively through the chambers.

In the power control scheme of the present invention, the transmitter power controller estimates the signal strength and quality of the down-link signal by determining a threshold adjustment parameter for the received signal.

A base station is provided.

The compliant nature of such material, when put into service in a centralizer for tubulars to be expanded prevents scoring the pipe on the way downhole.

The method includes sequentially repeating transmitting the downlink signal, each repetition with a different weight vector from the sequence until all weight vectors in the sequence have been transmitted with.

A sloped member (35) at the base of the dispenser inclines forward into the downward path of the stack to contact at least a lowest one (33a) of the articles of the stack.

The receiver (202) of the subscriber terminal (20) compares a code and phase of a master code sequence in the downlink signal (212) to a code and phase of a slave code sequence of the receiver (202).

A mobile station comprises means (301, 302, 303, 304, 326) for receiving downlink data from test equipment and means (331, 310, 311, 312, 313) for sending uplink data to the test equipment.

Thus, a pilot pattern is formed in the downlink signal, and the pilot pattern is formed of a product of a cell-specific scrambling code and a cell group-specific code.
