Title: Method and apparatus for controlling frequency deviation of a portable transceiver
Inventor: FREISEN KEVIN
IPC: H04B17/00
Filed: 1996-03-25
Abstract: A method and apparatus to control frequency deviation of a portable transceiver (PT) (122) utilizing a time-division-duplex (TDD) protocol for communicating with a base transceiver (116). The base transceiver (116) transmits (708) a first signal having first deviation levels (706). The PT  (122) receives (802) the first signal, measures (808, 810, 824) it to derive estimates of the first deviation levels, and stores (826) the estimates in a memory (322). The PT (122) generates (828) a second signal having second deviation levels (830) controlled by control signal values (323), samples (832) the second signal to derive a second received signal, and appraises (902) the second received signal to derive estimates of the second deviation levels (830). The PT (122) compares (906) corresponding estimates of the first and second frequency deviation levels (830) to derive adjusted control signal values (908) for controlling the second deviation levels (830) to approximate the first deviation levels (706), and thereafter controls (914) the second deviation levels (830) in accordance with the adjusted control signal values (908).
Patent CA-2220890-A1 (CA)
Inventor: CROSSMAN WILLIAM HERBERT
IPC: A01G9/24
Filed: 1998-01-20
Abstract: Natural gas pipelines typically employ an underground large diameter pipe, on the order of about 42 inches in diameter, to conduct natural gas from a gas field to a place of consumption or to a shipping terminal, Compressor stations disposed along the pipeline compress the gas to maintain an acceptable rate of flow along the line. Compressing process heats the gas in the pipeline, and the heat is gradually lost to the ground along the length of the line. The present invention discloses a system and method for the recovery of such waste heat from a pipeline in which one or more recovery tubes or coils disposed underground above or alongside the pipeline, carries a heat transfer fluid which collects the waste heat from the pipeline itself by radiant transfer mechanism. The system may include a manifold and pumping system to utilize the heated heat transfer liquid to heat greenhouses, fish ponds, houses, and other facilities.  The system may be employed to recover heat from any compressible fluid pipeline such as natural gas, propane, butane, etc. and may also be used in connection with liquid fluids such as oil or gasoline which also generate heat when passing through pipelines.

Abstract: An apparatus for displaying an all-around development image of a bored wall surface not only by a still image but also by a dynamic image by carrying out coordinate transformation at a high speed when the wall surface of a hole made by boring or a hole through which underground water flows is photographed and then developed into an all-around image. The digitalized image data are stored in each frame of an image memory by a memory data controller, and the data in odd-number fields and even-number fields of the image memory are read out alternately many times at a rate of 60 fields per second by a read memory address controller in accordance with vertical and horizontal synchronizing signals. During this time, the image data are read spirally by controlling a coordinate transformation table with reference to the directional data on the photographed image outputted from a direction indicator. The image data developed into a square diagram are converted into analog signals by a D/A  converter, and picture signals are outputted through a RGB matrix circuit.
