Abstract: A power control method and apparatus are provided for a satellite based telecommunications system.  The system includes a power control subsystem which is operative with systems operations center for distributing available satellite power between earth stations.   Each earth station includes a baseband manager which subdivides the available satellite power between subband beams emitted from the satellite.   The earth station further includes beam processors which manage the power allocated to each subband within an associated beam in order to maintain a desired signal quality in a forward link between the satellite and user terminals within the associated subbands.  The beam processors communicate with modems,  each of which  is  assigned to a particular user terminal.  Each modem controls the satellites transmission power in the forward link to the user terminals to maintain a desired signal-to-noise ratio at the user terminal receiver.  The signal-to-noise ratio is determined by the corresponding beam processor.          The subsystem further provides a dynamic power control loop between user terminals in the forward and return links to maintain a desired signal quality.  The subsystem automatically controls the satellite output power level to ensure proper power emission by a satellite in connection with feeder links from multiple earth stations.

Granted: 2007-06-26
Abstract: A preferred novel breaker-crosslinker-polymer complex and a method for using the complex in a fracturing fluid to fracture a subterranean formation that surrounds a well bore by pumping the fluid to a desired location within the well bore under sufficient pressure to fracture the surrounding subterranean formation. The complex may be maintained in a substantially non--reactive state by maintaining specific conditions of pH and temperature, until a time at which the fluid is in place in the well bore and the desired fracture is completed. Once the fracture is completed, the specific conditions at which the complex is inactive are no longer maintained. When the conditions change sufficiently, the complex becomes active and the breaker begins to catalyze polymer degradation causing the fracturing fluid to become sufficiently fluid to be pumped from the subterranean formation to the well surface.

Abstract: A rear differential in a four-wheel drive vehicle includes a left and right clutches adapted to distribute a driving force transmitted from front wheels through a propeller shaft to left and right rear wheels. If the engagement of the left and right clutches is released, only the front wheels are driven and in this manner, the vehicle is brought into a front wheel-drive state. If the left and right clutches are brought into their engaged states, both of the front wheels and the rear wheels are driven and in this manner, the vehicle is brought into a four-wheel drive state. By changing the engagement forces of the left and right clutches, different driving forces can be distributed to the left and right rear wheels. In addition, when a driver operates a differential lock switch, the left and right clutches, are brought into their engaged states with the maximum engagement force, thereby integrally coupling the propeller shaft to the left and right rear wheels to provide a differential-locked state. Thus, a differential lock mechanism can be provided to the differential in a simple structure.

Abstract: A wireless communication system which is reconfigurable to accommodate varying traffic density is provided by using a flexible optical interface between a base station controller and several base stations. Communication between the base station controller and the base stations is provided over an optical fiber. The fiber carries several communication channels in both directions using wavelength multiplexing. The bandwidth between the base station controller and a particular base station is varied by increasing or decreasing the number of wavelengths used to communicate with the base station. Varying the bandwidth provides the ability to adjust the capacity to carry voice and/or data between the base station controller and the base station. As a result the number of radio frequency carrier frequencies assigned to a base station can be varied to support varying radio frequency traffic density throughout the wireless network.

Title: Agricultural feed bag unloading apparatus
Inventor: STRANKMAN DOUGLAS R
IPC: A01F25/20
Filed: 1999-03-22
Granted: 2004-06-22
Abstract: An apparatus for unloading compacted agricultural feed from an elongated storage bag of the type formed from sheet plastic material. The apparatus includes a wheeled framework having a front part for facing an open end of the bag and a transversely extending rotating cylindrical mounted on pivoting arms for fragmenting the feed exposed at the open end of the bag and transferring the feed rearwardly into a transverse trough which has a conveyor system for transporting the fragmented feed to an area of removal. A lower transverse roller has an outer surface for driving engagement with a lower portion of the sheet material forming the bag beneath the compacted contents of the bag and upon rotation of the roller developing a pull on the framework to thereby move the apparatus towards the open end of the bag. The winding up of the lower portion of the sheet material causes a raising of the sheet material from the ground to at least the level of a front edge of the trough to provide an upper surface over which the feed is delivered to the trough and further results in a storage of the continuous plastic material as it is removed from the bag.
