Title: Reducing crosstalk between communications systems
Inventor: TERRY JOHN BRIAN
IPC: H04B3/46
Filed: 1997-01-15
Granted: 2002-04-02
Abstract: Modems (12, 14) using a telephone line (10) for high speed communications between them are arranged to monitor crosstalk (24, 26) from other existing communications systems (16, 18, 20, 22) with which they may mutually interfere, and adjust the power spectral densities (PSDs) of their transmitt ed signals to reduce overlap between the PSDs of the different systems, thereby  reducing near end crosstalk. Communications can thereby be optimized for whatever crosstalk conditions may exist. The modems can have a master-slave relationship for communicating buffered frames in a half-duplex manner using  a collision avoidance protocol for computer network access. Analysis of monitored crosstalk PSD information can be performed by each modem, by the master modem, or by a separate computer on the network. A digital signal processor used in each modem for receiving signals can be configured to be used at other times for the monitoring of crosstalk.

Filed: 1999-06-01
Granted: 2006-08-22
Abstract: A simplified method of history handling for the Viterbi decoding of convolutional codes is described herein. The state number, or one or more of the most-significant bits of the state number, is loaded into the corresponding state history. Each state number represents the sequence of data bits that, in convolutional encoding, would give rise to the corresponding state. The most recent data bit provides the least significant bit of the state number. This invention reduces the processing requirements associated with the handling of the history, and is especially useful for decoder implementations using general-purpose processors.

Title: Novel sulfur transfer reagents for oligonucleotide synthesis
Inventor: TANG JIN-YAN
IPC: C07D285/135
Filed: 1998-05-26
Granted: 2008-01-29
Abstract: In our research, two commercially available compounds, 3-amino-1,2,4-dithiazole-5-thione (1) and xanthane hydride (2), and their derivatives 3-6 are found to be potential sulfur-transfer reagents. The efficiency and optimization of these new sulfur-transfer reagents were investigated by solid-phase synthesis of dinucleotide and oligonucleotide phosphorothioates. The results show that both compounds (1) and (2) are highly efficiency sulfurizing reagents, and better than 99 %  sulfur transfer efficiency can be achieved at each step. In contrast to Beaucage reagent, these novel sulfur-transfer reagents are very stable in various solvents, and are available in bulk quantities at low cost.  Due to these advantages, compounds (1) and (2) can be considered alternatives to Beaucage reagent, especially in large-scale preparation of oligonucleotide phosphorothioates. Furthermore, compounds (1) and (2) were modified to enhance their solubility in acetonitrile. Three types of structure, as described as Formulae (I), (II) and (III), are considered as potential efficient sulfur-transfer reagents based on our results.

Abstract: A control system, particularly adaptable to multiple-pump operations in process units, is disclosed.  A measured variable, such as pressure, is sensed by a master controller.   The master controller, in turn, sends a signal to the driver of the individual pumps or in other ways regulates the output of the two pumps. The master controller is configured to send different signals simultaneously to the two pumps in response to a change in the measured variable. The result is that the response time of one of the pumps is faster than the other. Thus, minor deviations from the desired setpoint of the measured variable are primarily responded to by the pump configured to react faster. Dramatic upsets, resulting in a significant deviation from the desired setpoint for the measured variable, allow one pump to react fast and change its capacity dramatically to bring the measured variable back to the desired setpoint, while the other pump responds more slowly and thus maintains a reasonable forward fluid flowrate all the time to prevent a process unit shutdown. On sensing a loss of the fast-responding pump, the master controller automatically speeds up the response time of the slowly responding pump so that its capacity can be varied reasonably fast enough to maintain the measured variable at the target condition. By use of differing response times on the pumps, the tendency of the pumps to fight each other when operated by steam turbines, for example, is eliminated. Additionally, the pumps with the control system can quickly respond to large process upsets without triggering shutdown conditions of both pumps which would otherwise cause a processing unit shutdown.

Abstract: A transparent conductive laminate in which a crystalline transparent conductive film substantially made of In-Sn-O is formed on the transparent substrate composed of a thermoplastic polymer film. The crystalline part of the transparent conductive film (ITO film) is a transparent conductive laminate having a special crystal structure in which the strength of X-rays diffracted by the (222) crystal plane or the (440) crystal plane is the highest and the ratio [X440/222] of the strength of X-rays diffracted by the (440) crystal plane to that by the (222) crystal plane is within a range of 0.2 to 2.5. The transparent conductive laminate is low in surface resistivity and useful as an electrode material such as of a liquid crystal display, an electroluminescence device, or a touch panel. The transparent conductive laminate is manufactured by a combination of control of the film-forming atmosphere in sputtering and heat treatment under specific conditions after the film is formed.
