Michigan State University Extension Portal Planning and Implementation

ABSTRACT

Michigan State University Extension is launching a portal-based information system to help address information delivery, archiving, and cataloging, in addition to geographic dispersion and time and/or budget constraints. The system, expected for public launch during the first quarter of 2005, is described from the planning stages to current configuration. Library staff are cataloging and loading organizational content and helping to develop global content modules. Portal technology facilitates workgroup collaboration–a major design goal in addition to information management and delivery.

Analysis About the Coupling Circuit of the Communication With Low-voltage Power Line

In the interest of realizing carrier communication using LVPL, it is sticking point to analyse and design the coupling circuit of the communication. Higher efficiency of loading carrier signals is necessary. On the other hand, disturbs from LVPL should be overcome. Penman commendably resolved the difficult problem with the "complex-coupling-technology" of combining " electromagnetism - coupling" to "RC-coupling". Based on the " complex - coupling-technology" , "the interface circuit of the communication is analyzed and designed with LVPL. Simulation results and experimentation results show : the coupling circuit not only has higher efficiency of loading carrier signals but also can completely close off 50 Hz signal from LVPL. Therefore, the coupling circuit can apply to communication systems on LVPL.
