Emdros is a text database middleware-layer aimed at storage and
retrieval of "text plus information about that text." This
information could be linguistic analyses or other annotations. Emdros
provides an abstraction of text that makes it well suited to storing
/syntactic analyses/ of text, but other linguistic information is
supported as well. Emdros comes with a query-language, MQL, that
enables powerful queries. Emdros acts as a middleware-layer between a
client (not provided) and a database back-end. Currently, PostgreSQL,
MySQL, and SQLite (2 and 3) are supported, but other back-ends can
easily be added.

Wireless range extenders or wireless repeaters can extend the range of an existing wireless network. Range extenders can be strategically placed to elongate a signal area or allow for the signal area to reach around barriers such as those created in L-shaped corridors. Wireless devices connected through repeaters will suffer from an increased latency for each hop. Additionally, a wireless device connected to any of the repeaters in the chain will have a throughput that is limited by the weakest link between the two nodes in the chain from which the connection originates to where the connection ends
