Latest Patents

**Positioning Support Device and Positioning Support Method.** This invention improves approximate positional information used by a communication terminal. A server database associates approximate positional information with cell identifiers. When the terminal requests information for its cell, the server retrieves and transmits the corresponding data. It then uses positioning results received from the terminal to update the database, helping improve the accuracy of future positional estimates.

**Photoconductor for Electrophotography Comprising Squarylium.** This invention describes an electrophotographic photoconductor built on an electrically conductive substrate. Its layered structure includes a charge-generating layer containing a specified squarylium compound and a charge-transporting layer containing a hydrazone compound.
