Title: Passive optical network system and its operation method
Inventor: MIZUTANI MASAHIKO
IPC: H04L12/44
Filed: 2008-03-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide a PON structure which saves power consumption and costs, and extends a transmission distance to accommodate more users, and its operation method.  <P>SOLUTION: In a passive optical network system, transmission distance or transmission time between OLT and ONU is measured during operation. If distance or time is short, high-speed communication is performed to increase user accommodation; and if transmission distance between OLT and ONU is long, low-speed communication is performed to secure a specified communication quality and then user accommodation is increased. To achieve this, a parent station has: a signal transmission/reception circuit for communicating with child stations at a first or a second transmission speed; and a controller which measures transmission distance or transmission time between the parent station and the child stations. Based on the measurement result, the controller selects a transmission speed for communication with the child stations.  <P>COPYRIGHT: (C)2010,JPO&INPIT

IPC: F41G7/30
Filed: 2008-04-10
Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem in a missile performing passive guidance wherein a guiding method using conventional technology may cause an ineffective guiding path along a main beam of a radar and make it impossible to secure a required guiding distance when terminal guidance becomes possible.  <P>SOLUTION: A command transmitting device 12 and a command receiving device 13 are added to a mother aircraft 2 and a missile 1, respectively, and positional information on the mother aircraft and a target 3 is transmitted by a radio circuit 14.
