Patent FR-2679041-A1 (FR)
Inventor: GUY LE PARQUIER
IPC: G01S15/89
Filed: 1991-07-09
Abstract: An underwater object sensing system using sonar transmitting and receiving devices (20) on board a naval vessel (2) for monostatic operation forming receiving channels on reception, wherein the system, in order to allow bistatic operation, further comprises sonar transmitting devices (10) on board a self-contained unmanned underwater vehicle (1) moving ahead of and closer to the seabed than the so-called main naval vessel. Said transmitting devices (10) on the self-contained vehicle form directional channels to achieve the desired spatial resolution. These channels are encoded and the sonar receiving devices (21,22) on the main vessel are also designed for reception during bistatic operation, and are complemented by devices for separating the various transmitted codes which are received on a single receiving channel. The system may be used for mine detection and provides protection of the main vessel carrying the sonar receiving devices.

Title: Optical wideband network for telecommunication subscribers - has command and connector network communicating to subscriber units via optical links by interrogation and time division multiplexing
Inventor: PAUL VINEL
IPC: H04Q11/00
Filed: 1992-04-30
Abstract: The central unit (EX) has a command unit (CU) which controls a connector network (CN) and photonic switches (ETE0...ETE31).  The photonic switches connect the digital signals from the appropriate units through the optical distribution network (DN),  at different wavelengths (La,Lb).
