Title: Optical fiber network system
Inventor: NAGABORI TAKESHI
IPC: H04B10/27
Filed: 1995-03-17
Abstract: PURPOSE: To increase the transmission capacity with high economical properties without increasing the package size in an optical fiber network system by connecting an array optical transmission/reception circuit in an office building to plural optical network units via a multi-fiber-single-fiber conversion cable. CONSTITUTION: The array fibers 5 of an array optical transmission/reception circuit 6 in an office building 1 are turned into the single-fiber optical cables 51 to 5N by a multi-fiber/single-fiber conversion cable 4. These cables 51 to 5N are connected to the corresponding optical network units 11 to 1N respectively. The electrical crosstalk that is caused between the channels of the circuit 6 is eliminated by the separation and filtering of a power supply, and the input impedance of an optical receiving circuit which amplifies an optical current can be reduced against the spatial connection caused between the channels of an array optical detector. In such a constitution of a passive optical network system, the transmission capacity is increased with high economical properties without increasing the package size.

IPC: H04N7/18
Filed: 1993-03-19
Abstract: PURPOSE:To improve the accuracy of recognizing a vehicle running in the opposite direction even when plural spots are in existence by recognizing it to be head lights of the vehicle running in the opposite direction when a couple of bright areas corresponding to a vehicle width in the horizontal direction are in existence and a bright area is in existence under the bright areas. CONSTITUTION:A vehicle running in the opposite direction has a couple of left and right head lights and the light emitted to a concerned vehicle is formed as a couple of bright areas at a predetermined interval corresponding to the vehicle width in the horizontal direction. Thus, when a couple of bright areas A whose centroid coordinates Y1,2 are equal to each other whose X coordinate interval X1, X2 corresponds to a standard head lamp interval are detected in an image 120, it is an object area of the head lights of the vehicle running in the opposite direction. Moreover, the head lights are placed usually at a low position and the light reflected in the driving road is emitted in front of the vehicle. Thus, when the bright areas A are in existence in the image 120 and a bright area 3 is in existence under the areas A, the areas A are recognized to be head lights of the vehicle running in the opposite direction and the presence of the vehicle running in the opposite direction is recognized. Thus, even when plural light spots are in existence, the vehicle running in the opposite direction is recognized with high accuracy.
