摘要： PURPOSE:To enhance target searching capacity necessary for the navigation of a ship, by setting a high energy emitting azimuth and a low energy emitting azimuth, and increasing and decreasing the intensity of a pulse signal by the azimuth of the antenna detected to control electromagnetic wave energy. CONSTITUTION:An azimuth setting part 6 sets a high energy emitting azimuth alphaand a low energy emitting azimuth beta. An azimuth comparing part 8 judges whether the azimuth of the antenna 2 detected by an azimuth detection transmitter 4 is the azimuth alpha or the azimuth beta. The judge result is sent to an amplification control part 10 and the mu-factor of an RF pulse amplifier 9 is controlled so as to be increased and decreased on the basis of whether the azimuth of the antenna 2 is the azimuth alpha or the azimuth beta. When the antenna 2 is within the azimuth alpha being an important monitor azimuth, the level of a pulse modulation signal with definite frequency is enhanced and said signal is supplied to the antenna 2 to bring an emitted electromagnetic wave to high energy. By this method, target searching capacity necessary for the navigation of a ship is enhanced and reliability can be enhanced.

摘要： PURPOSE:To obtain a collision preventing device which has high reliability enough for automatic sailing by extracting and combining action elements from a memory stored with various action elements characteristic to a ship and setting a route satisfying an action reference at the time of sailing evasion. CONSTITUTION:A radar 5 tracks an object 35 when finding the object 35 on the course of its ship 34 and sends data on the motion (moving direction and moving speed) of the object 35 to a 1st computer 6. The 1st computer 6 selects a memory according to the probability obtained by computing the possibility of the collision of its ship 34 against the object 35 and sends a signal for the start of arithmetic to a 2nd computer 10. The 2nd computer 10 combines respective action elements aij taken out of some of memories 2-4 to generate many sailing evasion routes and evaluates those routes in terms of safety, economy, and laws and regulations according to the action reference read out of a memory 12. Then, a multistage action determining method is applied to the courses which meet requirements of the action reference, thereby selecting the best sailing evasion course.

摘要： PURPOSE:To prevent the illegal use of a computer system by using a means which collates the digital data to which the face video of a user is photographed with the registered face video of the user retrieved from the data base. CONSTITUTION:A user puts a collation card 10 through the card slit of a card reader 12 when the user uses a computer system 11. The collation code read by the reader 12 is outputted to a data base 13, a display 14 and a recorder 15 respectively. The data base 13 retrieves the digital data on the face video corresponding to the collation code. Then the retrieved digital data is given to an automatic video matching device 16. While the user's face is photographed by a digital camera 18 and given to the device 16 in the form of the digital data. The device 16 sets both digital data on each other to secure the best matching state of them. Then an automatic collation deciding device 19 decides the coincidence between both data.

摘要： PURPOSE:To perform an optimum target object image display by overlapping the images of an active noctovision camera for obtaining the scotopic image of a target object by the reflected waves of ultrainfrared pulses and a passive noctovision camera for obtaining the image of the target object by natural light each other. CONSTITUTION:Using an active noctovision camera 10 having infrared pulse generating means for generating the infrared pulses in infrared and ultrainfrared regions, the infrared pulses are directed to a target object and the scotopic image of the target object is obtained by the reflected waves of the infrared pulses, outputting the image as image signals. Further, the scotopic image of the target object by natural light is obtained by a highly sensitive passive noctovision camera 20 and outputted as image signals. After a contrast intensification, an image correction and the like are applied to the image signals of both the noctovision cameras 10 and 20 by a contrast intesifying circuit unit 31 to be clarified, both the images are displayed in an overlapped form.

摘要： PURPOSE:To increase a position measuring accuracy by catching and tracking a variable reflectivity radar reflector located on a buoy by a radar and calculating a ship's own position by means of the collation between the code of the reflector and set position data. CONSTITUTION:Received radar signals from a transmitter and receiver 20 and reflector response signals from a variable reflectivity radar reflector 60 are received by main and SLS antennas and pass through a video signal creator 208a or 208b to become received video signals. Both the signals are compared with each other in an SLS comparing circuit 210 and the received video signals produced by means of a side lobe are removed. Thereafter, radar video and reflector response video are separated by a multiplexer 211. In a processor 30, a reflector code and a reflector position are separated and extracted by a decoder 301. The extracted code is inputted to a computer 40, collated with the reflector code and position data and a ship's own position is calculated on bearing signals from a gyrocompass 70 and the like.

摘要： PURPOSE:To secure data transmission even if an optical transmission line is damaged by providing the titled network with an optical transmission line for connecting respective local stations(LSs) with a master station (MS) like a loop, individual radio communication means between respective LSs and the MS and a backup optical transmission line connected between the LS incapable of radio communicating and the MS. CONSTITUTION:The master station(MS) 12 is connected to respective local stations(LSs) 13-1-13-4 through optical fibers 14 consisting of two cores like a loop, respective LSs 13-2-13-4 are connected to respective radio transmitters 15-1-15-3 and the MS 12 is connected to radio receivers 18-1-18-2 corresponding to the radio transmitters 15-1-15-3. The LS 13-1 is arranged in an engine control room and a backup optical fiber 19 consisting of two cores is connected between the LS 13-1 and the MS so as to be used only when radio communication is disabled. The optical fiber 14a is usually used for data transmission between the LSs and the MS, and when the optical fiber 14a is damaged, data transmission is switched to the optical fiber 14a. When damages g1, g2 are generated on the fibers 14a, 14b for instance, a loop circuit is formed by the optical fibers 14a, 14b among the MS 12 and LSs 13-1, 13-3, 13-4, but the LS 13-2 is disabled to execute data transmission ased upon the optical fibers 14. At that time, the impossibility of data transmission is detected and the radio transmitter 15-1 is driven. When damages g3, g4 are generated on the optical fibers 14a, 14b on both the ends of the MS 12, connection between the MS 12 and the LS 13-1 is switched to the fiber 19 and radio transmitters 15-1-15-3 are driven.
