Agency of signal communication.-The term "agency of signal communication" embraces the personnel and equip- ment necessary to operate message centers, signal intelli- gence, signal supply, signal repair, and messenger, pigeon, radio, visual, sound, and wire communication. c. Means of signal communication.-A "means of signal communication" is an agency of signal communication capable of transmitting messages. The following agencies are means of signal communication: messenger, pigeon, radio, visual, sound, and wire. d. Command post.-The command post is the location of the forward echelon of a headquarters during combat from which tactical control is normally exercised and to which tactical information from subordinate units is sent. When the commander leaves his command post for any purpose, 2 SIGNAL COMMUNICATION 5-8 he maintains constant communication with it through the speediest and most reliable means of signal communication available to him. Only by such means can his effectiveness as a tactical commander be constantly maintained. e. Axis of signal communication.-To secure continuity of command and signal communication in combat when the movement of command posts either forward or backward is contemplated, the probable successive command posts should be selected in advance. The "axis of signal com- munication" is designated by naming these probable suc- cessive locations in the direction of movement. These points may not actually be occupied by the command post, but the command post will move along the route indicated by the points named. * 6. SIGNAL AND COMMVUNICATION UNITS.-Specially trained personnel and technical equipment required for the operation of signal communication are provided by Tables of Organiza- tion and Tables of Basic Allowances for signal communica- tion units to serve each battalion and higher headquarters.

  • Null by Morse: Historical Optical Communication to Smartphones
    Null By Morse: Historical Optical Communication to Smartphones Tom Schofield Culture Lab Tom Schofield Newcastle University King’s Walk Newcastle upon Tyne NE1 7RU United Kingdom [email protected] ABT S RACT Null By Morse is an installation artwork that incorporates a military signaling lamp and smartphones. A series of Morse messages is transmitted automatically by the signal lamp. The messages are drawn from the history of Morse and telegraphy. A custom app for iPhone and Android uses the phone’s camera to identify the changing light levels of the lamp and the associated timings. The app then decodes the Morse and displays the message on the screen on top of the camera image. This paper discusses the artwork in relation to the following theoretical aspects: It contextualizes the position of smartphones in the history of optical communication. It proposes an approach to smartphones in media art that moves away from futurist perspectives whose fundamental approach is to seek to creatively exploit the latest features. Lastly, it discusses the interaction with the phone in the exhibition context in terms of slow technology. Introduction Null By Morse (NBM) is an installation artwork that explores optical communication on smartphones with a media archaeological approach. Media archaeology is a loose term employed to cover recent scholarship that seeks to re-examine the material history of technology to better, or at least differently, inform our evaluations of the present. Alternate histories of suppressed, neglected, and forgotten media that do not point teleologically to the present media-cultural condition as their “perfection.” Dead ends, losers, and inventions that never made it into a material product have important stories to tell [1].

Dhage Department of Computer Science and Engineering AGMRCET-Varur, Hubli, Karnataka, India Abstract- -This article presents a secure wireless communication using Morse algorithm explicitly the setup includes system connected with Relay/Optocoupler. Morse code algorithm is used to convert simple sentences to dash (“-“) and dots (”.”) .The setup includes bulb whose intensity varies based on input character. And webcam facing opposite side bulb. When the character is typed Morse code generator encodes it and decodes at opposite side. So as bulb blink, webcam detects it and through simple threshold based video processing and the interface translates the blinks back to sentences. The same arrangement is placed at the other side. Communication is possible only between authenticated users. This sort of communication can’t be decoded, no airtel or Google can store a copy of it so great for security. Keywords – Morse code encoding, decoding. I. INTRODUCTION Wireless communication is a transfer of information between two points that are not connected by electrical conductors. It allows a secure means of communication only between authenticated users.

  • A Robust Real-Time Automatic Recognition Prototype for Maritime Optical Morse-Based Communication Employing Modified Clustering Algorithm
    applied sciences Article A Robust Real-Time Automatic Recognition Prototype for Maritime Optical Morse-Based Communication Employing Modified Clustering Algorithm , Xiaozheng Wang y, Minglun Zhang * y, Hongyu Zhou, Xinglong Lin and Xiaomin Ren State Key Laboratory of Information Photonics and Optical Communications, Beijing University of Posts and Telecommunications, Beijing 100876, China; [email protected] (X.W.); [email protected] (H.Z.); [email protected] (X.L.); [email protected] (X.R.) * Correspondence: [email protected] These authors contributed equally. y Received: 31 December 2019; Accepted: 7 February 2020; Published: 12 February 2020 Abstract: In maritime communications, the ubiquitous Morse lamp on ships plays a significant role as one of the most common backups to radio or satellites just in case. Despite the advantages of its simplicity and efficiency, the requirement of trained operators proficient in Morse code and maintaining stable sending speed pose a key challenge to this traditional manual signaling manner. To overcome these problems, an automatic system is needed to provide a partial substitute for human effort. However, few works have focused on studying an automatic recognition scheme of maritime manually sent-like optical Morse signals. To this end, this paper makes the first attempt to design and implement a robust real-time automatic recognition prototype for onboard Morse lamps. A modified k-means clustering algorithm of machine learning is proposed to optimize the decision threshold and identify elements in Morse light signals. A systematic framework and detailed recognition algorithm procedure are presented. The feasibility of the proposed system is verified via experimental tests using a light-emitting diode (LED) array, self-designed receiver module, and microcontroller unit (MCU).
