Embedded systems (Life detecting circuit using PIC microwave controller) ABSTRACT: A new revolutionary microwave life detection system. Which is used to locate human beings buried (or) trapped under earthquake rubble has been designed. This system operating at certain frequency can remotely detect the breathing and heart beat signals of human beings buried under earthquake rubble. By proper processing of these signals‚ the status of the person under trap can

undersea communication cables were laid in the 1850s by the British and were used for telegraphy purposes. For several decades scientists struggled with formidable electrical problems. For instance‚ undersea cables of the 19th century did not allow for amplifiers in the cables‚ so high voltages were used to combat the electrical resistance across the cables. This problem severely limited the cable’s bandwidth to 10-12 telegraph words per minute (2). The technology required to effectively communicate across

telegraphone was able to perform other jobs such as office dictation and answering phoenes‚ a few European companies tried to market the product in the 1920s with enhanced features. These machines were able to pick up weak telephone signals and with amplifiers could reproduce the sound with better volume. Examples of these machines included the taxtaphone and the Dailygraph. In the early 1930s A german electrical manufacturer and his team designed a new kind of tape recorder‚ but instead of Poulsen’s
