 Police, fire, and other emergency organizations, as well as the military, have used two-way wireless radio communication since the 1930s. Early vehicle-based radios were large, heavy units. After the invention of the transistor in 1948, radios shrank in size to small handheld radio transceivers.
Public two-way radios with several frequency options are widely available as well. Usually limited in range to a few miles, these units are great aids for such mobile professionals as construction workers, film crews, event planners, and security personnel. |

 Fingerprinting, method of identification using the impression made by the minute ridge formations or patterns found on the fingertips. No two persons have exactly the same arrangement of ridge patterns, and the patterns of any one individual remain unchanged through life.
To obtain a set of fingerprint, the ends of the fingers are inked and then pressed or rolled one by one on some receiving surface. Fingerprints may be classified and filed on the basis of the ridge patterns, setting up an identification system that is almost infallible. |

 The first wireless communications devices were radio telegraphs. A telegraph is a device that sends simple electrical pulses along copper wires or through the air as radio waves. The pulses were caused by contact between two metal surfaces, and receivers interpreted these electrical pulses as tones or beeps. A code of long and short signals was developed to represent the letters of the alphabet, and in this way coded messages could be sent between telegraphs.
Radio telegraphs used radio waves rather than wire telegraph lines to send and receive messages. Radio telegraphs sent telegraph signals over long distances and were ideal for ship-to-shore communication. Bulky radio telegraphs were installed on ships as early as 1899 and were widely used by 1905. |
