    摘要： A system for remote detection of troop movement uses granular RFID tags that can respond with a signal when altered by that movement. The system includes a scanner, multiple granular-size radio-frequency identification tags, a conductor and a remote station. Each of the RFID tags includes a RFID chip that generates a responding signal to an interrogating signal from the scanner. Each RFID tag has an antenna so that the RFID tag can transmit the responding signal, but can do so only after the antenna is activated. A conductor is formed so as to short circuit the antenna and preclude the antenna from activating and transmitting the responding signal. The conductor breaks, and activates the antenna when the conductor is stepped on by a person walking on the RFID tag. The system includes a remote station configured to receive the responding signal retransmitted by the scanner.

    摘要： A back-up electrical safety device for a land mine is presented which proes an additional 50 to 60 second time delay concurrent with the conventional built-in one minute delay before any detonation is possible. A soldier is therefore afforded an additional assurance of an ear one minute time lag before an accidental explosion could be possible due to premature pulsing of the mines's built-in timer. A Darlington pair RC switching circuit appears electrically in tandem between the internal timer and the various arming means, to doubly insure an approximate one minute override before detonation. This dual safety feature permits hand-emplacement, over gun-launching, of a conventional land mine.

    摘要： A distance-measuring arrangement including transmission means for transmitting a wave in a measuring field, receiving means for receiving the wave reflected from a moving body moving in the measuring field and for producing a beat signal from the Doppler frequency. Delimiting means is provided for forming, in the measuring field, at least two datum lines (Ca and Cb) and processing means is provided for processing the distance information obtained from measuring the Doppler frequencies at the instants when the moving body crosses the datum lines. The delimiting means are formed from thermal detectors disposed in an optical assembly having at least two optical axes for defining the datum lines. A timing circuit is provided for defining the instants at which the moving body crosses the datum lines and for applying this information to the processing means.
