Abstract
Abstract Apparatus for setting and/or monitoring the operation of an electronic fuse for shells to be fired from a gun, by transmitting a microwave data signal and a microwave energy signal to a device inside the fuse from a device outside the fuse, the device inside the fuse including an energy receiver with a rectifier for generating a supply voltage, a data receiver, a data processing unit and a fuse electronic system, and the device outside the fuse including an energy transmitter, an input/output unit and a data transmitter, including means for disposing the device outside the fuse so that the transmission of the microwave signals occurs at the latest during loading of the shell carrying the fuse into the gun; means for transmitting the energy signal and the data signal together and simultaneously; a reply signal transmitter additionally included in the device inside the fuse; a reply signal receiver additionally included in the device outside the fuse; the data-signal transmitting means and the reply signal transmitter being actuable for transmitting and exchanging information in opposite directions; and a respective single antenna located at the fuse and at the device outside the fuse for receiving and transmitting energy, data and reply signals.
