Abstract : The present invention relates to sonobuoys and more particularly to means for selecting and setting different operating parameters such as transmitter channel frequency, operating lifetime and depth of hydrophone deployment. A microcomputer and memory are provided within a sonobuoy and a single setting switch is provided to select data to be set in memory which retains the desired operating parameters. A second switch and display elements are provided which, after programming, can be used to provide a visual indication of the parameters which are in memory. After deployment of a sonobuoy and activation of a sea-water battery, the memory contents are transferred to operating circuitry to cause the sonobuoy to perform the programmed functions. It is therefore a general object of the present invention to provide an electronic function selector for programming a sonobuoy.
