  • Patent number: 5315517
    Abstract: A mobile machine having active sensors for allowing similar energy waves to coexist close to each other. A mobile machine enters an exclusive transmission mode with respect to energy wave transmission when interference can occur between its own active sensor and the sensors of mother mobile machines. Prior to the transmission of energy waves, the mobile machine determines whether or not any competing mobile machine has acquired the energy wave transmission right. If not, it broadcasts a declaration of its acquisition of the right to transmit energy waves and transmits energy waves. If the transmission right has already been acquired by a competing mobile machine, it adds its own identification to a transmission queue, and increments the transmission queue each time it receives a declaration of renunciation of the right to transmit energy waves from a competing mobile machine.

  • Patent number: 5307272
    Abstract: A multi-sensor system (10) for detecting the presence of objects on the surface of the ground or buried just under the surface, such as anti-personnel or anti-tank mines or the like. A remote sensor platform (12) has a plurality of metal detector sensors (22) and a plurality of short pulse radar sensors (24). The remote sensor platform (12) is remotely controlled from a processing and control unit (14) and signals from the remote sensor platform (12) are sent to the processing and control unit (14) where they are individually evaluated in separate data analysis subprocess steps (34, 36) to obtain a probability "score" for each of the pluralities of sensors (22, 24). These probability scores are combined in a fusion subprocess step (38) by comparing score sets to a probability table (130) which is derived based upon the historical incidence of object present conditions given that score set.
