Patent ID: 7885768

Claim:
A method implemented by a computer programmed to move a mobile sensor to locate a source of particles, molecules, or fragments of molecules in a search space, the mobile sensor being adapted to detect the presence of such particle, molecule, or fragment of particle, the method comprising: determining the particle, molecule, or fragment of molecule diffusion parameters in said search space; designing a lattice on said search space; determining if at least one particle, molecule, or fragment of molecule is detected by said sensor; computing, by a processor of the computer, a probability for each node of said search space lattice to be the source of said particles, molecules, or fragments of molecules according to the determined particle, molecule, or fragment of molecule diffusion parameters and to the detected particles, molecules, or fragments of molecules; evaluating a movement of said sensor according to said computed probabilities to locate a source of particles, molecules, or fragments of molecules in a search space; and moving said sensor according to the evaluated movement.
