Metal detector with data transfer
DCFirst Claim
1. A metal detector adapted to generate a transmit search signal and to receive a receive search signal, and to analyse such received search signal,wherein the detector is adapted to allow a selection of operating parameters for said receipt and analysis, said selection being effected by storage of data in a memory,characterised in that the detectoris adapted to allow such stored data to be modified to align with stored data in an external store, wherein the external store is a memory which is both outside of and spaced from the metal detector, and also from the memory within the metal detector which stores the data effecting the operating parameters;
- further comprising a digital data communication program, adapted to effect a transmission of some or all of the stored data through a data transmission link, thereby enabling a further metal detector to receive and store, for use in such further detector, said data,and wherein the operating parameters to be selected include a discrimination pattern, said discrimination pattern including at least one range of amplitude of a conductance component of a receive search signal and at least one range of amplitude of an inductive component of a receive search signal.

Abstract
A metal detector adapted to generate a transmit search signal and to receive a receive search signal, and to analyse such received search signal, wherein the detector is adapted to allow a selection of operating parameters for each of these functions, said selection being effected by the storage as data in a memory of such selection, characterised in that the detector is adapted to allow such stored data to be modified in accordance with data in an external store, further characterised in that there is a digital data communication transmission program, adapted to effect a transmission of some or all of the stored data through a data transmission means to enable a further metal detector to receive and store for use in such further detector the said data.

10. A method for operating ametal detector of a type which includes the ability to select values of operating parameters and to store such values as data, the method including the steps of:
-
a. receiving operating parameter data via an electronic transmission link from a data source external to the metal detector, the operating parameter data being a set of values of operating parameters, b. storing the operating parameter data in an electronic memory within the metal detector, and c. modifying the operating parameters of the metal detector to conform to the set of values of operating parameters specified by the operating parameter data, wherein the electronic transmission link includes a wireless connection transmitting through space between the metal detector and the external data source. - View Dependent Claims (11, 12, 13, 14, 15)

16. A set of two metal detectors of a type which includes the facility to select values of operating parameters and to store soch values as data, the set including
a. a first metal detector adapted to store data values in first electronic memory, the data values representing parameters used to determine a search strategy used by said first detector to maximize the likelihood of detection of a selected target, and to effect the transfer of said data values over an electronic data transmission link, and b. a second metal detector adapted to receive data values over the electronic data transmission link, and to store said data values into an second electronic memory, the second metal detector being further adapted to use said data values to effect a search strategy to maximize the likelihood of detection of the same selected target.
