20100277358 | Detection of surface and buried objects - A sensor head includes a ground penetrating radar (GPR) system and a continuous-wave metal detector (CWMD). The GPR system includes a transceiver configured to transmit radiation toward an object and to receive radiation from the object. The CWMD includes a transmission antenna configured to produce a first magnetic field in the vicinity of the object sufficient to generate a current in the object, and a receive antenna configured to sense a second magnetic field produced by the current generated in the object. | 11-04-2010 |
20110068795 | CONTINUOUS WAVE METAL DETECTOR - A training set including a target object set and a clutter object set is accessed. It is determined that the training set includes multiple types of targets or multiple types of clutter. The target feature value of a type of target is compared with the clutter feature value. The type of target is associated with the non-target object based on the comparison. A classifier is trained using the target feature value and the clutter feature value of the associated type of target and the non-clutter object. A feature value associated with an unknown object is applied to multiple classifiers to generate a set of metrics for the unknown object. The metrics are aggregated into an overall metric. Whether the unknown object is included in the target set is determined based on the overall metric. | 03-24-2011 |
20120254208 | SIGNATURE IDENTIFICATION AND DISTRIBUTION - A device includes a sensing element configured to produce a representation of an object in a space near the sensing element, an electronic storage comprising multiple representations, each representation being associated with a particular object, a communications interface, and a processor operable to receive the representation of the object in the space from the sensing element, compare the representation of the object in the space to the multiple representations stored in the electronic storage, determine that the representation of the object in the space is different from all of the multiple representations based on the comparison, identify the representation as a new representation based on the determination, and cause the new representation to be available to a data site through the communications interface. The device also may obtain a new representation from the data site. | 10-04-2012 |
