First Claim
Patent Images
1. A buried object detection system comprising:
- a sensor head having a sensor configured to detect electromagnetic signals;
a sensor head status sensor configured to generate status data related to the sensor head; and
one or more processors configured to detect a buried object based on the electromagnetic signals and to determine a position or a motion of the sensor head based on the status data, the position or motion of the sensor head resulting from movement of the detection system by an operator, wherein at least one of the one or more processors is configured to process the status data to determine whether the sensor head is being moved correctly by an operator of the buried object detection system.

Abstract
A hand-held, wand-type buried object detector includes a motion and position sensor that provides data about the sensor head of the buried object detector. An inertial measuring device including three accelerometers and three gyroscopes is one example of a motion and position sensor. The buried object detector includes a processor/communicator device that is capable of processing the data from the motion and position sensor and communicating feedback, based on the processing results, to the operator about the operation of the buried object detector. In one example, a personal digital assistant may be configured for use as a processor/communicator device of a buried object detector.
