Detector
First Claim
1. A system, comprising:
- a loop configured to emit a magnetic field along a longitudinal axis of the loop, where the loop operates at a frequency of about 100 kilohertz or greater; and
a detection component configured to detect a presence of an object through an analysis of the magnetic field.

Abstract
Various embodiments are described that relate to a detector. The detector can include a loop functioning at a high frequency that emits a magnetic field. The magnetic field can be retrieved and a comparison can be made between the emitted magnetic field and the retrieved magnetic field. If there is substantially little difference between the emitted and retrieved field, then a determination can be that no object is present. Conversely, if there is a substantial difference between the emitted and retrieved field, then the determination can be that an object is present and thus the object is detected. If the object is present, the returned magnetic field can be further analyzed to determine the type of object that is detected.

15. A system, comprising:
-
a singular loop that operates at a frequency of about 1 megahertz or greater, where the singular loop is configured to emit a magnetic field along a longitudinal axis of the singular loop and where the singular loop functions concurrently as a transmission loop and as a reception loop; an identification component configured to identify a new location for a frequency notch associated with the frequency based on reception of the magnetic field, where the frequency notch moves from a base location to the new location and where a change of the location from the base location to the new location indicates a presence of an object; a classification component configured to determine a classification for the object based, at least in part, on the new location; and an output component configured to cause an output associated with the classification. - View Dependent Claims (16, 17)

18. A system, comprising
a loop, that operates at a frequency of about 100 kilohertz or greater to about 1 gigahertz or lower, configured to receive a magnetic field; -
an identification component configured to identify a new location for a frequency notch associated with the frequency based on reception of the magnetic field, where the frequency location moves from a base location to the new location and where the change of the location indicates an anomaly associated with the magnetic field; and an output component configured to cause an output associated with the anomaly. - View Dependent Claims (19, 20)
