Sensor head
First Claim
1. An apparatus comprising:
- an extendable wand; and
a sensor head coupled to the wand by a hinged joint, the sensor head comprising a continuous wave metal detector (CWMD) and a radar, wherein the apparatus is configured to be collapsed into a storage configuration in which the wand is collapsed and folded over the sensor head at the hinged joint.

Abstract
An apparatus includes an extendable wand, and a sensor head coupled to the wand. The sensor head includes a continuous wave metal detector (CWMD) and a radar. When the wand is collapsed, the wand and the sensor head collapse to fill a volume that is smaller than a volume filled by the sensor head and the wand when the wand is extended. Frequency-domain data from a sensor configured to sense a region is accessed, the frequency-domain data is transformed to generate a time-domain representation of the region, a first model is determined based on the accessed frequency-domain data, a second model is determined based on the generated time-domain representation, the second model being associated with a particular region within the sensed region, and a background model that represents a background of the region is determined based on the first model and the second model.

14. An apparatus comprising:
-
an extendable wand having a first end and a second end, opposite the first end; a sensor head coupled to the wand at the first end by a first hinged joint, the sensor head comprising a continuous wave metal detector (CWMD) configured to radiate electromagnetic radiation and detect electromagnetic radiation, wherein the sensor head is configured to fold, at the first hinged joint, alongside the wand when in a storage configuration; and a housing coupled to the wand at the second end by a second hinged joint, the housing comprising a processor and an electronic storage coupled to the CWMD, the electronic storage comprising instructions that, when executed, cause the processor to access data detected by the CWMD and determine a signature of an object represented by the accessed data, wherein the housing is configured to fold, at the second hinged joint, alongside the wand when in the storage configuration. - View Dependent Claims (15, 16, 17)

18. An apparatus comprising:
-
an extendable wand having a first end and a second end, opposite the first end; a sensor head coupled to wand at the first end by a first hinged joint, the sensor head comprising a metal detector configured to radiate and detect radiation, wherein the sensor head is configured to fold, at the first hinged joint, alongside the wand when in a storage configuration; and a housing coupled to the wand at the second end by a second hinged joint, the housing comprising a processor and an electronic storage coupled to the metal detector, the electronic storage comprising instructions that, when executed, cause the processor to access data detected by the metal detector and determine that an object is represented by the accessed data, wherein the housing is configured to fold, at the second hinged joint, alongside the wand when in the storage configuration. - View Dependent Claims (20)
