Patent number: 10082572Abstract: 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.Type: GrantFiled: August 31, 2017Date of Patent: September 25, 2018Assignee: L-3 Communications Security and Detection Systems, Inc.Inventors: Herbert Duvoisin, III, Juan Antonio Torres-Rosario, Christopher Gary Sentelle, Douglas O. Carlson, Glen A. Holman, Marquette Trishaun

Publication number: 20130113648Abstract: Detection systems for scanning regions are disclosed. The detection systems may be used to detect various objects that are, for example, buried in the ground or obscured by being hidden on the body of a person. The detection systems include a sensor head having a continuous wave metal detector (CWMD) coil, radar antennas, and a transceiver electrically connected to a radar. The radar includes a transmit antenna configured to transmit electromagnetic radiation, and a receive antenna configured to sense electromagnetic radiation.Type: ApplicationFiled: August 24, 2012Publication date: May 9, 2013Applicant: L-3 COMMUNICATIONS CYTERRA CORPORATIONInventors: Herbert Duvoisin, III, Douglas O.

Patent number: 7532127Abstract: 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.Type: GrantFiled: October 20, 2005Date of Patent: May 12, 2009Assignee: L-3 Communications CyTerra CorporationInventors: Glen A.

Publication number: 20050227535Abstract: A cable sealing device (10) includes a member (14) comprising an elastomeric material and adapted to be fitted into a cable receiving aperture. The member includes a first wall (16) and a second wall (18) spaced apart from the first wall to partially define a cavity (20) between the walls. Each wall includes a cable receiving slot (e.g., 22, 24) formed in the wall. Each wall is deformable away from the respective slot to accommodate a respective cable portion (e.g., 26, 28) extended through the slot so that the wall is biased around the cable portion to minimize any opening around the cable portion passing through the slot. The slots in the respective walls cooperate to provide a redundant seal around a cable portion (30) passing through the member.Type: ApplicationFiled: February 8, 2005Publication date: October 13, 2005Inventors: Glen Holman, Andrew Filtness, Thomas Singer
