Magnetomechanical Markers For Marking Stationary Assets

View page
US Patent:
20120068823, Mar 22, 2012
Filed:
Sep 22, 2010
Appl. No.:
12/888272
Inventors:
Ziyad H. Doany - Austin TX, US
Dean M. Dowdle - White Bear Lake MN, US
Michael E. Hamerly - Vadnais Heights MN, US
William C. Egbert - Minneapolis MN, US
International Classification:
G08B 5/22
US Classification:
340 81
Abstract:
An article, system and method related to a magnetomechanical marker used to mark stationary assets. Magnetomechanical markers can be arranged in clusters and associated with stationary assets, including assets buried underground. Markers can be associated with an asset by being attached to the asset, arranged in a particular spatial relationship with the asset, or in any other appropriate way. A portable locating device can be used to generate an alternating magnetic field to activate the magnetomechanical marker and thus locate the asset.

Flexible Magnetic Core Electronic Marker

US Patent:
20120325359, Dec 27, 2012
Filed:
Jun 27, 2011
Appl. No.:
13/169687
Inventors:
Ziyad H. Doany - Austin TX, US
Dean M. Dowdle - White Bear Lake MN, US
William C. Egbert - Minneapolis MN, US
Michael E. Hamerly - Vadnais Heights MN, US
International Classification:
F16L 55/00
G06K 19/067
H01F 7/06
US Classification:
138104, 296021, 235492
Abstract:
An electronic marker and method of making an electronic marker for marking obscured articles. The marker includes a core made of flexible, and sometimes high permeability magnetic material and a solenoid disposed around the core. A capacitor is electrically coupled with the solenoid, and the marker is tuned to respond to a signal at a characteristic resonant frequency. The marker can attached to a conduit to be buried underground. The marker can further include a radio frequency identification chip.

Variable Frequency Rf Electronic Surveillance System

View page
US Patent:
46099115, Sep 2, 1986
Filed:
Jul 19, 1985
Appl. No.:
6/756703
Inventors:
Gary E. Nourse - Osceola WI
Dean M. Dowdle - White Bear Lake MN
Assignee:
Minnesota Mining and Manufacturing Company - St. Paul MN
International Classification:
G08B 1324
US Classification:
340572
Abstract:
An electronic article surveillance system is disclosed, having a transmitter means for producing in an interrogation zone sequences containing a plurality of discrete different radio frequencies thereby causing a circuit present within the zone to resonate at its resonant frequency in response to energy absorbed at at least three different frequencies. A receiver means is provided to cause an alarm in the event of detection of three such resonances over two successive sequences.

Shielded, Closely Spaced Transmit-Receiver Antennas For Electronic Article Surveillance System

View page
US Patent:
45090394, Apr 2, 1985
Filed:
Jul 5, 1983
Appl. No.:
6/510780
Inventors:
Dean M. Dowdle - White Bear Lake MN
Assignee:
Minnesota Mining and Manufacturing Company - St. Paul MN
International Classification:
G08B 1324
H01Q 704
US Classification:
340572
Abstract:
A shielded, closely spaced transmit-receiver system for use in an electronic article surveillance system is disclosed wherein at least one of the antennas is provided with at least two twisted loops lying in a common plane each loop being twisted 180. degree. to be in phase opposition with the adjacent loop and wherein both antennas are substantially enclosed by a conductive shield having a discontinuity in an outer portion enclosing each of the twisted loops.

20150226872, Aug 13, 2015
Filed:
Apr 21, 2015
Appl. No.:
14/691654
Inventors:
- St. Paul MN, US
Dean M. Dowdle - White Bear Lake MN, US
Michael E. Hamerly - Vadnais Heights MN, US
William C. Egbert - Minneapolis MN, US
International Classification:
G01V 3/08

Single Turn Magnetic Drive Loop For Electronic Article Surveillance

View page
US Patent:
20150035716, Feb 5, 2015
Filed:
Aug 2, 2013
Appl. No.:
13/958252
Inventors:
- St. Paul MN, US
Dean M. Dowdle - White Bear Lake MN, US
Assignee:
3M Innovative Properties Company - St. Paul MN
International Classification:
G08B 13/24
H01Q 7/06
US Classification:
343788
Abstract:
A single turn loop electronic article surveillance (EAS) gate. The gate includes a closed magnetic core, a multi-turn primary winding wound around the core, and a secondary loop passing through the core once. The secondary loop is a self-supporting single turn loop, and the secondary loop is a transmit loop that generates a magnetic drive field for the article detection gate system.
