Appl. No.:

09/918619

Inventors:

Ming-Ren Lian - Boca Raton FL
Richard L. Copeland - Boynton Beach FL
Kevin Romer - Boca Raton FL

Assignee:

Sensormatic Electronics Corporation - Boca Raton FL

International Classification:

G08B 1314

US Classification:

3405721, 148100, 3405722, 3405728, 428611

Abstract:

The present invention replaces the conventional bias magnets for EAS markers with a paintable or printable bias magnet material, which is either directly painted onto the EAS marker or first placed onto a substrate material, which is then placed into the EAS marker. The material includes a magnetic powder mixed with resin and solvent. This âbias paintâ is then applied onto the EAS marker. The magnetic powder, resin, and solvent provide a very dense layer after drying, which has a magnetic material density that is usually lower than a rolled product, but is higher than that of the injection-molded magnet material. Printing the bias magnet allows nondeactivatable magnetomechanical EAS markers to be made using web-based mass production methods.

International Classification:

G11B 1500

US Classification:

360137, 324655, 3405725

Abstract:

An apparatus and method for determining the position of magnetic tape within a magnetic tape cassette to ascertain whether the magnetic tape is in a rewound position within the cassette is provided. In a first aspect of the present invention, the magnetic tape cassette has two internal magnetic tape take-up reels. The magnetic tape stored on the tape-up reels is detected. The rewound status of the tape is determined by whether the magnetic tape is detected on only one reel or on both reels. In a second aspect of the present invention, a preselected amount of magnetic tape is detected within the magnetic tape cassette. The magnetic tape cassette is oriented and the position of the detected magnetic tape is determined relative to the orientation of the magnetic tape cassette. In a third aspect of the present invention, an electronically detectable member positioned in a known location of the cassette is detected. A preselected amount of magnetic tape within the cassette is detected.

International Classification:

H01Q007/00

US Classification:

343866, 343742, 343867, 3405727

Abstract:

A phase compensated loop antenna having phase compensation elements distributed along the length thereof. The phase compensation elements compensate for current variations along the antenna length resulting from increasing the length of the antenna. A nested loop configuration incorporating at least one phase compensated loop antenna is also provided.

International Classification:

G08B 13/14

US Classification:

3405727, 343787

Abstract:

An EAS or RFID system including first and second core antenna systems. The first and second antenna systems establish magnetic fields having opposite directions and are positioned so that the fields at least partially cancel outside of an interrogation zone for detecting an EAS or RFID tag. There is also provided an EAS or RFID wherein the magnetic field direction established by a core antenna is varied at certain time intervals to minimize the effects of null zones in the interrogation zone.

US Classification:

3405721, 3405725, 3405727

Abstract:

An electronic article surveillance antenna system for wide exit interrogation zones is provided. In a first aspect, a first and a second transmit antenna, each adapted for installation on opposite sides of a wide interrogation zone. A third transmit antenna is adapted for installation adjacent the ceiling of the wide interrogation zone. The first, second, and third transmit antennas are connectable to a transmitter for generation of an interrogation signal for transmission into the wide interrogation zone. A plurality of amorphous core receiver antennas are adapted for installation in the grout region of a floor of the wide interrogation zone. The output of each of the plurality of amorphous core receiver antennas are connectable to a receiver for detection of a response signal from an electronic article surveillance tag disposed in the wide interrogation zone. The response signal is responsive to the interrogation signal. The plurality of amorphous core receiver antennas can be configured in a plurality of orthogonal pairs of amorphous core receiver antennas.

Abstract:

Techniques for tuning an antenna to different operating frequencies are described. An apparatus includes a security tag with a substrate having a surface, a lead frame to mount on the surface and connect to an antenna, and an integrated circuit to connect to the lead frame. The antenna may be disposed on the surface, and may comprise a first antenna portion and a second antenna portion. The first antenna portion may connect to the first side and the second antenna portion may connect to the second side. The antenna may be tuned to an operating frequency by modifying a first length for the first antenna portion and a second length for the second antenna portion after the antenna portions are disposed on the surface. Each portion has a first antenna end and a second antenna end, the first antenna end to connect to the lead frame, and the first antenna portion may form an inwardly spiral pattern from the integrated circuit in a first direction, and the second antenna portion may form an inwardly spiral pattern from the integrated circuit in a second direction. Other embodiments are described and claimed.
