BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to theft deterrent security tags in general, and in particular to Electronic Article Surveillance (EAS) security tags that are coupled with articles without altering or damaging the article.
2. Description of Related Art
It is a common practice for retail stores to tag articles to prevent theft of the article by shoplifters. There are several methods of tagging articles, most common of which are coupling an EAS tag or markers (e.g., EAS labels) using adhesive, pins, lanyards or straps to trigger the EAS security system resulting in an alarm. The label markers are easy to remove while the cables or strapped tags are sometimes bulky or obtrusive to the person handling the article, making product placement of the article inconvenient and marketing thereof ineffective. As to pin type EAS tags, they are coupled with an article by the pin of the EAS tag puncturing the article, which may not be possible with most articles, such as skateboards, snowboards, pricey framed art, etc.
Accordingly, there remains a long standing and continuing need for an advance in the art of EAS and theft deterrent tags that makes the tags more difficult to defeat, simpler in both design and use, more economical and efficient in their construction and use, and provide a more secure and reliable engagement of the article to be monitored without damaging or altering the article.

The present invention provides an Electronic Article Surveillance (EAS) theft deterrent tag that is more difficult to defeat, simpler in both design and use, more economical and efficient in construction and use, and provides a more secure and reliable engagement of the article to be monitored without damaging or altering the article. FIGS. 1A to 1D are non-limiting, exemplary illustrations of the EAS theft-deterrent tag 100 coupled with an article in accordance with the present invention. As illustrated in FIGS. 1A to 1D, the present invention provides an EAS theft deterrent tag 100 (hereinafter referred to as “EAS tag 100”) comprised of a first (or main) member 104 that can be coupled with a first article portion of an article 102 and a second member 106 that can be coupled with a second article portion of the article 102, with the first (or main) member 104 associated with the second member 106 by an adjustable piece 108. The first (or main) member 104, the second member 106, and the adjustable piece 108 are separate and independent, forming separate and independent elements of the EAS tag 100 of the present invention. It should be noted that the EAS tag 100 may optionally comprise of only the first (or main) member 104 that may be coupled with the article 102 and the adjustable piece 108 that may be looped (or lassoed) around the article 102 and manipulated for a tight engagement of the main member 104 with the article. Accordingly, the second member 106 is optional.
The EAS tag 100 may be coupled with any type of an article 102 without damaging (e.g., puncturing) or altering the article 102, non-limiting examples of which may include the illustrated skateboard, a snowboard, frames or a framed artwork, flat-screen displays, laptop computers, etc. FIGS. 1E and 1F are non-limiting exemplary illustrations of the EAS tag 100 of FIGS. 1A to 1D in an uncoupled position in accordance with the present invention. As illustrated in FIGS. 1E and 1F, the main member 104 of the EAS tag 100 defines a main gap 110 for securing a portion of the article 102 therein, while the adjustable piece 108 is looped and wrapped around the article 102. More particularly, the first member 104 defines the first gap 110 for securing the first article portion therein, and the second member 106 defines a second gap 112 for securing the second article portion therein, with the adjustable piece 108 manipulated by a reel mechanism handle 114 for a tight engagement of the first and second members 104 and 106 with the article 102. The main member 104 accommodates an alarm switch 118 (also illustrated in FIG. 2B) that actuates upon securing the article 102 within the main gap 110, with the alarm switch 118 actuated when a side of the article 102 is pressed against the alarm switch 118 and the EAS tag 100 is tightly secured on the article 102 by the contraction (reeling-in) of the adjustable piece 108 by the reel mechanism (detailed below). After a tight mounting of the EAS tag 100 as illustrated in FIGS. 1A to 1D, the article 102 is protected by the EAS tag 100 upon actuation of a power switch 202 (FIG. 2A), which supplies power to an internal alarm system of the EAS tag 100 to arm the EAS tag 100. Accordingly, the first and second members 104 and 106 may be maneuvered to diagonally opposite directions when the adjustable piece 108 is extended, with the first and second members 104 and 106 maneuvered towards each other when the adjustable piece 108 is contracted to tightly couple the EAS tag 100 with the article 102.
FIGS. 2A and 2B are exemplary illustrations of the EAS tag 100 of FIGS. 1A to 1F, but without the illustrative article in accordance with the present invention. As illustrated, the first or main member 104 of the EAS tag 100 of the present invention includes the first gap 110 that is defined by a main first part 204 that contacts a first article side of the first article portion, a main second part 206 that contacts a second article side of the first article portion, and a main third part 208 that connects the main first and the main second parts 204 and 206 together, and contacts a third article side of the first article portion. The main first, second, and third parts 204, 206, and 208 defining the first gap 110 form the first or main member 104. It should be noted that the main first, second, and third parts 204, 206, and 208 of the main member 104 may be movably adjustable in relation to one another for varying a size of the main gap 110 by hinge mechanisms or the like.
The main first part 204 of the main member 104 accommodates a reel mechanism (detailed below), including the reel handle 114 that when in the open position (FIG. 2B), the reel handle 114 may be used to rotate and turn the internally located reel mechanism inside the main first part 204 to extend or reel-in the adjustable piece 208. The reel handle 114 moves to the open position (FIG. 2B) along the indicated reciprocating path 116 by a hinge mechanism 230, and may be pivoted along the reciprocating path 222 to reel-in or extend the adjustable piece 108 to a desired length, and flipped back to a closed position (FIG. 2A) along the indicated path 116.
The main second part 206 of the main member 104 accommodates a power source and electronics of an Electronics Article Surveillance (EAS) system, with the main third part 208 of the main member 104 accommodating the alarm switch 118 that actuates upon securing the article 102 within the main gap 110. As stated above, the alarm switch 118 is actuated when a side of the article 102 is pressed against the alarm switch 118, and the EAS tag 100 is tightly secured on the article 102. The main member 104 further accommodates the power switch 202 that is normally biased to extend out of a lateral rear side of the main third part 208 of the first member 104 when in open (or OFF) position, with the power switch 202 enabling supply of power to the internal alarm system of the EAS tag 100. The rear of the main third part 208 of the main member 104 includes a clutch housing 210 that accommodates a clutch (details of which are provided below).
As further illustrated in FIGS. 2A and 2B, the optional second member 106 of the EAS tag 100 of the present invention includes the second gap 112 that is defined by a first part 212 that contacts a first article side of the second article portion, a second part 214 that contacts a second article side of the second article portion, and a third part 216 that connects the first and the second parts 212 and 214 together, and contacts a third article side of the second article portion. The first, second, and third parts 212, 214, and 216 defining the second gap 112 form the second member 106, which accommodates to guide the adjustable piece 108 looped back towards the first member 104. It should be noted that the first, second, and third parts 212, 214, and 216 of the second member 106 may be movably adjustable in relation to one another for varying a size of the main gap 112 by hinge mechanisms or the like.
As further illustrated in FIGS. 2A and 2B, optionally, the gaps 110 and 112 may further include respective friction pads 220 and 218 that are coupled with the surfaces of the respective first, second, and third parts of the respective first member 104 and second member 106 that define the respective gaps 110 and 112. Accordingly, when tightly coupled with the article 102, the friction pads 220 and 218 of the EAS tag 100 will prevent the EAS tag 100 from sliding on a potentially smooth surface of an article 102, and will also prevent potential damage to article 102 (e.g., scratching the surface). More importantly, the friction pads 220 and 218 tightly grip the surface of the article 102, preventing the EAS tag 100 from being forcibly and intentionally maneuvered out and away from the article 102, thereby defeating the EAS tag 100. However, it should be noted that if the EAS tag 100 is somehow maneuvered out of position, the alarm switch 118 in contact with the article 102 would be actuated, triggering an alarm.

The inner conductors are longitudinally insulated from one another and from the outer conductors by inner dielectric layers, with an outermost outer conductor of outer conductors longitudinally insulated by an outer dielectric layer. A first distal end 344 of the cable is comprised of short-circuited first end of the inner and outer conductors, and a second distal end 346 of the cable is comprised of second ends 350 and 352 of the inner and outer conductors connected to respective ground (GND) and High of an electronic circuit housed inside the main second part 206 of the main member 104, forming the sense loop cable. The shorted-circuited first end 344 of the inner and outer conductors comprises electrical and mechanically connection of a first end of the inner and outer conductors, and the second ends 350 and 352 of the inner and outer conductors comprises electrical and mechanically connection with a Printed Circuit Board (PCB) of the electronic circuit housed inside the main second part 206 of the main member 104. As illustrated, the first distal end 344 includes a locking plug that encapsulates the short-circuited first end of the one or more inner and outer conductors.
As detailed in FIG. 4, the adjustable piece 108 is comprised of one or more insulated inner conductors 404 enclosed within and inside one or more insulated outer conductors 408, with a cross-section thereof illustrated and referenced as element 471 in FIG. 4. The inner conductors 404 are longitudinally insulated from one another and from the insulated outer conductors 408 by one or more inner dielectric layers 440. A transparent outer dielectric layer further longitudinally insulates the outermost outer conductor. In other words, all conductors are independently insulated from one another, with the exception of their first and second ends. The first distal end of the adjustable piece 108 (within the encapsulated locking plug 344) is comprised of short-circuited first ends of the inner and outer conductors 404 and 408, with the locking plug 344 encapsulating the short-circuited first ends. That is, the first end of the inner conductors 404 are mechanically and electrically connected (“pinched” together) with the first end of the outer conductors 408, forming a short-circuited return wire (referenced as 473 in FIG. 4), and encapsulated within the locking plug 344.
The second distal end 346 of the adjustable piece 108 is comprised of second ends 350 and 352 of the inner and outer conductors 404 and 408, which are coupled to printed circuit board, resulting in a sense loop cable. As further illustrated, the second distal end 346 further includes a conductive connector 348 that secures the inner and outer conductors 404 and 408, and securely maintains an extension 406 of the outer conductors 408. The inner and outer conductors 404 and 408 (and extension 406) are coupled with ground GND and an input of a microprocessor (detailed below). Also illustrated is an insulating layer 440 for the inner conductor 404. As illustrated, at least one of the conductors (in this exemplary instance the outer conductors 408) is an internal spirally-wrapped electrical conductive cord that is bulky and strong for added mechanical strength to secure an article 102. Accordingly, the extension 406 (electrically and mechanical connected with the bulky outer conductor 408 via the conductive connector 348) is used as the extension of the conductor 408 so to fit inside the first member 104 of the EAS tag 100, and allow outer conductor 408 to mechanically and electrically connected with the electronics of the EAS tag 100 via the less bulky extension 406.
FIGS. 5A to 5C are non-limiting exemplary illustrations of the various views of a coupling of the adjustable piece with the first member of the EAS tag (with the second member and most other elements stripped and removed for clarity) in accordance with the present invention. As illustrated in FIGS. 3A, 3B, and 5A to 5C, the first end 345 and the second end 346 of the adjustable piece 108 are coupled with the respective main first and second parts 204 and 206 of the first member 104, and the body of the adjustable piece 108 looping through the second member 106. As more specifically illustrated in FIGS. 5A to 5C, the first end 345 of the adjustable piece 108 is coupled with reel mechanism 322, and the second end 346 is coupled with the electronics housed in the main second part 206 of the main member 104. As stated above, the first end 345 of the adjustable piece 108 includes the encapsulation 344 that is inserted through a reel aperture 512, an internal reel guide channel 516, and permanently accommodated inside a housing 518 within the reel mechanism 322. The second end 346 is coupled with the electronics located inside the main second part 206 of the first member 104 and more specifically, with one end 350 or 352 of the multi-wire adjustable piece 108 coupled with ground and the other 352 or 350 coupled with the microprocessor. Accordingly, when the handle 114 is flipped to an open position along the path 116 and rotated along path 222, the reel mechanism 322 pivots and the adjustable piece 108 is either contracted or extended (depending on the direction of rotation of the reel), which enables the adjustable piece 108 to wound onto the reel 322 for contraction or wound off the reel for extension. As a result, the first and second members 104 and 106 may be maneuvered to opposite directions when the adjustable piece 108 is extended (wounds off the reel), and the first and second members 104 and 106 are maneuvered towards each other when the adjustable piece 108 is contracted (wounds onto the reel).
As further illustrated (in FIG. 3C in addition to FIGS. 5A to 5C), the reel mechanism 322 is accommodated within a through-hole, transverse the longitudinal axis of the main first part 204 of the first member 104. The reel mechanism 322 is comprised of a revolving spool 504 with the handle 114. The handle 114 is coupled with the spool 504 via a pair of fasteners 530 that are inserted through a pair of posts 520 that form the connection point of the handle 114 with the spool 504. The spool 504 is comprised of a first flange 506, a second flange 510, and a spool body 502, with the first flange 506 having a wider span than the second flange 510. The first flange 506 has a periphery that includes a wall that is serrated 508 along an exterior facing side. The spool body 502 in between the first and second flange 506 and 510 accommodates a majority portion of the adjusting piece 108 when contracted, and includes the opening 512 for insertion and interlocking of a first end 345 of the adjustable piece 108 at a substantial center of the spool body 502.
Referring back to FIG. 3C, as illustrated, the main first part 204 of the first member 104 accommodates (amongst others) a power switch 202, the details of which are illustrated in FIGS. 6A to 6C. Accordingly, FIGS. 6A to 6C detail the various views of a power switch used with the EAS tag of FIGS. 1A to 5C in accordance with the present invention. As illustrated in FIGS. 6A to 6C, the power switch 202 is moved along a reciprocating path 654, transverse a longitudinal axis of the first member 104 to actuate a power plunger switch 324 to enable supply of power to an internal alarm system of the EAS tag 100. In general, the power switch 202 is biased, extending out of a lateral rear side of the main first part 204 of the first member 104 when in open (power OFF) position by a biasing mechanism 650, includes clutch interlock aperture 626 for detachably interlocking with a clutch 644 when in closed position (power ON), and a beveled side 622 that progressively engages with an intermediate member 602 for actuating the intermediate member 602 along a reciprocating path 656 that is transverse the reciprocating path 654 of the power switch 202 to thereby release a plunger 628 of the power plunger switch 324 when the power switch 202 reaches a closed position (power ON). Accordingly, the power switch 202 is an asymmetrical element comprised of a first 620 that extends out of the lateral rear side of the main first part 204 to allow users to press the power switch 202 and move it against the bias of the resilient member 650 (e.g., spring 650) to commence supply of power to the electronics of the EAS tag 100 and turn it to ON. The opposite side of the first side 620 of the power switch 202 has a flat portion 632 and a beveled portion 622, with the beveled portion engaging the beveled section 630 of the intermediate member 602. The rear side 624 of the power switch 202 including the clutch interlock aperture 626 for detachably interlocking with a clutch 644 against the bias of the resilient member 650 when in closed position (power ON).
As further illustrated in FIGS. 6A to 6C, the clutch housing 210 accommodates the clutch 644 and a clutch biasing mechanism 642. The clutch biasing mechanism 642 is biased to move the clutch 644 in the direction indicated by the reciprocating path 652, allowing the engaging tip 646 to be moved and pushed inward extending and snapping into the clutch interlock aperture 626, and interlock with the interlock housing 648 of the power switch 202. The engagement of the engaging tip 646 with the interlock housing 648 interlocks with and maintains the power switch 202 in the ON position, against the bias of the biasing mechanism 650. The overall interlocking scheme of the clutch 644 with the power switch 202 as a result of their respective biasing mechanisms provides a mechanical biasing scheme that generates a holding strength that is increased under tensile and compression forces that attempt to separate the components when both are interlocked with one another.
As further illustrated in FIGS. 6A to 6C, when in the closed position (power ON), the beveled side 622 of the power switch 202 progressively engages with the intermediate member 602 for actuating the intermediate member 602 along a reciprocating path 656 that is transverse the reciprocating path 654 of the power switch 202 to thereby release a plunger 628 of the power plunger switch 324 when the power switch 202 reaches a closed position (power ON).
The intermediate member 602 includes a blade-like section 540 that has a beveled end 630 that engages with the beveled side 622 of the power switch 202 to actuate the intermediate member body 604 along the path 656 to engage or disengage a lateral flange 606 with the plunger 628 of the power plunger switch 324 to turn ON or OFF supply of power to the electronic components of the EAS tag 100. As illustrated, the lateral flange 606 extends substantially perpendicular an axial length of the intermediate member body 604 and has flange surface that can engage with the plunger 628.
As further illustrated, the intermediate member 602 accommodates an interlocking member 610 and biasing mechanism 608 within the intermediate member body 604. The biasing mechanism 608 urges the interlocking member 610 along the path 656 towards the spool 504 of the reel mechanism 322. The interlocking member 610 includes beveled serrations 612 at a first end thereof, which are oriented at a first direction that interlock with beveled serrations 508 of the spool 504 of the reel mechanism 322 that are oriented at a second, opposite direction. The spool 504, and the interlock member 610 and biasing mechanism 608 form a ratchet and pawl mechanism, wherein the ratchet wheel may be construed as the spool 504 and the pawl as the interlocking member 610, with the beveled serrations 612 of the pawl forming a first set of sloped teeth, and the beveled serrations 508 of the spool 504 forming a second set of oppositely oriented sloped teeth. When the spool teeth 508 are moving in a first direction, the pawl teeth 612 slide up and over a gently sloped edges of the spool teeth 508, with biasing mechanism 608 in a form of a spring forcing the pawl teeth 612 into the depression between the spool teeth 508 as the pawl teeth 612 pass the tip of each spool tooth 508. When the spool teeth 508 move in a second, opposite direction, the pawl teeth 612 catch against steeply sloped edge of a first tooth of the spool teeth 508 that the pawl teeth 612 encounter, thereby locking the spool 504 against the pawl tooth and preventing any further motion of the spool 504 in the second direction. Accordingly, when fully mounted onto an article 102, the EAS tag 100 may be tightened, but cannot be loosened unless done so by an authorized person.
A magnetic detacher may be used to release and pull back the clutch 644 from its biased position, and out and away from the switch 202 to release the power switch 202 to an OFF position. To disengage the clutch from the switch 202, the engaging tip 646 is retracted, released, and disengaged from the interlocked and engaged position within the interlock housing 648 (and out and away from the clutch interlock aperture 626 of the power switch 202) when the force exerted by the resilient member 642 is removed. The engaging tip 646 is released, retracted and disengaged from the interlock aperture 626 when the force exerted by the resilient member 642 is reversed, with the reversed force pulling the engaging tip 646 out and away from the interlock aperture 626, against the biasing mechanism 642. That is, to release an article, deactivate, and reset the alarm to OFF, the clutch housing 210 is brought into physical contact with well-known suitable (in terms of magnetic strength, for example) magnetic detacher that enables the release and removal of the engraining tip 646 from the switch 202, and the overall powering OFF of the EAS alarm tag 100. The magnetic detacher magnetically pulls-in the clutch 644 in the reciprocating path 652 against the push of the biasing mechanism 642 (compresses the illustrated spring 642) to thereby pull-out the engaging tip 646 away from the switch 202.
The disengagement of the clutch 644 from the switch 202, releases the force exerted on the biasing mechanism 650, which pushes the switch 202 back to its Off position along path 654. The release of the switch 202 to its OFF position reverses the actuation of the intermediate member 602, compelling flange 606 to contact and close plunger 628 to shut-OFF power to the internal alarm system. Further, the reversal of the actuation of intermediate member 602 also disengages the beveled serrations 612 of the intermediate member 610 from the beveled serrations 508 of the spool 504, enabling the reel mechanism 322 to rotate to extend the adjustable piece 108 and release the article.
Referring back to FIG. 3C, as illustrated, the main third part 208 of the first member 104 accommodates (amongst others) an alarm switch 118, the details of which are illustrated in FIGS. 7A to 7E. Accordingly, FIGS. 7A to 7E are non-limiting exemplary illustrations that detail the various views of an alarm switch used with the EAS tag of FIGS. 1A to 6C in accordance with the present invention. As illustrated in FIGS. 7A to 7E, the alarm switch 118 is comprised of a substantially T (or “hammer” like) configuration that includes a handle section 640 and a head section. A lower end of the handle section 640 is comprised of a pivot arm 718 that ends in a pivot aperture 720 that accommodates a pivot shaft 330, enabling the alarm switch 118 to pivot along a reciprocating path substantially parallel the longitudinal axis of the first member 104 to one of actuated and non-actuated positions. The upper end of the handle section 640 is coupled with the head section, which includes an engaging portion 712 that contacts with the article. The head section further includes a first lateral beveled engaging portion 706 that closes an alarm plunger switch 306 when the alarm switch 118 is actuated, and a second lateral flat section 708. Further associated with the alarm switch 118 is a biasing surface 332 that is coupled with the handle section 640 and maintains the alarm switch 118 to a non-actuated position by a contacting biasing mechanism 717. Once the biasing surface 332 is pushed (as a result of an article 102 pushing against the alarm switch 118), the beveled edge 706 slides and pushes the plunger 702 of the alarm plunger switch 326 to set the internal alarm. The contacting biasing mechanism 717 is comprised of a first end 716 that contacts the biasing surface 332, a resilient section 334 that is mounted onto the pivot shaft 330, and a second end 714 that contacts the base-board 740 of the alarm tag to maintain the alarm switch 118 to an OFF position.
FIG. 8A is an exemplary illustration of the circuit schematics illustrating the circuit topography of the alarm system in accordance with the present invention. As illustrated, the EAS tag 100 includes a plurality of independent mechanical and electrical circuitry that function to protect the article 102 with which the EAS tag 100 is coupled for protection. A first module in an exemplary form of a power switch 202 has associated with it a first independent mechanical and electrical circuitry that powers the EAS tag 100. A second module in the form of the exemplary adjustable piece 108 (best illustrated in FIGS. 8B and 8C) has associated with it a second independent mechanical and electrical circuitry that enables a trigger of an alarm in case of tampering. A third module in the form of the exemplary arming mechanism 118 has associated with it a third independent mechanical and electrical circuitry that sets (or arms) the alarm tag and triggers an alarm in case of tampering. Finally, a fourth module in the exemplary form of one or more transponders 502a, 502b, . . . 502N that are associated with a fourth independent mechanical and electrical circuitry that receive or send signals, and trigger an internal and external alarms in case of an unauthorized removal of an article from a secure surveillance zone.
As illustrated in FIG. 8A, power is supplied to the power connector CON2 via a power source such as the illustrated battery 310, and switched ON by the switch S1, providing the power VCC to the illustrated circuit. The switch S1 is a schematic representation of the power plunger switch 324, the actuation of which is described above in relation to FIGS. 6A to 6C. Therefore, when switch S1 in FIG. 8A is closed, VCC power is supplied to the various components of the alarm circuit shown in FIG. 8A, with the power filtered through the capacitor and resistor combination C6 and R10.
In FIG. 8A, the dashed-line box indicated as reference 890 generally represents (schematically) the alarm switch 118 (detailed in FIGS. 7A to 7E) and its interconnections with the alarm system of the EAS tag 100, and the dashed-line box indicated as reference 880 generally represents (schematically) the adjustable piece 108 and its interconnections with the alarm system of the EAS tag 100.
As stated above, the first or main member 104 accommodates an alarm switch 118 that actuates upon securing the article within the gap 110. That is, the alarm switch 118 is actuated when a portion of the article is inserted within the “clips” and the body of the article is pressed against the alarm switch 118 that is protruded from the first or main member 104. Actuation of the alarm switch 118 sets the alarm of the alarm system. Therefore, the switch S3 (representing the alarm switch 118) closes upon securing the article within the gap 110. When the switch S3 is closed by the push of the article within the gap 110, the output of the switch S3 is pulled low or to ground and set to “0” from a high VCC via the current limiting resistor R30, and inputted to a first input line 814 of one or more input lines of a microprocessor 826 for activation (or arming) of the alarm tag 100. In general, output of the various modules pulled low or ground and set to “0” instruct the microprocessor 826 to arm the alarm. Therefore, when fully closed, the power switch 51 enables supply of power from the power source to the alarm system, and the output of the alarm switch S3 pulled low and set to “0” instructs the microprocessor 826 to arm the alarm.
As stated above, the dashed-line box indicated as reference 880 generally represents the adjustable piece 108 and its interconnections with the alarm system of the EAS tag 100. As further illustrated in FIG. 8A and described in detail above, the second distal end 346 of the adjustable piece 108 is coupled with the PCB, which is schematically represented by the switch S2 for better understanding. The switch S2 is virtual and is for illustrative purposes only. Switch S2 is used only to represent the open and closed circuit conditions of the adjustable piece 108 when the lanyard has a complete loop (i.e., switch S2 is closed) or when it is severed (i.e., switch S2 is opened). Therefore, the illustrated switch S2 is not real, but is a mere circuit representation of open or closed condition of the lanyard 108 closed loop circuit. Accordingly, the normal representation of this virtual “switch S2” is in its closed position (as shown in FIG. 8B) as soon as the second distal ends 346 of the inner and outer conductors are permanently connected to the input line 858 of the microprocessor 826 via the Printed Circuit Board (PCB). Therefore, the closed switch S2 represents a complete, internally short-circuited, electrically closed-circuit loop of the lanyard 108 at its first distal ends 345 (encapsulated 344 within spool 504 as shown, and within the main member 104), with its second distal ends 346 connected to the PCB (also within main member 104), with one of the conductors connected to the microprocessor 826 (via line 858) and the other connected to the ground GND. When the switch S2 is closed (i.e., the first distal ends of the insulated inner and insulated outer conductors are electrically and mechanically connected together and the second distal ends of the adjustable piece 108 are mechanically and electrically connected to the input line 858 of the microprocessor 826 via the mechanical connection to the PCB and the ground), the output of the final connection (or the representative closed switch S2 shown in FIG. 8B) is pulled low and set to “0” via the current limiting resistor R5, and inputted to the input line 858 of one or more input lines of a microprocessor 826 for activation (or arming) of the alarm device of the EAS tag 100. With this configuration, the adjustable piece 108 is permanently connected to the reel mechanism of the main member 104 at its first end 345, looped through the second member 106, and permanently connected with the microprocessor 826 at its second end 346. Accordingly, in normal conditions (activated alarm or not), the virtual switch S2 will always remain closed as shown in FIG. 8B. However, as best illustrated in FIG. 8C, if the adjustable piece 108 is severed to release an article, even the use of jumper cables 884 will not prevent the sounding of an alarm. That is, jumper cable 884 may maintain the electrical circuit loop closed for the outer conductor only, but not the insulated inner conductor that is within and inside the outer conductor, and insulated from the outer conductor by a dielectric layer. That is, the jumper 884 may be mechanically and electrically connected to the severed ends of the 891 and 892 of the outer conductor, with the inner conductor severed and insulated from the outer conductor and the jumper 884. Therefore, when severing the lanyard 108 to disconnect and discontinue the physical loop to remove the secured article, the inner conductor will remain open circuited (symbolically represented as the open switch S2 in FIG. 8C) when lanyard 108 is cut, even if cable jumpers 884 are used. The open circuit condition (symbolically represented as the open switch S2) will pull the input line 858 to a high (“1”), which, in turn, will trigger the alarm.
Referring back to FIG. 8A, the alarm system further includes the general purpose microprocessor 826 mounted onto a PCB with an internal memory (e.g., an EEPROM) that includes a set of instructions. The microprocessor 826 receives one or more input signals from one or more input periphery devices and generates one or more processed output signals for actuation of one or more periphery output devices. The processing of data may include Analog to Digital (A/D) or D/A conversion of signals, and further, each input or pin of the microprocessor 826 may be coupled with various multiplexers to enable processing of several multiple input signals from different input periphery devices with similar processing requirements. Non-limiting examples of one or more input periphery devices may exemplarily include the power switch S1, the adjustable piece 108 (represented by the switch S2), the arming mechanisms S3, and the one or more transponders 502a to 502N. Non-limiting examples of one or more output periphery devices may exemplarily include the use of vibration mechanisms, audio, visual or any other indicators to alarm and notify a user regarding an occurrence.
As exemplarily illustrated in FIG. 8A, the EAS tag 100 may use a first module in the form of the electronic article surveillance (EAS) transponders 502a coupled with an EAS connector CON 1, with the EAS transponders 502a comprised of a ferrite coil antenna that includes an inductor L1 and a capacitor C2. It should be noted that several transponder antennas 502a to 502N may be used, with each tuned to a different resonant frequency for activation of different types of pedestals, non-limiting examples of which may include AM, RF, Microwave, and etc.
As illustrated, a first output of the EAS connector CON 1-1 is coupled with ground, and a second output of the EAS connector CON 1-2 is coupled with an amplifier 801 to generate an amplified signal from the EAS transponder 502a. The amplifier increases the signal strength from the EAS transponder 502a sufficiently for further processing by the alarming circuit. The amplifier is comprised of a current limiting resistor R1 that limits the current input to the base of the transistor Q1, with the transistor Q1 functioning to amplify the signal from EAS connector CON 1-2. The transistor Q1 is comprised of an exemplary NPN Bipolar Junction Transistor (BJT), with the collector coupled to power supply VCC and the emitter coupled to ground via a resistor-capacitor filter. It should be noted that present invention should not be limited to the amplifier illustrated, and other conventional amplifiers may also be used. Further, the amplification need not be performed by the BJT, but can be done by other transistors, such as Metal Oxide Semiconductors (MOS) or MOS field effect transistors (MOSFETS), operational amplifiers, transformers, or the like, other passive or active devices, or any combination thereof.
The output of the EAS transponder 502a is amplified by the amplifier 801, and the amplified signal (form the emitter of the transistor Q1) is input to the microprocessor 826 via the input line 816 as one of one or more input signals, where the microprocessor 826 converts the analog amplified signal into a digital signal for processing. This signal is translated by the instructions (algorithm) within the EEPROM of the microprocessor 826 to determine if the signal came from the transmitters (pedestals); if so, the microprocessor 826 will trigger the alarm (e.g., an audio and or visual indicator). It should be noted that one or more of the one or more processed output signals may be pulsed output signals on output line (pin 8) to one of the one or more periphery output devices, for example, for actuation of a transducer unit 840 to generate an audio alarm signal.
The transducer unit 840 is actuated by an amplified pulsed output signal that is output from the microprocessor 826 via line (pin 8), and further amplified by an output amplifier 852. The output amplifier 852 is comprised of a BJT transistor Q3 with an emitter coupled to ground, a collector coupled to a transformer T2 of the transducer 840, and a base that is coupled with a current limiting resistor R9. The transistor Q3 amplifies the pulsed output signal from line (pin 8) to alternately drive the transformer from high VCC to ground and vice versa, with the transformed pulse driving a ceramic transducer to generate an audible alarm. It should be noted that a software routine within the microprocessor generates this pulsed output, which is amplified by the transistor Q3. In addition to the generation of an audible alarm, as further illustrated, other output periphery devices may include the use of a visual indicator D1 that use LEDs 130 to notify users of an occurrence. The visual indicator D1 is coupled with line pin 9 of the microprocessor 826. As indicated above, other output periphery devices not illustrated may also easily be accommodated and connected with the microprocessor 826.
As further illustrated, pins 1 and 14 of the microprocessor 826 are coupled to VCC and ground via a filter capacitor C4, which power the microprocessor 826. The microprocessor 826 is further coupled via its pin 2 to ground through another filter capacitor C3. The crystal X1 coupled to pin 13 is used to facilitate a clocking signal to the microprocessor 826. That is, it stabilizes the frequency of the clock in the microprocessor 826. Pins 10 and 11 are respectively for reset and test of the microprocessor 826, which is through a connector CON 3 that enables the testing and reset of the microprocessor 826. The testing and reset enable determination of signaling of the microprocessor 826, for example, to determine if the microprocessor 826 functions based on “0” or “1” input signal level to trigger a device. In this exemplary instance, the microprocessor 826 will trigger an output periphery device when the input is pulled to high (or “1”). For example, when the adjustable piece 108 is cut, the switch S2 is opened, pulling the line 858 to Vcc (high or “1”), which triggers an alarm. The reset pin 10 is coupled with the reset circuit 832, which includes a current limiting resistor R7 that is coupled at one end to Vcc and other end to a capacitor C5, with the other end of the capacitor C5 coupled to ground. The reset pin 10 is coupled with at the junction of the resistor R7 and capacitor C5.
FIG. 9 is an exemplary flowchart, which illustrates the power management and functionality of the microprocessor 826 for the EAS tag 100. As illustrated, upon start of the program at the operational functional act 902, the microprocessor 826 at the next operational functional act 904 determines if the power plunger switch S1 is closed. If the microprocessor 826 determines that the power plunger S1 is closed, then it initializes at the operational functional act 906, and at the operational functional act 912 the microprocessor 826 determiners if supplied power is greater than a first threshold level. If at the operational functional act 912 it is determined that supplied power is not greater than a first threshold level, the device is non-functional (operational functional act 914). Otherwise, if at the operational act 912 the microprocessor 826 determines that supplied power is greater than the first threshold, the microprocessor 826, at the operational functional act 916, determines if the supplied power is greater than a second threshold level, with the second threshold level greater than the first threshold level. If the microprocessor 826 determines that the supplied power is not greater than a second threshold level, the microprocessor 826 at the operational act 918 activates various output periphery units in certain manner to indicate low supply of power, but continues and activates the alarm to protect an article. If the microprocessor 826 determines that the supplied power is greater than the second threshold level, the microprocessor 826 at the operational functional act 908 determines if the alarm switch S3 is closed. If so, the alarm is set (or armed), and various indicators are activated to indicate to user that the article is protected (operational functional act 910). If the switch S3 is not closed, then initialization process 906 is repeated.
To continue with the flowchart of FIG. 9, the microprocessor 826 at the operational act 922 determines if an antenna signal is received from any one of one or more transponders 502a to 502N. If the microprocessor 826 determines that such an antenna signal is received, at the operational act 924 the microprocessor 826 activates (or triggers) and sounds an alarm. A non-limiting example for such an alarm incident (or condition) is the actual removal of the article to which the EAS tag 100 is connected from a store, passing them through a surveillance zone. This will activate at least one of the one or more transponders 502a to 502N to trigger a signal, which will be amplified (via the amplifier 801) and input to the microprocessor 826 to activate (or trigger the alarm). If the microprocessor 826 determines that no such antenna signal was received, the microprocessor 826, at the operational functional act 926 determines if the adjustable piece 108 has been cut or the alarm plunger switch S2 is open. If the microprocessor 826 determines that the cable is cut and or the alarm plunger switch S3 is open, at the operational act 924 the microprocessor 826 activate (or triggers) the alarm, which indicates an actual tampering of the EAS tag 100. On the other hand, if the microprocessor 826 determines that the adjustable piece 108 is not cut and the alarm plunger switch S3 is still closed, at functional act 930 a determination is made regarding a timer to determine if a predetermined time has been reached. If at operational functional act 930 it is determined that a predetermined time has elapsed, an indicator is output and the timer is reset at operational functional act 931, where the microprocessor 826 then repeats operational functional act 912. The output indicator 932 is an audio and or visual indicator that enables a user to determine if the tag 100 is properly armed. The microprocessor 826 output a visual and or audio indicator periodically (while the EAS tag 100 is armed) at specified predetermined time intervals T.
Although the invention has been described in considerable detail in language specific to structural features and or method acts, it is to be understood that the invention defined in the appended claims is not necessarily limited to the specific features or acts described. Rather, the specific features and acts are disclosed as exemplary preferred forms of implementing the claimed invention. Stated otherwise, it is to be understood that the phraseology and terminology employed herein, as well as the abstract, are for the purpose of description and should not be regarded as limiting. Therefore, while exemplary illustrative embodiments of the invention have been described, numerous variations and alternative embodiments will occur to those skilled in the art. For example, the EAS tag 100 illustrated would be fully functional without the adjustable piece 108 and or the second member 106. That is, the theft-deterrent tag 100 may only comprise of the main member 104 with the article secured with the gap 110. Alternatively, the EAS tag 100 may only comprise of the main member 104 and the adjustable piece 108 as described above. As still another example, the microprocessor 826 and the circuit topography illustrated in FIG. 8A may be designed so that the output of the various modules pulled high and set to “1” instruct the microprocessor 826 to arm the alarm. Such variations and alternate embodiments are contemplated, and can be made without departing from the spirit and scope of the invention.
It should further be noted that throughout the entire disclosure, the labels such as left, right, front, back, top, bottom, forward, reverse, clockwise, counter clockwise, up, down, or other similar terms such as upper, lower, aft, fore, vertical, horizontal, oblique, proximal, distal, parallel, perpendicular, transverse, longitudinal, etc. have been used for convenience purposes only and are not intended to imply any particular fixed direction or orientation. Instead, they are used to reflect relative locations and/or directions/orientations between various portions of an object.
In addition, reference to “first,” “second,” “third,” and etc. members throughout the disclosure (and in particular, claims) is not used to show a serial or numerical limitation but instead is used to distinguish or identify the various members of the group.
In addition, any element in a claim that does not explicitly state “means for” performing a specified function, or “step for” performing a specific function, is not to be interpreted as a “means” or “step” clause as specified in 35 U.S.C. Section 112, Paragraph 6. In particular, the use of “step of,” “act of,” “operation of,” or “operational act of” in the claims herein is not intended to invoke the provisions of 35 U.S.C. 112, Paragraph 6.
