Example embodiments described herein generally related to security technology, and more particularly, relate to a security device for use in retail loss prevention.
Product security devices are commonly used in a number of settings, including in retail theft prevention. In this regard, retail theft prevention systems, often referred to as electronic article surveillance (EAS) systems, use antennas located at the exits of a retail establishment to detect radio frequency (RF) signals emitted by a security device that is coupled to items for sale. A product security device may be affixed or locked to or around a product, and if the device is not removed at a point-of-sale during a sales transaction, the security device will be detected by the EAS system as the device, which is affixed to the product, leaves the store. An alarm may be triggered because the removal of the device from the retail establishment is likely to be associated with an attempted theft. However, if a thief should manage to remove a product from a retail establishment, despite the alarms, the thief may be able to use tools or more complex techniques to remove the security device from the product without damaging the product, thereby permitting the stolen product to be used or resold.
According to some example embodiments, a security device is provided. The example security device may comprise a container. The container is configured to receive an article within the container. The security device may further comprise a locking assembly affixed to the container. The locking assembly may be configured to lock the container to inhibit access to the article and unlock the container to permit access to the article. The security device may also include an electronic assembly affixed to the container. The electronic assembly may comprise a radio frequency receiver and processing circuitry. The processing circuitry may be coupled to the radio frequency receiver. Further, the security device may comprise a benefit denial assembly comprising a canister and a release mechanism. The canister may comprise a substance is disposed within the canister. The release mechanism may be configured to release the substance into the container. The release mechanism may be coupled to and triggerable by the processing circuitry. The processing circuitry may be configured to receive a gate detected signal from the radio frequency receiver in response to the radio frequency receiver receiving a wireless signal and, in response to receiving the gate detected signal from the radio frequency receiver, transmit a release signal to the release mechanism to trigger the release mechanism to release the substance.
According to some example embodiments, an example method is provided. The example method may comprise receiving, at processing circuitry of an electronic assembly, a gate detected signal from a radio frequency receiver of the electronic assembly in response to the radio frequency receiver receiving a wireless signal, and, in response to receiving the gate detected signal from the radio frequency receiver, transmitting a release signal to a release mechanism of a benefit denial assembly to trigger the release mechanism to release a substance disposed within the canister of the benefit denial assembly into a lockable container, wherein an article is disposed within the lockable container.
Having thus described the some example embodiments in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
Some example embodiments now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all example embodiments are shown. Indeed, the examples described and pictured herein should not be construed as being limiting as to the scope, applicability or configuration of the present disclosure. Rather, these example embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like reference numerals refer to like elements throughout. As used herein, operable coupling should be understood to relate to direct or indirect connection that, in either case, enables functional interconnection of components that are operably coupled to each other.
According some example embodiments, an example security device for deterring retail theft by having functionality to release a substance to interface with the product as a benefit denial technique is provided. The example security device may comprise a lockable container within which, a retail product may be secured. The security device may also include an electronic assembly comprising a radio frequency (RF) receiver, such as, an electronic article surveillance (EAS) tag. The electronic assembly may also include processing circuitry. Further, the security device may include a benefit denial assembly comprising a canister filled with a substance, such as for example, an expanding foam. The benefit denial assembly may further include a release mechanism configured to release the substance into the container to interact with the product in response to a theft condition. According to some example embodiments, releasing the substance may include opening an orifice in the canister (e.g., by piercing the canister). The release mechanism may be coupled to and triggerable by the processing circuitry. In this regard, the processing circuitry may be configured to trigger the release mechanism in response to receiving an indication that the RF receiver received a wireless signal from, for example, an EAS gate installed at an exit of a retail establishment, which would indicate a possible theft. The triggered release mechanism may release the substance into the canister to fill the container with the substance in the canister. The substance may interact with the retail product in the container to either damage or adhere to the product to perform a benefit denial function.
Referring to
Security device 10 may be adapted to receive an article, such as items of merchandise including CD or DVD packages, or the security device 10 may be configured to hold other items of merchandise such as computer software boxes, books, jewelry boxes, electronics boxes and the like. Base 12 is typically manufactured from a transparent material that allows the customer to view the article held within security device 10. Base 12 may include a front wall 24, back wall 26, and opposing left and right side walls 28 which extend upwardly and outwardly away from a bottom wall 30. Walls 24, 26, 28 and 30 may be disposed in the form of a five-sided frame or box having an open end disposed opposite bottom wall 30.
Lid 14 may be pivotally connected to base 12 by hinges 16 which may be rotatable about hinge-pins 16a. Lid 14 may close the open end of the box when lid 14 is in the closed position and may allow access to the interior cavity of the box when lid 14 is in the open position. Lid 14 may be manufactured from an opaque material so that, for example, an observer cannot determine if an EAS tag is present within lid 14 and also cannot view the various components of the locking assembly for securing security device 10 in a closed and locked position. Lid 14 may be locked to base 12 by any suitable locking assembly or mechanism including mechanically-actuated devices and magnetically actuated devices. However, an example of a suitable locking mechanism is the mechanism shown and described in pending U.S. patent application Ser. No. 10/371,570, filed Dec. 21, 2003, now U.S. Pat. No. 7,194,879. The entire specification of application Ser. No. 10/371,570 is incorporated herein by reference.
Lid 14 may be locked to base 12 by a slider 32, which may be slidably secured to an interior surface of lid 14, and by a locking assembly 18 (
Slider 32 may include a plurality of spaced L-shaped lock tabs 40 which are shown in
Lid 14 is also provided with an aperture 48 which receives a speaker grille 50 and light post 52 of electronic assembly 20; and is furthermore provided with a pair of alignment indicators 54 which are used to correctly position key 22. Speaker grille 50 and light post 52 may be integrally formed with a battery holder assembly 56 (
Battery holder assembly 56 is provided with the circuitry and other components of electronic assembly 20. In particular, battery holder assembly 56 may include at least a pair of switches 68, 70; a solid state circuit board 72 which substantially controls the electronic assembly; a battery 74 and associated battery cover 76, battery terminals 78; a speaker 80 (FIG. 10) a light-emitting diode (LED) 82 positioned to emit light toward light post 52; and the EAS tag 84. The LED 82 may be designed to flash when electronic assembly 20 is activated. The EAS tag 84 may be radio frequency (RF) sensitive or magnetically sensitive (AM) and is designed to actuate a security gate alarm when it is detected by the security gate. In this regard, the EAS tag 84 may be an example of an RF receiver 113 (
Although not specifically shown in the attached figures, electronic assembly 20 also includes a plurality of sensors connected to circuit board 72. The sensors may monitor the state of the electric circuit in the system and indicate when the circuit is broken. In the event of an interruption in the circuit, a signal is sent by the circuit board 72 to sound the internal audible alarm in the system.
The security device 10 may be used in the following manner. When locking assembly 18 is in the unlocked position (
In order to prevent the electronic assembly from being triggered to sound an alarm after the merchandise has been legally purchased by the customer, security device 10 can be disarmed by aligning key 22 with locking assembly 18. Key 22 may be correctly aligned on security device 10 by protrusions 90 (
With reference now to
In this regard, the processing circuitry 110 may be directly or indirectly connected to an RF receiver 113. The RF receiver 113 may be an EAS tag, such as EAS tag 84. In this regard, the RF receiver 113 may be configured to receive a wireless signal emitted by a EAS security gate at an ingress or egress to a retail establishment. The RF receiver 113 may receive the signal from the EAS security gate when the security device 10 is in relatively close proximity to the EAS security gate, and therefore an ingress or egress to the retail establishment. The RF receiver 113 may be configured to operate at frequencies that are common for EAS security gates, such as, for example, about 8.2 MHz or about 58 kHz. The RF receiver 113 may comprise and inductor and a capacitor that form an LC tank circuit that resonates to transmit a return signal to the EAS security gate to trigger an alarm at the EAS security gate.
The RF receiver 113 may also be directly or indirectly connected to the processing circuitry 110. In this regard, the processing circuitry 110 may be configured to monitor the RF receiver 113 to determine whether the RF receiver 113 has received a wireless signal from an EAS security gate. In response to receiving a wireless signal from an EAS security gate, the RF receiver 113 may be configured to provide a gate detected signal to the processing circuitry 110 for receipt by the processing circuitry 110. Receipt of the gate detected signal at the processing circuitry 110 may operate to initiate a number of functionalities of the security device 10 as further described herein.
For example, the receipt of the gate detected signal may cause the processing circuitry 110 to trigger functionalities associated with the benefit denial assembly 120. The benefit denial assembly 120 may be disposed within the security device 10, and more specifically, within the lid 14. The benefit denial assembly 120 may comprise a release mechanism 122 and a canister 121. The canister 121 may be a tube or containment device (e.g., formed of aluminum) for encasing a substance, such as, for example, an expanding foam substance 123 (e.g., polyurethane foam). According to some example embodiments, the substance may be a liquid or a gel that may mark, damage, deface, or adhere to the article within the container (e.g., bleach, dye, or the like). According to some example embodiments, the substance may be one that changes state from a liquid or gel to a solid when released into the container and exposed to air, the environment, or a change in pressure or temperature. In this regard, the canister 121 may be pressurized. The release mechanism 122 may be an apparatus that is controlled by the processing circuitry 110 to release a substance into the container of the security device. In this regard, for example, the release mechanism 122 may be configured to release the substance by opening an orifice in the canister 121 to release, in this example, the expanding foam substance 123, into the container and more specifically the base 12 of the security device 10 to engage, damage, or prevent removal of the article in the security device 10, thereby performing a benefit denial function in the event that the article, with the security device 10, are attempted to be stolen.
According to various example embodiments, the release mechanism 122 may be configured to operate in a number of different ways to release the substance into the container of the security device 10 in response to receiving a release signal from the processing circuitry 110. According to some example embodiments, the substance may, for example, be pumped, using a pump device that is part of the release mechanism 122 and controlled by the processing circuitry 110 using the release signal, into the container of the security device 10. In this regard, the processing circuitry 110 may control a component, such as a piezo, to cause a vibration that creates a pump action to agitate and release the substance from the canister 121. According some example embodiments, the substance may be released by opening an orifice in the canister 121. In this regard, the release mechanism 122 may be configured to receive a release signal from the processing circuitry 110 and, in response, perform a mechanical actuation to open an orifice in the canister 121. The mechanical actuation may be, for example, to control a solenoid to release a biased pin towards the canister 121 to pierce the canister 121 and thereby open the orifice in canister 121. Alternatively, the canister 121 may be outfitted with a nozzle, and the processing circuitry 110 may be configured to transmit the release signal to an actuator, such as a motor that turns to engage the nozzle or otherwise moves the nozzle to open the orifice in the canister 121 to release the expanding foam substance 123. Further, according to some example embodiments, the canister 121 may include a plug and the release mechanism 122 may be configured to actuate a motor, solenoid, or the like to remove the plug from the canister 121 to open the orifice in the canister 121.
According to some example embodiments, a timer delay may be employed by the processing circuitry 110 prior to transmitting the release signal to the release mechanism 122. In this regard, the processing circuitry 110 may be further configured to, in response to receiving the gate detected signal from the radio frequency receiver, commence a timer. Accordingly, the processing circuitry 110 may be further configured to transmit the release signal to the release mechanism 122 in response to receiving the gate detected signal from the RF receiver 113 and the timer reaching a threshold value. In this regard, the timer may not be commenced until the processing circuitry 110 receives the gate detected signal and the timer may then count down or up to a threshold value (e.g., zero if counting down). Upon reaching the threshold value, the processing circuitry 110 may proceed to transmit the release signal to the release mechanism 122. According to some example embodiments, the time may reach the threshold value in, for example, one minute, five minutes, or the like. Additionally, according to some example embodiments, the processing circuitry 110 may be configured to direct the audio device to emit a sound (e.g., a repeated short tone) while the timer is running.
By employing a timer as described above, the security device 10 may offer the opportunity to interrupt the benefit denial process, if, for example, store personnel accidentally did not remove the article from the security device 10 after the item had been properly purchased. In this regard, the processing circuitry 110 may be configured to detect an action taken by store personnel in response to such a situation and stop or cancel the timer to avoid release of the expanding foam substance 123. The processing circuitry 110 may therefore be configured to receive a disarm signal and, in response to receiving the disarm signal, stop the timer (i.e., prevent the timer from reaching the threshold value).
The disarm signal may be initiated in a number of ways, according to various example embodiments. For example, the disarm signal may be provided via the switch 70 of the locking assembly 18. In this regard, when the locking assembly 18 is transitioned to the unlocked state (e.g., as described above), a lock actuator 131 (e.g., the slider 32 or the like) may cause the state of the switch 70 to change, thereby providing the disarm signal to the processing circuitry 110. Since, according to some example embodiments, the key 22 is required to transition the locking assembly 18 to the unlocked position, and the key 22 should only be in the possession of the store personnel, the disarm signal, in this regard, may be provided only when store personnel have taken action to disarm the security device 10 to prevent the release of the expanding foam substance 123 into the container.
Alternatively, the disarm signal may be provided to the processing circuitry 110 by the RF receiver 113 or another RF receiver 114. In this regard, for example, the RF receiver 113 may receive a wireless disarm signal (i.e., different from the standard wireless gate signal emitted by an EAS gate, such as, for example, a higher power signal), and provide a disarm signal to the processing circuitry 110. Similarly, the electronic assembly 20 may include a second RF receiver 114, which may include an RF antenna that operates at frequency different than an EAS gate. According to some example embodiments, the RF receiver 114 may be a coil associated with a transformer used to excite the audio device 115 that is monitored by the processing circuitry 110. In this regard, according to some example embodiments, the key 22 may include an RF transmitter configured to transmit a wireless disarm signal to the security device 10. The wireless disarm signal transmitted by the key 22 may be received by the RF receiver 114, and the RF receiver 114 may responsively provide the disarm signal to the processing circuitry 110 to stop the timer.
