Description
MERCHANDISE SECURITY TAG
BACKGROUND OF THE INVENTION
The invention generally pertains to signal communications and is particularly directed to improved merchandise security tags.
Prior art merchandise security tags include electronic article surveillance (EAS) tags. EAS tags include an EAS sensor that causes an alarm to be sounded when an article of merchandise to which an EAS tag has been attached is moved past an EAS tag detector without first either deactivating the EAS tag or removing the EAS tag from the article of merchandise. EAS tags are described in United States Patents Nos. 4,481,428 and 5,517,179.
Typically an EAS tag is attached to an article of merchandise and is detached therefrom by store personnel and/or the EAS tag is deactivated during a typical check-out process. Thieves sometimes attempt to remove an EAS tag from an article of merchandise by tampering with whatever mechanisms, such as pins, that are used to attach the EAS tag to the article of merchandise.
During theft of merchandise the thief often conceals an article of merchandise. The act of concealment results in an abrupt decrease in the level of light to which the article of merchandise is exposed. Also, the act of theft involves movement of the article of merchandise that is inconsistent with various routine patterns of movement with which articles of merchandise are known to move while being handled by store personnel and by customers during a typical process of paying for the article and carrying the article from the place of sale.
SUMMARY OF THE INVENTION
The invention provides a merchandise security tag, comprising: a light sensor adapted for being coupled to an article of merchandise and for providing a light-level signal indicative of a light level to which the light sensor is being exposed; a microprocessor for processing the light-level signal and to provide a warning signal upon determining that the light-level signal indicates the light sensor is being exposed to a light level less than a selected threshold; and a sound-emitting device coupled to the microprocessor for emitting a particular sound when the microprocessor provides a warning signal. The invention also provides a merchandise security tag, comprising: a motion sensor adapted for being coupled to an article of merchandise for providing a motion signal indicating a pattern of movement of said article of merchandise; a microprocessor coupled to the motion sensor for processing the motion signal and for providing a warning signal upon determining that the indicated pattern of movement is inconsistent with selected particular routine patterns of movement of said article of merchandise; and a sound-emitting device coupled to the microprocessor for emitting a particular sound when the microprocessor provides a said warning signal.
An exemplary embodiment of the invention includes such a motion sensor and such a light sensor and a microprocessor that is adapted for processing both the light- level signal and the motion signal and for providing a warning signal upon determining both that the indicated pattern of movement is inconsistent with selected particular routine patterns of movement of the article of merchandise and that the light-level signal indicates the light sensor is being exposed to a light level less than the selected threshold.
Additional features of the invention are described with reference to the detailed description of the preferred embodiments.
BRIEF DESCRIPTION OF THE DRAWING The sole figure of the Drawing is a functional diagram of an exemplary embodiment of a merchandise security tag according to the invention.
DETAILED DESCRIPTION
Referring to the sole figure of the Drawing, an exemplary embodiment of a merchandise security tag according to the invention includes a light sensor 10, a motion sensor 12, a microprocessor 14, a sound emitter 16, an EAS tag and a battery 18.
The EAS tag includes an RF signal sensor 20 and an RF signal emitter 22. The RF signal sensor 20 is tuned to sense an RF signal at a first frequency, such as 132 KHz, and the RF signal emitter 22 is tuned to emit an RF signal at a second frequency that is one-half the first frequency when the signal sensor 20 senses an RF signal at the first frequency. Unless the EAS tag is deactivated, such an EAS tag will be detected by an EAS detector positioned at an exit from a place where EAS-tagged merchandise is sold or displayed when the EAS detector emits an RF signal at the first frequency in response to detecting an RF signal at the second frequency, whereupon the EAS detector causes an alarm to be provided.
The exemplary embodiment of a merchandise security tag further includes an attachment-tampering sensor 24, which detects any strain upon a tag- attachment mechanism, such as a pin, by which the EAS tag is attached to the article of merchandise
and provides an attachment-tampering signal 26. The microprocessor 14 is adapted for processing the attachment-tampering signal 26 and to provide a warning signal 30 to the sound emitter 16 upon determining that the magnitude of the detected attachment tampering signal 26 exceeds a selected threshold. The light sensor 10 provides light-level signal 28 that is indicative of a light level to which the light sensor 10 is being exposed.
The microprocessor 14 is adapted for processing the light-level signal 28 and to provide a warning signal 30 to the sound emitter 16 upon determining that the light-level signal indicates the light sensor 10 is being exposed to a light level less than a selected threshold.
The sound emitter 16 is coupled to the microprocessor 14 and responds to the warning signal 30 by emitting a particular sound for a selected duration to motivate a potential shoplifter to return the article of merchandise to its original place of display.
The particular sound may be a chirping sound, a clicking sound, a distinctive tone or some other sound that is not typical at the place of sale or display. An exemplary sound emitter includes a piezo sound amplifier, such as one having a 3 -volt piezo element of 1000 ohm.
The motion sensor 12 is adapted for being coupled to an article of merchandise and for providing a motion signal 32 indicating a pattern of movement of the article of merchandise. An exemplary example of a motion sensor is model No. SQ — SEN-200 tilt and vibration sensor sold by SignalQuest LLC, #10 Water Street, Lebanon, NH 03766 USA. Another exemplary motion sensor is an inertial motion sensor including semiconductor ball bearings in an electrode cage.
The microprocessor 14 is further adapted for processing the motion signal 32 and for providing a warning signal 30 upon determining either that the indicated pattern of movement is inconsistent with selected particular routine patterns of movement of the article of merchandise or that both the indicated pattern of movement is inconsistent with the selected particular routine patterns of movement of the article of merchandise and that the light-level signal indicates the light sensor is being exposed to a light level less than the selected threshold. The selected particular routine patterns of movement of the article of merchandise within the particular place of sale or display are stored in the memory of the microprocessor 14. The selected threshold of the light- level signal is also stored in the memory of the microprocessor 14.
The microprocessor 14 and the sound emitter 16 are adapted for causing the particular sound to be emitted at a low level for a selected duration and for causing the particular sound to be terminated when the microprocessor 14 determines during the selected duration that both that the indicated pattern of movement is no longer inconsistent with selected particular routine patterns of movement of the article of merchandise and that the light- level signal no longer indicates the light sensor 10 is not being exposed to a light level less than said selected threshold.
The microprocessor and the sound-emitting device are further adapted for causing the particular sound to be emitted at a higher level when the microprocessor does not determine during the selected duration that both the indicated pattern of movement is no longer inconsistent with selected particular routine patterns of movement of the article of merchandise and that the light-level signal no longer indicates the light sensor is not being exposed to a light level less than said selected threshold.
In one exemplary embodiment, the microprocessor 14 and the sound emitter 16 are adapted for causing the particular sound to be emitted at a low level for a selected duration and for thereafter causing an alarm signal to be provided if the microprocessor 14 and/or the sound-emitting device are not reset during said selected duration. The sound emitter 16 responds to the warning signal by emitting the particular sound for a selected duration in order to motivate a potential shoplifter to return the article of merchandise to its original place of display.
The merchandise security tag is powered by the battery 18.
When a person begins shoplifting an article of merchandise, to which the security merchandise tag of the invention is attached, by so handling the article of merchandise that the light level detected by the light sensor 10 falls below the selected light-level threshold, the microprocessor 14 causes the sound emitter 16 to emit the particular sound. A person then handling the article of merchandise can cause the particular sound to be terminated by so handling the article of merchandise within a selected duration that the light level detected by the light sensor 10 and the motion detected by motion sensor 12 no longer cause the microprocessor 14 to cause the sound emitter 16 to emit the particular sound, such as by returning the article of merchandise to a position of display at the place of sale and/or display.
The particular level of sound initially emitted by the sound emitter 16 preferably will be such that the emitted sound will be recognizable by only the person handling the article of merchandise, and/or nearby store staff and/or knowledgeable customers; and if the attached article is taken out of store before the EAS sensor is deactivated, the EAS
sensor within the tag will cause an alarm to be provided by the EAS detector at the exit from the place of sale and/or display.
