[0003] It is common practice for retailers to display relatively
small, relatively expensive items of merchandise on a security
device, such as a display hook or a display fixture, within
security packaging commonly referred to as a "safer", or otherwise
on a display surface. The security device or safer displays an item
of merchandise so that a potential purchaser may examine the item
when deciding whether to purchase the item. The small size and
relative expense of the item, however, makes the item an attractive
target for shoplifters. A shoplifter may attempt to detach the item
from the security device, or alternatively, may attempt to remove
the security device from the display area along with the
merchandise. Items of merchandise may also be secured using a
display stand to allow users to sample the item for potential
purchase. In some instances, the security device is secured to a
display support using a lock operated by a key, for example, a
mechanical lock. In other instances, the security device is secured
to the display support using a lock operated by an electronic key
to arm and disarm the security device.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
[0033] Referring now to the accompanying drawing figures wherein
like reference numerals denote like elements throughout the various
views, one or more embodiments of a merchandise display security
system are shown. In the embodiments shown and described herein,
the system includes an electronic key and a merchandise security
device. Merchandise security devices suitable for use with the
electronic keys include, but are not limited to, a security display
(e.g. alarming stand), security fixture (e.g. locking hook, shelf,
cabinet, etc.) or security packaging (e.g. merchandise keeper) for
an item of merchandise. However, an electronic key (also referred
to herein as a programmable key or generally as a key) may be
useable with any security device or locking device that utilizes
power transferred from the key to operate a mechanical and/or
electronic lock mechanism and/or utilizes data transferred from the
key to authorize the operation of a lock mechanism and/or arming or
disarming an alarm circuit. In other words, an electronic key is
useable with any security device or locking device that requires
power transferred from the key to the device and/or data
transferred from the key to the device. Further examples of
security devices and locking devices include, but are not limited
to, a door lock, a drawer lock or a shelf lock, as well as any
device that prevents an unauthorized person from accessing,
removing or detaching an item from a secure location or position.
Although the following discussion relates to a system for use in a
retail store, it is understood that the system is also suitable for
other industries, such as hospital, restaurants, etc. In some
embodiments, the merchandise security device and the electronic key
are similar to those disclosed in U.S. application Ser. No.
13/222,225 filed on Aug. 31, 2011, entitled Electronic Key for
Merchandise Security Device, the disclosure of which is
incorporated herein by reference in its entirety.
[0034] FIG. 1 illustrates one embodiment of a system 10. In this
embodiment, the system generally includes an electronic key 12, one
or more merchandise security devices 14, a programming or
authorization station 16, and a charging station 18. FIG. 2 shows
an embodiment of a system 10 that is part of a network of
merchandise security devices. According to some embodiments, the
network enables communication between a plurality of electronic
keys and merchandise security devices. The network may be
cloud-based and include a cloud 22 for receiving data from, and/or
providing data to, the electronic keys and/or merchandise security
devices. The cloud 22 may facilitate data transfer to one or more
remote locations or devices 26 (e.g., a tablet or computer) where
the data may be reviewed and analyzed. The network may be a mesh
network including a plurality of nodes 20 that are configured to
communicate with one another, one or more electronic keys 12,
and/or one or more merchandise security devices 14. The nodes 20
and/or security devices 14 may be located within one or more zones.
A gateway 24 may be employed to allow for communication between the
one or more nodes 20 and the cloud 22. In some embodiments, all
communication within the network is wireless, such as via
radio-frequency signals (e.g., Sub GHz ISM band or 2.4 GHz),
although other types of wireless communication may be possible.
[0035] In some embodiments, each electronic key 12 is configured to
store various types of data. For example, each key 12 may store a
serial number of one or more merchandise security devices 14, the
data and time of activation of the key, a user of the key, a serial
number of the key, a department number within a retail store,
number of key activations, a type of activation (e.g., "naked"
activation, activation transferring only data, activation
transferring power, activation transferring data and power), and/or
various events (e.g., a merchandise security device has been
locked, unlocked, armed, or disarmed). For instance, FIG. 3 shows
that the identity of a user of an electronic key 12 may be
communicated to a remote location or device 26. This information
may be transmitted to the remote location or device 26 upon each
activation of the key 12 or at any other desired period of time,
such as upon communication with a programming or authorization
station 16. Thus, the data transfer may occur in real time or
automatically in some embodiments. In some cases, the programming
station 16 may be configured to store the data and transfer the
data to a remote location or device 26. Authorized personnel may
use this data to take various actions, such as to audit and monitor
associate activity, determine the battery life of a key 12, audit
merchandise security devices 14 (e.g., ensure the security devices
are locked or armed), etc. Moreover, such information may be
requested and obtained on demand, such as from the programming
station 16.
[0036] In some cases, the data may include battery analytics of an
electronic key 12. For example, the battery analytics may include
monitoring the battery voltage of an electronic key 12 when the key
is placed on a charging station 18 and the time taken to reach full
charge. These values may be used to determine depth of discharge.
The battery analytics may be indicative of a battery that is
nearing its end of life. A retailer or other authorized personnel
may take various actions using this information, such as replacing
the key or disabling the key to prevent battery swelling and
housing failure.
[0037] In one embodiment, the electronic key 12 is configured to
obtain data from a merchandise security device 14 (e.g., a security
fixture). For example, the merchandise security device 14 may store
various data regarding past communication with a previous
electronic key 12 (e.g., key identification, time of communication,
etc.), and when a subsequent electronic key communicates with the
same merchandise security device, the data is transferred to the
electronic key. Thus, the merchandise security device 14 may
include a memory for storing such data. In some cases, the
merchandise security device 14 includes a power source for
receiving and storing the data, while in other cases, the power
provided by the electronic key 12 is used for allowing the
merchandise security device to store the data. The electronic key
12 may then communicate the data for collection and review, such as
at a remote location or device 26. In some instances, communication
between the electronic key 12 and the programming or authorization
station 16 may allow data to be pulled from the electronic key and
communicated, such as to a remote location or device 26. In other
cases, the electronic key 12 may be configured to obtain data from
merchandise security devices 14 (e.g., a security display), such as
an identification of the merchandise security device, the type of
item of merchandise on display, an identification of the item of
merchandise, and/or the system health of the security device and/or
the item of merchandise. The electronic key 12 may store the data
and provide the data to a remote location or device 26 upon
communication with the programming or authorization station 16. As
such, the electronic keys 12 may be a useful resource for obtaining
various types of data from the merchandise security devices 14
without the need for wired connections or complex wireless networks
or systems.
[0038] In some cases, each electronic key 12 may be authorized for
specific locations, departments, or merchandise security devices.
For instance, FIG. 4 shows that a manager may have authorization
for all zones, locations, departments, or merchandise security
devices (indicated as numbers 1-6), while a first associate may
only have authorization for two zones, locations, departments, or
merchandise security devices (indicated as numbers 4 and 5), and a
second associate may only have authorization for one zone,
location, department, or merchandise security device (indicated as
number 6). As such, a retail store or other establishment may limit
the scope of authorization for different associates within the same
retail store. In order to accommodate different authorizations
levels, each key 12 may be configured to store a code that is
associated with each zone, location, department, or merchandise
security device. For example, each zone may include a plurality of
merchandise security devices 14, and a retail store may have
multiple zones (e.g., a zone for electronics, a zone for jewelry,
etc.).
[0039] Various techniques may be used to initially program the
electronic key 12. For example, the electronic key 12 may be
initially presented to each authorized merchandise security device
14. Upon communication with the security device 14 or the cloud 22,
the electronic key 12 will be paired with each security device. A
programming station 16 may provide a code to the electronic key 12,
and the key or cloud 22 may then communicate the code to each of
its authorized security devices 14. Each key 12 may only need to be
programmed once. In some embodiments, a programming station 16 may
be located within each zone, and a key 12 may receive a code from
each programming station that it is authorized. Thereafter, each
key 12 may need to be "refreshed" at the programming station 16 or
a charging station 18 following a predetermined period of time. In
other embodiments, the electronic key 12 may be programmed directly
via the cloud 22.
[0040] In another embodiment, each electronic key 12 may include a
security code and a serial number for one or more merchandise
security devices 14. For example, a key 12 may only be able to arm,
disarm, lock, or unlock a merchandise security device 14 where the
security codes and the serial numbers match one another. In one
example, each serial number is unique to a merchandise security
device 14 and could be programmed at the time of manufacture or by
the retailer. This technique allows for greater flexibility in
programming keys 12 and assigning keys to particular merchandise
security devices 14 and/or zones. In one embodiment, a setup
electronic key 12'' may be used to initially map particular
merchandise security devices 14 and serial numbers. In this regard,
the setup key 12'' may be used to communicate with each key 12 and
obtain the serial number of each merchandise security device 14.
The setup key 12'' may also obtain a location of the security
devices 14, or a user of the setup key may provide a description
for each merchandise security device (e.g., SN #123=merchandise
security device #1). The setup key 12'' may communicate with a
tablet or other computing device 26 for accumulating all of the
information (see, e.g., FIGS. 3 and 19), which may occur via wired
or wireless communication. Thus, the tablet or computing device 26
may map each of the serial numbers with the merchandise security
devices 14 and in some cases, may also include serial numbers and
corresponding electronic keys 12. Individual electronic keys 12 may
then be assigned particular serial numbers for authorized
merchandise security devices 14 (e.g., user 1 includes serial
numbers 1, 2, 3; user 2 includes serial numbers 1, 4, 5). Each of
the electronic keys 12 may be programmed with the same security
code using a programming station 16. In some embodiments, the setup
process may be used in conjunction with a planogram of the
merchandise security devices 14. The planogram may represent a
layout of the merchandise security devices 14 within a retail store
or other establishment. For example, a setup key 12'' may be used
to map serial numbers to specific merchandise security devices 14
on a planogram as the setup key communicates with each merchandise
security device. The setup key 12'' may communicate with a tablet
or other computing device 26 for populating the planogram with
serial numbers, such as via a wired connection (see, e.g., FIG.
19). This planogram may be uploaded to a remote location or device
for managing the planogram. As before, particular serial numbers
may be assigned to authorized users.
[0041] In order to arm, disarm, lock, or unlock a merchandise
security device 14, the electronic key 12 may communicate with a
particular merchandise security device and determine whether the
security codes and the serial numbers match. If the codes match,
the electronic key 12 then arms, disarms, locks, or unlocks the
merchandise security device 14. Upon refreshing an electronic key
12 and/or when a user requests an electronic key via programming or
authorization station 16, any available electronic key may be used
since the key may be programmed in real time with the appropriate
level of authorization for that user (e.g., specific zones,
departments, and/or merchandise security devices).
[0042] In one embodiment, the merchandise display security system
10 comprises an electronic key 12 and a merchandise security device
14 that is configured to be operated by the key. The system may
further comprise an optional programming station 16 that is
operable for programming the key 12 with a security code, which may
also be referred to herein as a Security Disarm Code (SDC). In
addition to programming station 16, the system may further comprise
an optional charging station 18 that is operable for initially
charging and/or subsequently recharging a power source disposed
within the key 12. For example, the key 12 and merchandise security
device 14 may each be programmed with the same SDC into a
respective permanent memory. The key 12 may be provisioned with a
single-use (i.e., non-rechargeable) power source, such as a
conventional or extended-life battery, or alternatively, the key
may be provisioned with a multiple-use (i.e. rechargeable) power
source, such as a conventional capacitor or rechargeable battery.
In either instance, the power source may be permanent,
semi-permanent (i.e., replaceable), or rechargeable, as desired. In
the latter instance, charging station 18 is provided to initially
charge and/or to subsequently recharge the power source provided
within the key 12. Furthermore, key 12 and/or merchandise security
device 14 may be provided with only a transient memory, such that
the SDC must be programmed (or reprogrammed) at predetermined time
intervals. In this instance, programming station 16 is provided to
initially program and/or to subsequently reprogram the SDC into the
key 12. As will be described, key 12 may be operable to initially
program and/or to subsequently reprogram the merchandise security
device 14 with the SDC. Key 12 is then further operable to operate
the merchandise security device 14 by transferring power and/or
data to the device, as will be described.
[0043] In the exemplary embodiment of the system illustrated in
FIGS. 1-2, electronic key 12 is configured to be programmed with a
unique SDC by the programming station 16. In some embodiments, the
key 12 is presented to the programming station 16 and communication
therebetween is initiated, for example, by pressing or otherwise
actuating a control button 28 provided on the exterior of the key.
Communication between the programming station 16 and the key 12 may
be accomplished directly, for example by one or more electrical
contacts, or indirectly, for example by wireless communication. Any
form of wireless communication capable of transferring data between
the programming station 16 and key 12 is also possible, including
without limitation optical transmission, acoustic transmission or
magnetic induction. In some embodiments shown and described herein,
communication between programming station 16 and key 12 is
accomplished by wireless optical transmission, and more
particularly, by cooperating infrared (IR) transceivers provided in
the programming station and the key. In some embodiments, the
programming station 16 may function similarly to that disclosed in
U.S. Pat. No. 7,737,844 entitled PROGRAMMING STATION FOR A SECURITY
SYSTEM FOR PROTECTING MERCHANDISE, the disclosure of which is
incorporated herein by reference in its entirety. For the purpose
of describing some embodiments of the present invention, it is
sufficient that the programming station comprises at least a logic
control circuit for generating or being provided with a SDC, a
memory for storing the SDC, and a communications system suitable
for interacting with the electronic key 12 in the manner described
herein to program the key with the SDC.
[0044] An available feature of a merchandise security system 10
according to one embodiment is that the electronic key 12 may
include a time-out function. More particularly, the ability of the
key 12 to transfer data and/or power to the merchandise security
device 14 may be deactivated after a predetermined time period. By
way of example, the electronic key 12 may be deactivated after
about six to about twenty-four hours from the time the key was
programmed or last refreshed. In this manner, an authorized sales
associate typically must program or refresh the key 12 assigned to
him at the beginning of each work shift. Furthermore, the charging
station 18 may be configured to deactivate the electronic key 12
when the key is positioned within or otherwise engaged with a
charging port 30 (see, e.g., FIG. 1). In this manner, the charging
station 18 can be made available to an authorized sales associate.
In one embodiment, the electronic key 12 may be authorized upon the
sales associate inputting an authorized code to release the key for
use. For instance, the sales associate may input a code on a keypad
in communication with the charging station 18. Upon inputting the
correct code, the charging station 18 may indicate which key 12 is
authorized for use by the sales associate (e.g., via an audible
and/or a visible indicator). In some cases, the time-out period may
be predetermined or customized by a user. For example, a manager of
a retail store may input a particular time period for one or more
of the electronic keys 12. Those electronic keys 12 that are
"active" may be monitored via communication within the cloud-based
network. In other embodiments, the electronic key 12 may be timed
out or otherwise disabled in response to an event. For instance,
the electronic key 12 may be disabled in response to the key being
misplaced or stolen, or keys being brought into a retail store that
are not authorized for use. Such disabling may occur via a command
sent to the electronic key 12 via the cloud 22.
[0045] In one embodiment, commands may be provided remotely for
taking various actions. For example, where a theft has occurred, a
command may be provided from a remote location or device 26 (e.g.,
a tablet or computer) to lock and/or arm all or a portion of the
merchandise security devices 14. Similarly, a command may be
provided from a remote location or device 26 to deactivate all or a
portion of the electronic keys 12. As such, the system 10 provides
techniques for centralized security and control of the electronic
keys 12, merchandise security devices 14, and other components
within the system.
[0046] FIGS. 5-6 illustrate one embodiment of an electronic key 12.
The electronic key 12 may include a control button 28 for
activating the key, such as for initiating communication with a
merchandise security device. Moreover, the electronic key 12 may
also include one or more visual indicators. In this regard, the key
12 may include one or more status indicators 32 that illustrate a
status of the communication of the key with a merchandise security
device 14. The status indicators 32 may guide the user to know when
communication between the key 12 and the merchandise security
device 14 is taking place and has been completed. The status
indicators 32 may be different depending on whether the
communication was authorized (e.g., unlocked or disarmed),
unauthorized (e.g., wrong zone or department), or unsuccessful. The
status indicators 32 may also indicate an amount of time of
authorized use remaining on the key 12, such as where the key
includes a time-out feature as discussed above. The electronic key
12 may also include one or more other indicators 34 that provide a
visual indication of the power remaining on the key. These other
indicators 34 may also be used for any other desired purpose, such
as to indicate a programming state of the key 12. For example, the
indicators 34 may be activated while the electronic key 12 is being
initially programmed It is understood that the illustrated status
indicators 32, 34 are for illustration only, as various types and
configurations of indicators may be employed in alternative
embodiments.
[0047] FIGS. 7-10 illustrate additional embodiments of electronic
keys 12. In these examples, the electronic key 12 includes a
removable portion 36. In FIGS. 7-8, the removable portion 36 allows
access to an input power port 38, such as for recharging the
electronic key 12. The removable portion 36 may be configured to
slide relative to the electronic key 12 to expose the input power
port 38. The input port 38 may be configured to receive and
electrically connect to a corresponding connector, such as a
connector associated with the charging station 18. For instance,
the electronic key 12 may be configured to be docked within the
charging station 18 for charging thereof (see, e.g., FIG. 1). As
shown in FIGS. 9-10, the removable portion 36 may also be
configured to be removed entirely from the electronic key 12 and
may be multi-purpose in that it may be include a tool portion 40.
For example, the tool portion 40 may be used for facilitating the
disconnection of various connectors, as a screwdriver, etc. The
electronic key 12 may include an opening 42 defined to receive the
removable portion 36 therein in a non-use position.
[0048] FIGS. 20-21 show additional embodiments of an electronic key
12'. In this embodiment, the electronic key 12' includes one or
more alignment features 15 for facilitating alignment with a
programming or authorization station 16' and/or a charging station
18' as discussed in further detail below. In addition, the
electronic key 12' includes an input port 17 (e.g., a micro-USB
port) which may be configured to releasably engage a corresponding
port on the programming or authorization station 16' and/or the
charging station 18' for data and/or power transfer. Notably in the
example shown in FIG. 20, the input port 17 on the electronic key
12' is on a side surface, while a pair of alignment features 15 are
provided on opposite surfaces of the electronic key. In the
embodiment shown in FIG. 21, a single alignment feature 15 is
provided. The input port 17 may be located on a side surface
between a transfer port at one end and a key chain ring opening at
an opposite end. Positioning of the input port 17 on a side surface
of the electronic key 12' may provide for a more secure and stable
attachment to the programming or authorization station 16' and/or
the charging station 18'. A series of status indicators 32, 34, as
discussed above, for example light-emitting diodes (LEDs) may be
provided on the exterior of the electronic key 12' for indicating
the operating status thereof.
[0049] As shown in FIG. 1, the programming station 16 comprises a
housing configured to contain the logic control circuit that
generates the SDC, the memory that stores the SDC, and a
communications system for communicating the SDC to the key (e.g.,
wirelessly). In use, the logic control circuit generates the SDC,
which may be a predetermined (i.e. "factory preset") security code,
a manually input security code, or a security code that is randomly
generated by the logic control circuit. In the latter instance, the
logic control circuit further comprises a random number generator
for producing the unique SDC. A series of visual indicators, for
example light-emitting diodes (LEDs) may be provided on the
exterior of the housing for indicating the operating status of the
programming station 16. Programming station 16 may further be
provided with an access mechanism for preventing use of the
programming station by an unauthorized person. For example, the
programming station may include a keypad 44. An authorized user may
input a code in the key pad 44 that allows the programming station
16 to generate a SDC for communicating to the key 12.
[0050] In a particular embodiment, the logic control circuit of the
programming station 16 performs an electronic exchange of data with
a logic control circuit of the key, commonly referred to as a
"handshake communication protocol." The handshake communication
protocol determines whether the key 12 is an authorized key that
has not been programmed previously (e.g., a "new" key), or is an
authorized key that is being presented to the programming station
16 a subsequent time to refresh the SDC. In the event that the
handshake communication protocol fails, the programming station 16
will not provide the SDC to the unauthorized device attempting to
obtain the SDC. When the handshake communication protocol succeeds,
programming station 16 permits the SDC to be transmitted by the key
12. As will be readily apparent to those skilled in the art, the
SDC may be transmitted from the programming station 16 to the key
12 by any suitable means, including without limitation, wireless,
electrical contacts or electromechanical, electromagnetic or
magnetic conductors, as desired. Moreover, in other cases the
programming station 16 may simply provide the SDC to the electronic
key 12 without first initiating any handshake communication
protocol.
[0051] In some embodiments, the merchandise security device 14 is a
"passive" device. As used herein, the term passive is intended to
mean that the security device 14 does not have an internal power
source sufficient to lock and/or unlock a mechanical lock
mechanism. Significant cost savings are obtained by a retailer when
the merchandise security device 14 is passive since the expense of
an internal power source is confined to the key 12, and one such
key is able to operate multiple security devices. If desired, the
merchandise security device 14 may also be provided with a
temporary power source (e.g., capacitor or limited-life battery)
having sufficient power to activate an alarm, for example a
piezoelectric audible alarm, that is actuated by a sensor, for
example a contact, proximity or limit switch, in response to a
security breach. The temporary power source may also be sufficient
to communicate data, for example a SDC, from the merchandise
security device 14 to the key 12 to authenticate the security
device and thereby authorize the key to provide power to the
security device.
[0052] In some embodiments, the merchandise security device 14
further comprises a logic control circuit, similar to the logic
control circuit disposed within the key 12, adapted to perform a
handshake communication protocol with the logic control circuit of
the key in essentially the same manner as that between the
programming station 16 and the key. In essence, the logic control
circuit of the key 12 and the logic control circuit of the
merchandise security device 14 communicate with each other to
determine whether the merchandise security device is an authorized
device that does not have a security code, or is a device having a
matching SDC. In the event the handshake communication protocol
fails (e.g., the device is not authorized or the device has a
non-matching SDC), the key 12 will not program the device with the
SDC, and consequently, the merchandise security device will not
operate. If the merchandise security device 14 was previously
programmed with a different SDC, the device will no longer
communicate with the key 12. In the event the handshake
communication protocol is successful, the key 12 permits the SDC
stored in the key to be transmitted to the merchandise security
device 14 to program the device with the SDC. As will be readily
apparent to those skilled in the art, the SDC may be transmitted
from the key 12 to the merchandise security device 14 by any
suitable means, including without limitation, via radiofrequency,
one or more electrical contacts, electromechanical, electromagnetic
or magnetic conductors, as desired. Furthermore, the SDC may be
transmitted by inductive transfer of data from the electronic key
12 to the merchandise security device 14. Moreover, in other cases
the electronic key 12 may simply provide the SDC to the merchandise
security device 14 without first initiating any handshake
communication protocol.
[0053] In one embodiment, when the handshake communication protocol
is successful and the merchandise security device 14 is an
authorized device having the matching SDC, the merchandise security
device may be armed or disarmed, such as where the security device
includes an alarm circuit. In other embodiments, the merchandise
security device 14 may be armed or disarmed when the SDC codes
match. In some embodiments, when the handshake communication
protocol is successful and the SDC codes match, the logic control
circuit of the key 12 causes an internal power source of the key to
transfer electrical power to the device 14 to operate a mechanical
lock mechanism. In other embodiments, the merchandise security
device 14 may be locked or unlocked when the SDC codes match and
power is transferred to the merchandise security device. It is
understood that various information and codes may be exchanged in
order to perform the desired function, such as arming, disarming,
locking, or unlocking the merchandise security device 14. For
example, the data exchanged may include a serial number of the
merchandise security device alone and/or an SDC.
[0054] FIG. 11 shows one embodiment of a merchandise security
device 140 in greater detail. As previously mentioned, the
merchandise security device 14 can be any type of security device
that utilizes an alarm circuit and/or a lock mechanism that locks
and/or unlocks a lock. In some cases, the merchandise security
device 140 may be a passive device in the sense that it does not
have an internal power source sufficient to operate a lock
mechanism. As a result, the merchandise security device 140 may be
configured to receive power, or alternatively, both power and data,
from an external source, such as the electronic key 12 shown and
described herein. The embodiment of the merchandise security device
depicted in FIG. 11 is a cabinet lock configured to be securely
affixed to the locking arm 104 of a conventional cabinet lock
bracket 105. As previously described, the cabinet lock 140 may
include a logic control circuit for performing a handshake
communication protocol with the logic control circuit of the key 12
and for receiving the SDC from the key. In other embodiments, the
cabinet lock 140 may be configured to transmit the SDC to the key
12 to authenticate the security device and thereby authorize the
key to transfer power to the security device.
[0055] FIGS. 12 show an embodiment of an electronic key 120 with
inductive transfer in greater detail. As previously mentioned, the
key 120 may be configured to transfer both data and power to a
merchandise security device 140. Accordingly, the programmable
electronic key 120 may be an active device in the sense that it has
an internal power source sufficient to operate a mechanical lock
mechanism of the merchandise security device 140. As a result, the
programmable electronic key 120 may be configured to transfer both
data and power from an internal source, such as a logic control
circuit (e.g., data) and a battery (e.g., power) disposed within
the key. The embodiment of the programmable electronic key 120
depicted herein is a key with inductive transfer capability
configured to be received within the transfer port 145 of the
cabinet lock 140 shown in FIG. 11, as well as a programming port 46
of the programming station and the charging port 30 of the charging
station.
[0056] In some embodiments, the electronic key 120 comprises a
housing 121 having an internal cavity or compartment that contains
the internal components of the key, including without limitation
the logic control circuit, memory, communication system and
battery, as will be described. As shown, the housing 121 is formed
by a lower portion 123 and an upper portion 124 that are joined
together after assembly, for example by ultrasonic welding. The
electronic key 120 further defines an opening 128 at one end for
coupling the key to a key chain ring, lanyard or the like. The
electronic key 120 may further comprise a transfer probe 125
located at an end of the housing 121 opposite the opening 128 for
transferring data and/or power to the merchandise security device
140. The transfer probe 125 is also operable to transmit and
receive a handshake communication protocol and the SDC from the
programming station 16, as previously described, and to receive
power from a charging station.
[0057] As best shown in FIG. 13, an internal battery 131 and a
logic control circuit, or printed circuit board (PCB) 132 are
disposed within the housing 121 of the electronic key 120. Battery
131 may be a conventional extended-life replaceable battery or a
rechargeable battery suitable for use with the charging station 18.
The logic control circuit 132 is operatively coupled and
electrically connected to a switch 133 that is actuated by the
control button 122 provided on the exterior of the key 120 through
the housing 121. Control button 122 in conjunction with switch 133
controls certain operations of the logic control circuit 132, and
in particular, transmission of the data and/or power. In that
regard, the logic control circuit 132 is further operatively
coupled and electrically connected to a communication system 134
for transferring data and/or power. In one embodiment, the
communication system 134 is a wireless infrared (IR) transceiver
for optical transmission of data between the electronic key 120 and
the programming station, and between the key and the merchandise
security device 140. As a result, the transfer probe 125 of the key
120 may be provided with an optically transparent or translucent
filter window 135 for emitting and collecting optical transmissions
between the key 120 and the programming station 60, or between the
key and the merchandise security device 140, as required. Transfer
probe 125 may further comprise an inductive core 127 and inductive
core windings 129 for transferring electrical power to the
merchandise security device 140 and/or receiving electrical power
from the charging station 18 to charge the internal battery 131, as
required. Alternatively, the optical transceiver 134 may be
eliminated and data transferred between the programmable electronic
key 120 and the merchandise security device 140 via magnetic
induction through the inductive coil 126.
[0058] In some embodiments, an important aspect of an electronic
key 120, especially when used for use in conjunction with a
merchandise security device 140 as described herein, is that the
key does not require a physical force to be exerted by a user on
the key to operate the mechanical lock mechanism of the merchandise
security device. By extension, no physical force is exerted by the
key 120 on the mechanical lock mechanism. As a result, the key 120
cannot be unintentionally broken off in the lock, as often occurs
with conventional mechanical key and lock mechanisms. Furthermore,
neither the key 120 nor and the mechanical lock mechanism suffer
from excessive wear as likewise often occurs with conventional
mechanical key and lock mechanisms. In addition, in some cases
there is no required orientation of the transfer probe 125 of the
electronic key 120 relative to the ports on any one of the
programming station, charging station, and/or the merchandise
security device 140. Accordingly, any wear of the electrical
contacts on the transfer probe 125 and ports may be minimized As a
further advantage in some embodiments, an authorized person is not
required to position the transfer probe 125 of the electronic key
120 in a particular orientation relative to the transfer port 142
of the merchandise security device 140 and thereafter exert a
compressive and/or torsional force on the key to operate the
mechanical lock mechanism of the device.
[0059] FIGS. 22-24 illustrate an embodiment of a programming or
authorization station 16'. As illustrated, the programming or
authorization station 16' includes a geometry for receiving the
electronic key 12' as discussed above (see, e.g., FIG. 21). In this
regard, the programming or authorization station 16' may include
one or more alignment features 15' configured to align with and
engage alignment feature 15 of the electronic key 12'. Moreover,
the programming or authorization station 16' may further define a
recess 48 for at least partially receiving a side surface of the
electronic key 12'. The recess 48 may be curved or any other shape
for corresponding to the shape of the electronic key 12'. Within
the recess 48, the programming or authorization station 16' may
include a port 30' for releasably engaging the input port 17 of the
electronic key 12'. The alignment features 15, 15' are configured
to align with one another to ensure that the input port 17 and port
30' align with and engage one another. Such engagement may allow
for data communication between the electronic key 12' and the
programming or authorization station 16', which may occur in some
cases, upon entry of an authorized code using keypad 44. In
addition, the programming or authorization station 16' may include
one or more input ports 50 for receiving power and data
communication (e.g., an Ethernet port).
[0060] FIG. 1 shows a charging station 18 in greater detail. As
previously mentioned, the charging station 18 recharges the
internal battery 131 of the key 12. In certain instances, the
charging station 18 also deactivates the data transfer and/or power
transfer capability of the key 12 until the key has been
reprogrammed with the SDC by the programming station 16 or the user
provides an authorized code to the charging station. Regardless,
the charging station 18 comprises a housing for containing the
internal components of the charging station. The exterior of the
housing has at least one, and preferably, a plurality of charging
ports 30 formed therein that are sized and shaped to receive the
electronic key 12 (see, e.g., FIG. 1). Mechanical or magnetic means
may be provided for properly positioning and securely retaining the
key 12 within the charging port 18 for ensuring proper power
transfer.
[0061] FIGS. 16-18 show an embodiment of a charging station 18
wherein a plurality of ports 30 are provided for engagement with a
plurality of corresponding electronic keys 12'. The electronic key
12' shown in FIG. 21 may be compatible with the charging station 18
shown in FIGS. 16-18 whereby the electronic key 12' includes an
input port 17 on its side for engagement with the port 30, similar
to that described in conjunction with programming or authorization
station 16'. Likewise, each port 30 may be located within a
respective recess 48 for receiving at least a side surface of the
electronic key 12'. This arrangement may allow for a greater number
of electronic keys 12' to be engaged with the charging station 18
at any one time.
[0062] FIGS. 14-15 show additional embodiments of a merchandise
security device 150. In this embodiment, the merchandise security
device 150 comprises a lock mechanism that utilizes "energy
harvesting". Thus, the merchandise security device 150 may be a
passive device as described above. However, in this embodiment, the
merchandise security device 150 includes means for generating power
to be stored. For example, the merchandise security device 150 may
be configured to rotate between locked and unlocked positions and
include a generator configured to generate energy to be stored
(e.g., via a capacitor). In some cases, the merchandise security
device 150 may include a bezel and each turn of the bezel may
generate an electrical charge to be stored. In one embodiment, the
electronic key 12 may be used initially to disengage a mechanical
lock, and then the merchandise security device 150 may be rotated
to an unlocked position. The merchandise security device 150 may
then be rotated back to the locked position. Since the merchandise
security device 150 has no power source, the security device is
capable of performing various security functions using the stored
power. For instance, the merchandise security device 150 may be
configured to use the stored power to push data to one or more
nodes 20 or to generate audible and/or visible signals. In one
example, the merchandise security device 150 may include an
internal radio for transmitting wireless signals using the stored
power, such as for generating a distress signal when the security
device is tampered with. In another example, the merchandise
security device 150 may include a light-emitting device (LED) that
is powered by the stored power. In some embodiments, techniques for
energy harvesting may be similar to that described in U.S.
application Ser. No. 13/538,386, the disclosure of which is
incorporated by reference in its entirety.
[0063] The foregoing has described one or more exemplary
embodiments of a merchandise display security system. Embodiments
of a merchandise display security system have been shown and
described herein for purposes of illustrating and enabling one of
ordinary skill in the art to make, use and practice the invention.
Those of ordinary skill in the art, however, will readily
understand and appreciate that numerous variations and
modifications of the invention may be made without departing from
the spirit and scope thereof. Accordingly, all such variations and
modifications are intended to be encompassed by the appended
claims.
