The present invention is directed to an apparatus and method involving a voltage selectable alarm sensor for operably mounting an anti-theft device to an article being monitored. The voltage selectable alarm sensor comprises a sensor housing, a detector switch having at least first and second alternative positions to indicate that an alarm event is occurring, an electrical cord for providing power to the alarm sensor which power is then directed to the article being monitored through connection to a power output port on the sensor. The voltage emanating from the power output port and directed to the article may be varied by a voltage selection switch positioned on the sensor.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is directed to display alarm sensors and, in particular, a voltage selectable alarm sensor incorporated into a security device for use in theft prevention.
2. Background Art
Product displays in consumer electronic stores often incorporate security systems that simultaneously allow consumers to examine and test fully functioning consumer electronic products without exposing the storeowner to a risk of theft. Such security systems may simply involve attaching a retractable tether from the consumer display to the consumer electronic product. More advanced systems may also incorporate an electronic alarm system that alerts store personnel both visually and audibly in the event the alarm sensor becomes disconnected either from the product or from the product display.
Handheld cameras, camcorders and other smaller electronics are ripe for such retail theft. Because of size and features of such electronics, consumers prefer to handle and manipulate these products prior to purchase, to determine if the features in a particular model of product are suitable for the consumer's intended use. To permit the products to operate, the products are typically powered by some sort of electrical cord—one cord for each product. Moreover, because different products may require different voltages to power the product, many power sources or adapters are often required—one for each product.
Thieves are particularly attracted to stealing handheld cameras and other small electronics because the devices are easily accessible, expensive and portable. In response, storeowners typically attach an electronic alarm sensor along with a tether to the cameras on display typically with one tether attached to each product. The combination of the electrical cords to power the products and the tethers from the alarm sensors create an unsightly and visually unappealing display, often with an exposed maze of wiring.
Prior art alarms sensors have attempted to reduce the number of tethers or cords by powering the products from the alarm sensors instead of from a separate plug or voltage-regulating adapter. However, these systems typically regulate voltage through the use of different electrical cords connecting the alarm sensor to the product. For example if 4 volts were required, a 4-volt adapter cord would be connected from the outlet plug or the sensor to the product. Such arrangements may actually increase the number of electrical cords that a retailer would require. Product manufacturers have unfortunately not standardized the connections, instead using proprietary connections. As such, the retailer would require at least one electrical cord per voltage to be outputted per each special, proprietary connection.
There are other disadvantages to prior art alarm sensors—aside from too many cords creating an unsightly display and the product powering issues. For example, many of these prior art alarm sensors use small light emitting diodes to indicate when an alarm sensor is not attached to a product, i.e. an alarm event. While products are generally portable, the products may still be large enough to visually obscure the light emitting diode.
It would be desirable to provide an alarm sensor that reduces the number of electrical cords and tethers in a display area.
It would also be desirable to provide such an alarm sensor that eliminates the need to inventory many variations of electrical cords to power the varying cameras and other electrical products available.
It would still further be desirable to simplify the installation of an alarm sensor to a product being monitored.
It would also be desirable to provide a means to increase the visibility of the alarm sensor indicating that an alarm event is occurring—in the environment of an efficient, difficult to bypass theft prevention system.
These and other desirable characteristics of the invention will become apparent in view of the following specification and claims.
SUMMARY OF THE INVENTION
The present invention is a voltage selectable alarm sensor for operably mounting an anti-theft device to an article being monitored. The alarm sensor comprises a sensor housing with top and bottom surfaces, where the top surface is adjacent to the article to be monitored when the alarm sensor housing is mounted to the article by a mounting member, a detector switch operably positioned proximate to the top surface of the alarm sensor having at least a first and a second orientation, in which the first orientation indicates that the alarm sensor is operably and properly mounted on the article and the second orientation indicates that the alarm sensor is not operably and properly mounted onto the article so as cause an alarm event; an electrical cord for providing power to the alarm sensor, where the cord also provides for communicating between the alarm sensor and a remote alarm detection unit—towards determining the current orientation of the detector switch and whether, in turn, an alarm event is actually occurring. The electrical cord also provides power to the alarm sensor for further direction to the article being monitored, through a power output port capable of producing and providing electrical current of varying voltages to electrically operate the article where the voltage is selected by a voltage selection switch for selecting a desired electrical voltage, from amongst a plurality of available voltages.
In a preferred embodiment of the invention, the mounting member is a combination of a layer of releasable adhesive applied to the top surface of the sensor housing so as to be sandwiched between the alarm sensor and the article being monitored; and a threaded fastener that extends from the top surface of the sensor housing for mated receipt by a threaded aperture located in the article. The alarm sensor also includes a device for visually determining the orientation of the detector switch as well as a device for visually determining the voltage selected for transmission through the power output port to the article. In this preferred embodiment, the voltage selection switch is a slide switch having at least three predetermined positions for selecting the voltage to be transmitted to the power output port. Connecting the output port to the article is one of a plurality of adapter cords for providing power to the article to permit the article to function. Each of the adapter cords preferably includes one standardized connector for mated connection with the power output port of the sensor housing—and a non-standardized connector for mated connection to the incoming power port of the article.
In another embodiment, the voltage selectable alarm sensor comprises a substantially rectangular housing having a top and a bottom surface, where the top surface is adjacent to the article being monitored when the sensor housing is operably mounted to said article. The sensor housing is mounted to the article by a layer of releasable adhesive applied to the top surface of the sensor housing so as to be sandwiched between the alarm sensor and the article being and further secured by a threaded fastener that extends from the top surface of the sensor housing for mated receipt by a threaded mounting aperture located in the said article. A detector switch is positioned proximate to the top surface of the sensor housing whereby the detector switch likewise has at least a first and a second orientation. The first orientation indicates that the alarm sensor is operably and properly mounted on the article and the second orientation indicates that the alarm sensor is not operably and properly mounted onto the article thereby causing an alarm event. An electrical cord for providing power to the alarm sensor is attached to the sensor. The electrical cord also provides a way for communicating with a remote alarm detection unit towards determining the current orientation of the detector switch and, in turn, whether an alarm event is occurring as well as a way to power not only the alarm sensor but also the article being monitored. The sensor housing preferably includes a power output port capable of producing and providing electrical current of one of at least three predetermined voltages—as transmitted from said electrical cord and a slide switch having at least three predetermined positions for selecting the voltage provided by the power output port to one of at least three predetermined voltages.
In this embodiment, a light emitting diode visually indicates whether that the detector switch is in the first orientation or the second orientation. Preferably, the light emitting diode for visually indicating said orientation of the detector switch is constantly illuminated when the alarm sensor is receiving power through the electrical cord and the detector switch is in the first orientation and intermittently illuminated when the alarm sensor is receiving power and the detector switch is in the second orientation. Likewise the sensor housing includes a set of at least three light emitting diodes each corresponding to one of the at least three predetermined positions of the slide switch and the at least three predetermined voltages, and capable of illumination so as to indicate which of the at least three predetermined voltages is provided by the power output port.
The voltage selectable alarm sensor further includes a plurality of adapter cords, where one of the adapter cords is provided for connecting the power output port to the article input port, thereby providing power to the article to permit said article to function. It is preferable if each of the plurality of adapter cords are configured with a standardized connector on one end for mated connection with the power output port and a non-standard connector on the other end for mated connection with the article.
In another preferred embodiment, a voltage selectable alarm sensor for operably mounting an anti-theft device to an article being monitored, comprises a substantially cylindrical sensor housing including a top and a bottom, where the top end is proximate to the article being monitored when the sensor housing is operably mounted to the article. The alarm sensor is mounted to the article through a mounting member so to engage a detector switch having at least a first and a second orientation, where the first orientation indicates that the alarm sensor is operably and properly mounted on the article and the second orientation indicates that the alarm sensor is not operably and properly mounted onto the article thereby causing an alarm event.
In this embodiment, a substantially circular security indicator ring is provided, having a top and bottom surface and positioned so that the bottom surface is adjacent the top end of said sensor housing at the top end's circumference. The security indicator ring is capable of illumination for visual detection from a range of locations so as to indicate the first and second orientations of the detector switch, which is operably positioned adjacent the indicator ring and the article being monitored. Providing power to the alarm sensor, an electrical cord likewise provides for communicating with a remote alarm detection unit, towards determining the current orientation of the detector switch and, in turn, whether an alarm event is occurring. The electrical cord also provides power to the alarm sensor and the article being monitored. Preferably, the sensor housing also includes a power output port capable of producing and providing electrical current of varying voltages to at least operate the article electrically and a voltage selection switch for selecting a desired voltage from amongst a plurality of available voltages to operate alternative articles of varying voltage demands.
In a further embodiment, the voltage selectable alarm sensor comprises a substantially cylindrical sensor housing having a top and a bottom end, where the top end is proximate to the article being monitored when the sensor housing is operably mounted to the article. The alarm sensor includes a detector switch having at least a first and a second orientation, where the first orientation indicates that the alarm sensor is operably and properly mounted on the article and the second orientation indicates that the alarm sensor is not operably and properly mounted onto the article thereby causing an alarm event. A substantially circular security indicator ring has top and bottom surfaces and is likewise positioned so that the bottom surface is adjacent the top end of the sensor housing at the top end's circumference, where the indicator ring is capable of illumination for visual detection from a range of locations so as to indicate the first and second orientations of the detector switch, which is operably positioned adjacent the indicator ring and the article.
A threaded fastener that extends from proximate the top of the security indicator ring is again used to mount the alarm sensor into a threaded mounting aperture located in the article being monitored. A stabilization peg extends from the top surface of the security indicator ring towards the article for receipt by a recess in the article to prevent rotation of article about the sensor housing. An electrical cord again provides power to the alarm sensor while providing a link to communicate with a remote alarm detection unit, towards determining the current orientation of the detector switch and, in turn, whether an alarm event is occurring. The electrical cord provides power not only to the alarm sensor but also to the article, through a power output port capable of producing and providing electrical current of varying voltages to at least electrically operate the article. Controlling the voltage of the power output port is a voltage selection switch for selecting a desired voltage from amongst a plurality of available voltages adjacent the power output port.
Preferably, the security indicator ring is constantly illuminated when the alarm sensor is receiving power through the electrical cord and the detector switch is in the first orientation and intermittently illuminated when the alarm sensor is receiving power through the electrical cord and the detector switch is in the second orientation. This embodiment also includes a device to visually determining the voltage emanating from the power output port. The voltage outputted is chosen by a slide switch having at least three predetermined positions corresponding to at least three predetermined voltages to be provided by said power output port. The manner of visually determining the voltage emanating from the output port may be at least three light emitting diodes each corresponding to one of the at least three predetermined positions of the slide switch. Preferably, the at least three predetermined positions, voltages and light emitting diodes comprises four predetermined positions, voltages and light emitting diodes.
In this embodiment, an adapter cord for connecting the power output port to the article is included, thereby providing power to the article to permit the article to electrically function. Alternatively, a plurality of adapter cords, may be included, where only one of the adapter cords is for connecting the power output port to the article thereby providing power to the article to permit said article to function. Each of the plurality of adapter cords is configured with a standardized connector for mated connection with the power output port and a non-standard connector for mated connection with the article.
The present invention also includes a method for integrating with an article, a voltage selectable alarm sensor of an anti-theft device comprising the steps of: mounting a sensor housing having top and bottom surfaces, so that the top surface is adjacent the article being monitored when the sensor housing is operably mounted to the article; positioning a detector switch having at least a first and a second orientation proximate the top surface of the alarm sensor so as to be sandwiched between the sensor housing and the article, where the detector switch is in the first orientation to indicate that the alarm sensor is operably and properly mounted on the article and in the second orientation to indicate that the alarm sensor is not operably and properly mounted onto the article thereby causing an alarm event; powering the alarm sensor through an electrical cord towards further powering the article from an output port located on the sensor housing; communicating with a remote alarm detection unit through the electrical cord towards determining the current orientation of the detector switch and whether, in turn, an alarm event is occurring; selecting a voltage at the alarm sensor from a plurality of voltages capable of being transmitted by the output port in the alarm sensor to power the article being monitored; selecting an appropriate adapter cord from amongst multiple adapter cords for at least electrically connecting the alarm sensor to the article; and directing electrical current from the alarm sensor to the article through the adapter cord, to electrically power the article.
Another alternative embodiment of the invention comprises a voltage selectable alarm sensor for operably mounting an anti-theft device to an article being monitored. The alarm sensor comprises a sensor housing and a cap positionable on said housing. The cap has a top surface and a bottom surface opposite thereto, where said top surface is adjacent said article being monitored when said sensor is operably mounted to said article. The sensor also comprises means for releasably mounting said alarm sensor onto said article being monitored, said means for mounting said alarm being accessible only when said cap is separated from said sensor housing. The sensor also comprises a detector switch operably positioned in said sensor housing and having a vertically movable switch member movable between at least first and second positions, in which said first orientation of said detector switch indicates that said cap is operably and properly mounted on said sensor housing and said second orientation of said detector switch indicates that said cap is not operably and properly mounted onto said sensor housing thereby causing an alarm event. An electrical cord provides power to said alarm sensor. The electrical cord also provides a means for communicating with a remote alarm detection unit towards determining the current orientation of said detector switch and whether, in turn, an alarm event is occurring. The electrical cord also provides power to said article being monitored. The sensor housing also includes a power output port capable of producing and providing electrical current of varying selectable voltages to electrically operate a plurality of said articles at a plurality of varying voltages, respectively; and a voltage selection switch for selecting a desired electrical voltage from amongst said plurality of available varying voltages to operate said article.

DETAILED DESCRIPTION OF THE DRAWINGS
While this invention is susceptible of embodiment in many different forms, there are shown in the drawings and will herein be described in detail, several specific embodiments, with the understanding that the present invention is to be considered as an exemplification of the principle's of the invention and is not intended to limit the invention to the embodiments illustrated.
The circuitry of an anti-theft system
10
is schematically illustrated in FIG.
1
. Controlling the system is remote alarm detection unit
13
, which is powered by power supply
14
. While it is shown that alarm detection unit
13
has an external A/C power supply
14
, it is also known in the art to incorporate a power supply into remote alarm detection
13
with unit
13
being powered by battery. While it is possible for voltage selectable alarm sensor
20
to be connected directly to remote alarm detection unit
13
, sensor
20
is connected indirectly to remote alarm detection unit
13
, as shown. In this configuration, remote alarm detection unit
13
is then connected to a junction box sometimes referred to as a hub or splitter
12
.
In this configuration, splitter
12
has its own separate power source
15
, different than power source
14
connected to remote alarm detection unit
13
. Again, as with the remote alarm detection unit
13
, splitter
12
may be powered by either A/C current as shown in
FIG. 1
, or alternatively through a D/C source such as battery. Splitter
12
includes a number of sensor receptors
18
. Sensor receptors
18
are electrical jacks, which receive the matching plug connectors from the end of cord
16
. The connector on the end of cord
16
may be of any type of common plug connector used and known to those skilled in the art, for connecting signal generating appliances. One type of common connector is an RJ11 plug with a matching RJ11 jack within splitter
12
. Alternatively, the connectors may be coaxial cable connectors or RCA type plug connectors.
Again, voltage selectable alarm sensor
20
may be connected directly to splitter
12
at sensor receptor port
18
. However in
FIG. 1
, powered recoiler
11
is connected between voltage selectable alarm sensor
20
and splitter
12
. Powered recoilers are known in the art and are used to provide a method for extending the distance between splitter
12
and alarm sensor
20
when sensor
20
is attached to a portable article being monitored. In particular, cord
16
is connected, or “plugged in to”, sensor receptor port
18
. As shown in
FIG. 1
, cord
16
comprises six (6) wires. Two (2) of those wires carry electrical current, i.e. power, from splitter
12
through and to alarm sensor
20
. Another wire carries an alarm signal, which signal would indicate whether alarm sensor
20
is properly attached to an article being monitored, or alternatively whether an alarm event is occurring. One wire is used by the light emitting diode or LED within sensor
20
, which LED indicates whether sensor
20
is powered. The wires carrying the alarm signal and the LED share a common return wire. The last wire within cord
16
is a common ground. Accordingly, cord
16
carries not only power to the sensor, but also carries alarm signals between the sensor and remote alarm detection unit
13
. Typically, cord
16
is of a fixed length. In contrast, electrical cord
17
is retractable into recoiler
11
so as to provide the necessary length of cord for attaching sensor
20
to an article. Electrical cord
17
carries the same number of wires and electrical signals as that of cord
16
. Electrical cord
17
is then connected to sensor
20
so as to connect, indirectly, sensor
20
to remote alarm detected unit
13
, thereby completing anti-theft device system
10
.
FIGS. 2 through 4
generally show a preferred embodiment of the voltage selectable alarm sensor
20
. Voltage selectable alarm sensor
20
includes a substantially rectangular housing
21
that is mounted onto an article to be monitored against theft, through mounting bolt
23
. As depicted in
FIG. 3
, mounting bolt
23
may be a threaded bolt or screw to be received into the threaded aperture of the article. Of course, other types of mounting means known to those skilled in the art would also be acceptable. For example, instead of a threaded bolt, the bolt may have a tongue-and-groove, or bayonet arrangement with the aperture located in the article. Sensor
20
also contains a layer of releasable adhesive
22
located on the top surface of sensor housing
21
. When sensor
20
is properly mounted onto an article, that article will engage adhesive
22
so as to further restrain sensor
20
to the article. While it is not recommended, it is possible to forego a mounting means such as threaded bolt
23
and simply rely upon the releasable adhesive
22
for mounting sensor
20
onto the article. As it should be appreciated, merely relying upon adhesive
22
is less secure than utilizing both mounting means such as threaded bolt in combination with releasable adhesive
22
.
When sensor
20
is properly mounted to article
60
, the article will engage detector switch
24
. Detector switch
24
is a common microswitch that has at least two different orientations. The first, or unsecured orientation is shown in
FIG. 3
where detector switch
24
extends past a top surface of sensor housing
21
and adhesive layer
22
. In this orientation, sensor
20
transmits a signal to remote alarm detection unit
13
(of
FIG. 1
) that the article being monitored is not properly attached thereby causing an alarm event. An alarm event is an indication that the article attached to the sensor is not completely and properly attached to the sensor and/or that the article may have been subjected to an attempted theft. In either event, an alarm event indicates that the sensor may require attention and possibly some corrective action.
When an article is properly mounted on sensor
20
, detector switch
24
is in a second orientation where switch
24
is substantially even with the top surface of sensor housing
21
. In this orientation, a signal is generated by the sensor and sent to remote alarm detection unit
13
indicating that sensor
20
is operating properly and is properly mounted to the article being monitored. As explained above, and as further shown in
FIGS. 2 through 4
, sensor
20
is powered by electrical cord
17
. In addition to providing power to sensor
20
, electrical cord
17
transmits signals between sensor
20
and remote alarm unit
13
, towards indicating whether an article is secured on sensor
20
or an alarm event may be occurring. Sensor
20
also includes means for indicating whether sensor
20
is receiving power through cord
17
. In this embodiment, light emitting diode (LED)
27
illuminates when sensor
20
receives power through cord
17
. If sensor
20
is properly mounted to the article, then LED
27
illuminates continuously. In contrast, when sensor
20
is receiving power and the article is not properly mounted on sensor
20
, LED
27
only illuminates intermittently, e.g. flashes or blinks, thereby indicating an alarm event. Of course, it is known in the industry that a change in color of an LED may also indicate whether power is being received, or that an alarm event is occurring.
As further shown in
FIGS. 2 through 4
, sensor
20
is also used to transmit power to the article being monitored so that the article may function electrically. Power received from cord
17
is transmitted through sensor
20
and transmitted through power output port
29
. An adapter cord, such as adapter cord
50
in
FIG. 8
, is connected to power output port
29
and then connected to the power input jack of the article being monitored. However, as articles tend to require different voltages to be powered, the voltage transmitted by power output port
29
may be selectively and appropriately limited by sensor
20
. A voltage selection switch that has at least three (3) positions selects the voltage. In the preferred embodiment, the voltage selection switch is a four (4) position slide switch
25
. Slide switch
25
is positioned so as to be accessible from the bottom surface of sensor housing
21
. The voltages transmitted through power output port
29
and selected by switch
25
may be any one of four predetermined voltages, such as 4 volts, 6 volts, 8 volts and 9 volts. These voltages are achieved by “stepping down” the voltage received by sensor
20
through cord
17
, which voltage is typically 12 or 15 volts. In this embodiment, sensor
20
also includes a means for visually indicating the particular, selected voltage being transmitted by power output port
29
. As shown in
FIGS. 2 through 4
, four light emitting diodes
28
are used to indicate which of four voltages is being transmitted. Depending upon which voltage is being transmitted, namely 4, 6, 8 or 9 volts, the appropriate LED would light. Instead of light emitting diodes, other means such as color indicators, or liquid crystal displays may be used to indicate the specific voltage being outputted by power output port
29
.
Another embodiment of the invention is shown in
FIGS. 5 through 8
. Here, alarm sensor
40
has a substantially cylindrical housing
41
, and cap
70
with threaded bolt
42
. Housing
41
and cap
70
may be connected to one another by any suitable means, such as a threaded engagement, forced or snap fit, etc. Power is supplied to sensor
40
through cord
49
, which also transmits signals between sensor
41
and a remote alarm detection unit (not shown). Sensor
40
also includes a security indicator ring
46
. Security indicator ring
46
is a substantially circular, translucent piece of plastic that is positioned proximate to and extending around the circumference of the top of sensor housing
41
. Security indicator ring
46
illuminates to indicate that power is being supplied to sensor
40
. Additionally, security indicator ring
46
may be used to indicate that an alarm event is occurring, as in the prior embodiment, through blinking, flashing or other means known in the art. Because security indicator ring
46
is positioned around the circumference of housing
41
, it is viewable from a wide range of locations, unlike the use of a LED, which may be obscured depending upon the location of the viewer and article, relative to the sensor. It would also be known in the art to indicate an alarm event through a change in color or brightness in the security indicator ring
46
.
Sensor
40
is preferably mounted to the article (such as article
60
) through threaded bolt
42
and releasable adhesive layer
43
. The head of bolt
42
is accessible only when cap
70
and housing
41
are separated. Therefore, article
60
cannot be removed from sensor
40
, once attached, unless cap
70
and housing
41
are separated. Accordingly, to detect the separation of cap
70
from housing
41
, a two-position switch is provided in the interior of housing
41
, which is appropriately connected to the sensor electrical circuitry, such that a change in the state of the switch will indicate a possible theft attempt. The switch, of the type which is generally known to those of ordinary skill in the art (and so the specific details of which are omitted for simplicity of the illustration), will preferably include a vertically moving switch member
45
. Switch member
45
preferably will be movable between an upper position (above the upper edge of housing
41
) and a lower position (shown in
FIG. 5
) and will preferably be biased toward the upper position by any suitable biasing means, such as a coil spring (not shown). When cap
70
is fully positioned down on housing
41
, switch member
45
is pushed down by the underside surface of cap
70
to its lower position (shown in FIG.
5
). As is customary with such switches, switch member
45
will either make or break an electrical connection when moved from the lower position to the upper position, so that the switch will either cause a signal to be sent or interrupted, indicating separation of cap
70
from housing
41
, indicating a possible theft attempt.
Protruding from the top of security indicator ring
46
is stabilization peg
44
. Stabilization peg
44
is received by recessed portion
61
in camera
60
. Inserting stabilization peg
44
into recessed portion
61
prevents camera
60
from being inadvertently rotated about sensor
40
so as to adversely loosen it from threaded bolt
42
thereby indicating an improper alarm event.
Sensor
40
is electrically connected to camera
60
through adapter cord
50
. As shown in
FIG. 6
, adapter cord
60
is plugged into the power output port on the top of security indicator ring
46
and lies in a channel so as to be substantially level with the top of security indicator ring
46
when mounted on camera
60
. The other end of adapter cord
50
is then plugged into the power intake jack of camera
60
as shown in FIG.
8
. As in the other described embodiment, the voltage transmitted through adapter cord
50
may be selected and limited by sensor
40
through selection switch
48
. The selected voltage being transmitted by sensor
40
to camera
60
is then indicated by light emitting diodes
47
, mounted in housing
41
, and visible through aperture openings or, alternatively, windows
65
in cap
70
, as are shown in FIG.
5
.
It is envisioned that adapter cord
50
would have a standardized connection for insertion into power output port of sensor
40
. Unfortunately, camera manufacturers provide their own proprietary power input jacks of differing configuration. Accordingly, the other end of adapter cord
50
that is “plugged” into camera
60
will have to be non-standardized and particular to the camera being powered, and selected from an available “inventory” of connectors all fitting the output jack at the sensor, but with differing article input jacks.
Another embodiment of the invention is shown in
FIGS. 9 through 12
, which is similar to the embodiment of
FIGS. 5-8
, such that similar structural elements are given similar reference numerals augmented by a prime (′). Here, alarm sensor
40
′ has a substantially cylindrical housing
41
′, and cap
70
′ with threaded bolt
42
′. Housing
41
′ and cap
70
′ may be connected to one another by any suitable means, such as a threaded engagement, forced or snap fit, etc. Power is supplied to sensor
40
′ through cord
49
′, which also transmits signals between sensor
41
′ and a remote alarm detection unit (not shown). Sensor
40
′ also includes a security indicator ring
46
′. Security indicator ring
46
′ is a substantially circular, translucent piece of plastic that is positioned proximate to and extending around the circumference of the top of sensor housing
41
′. Security indicator ring
46
′ illuminates to indicate that power is being supplied to sensor
40
′. Additionally, security indicator ring
46
′ may be used to indicate that an alarm event is occurring, as in the prior embodiment, through blinking, flashing or other means known in the art. Because security indicator ring
46
′ is positioned around the circumference of housing
41
′, it is viewable from a wide range of locations, unlike the use of an LED, which may be obscured depending upon the location of the viewer and article, relative to the sensor. It would also be known in the art to indicate an alarm event through a change in color or brightness in the security indicator ring
46
′.
Sensor
40
′ may also be mounted to the article (such as article
60
′) through threaded bolt
42
′ and releasable adhesive layer
43
′. In this alternative embodiment, again, a two-position switch may be provided (the specific details of which are omitted, but which are known to those of ordinary skill in the art), that is suitably connected to the circuitry, such that a change in state of the switch will generate or alter an electrical signal, signifying an attempted tampering with the sensor. In the embodiment of
FIGS. 9-12
, however, the switch is configured to detect an attempted separation of sensor
40
′ from article
60
′. That is, vertically movable switch member
45
′, in its biased upper position, extends through an aperture in cap
70
′. When sensor
40
′ is attached to article
60
′, the bottom of article
60
′ pushes switch member
45
′ down until its upper end is substantially flush with the upper surface of cap
70
′. An attempted forcible separation of article
60
′ from sensor
40
′ will cause switch member
45
′ to be able to move up from its lower position shown in
FIG. 9
, thus causing a change of state, which will cause an electrical connection to be made or broken, resulting in an alert signal.
Protruding from the top of security indicator ring
46
′ is stabilization peg
44
′. Stabilization peg
44
′ is received by recessed portion
61
′ in camera
60
′. Inserting stabilization peg
44
′ into recessed portion
61
′ prevents camera
60
′ from being inadvertently rotated about sensor
40
′ so as to adversely loosen it from threaded bolt
42
′ thereby indicating an improper alarm event.
Sensor
40
′ is electrically connected to camera
60
′ through adapter cord
50
′. As shown in
FIG. 10
, adapter cord
60
′ is plugged into the power output port on the top of security indicator ring
46
′ and lies in a channel so as to be substantially level with the top of security indicator ring
46
′ when mounted on camera
60
′. The other end of adapter cord
50
′ is then plugged into the power intake jack of camera
60
′ as shown in FIG.
12
. As in the other described embodiment, the voltage transmitted through adapter cord
50
′ may be selected and limited by sensor
40
′ through selection switch
48
′. The selected voltage being transmitted by sensor
40
′ to camera
60
′ is then indicated by light emitting diodes
47
′, mounted in housing
41
′, and visible through aperture openings or, alternatively, windows
65
′ in cap
70
′, as are shown in FIG.
9
.
It is envisioned that adapter cord
50
′ would have a standardized connection for insertion into power output port of sensor
40
′. Unfortunately, camera manufacturers provide their own proprietary power input jacks of differing configuration. Accordingly, the other end of adapter cord
50
′ that is “plugged” into camera
60
′ will have to be non-standardized and particular to the camera being powered, and selected from an available “inventory” of connectors all fitting the output jack at the sensor, but with differing article input jacks.
The foregoing description and drawings merely explain and illustrate the invention, and the invention is not limited thereto except insofar as the pending claims are so limited as those skilled in the art who have the disclosure before them will be able to make modifications and variations therein without departing from the scope of the invention.
