The invention is in the field of identification and locator badges.
The invention comprises a locating badge having a housing, an opaque, preferably colored medium, and a transmitting device. At least a portion of the housing is transparent to visible light and at least a portion of the housing is transparent to IR. The housing is also capable of being opened to access the interior, and re-closed via a releasably mechanically engageable feature, preferably a feature such as a snap-lock feature, around at least a portion of the perimeter of at least one housing member. Preferably, the housing comprises at least two housing members, at least one of which is transparent to both visible light and IR.
The opaque medium is disposed within the housing, such that it is visible through the portion of the housing which is transparent to visible light. Preferably, the opaque medium comprises an elastomeric membrane which extends into the area adjacent to the mechanically engageable features, sealing such features to render the housing water resistant. Where “opaque” is used herein, it is intended to cover items with varying levels of opacity, whether the items are semi-transparent or completely opaque.
The transmitting device is situated inside the housing, and oriented such that the IR or visible light transmitted by the device, as applicable, are passed through the transparent portion of the housing.
Optionally, the locating badge incorporating the elastomeric membrane may be provided with additional functionality by the inclusion of a button without sacrificing the water-resistance provided by the elastomeric membrane, because the elastomeric membrane functions as a membrane with an integral electrical contact for a membrane button and also forms a gasket seal around the perimeter of the opening in the housing that is provided to allow access to the button.
One preferred embodiment of the badge 10 as described herein comprises a housing 12, with at least two housing members 14, 16, an opaque member 36, 60 and functional electronic components 20 such as an Infrared (“IR”) or visible light signal transmitter. (
With respect to housing 12, at least a portion of housing 12 is transparent to IR signals and at least a portion of housing 12 is transparent to visible light. Preferably, housing 12 comprises a first housing member 14 and a second housing member 16, with first housing member 14, which defines the front of housing 12, being transparent to IR and visible light. Housing 12 may be made from any materials meeting the above requirements, but is preferably a sturdy, light-weight, durable material to withstand use as an ID and/or locating badge for people or materials in varied environments and conditions. The material is also preferably ductile and elastic enough to avoid breaking or cracking upon frequent handling and potential opening and closing. Certain examples of preferable housing materials include ABS, acrylic, polycarbonate or other materials. Housing 12 may be shaped to be wearable by a person, or to be attached to inventory or goods in any known manner.
Preferably, first housing member 14 comprises a generally rectangular transparent front surface 22 and four side walls 24 extending backwards from the front surface 22 defining an open plane therebetween and second housing member 16 comprises a generally rectangular back surface 26 and four side walls 28 extending forward from the back surface 26 (
Side walls 24 of first member 14 and side walls 28 of second member 16 are preferably engageable with each other via a “snap-lock” engagement. (
It is contemplated that the snap-lock engagement would not be required to extend around the entire perimeter of badge 10. For example, one side of the perimeter could incorporate a hinge between first and second housing members 14, 16, with the remaining portion of the perimeter engageable via a snap lock feature.
Alternatively, or in addition to the snap lock functionality, a security screw or other security feature can be used on the housing, to inhibit unauthorized access to the interior of housing 12. This type of security feature may be desired when the badge 10 incorporates identification information in addition to the locating function.
In the preferred embodiment, an elastomeric membrane 36 is provided between first and second housing members 14, 16. Elastomeric membrane 36 is shaped to fit within the interior contours of the front surface 22, with a front wall 37 located against transparent front wall 22 of front housing member 14, and edges 38 extending toward back surface 26 and then radially outward into the space between side walls 24 of first member 14 and the interior of back surface 26 or a shaped portion of side wall 28 of second member 16. Elastomeric membrane 36 is preferably compressed between the distal end of side walls 24 of first member 14 and the interior of back surface 26 or a shaped portion of side wall 28 of second member 16. Elastomeric membrane 36 may optionally have a thicker bead 40 around its edge 38, and first and second members 14, 16 may have shaped notches or grooves 42 shaped to receive bead 40, to assist in retaining elastomeric membrane 36 between them to provide moisture resistance.
The back side of elastomeric membrane 36 and the interior side of back surface 26 define a cavity in the housing 12 wherein the functional electronic components 20, such as the IR transmitter can be housed. To provide a location to anchor IR signal transmitter 20, interior housing notches or other shaped features 50 may be provided to stabilize or mechanically engage electronic components 20. (
The snap lock engagement, when combined with elastomeric membrane 36, renders housing 12 largely water resistant, and therefore more durable for use in certain environments where splashes or certain amounts of liquids or fluids may be encountered. The mechanical engagement may also permit housing 12 to be opened and assembled by an operator without the use of specialized tools, if desired.
Elastomeric membrane 36 is preferably semi-transparent or opaque, and may be provided in multiple colors to fit a particular housing 12, so that the locating badge 10 (due to the visibly transparent portions of housing 12) can be color-coded, and the color of a particular badge 10 can be altered, even in the field, by opening housing 12, changing elastomeric membrane 36, and closing housing 12, all preferably achievable without the use of specialized tools.
Additionally, one or more buttons 54 may be provided on badge 10. Buttons 54 may be formed by providing an opening 56 in housing 12, and locating a membrane button component 58 below opening 56 and behind elastomeric membrane 36, and embossing or otherwise providing integrated electrical contacts on the back side of the elastomeric membrane 36, such that when button 54 is depressed, the electrical contacts on the back side of elastomeric membrane 36 are forced into contact with membrane button component 58. (
For water resistance, particularly when a button 54 is not provided on badge 10, the sealing portion of elastomeric membrane 36 may be all that is required.
Further identification functionality may be provided for badge 10 by inserting an identification means 60 between elastomeric membrane 36 and the back side of front surface 22, by attaching an identification means 60 to the front side of front surface 22, or by printing identification means 60 on the surface of elastomeric membrane 36, or using any other method of printing, embossing, stamping or marking identification means 60 such that identification means 60 is visible through the portion of housing 12 which is transparent to visible light. (
Since elastomeric membrane 36 or any other opaque material such as identification means 60, are visible through the transparent front wall 22 of housing 12, and housing 12 can be opened and resealed without damage, locating badges 10 can easily be color-coded or display other information from a protected location within housing 12, and the color or information displayed by a particular badge 10 can be changed or modified without purchasing a replacement badge 10 or replacing any of the electronic components 48 therein.
Of course it is understood that the above is a description of preferred embodiments, and that various changes and alterations can be made to badge 10 without departing from the spirit and broader aspects of the invention.
