Abstract
The present invention relates to an improved automated paper dispensing system for dispensing paper products in a restroom stall. The system provides a dispenser having a sensor for activation by a user and a signal emitter integrated therewith. The dispenser is arranged to both store a supply of paper products and automatically dispense, when the sensor is activated by the user, a portion of the supply of paper products. A transceiver is in communication with the signal emitter to receive a signal from the signal emitter when the supply of paper products is low in the dispenser.
The system also provides a micro-controller in communication with each of the transceiver and an electric strike mechanism so that, when the transceiver receives the signal from the at signal emitter that the supply of paper products is low in the dispenser, the transceiver transmits a signal to the micro-controller indicating the low product status, and a further locking instruction signal to the micro-controller. The monitor then is operably able to selectively transmit a locking signal to the electric strike mechanism to lock the door to the restroom stall until the supply of paper products is replenished in the dispenser.
The system also provides a micro-controller in communication with each of the transceiver and an electric strike mechanism so that, when the transceiver receives the signal from the at signal emitter that the supply of paper products is low in the dispenser, the transceiver transmits a signal to the micro-controller indicating the low product status, and a further locking instruction signal to the micro-controller.

Description
AUTOMATED PAPER DISPENSER SYSTEM
FIELD OF THE INVENTION
The present invention relates generally to an automated "hands free" toilet paper dispenser system, thereby reducing the spread of germs and contagions, and which, through use of a sensor, sends a signal informing an operator when the toilet roll is running low, and, if the toilet roll runs out, automatically locks the bathroom door and illuminates a sign to visitors indicating that the washroom is currently unavailable for use.
DESCRIPTION OF THE PRIOR ART
Automated, hands-free paper towel dispensers are known and are a preferred way of dispensing paper towel or toilet paper in a commercial setting, since waste is generally less than with conventional dispensers and the potential for contamination is greatly reduced. In conventional applications, some paper dispensers provide paper when a user pushes a button on the dispenser. For example, Canadian Patent Application No. 2,560,441 (Friesen) discloses a toilet paper dispenser that is operable both in an automatic dispensing mode and a manual dispensing mode.
However, the use of these types of dispensers by a user can cause contamination (though microbes and/or bacteria) on the user's hands and therefore unsanitary conditions can arise. Furthermore, with these types of dispensers, it is not uncommon for these to contain perforated paper in their containers, rather than having a tissue paper end which can be grasped by the user, wherein the restroom user has to reach inside the dispenser and pull the paper outwardly, which increases the possibility of a user's hands coming into contact with bacterial growth.
Other types of dispensers utilize a proximity sensor within or around the housing to detect a presence of a user's hand at a predetermined location near the dispenser, which causes a quantity of sheet product to be dispensed therethrough. Such touch-less dispensing also permits ease in dispensing for those individuals with arthritis or other afflictions that would make mechanical dispensing difficult. Additionally, touch-less dispensing permits ease in dispensing for those individuals with paint, grease or other substances on their hands. However, while such types of dispensers are more hygienic than manually activated dispensers, these types of dispensers, when the tissue roll runs out, can still permit entry of users into the bathroom stall, and, furthermore, do not provide an indication to a user that the bathroom stall has an inadequate supply of toilet paper or tissue product before a user enters the stall. Accordingly, there is a need for an improved automated "hands free" toilet paper dispenser, which, through use of a sensor, sends a signal informing an operator or attendant when the toilet roll is running low, and, if the toilet roll runs out, automatically locks the bathroom door and illuminates a sign to visitors indicating that the washroom is currently unavailable for use. Moreover, it is advantageous to provide such a system for reducing the spread of germs and contagions. To this end, the present invention effectively addresses this need.
SUMMARY OF THE INVENTION
A general object and advantage of the present invention is to provide an improved automated "hands free" toilet paper dispenser, which allows users to dispense tissue or toilet paper products without touching the dispenser, thereby reducing the spread of germs and contagions, and which sends a signal to a remote location informing an operator or attendant when the toilet paper or tissue roll in a particular rest room stall is running low.
A still further object and advantage of the present invention is to provide an improved automated "hands free" toilet paper dispenser which, if the toilet paper or tissue roll runs out, is able to automatically lock the bathroom door and illuminates a sign to new visitors indicating that the washroom is currently unavailable for use.
According to one aspect of the present invention, there is provided an automated paper dispensing system for dispensing paper products in a restroom stall, the system comprising a dispenser having a sensor for activation by a user and at least one signal emitter integrated therewith, the dispenser being arranged to both store a supply of the paper products and automatically dispense, when the sensor is activated by the user, at least a portion of the supply of the paper products; a transceiver in communication with the at least one signal emitter, the transceiver being adapted to receive a signal from the at least one signal emitter when the supply of the paper products is low or has run out in the dispenser; an electric strike mechanism for locking and unlocking the door to the restroom stall; a monitor in communication with the transceiver, wherein, when the transceiver receives the signal from the at least one signal emitter that the supply of the paper products is low in the dispenser, the transceiver transmits a signal to the monitor to indicate a low paper product status be communicated to the monitor; and a micro-controller in communication with each of the transceiver and the electric strike mechanism, wherein, when the transceiver receives the signal from the at least one signal emitter that the supply of the paper products is low or has run out in the dispenser, the transceiver further transmits a signal to the micro-controller, whereby the micro-controller is operably able to selectively transmit a locking signal to the electric strike mechanism to lock the door to the restroom stall.

BRIEF DESCRIPTION OF THE DRAWINGS
A preferred embodiment of the present invention is described below with reference to the accompanying drawings, in which:
Figure 1 illustrates a front view of the automated "hands free" toilet paper dispenser system of the present invention;
Figure 2 illustrates the automated "hands free" toilet paper dispenser system of the present invention, illustrating the interior of a rest room; and Figure 3 illustrates an embodiment of the monitor of the present invention.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The present invention provides an improved automated "hands free" toilet paper dispenser system, which, through use of a sensor, sends a signal informing an operator when the toilet roll is running low, and, if the toilet paper product runs out, automatically locks the restroom door, and illuminates a sign to visitors indicating that the washroom is currently unavailable for use, until the supply of paper products is replenished in the dispenser.
As shown in Figure 2, which illustrates the interior of a restroom 1, it can be seen that the automated "hands free" toilet paper dispenser system to be utilized in conjunction with a restroom 1 comprises an automated dispenser 9 having a sensor 2 for activation by a user and a signal emitter (not shown) integrated therewith. The dispenser 9, of course, is arranged to both store a supply of toilet paper products (not shown) therein and automatically dispense, when the sensor 2 is activated by a user of the restroom 1, a portion of the supply of the paper products. In this manner, the dispenser of the present invention provides a "hands free" toilet paper dispenser.
The dispenser 9 also provides, in a preferred embodiment, LED indicators for providing visual indicators. In Figure 2, these LED indicators are a low battery indicator 6, and a low paper product indicator 8. Power for the dispenser 9 can be provided by a power source (not shown) such as, for example, a battery source or through electrical wiring, or through other means, as would be apparent to one skilled in the art.
A transceiver 4 communicates, preferably electronically, with the signal emitter of the dispenser 9. In a preferred embodiment, the transceiver 4 is an RF transceiver that is mounted integrally with the dispenser 9, though it will be understood that variations to this are possible. Power for the transceiver can be provided either through the power source which provides power to the dispenser 9, or, when it is connected remotely from the dispenser 9, through its own power source.
For example, this could be effected by a battery source or through electrical wiring. In a preferred embodiment, the transceiver 4 is adapted to receive a signal from the signal emitter when the supply of paper products is low in the dispenser. Once this signal has been received from the signal emitter, the transceiver 4 transmits a signal to the monitor 21, as seen in Figure 3, to remotely indicate the status of toilet paper dispenser.
The monitor 21 is the main indication panel for the system of the present invention.
Preferably, the monitor is a microprocessor (or, in another embodiment, a touch screen display), and is powered by a battery, or through electrical wiring, or through other means, as would be apparent to one skilled in the art. In use, the monitor 21 is used to data log events, such a low paper product status, as they occur in the restroom. In a preferred embodiment, these events can be web or cell accessible. The monitor 21 can indicate the low paper products status via text indication 23, lights (not shown), audible buzzer 27 or any combination of these. In a preferred embodiment, the monitor 21 will have a snooze button 29 thereon, which can disable the audible buzzer 27 for a period of time, it being understood that the duration length can be varied. In addition, the monitor 21 may be a portable device which can be carried by personnel, or in alternative embodiments, may be desk or wall mounted. Monitor 21 will also have a low battery indicator 31, and a low paper product indicator 33. While, in a preferred embodiment, the monitor 21 is in electronic communication with the transceiver 4 and is used to data log events, such as low paper product status, as they occur in the restroom, it should be noted that, in an alternative embodiment, the monitor 21 can be in electronic communication with each of the other components of the system, which include the transceiver 4, the electric strike mechanism 15, Occupied Light Sign 3, Vacant Light Sign 5, and touch-less sensors 7, 19, as hereinafter described. It will be appreciated by those skilled in the art that the monitor 21, or any other of the components of this system, can communicate with each other through the use of wires, fiber optics, electro magnetic signals, or a combination thereof, as is conventionally known.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The present invention provides an improved automated "hands free" toilet paper dispenser system, which, through use of a sensor, sends a signal informing an operator when the toilet roll is running low, and, if the toilet paper product runs out, automatically locks the restroom door, and illuminates a sign to visitors indicating that the washroom is currently unavailable for use, until the supply of paper products is replenished in the dispenser.
As shown in Figure 2, which illustrates the interior of a restroom 1, it can be seen that the automated "hands free" toilet paper dispenser system to be utilized in conjunction with a restroom 1 comprises an automated dispenser 9 having a sensor 2 for activation by a user and a signal emitter (not shown) integrated therewith.

In this manner, the dispenser of the present invention provides a "hands free" toilet paper dispenser.
The dispenser 9 also provides, in a preferred embodiment, LED indicators for providing visual indicators. In Figure 2, these LED indicators are a low battery indicator 6, and a low paper product indicator 8. Power for the dispenser 9 can be provided by a power source (not shown) such as, for example, a battery source or through electrical wiring, or through other means, as would be apparent to one skilled in the art.
A transceiver 4 communicates, preferably electronically, with the signal emitter of the dispenser 9. In a preferred embodiment, the transceiver 4 is an RF transceiver that is mounted integrally with the dispenser 9, though it will be understood that variations to this are possible. Power for the transceiver can be provided either through the power source which provides power to the dispenser 9, or, when it is connected remotely from the dispenser 9, through its own power source.
For example, this could be effected by a battery source or through electrical wiring. In a preferred embodiment, the transceiver 4 is adapted to receive a signal from the signal emitter when the supply of paper products is low in the dispenser. Once this signal has been received from the signal emitter, the transceiver 4 transmits a signal to the monitor 21, as seen in Figure 3, to remotely indicate the status of toilet paper dispenser.
The monitor 21 is the main indication panel for the system of the present invention.
Preferably, the monitor is a microprocessor (or, in another embodiment, a touch screen display), and is powered by a battery, or through electrical wiring, or through other means, as would be apparent to one skilled in the art. In use, the monitor 21 is used to data log events, such a low paper product status, as they occur in the restroom. In a preferred embodiment, these events can be web or cell accessible.

In addition, the monitor 21 may be a portable device which can be carried by personnel, or in alternative embodiments, may be desk or wall mounted. Monitor 21 will also have a low battery indicator 31, and a low paper product indicator 33. While, in a preferred embodiment, the monitor 21 is in electronic communication with the transceiver 4 and is used to data log events, such as low paper product status, as they occur in the restroom, it should be noted that, in an alternative embodiment, the monitor 21 can be in electronic communication with each of the other components of the system, which include the transceiver 4, the electric strike mechanism 15, Occupied Light Sign 3, Vacant Light Sign 5, and touch-less sensors 7, 19, as hereinafter described. It will be appreciated by those skilled in the art that the monitor 21, or any other of the components of this system, can communicate with each other through the use of wires, fiber optics, electro magnetic signals, or a combination thereof, as is conventionally known.
It will also be appreciated by those skilled in the art that the electro magnetic signals can include infra-red, RF, or any other electro magnetic signal, as are well known in the art.
In operation In a preferred embodiment, a visitor to the restroom approaches the exterior of the restroom 1, as seen in Figure 1, whereby the visitor can determine whether or not the restroom is in use by referring to the Occupied Light Sign 3 and Vacant Light Sign 5.
If the Vacant Light Sign 5 is on, the visitor can approach the door to activate a touchless sensor 7 (or wave his/her hand over the touchless sensor) which transmits a signal to a micro-controller 30, as seen in Figure 1, which in turn instructs the Automatic Operator 11 (seen in Figure 2) to open the door, the Automatic Operator 11 being a door opener of the type commonly known and readily available in the art for automated operation of a door. As illustrated in Figure 2, the Automatic Operator 11 is preferably mounted within an upper portion or header for a door 12. This allows the visitor to enter the restroom and after a brief time delay, the door closes automatically. In another embodiment, the system of the present invention could also operate in a manual manner, wherein a user would open the door using a conventional door handle 14, and the system would forego the use of Automatic operator 11 and touchless sensor 7 to automatically open the door.
Preferably, the touchless sensor 7 is located on an exterior of the restroom.
It will also be understood that a variety of other hands-free actuating or switching devices commonly available in the art may be suited for use in this application other than the one directed for the preferred embodiment, providing each operates without the necessity of hand engagement.
As an example, foot actuators could also be utilized. Of course, it will also be understood that more than one touchless plate could also be used.
Once inside the restroom, as can be seen in Figure 2, a user can utilize dispenser 9, through activation of sensor 2, for dispensing paper products. When the supply of paper products in the dispenser 9 becomes low or runs out (which results in the low paper product indicator 8 becoming lit), the signal emitter (not shown) of the dispenser sends a signal to the transceiver 4, which transmits the status of the toilet paper dispenser remotely to the monitor 21 for display to an attendant. Such remote display to the monitor provides time and notice to the attendant to replenish the supply of paper products in the dispenser 9. When the supply of paper products in the dispenser 9 has run out, the signal emitter (not shown) of the dispenser sends a signal to the transceiver 4, which transmits the status of the toilet paper dispenser to be displayed on the monitor 21, and also transmits a locking instruction signal to a micro-controller 30, it being understood that the locking signal is a programmable option. The micro-controller 30 then instructs the electric locking mechanism 15 to lock, and remain in the locked position, once the visitor has left the restroom, whereby the restroom stall can remain locked an out of use until the supply of paper products in the dispenser has been replenished. In a preferred embodiment, the micro-controller 30 is a microprocessor, as is well known in the art, and is powered by a battery, or through electrical wiring, or through other means, as would be apparent to one skilled in the art.
The micro-controller 30 then removes power from the Vacant Light Sign 5 and applies power to the Occupied Light 3 to be visible for persons outside the restroom, shown in Figure 2. From the exterior of the restroom, the Occupied Light 3 tells new visitors the restroom is not available for use.
In a still further embodiment, an enunciator (not shown), and which are well known in the art, could also be utilized to provide an auditory message to tell new visitors the restroom is not available for use.
After the supply of the paper products in the dispenser 9 has been replenished the micro-controller 30 is operably able to transmit an unlocking signal to the electric strike mechanism 15 to unlock the door to the restroom stall. The micro-controller 30 then removes power from the Occupied Light 3 and applies power to the Vacant Light Sign 5 to be visible for persons outside the restroom, shown in Figure 2. From the exterior of the restroom, the Vacant Light Sign 5 tells new visitors the restroom is again available for use. It will, of course, be understood that the operator can over-ride the door locking signal either locally or remotely in order to access the stall and change the paper products.
In operation In a preferred embodiment, a visitor to the restroom approaches the exterior of the restroom 1, as seen in Figure 1, whereby the visitor can determine whether or not the restroom is in use by referring to the Occupied Light Sign 3 and Vacant Light Sign 5.
If the Vacant Light Sign 5 is on, the visitor can approach the door to activate a touchless sensor 7 (or wave his/her hand over the touchless sensor) which transmits a signal to a micro-controller 30, as seen in Figure 1, which in turn instructs the Automatic Operator 11 (seen in Figure 2) to open the door, the Automatic Operator 11 being a door opener of the type commonly known and readily available in the art for automated operation of a door. As illustrated in Figure 2, the Automatic Operator 11 is preferably mounted within an upper portion or header for a door 12. This allows the visitor to enter the restroom and after a brief time delay, the door closes automatically. In another embodiment, the system of the present invention could also operate in a manual manner, wherein a user would open the door using a conventional door handle 14, and the system would forego the use of Automatic operator 11 and touchless sensor 7 to automatically open the door.
Preferably, the touchless sensor 7 is located on an exterior of the restroom.
It will also be understood that a variety of other hands-free actuating or switching devices commonly available in the art may be suited for use in this application other than the one directed for the preferred embodiment, providing each operates without the necessity of hand engagement.

Once inside the restroom, as can be seen in Figure 2, a user can utilize dispenser 9, through activation of sensor 2, for dispensing paper products. When the supply of paper products in the dispenser 9 becomes low or runs out (which results in the low paper product indicator 8 becoming lit), the signal emitter (not shown) of the dispenser sends a signal to the transceiver 4, which transmits the status of the toilet paper dispenser remotely to the monitor 21 for display to an attendant. Such remote display to the monitor provides time and notice to the attendant to replenish the supply of paper products in the dispenser 9. When the supply of paper products in the dispenser 9 has run out, the signal emitter (not shown) of the dispenser sends a signal to the transceiver 4, which transmits the status of the toilet paper dispenser to be displayed on the monitor 21, and also transmits a locking instruction signal to a micro-controller 30, it being understood that the locking signal is a programmable option. The micro-controller 30 then instructs the electric locking mechanism 15 to lock, and remain in the locked position, once the visitor has left the restroom, whereby the restroom stall can remain locked an out of use until the supply of paper products in the dispenser has been replenished. In a preferred embodiment, the micro-controller 30 is a microprocessor, as is well known in the art, and is powered by a battery, or through electrical wiring, or through other means, as would be apparent to one skilled in the art.
The micro-controller 30 then removes power from the Vacant Light Sign 5 and applies power to the Occupied Light 3 to be visible for persons outside the restroom, shown in Figure 2. From the exterior of the restroom, the Occupied Light 3 tells new visitors the restroom is not available for use.
In a still further embodiment, an enunciator (not shown), and which are well known in the art, could also be utilized to provide an auditory message to tell new visitors the restroom is not available for use.
After the supply of the paper products in the dispenser 9 has been replenished the micro-controller 30 is operably able to transmit an unlocking signal to the electric strike mechanism 15 to unlock the door to the restroom stall. The micro-controller 30 then removes power from the Occupied Light 3 and applies power to the Vacant Light Sign 5 to be visible for persons outside the restroom, shown in Figure 2. From the exterior of the restroom, the Vacant Light Sign 5 tells new visitors the restroom is again available for use. It will, of course, be understood that the operator can over-ride the door locking signal either locally or remotely in order to access the stall and change the paper products.
When the visitor is ready to leave the restroom, he/she waves a hand over a second Touchless Plate 19 on the restroom interior, which transmits a signal to the micro-controller 30 to unlock the Electric locking mechanism 15 and activates the Automatic Door opener 11 to open the door and permit exit.
After a timed delay, the door 12 closes. This sends a signal to the micro-controller 30, as seen in Figure 1 which removes power from the Occupied Light 3 and applies power to the Vacant Light Sign 5. This tells new visitors the restroom is now vacant. In this manner, the Automated Paper Dispensing System of the present invention has now been reset and is ready for the next visitor.
In an alternative embodiment of the operation of the present invention, as indicated previously, the monitor 21 can be in electronic communication with each of the other components of the system. In this embodiment, a visitor to the restroom approaches the exterior of the restroom 1, as seen in Figure 1, whereby the visitor can determine whether or not the restroom is in use by referring to the Occupied Light Sign 3 and Vacant Light Sign 5.
If the Vacant Light Sign 5 is on, the visitor waves his/her hand over a touchless sensor 7 which transmits a signal to the monitor 21 (shown in Figure 3), which in turn instructs the Automatic Operator 11 (seen in Figure 2) to open the door, the Automatic Operator 11 being a door opener of the type commonly known and readily available in the art for automated operation of a door. As illustrated in Figure 2, the Automatic Operator 11 is preferably mounted within an upper portion or header for a door 12. This allows the visitor to enter the restroom and after a brief time delay, the door closes automatically. Alternatively, as noted previously, the system of the present invention could also operate in a manual manner, wherein a user would open the door using a conventional door handle 14, and the system would forego the use of Automatic operator 11 and touchless sensor 7 to automatically open the door. Preferably, the touchless sensor 7 is located on an exterior of the restroom.
After a timed delay, the door 12 closes. This sends a signal to the micro-controller 30, as seen in Figure 1 which removes power from the Occupied Light 3 and applies power to the Vacant Light Sign 5. This tells new visitors the restroom is now vacant. In this manner, the Automated Paper Dispensing System of the present invention has now been reset and is ready for the next visitor.
In an alternative embodiment of the operation of the present invention, as indicated previously, the monitor 21 can be in electronic communication with each of the other components of the system. In this embodiment, a visitor to the restroom approaches the exterior of the restroom 1, as seen in Figure 1, whereby the visitor can determine whether or not the restroom is in use by referring to the Occupied Light Sign 3 and Vacant Light Sign 5.
If the Vacant Light Sign 5 is on, the visitor waves his/her hand over a touchless sensor 7 which transmits a signal to the monitor 21 (shown in Figure 3), which in turn instructs the Automatic Operator 11 (seen in Figure 2) to open the door, the Automatic Operator 11 being a door opener of the type commonly known and readily available in the art for automated operation of a door. As illustrated in Figure 2, the Automatic Operator 11 is preferably mounted within an upper portion or header for a door 12. This allows the visitor to enter the restroom and after a brief time delay, the door closes automatically. Alternatively, as noted previously, the system of the present invention could also operate in a manual manner, wherein a user would open the door using a conventional door handle 14, and the system would forego the use of Automatic operator 11 and touchless sensor 7 to automatically open the door. Preferably, the touchless sensor 7 is located on an exterior of the restroom.
Once inside the restroom, as can be seen in Figure 2, a user can utilize dispenser 9, through activation of sensor 2, for dispensing paper products. When the supply of paper products in the dispenser 9 becomes low or runs out (which results in the low paper product indicator 8 becoming lit), the signal emitter (not shown) of the dispenser sends a signal to the transceiver 4, which transmits the status of the toilet paper dispenser to the monitor 21. Through the monitor 21, the operator or restroom attendant can provide a locking instruction for the restroom, once the visitor has left the restroom, whereby the restroom stall can remain locked an out of use until the supply of paper products in the dispenser has been replenished. In doing this, monitor 21 sends a locking signal to the electric locking mechanism 15 to lock, and remain in the locked position.
Of course, it will be understood that the monitor optionally transmits this locking signal to the electric strike mechanism at a discretion of a restroom attendant. In a still further embodiment, the micro-controller 30 can also be utilized to instruct the electric locking mechanism 15 to lock, in addition to (and separately from) the monitor 21. In this embodiment, micro-controller 30 would also be in electronic communication with the other components of the system and could be manually activated at the restroom door to provide the locking signal. This embodiment could be utilized, in situations where the monitor 21 is a portable device which is not at hand, or has been removed, and manual activation of the micro-controller 30 is required for a locking signal to be sent to the electric locking mechanism 15 to lock the restroom stall until paper product supply has been replenished. Such manual activation of the micro-controller 30 could be effected through use of an entered code key, activation key switch, or through other means which would be apparent to one skilled in the art.
The monitor 21 then removes power from the Vacant Light Sign 5 and applies power to the Occupied Light 3 to be visible for persons outside the restroom, shown in Figure 2. From the exterior of the restroom, the Occupied Light 3 tells new visitors the restroom is not available for use.
After the supply of the paper products in the dispenser 9 has been replenished the monitor 21 is operably able to transmit an unlocking signal to the electric strike mechanism 15 to unlock the door to the restroom stall. The monitor 21 then removes power from the Occupied Light 3 and applies power to the Vacant Light Sign 5 to be visible for persons outside the restroom, shown in Figure 2. From the exterior of the restroom, the Vacant Light Sign 5 tells new visitors the restroom is again available for use. Again, this unlocking signal could be provided by manual use of the micro-controller 30 on the door, as previously described.
When the visitor is ready to leave the restroom, he/she waves a hand over a second Touchless Plate 19 on the restroom interior, which transmits a signal to the monitor 21 to unlock the Electric locking mechanism 15 and activates the Automatic Door opener 11 to open the door and permit exit.
After a timed delay, the door 12 closes. This sends a signal to the monitor 21 which removes power from the Occupied Light 3 and applies power to the Vacant Light Sign 5.
This tells new visitors the restroom is now vacant. In this manner, the Automated Paper Dispensing System of the present invention has now been reset.
The present invention has been described herein with regard to preferred embodiments.
However, it will be obvious to persons skilled in the art that a number of variations and modifications can be made without departing from the scope of the invention as described herein.
