  • the cartridge assembly 200 includes an annular cartridge casing 210 and a film bag 220 initially coiled substantially within the casing 210.
  • the exemplary film bag 220 has one open upper end and a closed lower end.
  • the casing 210 is an annular hollow member with an opening along a lower inside edge through which the closed end of the film bag extends.
  • the apparatus 11 includes a bag constriction element 130 formed as a radially protruding flange.
  • the constriction element 130 is generally disposed below the casing 210 and extends horizontally toward the center of the apparatus 11. The constriction element 130 encourages the film bag 220 to bunch-up and form a bottleneck before hanging down into the inside chamber.
  • the bunched-up bottleneck in the film bag 220 can be more easily twisted, to facilitate the creation of separate sealed compartments between continuous portions of the same film bag 220.
  • the lowest portion of the film bag 220 will hang down past the constriction element 130 toward the container chamber 150.
  • a bottom edge or corner of the film bag 220 can be tethered or attached to an inside of the container inside chamber 150. In this way, the film bag that is attached to the inside of the chamber 150 can not rotate or is limited in how much it can rotate, while the cartridge assembly 200 above is made to rotate as described herein.
  • the constriction member 130 can be a semi-rigid element with sufficient bending resistance to generally hold the configuration shown in FIGS. 5a - 5d. However, the constriction member 130 should also be sufficiently yielding to allow deposited waste to be pushed through the constriction member 130 toward the lower part of the bag 220. While the constriction member 130 can be formed by a set of radially protruding fingers, it can alternatively be formed by a retractable mechanism, such as a set of retractable jaws. When waste is being deposited in the bag 220, through the center of the cartridge assembly 220, the waste is pushed past the constriction member. If the constriction member 220 is alternatively more rigid and not yielding, it can be made to mechanically retract and thus allow waste to be deposited within a segment of the film bag 220 just below the constriction member 130.
  • FIG. 5b As waste is deposited within the film bag 220, an initially deployed segment of bag will get filled, or at least partially filled, as shown in FIG. 5b.
  • the ballooned segments of the bag, as shown in FIGS. 5b-5d represent filled or partially filled segments of bag.
  • the rotational drive mechanism 145 will rotate the cartridge assembly 200 relative to the container 101. With a lower segment of the film bag 220 held or otherwise kept from also rotating, a twist will form in the bottleneck portion of the bag. In this way, a first segment of the film bag containing waste forms a first bag debris cavity 222, which hangs down below the constriction member 130.
  • the drive mechanism 145 With at least one complete rotation, the drive mechanism 145 will twist the bag enough to seal-off the first bag debris cavity 222 from the upper region where the cartridge assembly resides. However, it should be understood that 2-3 complete revolutions of the cartridge relative to the film bag would generally ensure a better sealing-off of compartments of the film bag. The number of revolutions needed to seal-off compartments can be dependent upon the type of material used for the film bags 220. Thereafter, opening the lid 111 and inserting more debris will deploy more film bag from the casing 210 and form a second debris cavity 224, such as that shown in FIG. 5c.
  • the lid can be closed, the cartridge assembly 200 twisted by the drive mechanism 145, with the lower film bag portions held in place, to thereby seal off the second bag debris cavity 224 from the cartridge assembly above.
  • This procedure can be repeated to make third, fourth, or additional debris bag cavities depending on the volumes of the cavities created, the side of the inside chamber 150 and the length of the debris bag 220.
  • the rotation of the cartridge assembly 200 can be performed as an automatic process upon the occurrence of a designated event.
  • the lid 110, 111 could automatically close after a set period and then the drive mechanism 145 actuated to rotate the cartridge assembly 200.
  • a user making deposits could press a button or communicate to the apparatus 10, 11, in some way to initiate the lid closing and cartridge rotation.
  • the apparatus 10, 11 can include an alternative mode that when activated signals the apparatus 10, 11 that the cartridge should not be twisted once the lit is closed. This can be used when syringes are inserted in the film bag.
  • an override mechanism could be provided to alter other default settings or operations of the apparatus 10, 11.
  • the final part of the film bag 220 to be deployed from the casing 210 is the open top end 221 of the bag.
  • that film bag open end 221 comes out of the cartridge casing 210, so the bag 220 can be sealed shut.
  • the film bag 220 is initially secured to a film support member 240, which is an annular ring, when it is newly installed inside the casing 210. But eventually, in order for the entire the film bag 220 to be deployed from the casing 210, the bag must be separated (i.e., pulled free) from the film support member 240. Thus, once the entire film bag 220 is deployed, the film support member 240 remains inside the cartridge casing 210.
  • the film bag top 221 can include a sealing feature 225 so that the overall film bag can be sealed shut and removed from the container 111. As shown in FIG. 5d, the final debris cavity 226 just before the top of the bag could remain empty or only partially filled in order to make it easier to seal the bag shut. It should be understood that while the top of the film bag 221 with the sealing feature 225 is shown in FIG. 5d as pulled down below the constriction member 130, it could have been sealed prior to being pulled through the constriction member 130. In this way, just after being pulled out of an inner portion of the film casing 210, the sealing feature can be activated either automatically or manually, before it drops or is pushed down below the constriction member 130, into the chamber 150 below.
  • the apparatus can initiate a signal that indicates the bag 220 must be sealed, removed and replaced.
  • a more manual alternative could include a color change or striping around the top of the bag 221 to signal to a user that the bag has/is run/running out, needs to be sealed and replaced.
  • a user such as maintenance personnel, could then use the sealing feature 225 to seal off the bag and push it down into the lower chamber 150.
  • the sealing feature 225 could be something like a Ziploc ® bag or other similar bag sealing technologies.
  • the bag sealing feature 225 could be formed by bands of adhesive provided in the inner segments of the upper portions of the bag 220. Once the adhesive- covered inner bag portions engage another portion of the bag, they would stick together.
  • an automated method of sealing the open end of the film bag 220 can be provided.
  • the constriction assembly 130 could alternatively include a heating element that softens the plastic film bag, thereby bonding it to itself and sealing it closed.
  • FIGS. 6-8 show further detail of the cartridge assembly 200, its replaceable cartridge insert 250 and its operation in association with the container 101.
  • the cartridge assembly 200 includes a casing 210 which holds a cartridge insert 250 therein.
  • the cartridge insert includes a film bag 220 and a rigid film support member 240 that is fixed to the bag 220.
  • the casing 210 includes a casing upper shell 204 which mates with a casing base 208 thereby creating an inner annular cavity 205 there between for receiving the cartridge insert 250.
  • the casing 210 is preferably an annular member that includes a lower annular aperture 209 located on the lower inside edge of the casing 210.
  • the aperture 209 allows the film bag to continuously extend from inside the cavity 205, through the aperture 209 to outside the casing 210.

Description

FACILITY OPERATIONS COORDINATING WASTE DISPOSAL APPARATUS
AND SYSTEM
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional Application No.
61/606,915, filed on March 5, 2012, the specification of which is incorporated herein by reference for all purposes.
TECHNICAL FIELD
[0002] The present disclosure relates to a waste disposal apparatus for coordinating operations in environments that include one or more waste disposal receptacles.
BACKGROUND
[0003] Maintenance of areas where people spend time generally includes waste handling and disposal. In particular industries, such as the health care industry, waste handling and disposal can be more complex, due to the increased sensitivity to bio- hazards and the need to prevent the spread of contaminants. Such complex waste handling environments can experience significantly higher costs associated with waste management. This in-turn drives the need to reduce labor costs in order to deliver quality care in an industry often saddled with budgetary constraints.
[0004] In hospital settings, caregivers and staff often have to dispose of waste from those rooms and areas in which patients are treated and/or stay. A good deal of time is spent trying to deodorize or prevent contamination of those rooms, areas and overall facilities. Often, caregivers or other staff will often carry soiled items or other waste down a hall to a central disposal area, rather than using the closest trash can. This is done to control the growth of bacteria, the spread of viruses and infectious diseases or even simply contain unpleasant odors. However, carrying contaminated waste from one area to another risks the spread of the very bacteria and viruses being contained. Also, such additional time spent on the otherwise simple task of disposing of waste consumes billions of dollars a year when considering the overall volume of waste handled daily by large facilities, such as hospitals.
[0005] Additionally, along with the efficiency problems associated with disposing of waste using contemporary methods, there are also the problems of personnel and supply management. In care giving environments, managers often look for metrics to measure quality of care and resource management. However, knowing precisely how often and when a patient has been checked-on or treated and what supplies are being used in that regard is generally an inexact science. High level managers are left to rely on lower level personnel to monitor and track such activities and information.
[0006] Accordingly, it would be desirable to provide an efficient, safe and cost effective apparatus and system for coordinating operations in environments that include one or more waste disposal receptacles that overcomes the shortcomings of the prior art.
SUMMARY OF THE INVENTION
[0007] In one aspect of the present invention, a waste disposal cartridge for a waste container is provided. The cartridge generally includes a cartridge housing for removably installing over a deposit opening of a waste disposal container, a film casing formed as an elongate tubular member and an annular support ring substantially surrounded by the film casing. The cartridge housing has an annular shape defining an inner aperture for aligning with the deposit opening when installed on the waste disposal container. The inner aperture extends through the cartridge from a first side through to an opposed side. The cartridge housing includes an annular base and an annular cap, wherein the base and cap mate to form a substantially closed inner cartridge chamber between the base and the cap. The film casing folds onto itself so as to compact the film casing along a
longitudinal extent thereof and a segment of the film casing is removably attached to the support ring, wherein the segment is remote from two opposed ends of the longitudinal extent, and wherein the film casing and annular support ring are substantially disposed within the inner cartridge chamber. [0008] The film casing preferably includes a top and a bottom disposed respectively at two opposed ends of the longitudinal extent, wherein the bottom is permanently closed and the top is selectively closeable. When open, the top of the film casing preferably provides access to an inside of the film casing from an outside thereof, and preferably includes a closing element for selectively sealing closed the film casing.

DETAILED DESCRIPTION
[0043] Describing now in further detail these exemplary embodiments with reference to the FIGS. The disclosed technologies improve efficiency, safety and cost effectiveness associated with waste disposal, personnel management and quality of services, particularly in a healthcare facility. The apparatus, systems and methods disclosed herein can be used in a single facility or among remote locations and the scale of the deployment of the technologies can accommodate the needs of almost any organization. While large scale deployments across a big facility and/or multiple small locations will benefit most, advantages can be achieved even by a single waste disposal container employing the disclosed technologies.
[0044] As referred to herein, the term "waste" refers to trash, refuse, unused material, surplus or soiled materials including garbage normally deposited in waste disposal cans. It should be understood that such waste can include conventional or common waste such as paper goods or food or more specialty waste such medical or biohazardous waste.
[0045] As referred to herein, the term "film bag" refers generally to a thin-film thermoplastic bag, such as those made from high-density polyethylene (HDPE), polyethylene high-density (PEHD) or a low density polypropylene (LDPE). Film bags are also known as garbage bags or trash bags and are generally used as a liner for a trash can. Film bags provide a flexible, disposable sack-like container that can hold a volume inside.
[0046] Aspects of the disclosed technologies are directed at minimizing the spread of pathogens and controlling bacterial growth by allowing for the disposal and control of soiled items within a room or area in which they are generated. In this way, bacteria is locally contained and managed before it spreads. Billions of dollars spent in labor for cleaning, disinfecting and deodorizing costs, and the purchase of chemicals can be saved. By locating a waste disposal container in accordance with the disclosed technologies, in each room or area in which waste is generated, such as medical or biohazard waste, pathogens can be immediately controlled, as well as supply inventories and personnel activities can be monitored and managed.
[0047] Aspects of the disclosed technologies provide a self-opening waste disposal system that also self-seals each deposit. Additionally, sensors and data collection technologies used with the disclosed system enable the tracking of patient movements and staff member activities in the vicinity of conveniently located waste disposal cans. The data collected can assist in keeping track of deposits made within the waste disposal can and even notify the custodial staff when the receptacle is full and needs to be emptied. The process saves labor time and effort, allowing more time for patient care.
[0048] The system can include data collection and distribution elements that track time and attendance, collect documentation of the length of time that staff is with patients, provide staff notification or reminders, include employee and visitor tracking, patient ambulation time and distance documentation, and enable the ability to provide real-time tracking for infectious outbreaks. Additional the system can provide alerts to notify staff when patients have not been seen within designated time periods. Alternatively, the system, methods and apparatus disclosed herein need not be limited to healthcare facilities, but could also be used in any setting where waste receptacles are conveniently located and it is advantageous to monitor and track human behavior, such as in the hospitality and entertainment markets. [0049] FIGS. 1 and 2 show an activity tracking apparatus 10 in accordance with aspects of the disclosed technologies. In particular, the activity tracking apparatus includes a waste receptacle container 100 with closable lid 110. An inner cartridge assembly 200 includes a film bag 220 for receiving and holding deposited waste. In addition to the film bag 220, the cartridge assembly 200 includes a casing 210 designed to hold the film bag 220 and dispense it therefrom while providing an annular inner passage for receiving any waste disposed therein. As the film bag 220 is deployed from inside the cartridge assembly 200, it drops down into chamber 150. It should be noted that although the waste receptacle container 100 can include a front door panel to secure and close-off the inner chamber 150, for illustration purposes it has been removed in FIGS. 1 and 2 to more clearly show the film bag 220 hanging inside the apparatus 10. Also, the inner chamber 150 can be supplemented with an internal trash can/box adapted to receive the film bag 220 as it drops down into the inner chamber 150. An internal trash can/box (not shown) can help in unloading the film bag 220 from the receptacle container 100. Such an internal trash can/box can be shaped like a cylindrical can or square-shaped box with an open top, or other shape suitable to fit inside the inner chamber 150 and be pulled out through the front panel door when open.
[0050] FIGS. 3a and 3b show an alternative activity tracking apparatus 11 with slightly modified inside upper surfaces 116a, 116b incorporated into the waste receptacle container 101. It can be further noted that while the access panel 105 is shown in this embodiment, a similar panel could be provided for the waste receptacle container 100 shown in FIGS. 1 and 2. The apparatus 111 further includes an alternate closable container lid 111 that includes an optional sealing protrusion 112 made to interact with the cartridge assembly 200 and close off the inner aperture therein. The protrusion 112 projects down from an inside surface of the lid 111 so that a remote end of the protrusion 112 gets seated inside the inner passage of the cartridge assembly 200. Alternatively, the side tapered walls of the protrusion can be made to engage the inner surfaces of the cartridge assembly 200 in order to seal-off the inside chamber 150 of the container 110, 111. However, the apparatus 11 can be deployed and employed in virtually all the same ways as the apparatus 10. [0051] In accordance with an aspect of the disclosed technologies, the activity tracking apparatus 10 can be deployed in appropriate areas of one or more facilities, where it is desirable to track human activity or even just the waste being disposed. The activity tracking apparatus 10 in accordance with the invention herein, take the form of a waste disposal can. Waste disposal cans are generally conveniently located throughout most facilities were humans dwell, in order to keep the place clean. Thus, the apparatus 10 of the instant invention can be used in public facilities such as sports venues, restaurants, schools, theaters, stores, airports and malls, as well as private or government run facilities, such as government buildings or healthcare facilities, including hospitals, clinics and nursing homes. Anywhere that it can be useful to track human activity and particularly where that activity includes the use of a waste disposal can.
[0052] One aspect of human activity that can be tracked involves the disposal of waste inside the activity tracking apparatus 10 itself. For example, monitoring the content, volume and/or weight of what is inserted into a waster receptacle can assist maintenance personnel in knowing when the garbage bag within needs to be replaced. This can have universal application to all the above-noted environments. However, where more precision tracking is needed, such as in a hospital facility, other aspects of human interaction with the activity tracking apparatus 10 can be monitored. For example, in a classroom or a meeting environment, the apparatus 10 can include sensors for take attendance of the occupants in the room as described further below. Similarly, in a healthcare environment, the apparatus 10 can be used to track the activities of a patient or personnel that interact with the patient or the patient's environment. Additionally, the apparatus 10 can be placed near entrances/exits in order to assist in tracking the entry and egress from those buildings and/or areas. What's more, because many of these same buildings already have waste disposal cans and have space reserved for them, retrofitting and/or incorporating the apparatus in accordance with the disclosed technologies into existing facilities is simplified. Accordingly, the activity tracking apparatus 10 can be either incorporated into most facilities are supplementing and/or replacing the existing waste disposal cans. [0053] FIG. 4 shows a schematic illustration of a deployment of the facility operations coordinating waste disposal apparatus of the present invention. In this way, a group of activity tracking apparatus 10 is shown deployed in remote locations. Although the four apparatus 10 are shown grouped together it should be understood that this illustration is representative of a deployment to one or more particular locations. The four apparatus 10 represent one or more activity tracking apparatus 10 in communication with a computer server 500, regardless of their proximity to one another. In turn, the server 500 communicates with one or more work stations 610 and/or one or more handheld communication devices 620. It should be further understood that while on aspect of the disclosed technologies includes waste receptacles with smart technology as part of the activity tracking apparatus 10, additional activity tracking apparatus can be limited to sensors or RFID tag readers that can be further distributed throughout a facility for tracking activity as further described herein. In fact, the handheld communication devices 620 can include such readers, as well as portable equipment or even vehicles. In other words, a modified version of the activity tracking apparatus 10 can include a separate unit with one or more sensors, a processor and communication elements that can be placed in hallways or areas where a waste receptacle container can not be
accommodated. This will allow for the complete tracking of individuals, inventory and equipment. Also, records of such activity can assist in tracking infectious diseases or individuals suspected of carrying them.
[0054] Server 500 represents one or more elements of computer hardware dedicated to running one or more services as a host. The server 500 can take the form of a database server, file server, mail server, print server, web server, or other functions as known in the field of information technology. In the illustrative example of FIG. 4, the server 500 acts as a communication hub for the overall system. The communications between elements can be by means of wired communication channels 600 or wireless systems 605. While the work stations 610 are shown connected by wired channels 600 and the hand held devices connected by wireless channels 605, it should be understood that any combination of wired or wireless communication between the elements, the server 500 and even each other can be employed. Such wired 600 and wireless 605 communication channels include Ethernet, internet, radio signals, WIFI, cellular, microwave, other wired or wireless communications techniques. In his way, the server 500 can communicate the information compiled from each apparatus 10 to work stations 610 and the work stations 610 can be used to program or operate the apparatus 10. Similarly, the server 500 can communicate with handheld devices 620, which can be deployed to personnel for communicating and/or recording activity at the individual locations. The work stations 610 can include a form of computer, monitors or administrative stations with a graphical user interface. The handheld devices 620 can include tablet computers, cell phones or other portable communication/computational tools. In this way, the server 500 can collect and compile or even re-transmit information received from the activity tracking apparatus 10, work station 610 or handheld devices 620 as necessary.
[0055] One aspect of the disclosed technologies relates to how each activity tracking apparatus receives and seals waste deposited therein. FIGS. 5a -5d illustrate the activity tracking apparatus 11 with a film bag 220 in various stages of waste containment. Inside the apparatus 11, a cartridge assembly 200 is disposed between the container lid 111 and the receptacle container 101. When the lid 111 is open, the cartridge assembly 200 is exposed to the area outside the apparatus 11. But with the lid 111 closed (as shown in FIGS. 5a-5d), the cartridge assembly 200 is contained with the lid 111 above it and surrounding it and the container 101 below it. The cartridge assembly 200 includes an annular cartridge casing 210 and a film bag 220 initially coiled substantially within the casing 210. The exemplary film bag 220 has one open upper end and a closed lower end. The casing 210 is an annular hollow member with an opening along a lower inside edge through which the closed end of the film bag extends.
[0056] In the first stage shown in FIG. 5a, the lower portion of the empty film bag 220 hangs down from the cartridge casing 210 into the inside chamber 150 of the container 101. The cartridge casing 210 initially contains the disposable film bag 220 that gets deployed from the casing 210 through a small annular aperture on the bottom inside edge of the annular casing 210. In the embodiment shown, the apparatus 11 includes a bag constriction element 130 formed as a radially protruding flange. The constriction element 130 is generally disposed below the casing 210 and extends horizontally toward the center of the apparatus 11. The constriction element 130 encourages the film bag 220 to bunch-up and form a bottleneck before hanging down into the inside chamber. The bunched-up bottleneck in the film bag 220 can be more easily twisted, to facilitate the creation of separate sealed compartments between continuous portions of the same film bag 220. With a sufficient amount of film bag 220 pulled out of the cartridge assembly, the lowest portion of the film bag 220 will hang down past the constriction element 130 toward the container chamber 150. In order to facilitate in twisting the film bag 220, relative to the cartridge casing 210, a bottom edge or corner of the film bag 220 can be tethered or attached to an inside of the container inside chamber 150. In this way, the film bag that is attached to the inside of the chamber 150 can not rotate or is limited in how much it can rotate, while the cartridge assembly 200 above is made to rotate as described herein. Once a sufficient volume of waste is deposited within the chamber, the mass will resist rotation on its own, but until that point the internal attachment of the bag will assist in this regard.
[0057] The constriction member 130 can be a semi-rigid element with sufficient bending resistance to generally hold the configuration shown in FIGS. 5a - 5d. However, the constriction member 130 should also be sufficiently yielding to allow deposited waste to be pushed through the constriction member 130 toward the lower part of the bag 220. While the constriction member 130 can be formed by a set of radially protruding fingers, it can alternatively be formed by a retractable mechanism, such as a set of retractable jaws. When waste is being deposited in the bag 220, through the center of the cartridge assembly 220, the waste is pushed past the constriction member. If the constriction member 220 is alternatively more rigid and not yielding, it can be made to mechanically retract and thus allow waste to be deposited within a segment of the film bag 220 just below the constriction member 130.
[0058] As waste is deposited within the film bag 220, an initially deployed segment of bag will get filled, or at least partially filled, as shown in FIG. 5b. The ballooned segments of the bag, as shown in FIGS. 5b-5d represent filled or partially filled segments of bag. Once a deposit is made within the film bag 220 and the lid is closed, the rotational drive mechanism 145 will rotate the cartridge assembly 200 relative to the container 101. With a lower segment of the film bag 220 held or otherwise kept from also rotating, a twist will form in the bottleneck portion of the bag. In this way, a first segment of the film bag containing waste forms a first bag debris cavity 222, which hangs down below the constriction member 130. With at least one complete rotation, the drive mechanism 145 will twist the bag enough to seal-off the first bag debris cavity 222 from the upper region where the cartridge assembly resides. However, it should be understood that 2-3 complete revolutions of the cartridge relative to the film bag would generally ensure a better sealing-off of compartments of the film bag. The number of revolutions needed to seal-off compartments can be dependent upon the type of material used for the film bags 220. Thereafter, opening the lid 111 and inserting more debris will deploy more film bag from the casing 210 and form a second debris cavity 224, such as that shown in FIG. 5c. Once again, the lid can be closed, the cartridge assembly 200 twisted by the drive mechanism 145, with the lower film bag portions held in place, to thereby seal off the second bag debris cavity 224 from the cartridge assembly above. This procedure can be repeated to make third, fourth, or additional debris bag cavities depending on the volumes of the cavities created, the side of the inside chamber 150 and the length of the debris bag 220.
[0059] The rotation of the cartridge assembly 200 can be performed as an automatic process upon the occurrence of a designated event. For example, the lid 110, 111 could automatically close after a set period and then the drive mechanism 145 actuated to rotate the cartridge assembly 200. Alternatively, a user making deposits could press a button or communicate to the apparatus 10, 11, in some way to initiate the lid closing and cartridge rotation. As a further alternative, the apparatus 10, 11 can include an alternative mode that when activated signals the apparatus 10, 11 that the cartridge should not be twisted once the lit is closed. This can be used when syringes are inserted in the film bag. Also, an override mechanism could be provided to alter other default settings or operations of the apparatus 10, 11. [0060] The final part of the film bag 220 to be deployed from the casing 210 is the open top end 221 of the bag. In accordance with an aspect of the disclosed technologies, that film bag open end 221 comes out of the cartridge casing 210, so the bag 220 can be sealed shut. The film bag 220 is initially secured to a film support member 240, which is an annular ring, when it is newly installed inside the casing 210. But eventually, in order for the entire the film bag 220 to be deployed from the casing 210, the bag must be separated (i.e., pulled free) from the film support member 240. Thus, once the entire film bag 220 is deployed, the film support member 240 remains inside the cartridge casing 210.
[0061] The film bag top 221 can include a sealing feature 225 so that the overall film bag can be sealed shut and removed from the container 111. As shown in FIG. 5d, the final debris cavity 226 just before the top of the bag could remain empty or only partially filled in order to make it easier to seal the bag shut. It should be understood that while the top of the film bag 221 with the sealing feature 225 is shown in FIG. 5d as pulled down below the constriction member 130, it could have been sealed prior to being pulled through the constriction member 130. In this way, just after being pulled out of an inner portion of the film casing 210, the sealing feature can be activated either automatically or manually, before it drops or is pushed down below the constriction member 130, into the chamber 150 below. Once the top of the bag 221 is pulled out of the casing 210, the apparatus can initiate a signal that indicates the bag 220 must be sealed, removed and replaced. A more manual alternative could include a color change or striping around the top of the bag 221 to signal to a user that the bag has/is run/running out, needs to be sealed and replaced. A user, such as maintenance personnel, could then use the sealing feature 225 to seal off the bag and push it down into the lower chamber 150. The sealing feature 225 could be something like a Ziploc® bag or other similar bag sealing technologies.
[0062] Alternatively, the bag sealing feature 225 could be formed by bands of adhesive provided in the inner segments of the upper portions of the bag 220. Once the adhesive- covered inner bag portions engage another portion of the bag, they would stick together. As a further alternative, an automated method of sealing the open end of the film bag 220 can be provided. For example, the constriction assembly 130 could alternatively include a heating element that softens the plastic film bag, thereby bonding it to itself and sealing it closed.
[0063] FIGS. 6-8 show further detail of the cartridge assembly 200, its replaceable cartridge insert 250 and its operation in association with the container 101. In particular, the cartridge assembly 200 includes a casing 210 which holds a cartridge insert 250 therein. The cartridge insert includes a film bag 220 and a rigid film support member 240 that is fixed to the bag 220. The casing 210 includes a casing upper shell 204 which mates with a casing base 208 thereby creating an inner annular cavity 205 there between for receiving the cartridge insert 250. As shown, the casing 210 is preferably an annular member that includes a lower annular aperture 209 located on the lower inside edge of the casing 210. The aperture 209 allows the film bag to continuously extend from inside the cavity 205, through the aperture 209 to outside the casing 210. Accordingly, in order to load a new cartridge insert 250, one would open the casing 210 by removing the casing upper shell 204 from the casing base 208. This would allow a new cartridge insert 250 to be inserted on top of the casing base 208 and then allow the casing upper shell 204 to cover and enclose most of the cartridge insert 250 therein. Initially, most of the film bag 220 is contained within the casing 210. As the film bag 220 is pulled downward into the container 101, more of the film bag 220 gets pulled out of the casing 210. Eventually, the entire film bag 220 gets pulled out of the casing, leaving the film support member 240 behind. The further cross-sectional views in FIGS. 7 and 8 show a similar cartridge assembly 200 mounted within a cross-sectional view of the container 100 from FIGS. 1 and 2. Also, FIGS. 9-11 show a cartridge assembly 200 by itself, removed from the apparatus 10, 11.
[0064] The cartridge insert 250 preferably includes the annular film support member 240 and a tightly compacted film bag 220 surrounding it. The film support member 240 can be formed as a flat cylindrical band made of a light weight and inexpensive material that can hold its own weight and provide sufficient structure to the film bag when bunched around it. The film support member 240 can be made of cardboard, thick paper, plastic or other suitable material. The film bag is placed around the film support member 240 in a collapsed state so it is folded onto itself to create collapsed film folds 230. Also, a bonded segment 235 of the film bag 220, near the upper portion of the film support 240, holds the film bag 220 to the film support member 240. The bonded segment 235 performs multiple functions for the cartridge insert. In particular, it serves to hold the film bag to the film support member and allows the film insert to be more easily mounted within the cartridge assembly. Also, as the bag is deployed from the lower aperture 209 and reaches the final stages of deployment, a user will note the resistance of the bag being held at the bonded segment 235. This resistance is an indicator that the bag has reached its end and needs to be pulled out and sealed. Further indicators of the bag reaching its end can be provided on the bag itself, such as a change of color, striping or other alert type symbol(s) which informs a container user that the bag has reached its end. Thereafter, the bonded segment 235 of the film bag 220 can be torn away from the support member 240 so the sealing element 225 can be pulled down and out of the casing for sealing off the bag.
[0065] FIGS. 7 and 8 show a further optional element not shown in FIG. 6 which is added to the cartridge assembly 200. In particular, the casing cover 206 is shown mounted on top of the casing upper shell 204. Preferably, the casing cover 206 is an inexpensive disposable element that can be applied over the cartridge casing 210 to keep the casing clean and prevent direct engagement of waste deposited in the apparatus 10 with the cartridge assembly 200. In accordance with an aspect of the invention herein, the cartridge casing 210 can be a reusable and/or refillable element whereas the cartridge insert 250 gets used up and replaced. Accordingly, in order to allow the cartridge casing 210 to be reused while minimizing contamination, the casing cover 206 provides an appropriate disposable protection. It should be understood that the casing cover 206 could be removed and disposed of coincident with replacement of the cartridge insert 250. Thus, as the film bag reaches its fully deployed state, a user can take the cartridge cover 206 off and insert it in the bag before finally sealing it. In fact, before sealing the bag 220, the cartridge casing can be opened, the film support member 240 removed and also placed inside the film bag 220 for disposal. Alternatively, the casing cover 206 could be replaced more or less frequently as desired.
[0066] FIG. 9 shows the cartridge assembly 200 removed from the activity tracking apparatus 10, 11. The cartridge assembly 200 shown does include a newly inserted film cartridge insert 250, although only a portion of the film bag 220 is visible in FIG. 9. An inside area, which forms the waste disposal passage 215 through the cartridge assembly 200 should remain unobstructed, with the exception of the film bag 220 at one end. The cartridge assembly 200 shown also includes a casing cover 206. Preferably, the cartridge assembly 200 is removable and/or replaceable from within the activity tracking apparatus 10, 11. In this way, it can be replaced, cleaned and/or simply refilled and reloaded into the waste receptacle container 100, 101. FIGS. 10 and 11 further show a cartridge retaining posts 207 that project downwardly from the casing base 208. The cartridge retaining post preferably holds the cartridge in place relative to the rotational drive mechanism 145 within an upper portion of the waste receptacle 100, 101. As shown in FIGS. 6-8, preferably the waste receptacle container 100, 101 includes a rotary drive mechanism 145 which when activated, engages the cartridge retaining posts 207 and rotates the cartridge assembly 200 for twisting the film bag to seal-off a segment below the constriction assembly 130. Although shown in cross-section, the rotational drive mechanism can include an annular disk-shaped gear made to couple with the retaining posts 207.
[0067] FIGS. 12 and 13 show the casing cover removed from the other portions of the assembly. One notable aspect of the casing cover 206 is that an inner extension 216 can be made to extend lower than the outer portion of the casing cover. This inner extension 216 provides added protection from contamination to the inner portion of the cartridge assembly.
[0068] FIGS. 14-17 show further detail of the cartridge insert 250 by itself removed from the further assemblies. In particular, FIG. 14 shows a fully extended cartridge insert that has been pulled out, but not pulled off, from the film support member 240 (shown in phantom). In this expanded configuration, it reveals the full extent of the film bag 220. In this way, a bottom 229 of the film bag is pulled and expanded away from the top 221 of the film bag which includes the sealing feature 225. Additionally, shown in phantom, is film support member 240, bonded to the inside of the bag 220. As noted previously, the film bag 220 is bonded to the film support member 240 at the bonded segment 235. Preferably, this bonded segment 235 is located near an upper portion of the bag 221 so that a top edge of the film support member 240 is a pre-defined distance X from the top edge 221 of the bag. FIG. 15 further shows the film support member 240 by itself separated from a film bag 220 and all other elements. The film support member 240 can be provided with retaining notches 242 which are designed to mate with receiving protrusions within the casing upper shell 204 of the cartridge assembly (not shown). These retaining notches 242 help maintain the cartridge insert 250 from rotating relative to the casing 210 during the bag rotation function.
[0069] FIGS. 16 and 17 show a further relief of the cartridge insert 250 in cross section. In particular, FIG. 17 shows the bonded segment 235 where the film bag 220 is joined with the film support member 240. It should be understood that while a length Y of film bag 220 is shown bonded to the film support member 240, that length Y can be varied to accommodate a desired separation strength. In this way, a sufficient bonding strength is provided to hold the film bag 220 to the film support member 240. But the bonding force should not be so great that a user or an automated mechanism can not tear the film bag 220 away from the film support member 240 in the final stages of deployment for activating the sealing feature 225. The film bag 200 can be slightly thickened or reinforced along the bonded segment 235, so it maintains its integrity when ripped free from the support member 240.
[0070] FIGS. 18 and 19 show further aspects of the invention, particularly relating to an alternative constriction assembly used to squeeze an intermediate portion of the film bag, in order to more easily twist the film bag and seal-off those portions of the film bag below the constriction assembly. FIGS. 18 and 19 show a bottom view from inside the apparatus, with an alternate constriction member 131 below the film bag 220 above (in the orientation of FIGS. 18 and 19, the constriction member 131 lies in front of the film bag). Also visible in these views are the rotational drive mechanism 145 mated with the cartridge retaining posts 207.
[0071] Constriction member 131 comprises two cooperating jaw arms that surround opposite sides of the debris bag 220 as it hangs down between the cartridge assembly 200 and the inside chamber 150. The constriction member 131, shown in open position in FIG. 18, allows debris to pass through from outside the waste receptacle container 100, through the cartridge assembly 200 debris passage 215 and into the film bag 220 within the inside chamber. In the closed position shown in FIG. 19, the arms of the constriction member 131 squeeze opposed portions of the bag together to assist in the twisting of the bag. FIG. 19 also includes a shielding ring disposed between the rotational drive mechanism 145 main gear and the constriction member 131. The constriction member 131 can be automatically actuated once the lid 110, 111 is closed, in conjunction with the twisting operation of the cartridge 200.
[0072] FIGS. 18 and 19 further show ultra-violet (UV) lighting windows 212, 214. These windows allow the reflection of a UV light emitted from inside the container 100, 101 to reflect upwardly and into the upper lid area of the can when the lid is closed. Preferably the inside surfaces of the lid can include reflective surfaces that can further spread the UV lighting and disinfect the upper regions of the activity tracking apparatus 10. Also, it is preferable that the film bags used in the waste container are transparent and allow UV light to pass therethrough. In this way, the UV light can further disinfect what is inside the film bag as well as outside the film bag, but inside the waste disposal can.
[0073] FIG. 20 shows a further aspect of the activity tracking apparatus 10. In particular, the waste receptacle container 100 can include a way of opening the container without physically touching it. Because touching the waste container can further the spread of bacteria either picked up from the can or transmitted to the can, it is advantageous to provide a means of automatically opening the can without physically touching any of the surfaces. One aspect of this hands free opening feature involves a proximity sensor that senses that a user has indicated the can should be opened. For example, a non-contact insertion zone 120 can be provided as shown in FIG. 20 in which the user's foot can be inserted without touching any of the surfaces and a sensor such as a light based sensor or a motion sensor detecting the presence of the foot can then activate the opening of the can. Additionally, in order to limit unauthorized tampering with the activity tracking apparatus 10, one or more levels of security can be implemented before the lid will open or even the front access panel. For example, personnel authorized to make deposits within the activity tracking apparatus 10 can carry either a physical key or a wireless key. A wireless key has advantages since it avoids further contact between the apparatus 10 and the user. Examples of wireless keys include an RFID tag carried by personnel that is detected by sensors in the apparatus. Alternatively, a tablet computer or other hand held communication device can be used by entering access codes either signaled directly to the apparatus 10 or indirectly through a server 500 or other communication network and back to the apparatus 10. Also, one level of access can open the lid, while another level of access can be used for accessing the front panel.
[0074] FIGS. 21-23 show an alternative film cartridge assembly 201 formed with a case base 214 and a case top 218. This alternative cartridge assembly 201 still holds a cartridge insert that includes a film bag. Like the earlier disclosed cartridge assembly 200, this alternative also encases the film support member 240 and film bag 220 in an inner annular chamber. Here, the case top 218 covers a top and inner side of the cartridge insert, while the case bottom 214 helps encapsulate the cartridge insert covering the outer side and bottom. As shown in FIG. 24, the case base 214 includes mating apertures 219 for coupling to a rotational drive mechanism 300. As shown in FIGS. 28-30, the rotational drive mechanism 300 includes a set of vertical engagement rods 307 designed to mate with the alternative film cartridge assembly. In particular, the various rods 307 match the size and pattern of the mating apertures 219. The film bag 220 gets crammed between the film support 240 and the engagement rods 307. Such tall vertical rods 307 ensure that the cartridge assembly remains mounted on and coupled to the rotational drive mechanism, particularly while it rotates. FIG. 31 shows a further alternative film support member 241 that includes retention tabs 245. The retention tabs 245 are also intended to mate with the engagement rods 307. The tabs 245 include tab apertures 247 that are appropriately sized and align with the engagement rods 37.
[0075] The activity tracking apparatus 10 in accordance with the disclosed technologies can serve many functions, in addition to keeping track of the when the receptacle cans are opened and closed. For example, every activity tracking apparatus (also referred to herein as a "receptacle can" or simply "can") will have an electronic "reader," that reads RFID tags carried by employees, visitors and patients, as well as tags incorporated into supplies or equipment. For example, each can will use replaceable film bag inserts that include RFID tags. When the cans or device with readers are distributed throughout a location, the system can maintain a record of a serial number (or tracking number) for each can/reader and where they are located (installed) by way of Wi-Fi or other network communication technique. The tracking devices will include software that when executed will operate each can and/or the device containing the reader. In this way, a central processing system can maintain a record of not only where each can/reader is located, but also, which film bags were used in which particular cans. Such waste cans and/or readers used in accordance with the activity tracking system herein, will be referred to more generally as activity tracking apparatus.
[0076] Additionally, activity tracking apparatus can include at least two types of readers; namely a proximity reader that will identify who is in an area/room in close proximity and a close-up reader to identify who actually makes deposits or gets close to the device.
[0077] Combining the location information for each tracking apparatus, with properly scaled floor plans of a facility, distances can be calculated, such as how far a person has traveled (ambulated), thereby calculating energy consumption calories etc. Also you can locate where an individual is at any given moment in the facility.
[0078] The system can record what time a deposit is made in each can and who made the deposit. Also, the system can page housekeeping when the unit is either full, which can be activated either by weight or by volume. Recording the weight and tally of the contents of each film bag, as well as the count of film bags used, can be useful for tracking activities. When a film bag insert is placed in the can, the RFID tag is read, which information gets transmitted by communication network, such as Wi-Fi, to a central processor to validate the tag and then the unit will work. Alternatively, an inventory is uploaded to the central processor by other means or another source. The activity tracking apparatus can provide information to one or more coordinating processors that will track inventory and report how frequently the activity tracking apparatus is visited and used. Also, statistics can be maintained of how much waste is being produced by patients and/or personnel working with patients. When the can is full, it can automatically send a message, such as a text or page, to housekeeping or other maintenance personnel. Such a message could be routed to electronic communication devices carried by individual personnel, such as a pager, cell phone, hand-held data device, tablet computing device, laptops, etc. In accordance with one aspect of the technologies disclosed herein, if housekeeping is tied up, they can they send a signal back that acknowledges they are aware of the circumstance. Through its array of sensors and tracking devices, the central processor will know where housekeeping/maintenance personnel are. This type of information can be used by management for maximizing their labor force.
[0079] Each type of employee can have a different value for tracking purposes. For example, Nurses and Doctors can have different authorization levels with regard to interacting with an individual activity tracking apparatus. As a further example, housekeeping alone can be provided with authorization to open the access door of the can. In this way, when housekeeping enters a room containing an activity tracking apparatus, the RFID tag they carry will identify them as housekeeping. The sensors and processor in the can will recognize this level of authorization and allow them to open the can if needed. The actual opening of the access panel on a particular activity tracking apparatus can be activated from a non-contact foot pedal, as described above, or alternatively signaled through a hand-held communication device, like the cell phone, tablet computer or other similar communication devices described above. The hand-held communication device can also include encryption or authorization codes, which can likewise activate features of the can. [0080] When the can is full, the unit can shut down, with the lid closing until it is put back into service mode. The weight of the film bag can be calculated by incremental weight per each dropping, which deposit information can also be maintained and tracked by a processor. The system can further monitor all of the weights on a daily basis across numerous activity tracking apparatus. The unit can include a volume sensor or even an ultrasound device in order to measure weight or volume in accordance with the function. In addition to the film bag 220, the cartridge assembly 200 includes a casing 210 designed to hold the film bag 220 and dispense it therefrom while providing an annular inner passage for receiving any waste disposed therein.
[0081] As part of inventory control, housekeeping can have hand held electronic devices, used to enter inventory information for deposits in the can. For example, an entry can be made indicating 3 chucks and 2 diapers were deposited in Room 1. A customized application can be provided on the hand held electronic device to simplify this process with icons and easy data entry techniques. Alternatively, the activity tracking apparatus can have "smart technology" that can guess the type of deposit that was made, based on size and/or weight. For example, the weight of a chuck or diaper may be estimated, so when the system measures a deposit having the corresponding weight, it will prompt the user for data, with a guess based on the weight, which can be overridden by the user if the guess is incorrect.
[0082] When personnel enter a room or area, the activity tracking apparatus can not only record that they are in the room but can calculate the exact time they spent in the room. Such time can be correlated to patient treatment time. Also, the system can even correlate this information with whether the patient was in the room when the nurse or other personnel was there. Patients should be recorded and tracked with the system. The system can also allow the nurse or other personnel to program the amount of time the patient must be seen during her shift. The nurse could have the flexibility of calculating the exact time min, hours, etc.
[0083] Additionally, the system can calculate what time personnel enter a facility, such as what time nurses arrive at the hospital. This can be done through activity tracking apparatus situated near main or auxiliary entrance/exit doors to take attendance for them and when they arrived at their proper destination. This will then take their timecard to when they actually arrived on their floor.
[0084] Additionally, with blue prints of a facility, distances between activity tracking apparatus can be known, thus providing the system a better measure of distances as they relate to activity in proximity to the various activity tracking apparatus. Knowing the distance between doors and/or rooms can be extrapolated to learn further distances within a facility. Much of this distance information, such as patient ambulation, can be reported back to personnel, such as nurses and doctors, to assist with care. Also, this information can be used to calculate patient energy expenditures, which can further effect dietary recommendations for that patient.
[0085] Medical residency candidates can be notified after they have reached a certain amount of hours for the week, as it is important for them to not exceed their maximum number of hours for the week. They can even be automatically paged or sent a message by text, email or other means by the system when they exceed the hours or come close to the maximum. Similarly, the system can track personnel movement, such as if a particular nurse does not move from his/her desk or does not visit the appropriate patients, a supervisor can be sent a message or a record otherwise logged for that employee.
[0086] The system can track exact usage, particularly useful for tracking inventory. Since each film bag has an RFID, the system will know whether each bag was filled before being replaced. In fact, the system should be able to track the location of the bags, within the facility.
[0087] Additionally, there can be different levels of monitoring for the different levels of administration, such as a CEO, Nursing Director, Nursing Supervisor or Housekeeping Director. Also, the system can have several default functions that the system in the location will have to confirm:
1. Default on for top lid always open; 2. Default delay when item dropped into can (e.g., 5 seconds); and
3. Default film bag cut-off level for signaling it is time to seal it shut and replace it.
[0088] Another option involves tracking visitors. When visitors come in, they will get a tag and it will be defined in the computer by security where they are permitted or intend to go. If the visitor deviates from the intended course or strays into a restricted access area, an alert can be triggered by the system. Various levels of movement sensitivity can be programmed as desired to reflect when security or the visitor is notified.
[0089] There may be a situation where two inventory tracking devices are placed in the same room: one for regular garbage and one for medical waste. Therefore, the unit top door can be closed constantly and be opened when the proper employee walks by. The can should close when the employee walks away.
[0090] Patients, employees and visitors can have RFID elements in their patient wrist band or employee/visitor badge. Each RFID chip can be entered into a local computer for their institution for registration and various levels of permission. For example, a nurse may have permission to be identified as not being able to have access to garbage removal. A nurse or patient may have restrictions as to where to go in the building. Housekeeping can be paged or sent a message when the unit is full. Also, alternatively an electronic hand held device carried or used by housekeeping can determine the weight of the unit or bag with contents.
[0091] It is also possible to have more than one activity tracking apparatus, in the form of a waste disposal can, disposed in the same room. This can be useful for special medical waste that needs to be separately disposed and/or tracked from generic medical waste. The nursing and/or medical staff can potentially have access to both containers. Also, the two different containers can operate in different modes. For example, one can default to an "initially open" mode, freely allowing deposits, but closing to seal- compartments only between deposits, while the other container is typically in an "initially closed" mode that needs to be opened for deposits. Also, the system can be programmed to automatically close the can lid at set intervals, such as 5 seconds after the can receives a deposit. The system could be programmed to be adjusted. Alternatively, the system can be programmed to automatically close with each deposit.
[0092] Activity tracking can be applied particularly well to patients. The system stores patient names and room assignments, so the sensors will detect who those patients have been treated or seen by. This can further be integrated into the facility medical records system. For example, if the forty patients assigned to the nurse have not been seen by the nurse during her 8 hour shift, it will identify that the nurse has not been in all the rooms and her electronic hand held device will receive a notification. That electronic hand held device can be the communication hub for the nurse or other personnel. Assuming a patient who is incontinent and must be seen every 2 hours, the nurse can program her electronic hand held device to remind her and alert them. Also, this goes to the electronic chart to document how long the nurse or employee was with the patient and with the hand held device, they can actually have a pop up of which patient they came to see and then they simply have to acknowledge same if it is patient one or patient two. Eventually this becomes the electronic medical record data collector and browser.
[0093] In accordance with an aspect of the technologies discloses herein, the interaction staff and patients can be monitored, maintained as records and reviewed for patient care and personnel management. Activities that occur outside an area with the type of activity tracking apparatus described above, could alternatively track activity through a sensor in an electronic device carried by personnel or even on equipment carried by the patient. For example, a patient's walking aid, wheelchair or even wheeled IV bag stand, can include a supplemental tracking device to enable communication with the system and track patient activities in hallways or other areas away from the activity tracking device. Also, the facility staff can carry such an apparatus or even have it incorporated into a hand-held electronic device they already carry, like a cell-phone or tablet computer. Such an enhancement carried by facility personnel, such as doctors, nurses or other treatment staff, can record those patient interactions that occur away from the patient's room and/or outside the range of the main activity tracking devices. [0094] The system can tracking employee time, distances moved, motion, including patient motion in a bed or room, a patient or worker who is not moving for period of time. Tracking employee/staff time can be useful for tracking work hours and
attendance. Also, in addition to individuals carrying or wearing RFID tags, such tags can be incorporated onto wheelchairs, gurneys, and other equipment as an alternative.
Tracking movement can help identify the movement of infectious outbreaks, by knowing in real-time the movement of visitors, employees and patients. Also, the whereabouts of particular staff, such as doctors or nurses, can be identifying for paging or passing messages to those individuals. Also, the system will record the last person to see a patient or all people that visited with that patient, as well as patient to patient contact. If particular patient-to-patient visits are restricted, an alert can be distributed when such prohibited activity occurs. Similarly, if staff did not make the appropriate rounds to patients or other duties, the system can notify the staff member, a supervisor or other personnel.
[0095] Additionally, as noted above, the activity tracking system of the instant disclosure need not be limited to healthcare facilities. For example, is could be used in schools and buses for tracking the day-to-day activities of students, teachers and other personnel working with schools and students. In this regard, well distributed activity tracking sensors, in waste cans and supplemental locations can help take student attendance, from the moment they step on their school bus and continue to track them in school. Records of attendance can even be tied to student health care records. Each student can be assigned an identification card they can carry or wear, which included an RFID or other trackable element. This will allow a school nurse and/or administrator to keep a record of student attendance and movements throughout a school facility. Such a system can even be used to help stop bullying, by monitoring particular students activities in relation to other students. Also, by including RFID readers on buses or electronic devices carried by teachers or parents on school trips, the system herein can ensure no student goes missing. Such electronic devices could include GPS tracking technology in order to pinpoint the location of the reader, which in-turn pinpoints the
student/teacher/person being tracked. [0096] A further aspect of the disclosed technologies allows for automatic alerts or messaging in response to particular events. For example, if a student is not picked up on the way to school, the system can automatically send an e-mail or text message to a parent/guardian indicating that they were not picked up. Similarly, a school trip chaperone can quickly know whether all students have boarded the bus, prior to leaving from a remote location, since the system can take attendance and automatically report whether anyone is missing or not checked-in.
[0097] Also, when the bus reaches the school, the system will know the number of children on board that bus should match the number of children that enter the school facility. The activity tracking device can be distributed throughout the school facility, such as at the entrances/exits, in classrooms, bathrooms, gymnasium, auditorium and other areas.
[0098] Additionally, the system can be used for alerting particular types of activities. For example, if a student is alone for more than a pre-determined period (such as 5 minutes), a signal can be sent to a teacher or administrator to warn them of the situation. Similarly, if a known bully is alone with another child or even in proximity with a known victim of that bully, an alert can be sent out. When the students go out on recess, the activity tracking system can monitor and verify their return back into the facility, or potentially alert if they do not return by a designated time. In addition, if a child or two are in a classroom and there is no teacher, this could also initiate an alert for student safety and protection. Further, if a child leaves their RFID tracking tag in an area, this can be detected as a time period of no movement in an improper part of the facility, so an alert can be distributed.
[0099] Also, just as with tracking students' arrival at the beginning of a school day, their departure and drop-off can be similarly tracked. What is more, parents/guardians can even purchase and incorporate an RFID reader in their home, in order to monitor the student's arrival from school. Thus, working parents/guardians that can not be home when the kids get off the bus, can be reassured that their child has arrived on-time. [00100] As a further alternative, the activity tracking system can be incorporated into hotels and/or restaurants for tracking activity therein. Such a system can monitor hotel maids, maintenance, bell-hops, and others. Also, using the waste disposal can that includes the activity tracking functions described herein, housekeeping can be notified when a waste can needs to be changed. This is particularly useful in restaurants, where it is often difficult or time consuming to repeatedly enter the restrooms in order to check the status of waste cans.
[00101] Additionally, with regard to bathrooms, in combination with the automatic hand washers, automatic hand dryers or paper dispensers, automatic doors can help reduce the spread of germs. Not just entryway doors, but also bathroom stall doors or even toilet seats, can be made to open/lift automatically. Also, employee activities in a bathroom can be monitored. For example, when someone enters a bathroom stall, in addition to the door automatically opening/closing as needed, the system can alert management if they do not wash their hands afterwards. Additional non-contact bathroom enhancements can also be introduced, such as automatic toilet paper and/or paper towel dispensers.
Tracking the usage of such dispensers can also help track usage and disposal of those items, which can be helpful for tracking inventories. An easy-to-identify proximity or movement sensor can be provided, allowing the patron/employee to be detected for activating the appropriate door, toilet seat or dispenser.
[00102] The system described herein is also applicable in the Home Care setting.
Nurses, aides or other personnel assigned to help a patient in their home, can carry/wear an RFID tag, which is read by an activity tracking apparatus installed in the home. This can be used to document what time the health care worker arrives and leaves, document the amount of waste being deposited or even the type of waste being deposited, as disclosed above with regard to the hospital setting. Further, by measuring what types of items can deposited and are removed from the activity tracking apparatus, pilferage can be deterred and/or monitored. Certain items, such as bed chucks, diapers, etc. can include RFID tags that can be tracked and monitored, as described herein. The tracking of these activities can become part of a comprehensive electronic record for an at-home patient, in order to reduce home care fraud and abuse. [00103] Additionally, the apparatus 10 can include a load sensor in order to automatically determine the volume and or weight of the waste deposited within the apparatus 10. For example, ultrasound can be used to detect these aspects of what has been loaded into the film bag 220.
[00104] It will be appreciated that variations of the above-disclosed and other features and functions, or alternative thereof, may be desirably combined into many other different systems or applications. Various presently unforeseen or unanticipated alternatives, modifications, variations, or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the following claims. In addition, the claims can encompass embodiments in hardware, software, or a combination thereof.
