Abstract

A waste management system and associated method are used to control routing of an autonomous waste receptacle in a facility. The autonomous waste receptacle includes a cavity for storing trash, a trash level sensor for sensing a level of trash stored therein, and a motor operative to move the waste receptacle. Position trackers sense positions of the autonomous waste receptacle and of patrons in the facility. Additionally, concession consumption concession consumption data indicative of sales performed by concessions in the facility are stored. A processing subsystem controls the waste receptacle to move autonomously in the facility along a route determined according to correlations between concession consumption data, trash levels monitored by the waste receptacle, and patron positions.

First claim

What is claimed is:

1. A waste management system for use in a facility, the waste management system comprising:
a waste receptacle configured to move autonomously in the facility, to monitor a trash level of the receptacle, and to communicate wirelessly with other components of the waste management system;
at least one patron sensor configured to sense patrons within the facility, and to communicate patron sensing information to other components of the waste management system for determining positions of the patrons;
a concession consumption database storing concession consumption data indicative of sales performed by concessions in the facility during each of a plurality of time periods;
a communication network providing wireless communication services between components of the waste management system including the waste receptacle and the at least one patron sensor; and
at least one processor configured to control the waste receptacle to move autonomously in the facility along a route determined according to correlations between concession consumption data stored in the concession consumption database, trash levels monitored by the waste receptacle, and patron positions determined according to the patron sensing information.

2. The waste management system of claim 1 , wherein the at least one processor is configured to perform functions to:
maintain a waste receptacle position database identifying, for each of a plurality of time periods, the position of the waste receptacle in the facility during the time period;
maintain a trash level database identifying, for each of the plurality of time periods, the trash level of the waste receptacle as monitored by the waste receptacle;
maintain a patron position database identifying, for each of the plurality of time periods, the positions of patrons in the facility during the time period based on the patron sensing information communicated by the at least one patron sensor;
maintain the concession consumption database; and
maintain a concession database identifying the positions of the concessions in the facility.

3. The waste management system of claim 1 , wherein the at least one processor is configured to perform functions to:
calculate a correlation between a rate of increase in trash level of the waste receptacle, determined according to the monitored trash level of the waste receptacle, and a number of patrons positioned near the waste receptacle, determined according to positions of patrons determined based on the patron sensing information;
estimate positions of patrons in one time period according to the positions of the patrons determined according to the patron sensing information for previous time periods;
calculate a route for the waste receptacle in the facility according to an estimated trash level for the waste receptacle in the one time period calculated based on the estimated positions of patrons in the one time period and based on the calculated correlation between the rate of increase in trash level of the waste receptacle and the number of patrons positioned near the waste receptacle; and
control the waste receptacle to move autonomously in the facility along the calculated route.

4. The waste management system of claim 1 , wherein the at least one processor is configured to perform functions to:
calculate a correlation between concession consumption data and a rate of increase in trash level of the waste receptacle, determined according to the monitored trash level of the waste receptacle;
calculate a correlation between concession consumption data and a number of patrons positioned near each concession in the facility, determined according to positions of patrons determined according to the patron sensing information;
calculate estimated concession consumption in one time period according to estimated positions of the patrons determined according to the patron sensing information for previous time periods and according to the calculated correlation between concession consumption data and the number of patrons positioned near each concession in the facility;

calculate an estimated trash volume for the waste receptacle in the one time period based on the estimated concession consumption and the calculated correlation between concession consumption data and the rate of increase in trash level of the waste receptacle; and
calculate a route for the waste receptacle in the facility according to trash levels for the waste receptacle in the one time period estimated based on the estimated positions of patrons in the one time period and based on the calculated correlation between the rate of increase in trash level of the waste receptacle and the number of patrons positioned near the waste receptacle; and
control the waste receptacle to move autonomously in the facility along the calculated route.

5. The waste management system of claim 1 , wherein the at least one processor includes a waste management server communicatively connected to the waste receptacle, the at least one patron sensor, and the concession consumption database across the communication network.

6. The waste management system of claim 1 , wherein the at least one patron sensor comprises a network of sensors disposed at known locations throughout the facility, each sensor of the network of sensors is configured to sense patrons located proximate to the sensor, and the at least one patron sensor is configured to determine positions of patrons based on the known locations of the sensors and the patrons sensed by each sensor.

7. The waste management system of claim 1 , wherein the at least one patron sensor receives patron position information from an electronic device carried by each patron.

8. A waste management system for controlling routing of an autonomous waste receptacle in a facility, the system comprising:
the autonomous waste receptacle comprising:
a cavity for storing trash;
a trash level sensor for sensing of level of trash stored in the cavity;
a motor operative to move the waste receptacle; and
a processor operative to control the motor to move the waste receptacle autonomously along a route;

a first position tracker configured to sense a position of the autonomous waste receptacle in the facility; and
an autonomous waste management server configured to:
store in one or more databases records of positions of the autonomous waste receptacle and of levels of trash in the autonomous waste receptacle sensed at a plurality of different times;
calculate, based on the stored records of positions of the autonomous waste receptacle and of levels of trash in the autonomous waste receptacle, a route for the autonomous waste receptacle; and transmit the calculated route to the autonomous waste receptacle to control the autonomous waste receptacle to move the waste receptacle autonomously along the calculated route.

9. The waste management system of claim 8 , wherein the autonomous waste management server is configured to calculate and transmit to the autonomous waste receptacle a route for the autonomous waste receptacle to be emptied when the sensed level of trash exceeds a predetermined threshold.

10. The waste management system of claim 8 , further comprising:
a second position tracker configured to sense positions of patrons in the facility,
wherein the autonomous waste management server is configured to store in the one or more databases records of positions of the patrons sensed at the plurality of different times, and
wherein the autonomous waste management server is configured to calculate the route for the autonomous waste receptacle based on correlations between positions of the patrons and levels of trash in the autonomous receptacle at the
