## Abstract

A dispensing system includes a container within which a material is contained and an actuation device movably supported with respect to the container. The actuation device is movable between a first position and a second position. The dispensing system includes a control system. The control system includes an engagement portion in movable engagement with the actuation device. The control system includes a control portion. As the actuation device is moved from the first position to the second position a first time, the control portion does not restrain movement of either the engagement portion or the actuation device. As the actuation device is moved between the first position and the second position a second time within a predetermined time period after the first time, the control portion restrains movement of at least one of the engagement portion or the actuation device.

## Claims

### Claim 1

A dispensing system comprising:
a container within which a material is contained and from which the material is dispensed;
a sensor coupled to the container and configured to detect a presence of a user in proximity to the dispensing system; and
a control system coupled to the sensor, the control system including a logic controller, wherein:
as the sensor detects the presence of the user in proximity to the dispensing system at a first time, the control system is not configured to inhibit a dispense event such that at least some of the material is dispensed from the container at the first time, and
as the sensor detects the presence of the user in proximity to the dispensing system at a second time within a predetermined time period after the first time and after the dispense event at the first time is complete, the predetermined time period controlled by the logic controller, the logic controller delays a subsequent dispense event such that no additional quantity of the material is dispensed from the container at the second time or dispensed during an entirety of a time period between the first time and the second time but the logic controller does not inhibit the additional quantity of the material from being dispensed from the container at a third time after the predetermined time period based upon the sensor detecting the presence of the user in proximity to the dispensing system at the second time.

### Claim 2 (depends on 1)

The dispensing system of claim 1, wherein the predetermined time period is fewer than ten seconds.

### Claim 3 (depends on 1)

The dispensing system of claim 1, comprising a housing within which the container is housed.

### Claim 4 (depends on 3)

The dispensing system of claim 3, wherein the sensor is housed within the housing.

### Claim 5 (depends on 4)

The dispensing system of claim 4, wherein the control system is housed within the housing.

### Claim 6 (depends on 1)

The dispensing system of claim 1, wherein the sensor comprises at least one of an active sensor, a passive sensor, an infrared sensor, a parallel sensor, a triangulated sensor, a position sensitive sensor, or a time of flight distance sensor.

### Claim 7 (depends on 1)

The dispensing system of claim 1, wherein the sensor comprises at least one of a capacitive sensor, an inductive sensor, a microwave sensor, an optical sensor, a sonar sensor, or a laser sensor.

### Claim 8 (depends on 1)

The dispensing system of claim 1, wherein the container comprises an outlet through which the material is dispensed and the sensor comprises a proximity sensor that communicates with the outlet through the control system to inhibit the subsequent dispense event.

### Claim 9

A dispensing system comprising:
a container within which a material is contained and from which the material is dispensed through an outlet of the container;
a sensor coupled to the container and configured to detect a presence of a user in proximity to the dispensing system; and
a control system coupled to the outlet and the sensor, the control system including a logic controller, wherein:
as the sensor detects the presence of the user in proximity to the dispensing system at a first time, the control system is not configured to inhibit a dispense event such that at least some of the material is dispensed from the container through the outlet at the first time, and
as the sensor detects the presence of the user in proximity to the dispensing system at a second time within a predetermined time period after the first time and after the dispense event at the first time is complete as determined by the logic controller, the control system is configured to delay a subsequent dispense event such that no additional quantity of the material is dispensed from the container through the outlet during the predetermined time period, wherein the control system is configured to inhibit the subsequent dispense event from occurring until after the predetermined time period, wherein:
the sensor comprises at least one of an active sensor, a passive sensor, an infrared sensor, a parallel sensor, a triangulated sensor, a position sensitive sensor, or a time of flight distance sensor.

### Claim 10 (depends on 9)

The dispensing system of claim 9, wherein the predetermined time period is fewer than ten seconds.

### Claim 11 (depends on 9)

The dispensing system of claim 9, wherein the logic controller comprises a microcontroller.

### Claim 12 (depends on 9)

The dispensing system of claim 9, wherein the control system comprises an application-specific integrated circuit (ASIC).

### Claim 13 (depends on 9)

The dispensing system of claim 9, wherein the logic controller does not inhibit the additional quantity of the material from being dispensed from the container at a third time after the predetermined time period based upon the sensor detecting the presence of the user in proximity to the dispensing system at the second time.

### Claim 14 (depends on 9)

The dispensing system of claim 9, wherein the sensor comprises at least one of a sonar sensor or a laser sensor.

### Claim 15 (depends on 9)

The dispensing system of claim 9, comprising a housing within which the container is housed.

### Claim 16 (depends on 15)

The dispensing system of claim 15, wherein the control system is housed within the housing.

### Claim 17 (depends on 16)

The dispensing system of claim 16, wherein the sensor is housed within the housing.

### Claim 18 (depends on 17)

The dispensing system of claim 17, wherein the material comprises a cleaning material.

### Claim 19

A method of dispensing a material comprising:
detecting a presence of a user in proximity to a dispensing system at a first time;
dispensing the material such that at least some of the material is dispensed from a container of the dispensing system at the first time;
programming a logic controller coupled to the container to limit a subsequent dispense event from occurring within a predetermined time period;
detecting the presence of the user in proximity to the dispensing system at a second time within the predetermined time period after the first time and after the dispensing at the first time is complete; and
delaying the subsequent dispense event such that no additional quantity of the material is dispensed from the container at the second time and during the predetermined time period, wherein:
detecting the presence of the user comprises using a sensor comprising at least one of a capacitive sensor, an inductive sensor, a microwave sensor, an optical sensor, a sonar sensor, or a laser sensor.

### Claim 20 (depends on 19)

The method of claim 19, comprising:
enabling the subsequent dispense event after the predetermined time period.
