Abstract: A method for determining the number of cups housed within a cup dispenser includes measuring, via a first sensor coupled to a plunger, and a distance from the plunger to a second end of the dispenser body. The dispenser comprises a body configured to hold a stack of cups, a spring, and a plunger that biases the stack toward a discharge opening. The measured distance is received and used to calculate a measure of the cup count. Based on this determination, the method compares the count to a predefined threshold. If the count is below the threshold, the method transmits an alert for display on a user device. This approach enables automated monitoring of cup inventory, reducing manual checks and supporting timely replenishment.

Abstract: A system for providing a measure of a number of cups housed within a cup dispenser includes a sensor and a computing system. The cup dispenser includes a body configured to house a stack of cups, and a plunger configured to engage a first cup of the stack of cups and to bias the stack of cups toward a discharge opening defined by a first end of the body. The sensor is coupled to the plunger and is configured to measure a distance from the plunger to a second end of the body, and to transmit the measured distance across a network. The computing system receives the measured distance from the network, and determines, based on the measured distance, the measure of the number of cups housed within the cup dispenser. In response to determining that the number of cups is less than the threshold, the system transmits an alert.

Abstract: A system includes one or more memory units and a processor. The processor is configured to receive, from a food temperature probe, a first temperature associated with a first food item. The processor is further configured to receive, from the food temperature probe, a second temperature associated with a second food item. The processor is further configured to receive, from the food temperature probe, a third temperature that was measured by the food temperature probe after measuring the first temperature but before measuring the second temperature, the third temperature associated with a cleaning of the food temperature probe. The processor is further configured to send an alert for display on a user device when the third temperature is greater than the cleaning threshold temperature.

Abstract: A system for determining an ambient concentration of compositions for bathroom cleaning comprises a processor operable to receive a concentration measurement from a sensor over a network within a first period of time. The processor is operable to compare the received concentration measurement to a first threshold and to a second threshold greater than the first threshold. The processor is operable to instruct a memory communicatively coupled to the processor to store an indication that a bathroom was cleaned in response to a determination that the received concentration measurement is greater than the first threshold and less than the second threshold. The processor is operable to send an alert for display on a user device indicating either that the sensor has been tampered or that a spill event has occurred in response to a determination that the received concentration measurement is greater than the second threshold.

Abstract: A system includes a sensor and a computing system. The sensor is coupled to a syrup line of the beverage dispenser and is configured to measure a pressure within the line. The syrup line is coupled at a first end to a syrup bag and at a second end to a pump configured to pump syrup from the syrup bag to an outlet of the beverage dispenser. The pump is operated using pressurized gas and generates a pressure corresponding to the pressure of the gas within the syrup line when both the syrup bag is full and the outlet of the beverage dispenser is closed. The sensor transmits a measured pressure to the computing system. The computing system determines that the measured pressure is less than a threshold pressure. In response, the processor transmits an alert for display on a user device, which identifies the syrup bag for replacement.

Abstract: A system includes first and second sensors, and a computing system. The first sensor measures a first property of a first piece of equipment, and the second sensor measures a second property of a second piece of equipment. The computing system includes a processor and memory, which stores a condition that depends on both the first property and the second property. Satisfaction of the condition indicates that maintenance of the first piece of equipment should be prioritized over maintenance of the second piece of equipment. The processor receives the measured first property and the measured second property. In response to determining, based on the measured first and second properties, that the third condition is satisfied, transmits an alert for display on a user device. The alert indicates that maintenance of the first piece of equipment has a higher priority than maintenance of the second piece of equipment.
