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.

Abstract: A system for diagnostic analysis of a toilet over time intervals comprises a processor operable to receive a distance measurement from a sensor over a network. The processor is operable to determine an instance of a decrease in a water level in a toilet tank based on a comparison of the received distance measurement to a setpoint and to determine a plurality of instances of the decrease in the water level within a period of time. The processor is operable to calculate a ratio of the determined number of the plurality of instances of the decrease in the water level to a number of instances wherein a door changes from a first position to a second position. The processor is operable to compare the calculated ratio to a threshold ratio and to send an alert to a user device when the calculated ratio is less than the threshold ratio.

Abstract: A system includes a door sensor that provides a status of whether a door of a refrigeration system is open or closed, a temperature sensor that measures a temperature of a food compartment of the refrigeration system, a power sensor that measures an amount of power consumed by the refrigeration system, and a compressor sensor that provides acoustic data about a compressor of the refrigeration system. The system further includes a remote computing system configured to send an alert indicating that the refrigeration system needs servicing when the temperature of the food compartment of the refrigeration system is determined to be above a predetermined temperature while: the door of the refrigeration system is closed, the amount of power consumed by the refrigeration system is within a predetermined power range, and acoustic signals of the compressor of the refrigeration system are within a predetermined acoustic range.

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.
