A system for use in determining a capacity of a storage bin. The system includes a plurality of sensors positioned within the storage bin. Each sensor is configured to determine a used capacity within a portion of the storage bin, and generate a voltage output based on the determined used capacity, wherein the plurality of sensors is configured to generate an aggregate voltage output based on the voltage output of each sensor. A controller is in communication with the plurality of sensors. The controller is configured to receive the aggregate voltage output from the plurality of sensors, determine a minimum voltage output and a maximum voltage output of the plurality of sensors, and determine a total used capacity of the storage bin as a function of the aggregate voltage output, the minimum voltage output, and the maximum voltage output.

Systems and methods of determining a capacity of storage bins

An occupancy detection system and method for an enclosed space includes a door sensor operatively coupled to a door of the enclosed space. The door sensor is configured to output a door sensor signal that indicates a status of the door. At least one presence sensor that is configured to output at least one presence sensor signal that indicates an occupancy status of the enclosed space. An occupancy detection control unit is in communication with the door sensor and the at least one presence sensor. The occupancy detection control unit is configured to receive the door sensor signal and the presence sensor signal(s). The occupancy detection control unit is configured to determine an occupancy status of the enclosed space based on the door sensor signal and the presence sensor signal(s).

Enclosed space occupancy detection systems and methods

A method of localizing an object is provided. The method comprises deactivating a wireless system in a defined zone and then activating a wireless data concentrator located in the defined zone, wherein the wireless data concentrator is electrically isolated from the wireless system. The wireless system is activated, wherein the wireless system is electrically coupled to a circuit breaker with a known location in the defined zone. A signal from the wireless system is received at the wireless data concentrator. The distance of the wireless system from the wireless data concentrator is determined based on the signal, and a location is assigned to the wireless system within the defined zone based on the distance of the wireless system from the wireless data concentrator and the known location of the circuit breaker in the defined zone.

An occupancy detection system and method for a lavatory includes a door sensor operatively coupled to a door of the lavatory. The door sensor is configured to output a door sensor signal that indicates a status of the door. At least one presence sensor that is configured to output at least one presence sensor signal that indicates an occupancy status of the lavatory. An occupancy detection control unit is in communication with the door sensor and the at least one presence sensor. The occupancy detection control unit is configured to receive the door sensor signal and the presence sensor signal(s). The occupancy detection control unit is configured to determine an occupancy status of the lavatory based on the door sensor signal and the presence sensor signal(s).
