A system for generating an alert in case of a social distancing breach in a facility including a first device and second device, each including a processor and a memory. The memory stores executable instructions that, when executed by the processor, facilitate performance of operations. The operations including receiving a first beacon signal from a second device and determining that a first condition associated with a payload of the first beacon signal is satisfied, determining that a second condition associated with a distance between the first device and the second device is satisfied. The operations further comprising generating an alert related to a social distancing warning in response to the first condition and the second condition being satisfied and in response to at least one of the first condition or second condition not being satisfied, not generating the alert.

One or more computing devices, systems, and/or methods for determining a time-length of an action are provided. For example, a first event may be detected. Responsive to detecting the first event, a first inquiry may be transmitted in a first direction, using a first device. The first inquiry may be received by a second device. Responsive to receiving the first inquiry, a first reply data packet, comprising an identification number associated with the second device, may be transmitted, using the second device, to the first device. A second event may be detected. Responsive to detecting the second event, a second inquiry may be transmitted in a second direction, using a third device. The second inquiry may be received by the second device. Responsive to receiving the second inquiry, a second reply data packet, comprising the identification number, may be transmitted, using the second device, to the third device.

A power management system for a dispenser that includes a passive infrared radiation sensor arranged along the dispenser and configured to detect infrared radiation emitted by one or more users within a prescribed detection range, area, or zone of the dispenser. When the passive infrared radiation sensor does not capture infrared radiation within the prescribed detection range, area, or zone, the dispenser is placed in a low power state with the passive infrared sensor remaining connected to a power source and a controller, a dispensing mechanism, and/or the proximity sensor being disconnected from the power source. Other aspects also are described.

A system and method are provided for improving product usage prior to refill of product dispensers in service areas that include a plurality of such dispensers. Via a sensor configured with each of the product dispensers and a control system in communication with the sensors, a product level or amount condition of product in each dispenser is detected. Based on the information from the sensors, a visual or audio message is generated and transmitted to the patron that encourages the patron to use a first product dispenser that has a greater product fill amount as compared to a second product dispenser in the same or a different service area.

This disclosure enables various technologies for analyzing behaviors of objects or with respect to objects based on stereo imageries thereof. For example, such analysis may be useful in enforcement of certain actions by objects or with respect to objects, surveillance of objects or with respect to objects, or other situations involving analyzing behaviors of objects or with respect to objects.

Systems and methods for tracking, locating, identifying, or mapping movements of persons or personnel within a facility may include badges carried by individuals throughout the facility. These badges can each include a transmitter configured to transmit signals including signature information identifying the badges and also identifying codes of each signal transmitted. In addition, a plurality of dispensers can be positioned at selected locations of the facility and can include receivers that receive the signals transmitted by the transmitters of the badges. These receivers also can be configured to transmit information related to the received signals to one or more processors configured to identify each badge from which signals are received based upon the signature information and also to determine the proximity, range, distance, or zone between the badge identified and the receivers.

A system may monitor usage of a cleaning chemical and indicate when the chemical has expired and needs to be replaced. In some examples, the system includes a reservoir containing the chemical and a sensor associated with the reservoir that can detect user interaction with the chemical in the reservoir. The system may track an amount of time until the chemical in the reservoir is deemed to have expired and provide a user alert indicating expiration of the chemical. The system can control the amount of time remaining until the chemical is deemed to have expired based on the detected addition of the object to the reservoir.

Among other things, systems and methods include a first sensor configured to detect operation of the sink; a second sensor configured to detect personal characteristics of a person operating the sink.

Exemplary embodiments of methods and devices for obtaining more accurate hand hygiene compliance metrics are disclosed herein. An exemplary device or badge for a hygiene compliance system includes a housing; a processor located in the housing; memory in circuit communication with the processor; wireless communication circuitry in circuit communication with the processor; and an additional time input in circuit communication with the processor.
