A handwash monitoring system includes an imaging device and a processor. The processor extracts a hand region corresponding to a hand of a user from an image captured by the imaging device. The processor detects a detergent foam region having a color component designated in advance in the hand region. The processor decides whether a hand-washing motion of the user satisfies a specified condition based on a proportion of the detergent foam region to the hand region.

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 hand washing system, comprising a reagent and water dispensing unit connected to a server. The dispensing unit comprises a personal identification unit, a reagent dispenser, a connection to a water source, one or more sensors for monitoring the handwashing act, and a controller comprising processor and memory for operating the dispensing unit and for storing handwashing data parameters. The server receives and analyzes handwashing data parameters. When an individual approaches the dispensing unit the identification unit identifies the individual, the one or more sensors confirm that the individual's hands are at location apt for receiving reagent from the reagent dispenser and water for at least a predetermined amount of time and the processor sends the server handwashing data parameters.

Discloses is a workstation monitoring system. The system can include a camera configured to capture images and/or video of a workstation. The system can include a monitoring module configured to: receive images and/or video from the camera; identify a surface and a state for the surface, the state including any one or combination of occupied, vacant, clean, dirty, contaminated, attended to, or not attended to; track behavior of an individual, movement of an object, and/or an occurrence for the surface that causes a change in the surface's state; and generate a trigger event signal based on the change in the surface's state.

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.

A camera system for defining an inspection space including one or more cameras placed in proximity to a sink or wash station. The camera system is configured such that points within the defined inspection space are visible and may be recorded, but objects outside the defined inspection space are blurred or invisible. This is accomplished by selecting depth of field or by attaching a computing device that is programmed to not record or save information from parts of the image.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for group identification and monitoring. The methods, systems, and apparatus include actions of determining, using one or more first frames of a video sequence, that two people each of whom is depicted in at least one of the first frames satisfy a grouping criteria that indicates that the two people should be grouped for video analysis, determining, using one or more second frames of the video sequence at least some of which were captured after the one or more first frames and which depict at least one of the two people, that the two people satisfy a degrouping criteria that indicates that the two people should not be grouped for video analysis, determining that a physical distance between the two people violates a distance criteria, and providing an alert that the distance criteria is violated.

Methods, and a hand wash monitoring system for motivating and monitoring hygiene compliance are disclosed. The hand wash monitoring system communicatively connects to Radio-frequency Identification (RFID) readers positioned at a sanitizer unit and a water dispensing unit. The RFID readers detect the presence of a user wearing a RFID badge near the sanitizer unit and the water dispensing unit. Further, the RFID readers detect the usage of the sanitizer unit and the water dispensing unit by the user and communicate the information to the hand wash monitoring system. The hand wash monitoring system includes a display. The hand wash monitoring system displays the status of user's compliance of hand washing and/or hand sanitization on the display to improve hygiene compliance with established protocols.

Methods and systems for monitoring procedural compliance of staff in a facility. A system may include a plurality of sensors positioned adjacent a hand washing station. Each of the plurality of sensors may be configured to provide a corresponding sensor output signal that is indicative of whether a person is washing their hands at the hand washing station or not. A controller may be configured to fuse the sensor output signals from each of two or more of the plurality of sensors and to determine using the fused sensor output signals whether the person has washed their hands at the hand washing station in compliance with one or more predetermined criteria or not. The controller may be further configured to output a notification when the controller has determined that the person has washed their hands at the hand washing station in compliance with the one or more predetermined criteria.

A handling alert apparatus configured to detect a predefined event and output an alert responsive to detecting the predefined event. The handling alert apparatus includes a housing connected to an article of merchandise. The handling alert apparatus includes a handling sensor configured to detect when a customer handles the article of merchandise. Responsive to detecting handling of the article of merchandise, the housing outputs a visual, audible, or wireless notification alert. The alert remains active until an authorized user prepares the article of merchandise for subsequent customer interaction and deactivates the alert by using a wireless controller or manually operating a designated deactivation button or switch.
