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 detection and reporting device for determining a usage event indicating a use of a piece of hygiene equipment, the detection and reporting device comprising a positioning section that allows determining positional information indicating a position of the detection and reporting device; a sensor section configured to sense over a time span an observable indicating a use of the piece of hygiene equipment and to generate usage event information on the basis of the sensed observable; and a reporting section configured to generate and transmit a message on the basis of said usage event information and on information allowing an association to said positional information.

The present invention relates to an artificial intelligence based smart hand sanitization system (100) for elderly is provided. The system (100) comprises an inlet pipe (102), a liquid chamber (104), a washing model (110), a collection chamber (106), and an outlet pipe (108). The washing model (110) comprises a plurality of sensors (112), a first scanner unit (116), and a plurality of moveable nozzles (114), a second scanner unit (118), a central processing unit (120), and an alert generating unit (122). The smart portable system (100) for hand-wash has a plurality of moveable nozzles (114) to wash the hands of the user without wetting the accessories and cloth of the user. The present invention is a detachable smart portable system (100) for hand wash that can detach from the wall and be re-fixed on the wall according to the user requirement.

A queue analysis apparatus includes an acquisition unit, a first detection unit, and a control unit. The acquisition unit acquires an image of an area of a queue, which is captured by an imaging apparatus. The first detection unit detects persons from the image acquired by the acquisition unit. The control unit controls indications of standby positions of the queue so as to be displayed on a floor of the area of the queue so that a spacing between the indications of the standby positions of the queue is determined based on the persons detected by the first detection unit.

The present invention provides device designed to provide sheets that are disposable and water resistant. The present invention includes a plurality of chairs with numbers, a container, sheets having numbers that match one or more of the plurality of numbers attached to the chairs, a chair transceiver and a container transceiver.

A washroom system and related operations method are provided wherein patrons receive a personalized message or other personalized washroom experience. A washroom facility is configured with a receiver that receives a respective ID signal unique to particular patrons that enter the facility. The unique ID signal is transmitted by a device carried by the patrons. A processor system is in communication with the receiver for receipt of the unique ID signals. The processor system includes a memory with a file associated with each of the unique ID signals, the files containing information on the respective patron associated with the unique ID signal that is retrieved by the processor and used to generate and transmit the personalized message to a broadcast device in the washroom facility.

An illustrative system includes two wearable devices configured to be worn near a jaw on opposite sides of a user's head, each device comprising: at least one microphone, at least two accelerometers, at least one loudspeaker, wherein the system is configured to process data acquired by the accelerometers and by the microphones to: detect chewing, and output an audible notification via the loudspeakers to notify the user to brush the user's teeth after chewing is no longer detected.

One or more techniques and/or systems are provided for personal tracking of hygiene compliance of a user. For example, a mobile device may host a tracking component (e.g., a personal hygiene compliance app deployed on a cell phone or tablet). The tracking component may be configured to establish a communication connection, such as a Bluetooth communication connect, with a hygiene device (e.g., a soap dispenser). The tracking component may generate either a hygiene compliance metric or a non-hygiene compliance metric based upon whether a dispense event notification, indicating compliance by the user with a hygiene opportunity, is received from the hygiene device. In this way, the user may personally track hygiene compliance information based upon automated communication signals shared between the mobile device and the hygiene device.

This disclosure describes methods and apparatus for hygiene monitoring in chain restaurants and grocery superstores. Four sub-systems are introduced to take care of different aspects of hygiene in restaurants. One sub-system uses contactless and in-contact temperature sensors installed on appliances to constantly monitor the temperature of working appliances to be in pre-defined range and use an Internet of Things gateways to transmit the data to remote control unit. The system generate an alert or report if the temperature of the appliances falls beyond the predefined range for more than a specific period of time. Another sub-system use a combination of temperature, humidity, UV and gas detectors to monitor the environment to be unsuitable for growth of fungus and bacteria and alert in case of exposure to harmful material and sun radiation. This sub-system also use an Internet of Things gateways to transmit the data to remote control unit. The third sub-system use a combination of radio frequency tags attached to the staff, RF tag readers and infrared/proximity/motion/microphone/touch sensors installed over the faucet and dispenser to monitor if the staff wash their hands properly after going to the restroom. The forth sub-system automatically generate food expiring label for opened cans and food container based on RF tag worn by the staff. The system generate and print the label whenever the staff gesture their RF tags in front of them and potentially scan the container bar code or select it from a drop-down menu on its touch screen. The last sub-system can also monitor the inventory of opened cans of food in the refrigerator and provide a report or alert when they the time gets close to expiration date.

A Real Time Locating System (RTLS) hygiene management and monitoring system for individuals and companies to manage and monitor the hygiene of their surroundings. For example, the system can be used in conjunction with a cleaning device and can include a locating module, a display module, and a cleanliness monitoring system. The locating module determines a location of the cleaning device in an area and to track movement of the cleaning device within the area. The display module includes a graphical layout of the area. The cleanliness monitoring system generates data representative of a path that the cleaning device has traversed in the area and at least one aspect of cleaning behavior of the device in the area. The display module displays the data representative of the path and the data representative of the at least one aspect of cleaning behavior, and one or both of the path and the at least one aspect of cleaning behavior is color-coded on the display module.
