Apparatus and methods for hygiene monitoring in restaurants and grocery superstores
First Claim
1. A hygiene monitoring system for restaurants or grocery stores, comprising:
- One or more temperature sensors installed on or inside restaurant appliances;
A monitoring unit located in the vicinity or remote location;
An internet of things (IoT) gateway where data from sensors is received through a wireless link, andretransmitted over a second wireless communication link to the monitoring unit;
wherein the temperature sensor has a memory chip and a wireless transceiver attached to it, andstores a unique IP address; and
wherein the said monitoring unit compares the received value of the temperature of each appliance with an acceptable range defined for that appliance,and display feedback if the temperature falls beyond that range.

Abstract
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.

11. A hygiene monitoring system for restaurants or grocery stores comprising:
-
One or more interface to the appliances microcontroller units; A monitoring unit located in the vicinity or remote location; An internet of things (IoT) gateway where data from interfaces is received through a wireless link, and retransmitted over a second wireless communication link to the monitoring unit; wherein the interface can read the internal temperature of appliances, has a memory and a wireless transceiver attached to it, and stores a unique IP address; and wherein the said monitoring unit compares the received value of the temperature of each appliance with an acceptable range defined for that appliance, and display feedback if the temperature falls beyond that range.
