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.

An object of the invention is to improve communication quality in a power storage management system.

The above-mentioned problem may be solved by the following one solution. When a communication error where transmission, reception, or both transmission and reception of a signal is not allowed occurs between one or a plurality of a plurality of information acquisition devices that acquires states of a plurality of power storage cells and an information collection device that communicates with the plurality of information acquisition devices in a time-division manner, and collects information related to the states of the plurality of power storage cells acquired by the plurality of respective information acquisition devices, a process for resolving a communication error is executed by putting all the plurality of information acquisition devices in a state in which communication with the information collection device is allowed at all times. Here, the plurality of information acquisition devices is in a state in which communication with the information collection device is allowed in a first period in which the plurality of information acquisition devices communicates with the information collection device, and is in a state in which the state, in which communication with the information collection device is allowed, is canceled in a second period in which other information acquisition devices communicate with the information collection device in a relation of n to 1 (n is a positive natural number indicating the number of communication channels of the information collection device).

A system and method for transmission of a signal for a powered assistive device has a sensor node with a wireless transmitter adapted for digitally transmitting a transmitted signal, the sensor node adapted for receiving and monitoring a sensor signal from a sensor attached to a user, and a master node with a controller and a wireless receiver for receiving the transmitted signal from the wireless transmitter. The master node processes the transmitted signal and communicates a control signal to the powered assistive device. The wireless transmitter transmits the transmitted signal at a first rate when the wireless transmitter adapted to transmit the transmitted signal at a first rate when the sensor signal is indicative of the rest state and to transmit the transmitted signal at a second rate when the sensor signal is indicative of the active state, the second rate being greater than the first rate.

A hydrant apparatus may be employed to monitor a water distribution system, and may include a sensor, a processor, and a local clock source. The apparatus may wake from a low power mode to a sensing mode, receive the sensor data, associate the sensor data with a first local clock time, and return the apparatus to the low power mode from the sensing mode. The apparatus may subsequently wake to an operational mode, determine a second local clock time subsequent to the first local clock time, associate an external clock time with the second local clock time, determine an offset for the received sensor data based on the first local clock time and the association between the second local clock time and the external clock time, and transmit the sensor data and the offset to an external monitoring system.

An electronic system for monitoring a physical parameter includes an ADM comprising an accumulation mode sensor for measuring the physical parameter by generating electrical energy associated with the physical parameter in response to a surrounding condition, and an energy storing device coupled to the accumulation mode sensor for accumulatively storing the generated electrical energy; a power source; and an SoC coupling with the ADM and the power source, configured such that the stored electrical energy is monitored, and when the stored electrical energy is equal to or greater than a pre-defined threshold, a wake-up event is generated to trigger the SoC to operates in a run mode in which the physical parameter is wirelessly transmitted to a receiver and the stored electrical energy in the energy storing device is discharged, and then the SoC returns to a sleep mode in which a minimal power is consumed.

A monitor and control system and a method of monitoring and controlling an onboard system of an assembly includes one or more of a plurality of sensors detects whether an event occurred in the onboard system. The sensors communicate with a master controller when the master controller is in a nominal mode in which the master controller is powered on to actively monitor the sensors, and includes a sleep mode in which the master controller is powered off and does not monitor the sensors when in the sleep mode. An agent controller monitors the sensors when the master controller is in the sleep mode. One or more of the sensors signal the agent controller that the event has occurred. The agent controller signals the master controller to awaken from the sleep mode in response to the one or more of the sensors signaling the agent controller of the event.

A sensing system generates location signals indicative of where an electrically-powered, mobile device is in a venue. A control system determines that the mobile device is at rest when the location signals are substantially the same for a predetermined period of time, processes the location signals to determine an accurate, current location of the mobile device in the venue when the mobile device is determined to be at rest, and controls the mobile device when determined to be at rest to operate in a low power mode in which the average electrical power consumption of the mobile device is reduced.
