Various examples are provided of low power, rapid response on-device heaters and methods of calibrating the device within a linear operating region, which is reached and maintained through control of the on-device heater. A system to be calibrated includes a sensor to measure the temperature and relative humidity of the system, a heater coupled to the sensor, a heater controller coupled to the heater to control the heater to heat the system, and a processor coupled to the sensor and the heater controller. The processor controls the heater based on temperature measured by the sensor to perform a calibration process for the system including calculating a calibration factor, and to determine whether to abort the calibration process based on relative humidity measured by the sensor indicating that the system is outside the linear operating region.

A method for controlling an environment within a sterilizer device is disclosed. The method includes equipping an interior space of the sterilizer device with an auxiliary device having a temperature sensor, a humidity sensor, a heating element, monitoring temperature within the sterilizer device, receiving, by the sterilization device, information associated with an initiation of a sterilization cycle of the sterilizer device; monitor duration of the sterilization cycle, receiving, by the sterilization device, information associated with an end of a sterilization cycle of the sterilizer device, determining whether a current humidity measurement is above a predefined threshold, and controlling the heating element to an ON operating state when the current humidity measurement is above the predefined threshold.

A cleaning system for cleaning a band circulating in a paper making machine; the system comprising: at least one detecting device configured to detect at least one parameter indicative of the cleaning conditions of the band on at least one portion of the band; at least one cleaning device provided with at least one nozzle to create a jet of a cleaning fluid; the nozzle being arranged so that the jet of cleaning fluid is directed towards the band; a control device configured to regulate the cleaning device on the basis of the at least one parameter indicative of the cleaning of the band.

A system and a method include receiving, by a processor, from environmental sensors, environmental output data measurements. The environmental sensors are located at a site location. An health impact scoring algorithm computes a plurality of health impact scores from the environmental output data measurements. An overall health impact score at the site location is computed from the any of the health impact scores having a lowest value. A machine learning model generates at least one recommendation for remediating at least one verified environmental hazard type. At least one of the overall health impact score, the at least one verified environmental hazard type, or the at least one recommendation are displayed on a computing device. An instruction is sent to environment-controlling equipment located at the site location to change an operational parameter of the environment-controlling equipment to mitigate the at least one verified environmental hazard type.

An arrangement for monitoring an aseptic manufacturing process includes product condition sensors capable of making closely spaced measurements of a product condition such as temperature or humidity. The measurements are made using closely spaced sensors arranged in a linear array on a single probe, which may be used to take measurements at multiple levels within the product. Data from the sensors is transmitted to a data collection point via short range wireless digital communications. The sensors may be used to measure temperature and humidity at a single point. For example, when the sensors are used in pharmaceutical freeze drying, the location of a sublimation front may be calculated for each vial, and the freeze drying process may be controlled using the data.
