Method for determining the temperature of products transported on the conveyor belt of a cryogenic tunnel, comprising the following steps: —continuously measuring the surface temperature of products travelling on the conveyor belt; —measuring the thickness of a product at the point where the temperature measurement is taken; —performing the following evaluation: a. when the thickness of the product is within a certain range, then the temperature measured for said product is considered to be a reliable value; b. when the thickness of the product is outside the range, then the last temperature value of the measured product is considered to be a reliable value according to paragraph a) above; c. after a determined period of time during which the measured thickness is outside the range, it is concluded that there are no products on the conveyor belt and the temperature measurements are no longer taken into account.

There is provided a method that includes directing one or more infrared cameras at a compaction roller of a composite laying head of a composite layup machine. The one or more infrared cameras are mounted aft of the compaction roller. The method includes applying heat to a substrate by a heater. The heater is mounted forward of the compaction roller. The method further includes using the one or more infrared cameras, to obtain one or more infrared images of the compaction roller, during laying down of one or more composite tows of a composite layup onto the substrate by the compaction roller. The method further includes identifying, based on the one or more infrared images, one or more temperature profiles of the compaction roller, and analyzing identified temperature profiles, to determine one or more of, a layup quality of the composite layup, and a heat history of the composite layup.

The present invention is directed to systems and process for detecting a febrile condition in screening of multiple or large groups of persons for the likelihood of infectious diseases. The system comprises a temperature measurement device having at least a processor, a display, temperature sensor, camera module, and facial recognition software. The display may include a positional overlay. The system further includes a database containing baseline temperatures for a number of persons, including baseline temperatures by age group and by gender. An input device optionally may identify the specific person or provide survey questions to a person to further determine a febrile condition. Based on the baseline temperatures, measured temperature and other characteristics of the person, a febrile condition may be determined. Additionally, the system may include a secondary screening component providing nasal swabbing or saliva testing.
