  • Patent number: 12082601
    Abstract: A food processing facility having application apparatus located within the interior space of the food processing facility for applying a PAA solution to food, a mixing container for containing a PAA solution having a PAA solution concentration, with the mixing container connected to the application apparatus for delivering the PAA solution to the application apparatus, and a PAA gas sensor, located within the interior space, for sensing a PAA airborne concentration. An actuation control system connected to the PAA gas sensor is adapted to receive a measure of the PAA airborne concentration and, when the measure of the PAA airborne concentration exceeds a reference value, changes one or more of the PAA solution concentration of the PAA solution in the mixing container, the flow rate of the fresh air ventilation system, and the flow rate of the exhaust air system.

  • Patent number: 11629865
    Abstract: An apparatus for dehumidifying ambient atmospheric air includes a first air path and a second air path. A heat exchanger system transfers at least a portion of radiated thermal energy to air drawn along the first air path to heat the air in the first air path and transfers at least a portion of the thermal energy from exhaust gas to air drawn along the first air path to heat the air in the first air path. The first air path connects the ambient atmosphere to a reactivation air outlet through the heat exchanger system and a desiccant in a second moisturized state, and the second air path connects the ambient atmosphere to a dried air outlet through the desiccant in a first dried state.

  • Publication number: 20200217526
    Abstract: An apparatus for dehumidifying ambient atmospheric air comprising an enclosure assembly configured to define a first air path and a second air path, and containing a moisture-absorbing desiccant having a first dried state and a second moisturized state. The apparatus features a heat exchanger system including first means for (a) receiving radiated thermal energy from an internal combustion engine, and (b) transferring at least a portion of the radiated thermal energy to air drawn along the first air path to heat the air in the first air path; and second means for (a) receiving exhaust gas containing thermal energy from an internal combustion engine, and (b) transferring at least a portion of the thermal energy from the exhaust gas to air drawn along the first air path to heat the air in the first air path.

  • Publication number: 20070089093
    Abstract: A system and method for determining software maturity is disclosed. The method may include building an uncensored belief distribution from a set of observed test data, building a belief distribution based on one or more improvement factors, convoluting the uncensored belief distribution with the belief distribution on improvement factors to form a joined-censored-belief distribution, and translating the joint belief distribution into an a priori belief distribution to assess a level of software maturity.
