  • Publication number: 20170290342
    Abstract: Embodiments disclosed herein provide methods for decontaminating food contact surfaces using a fine spray/mist that comprise an antimicrobial composition comprising an organic acid and an organic citrus extract. The spray application reduces the microbiological populations on the surface of food contact surfaces, including potential pathogens, thereby reducing cross-contamination and improving food safety. The composition described herein can be use to target a number of microbiological pathogens, including L. monocytogenes, which is a known cross-contaminant in retail environments such as deli counters and slicers due to its ability to grow at refrigerated temperatures and moist environments making it a known cause of post-processing contamination of ready-to-eat food products.

  • Publication number: 20170203657
    Abstract: The invention relates to method of detecting an arrangement having a primary unit of an inductive power transfer system and/or a secondary unit of the inductive power transfer system. The method including: using a detector device to detect the arrangement, the detector device having at least one electrical conductor, determining at least one electrical property of the detector device and generating determination results consisting of a determination result for each of different regions of the arrangement, and comparing the determination results with existing information about the arrangement to be detected. The existing information includes information about expected values for the different regions of the arrangement, thereby generating a comparison result, and deciding from the comparison result whether the determination results indicate that the detector device has detected the arrangement as expected.

  • Publication number: 20160227797
    Abstract: Methods of high pressure processing of food products are provided. The methods can include adding a secondary inhibitor to the food product to prevent or slow the growth of pathogenic microorganisms and/or to prevent or slow the growth of spoilage microorganisms. The methods can increase the shelf life and/or the usable life of ready-to-eat food products. Exemplary food products include ready-to-eat deli style meats such as beef, turkey, or ham products. The secondary inhibitor can be an organic acid or consumable salt thereof. In some embodiments the secondary inhibitor is acetic acid, e.g. vinegar. High pressure processed food products are also provided. The food products can have a longer shelf life, a longer usable life, and can be safer for human consumption that conventional high pressure processed food products.

  • Patent number: 7668641
    Abstract: There is described a method for determination of an application time for a tank ventilation on an internal combustion engine. An excessive enrichment of the air/fuel mixture can be avoided by means of a timely application of injection correction as result of the tank ventilation. According to said method, a threshold value comparison is carried out for a modified lambda control deviation, made up of the lambda control deviation and a pseudo lambda control deviation, whereby the pseudo lambda control deviation depends on the deviation of the lambda values from a given lambda set value.
