Abstract: Antimicrobial compositions including at least one acid and at least one anionic surfactant are provided. In particular, food contact antimicrobial compositions including at least one acid and at least one anionic surfactant provide a no-rinse compositions efficacious against Norovirus, having acceptable use solution pH that do not require use of personal protective equipment (PPE), are surface compatible and do not leave residues on treated surfaces are provided. Methods of cleaning a surface with the compositions are also provided.

Abstract: Antimicrobial compositions including at least one acid and at least one anionic surfactant are provided. In particular, food contact antimicrobial compositions including at least one acid and at least one anionic surfactant provide efficacious virucidal activity, including against Norovirus, having acceptable use solution pH that do not require use of personal protective equipment (PPE), are surface compatible and do not leave residues on treated surfaces. Methods of cleaning a surface with the compositions are also provided and may beneficially eliminate the need to rinse the antimicrobial compositions after use.

Abstract: A system and method is presented for awarding content to users of mobile devices for attending events, appearing at locations, or viewing audiovisual content. One embodiment also automatically alters the configuration of mobile devices, which is particularly useful in movie theaters. An application on the device recognizes an audible signal provided at the location or in the audiovisual content. The signal can also be used to unlock content. In this way, desired content is available only when the user has attended an event such as an event sponsored by the content creator. The content can relate to the event, and can be synchronized to the event. The signal can also trigger an application or unlock content at a store location. For example, a scavenger hunt can be guided by an application on the mobile device.
