Abstract: A package for protecting a light sensitive material is disclosed. The package includes an optical film including a plurality of polymeric layers. For a substantially normally incident light, an optical transmittance of the optical film versus wavelength includes a band edge separating a first wavelength range including at least wavelengths from about 360 nm to about 400 nm from a second wavelength range including at least wavelengths from about 520 nm to about 680 nm. The optical film has an average optical transmittance of less than about 15% in the first wavelength range and an average optical transmittance of greater than about 70% in the second wavelength range.

Abstract: A non-transitory computer readable storage medium has instructions executed by a processor to collect keystroke data of a user for a designated time period. A number of distinct keys is derived from the keystroke data. A maximum character frequency is derived from the keystroke data. Digital gaming activity is selectively designated based upon the number of distinct keys and the maximum character frequency.
