Abstract: Disclosed are systems, apparatus, and methods for protecting digital media. An exemplary method includes receiving digital media, encrypting the digital media using an encrypted file format to generate an encrypted file, displaying a context menu when the encrypted file is accessed, the context menu including a licensing screen, enabling a user to obtain a license to the digital media using the licensing screen of the context menu, and configuring the encrypted file to enable access to the digital media based on a term of the license.

Abstract: An electrostatic analyzer (ESA) includes a coaxial structure having an outer conductive cylinder, an inner conductive cylinder, and one or more pathways disposed therebetween and extending from a first end to a second end of the coaxial structure. The outer conductive cylinder and the inner conductive cylinder may each be structurally configured to receive a bias voltage for creation of a predetermined electric field therebetween that allows for passage of charged particles with a predetermined energy/charge band along a helical path through the coaxial structure. The ESA may further include an entrance filter on the first end of the coaxial structure that defines a plurality of openings aligned at a predetermined angle thereby limiting one or more fields of view between a pathway through the ESA and the external environment to filter particles, by their trajectory, from entering the pathway for analysis by the ESA.
