  • Patent number: 7983867
    Abstract: Systems and methods of processing data generated using multi-gain detectors are disclosed. These systems and methods include separate gain images and separate offset images associated with each dynamic range of a multi-gain detector. These images are applied to multi-gain raw data to generate multi-gain corrected data. Some embodiments of the invention further include systems and methods of generating and using a multi-gain look-up table configured for generating viewable data from multi-gain corrected data. Some embodiments of the invention further include systems and methods of generating a global gain ratio for converting multi-gain data to non-multi-gain data.

  • Patent number: 7840002
    Abstract: Apparati, methods, and computer-readable media for strengthening a one-time pad encryption system. A method embodiment of the present invention comprises the steps of encrypting plaintext (1) with an OTP key (2) in an XOR operation to produce ciphertext (3); and obfuscating the ciphertext (3) with an AutoKey (4) in an XOR operation to produce AutoKeyed ciphertext (5), wherein the AutoKey (4) is a reusable key.
