  • Patent number: 12145422
    Abstract: Systems and methods to provide environment control to individual containers of a storage system may include a distribution network including one or more sources, distribution lines, valves, sensors, and storage positions. The distribution network may be operated to provide air flow having desired environment attributes to individual storage positions that include supply and/or return lines and associated valves. Insulated containers having input and/or output lines and associated valves may couple to the distribution network upon placement at the storage positions, thereby providing air flow with desired environment attributes to individual insulated containers and associated items. Further, non-insulated containers may also be placed at the storage positions of the storage system without connecting to the distribution network.

  • Publication number: 20220121735
    Abstract: We propose a method that uses sequence of biometric identities, gestures, voice input, characters, symbols and pictures, for user authentication and verifications. So, user credential would be combination of “What he/she is and what he/she knows”. User can create credential sequence using either same biometric identity or combination of two or more different biometric identity types, plain characters, formatted characters, unformatted symbol, formatted symbol, unformatted picture and formatted picture where any of these credential sub-member may or may not be present in the sequence created as user credential.

  • Publication number: 20200012771
    Abstract: We propose a method that uses sequence of biometric identities, gestures, voice input, characters, symbols and pictures, for user authentication and verifications. So user credential would be combination of “What he/she is and what he/she knows”. Examples of biometric identities are finger prints, toe prints, knee scan, iris scan, palm vein and any other body parts' image or scan that uniquely identifies a person. User may use gestures of same or different types as part of the credential. Examples of characters are alphabets in any language, numbers and special characters like @, #, $, ˜, ! and any other available for input. Examples of Symbols and Picture are emoticons, emoji's, image, photo or drawing. Characters can be plain or formatted using formatting options of color, shading, font styles—bold, italic, underline, strikeout, superscript, subscript, font name, font size and other available formatting options.

  • Patent number: 9536069
    Abstract: We propose a method that uses formatting options of Font, Font Size, Font Color, Shading, Font Style, Font Effects, Font Underline, Character Effects, Picture coloring, as a part of user passwords, credentials, electronic signature, challenge for user authentication and captcha verification. User personalizes user name and or password or text by choosing combination of proposed factors for each character or word in password. Method includes optional time range where user would have different password and factor combinations for each time range. We also propose a method to use these factors for multi-factor authentication where user is required to format given text as per remotely sent instructions. We propose variation of proposed method that would send text and the instruction to format it using different factors through separate communication channels. For user verification, our method asks user to format the given text or given picture as instructed using different formatting options.
