  • Publication number: 20170034131
    Abstract: The present invention provides for a hybrid encryption and decryption apparatus using elements of object-related encryption. The system utilizes a one time pad algorithm and allows for encryption of any digital data, including but not limited to text, picture, audio and video by using an arbitrary object as an information carrier enabling the creation of encryption keys of non-restrained length. Encryption keys are dynamically created and synchronized for all session users and exist only within the session without the need to be pre-defined, stored or archived unless archiving is mandated by user workflows outside the system. Synchronization is based on the exchange of both trivial and useful information bundled in information containers that can be of a fixed or variable length.

  • Patent number: 8323207
    Abstract: An apparatus for the measurement of exhaled respiratory gas temperature during free voluntary tidal breathing, comprises a housing 1 defining a chamber, an air inlet 2 for receiving a stream of exhaled respiratory gas and an air outlet 4 for permitting escape of exhaled respiratory gas from the chamber to outside of the housing. A tube having inner and outer surfaces, is located within the housing and extends from the air inlet into the chamber provides a passageway through which the stream of exhaled respiratory gas may travel from the air inlet in to the chamber. A temperature sensor 6 is located within the housing for measuring the temperature of exhaled respiratory gas.
