  • Patent number: 8311855
    Abstract: The system and method of the invention describes a unique approach to gathering patient treatment information in summary form from a universe of health care providers, each using any form of patient information management; converting that information to pointers that can be searched by a healthcare provider before or during treatment to determine if further information needs to be acquired from the original provider; and a variety of methods to provide access to detailed healthcare treatment and diagnosis information from the original healthcare provider through an access and display method provided by the healthcare provider housing the records, if available. The system and method envisages one or more providers of repository services, each offering various ways for healthcare providers to update and maintain summary information, and each providing for continual exchange of information among them to ensure complete access to all available information.

  • Patent number: 8126075
    Abstract: A system and method for encoding data for transmission over a telecommunications network. The system and method involve embedding a control data block (Ik0) within a plurality of real data blocks (IN0). Preferably, real data in the real data blocks (INO) is convoluted with at least some of the control data in the control data block (Ik0) For example, each entry in each real data block (INO) may be phase convoluted with phase angle of the corresponding entry in the control block using an encoding module. Once this is done, the real data in the real data blocks and additionally the control data block in the control block is modulated with every sub carrier.
