  • Lateral error correction for time-critical multicast
    Patent number: 7532621
    Abstract: A system and method for providing a low-latency reliable multicast protocol designed for time-critical clustered applications. Internet Protocol (IP) multicast is used to transmit data and recovers from packet loss in end-hosts using a repair mechanism involving the exchange of XOR repairs between receivers and across groups. The system and method of the present invention can be embodied in a scalable, reliable and fast multicast primitive that can be layered under high-level abstractions such as publish-subscribe, group communication and replicated service/object infrastructures.
    Type: Grant

  • Regulated power supply with auto-transformer output and direct current feedback
    Patent number: 4107620
    Abstract: A bipolar regulated power supply employing an autotransformer to couple the output to the load is provided with a direct current feedback connected directly across the load. In this way losses in the transformer and leads connecting to the load are compensated for and direct current is eliminated from the output transformer when the input is ac coupled.
