  • Patent number: 7881894
    Abstract: One delay circuit is inserted in open loop inside a clock recovery circuit for improving the accuracy of clock recovery. One oscillator signal ?(0) to ?(2i?1) is provided with a basic Step of Time. A rational number of Step of Time corresponding to a bit-duration is measured inside a received flow of bits. The oscillator signal ?(0) to j(2i?1) is transformed into a clock signal CK having active edges of said clock signal in phase with at least one oscillator signal ?(0) to ?(2i?1), two consecutive active edges being separated by a time duration proportional to the integer part of the number of Step of Time. A time delay is computed proportional to the fractional part of the number of Step of Time. The next active edge of the clock signal CK is delayed of said computed delay.

  • Patent number: 7685059
    Abstract: A method and system exchanges assets defined as digital automated equities which are objects instantiated with attributes of an asset. Digital automated equities are registered on a common system exchange as offeror mediary objects and matched by comparing their attributes. Capital exchange offer objects define desired matches by identifying a digital automated equity associated with an exchange offer, a exchange price for the exchange and one or more conditions associated with the exchange. A match use case compares attributes of capital exchange offers to determine matches based on the closeness of the capital exchange offers and a negotiate transaction use case supports communication between owners associated with close capital exchange offers to alter attributes in response to a match. Once a transaction is complete, a settle transaction use case exchanges the digital automated equities.
