  • Patent number: 11916570
    Abstract: The present disclosure generally relates to a codeword format for data storage and to methods and circuits for generating a codeword based on data to be written in memory and extracting data from a codeword read from memory. In an example, an integrated circuit includes a memory system and a controller circuit. The controller circuit is communicatively coupled to the memory system and is configured to: receive multi-bit data; generate a codeword based on the multi-bit data; and transmit to the memory system the codeword for writing to memory. The codeword has a format that includes first bit positions for the multi-bit data, second bit positions for a bitwise inversion of the multi-bit data, a third bit position for an odd parity value, and a fourth bit position for an even parity value. The odd and even parity values indicate an odd and even parity, respectively, of the multi-bit data.

  • Patent number: 8201708
    Abstract: A silo has more than one discharge passage, and each passage has the ability to increase or decrease its respective flow rates. The silo and each portion of the silo that feeds into each individual discharge passage can measure a feature of the solid being dispensed, such as its moisture content or its temperature. A computer controller is then used to take this feedback and adjust the rate of flow from each discharge passage so that the flows from each passage are kept the same despite the variation in moisture, temperature or any other characteristic of the flowing solid. A method to utilize this device is also taught.

  • Publication number: 20080244986
    Abstract: It is known that poorly-flowing solid materials can lead to an inhomogeneous mass flow of the solid across the discharge cross-section of a silo. If the solid in the silo is also heated or cooled the uneven mass flow can lead, for example, to local variations in temperature and/or hence to varying product properties. According to the invention, the above problem may be resolved, whereby a method and a discharge device for a solids silo and a solids silo are disclosed, permitting a controllable solids discharge evenly across the cross-section of the silo. The cross-section of the silo discharge is divided into several, preferably equivalent, partial cross-sections to which a continuously controllable discharge device is connected. The solid flow discharged from the controllable discharge devices can be collected on a continuous conveyor arranged therebelow and removed.
