  • Patent number: 9491011
    Abstract: A signaling system supports main and auxiliary communication channels between integrated circuits in the same direction over a single link. An equalizing transmitter applies appropriate filter coefficients to minimize the impact of intersymbol interference when transmitting the main data over a communication channel. The transmitter modulates at least one of the filter coefficients with the auxiliary data to induce apparent ISI in the transmitted signal. A main receiver ignores the apparent ISI to recover the main data, while an auxiliary receiver detects and demodulates the apparent ISI to recover the auxiliary data. The auxiliary data may be encoded using spread-spectrum techniques to reduce the impact of the auxiliary data on the main data.

  • Patent number: 9205089
    Abstract: Layer processing for pharmaceuticals, and related systems, methods, and articles are generally described. In some embodiments, ingestible pharmaceutical products (e.g., tablets) can be formed by processing one or more layers containing a pharmaceutically active composition. For example, at least one layer containing a pharmaceutically active composition can be manipulated (e.g., folded, rolled, stacked, etc.) such that the average thickness of the product formed by the manipulation is at least about two times the average thickness of the portions of the layer(s) used to form the product. In some embodiments, after the layer is manipulated, it can be processed (e.g., cut, coated, etc.) to form a final product such as, for example, a tablet.
