  • Patent number: 11186794
    Abstract: A hybrid fuel grain is a solid homogenous mixture consisting of paraffin, thermoplastic adhesive, and black dye. A homogenous mixture of the three ingredients is heated in a preheated cast. The cast with the homogenous mixture therein in is placed in an oven. The temperature of the oven is reduced to a selected ambient temperature in accordance with a cooling schedule that comprises a two-step cooling process repeated until the selected ambient temperature is achieved.

  • Patent number: 11133854
    Abstract: Digital predistortion (DPD) arrangements that use coding to differentiate between contributions from individual power amplifiers (PAs) is disclosed. When used with a phased antenna array having N antenna elements and N corresponding PAs, the arrangements may sequentially apply N codes to input signals provided to N PAs. Each code is a vector having N elements, where each element corresponds to a different PA in that the element is a complex gain applied to an input signal for the PA. Together, the N codes may be arranged as N rows or N columns of a matrix P. The disclosed arrangements may generate N feedback signals by applying the matrix P to a signal generated by a probe antenna element sensing wireless RF signals transmitted by the N antenna elements, and to update DPD coefficients based on the N feedback signals. The N codes may be either orthogonal or non-orthogonal.
