  • Publication number: 20140101079
    Abstract: A knowledge processing system that guides massive numbers of human agents and artificial agents to define, explore, and develop solutions for complex, problematic situations, that facilitates a seven-step process that proceeds from instance initiation, problem definition, problem exploration, approach selection, solution selection, to a time-sequenced action plan, and enables agents to subsequently modify process outputs and the action plan; a hybrid facilitation system in which machine and human agents jointly select the content and order of process steps and the system prompts that guide the problem-solving process; and an information-overload mitigation system which reduces the amount of information agents are required to process by means of natural language processing and graphical processing algorithms that characterize agent inputs and background materials, and identify, tag, sequester, and eliminate identical content and direct useful content to agent-defined points of application in the process.

  • Patent number: 5703531
    Abstract: Operating on the principle of vector summation, a predistortion linearizer includes a signal divider on one side of a substrate plate that divides a microwave signal into a linear portion and a nonlinear portion. Signal energy on both the nonlinear and linear portions is coupled into two respective slotline transmission lines on the substrate by uniplanar Magic T hybrids. As the signals are transmitted along the slotlines, their relative amplitudes and phases are adjusted to introduce a distortion inverse to that expected in a subsequent amplification. The linear portion and nonlinear portion pass through another pair of baluns. The signals are then combined by an in-phase summation on the same side of the plate as the input signal divider.

  • Patent number: 5668842
    Abstract: A plurality of biphase modulators (42) each modulate a sinusoidal radio frequency signal based upon a corresponding one of a plurality of bits contained in a time-dependent data word. The biphase modulators (42) form a plurality of biphase modulated signals which are communicated to a summing network (40). The summing network (40) contains a plurality of attenuators (44) which attenuate the modulated signals to form a plurality of attenuated signals. The summing network (40) combines the attenuated signals to form a radio frequency signal.

  • Patent number: 5504461
    Abstract: A slotline binary phase shift keyed (BPSK) modulator that is capable of operating at high frequency with relatively low sensitivity to terminating impedance. The slotline BPSK modulator comprises a slotline formed in a conductive layer disposed on a substrate, and a pair of diodes coupled to the conductive layer and disposed across the slotline. An RF carrier input signal is coupled to the slotline using a microstrip-to-coplanar line transition that forms one portion of a balanced transformer. The balanced transformer applies the RF carrier input signal with equal amplitude and 180 degree phase difference to each of the diodes. A modulating baseband signal is injected into the microstrip-to-coplanar line transition through a microstrip line and a lumped element low pass filter coupled to the microstrip-to-coplanar line transition. A direct via hole is provided for coupling a baseband modulating signal from the microstrip-to-coplanar line transition to the diodes.
