Latest Patents

Among his latest innovations is the "Shape modulation transmit loop with digital frequency control and method for same." This invention allows for spectral shaping of a digital pulse stream by controlling the slew rate of the transition signal between successive pulses. The loop is created when the digital data stream is fed into an up/down counter, whose output is connected to a programmable memory means, such as RAM or flash memory. The output of the programmable memory serves as the first input to an adder, which drives an accumulator with specified steps. Values corresponding to the desired waveform are stored in a lookup table, which is linked to a digital-to-analog conversion circuit that constructs a sine wave output signal based on the frequency set by the current specified step of the up/down counter.

Another significant patent is the "Self aligning PLL demodulator." This demodulator includes a phase detector that receives a modulated signal and outputs a demodulated signal. The phase detector also receives a reference signal. A programmable voltage circuit outputs an analog voltage, while a reference signal generator responds to the programmable voltage circuit and the demodulated signal, providing the reference signal to the phase detector. A window detect circuit generates an inhibit signal when the demodulated signal is within preselected limits, which is coupled to latch the programmable voltage circuit.
