With a total of 3 patents to his name, Fields has demonstrated a commitment to innovation and advancement in his area of expertise.
Latest Patents
One of his latest patents is the "Phase Startable Clock Device." This apparatus is designed to generate a phase startable clock signal. It comprises an oscillator that provides a continuous sinusoidal input signal, along with a control signal source that offers a control input signal. This signal transitions between a first state and a second state at a selected time during the signal epoch of the sinusoidal input signal. The device also includes a phase splitter, track and holds, multipliers, and a summation device that operate on the sinusoidal input signal with the control input signal to produce a sinusoidal output signal commencing with a predetermined phase at a predetermined time relative to the transition.
Another significant patent is the "Swept Frequency Domain Reflectometry Enhancement." This improved instrument features an input/output terminal connected to one end of a cable. It converts a radio frequency at the input/output terminal to an intermediate frequency using a swept local frequency. The radio frequency is derived from the swept local frequency and a variable offset frequency. A controller manages the variable offset frequency while monitoring the amplitude of the intermediate frequency. A period counter counts the intermediate frequency at a first maximum response and further counts the offset frequency at a second maximum response. The location of a discontinuity in the cable is calculated from the counted frequencies.
