Latest Patents
One of Craig's latest inventions is the Precision Time Duration Detector. This device is designed to determine whether the time duration between a positive and a negative peak of a waveform is greater or less than a predetermined time interval. The detector includes a delay line that delays the waveform by the predetermined time interval. It features a peak detector of a first polarity that detects the first occurring peak of the waveform, responding to the delayed waveform to provide a signal upon its occurrence. Additionally, a peak detector of a second polarity detects the second occurring peak of the waveform, responding to the undelayed waveform. A time sequence comparator then provides output indications based on the timing of these signals.
