Latest Patents

One of his latest patents is focused on practical implementations for ion mobility sensors. This system is designed to signal the presence of selected ion species in a gaseous sample. It features a unidirectional field provided between first and second electrodes positioned a selected distance apart. An ionization source generates ions in the sensor, and a trigger controller allows ions to enter the region between the electrodes at a specific time. The ions then arrive at the second electrode, where a transimpedance amplifier converts the ion charges to voltage signals. The presence of selected ion species is determined by circuitry activated by the trigger controller. The species can be analyzed by directing the amplifier output to an analog to digital converter and then to a digital signal processor. Alternatively, a logic pulse representing a selected ion species can be generated when the amplifier output exceeds a preset value, triggering an alarm signal when coincident with a logic pulse representing the species' travel time.

Another significant patent by Davies is a hybrid electronic-fiber optic system for phased array antennas. This improved radar system incorporates a plurality of bias binary fiber optic delay lines connected between the transmit/receive cells and signal processing means. Additionally, electronic binary delay lines are integrated to enhance the system's performance.
