Latest Patents

One of Swansen's latest patents is titled "Fast Counting Electronics for Neutron Coincidence Counting." This invention features an amplifier-discriminator designed to output a very short pulse upon receiving an above-threshold input from a detector, such as a .sup.3 He detector. The short pulse output is then stretched to energize a light-emitting diode (LED), providing a visual indication of operation and pulse detection. Additionally, the short pulse is processed digitally and can be ORed with other generated pulses. The final output is fed to a derandomizing buffer, which converts rapidly occurring pulses into synchronized and periodically spaced-apart pulses for accurate counting. The design also allows for the internal and external disabling of each individual channel of amplifier-discriminators in an ORed configuration.

Another significant patent by Swansen is the "Stepping Motor Controller." This invention involves a stepping motor that is microprocessingly controlled by digital circuitry. The circuitry monitors the output of a shaft encoder that is adjustably secured to the stepping motor. It generates a subsequent stepping pulse only after the preceding step has occurred and a fixed delay has expired. The fixed delay is variable in real-time, allowing for smooth and controlled deceleration.
