Latest Patents
One of O'Brien's latest patents is titled "Geometry for pulsed acoustic measurements of particle size." This innovative apparatus is designed to make pulsed acoustic measurements to determine particle size in samples such as colloids. The apparatus includes two electrodes between which an electric voltage is applied to the sample in short pulses. The applied voltage generates an acoustic signal, such as a sound wave, in the sample, which is detected with a transducer after the wave has passed through a delay element. The delay element introduces a time delay between the application of the voltage pulse and the sound wave reaching the transducer, allowing for the isolation of the received wave's signal from any signal generated in the transducer by the applied voltage. The arrangement of the delay element and the transducer is designed to deflect any reflections of the sound wave from the sidewalls of the delay element away from the transducer, thereby reducing interference, particularly at low frequencies.
Another significant patent by O'Brien focuses on "Particle size and charge measurement in multi-component colloids." This work further emphasizes his expertise in the field of colloidal dynamics.
