Latest Patents

One of Cannon's latest patents is titled "Geometry for pulsed acoustic measurements of particle size." This apparatus is designed to make pulsed acoustic measurements to determine particle size in samples, such as colloids. The device utilizes two electrodes between which an electric voltage is applied in short pulses. This voltage generates an acoustic signal in the sample, which is detected by a transducer after passing through a delay element. The delay element introduces a time delay, allowing the received wave's signal to be isolated from any interference caused by the applied voltage. The arrangement of the delay element and transducer minimizes reflections of the sound wave, reducing interference, particularly at low frequencies.

Another significant patent is the "Device for determining the size and charge of colloidal particles." This apparatus determines the particle charge and size distribution of particles in suspensions of arbitrary concentration. It includes a cell for applying an unsteady electric field or mechanical force across the suspension at different frequencies to accelerate the particles. The resulting acoustic wave generated by the electric field or mechanical force is measured, with transducers converting mechanical forces to electrical forces.
