Latest Patents
Dunstan holds a patent for an "Isolation circuit for blood cell counter." This invention involves a particle counter that utilizes a Coulter type aperture and a suction flow path downstream from the aperture. The design features a pair of electrodes on both sides of the aperture, with a current provided from the downstream electrode to the upstream electrode. The voltage across the aperture is monitored to detect the passage of blood cells. Additionally, a grounded electrode is strategically placed in the downstream flow path to isolate the cell counter from external electrical noise signals. An isolated high input impedance amplifier is coupled to provide the monitored voltage to an inserted electrode positioned between the downstream aperture electrode and the grounded panel electrode. This innovative design ensures that no current flows through that portion of the flow path, enhancing the accuracy of the measurements.
