Latest Patents

One of Roos's latest patents is the "Lodged Debris Detector for a Particle Analyzer." This invention is designed for use in particle counters, such as blood cell counters of the COULTER type. The detector operates by generating a voltage pulse when a particle or transient debris passes through its sensing orifice. In contrast, when debris lodges against the orifice, a direct current (d.c.) voltage shift occurs. The voltage is capacitively coupled to an amplifier, and the output is integrated to provide a signal when the integrated voltage exceeds a reference level. This innovative design includes a delay circuit that ensures accurate detection of lodged debris, thereby enhancing the reliability of particle analysis.

Another significant invention by Roos is the "Pulse Amplifying System." This amplifier circuit features an input circuit of resistance and capacitance that is a.c. coupled to a pulse source. The feedback circuit also consists of resistance and capacitance. By ensuring that the RC time constants of both circuits are approximately equal, Roos's design guarantees an output pulse with a flat base line, free from undershoot or overshoot. This advancement is crucial for maintaining the integrity of pulse signals in various applications.
