Title: Edgar M Litzaw: Innovator in Dispensing Solutions and Digitization
Introduction
Edgar M Litzaw is a notable inventor based in Corte Madera, California. He has made significant contributions to the fields of dispensing solutions and digitization, holding a total of three patents. His innovative designs reflect a commitment to enhancing functionality and efficiency in various applications.
Latest Patents
One of Litzaw's latest patents is a dispenser for dispersing sterile solutions. This device includes a valve that controls the dispensing of sterile solutions from a container. The valve features a solution outlet and an air inlet opening, which is equipped with a filter membrane to ensure that the air entering the container is filtered. When force is applied to the container, the solution outlet opens, preventing the solution from accessing the air inlet. Upon relieving the force, a partial vacuum forms in the container, causing the solution outlet to close and allowing air to be drawn in through the filter membrane.
Another significant patent is the improved polar coordinate digitizer. This device utilizes a cord that extends from a base unit to provide angle measurements while being wrapped around a drum for length measurement. The design minimizes lateral pressure on the cord guide through a low mass pivot arm, with angle sensing achieved via optical photodetector techniques. The system also includes calibration features to enhance accuracy.
