Latest Patents

One of Richard L. Vigeant's key inventions is the durable high-precision magnetostrictive pump. This pump utilizes a magnetostrictive element that compresses a chamber containing a working fluid when an alternating magnetic field is applied. The design allows for a bellows within the working fluid to be repeatedly compressed, effectively pumping fluid in and out. A significant advantage of this design is that the magnetostrictive element does not directly contact the bellows, which greatly extends the life of the bellows. The pump is equipped with valves to direct fluid flow and can be combined with other pumps in various configurations to create a pump system. Additionally, the pump can be pre-biased for a more linear response, utilizing either mechanical or magnetic biasing methods. A controller is integrated to detect feedback signals from pressure and pump displacement transducers, enabling active control of the pump system. This invention is particularly beneficial for high-performance liquid chromatography.
