Title: The Innovations of Lieuwe Boonstra
Introduction
Lieuwe Boonstra is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of semiconductor devices and optical information reading technologies. With a total of 4 patents to his name, Boonstra's work has had a considerable impact on modern technology.
Latest Patents
One of his latest patents is the "Charge pump substrate bias generator." This invention involves a semiconductor device that features an integrated circuit where a region of one conductivity type is charged by supplying charge carriers from a zone of the opposite conductivity type. This process occurs below a field electrode where a voltage is established. When the voltage is turned off, some charge carriers recombine in the region. The innovation includes an electronic switch that prevents the backflow of charge carriers to the supply conductor when the inversion layer disappears.
Another significant patent is for an "Apparatus for reading a record carrier with optical information." This apparatus is designed to read information stored in an optically readable structure. It splits the radiation supplied by the source into a read beam and an auxiliary beam, which helps determine the focusing of the read beam on the record carrier. The auxiliary beam is intercepted by two radiation-sensitive detectors, and a radiation-absorbing knife is used to block part of the auxiliary beam, allowing for accurate indications of focusing errors.
