Title: The Innovative Contributions of Gunnar Wennerberg
Introduction
Gunnar Wennerberg is a notable inventor based in Cupertino, California. He has made significant contributions to the field of optical sensing technology, holding a total of seven patents. His work primarily focuses on developing advanced sensors for measuring physical properties of materials.
Latest Patents
Wennerberg's latest patents include a "Single Sided Reflectance Sensor for Measuring Select Physical Properties." This innovative sensor features an optical arrangement that allows for accurate measurements of select physical properties of a moving sheet. It consists of a protective enclosure positioned adjacent to the sheet surface, containing an electromagnetic radiation source that projects an incident beam onto the sheet. The sensor also includes a reflectance sensing mechanism to measure the intensity of the reflected beam, along with a planar convex lens designed to enhance measurement accuracy while minimizing sensitivity to sheet flutter.
Another significant patent is the "Optical System for Detecting Properties of Traveling Sheet Materials." This system employs a first group of optical fiber bundles to convey light to specific locations adjacent to one face of the sheet material. A second group of optical fiber bundles collects light transmitted through the sheet and conveys it to a light detector. This detector measures the intensity of light received, providing valuable data on the optically-sensitive properties of the sheet material at various cross-directional locations.
