Title: Innovations of John S Cetnar
Introduction
John S Cetnar is an accomplished inventor based in West Manchester, OH (US). He holds a total of 3 patents that showcase his contributions to technology and innovation. His work primarily focuses on advanced detection systems and practical measuring devices.
Latest Patents
One of his notable patents is for terahertz (THz) distributed detectors and arrays. This invention discusses detectors that utilize structured surface plasmonic effects for more efficient coupling to free space. An example of this distributed detector includes a junction that comprises a Schottky or tunneling interface between a semiconductor and a detector metal. Additionally, it features an ohmic junction with an interface between the semiconductor and an ohmic metal, separated by a gap. When exposed to THz radiation polarized perpendicular to the gap, structured surface plasmons concentrate an electric field in the gap, enhancing detection capabilities.
Another significant invention is a hand-held labeling apparatus with an integral measuring device and printer. This innovative apparatus allows for automatic printing of measurement information obtained from the measuring device. It includes a measuring wheel with detectable marks, which is rotatably mounted on the housing. A sensor detects these marks and the presence of labels dispensed from the apparatus, enabling an on-demand printing mode. The controller responds to the sensor to manage printing and counting operations, making it a versatile tool for measuring dimensions of various objects.
