Title: The Innovations of Karl J Erb
Introduction
Karl J Erb is a notable inventor based in Gossau, Switzerland. He has made significant contributions to the field of optical measurement and electronic scales. With a total of two patents to his name, Erb's work showcases his expertise and innovative spirit.
Latest Patents
Erb's latest patents include a method and apparatus for optical measuring of a position. This method is based on tracking an interference pattern generated when line grids of different line densities are superimposed. The line grid of an optical scale is projected onto a line grid formed by a plurality of adjacently arranged diodes. Digital switching elements are allocated to the photodiodes and integrated on a common substrate, allowing for pair-wise comparison of the intensities of adjacent diodes. This method enables absolute position measurement through additional coding of the line grid of the scale, applicable in both linear and curvilinear measuring of positions.
Another patent focuses on an electrical balance with an acoustic feedback signal for manual dosing. This electronic scale controls material feed by generating a control signal as the material approaches a desired weight. An acoustic tone signal varies according to the control signal, reaching a limiting value when the actual weight matches the desired weight. This feature alerts the operator that the desired weight has been achieved.
