Latest Patents

One of her key inventions is a multi-scale indicator, which features a main scale and a sub-scale designed to prevent misreading between the two. The invention includes a sub-scale prism and a dedicated light source that illuminates only the sub-scale, ensuring that it is light insulated from the main scale prism and its light source. This design is achieved by securely embedding the sub-scale prism within a circular arc-shaped prism receiving groove on the main scale prism. Additionally, light opaque paint is applied between the main scale prism and the sub-scale prism to eliminate light leakage. The invention also incorporates an electrical control that activates the light for the sub-scale prism only when the pointer is positioned within a predetermined zone at the end of the main scale. This innovative approach enhances the functionality and reliability of measurement devices.
