Title: The Innovative Contributions of Donald E. Lake
Introduction
Donald E. Lake is a notable inventor based in Kokomo, IN (US). He has made significant contributions to the field of technology, particularly in the development of devices that are sensitive to magnetic fields and pressure sensors. With a total of 2 patents to his name, Lake's work showcases his expertise and innovative spirit.
Latest Patents
One of Lake's latest patents is for a "Package for the Magnetic Field Sensitive Device." This invention involves a package designed for a magnetic field sensitive element, such as a magnetoresistor. The package consists of at least two planar layers made from a relatively stiff ferromagnetic material that is also electrically conductive. These layers are positioned closely together to form a narrow gap, with terminal tabs extending from each layer. A magnetic field sensitive element is placed on the surface of at least one of the layers, and a permanent magnet is mounted on the opposite surface. This design enhances the functionality and protection of the magnetic field sensitive element.
Another significant patent by Lake is the "Pressure Sensor Assembly." This invention features a silicon chip with a diaphragm that contains piezoresistive strain responsive resistors. The chip is housed in molded polyester material, which has a different temperature coefficient of expansion than the chip itself. The mounting arrangement includes a glass base that is secured to the housing with a soft adhesive, minimizing stress transmission. This innovative design ensures the silicon chip is protected from thermally induced stresses, enhancing the reliability of the pressure sensor.
