Latest Patents
One of Johnson's latest patents is a device for measuring the electronic characteristics of solid materials. This innovative device is designed to measure the electronic characteristics of solid electrolytes or solid-state electrochemical cells under varying conditions. It consists of two small flat plates that provide uniform physical and electrical contact with the material being measured. The device includes a spring for applying pressure to the plates and the material, along with electrical connections. This design ensures that the plates remain rigid and parallel, allowing for easy temperature measurement and handling.
Another significant patent by Johnson is a temperature-sensitive liquid level controlling apparatus. This apparatus employs a pair of carbon resistors, which change resistance in response to immersion in low-temperature liquids. It determines the upper and lower levels of the liquid in a container by comparing the resistances of the carbon resistors with those of reference resistors. This comparison provides a signal for controlling the flow of liquid into the container. The liquid cooling system that incorporates this apparatus effectively displaces liquid from a second container into the first by supplying a gaseous phase of the liquid into the second container.
