She filed a patent related to electronic circuit assemblies.
On January 19, 1966, Evelyn Berezin filed U.S. patent application US 3,461,552, titled "Electrical assemblage." This patent addressed the physical assembly and organization of electronic circuits, an important practical concern as computing systems grew more complex.
As systems architects like Berezin designed increasingly sophisticated computing devices, questions of how to physically assemble and organize electronic components became critical to reliability, manufacturability, and maintenance. This patent reflects her holistic engineering approach, addressing not just the logical design of systems but their practical, physical implementation.
This filing came during the period when Berezin was working on the design of the United Airlines reservation system, one of the first computerized airline booking systems, which required robust, reliable hardware assemblies capable of continuous operation. Her attention to the physical engineering details of electronic assemblies helped ensure that the ambitious real-time systems she was designing could function reliably at scale, a crucial but often overlooked aspect of pioneering computer engineering in the 1960s.
