Title: David A. Haak: Innovator in Aircraft Load Management and Power Supply Systems
Introduction
David A. Haak is a notable inventor based in Rockford, IL (US), recognized for his contributions to aircraft load management and power supply systems. With a total of 2 patents, Haak has made significant advancements in the field of aviation technology.
Latest Patents
Haak's latest patents include the "Aircraft Load Management Center" and "DC Power Supply for High Power Applications." The Aircraft Load Management Center features a design where each Line Replaceable Unit (LRU) is addressed by a separate line. Power control units on an LRU are connected via a bus, allowing for parallel connections of all LRUs. This innovative system ensures that control and status inputs, as well as status output lines, are efficiently managed. A programmable logic unit on each LRU decodes controller addresses and couples control and status request inputs to the controller. The load management center automatically connects a status signal to the interface output after each control function input.
The second patent, the DC Power Supply for High Power Applications, includes multiple DC to DC converters that convert a multi-phase AC potential into a DC output potential. This system effectively combines the DC output of each converter into a single output while cancelling any undesired AC components. A controller produces a time reference applied to each converter, ensuring an angular relationship between the phases of each converter.
