Abstract
Official abstract text for this publication.
A system for testing electromagnetic compatibility of electrical devices includes a plurality of mobile-ground-planes and a fixed-ground-plane. Each of the plurality of mobile-ground-planes is individually customizable to provide a test-fixture for testing a selected instance of an electrical device. The fixed-ground-plane is configured to receive an instance of the plurality of mobile-ground-planes to overlay the fixed-ground plane and form a direct electrical contact between a bottom-side of the instance of the plurality of mobile-ground-planes and a top-side of the fixed-ground-plane. Optionally, the system includes an air-nozzle used to generate an air-gap between the instance of the plurality of mobile-ground-planes and the fixed-ground-plane while the instance of the plurality of mobile-ground-planes is being placed onto the fixed-ground-plane when gas passes through the air-nozzle.
First claim
Opening claim text (preview).
We claim: 1. A system for testing electromagnetic compatibility of electrical devices, said system comprising: a mobile-ground-plane, wherein the mobile-ground-plane is individually customizable to provide a test-fixture for testing a selected instance of an electrical device; and a fixed-ground-plane configured to receive an instance of the mobile-ground-plane to overlay the fixed-ground plane and form a direct electrical contact between a bottom-side of the instance of the mobile-ground-plane and a top-side of the fixed-ground-plane. 2. The system in accordance with claim 1 , wherein the system includes an air-nozzle used to generate an air-gap between the instance of the mobile-ground-plane and the fixed-ground-plane while the instance of the mobile-ground-plane is being placed onto the fixed-ground-plane when gas passes through the air-nozzle.
