The system includes a control circuit configured to receive a temperature measurement for each of the plurality of zones, collect the temperature measurements in a temperature vector in a real coordinate system, and transform the temperature vector to a normal coordinate system that provides a plurality of uncoupled equations. The control circuit is configured to determine, based on the plurality of uncoupled equations and a desired temperature gradient, a desired power vector in the normal coordinate system, transform the desired power vector to the real coordinate system to generate a power vector, and control the plurality of heaters in accordance with the power vector."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Integrated circuit testing device with coupled control of thermal system","description":"A system includes a plurality of thermally-coupled zones and a plurality of thermal control devices, each controllable to thermally control one of the plurality of zones, and a plurality of temperatur","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-12000884","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
