A second antenna driver (24) is provided for driving a second antenna (21) for emitting a signal (104) in the event of identification of an ID transmitter (3) for the immobilizer of the vehicle. In addition, the electric circuit has a receiver device (14) for receiving a signal captured by an antenna (21) for the identification of an ID transmitter (3) for the immobilizer. The first antenna driver (12) and the receiver device (14) are commonly integrated into a semiconductor chip (1)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electric circuit for an access control and for an immobilizer of a vehicle and method for calibrating an antenna driver","description":"An electric circuit for controlling the access and immobilizing a vehicle has a first antenna driver (12) for driving a first antenna (19) for emitting a signal (100) in the event of identification of","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8461974","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.
