Password input data is received via the input device, when the mobile communication device is in the locked state, the password input data for unlocking the mobile communication device, the password input data comprising at least a sequence of characters for initiating an emergency call. In response to receiving the sequence of characters for initiating the emergency call, the display device is controlled to provide a representation of instructions to initiate the emergency call upon receipt of emergency call initiate data from the input device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for disambiguating an emergency call attempt during password entry for unlocking a mobile device","description":"A method and apparatus for unlocking a mobile communication device are provided, the mobile communication device comprising an input device, and a display device, the mobile communication device enabl","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8538403","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.
