The processor selects the unrestricted state when a code input by the code inputting operation in the first restricted state is a preset code. Furthermore, whether or not the number of executions of the code inputting operation in the first restricted state is above a threshold value is repetitively determined, and if the determination result is negative, the first restricted state is selected while if the determination result is affirmative, the second restricted state is selected. Then, a possibility of a key operator being a qualified person is repetitively determined, and as the possibility is high, the threshold value is made large."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mobile terminal","description":"A mobile terminal includes a processor shifting a state between a first restricted state for restricting a key operation except for at least a code inputting operation, a second restricted state for r","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8543090","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.
