The drive unit includes a phase shift unit that shifts the phase to provide the drive signal as positive feedback to the oscillator. The phase shift unit includes a disturbance generating unit that outputs the periodic signal, a fluctuation unit that causes the amount of phase shift to fluctuate based on the periodic signal, a drive amplitude detection unit that detects the amplitude of the drive signal and outputs a drive amplitude signal, a product detection unit that outputs a detection signal after performing product detection on the drive amplitude signal based on the periodic signal, and an adjustment unit that adjusts the phase-shift amount based on the detection signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Oscillation device, scanning-type scanner device, information terminal, phase-shift amount adjustment device, and phase-shift amount adjustment method","description":"An oscillation device includes an oscillator, an oscillation detection unit that detects oscillation of the oscillator and outputs an oscillation detection signal, and a drive unit that generates a dr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9651777","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.
