When a first unit frequency signal and a second unit frequency signal chronologically adjacent to it are switched in a discontinuously switching state that is different from a continuously switching state where the first and second unit frequency signals are switched such that a target frequency for a transmission frequency changes continuously at a substantially constant rate, the drive signal generating unit shifts the frequency in at least a switching portion immediately after start of the second unit frequency signal, in a same direction as a direction of frequency change from the first unit frequency signal to the second unit frequency signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vehicle collision determination apparatus","description":"In a drive device for driving an ultrasonic transmitter, a drive signal generating unit generates a drive signal for driving the ultrasonic transmitter, based on a base signal having a plurality of un","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-12000969","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.
