The smartphone comprises a display device, an input device, and two communication devices. The application function unit comprises a connection verification device and a suitcase lifting prevention device. The tag comprises: two communication units which correspond with the two communication devices of the smartphone; a light emitting unit; a control unit; and a power supply unit. The control unit controls each of a connection establishment mode, a sleep mode, and a wake-up mode. In the wake-up mode, the light emitting unit is caused to emit light at a blink interval which corresponds to the strengths of two radio waves.The light emitting unit is provided with a light guiding plate. The light guiding plate comprises an acrylic plate and a film adhered to the acrylic plate, and functions as an identification marker for the possessor of the tag. It is desirable for a power switch of the tag to be locked."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Travel suitcase search system and tag","description":"To allow a smartphone and a tag to cooperate in searching for a suitcase, this suitcase search system comprises a smartphone, an application function unit which is implemented by an application progra","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11990021","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.
