The wearable devices are configured to detect, using one or more magnetometers, magnetic fields produced by (e.g., by permanent magnets or electromagnets) and/or modified by (e.g., by a shim or other element of magnetic material configured to have a specified high permeability) the external charger. The wearable device can change an operational state, display some information, receive power from the external charger to charge a battery of the wearable device, or perform some other function in response to determining some information about the external charger based on the detected magnetic field."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detection of accessory presence and orientation","description":"Wearable devices configured to detect a magnetic field related to the presence, proximity, relative location, relative orientation, configuration, identity, or other information about an eternal charg","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9685802","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.
