The method includes applying a time-dependent current variation to one end of the cable in accordance with a spreading sequence, detecting a time-dependent voltage variation at the one end of the cable, the time dependent voltage variation resulting from the applying of the time-dependent current variation, and determining a quantity indicative of an impedance of the cable assembly based on the time-dependent voltage variation and the spreading sequence. Further, an apparatus for monitoring a process of powering a portable device through a cable connected between a power supply and a portable device is presented."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for powering a portable device","description":"A method of monitoring a process of powering a portable device through a cable connected between a power supply and a portable device is presented.
