The electronic switch sets a voltage state of an electrical connection to the host device that triggers the host device to begin providing power. The accessory may no longer receive power from the host device once the wireless signal stops. The host device may be the source of the wireless signal and may thereby control whether the accessory draws power by operation of the wireless signal. Alternatively, the accessory may include a controller that once powered on by the host device as a result of the rectification of the wireless signal, maintains the same or a different electronic switch in a closed state to maintain power delivery from the host device until the controller is triggered to allow the electronic switch to open."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods, devices, and systems where an accessory controls power delivery from a host device to the accessory through an accessory port","description":"An accessory controls power delivery from a host device to the accessory by receiving and rectifying a wireless signal into an electrical voltage that operates an electronic switch.
