The tip is sensitive to contact pressure. The sensor detects the contact pressure. Memory stores at least one pre-defined first threshold and a pre-defined second threshold on the contact pressure. The first threshold defines tip state as one of a pen-up and a pen-down. Pressures below the first threshold defines pen-up and pressures above the first threshold define pen-down. The second threshold is below the first threshold. The circuit transmits in a hover transmission mode based on detecting pressures below the second threshold, switches to an writing transmission mode based on detecting a pressure at or above the second threshold and terminates the writing transmission mode based on detecting the pen-up status for a first pre-defined period. The writing transmission mode frame rate is higher than a hover transmission mode frame rate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch down detection with a stylus","description":"A device includes a tip, a sensor, memory and a circuit.
