Definitions

  • the capacitance of a reference capacitor 126 may be input to converter 144, such that the converter converts the capacitance of the reference capacitor into the output frequency.
  • the voltage across the antenna would need to be significantly higher.
  • the voltage across the antenna when loaded with the current-drawing circuitry would need to be approximately 20 V, and hence, the voltage across the antenna when unloaded might need to be approximately 40 V.
  • the voltage across the antenna when unloaded is approximately 20 V.
  • the antenna would need to be supplied with a large amount of energy.

Abstract

L'invention concerne un appareil (20) comprenant un circuit frontal (30) et un circuit de traitement numérique (28). Le circuit frontal comprend une antenne (32) et un commutateur de modulation (40). Le circuit de traitement numérique est configuré pour transmettre des données à une unité à distance (50) À l'aide d'un couplage inductif d'un champ magnétique à courant alternatif (CA) généré par l'unité à distance, par modulation d'une impédance de charge de l'antenne à l'aide du commutateur de modulation. Le circuit frontal est configuré pour fournir au circuit de traitement numérique un signal de tension, comprenant une fréquence du champ magnétique alternatif et comprenant une enveloppe non nulle à la fois pendant des intervalles dans lesquels le commutateur de modulation est fermé et pendant des intervalles dans lesquels le commutateur de modulation est ouvert, et le circuit de traitement numérique étant configuré pour dériver un signal d'horloge à partir du signal de tension.
