18 ABSTRACT: A process for the contactless transfer of energy and data in a combined mechanically/electronically coded lock having current-powered main electronics and non- powered subelectronics. The data and energy transfer is performed via coupling elements connected to the main and subelectronics, respectively. The energy and data exchange is controlled by a microcontroller in the main unit such that energy or data are transferred alternatingly via the coupling elements. By a variation of the energy pulse length, the transferred energy is automatically adapted to the energy consumption of the subelectronics, including transmission losses. The starting moments of the data sequences in the subelectronics are synchronized with the sequences in the main electronics.
