Patent ID: 7236809

Claim:
A method for registering battery-operated mobile parts at a base station comprising a battery-charging unit, comprising: establishing a ready-to-register state between the mobile part to be registered and base station; executing a registration procedure via wireless communication, wherein prespecified registration data comprising base station, mobile part, system and product-specific identifications, are transmitted between the registering mobile part and the base station; storing the registration data; establishing the readiness to register by performing the steps of (a) introducing the mobile part to be registered into a battery-charging unit of the base station, wherein the mobile part becomes connected to the base station via charging contacts; (b) performing trickle-charging to a battery of the mobile part to be registered for a predetermined time; (c) checking in the mobile part to be registered whether registration data is stored in the mobile part, in which case the process of establishing the ready-to-register state continues if no registration data is stored, or is aborted if data is already stored; (d) transferring from the mobile part to be registered to the base station a signal via the charging contacts, wherein the signal notifies the base station of the ready-to-register state on the mobile part side; (e) detecting the signal at the base station and transmitting a conformation signal from the base station to the mobile part via the charging contact to confirm to the mobile part the receipt of the signal and notifies the base station side ready-to-register status; and (f) detecting the confirmation signal at the mobile part to be registered wherein the detection of the confirmation signal initiates a registration procedure.
