Patent ID: 8713512

Claim:
A system for programming domestic appliances during a manufacturing process, characterized by comprising: a remote programming unit that is physically separate and remote from the domestic appliance being programmed; and a processing unit integrated into the domestic appliance containing a reprogrammable processor; the remote programming unit being provided with a data transmission device and the processing unit containing the reprogrammable processor being provided with a data receiving device; the remote programming unit being loaded with at least one program code to be wirelessly transmitted by the data transmission device of the remote programming unit to the data receiving device of the processing unit containing the reprogrammable processor of the domestic appliance, the remote programming unit being configured to transmit the program code at the assembling line as a plurality of domestic appliances is passed in front of it; wherein the data is transmitted between the data transmission and data receiving devices by a magnetic field generating an induced voltage in the data receiving device; wherein the data receiving device comprises a passive circuit sensitive to magnetic fields and an active circuit for the treatment of signals, wherein the passive circuit sensitive to magnetic fields comprises a resonating inductor-capacitor topology, and the active circuit comprises an amplification stage in a common-emitter configuration, a rectification and filtering stage and an equalization stage of voltage levels, the active circuit for the treatment of signals converting electric signals provided by the passive circuit into electric signals compatible with the reprogrammable processor of the processing unit, and wherein the passive circuit sensitive to magnetic fields is tuned to a frequency range of 1 kHz to 530 kHz.
