Claims
- 1. A method for reducing power loss in devices for contactless data and energy transfer, including a stationary part having at least one coil for data and energy transfer, and a moveable part having at least one coil for data and energy transfer and having at least one memory unit, which comprises:
- transferring a test data word from the stationary part to the moveable part at a maximum energy, in an initializing mode,
- storing the transferred test data word in the memory unit of the moveable part,
- subsequently reading a test data word out of the memory unit of the moveable part with the stationary part and comparing the transferred test data word and the read-out test data word in the stationary part,
- reducing an energy supply if the transferred test data word and the read-out test data word match, and
- raising the energy supply by a defined amount and ending the initializing mode, if the transferred test data word and the read-out test data word do not match.
- 2. A method for reducing power loss in devices for contactless data and energy transfer, including a stationary part having at least one coil for data and energy transfer, and a moveable part having at least one coil for data and energy transfer and having at least one memory unit, which comprises:
- a) transferring a test data word from the stationary part to the moveable part at a maximum energy, in an initializing mode;
- b) storing the transferred test data word in the memory unit of the moveable part;
- c) subsequently reading a test data word out of the memory unit of the moveable part with the stationary part;
- d) comparing the transferred test data word and the read-out test data word in the stationary part; and
- e) if the transferred test data word and the read-out test data word match, reducing an energy supply, transferring the test data word from the stationary part to the moveable part at the reduced energy, and repeating steps b)-d);
- f) if the transferred test data word and the read-out test data word do not match, raising the energy supply by a defined amount and ending the initializing mode.
