摘要： A wireless resonant powering device 1 according to the invention comprises a first inductor winding 3, which is arranged to form a transformer 9 with the inductor winding 13 of the energizable load 11. The first inductor winding 3 is arranged to form a resonant circuit 5, which may comprise a suitable plurality of electric capacitances and coils. The components of the resonant circuit 5 are selected such that the magnetic energy received by the inductor winding 13 damps the energy flow in the resonant circuit so that the induced voltage in the inductor winding 13 is substantially constant and is independent of the magnetic coupling between the first inductor winding 3 and the inductor winding 13 at the operating frequency of the driving means 6. The resonant circuit is driven by the driving means 6, comprising a control unit 6c arranged to induce an alternating voltage between a first semiconductor switch 6a and a second semiconductor switch 6b. At the output of the transformer 9 an alternating voltage is generated, which is rectified to a DC-voltage by a diode rectifier, filtered by an output capacitance. The resonant circuit 5 is operable on its coupling independent point by the driving means 6. This figure schematically illustrates a situation, where a variable coupling between the first inductor winding 3 and the inductor winding 13 exists. The invention further relates to a wireless inductive powering device, an energizable load, a wireless system and a method for wireless power transfer.

摘要： The invention relates to an illumination device for embedding data symbols of a data signal into a luminance output of the illumination device. The device includes a LED comprising at least two segments which have a common electrode and are individually controllable. The LED is configured to generate the luminance output in response to a drive signal. The device further includes a controller configured for switching one of the segments on or off in response to the data signal to embed data symbols of the data signal into the light output of the device. One advantage of such an approach is that the proposed device is compatible with conventional LED drivers since no additional electronics for modulating the drive signal are necessary, which enables simple implementation and reduced costs.

摘要： A control unit (2) of a remote control receiver sets the forward or reverse direction operating mode of the photodiode (1) as a function of the useful signal level of its output signal, and to be precise, during standby, the photovoltaic operating mode (forward mode), since in this mode no external bias current is required. If the useful signal level of the photodiode (1) exceeds a predefined threshold, the reverse mode is set, and this brings with it a higher sensitivity. A series circuit (A) of a number of identical photodiodes DA1 DAn in the forward mode allows the realization of a controlled current source (6) having a transistor (T), since the permissible diode voltage (Ud) of the overall arrangement may have n times the value of the operating voltage of an individual photodiode. Thus at the same time the voltage across the individual diodes can be set to a very low value and a favorable operating range for the current source can be set. The possible sensitivity of the receiver module having diodes in this operating mode can thereby be considerably increased.
