A sensor probe with reduced coupling between the various antenna elements and suppression of radio frequency interference. In one embodiment the sensor probe comprises a first antenna and a second antenna. A first and a second decoupling loop is electrically connected to one of the first and second antennas with current flow in opposite directions in the first and second decoupling loops. A third decoupling loop is electrically connected to another one of the first and second antennas and physically disposed between the first and second decoupling loops. Coupling between the first and second antennas is responsive to a location of the third decoupling loop relative to the first and second decoupling loops.

The invention relates to an operating unit (10) for at least one electromotive adjusting drive (7, 8) of a piece of furniture (1), having:—at least one operating element (12, 13),—a transmission unit (16) for wirelessly transmitting signals on the basis of actuation of the at least one operating element (12), and—a rechargeable energy store (17) for storing electrical energy for supplying power to the operating unit (10). The invention is distinguished by the fact that it has a device (20) for inductively receiving energy for charging the energy store (17). The invention also relates to a control system for controlling at least one adjusting drive of a piece of furniture, and to a piece of furniture having such a control system.

A resonant antenna for long-range wireless power transfer and communications. The antenna may be powered by a source at a frequency that is resonant for the antenna or harmonic(s) of the resonant frequency. The loop or antenna may be a wire laid out in a physically large network or constitute wiring of a building or other place. The antenna may be placed in a high index material, which results in the antenna to be a physically smaller size for the same electrical size. The antenna may be driven with an electrical power signal. Power may be picked up by another or secondary antenna from the source antenna at the resonant frequency or harmonic(s). Communications may also occur between the antennas. Because of a near-field effect, emanation of electromagnetic fields is primarily limited extensively to just between the antennas. A little stray electromagnetic field exists that others cannot easily intercept.

Described herein are techniques related to near field communication and wireless power transfers. A portable device may include a modular antenna that offers consistent characteristics independent of integration environment. The modular antenna may include a continuous loop of coil antenna and a ferrite material that are encapsulated by a shield. The shield may form a “U” shape configuration to encapsulate the top layer coil antenna and the middle layer ferrite material in all three sides, which are defined by a bottom portion, an outer wall, and an inner wall. Furthermore, the shield may include an outer rim and an inner rim to maintain the same coil antenna characteristics in the modular antenna.
