    摘要: An adjustable inductor including a toroidal core defining a plurality of gaps, a compressible gap material positioned in the gaps, at least one winding wound on the core, a force-applying structure, and a film substantially covering the adjustable inductor. The force-applying structure is operable to apply a force to the core to adjust the gaps and thereby an inductance of the adjustable inductor. The film is configured to prevent movement of force-applying structure when above a predetermined temperature threshold, and allow movement of the force-applying structure when below the predetermined threshold.

    摘要: A device for inductive energy transfer between a stationary three-phase primary system and a mobile three-phase secondary system shows a stationary iron core part and two mobile iron core parts (3, 5) which are connected electrically in series are each designed as an equilateral triangle or as a star which spans an equilateral triangle and has limbs (3a, 3b, 3c; 5a, 5b, 5c) of equal length which run at the same angle in relation to one another, and supporting posts (3a′, 3b′, 3c′; 5a′, 5b′, 5c′) which start from the ends of said limbs, and also primary and secondary windings (4, 6) which are arranged at the same distance from one another. The device of simple design has a high degree of efficiency in respect of energy transfer. In the case of energy transfer only in the inoperative state, a stationary iron core part and a mobile iron core part can also be positioned directly one on the other without magnetic rails.

    摘要: A docking station that securely holds a portable electronic device in a desired location with respect to a primary power coil for inductive charging of a battery of the portable electronic device is provided. In one embodiment the docking station includes a pair of opposed end stops spaced apart longitudinally along a base and a primary coil of an inductive charging system positioned below the base. The end stops are longitudinally adjustable to properly align a secondary coil of the portable electronic device with a primary coil. A flexible retention wall may be deflected to provide a biasing force on the portable electronic device. Walls of the end stops are generally curved toward each other and provide downward pressure to prevent vertical and horizontal movement. In another embodiment, a retainer clip is movably coupled with and selectively slides along the base to securely hold the portable electronic device.

    摘要: A tunable inductor includes a first wire coil having a first terminal lead, and a second wire coil having a second terminal lead that is arranged and oriented in the same direction as the first terminal lead. The tunable inductor further includes a connecting bridge connecting the first wire coil with the second wire coil opposite the first and second terminal leads, such that the first wire coil and second wire coil are arranged in series and spaced side-by-side separated by a space. The tunable inductor further includes a mechanical tuning mechanism coupled with the connecting bridge, to provide a force down onto or a force pulling up the connecting bridge, and to respectively decrease the space between the first wire coil and the second wire coil to increase inductance, or increase the space between the first wire coil and the second wire coil to decrease inductance.

    摘要: Provided is a material for tactile sensor, which is easy to be formed, and in which the shape, size and orientation of coils dispersed in the medium are sufficiently controlled. The tactile-sensitive material includes a medium and a plurality of micro coils dispersed in the medium and constituting a LCR resonance circuit, and wherein each of the plurality of micro coils includes at least one spiral coil portion, and coil axes of the plurality of micro coils are aligned along at least one direction or directed in at least one plane. When a tactile stress is applied to the tactile-sensitive material, the C component is varied significantly, which contributes to the improvement in sensitivity of the tactile sensor. Further, by providing a core at the coil center, the sensitivity is more improved.
