Abstract:
A retinal prosthesis including an electronic stimulation unit housed inside an eye and including: a plurality of electrodes that contact a portion of a retina of the eye; an electronic control circuit, which is electrically connected to the electrodes and supplies to the electrodes electrical stimulation signals designed to stimulate the portion of retina; and a local antenna connected to the electronic control circuit. The retinal prosthesis further includes an electromagnetic expansion housed inside the eye and formed by a first expansion antenna and a second expansion antenna electrically connected together, the first expansion antenna being magnetically or electromagnetically coupled to an external antenna, the second expansion antenna being magnetically or electromagnetically couple to the local antenna, the electromagnetic expansion moreover receiving an electromagnetic supply signal transmitted by the external antenna and generating a corresponding replica signal.
Abstract:
A security system includes an integrated circuit and a transceiver/transponder circuit. The integrated circuit includes an antenna for communicating with the transceiver/transponder circuit. An inhibiting element is associated with the integrated circuit for inhibiting communications with the transceiver/transponder circuit and for securing the data contained in the integrated circuit. The inhibiting element is an electromagnetic inhibiting element. The security system further includes a coupling element associated with the antenna of the integrated circuit for temporarily deactivating the electromagnetic inhibiting element to allow communications between the integrated circuit and the transceiver/transponder circuit.
Abstract:
An embodiment of an integrated electronic device having a body, made at least partially of semiconductor material and having a top surface, a bottom surface, and a side surface, and a first antenna, which is integrated in the body and enables magnetic or electromagnetic coupling of the integrated electronic device with a further antenna. The integrated electronic device moreover has a coupling region made of magnetic material, which provides, in use, a communication channel between the first antenna and the further antenna.
