摘要： In a general aspect, a method can include producing, by an inductive antenna circuit, a first periodic signal that is based on an alternating external magnetic field; producing, by an oscillator circuit, a second periodic signal that is based on the first periodic signal; and transmitting, in correspondence with a data-carrying modulation signal, a sequence of data bits. The transmitting can include sequentially and repetitively: applying, with the oscillator circuit operating in a free oscillation mode, the second periodic signal to the inductive antenna circuit; and inhibiting, with the oscillator circuit operating in a synchronous oscillation mode, application of the second periodic signal to the inductive antenna circuit. The synchronous oscillation mode of the oscillator circuit can cause the second periodic signal to be synchronized to the first periodic signal.

摘要： In a general aspect, an electronic device can include a device configured to transmit data by intracorporeal current. The device configured to transmit data by intracorporeal current can include a first electrode configured to be capacitively coupled with a body of a user or capacitively coupled in an intracorporeal current conduction path of the electronic device. The electronic device can further include a circuit configured to electrically bias the first electrode. The circuit can include an electric coil arranged near the first electrode. The electric coil can be configured to, in response to an alternating-current (AC) signal, generate an alternating magnetic field having field lines incident on the first electrode. The field lines incident on the first electrode can induce a current in the first electrode, where the current induces an electric field that generates an intracorporeal current.

摘要： A method for sending data by inductive coupling includes: extracting an antenna signal from an antenna circuit, extracting from the antenna signal a first periodic signal, producing a second periodic signal by way of a synchronous oscillator, placing the oscillator in a free oscillation mode and applying to the antenna circuit the second periodic signal, modifying the impedance of the antenna circuit, restoring the amplitude of the antenna signal, then resynchronizing the oscillator on the first periodic signal.

摘要： In a general aspect, a method for transmitting data between an NFC card and an external NFC device via a selected interface (e.g., contact or contactless), and further via a contactless interface of the NFC module when the contact interface of the NFC card is selected can include using an NFC card that includes an antenna circuit having an antenna coil with a magnetic axis and an electrically conductive screen extending near the antenna coil. The magnetic axis of the antenna coil can be substantially parallel to a plane defined by the NFC card and not cross the conductive screen. The contactless interface of the NFC card, when selected by the NFC card, can emit data by emitting bursts of magnetic field from the antenna coil, so as to compensate for effects of the conductive screen on a maximum distance for transmitting data by load modulation.
