Disclosed are devices and methods for performing wireless charging of an electronic device and establishing a wireless connection with the electronic device for receiving data from the electronic device. Different modes of wireless data reception from the electronic device can be used to ensure that a power supply of the electronic device is charged without interruption.

An electronic device and method of operating an electronic device are provided. The method includes receiving a wireless charging request from an external electronic device while wireless communication with the external electronic device is performed through a communication circuit of the electronic device, identifying a second frequency, based on a first frequency being used by the wireless communication circuit for the wireless communication, in response to the wireless charging request, and transmitting wireless power to the external electronic device, based on the identified second frequency through a wireless charging circuit of the electronic device while wireless communication with the external electronic device is performed.

The present invention relates to the field of medical appliances, more particularly to a communication system of an implantable device, comprising an external unit and an implantable unit, wherein the external unit and the implantable unit realize charging and bidirectional signal transmission of the external unit to the implantable unit by a wireless signal, two coupling coils are disposed outside the body, one for transmitting the forward signal, and one for receiving the reverse signal, and one coupling coil is disposed in the body for receiving and feeding back the signal, wherein the setting of the shape and position of the two coupling coils outside the body avoids the reverse signal fed back from inside of the body to be disturbed, thereby achieving effective transmission of the bidirectional signal, and overcoming the problem that the signal has weak signal strength and tends to be interfered when the traditional implantable device transmits the signal in a reverse direction.

An integrated circuit package includes a lead frame and an encapsulation that substantially encloses the lead frame. The lead frame further includes a first conductor comprising a first conductive loop and a second conductor galvanically isolated from the first conductor, proximate to and magnetically coupled to the first conductive loop to provide a communication link between the first and second conductor. The second conductor includes a first conductive portion, a second conductive portion, and a wire coupling together the first conductive portion and the second conductive portion.

Wireless power transfer systems, disclosed, include one or more circuits to facilitate high power transfer at high frequencies. Such wireless power transfer systems include a damping circuit, configured to dampen a wireless power signal such that communications fidelity is upheld at high power. The damping circuit includes at least a damping transistor that is configured to receive, from the transmitter controller, a damping signal for switching the transistor to control damping during transmission of amplitude shift keying (ASK) wireless data signals. Utilizing such systems enables wireless power transfer at high frequency, such as 13.56 MHz, at voltages over 1 Watt, while maintaining fidelity of in-band communications associated with the higher power wireless power signal.

The method includes one or more processors detecting a request from a computing device for a service. The method further includes one or more processors establishing a request from a computing device for a service. The method further includes one or more processors determining whether the computing device maintains connection to the NAN. In response to determining that the computing device does not maintain a connection to the NAN, the method further includes one or more processors cancelling the detected request for the service.

A method comprising: establishing a wireless connection between a first medical device and a second medical device, comprising: receiving, by the first medical device, via a short-range wireless technology protocol, connection information related to the second medical device; and establishing, by the first medical device, a wireless connection with the second medical device based on the connection information.

According to the present invention, the communication mode can be prevented from changing when re-authentication is performed. To achieve this, a power supply apparatus that wirelessly supplies power to an electronic device, comprises a communicating unit that contactlessly transmits power and transmits/receives information, a holding unit that holds, when authentication is first performed with an electronic device via the communicating unit, information indicating a communication mode when communication is established with the electronic device, and a controlling unit that controls the communicating unit so as to perform communication in a communication mode based on the information held in the holding unit, when a second authentication is performed with the electronic device via the communicating unit.

Disclosed is a system which extends NFC near field communication over a user's skin by converting electromagnetic signals into modulated alternating electric fields and vice versa. A modified patch is attached to an NFC device, which gets energized from its electromagnetic resonance which may contain data. The patch uses the energy to create an alternating electric field which couples into and spreads over a user's skin. The user may approach or touch objects which then get energized by the alternating electric field. The objects have a tag which modulates the electric field with data back over the user's skin to the patch, which then demodulates the data to modulate the NFC communication of the NFC device for further processing.
