The present invention relates to a communication system comprising a removable device comprising a display screen, and a docking device apt to receive the removable device.

Each of the removable device and the docking device comprises an extreme high frequency communication chip, the communication chips being positioned opposite each other when the removable device is received in the docking device and are apt to exchange digital data between each other.

The display screen is apt to display images from the digital data sent by the communication chip of the docking device to the communication chip of the removable device.

A method for wirelessly coupling respective transducers of an automated motion platform and a sub-surface sensor node through a skin of a limited-access structure for the purpose of wireless power and data transfer. Coordinates of an as-designed position of the transducer of the sensor node in a local coordinate system of the limited-access structure are retrieved from a non-transitory tangible computer-readable storage medium. Then coordinates of a target position on an external surface of the skin of the limited-access structure are estimated. The target position is calculated to be aligned with the as-designed position of the transducer of the sensor node. The motion platform is moved under computer control so that the transducer onboard the motion platform moves toward the target position. Movement ceases when the transducer onboard the motion platform is at the target position. Then wave energy is transferred between the aligned transducers.

A near field communication system can include a near field generator configured to generate a near field detectable information signal. The near field generator and supporting circuitry also produces incidental electromagnetic radiation. A masking signal transmitter is used with the near field generator and radiates a masking electromagnetic signal. The masking electromagnetic signal may substantially mask the incidental electromagnetic radiation.

Embodiments may relate to a multi-chip microelectronic package that includes a first die and a second die coupled to a package substrate. The first and second dies may have respective radiative elements that are communicatively coupled with one another such that they may communicate via an electromagnetic signal with a frequency at or above approximately 20 gigahertz (GHz). Other embodiments may be described or claimed.

A near-field communication (NFC) antenna structure for radiation enhancement of a computing device that includes a ferrite sheet, separated into two sections. The NFC antenna structure may be used to improve (i) the magnetic field strength generated by an NFC antenna and (ii) inductive coupling to a receiving antenna of another computing device. A first ferrite section may be placed on a first side of the NFC antenna to at least partially overlap the NFC antenna, and a second ferrite section may be placed on a second side (opposite the first side) to at least partially overlap the NFC antenna. The first ferrite section may be positioned towards a top end that is often positioned closest to a receiving device, as held by a user when performing a contactless communication of the computing device, to increase the magnetic field strength and improve the inductive coupling at the top end.
