Abstract: The disclosed apparatus may include a transparent NFC antenna that includes a transparent portion and a non-transparent portion. The transparent NFC antenna improves the radiation efficiency of standard NFC antennas by including a transparent conducting film such as metal mesh in the transparent portion, and metalized film in the non-transparent portion. The metalized film can extend along a narrow width of the perimeter of the transparent portion. In one implementation, the transparent NFC antenna can be incorporated into a touch-enabled display panel of a wrist-wearable device without interfering with the usability or viewability of the touch-enabled display panel. Various other implementations are also disclosed.

Abstract: The disclosed apparatus may include an antenna radiating structure that includes an active transparent mesh portion as well as a non-transparent antenna radiator portion. By combining transparent metal mesh and non-transparent metallic film into the antenna radiating structure, the disclosed apparatus results in improved radiation efficiency. Moreover, when overlaid on a transparent lens (such as with a pair of augmented reality glasses), the antenna radiating structure leaves the optical transparency of the lens largely unaffected due to the placement of the non-transparent metallic film. Various other implementations are also disclosed.

Abstract: The disclosed computer-implemented method may include accessing various antenna elements and identifying parameters for an antenna that is to be formed using the accessed antenna elements. The method may also include assembling the antenna elements, using an artificial intelligence (AI) instance, into an assembled antenna that at least partially complies with the identified parameters. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: The disclosed system may include a detachable capsule that includes a capsule-side capacitive plate. The system may also include a receiving antenna electrically connected to an antenna-side capacitive plate, and a capacitive sensor electrically connected to the capsule-side capacitive plate. The two plates may be coupled to each other and may transmit RF signals between them. The capacitive sensor may be configured to detect an amount of capacitance between the two capacitive plates. The system may also include an antenna matching tuner electrically connected to the capacitive sensor and to an antenna feed. Then, upon receiving capacitance measurements from the capacitive sensor, the antenna matching tuner may alter various parameters of the antenna feed including impedance matching parameters. Various other apparatuses and mobile wearable devices are also disclosed.

Abstract: The disclosed computer-implemented method may include accessing various portions of contextual information based on at least one touch input from a touch-based sensor on a mobile electronic device. The method may next include determining, based on the contextual information, which of different operational antenna parameters associated with at least one antenna of the mobile electronic device are to be changed. The method may then include changing the specified operational parameters associated with the antenna on the mobile electronic device according to the determination. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: The disclosed devices and systems may include transparent antennas and touch displays that may be included in wearable devices. An example wearable device may include a display module including a display stack, the display stack including a display cover layer, an antenna layer, and a display layer, wherein the antenna layer (1) is positioned between the display cover layer and the display layer, and (2) includes at least one antenna element. Various other systems and devices are disclosed.

Abstract: A method of encouraging environmental-friendliness among users of a network-based publication system is disclosed. It is detected that a user of a network-based publication system has engaged in a transaction. A transaction green score is calculated for the transaction. The transaction green score reflects an impact on the environment of the engagement by the user in the transaction. A user green score for the user is calculated. The calculating of the user green score includes combining the transaction green score with previous transaction green scores calculated for previous engagements by the user in previous transaction. The user green score is communicated for presentation in a user interface.
