Abstract: Embodiments are directed to methods and techniques for providing power via piezoelectric components on contactless cards.

Abstract: Disclosed is a contactless card, and a system in which the contactless card may be used. The contactless card may include a chip component, a communication interface, processing circuitry, and electromagnetic field sensing circuitry. The electromagnetic field sensing circuitry of the contactless card may be operable to provide orientation signals to the processing circuitry when the contactless card is in proximity to an oscillating electromagnetic field output by a card reader device. The processing circuitry of the contactless card may be operable to receive the orientation signals. An orientation of the contactless card with respect to the mobile device may be determined. An orientation indication signal may be generated based on the determined orientation, and a haptic indication, an audio indication, a visual indication or a combination directing movement of the contactless card in a particular direction may be output.

Abstract: A transaction card is provided. The transaction card can include a luminous layer having a sensitive information component. The sensitive information component includes personal account data and can be selectively illuminated by a light source by refracting light emitted by the light source. A switch and power source are provided to selectively energize the light source.

Abstract: Disclosed embodiments may include a system for sharing data. The system may direct a first user device to establish a respective wireless connection with second user devices. The system may cause the first user device to display, via a GUI, icons respectively corresponding to the second user devices. The system may track respective locations of the second user devices relative to the first user device, and may modify the GUI by repositioning the icons in the GUI based on the respective locations of each second user device relative to the first user device. The system may receive a request, from the first user device, to transfer data to a second user device of the second user devices based on a current position of an icon associated with the second user device in the modified GUI. The system may then transfer the data to the second user device.

Abstract: In some embodiments, a near-field communication card may be provided with an NFC-field-strength visualization display and a transparent window through which the NFC-field-strength visualization display is visible. In some embodiments, a token (e.g., the NFC card) may be constructed to include an electromagnetic field visualization display, a radiofrequency communication antenna, and a first transparent region having a transparent surface through which the electromagnetic field visualization display is visible. In some embodiments, a first layer of a token may be provided, where the first layer includes an electromagnetic field visualization display and a radiofrequency communication antenna. A second layer of the token may be provided, where the second layer includes a first transparent region. The first and second layers may be bonded such that the electromagnetic field visualization display of the first layer is visible through the first transparent region of the second layer.

Abstract: A laryngoscope (10) to assist tracheal intubation on a patient, comprising a body having a handle (14), and a laryngoscope blade (12) extending from the handle (14); a lighting system (21) including a light source integrated in the laryngoscope body and arranged in use to be activated to adopt an operational mode to provide illumination to the patient's throat; control means operative to allow only a single occurrence of the lighting system in the operational mode; and wherein once activated in the operational mode, the lighting system provides illumination for only a limited time.
