Abstract: Various embodiments of a docking station configured for semi-autonomous or fully autonomous management of drones. In various embodiments, the station can identify the exact location and angle of a drone on a landing pad, and modify the location and angle in order for a robot to retrieve a used battery from the drone and also insert a fully charged replacement battery. The station may also determine the charge status of a drone's battery, the exact type of battery used by a particular drone, and select for replacement into the drone the specific battery needed. There are various embodiments of a system with such a docking station, command & control software, a database, and a network control center. Various embodiments are of methods to identify the need to replace a battery, identify the type of battery required, and effect replacement in an automated manner.

Abstract: A retrofitted credit card including a certified smart card chip, a display and retrofitted emulation circuitry operative to enable the certified smart card chip to communicate information to the display notwithstanding that the certified smart card chip is configured for communication only with an external read/write device.

Abstract: A system for authentication is provided which comprises an NFC card containing authentication data and a mobile communication device which can communicate with the card and a remote authentication server. The card, when activated, transmits authentication data stored on the card to the remote authentication server via the mobile communication device. The authentication server then transmits an authentication result to the mobile communication device. The authentication result can be used to complete a transaction such as a financial transaction. Either the card or the mobile communication device can contain the transaction data such as the user's account information needed to complete the transaction. The system can be used for secure remote access and re mote payment. A method of using the card is also provided.

Abstract: Powered cards comprising a substrate, a touch-sensitive display, display driver circuitry, a power source and a controller are described. The controller activates the display driver circuitry when a user of the card touches the display. The touch-sensitive display can be a liquid crystal display LCD which does not comprise a touch sensitive sensor separate from the display. Touch can be detected by measuring the capacitance between a conductor or segment and the common conductor of the display, wherein capacitance between a conductor segment and the common conductor is higher when the display is touched in an area near the segment. Capacitance between a conductor segment and the common conductor can be determined by measuring the time required for a segment of the display to transition to an on state during switching while the display is being driven by the display driver circuitry.
