Abstract: A device may operate using power generated by an energy harvesting system that generates power from, wireless signals. The energy harvesting system may collect wireless signals and convert the signals to energy. In one form factor, a device utilizing an energy harvesting system may operate without a battery and without a connection to a wired power source. In some cases, super capacitors may be used to store small harvested amounts of power for use by the device.

Abstract: An electronic card with a programmable magnetic band which operates to emulate a magnetic stripe on a payment card. The card connects to a smartphone for reducing the amount of cards in a wallet using a NFC protocol. The electronic card with programmable magnetic band includes a magnetic stripe emulator, NFC communication unit, energy harvesting battery management, and high level security. Buttons are used to enter a personal code for using a default card. The card can be used on all payment terminals, and devices that can read magnetic stripes.

Abstract: A system and method for transferring data from one device to a second device using a pulse generator which may be included on one device as a component or as a separate accessory. The component or accessory sends electromagnetic waves to a circuit on the second device that is sensitive to electromagnetic signals such as a magnometer or magnetic sensor. An example of a devices that is doing the communicating could be between two phones, or a phone and an electronic card as disclosed herein, or a tablet and a phone.
