    摘要： An autonomous battery-free microwave frequency communication device which includes a capacitance, at least one antenna, a microwave energy harvesting system, a microwave frequency transceiver, and a control system. The energy harvesting system is configured to harvest and store microwave energy received via the antenna onto the capacitance. The transceiver is empowered by energy stored on the capacitance, and is configured to autonomously generate a microwave frequency carrier and to autonomously transmit information using the microwave frequency carrier according to a predetermined communications protocol via the antenna. The control system is empowered by energy stored on the capacitance, and is configured to provide information for transmission. Energy may be harvested from various communication forms, such as wireless network protocols or cellular communications. The frequency band from which energy is harvested may differ from the frequency band used for communications. The energy storage enables autonomous communications with external devices according to common or standard wireless communication protocols.

    摘要： Initialization of a semiconductor device can be efficiently performed, which transmits and receives data through wireless communication. The semiconductor device includes an antenna, a power source circuit, a circuit which uses a DC voltage generated by the power source circuit as a power source voltage, and a resistor. The antenna includes a pair of terminals and receives a wireless signal (a modulated carrier wave). The power source circuit includes a first terminal and a second terminal and generates a DC voltage between the first terminal and the second terminal by using a received wireless signal (the modulated carrier wave). The resistor is connected between the first terminal and the second terminal. In this manner, the semiconductor device and the wireless communication system can transmit and receive data accurately.

    摘要： A system for controlling assignment and management of identities in ambient electromagnetic power harvesting (AEPH) chips. The system comprises a processor; a non-transitory memory; and an application stored in the non-transitory memory that, when executed by the processor, allocates a plurality of unique AEPH identities, wherein each unique identity comprises an identity of a product item and an instance identity; stores the plurality of unique AEPH identities in a first immutable record in a datastore, wherein the unique AEPH identities are associated with an initial state; provides the plurality of unique AEPH identities to an original equipment manufacturer of AEPH chips; provides an application programming interface (API); authorizes a request to update a state associated with a first unique AEPH identity in the datastore; and adds a second immutable record to the database that associates the first unique AEPH identity with an updated state of the first unique AEPH identity.
