Abstract: A batteryless wireless sensor system includes a data acquisition system, a radio frequency (RF) transceiver, and a batteryless wireless sensor device. The RF transceiver is in communication with the data acquisition system, transmits a RF signal, and receives sensor data and provide the sensor data to the data acquisition system. The batteryless wireless sensor device includes a RF transmitter, an analog to digital converter (ADC), and a sensor. The batteryless wireless sensor harvests energy from the RF signal and generates a DC signal based on the energy harvested from the RF signal, powers up and operates the ADC and the sensor based on the DC signal, and generates sensor data. The batteryless wireless sensor then transmits the sensor data via the RF transmitter to the RF transceiver. In certain examples, the ADC is implemented as a current mode ADC.

Abstract: A wearable article, system, and methods may include a structure configured to enclose a human body part. A first antenna, positioned with respect to the structure, is tuned to communicate, while the wearable article is being worn, according to a first wireless communication modality with a first external antenna. A second antenna, positioned with respect to the structure, is tuned to communicate according to a second wireless communication modality with a second external antenna different than the first external antenna, the second communication modality being different than the first communication modality. A transceiver, coupled to at least one of the first antenna and the second antenna, is configured to communicate via one of the first and second antennas based, at least in part, on the one of the first and second antennas coming into wireless communication contact with a corresponding one of the first and second external antennas.

Abstract: Systems and methods for operating a security tag. The methods comprise: receiving a first wireless signal transmitted from a transmit circuit using a receive circuit of the security tag; inducing a voltage in the receive circuit of the security tag while the first wireless signal is being received; performing operations by the controller to selectively close a switch when the voltage is being induced in the receive circuit; and causing a release of a mechanical component of the security tag by allowing energy to flow from the receive circuit to the mechanical component when the switch is closed.

Abstract: A system for sensing a proximity of a near field communication (NFC) device includes an NFC reader that communicates with a remote NFC device through load modulation. The NFC reader transmits a wireless carrier signal from an antenna, and the remote NFC device modulates the carrier signal by changing its internal impedance in order to transmit data to the NFC reader. The NFC reader has at least one antenna for receiving the modulated signal. The antenna is coupled to circuitry that analyzes the signal received from the remote NFC device The circuitry then identifies a resonant frequency for the remote NFC device based on the received signal and controls transmission characteristics of the NFC reader for communicating with the remote NFC device based on the identified resonant frequency.

Abstract: This disclosure describes systems and techniques for enabling a communication device to communicate wirelessly with a near-field-communication (NFC)-enabled payment terminal while avoiding interference between the NFC-enabled payment terminal and other NFC payment instruments. In some instances, the communication device may receive, via a non-NFC communication protocol, a payment token from an identification device and may send, over NFC, the payment token to the NFC-enabled payment terminal for satisfying the cost of a transaction.
