Abstract: A ventricular assist device (VAD) system includes one or more external subsystems including an amplifier energizing a drive loop with alternating current, and a Tx resonator inductively coupled to the drive loop. An implanted subsystem includes a VAD, an Rx resonator that forms a magnetically coupled resonator with the Tx resonator, and a load loop for providing power to the VAD that is inductively coupled to the Rx resonator. A sensor monitors the drive loop and a controller uses the sensor data to adjust a system parameter to optimize energy transfer performance. Distributing a plurality of the external subsystems throughout a defined space provides a patient with freedom of movement within the defined space.

Abstract: A system and method for linking data objects and physical objects of various kinds to an identified user is described. The system provides to the identified user information relating to the delivery status of mail pieces directed to or sent by the user, and the user then tracks and traces the mail pieces. The system further provides to the identified user information relating to continued sessions through which the user provides to a postal service system information relating to mailing labels and postage.

Abstract: A radio frequency identification (RFID) tag may have a non-responsive mode, triggered by a command from an RFID reader, that temporarily prevents the RFID tag from responding to a query from any RFID reader for a period of time. In some embodiments this non-responsive mode may automatically end after a certain period of time without further action by the RFID reader. In other embodiments this non-responsive mode may end when directed to by another command addressed specifically to the RFID tag.

Abstract: In accordance with various aspects of the disclosure, a method and apparatus is disclosed that includes feature of a transmitter and receiver having a substantially two-dimensional resonator structure including a flat coil; and an impedance-matching structure operably connected to the resonator structure, the transmitter configured to transmit power wirelessly.

Abstract: In accordance with various aspects of the disclosure, a method and apparatus is disclosed that includes features of transmitting power from a transmitter of a wireless power system at a multiplicity of frequencies between a first transmission frequency and a second transmission frequency at a first power level and transmitting power from the transmitter at a second power level and at one or more frequencies between the first transmission frequency and the second transmission frequency if the one or more receiving devices are determined to be coupled to the transmitter.

Abstract: One or more accelerometers may be coupled to a radio frequency identification (RFID) tag, so that the response of the RFID tag indicates the acceleration being sensed by the accelerometer(s). In some embodiments the accelerometers may be powered from the RF energy harvested by the RFID tag from a received RF signal. The sensed acceleration indicated in the response may be used to determine a motion and/or an orientation of an object coupled to the accelerometers.

Abstract: Various embodiments of the invention may use a radio frequency identification (RFID) tag with a writable non-volatile storage element to receive and store configuration parameters for a device connected to the RFID tag, even if the device itself is powered off. Upon power-up and startup of the device, the device may read the configuration parameters from the RFID tag and install them for its subsequent operation. Some embodiments may work in the opposite direction, by allowing the powered device to write its configuration data into the RFID tag's storage element, whose contents may subsequently be transmitted by the RFID tag to an RFID reader, even if the device is unpowered at the time of transmission.
