  • Patent number: 10481189
    Abstract: A wireless remote sensor (110) that is powered by an inductive transmitter (112) and is configured to produce an oscillating wave that varies based on one or more sensed parameters. The oscillating wave is communicated to the inductive transmitter (112) by reflected impedance, where it can be detected to determine the sensed value(s). In another aspect, the present invention provides a wireless remote sensor with a Wheatstone bridge arrangement having an internal resonant circuit to produce an electromagnetic field indicative of the sensed value. In a third aspect, the present invention provides a wireless remote sensor with optical feedback from a reference circuit and a sensor circuit. In a fourth aspect, the present invention provides a wireless remote temperature sensor having coils printed on a material with a high coefficient of thermal expansion so that the size and/or shape of the coils varies as the temperature increases or decreases.

  • Patent number: 9743565
    Abstract: An electrical component with conductive material(s) that is suitable for use within the electromagnetic field path of a wireless power transfer system. The electronic component includes conductive materials that are sufficiently thin to absorb no more than an acceptable amount of the electromagnetic field, yet thick enough to remain sufficiently conductive to perform the desired electrical function. In embodiments in which the wireless power supply delivers up to 20 watts of power, the conductive materials are not substantially thicker than about 1/10 the skin depth of the material at the anticipated wireless power frequency. The electrical component may be disposed at any location between the wireless power supply transmitter and the remote device receiver. The present invention permits the use of a wide rang of electrical components in the field path, such as a display, a sensor or a component capable of selectively operating as both.

  • Patent number: 9699928
    Abstract: An item of print media (30) including an inductive secondary (50) for providing power to a load (32). The inductive secondary is responsive to an electromagnetic flux to generate a time-varying current or voltage therein. The current or voltage induced in the inductive secondary directly or indirectly powers the load to thereby enhance the functionality and/or the appeal of the item of print media without significantly adding to its cost. The load can provide a visual and/or auditory output, and can include an electroluminescent display, an e-ink display, a piezo speaker coil, an electrostatic speaker, an OLED, an LED or an LCD display. Embodiments of the invention can be utilized in connection with a wide variety of print media, including for example books, booklets, pamphlets, labels, magazines, manuals, brochures, maps, charts, posters, journals, newspapers or loose leaf pages.

  • Patent number: 9344155
    Abstract: A system and method for mitigating interference between two or more inductive systems. Interference can be mitigated by, in response to an interference causing event, temporarily adjusting operation of one or more of the inductive sub-systems to reduce interference. A controller can receives communication from multiple inductive systems and instruct the systems to operate so as to reduce interference. The inductive systems can coordinate to operate out of phase with respect to one another to reduce interference. Communication from a data transfer inductive system can be mimicked by another inductive system so that both systems transmit the communication. Interference between multiple inductive systems can be mitigated by specific physical positioning of the transmitters of the inductive sub-systems.

  • Patent number: 8847546
    Abstract: An inductive power supply system to wirelessly charge a remote device based on detected battery characteristics. The system includes an inductive power supply with a primary coil capable of inductively providing power to a secondary coil in a remote device. The inductive power supply and remote device include communication means for wirelessly communicating. The system further includes a remote device, having a battery with detectable battery characteristics. In operation, the remote device is capable of detecting the battery characteristics by applying a qualification charge to the battery. The inductive power supply system is capable of identifying the battery installed in the remote device by analyzing the detected battery characteristics. The inductive power supply system selects an appropriate charging algorithm based on the analyzed characteristics.
